Description
BACKGROUND OF THE INVENTION
Field of the Invention

The present invention generally relates to children's games and, in particular, to interactive games, toys and play systems utilizing wireless transponders and receivers for providing a unique interactive game play experience.


Description of the Related Art

Games, toys, play systems and other similar entertainment devices are well known for providing play and interaction among children and adults. A variety of commercially available play toys and games are also known for providing valuable learning and entertainment opportunities for children, such as role playing, reading, memory stimulation, tactile coordination and the like. However, there is always a demand for more exciting and entertaining games and toys that increase the learning and entertainment opportunities for children and stimulate creativity and imagination.


SUMMARY OF THE INVENTION

Embodiments of the present invention provide a unique play experience carried out utilizing an interactive gaming toy that allows play participants to wirelessly interact with their surrounding play environment(s). The gaming toy may be used to play a game carried out in a physical play environment, such as a play structure, play area or other area (either commercial or residential), as desired. It may also be used to play a game carried out in non-physical play environments, such as television, radio, virtual reality, computer games and the like. The physical play environment may be simply a themed play area, or even a multi-purpose area such as a restaurant dining facility, family room, bedroom or the like. The non-physical play environment (sometimes referred to herein as a “virtual” play environment) may be an imaginary environment (i.e., computer/TV generated). For example, a virtual play environment may be visually/aurally represented via computer animation. Optionally, multiple play participants, each provided with a suitable interactive gaming toy, may play and interact together to achieve desired goals, master certain skills and/or produce desired effects within the play environment.


In one embodiment an interactive gaming toy is provided comprising a physical toy, such as a toy wand, doll or action figure, configured with an RFID (radio frequency identification) transponder (sometimes referred to herein as a “tag”) pre-programmed with a unique identifier. The unique identifier may uniquely identify the toy within an associated game, for example. The RFID tag may also be configured to store information describing certain attributes or abilities of a corresponding virtual character or object in a computer-animated game. The information stored on the RFID tag may also be supplemented or updated as the corresponding virtual character or object evolves or changes over time based on player performance and/or gameplay progression. The interactive gaming toy thus allows developed character attributes and the like to be stored and easily transported to other games and compatible gaming platforms.


In accordance with another embodiment an interactive gaming toy comprises a toy wand or other seemingly magical object which provides a basic foundation for a complex, interactive entertainment system. In one embodiment the toy wand comprises an elongated hollow pipe or tube having a proximal end or handle portion and a distal end or transmitting portion. An internal cavity may be provided to receive one or more batteries to power optional lighting, laser or sound effects and/or to power long-range transmissions such as via an infrared LED transmitter device or RF transmitter device. The handle portion and/or distal end of the toy wand may be fitted with an RFID transponder that is operable to provide relatively short-range RF communications (<60 cm) with one or more compatible receivers or transceivers. In one embodiment the transponder is pre-programmed with a unique identifier which may be used, for example, to identify and track individual play participants and/or wands within a play facility.


The RFID transponder or other identifying device is preferably used to store certain information identifying each play participant and/or describing certain powers or abilities possessed by an imaginary role-play character. In one embodiment players may advance in a magic-themed adventure game by finding clues, casting spells and solving various puzzles presented. Players may also gain (or lose) certain attributes, such as magic skills, magic strength, fighting ability, various spell-casting abilities, and combinations of the same or the like. All of this information is preferably stored on the RFID transponder and/or an associated database indexed by the unique RFID tag identifier so that the character attributes may be easily and conveniently transported to other similarly-equipped play facilities, computer games, video games, home game consoles, hand-held game units, and the like. In this manner, an imaginary role-play character is created and stored on a transponder device that is able to seamlessly transcend from one play environment to the next.


In accordance with another embodiment one or more adjunct gaming items are provided, comprising collectable/tradable character cards, trinkets, tokens, coins, or the like. Each character card (or trinket, token, coin, etc.) may be configured with an RFID tag that stores certain information describing the powers or abilities of an imaginary role-play character that the gaming toy represents. In one embodiment, as each play participant uses a favorite character card to play a game in a compatible play facility, for example, the character represented by the card gains (or loses) certain attributes, such as magic skill level, magic strength, flight ability, various spell-casting abilities, etc. All of this information is preferably stored on the card so that the character attributes may be easily and conveniently transported to other similarly-equipped play facilities, computer games, video games, home game consoles, hand-held game units, and the like. In this manner, an imaginary role-play character is created and stored on a card that is able to seamlessly transcend from one play medium to the next.


In accordance with another embodiment one or more adjunct gaming items are provided, comprising trading cards depicting various real or imaginary persons, characters and/or objects. In one embodiment each card has recorded or stored thereon in an electronically readable format certain selected information pertaining to the particular person, character or object, such as performance statistics, traits/powers, or special abilities. The information is preferably stored on an RFID tag associated with each card and which can be read electronically and wirelessly over a predetermined range preferably greater than about 1 cm when placed in the proximity of a suitably configured RF reader. Optionally, the RFID tag may be read/write capable such that the information stored thereon may be changed or updated in any manner desired.


In accordance with another embodiment a computer adventure game is provided wherein game participants use RFID-enabled tokens as player tracking devices within the game. Each token has an RFID tag that uniquely identifies a corresponding player in the game and also preferably stores the player's progress in the game. Each player begins the adventure with essentially the same powers, skills and abilities. Each player may also receive an interactive gaming toy which the player must learn to use to accomplish certain goals set out in the game.


An authenticating password system may be used to verify or authenticate game events and to thereby discourage cheating. Authenticating passwords may be unique or semi-unique to the player(s) who possess them. For example, each password may be an encrypted alpha-numeric code that is mathematically derived from a unique ID number stored on each participating player's token. When the alpha-numeric number is subsequently re-entered into another device (for example, a home game console or home computer) by the authorized player, the game software can reverse the mathematical encryption algorithm using the player's unique ID number and thereby determine and/or validate the game event(s) that generated the authenticating password.


In accordance with another embodiment an RFID-enabled gaming system is provided that allows a game participant to earn points, levels, or upgrades in a first game, which are stored on an associated RFID-enabled token. The game participant is then able to use the RFID-enabled token and the stored points, levels, or upgrades to advance in a second RFID-enabled game. Players may also earn upgrades by purchasing certain retail items from a participating retail vendor, such as a fast-food restaurant. For example, a player may receive a token and/or an authenticating code in one or more retail transactions that enables the game participant to access levels, or upgrades in a popular video game. Authenticating codes may be printed on an ordinary cash register receipt, for example.


For purposes of summarizing the invention and the advantages achieved over the prior art, certain objects and advantages of the invention have been described herein above. Of course, it is to be understood that not necessarily all such objects or advantages may be achieved in accordance with any particular embodiment of the invention. Thus, for example, those skilled in the art will recognize that the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other objects or advantages as may be taught or suggested herein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

For convenience of description and for better clarity and understanding of the invention similar elements to those previously described may be identified with similar or identical reference numerals. However, not all such elements in all embodiments are necessarily identical as there may be differences that become clear when read and understood in the context of each particular disclosed preferred embodiment.


Interactive Gaming Toys



FIGS. 1A and 1B illustrate the basic construction of one embodiment of an interactive gaming toy 100a having features and advantages in accordance with the present invention. The gaming toy 100a generally comprises a portable toy figure or object 110a embodying, for example, a mythical creature such as a dragon 110a. Preferably, the toy figure or object 110a is small enough to be easily transported and manipulated by play participants, but not so small as to present a choking hazard for young children. If desired, the toy figure or object 110a may be mounted on and/or supported by a supporting structure 115a, as illustrated. This may be separately formed or integrally formed with the toy figure or object 110a as expedient or desired.


The toy figure or object 110a is preferably uniquely identified using one or more embedded or affixed RFID tags (described in more detail later). In one embodiment a glass-encapsulated RFID transponder 118 is disposed within an inner cavity formed within the toy figure or object 110a and/or supporting structure 115a. Transponder 118 is preferably passive (batteryless) and is operable to provide relatively short-range RF communications (less than about 200 cm) using one or more compatible RFID reader units or reader/writer units (described in more detail later). In one embodiment the transponder 118 is pre-programmed with a unique tag identifier and comprises non-volatile memory configured to store certain information identifying a play participant and/or describing certain powers or abilities possessed by an imaginary role-play character.


For example, players may advance in a magic-themed adventure game by finding clues, casting spells and solving various puzzles presented. Players may also gain (or lose) certain attributes, such as magic skills, magic strength, fighting ability, various spell-casting abilities, combinations of the same or the like, based on game play, skill-level and/or the purchase of collateral play objects. Some or all of this information is preferably stored on the RFID transponder 118 so that the character attributes may be easily and conveniently transported to various compatible play facilities, games, video games, home game consoles, hand-held game units, and the like. Alternatively, some or all of this information may be stored on a computer-accessible database indexed by the unique tag identifier.


The toy figure or object 110a and/or supporting structure 115a may further include securement means, such as threaded stud 121, snap latches, mating magnets or the like, for receiving and securing one or more auxiliary components, such as a detachable knob 123a. For example, such auxiliary components may be purchased, selected and/or earned by play participants as they advance in a game and/or when they play different games. One example of an assembled gaming toy 100a is shown in FIG. 1B.



FIGS. 2A and 2B illustrate possible alternative embodiments of an interactive gaming toy 100b (FIG. 2A), 100c (FIG. 2B) having features and advantages in accordance with the present invention. As with the gaming toy 100a illustrated and described above, each interactive gaming toy 100b and 100c comprises a portable toy FIG. 110b, 110c embodying a mythical creature, such as a pixie 110b (FIG. 2A) or a unicorn 110c (FIG. 2B). These may be the same size or different sizes than the toy FIG. 110a (see FIG. 1), as desired.


The gaming toy 100b (FIG. 2A) also includes a glass-encapsulated transponder 118 pre-programmed with a unique tag identifier and having non-volatile memory configured to store certain information identifying a play participant and/or describing certain powers or abilities possessed by an imaginary role-play character. Transponder 118 is disposed within an auxiliary component comprising a detachable knob 123b. For example, the transponder 118 may be encapsulated in a colored epoxy, Lucite® acrylic glass (polymethyl methacrylate or PMMA) or the like and thereby disguised as a natural crystal or mineral/stone forming part of the detachable knob 123b. The knob 123b may include a magnet 117a and the toy figure or object 110b and/or supporting structure 115b may include a mating magnet 117b configured to removably secure the knob 123b and/or other compatibly-configured auxiliary components.


The gaming toy 100c (FIG. 2B) may share a similar construction to the gaming toy 100a or 100b illustrated and described above. The gaming toy 100c further comprises an intermediate auxiliary component 125 positioned between the supporting structure 115c and the detachable knob 123c. This may be used as a handle, for example, for holding or carrying the gaming toy 100c. Optionally, the intermediate auxiliary component 125 may include a second RFID tag, such as an adhesive-backed RFID tag inlay 128 (described in more detail later) which may be affixed to the intermediate auxiliary component 125 and covered with an adhesive paper label 127. Alternatively, the RFID tag inlay 128 may be molded directly into a substrate from which the intermediate auxiliary component 125 is formed.


Another possible embodiment of an interactive gaming toy is illustrated in FIGS. 3A-3B. The interactive gaming toy 100d generally comprises a key chain trinket 110d depicting, for example, a mythical character such as a magical wizard. The key chain trinket 110d may be mounted on a key chain 115d, as illustrated, for removably attaching the gaming toy 100d to a key ring (not shown). The key chain trinket 110d is uniquely identified by an adhesive-backed RFID tag inlay 128 which is affixed to the back side of the key chain trinket 110d, as illustrated in FIG. 3B. Alternatively, the RFID tag inlay 128 may be molded directly into the substrate from which the key chain trinket 110d is formed. The RFID tag 128 is preferably pre-programmed with a unique tag identifier and contains non-volatile memory configured to store certain information identifying a play participant and/or describing certain powers or abilities possessed by an imaginary role-play character.


For example, character attributes developed during a play participant's visit to a local play facility may be stored on the tag 128. When the play participant then revisits the same or another compatible play facility, all of the attributes of his character are “remembered” on the tag 128 so that the play participant is able to continue playing with and developing the same role-play character. Similarly, various video games, home game consoles, and/or hand-held game units can be and preferably are configured to communicate with the tag 128 in a similar manner as described above and/or using other well-known information storage and communication techniques. In this manner, a play participant can use the same role play character he or she has developed with specific associated attributes in a favorite video action game, role-play computer game or the like.


Another possible embodiment of an interactive gaming toy is illustrated in FIG. 4. The interactive gaming toy 100e generally comprises a toy figure or doll 110e embodying, for example, a mythical character such as a gnome. The toy figure or doll 110e may be mounted on and/or supported by a supporting structure 115e, in this case a simulated stack of books. The supporting structure 115e may be separately formed or integrally formed with the toy figure or doll 110e as expedient or desired. The toy figure or doll 110e is uniquely identified using an adhesive-backed RFID tag inlay 128 which is affixed to an outer surface of the toy FIG. 110e or supporting structure 115e. Alternatively, the RFID tag inlay 128 may be molded directly into the substrate from which the toy FIG. 110e or supporting structure 115e is formed. The RFID tag 128 is preferably pre-programmed with a unique tag identifier and contains non-volatile memory configured to store certain information identifying a play participant and/or describing certain powers or abilities possessed by an imaginary role-play character.


Another possible embodiment of an interactive gaming toy is illustrated in FIG. 5. The interactive gaming toy 100f generally comprises a toy action FIG. 110f embodying, for example, a mythical creature such as a dragon. The toy action FIG. 110f is uniquely identified using a glass-encapsulated RFID transponder 118 which is disposed within an inner cavity formed within the toy action FIG. 110f. The transponder 118 is preferably pre-programmed with a unique tag identifier and comprises non-volatile memory configured to store certain information identifying a play participant and/or describing certain powers or abilities possessed by an imaginary role-play character.


For example, play participants may use the gaming toy 100f to electronically and “magically” interact with their surrounding play environment to achieve desired goals or produce desired effects within a suitably-configured play environment. Use of the gaming toy 100f may be as simple as touching it to a particular surface or “magical” item within the play environment or it may be as complex as moving or shaking the gaming toy 100f in a particular manner and/or orienting it relative to a certain item desired to be “magically” transformed or otherwise affected. For example, various wireless receivers (described in more detail later) may be provided within a physical play environment and configured so as to allow play participants to activate various associated play effects and/or to play a game using the gaming toy 100f. As play participants play and interact within each play environment they learn more about the “magical” powers possessed by the gaming toy 100f and become more adept at using the gaming toy 100f within various game contexts to achieve desired goals or produce desired play effects. Optionally, play participants may collect points or earn additional magic levels or ranks for each play effect or task they successfully achieve. In this manner, play participants may compete with one another to see who can score more points and/or achieve the highest magic level.


If desired, an optional RF/IR module 150 (described in more detail later) may be provided for long-range wireless communications (up to about 100 meters). If line of sight or directional actuation is desired, an infrared LED transmitter of the type employed in standard television remote controls may be provided instead of or in addition to an RF transmitter, as those skilled in the art will readily appreciate. Of course, a wide variety of other wireless communications devices, as well as various optional sound and lighting effects may also be provided, as desired.


Operation of the RF/IR module 150 (and/or other wireless communication devices described herein) may be controlled by motion-sensitive internal activation circuitry 120 (described in more detail later). For example, activation circuitry 120 may be configured to allow the gaming toy 100f to be operated by moving or manipulating it in a particular manner. If provided, these operational aspects would need to be learned by play participants as they train in the various play environments. One goal, for example, may be to become a master dragon trainer. This means that the play participant has learned and mastered every aspect of operating the gaming toy 100f to produce desired effects within each play environment. Of course, additional effects and operational nuances can (and preferably are) always added over time in order to keep the interactive experience fresh and continually changing. The gaming toy 100f may also be configured to respond to other signals, such as light, sound, or voice commands as will be readily apparent to those skilled in the art.


Another possible embodiment of an interactive gaming toy is illustrated in FIG. 6. The interactive gaming toy 100g generally comprises a toy wand comprising a wand shaft 110g and one or more auxiliary components such as a detachable handle 115g and a detachable knob 123g. The toy wand 100g is uniquely identified using a glass-encapsulated RFID transponder 118 which is disposed within an inner cavity formed in the wand shaft 110g or detachable handle 115g. Preferably the transponder 118 is pre-programmed with a unique tag identifier and comprises non-volatile memory configured to store certain information identifying a play participant and/or describing certain powers or abilities possessed by an imaginary role-play character.


Play participants may use the toy wand 100g to electronically and “magically” interact with a suitably configured play environment to achieve desired goals or produce desired effects. For example, FIGS. 7A-7B illustrate one embodiment of a magic-themed play environment comprising multiple play effects 200, such as a talking rabbit 201, a magic hat 202, a crystal ball 203, an enchanted book 204, and a shooting-gallery-style play effect 205 having one or more targets 206. These may be physical play objects configured with special effects and/or they may be graphical or computer-generated images displayed, for example, on one or more associated computer monitors, TV monitors, DVD display monitors, or computer gaming consoles and the like. Those skilled in the art will readily appreciate from the disclosure herein that all of these effects and many other possible play effects may be actuated or controlled by toy wand 100g in conjunction with one or more RF receivers, RFID reader/writers and/or other devices disclosed and described herein.


Use of the toy wand 100g may be as simple as touching it to a particular surface or “magical” item within the play environment or it may be as complex as moving or manipulating the toy wand 100g in a particular manner and/or pointing it accurately at a certain item desired to be “magically” transformed or otherwise affected. For example, various wireless receivers (described in more detail later) may be distributed throughout a play facility so as to allow play participants to activate various associated play effects and/or to play a game using the toy wand 100g. As play participants play and interact within each play environment they learn more about the “magical” powers possessed by the toy wand 100g and become more adept at using the toy wand 100g within various game contexts to achieve desired goals or produce desired play effects. Optionally, play participants may collect points or earn additional magic levels or ranks for each play effect or task they successfully achieve. In this manner, play participants may compete with one another to see who can score more points and/or achieve the highest magic level. Play participants may also access a web site in order to register the toy wand and play an online interactive game. Preferably this is a relatively simple game intended to provide a basic training session. In this on-line game session, the player may learn how to use the toy wand 100g to cast various spells and trigger various effects within an interactive computer-gaming environment provided by an ordinary home computer. The player may also learn how to discover important clues needed to advance in the game and to solve various puzzles or challenges presented by the game.


If desired, an optional RF/IR module 150 (described in more detail later) may be provided for long-range wireless communications (up to about 100 meters), as illustrated in FIG. 6. If line of sight or directional actuation is desired, an infrared LED transmitter of the type employed in standard television remote controls may be provided instead of or in addition to an RF transmitter, as those skilled in the art will readily appreciate. Of course, a wide variety of other wireless communications devices, as well as various optional sound and lighting effects may also be provided, as desired. Operation of the RF/IR module 150 (and/or other wireless communication devices described herein) may be controlled by motion-sensitive internal activation circuitry 120 (described in more detail later). For example, activation circuitry 120 may be configured to allow the toy wand 100g to be operated by waving, shaking, stroking and/or tapping it in a particular manner. If provided, these operational aspects would need to be learned by play participants as they train in the various play environments. One goal, for example, may be to become a “grand wizard” or master of the wand. This means that the play participant has learned and mastered every aspect of operating the toy wand 100g to produce desired effects within each play environment.


Of course, additional effects and operational nuances can (and preferably are) always added over time in order to keep the interactive experience fresh and continually changing. Optionally, the toy wand 100g may be configured with an LCD display screen (not shown). The toy wand 100g may also be configured to respond to other signals, such as light, sound, or voice commands as will be readily apparent to those skilled in the art. Additional preferred embodiments, details and functionalities of the toy wand 100g are described below, having reference to FIGS. 8-12.


As illustrated in more detail in FIG. 8A, the toy wand 100g essentially comprises an elongated hollow pipe or tube 111 having a proximal end 112 and a distal end 114. An internal cavity 116 is preferably provided to receive and safely house various circuitry for activating and operating the toy wand and various wand-controlled effects (described later). Batteries, optional lighting, laser or sound effects and/or the like may also be provided and housed within cavity 116, if desired, as will be described in more detail later. An optional button (not shown) may also be provided, if desired, to enable particular desired functions, such as sound or lighting effects or longer-range transmissions. While a hollow metal or plastic tube 111 is preferred, it will be appreciated that virtually any other mechanical structure or housing may be used to support and contain the various components and parts described herein, including integrally molded or encapsulated containment structures such as epoxy resins and the like. If a metal tube is selected, care must be taken to ensure that it does not unduly interfere with any of the magnetic, RFID or RF/IR devices described herein. Thus, for example, any RF antennas should preferably be mounted near or adjacent an end opening and/or other opening of the tube 111 to ensure adequate operating range and desired directionality.


The proximal end 112 of tube 111 is preferably adapted to secure the tube 111 to an optional handle 115g or other mating component. The handle 115g may further include securement means, such as threaded stud, snap latches, mating magnets 117a, 117b or the like, for receiving and securing an optional decorative knob 123g. For example, knobs 123g may be purchased, selected and/or earned by play participants as they advance in a game and/or when they play different games. An RFID transponder 118 is provided and contained within the wand shaft 110g and/or in the handle 115g, as illustrated. The transponder 118 is pre-programmed with a unique identifier such as a unique person identifier number (“UPIN”). The UPIN may be used to identify and track individual toy wands 100g and/or play participants. Optionally, each tag 118 may also include a unique group identifier number (“UGIN”) which may be used to match a defined group of individuals having a predetermined or desired relationship.


The RFID transponder 118 is preferably used to store certain information identifying each play participant and/or describing certain powers or abilities possessed by an imaginary role-play character. For example, players may advance in a magic adventure game by finding clues, casting spells and solving various puzzles presented. Players may also gain (or lose) certain attributes, such as magic skills, magic strength, fighting ability, various spell-casting abilities, combinations of the same or the like, based on game play, skill-level and/or the purchase of collateral play objects. Some or all of this information is preferably stored on the RFID transponder 118 so that the character attributes may be easily and conveniently transported to various compatible play facilities, games, video games, home game consoles, hand-held game units, and the like. Alternatively, only the UPIN and/or UGIN are stored on the transponder 118 and all other desired information is stored on a computer-accessible database indexed by UPIN and/or UGIN, for example. Placing the RFID tag 118 in the handle 115g, as illustrated, allows for modular construction and functionality of the toy wand 100g as auxiliary handles may be interchanged having other unique RFID tags with unique stored information. Optionally, the tag-containing handle 115g and knob 123g may be omitted altogether in the case, for example, where a less expensive toy wand is desired.


An optional RF/IR module 150 (described in more detail later) may be provided for long-range wireless communications (up to about 100 meters). If line of sight or directional actuation is desired, an infrared LED transmitter of the type employed in standard television remote controls may be provided instead of or in addition to an RF transmitter, as those skilled in the art will readily appreciate. In the latter case, a hole (not shown) would preferably be provided in the distal end 114 of the shaft 110g to accommodate the transmitting LED of the IR transmitter circuit (described in more detail later). Of course, a wide variety of other wireless communications devices, as well as various optional sound and lighting effects may also be provided, as desired.


Operation of the RF/IR module 150 (and/or other wireless communication devices described herein) may be controlled by internal activation circuitry comprising, in the particular embodiment illustrated, a pair of series-connected tilt sensors 122 and 124 (represented in the corresponding schematic diagram as switches S1 and S2, respectively). For example, a pair of micro-ball tilt sensors may be arranged within the cavity 116 in opposite orientations and spaced apart, as illustrated. Those skilled in the art will appreciate that in virtually any static position of the toy wand 100g at least one of tilt sensors 122, 124 will be in the OFF state. Thus, the RF/IR module 150 can essentially only be activated when the toy wand 100g is in a non-static condition or, in other words, when it is in motion. The placement and orientation of the tilt sensors 122, 124 is preferably such that different accelerations or motions are required at the proximal and distal ends 112 and 114 in order for both tilt sensors 122, 124 to be in their ON positions (or OFF positions, as the case may be) and, thus, to enable or activate RF/IR module 150 (or other wireless communication devices described later).


Of course, those skilled in the art will appreciate from the disclosure herein that the activation circuitry is not limited to those including micro-ball tilt sensors, as illustrated, but may be practiced using a wide variety of other motion and/or tilt sensors and/or other supporting circuitry elements and components that are selected and adapted to the purposes described herein. These include, without limitation, gyro-sensors, vibration sensors, and accelerometers. Moreover, any one or more of these and/or other similar sensor devices may also be used in conjunction with other supporting circuitry elements or components (either internal or external to the toy wand 100g) as desired, including microprocessors, computers, controller boards, PID circuitry, input/output devices, combinations of the same and the like.


Those skilled in the art will also readily appreciate and understand from the disclosure herein that various additional and/or alternative activation circuits can be designed and configured so as to respond to different desired motions. For example, this may be achieved by adding more sensors and/or by changing sensor positions and orientations. For example, one motion may trigger a first activation circuit (and a first interactive play effect) while a different motion may trigger a second activation circuit (and a second interactive play effect). The number, type and complexity of motions and corresponding activation circuits are limited only by design and cost considerations and user preferences. Of course, those skilled in the art will recognize from the disclosure herein that multiple activation circuits may share one or more sensors and/or other supporting circuitry and components, as required or desired. Alternatively, a single, multi-mode activation circuit may be provided that can respond to multiple motions.


Furthermore, the activation circuit may comprise a microprocessor that communicates with the sensors 122, 124 and the transmitter module 150. In one embodiment, the microprocessor receives at least one signal from the sensors 122, 124 indicative of the state of the sensors. For instance, the microprocessor may determine when each of the sensors 122, 124 are in an ON or an OFF state or when one of the sensors 122, 124 switches states. Based on the states of the sensors 122, 124, the microprocessor then outputs a signal to the transmitter module 150 that causes activation or deactivation of the transmitter module 150.


In another embodiment, the microprocessor is capable of measuring a duration of time related to the operational states of the sensors 122, 124. For example, the microprocessor may use a clock signal or an external timer to determine the duration of time during which at least one of the sensors 122, 124 is in an ON state. The microprocessor may then use this duration of time when outputting a signal to the transmitter module 150. For example, the microprocessor may correlate the duration of time that a sensor 122, 124 is activated (for example, in an ON state) with an intensity, level, or type of a “spell” being cast by the user. For instance, if the user, while “casting a spell,” is able to move the toy wand 100g so as to keep at least one of the sensors 122, 124 activated for a certain period of time, the microprocessor may assign a particular level or intensity to the spell being cast. Thus, the microprocessor may output different signals, which represent different spells or spell intensities, to the transmitter module 150 based on the length of time of the sensor activation. In one embodiment, the microprocessor may associate longer durations of sensor activation with higher intensity spells.


In yet other embodiments of the invention, the duration of time during or between activation of the sensors 122, 124 is output to a receiver external to the wand 100. The receiver then processes the duration of time in determining which effect, or which level of an effect, is caused by the particular wand activation motions and associated duration(s) of time. In yet other embodiments, the foregoing microprocessor may be used in a toy wand 100g comprising a transponder 118 instead of, or in combination with, the transmitter module 150.


If desired, the RFID transponder 118 may also be electronically interlocked and controlled by an activation circuit such as illustrated and described above. For example, the RFID transponder 118 may be selectively activated or deactivated via an optional external interrupt/disable line 260 (see FIG. 15A). More preferably, however, the tag 118 is not interlocked, but is always activated. In this manner, transponder 118 can be easily read at short range (<60 cm) using an RFID reader/writer (described later) to sense and track play participants and/or to activate various simple effects.


In another embodiment, the wand 100g may be configured to operate in an “active” mode or a “sleep” mode. During the sleep mode, the activation circuit does not engage in significant activity, which reduces the energy consumption of the toy wand 100g. However, when the RFID tag 118 is brought within range of an RF transmitter, such as positioned near an effects controller, the RFID tag 118 receives a transmitted RF signal and “awakens” the activation circuit into the “active” state. If desired, the toy wand 100g may be further configured with a light or sound effect capable of producing a perceptible signal, such as a light or a noise, to alert the user when the toy wand 100g awakens to an “active” mode.


The toy wand 100g may be powered by one or more internal batteries (not shown). Optionally, it may be powered by an external energy source such as via a magnetic inductance energy generator 162. The magnetic inductance energy generator 162 comprises an inductance coil L1 sized and arranged such that when it is exposed to a fluctuating magnetic field (for example, a moving permanent magnet 164 rubbed back and forth and/or an externally generated electromagnetic field) an alternating current is generated. This generated current is rectified by diode D1 or, alternatively, a full wave bridge rectifier (not shown), and charges preferably an electrolytic capacitor C1 until it reaches a predetermined operating voltage (V+). If desired, a voltage regulator device, such as a zener diode (not shown) and/or active regulation circuitry may be added to stabilize and increase the efficiency of the magnetic inductance energy generator 162.


Alternatively, those skilled in the art will appreciate from the disclosure herein that various magnetic field effect sensors, such as Wiegand sensors and the like, may readily be used in place of or in addition to inductor L1 where, for example, it is desired to increase the energy-generating efficiency of the circuit 162. For example, U.S. Pat. No. 6,191,687 to Dlugos discloses a Wiegand effect energy generator comprising a Wiegand wire that changes its magnetic state in response to being exposed to an alternating magnetic field. The Wiegand wire has core and shell portions with divergent magnetic properties. The magnetic properties of the wire are such that it produces an output power signal that corresponds to the strength and rate of change of a magnetic field to which the Wiegand wire is exposed. Such energy pulses generally are between about 5 and 6 volts and 10 microseconds in width. Such energy pulses have sufficient voltage and duration to power a low power transmitter such as RF/IR module 150. One suitable Wiegand sensor that may be utilized in accordance with the present invention is the series 2000 sensor sold by EHD Corp. The Series 2000 Wiegand sensor produces pulses in response to alternating magnetic fields or permanent magnets that pass near the sensor. Alternatively, a piezoelectric energy generator (not shown) may be substituted for the magnetic inductance energy generator 162. See, for example, FIGS. 9-11 of U.S. Pat. No. 9,039,533 and the accompanying discussion.


The energy generating circuit 162 is preferably such that the toy wand 100g has no movable parts and requires no maintenance such as replacing batteries or the like over its anticipated life. All energy is generated, for example, by placing the toy wand within an externally generated electromagnetic field. Preferably, the inductor L1 (or Wiegand wire) and capacitor C1 are selected such that 5-10 seconds of exposure to an external fluctuating magnetic field will fully charge the capacitor C1, thus enabling the RF/IR transmitter 150 to be activated at least once and preferably 5-20 times without having to recharge. Advantageously, the absence of replaceable batteries or other visible electronic technology significantly increases the reality and full immersion experience of the magical fantasy and gives users the feeling of practicing, performing and mastering “real” magic using a “real” magic wand. Optionally, a non-replaceable permanent rechargeable battery and/or a factory replaceable battery (not shown) may be provided in place of or in addition to the energy generating circuit 162 where it is desired to provide long-term energy storage.


In certain applications, it may be desirable to wirelessly communicate specific data and commands to achieve different or varied interactive effects. For example, it may desirable to wirelessly send one command signal that turns a certain object (for example, a lamp) “OFF” and another command signal that turns an object “ON.” As described above, this functionality may be achieved using multiple activation circuits (or a single multi-mode activation circuit) responsive to various motions whereby each motion, if executed successfully, causes a different RF or IR signal to be transmitted to control or activate the desired effect (for example, turning a light ON or OFF or simulating the levitation of an object).


Another convenient way to achieve similar functionality is to load data bits representing specific desired commands directly into a data buffer of RF/IR module 150 and then, using only a single wand activation circuit and a single learned wand motion, cause an RF or IR signal to be transmitted, thereby carrying the command signal and data to an RF or IR receiver and associated effect. In one embodiment, one or more tilt sensors 192, 194 (illustrated schematically as switches S3/S4) may be provided in a convenient location within the toy wand 100g (for example, within the handle 115g). These sensors are preferably mounted and oriented at different angles from one another such that axial rotation of the wand shaft 110g and/or wand handle 115g causes the sensors to alternately switch from their ON to their OFF state. As illustrated in the circuit schematic accompanying FIG. 8A, each sensor controls one data input bit of the RF/IR module data bus (for example, S3, S4). Those skilled in the art will readily appreciate that in this manner, four possible wand orientations are possible resulting in four unique sensor pair states as follows: ON/ON; OFF/OFF; ON/OFF and OFF/ON. These four sensor states can represent, for example, four unique command signals sent using the RF/IR module 150. Where it is desired to send a larger number of unique command signals, various combinations of additional orientation sensors and/or activation circuits may be added, as desired. Alternatively, various dials, switches and/or other inputs may be provided for selecting from a number of unique commands or “spells.”


In one embodiment an auxiliary component 207 is provided and is configured with optional touch sensor elements 208, 210, 212 for selecting one or more commands. Touch sensor elements 208, 210, 212 (represented in the accompanying schematic as S3, S4, S5) comprise solid-state electronic switches (no buttons or moving parts) that are activated by the simple touch of a finger. Most preferably, these are solid state touch switches of the type illustrated and described in U.S. Pat. No. 4,063,111 to Dobler et al., the entire contents of which are incorporated herein by reference. As illustrated in more detail in FIG. 8B, each touch switch contact element 208, 210, 212 is preferably formed from a pair of conductive electrodes 211 surrounded by, and preferably flush with, an insulating material 213. If desired, the electrodes 211 may be shaped in the form of magic symbols or other shapes consistent with a desired magic theme, as illustrated. During use, the user's finger is placed over the pair of electrodes 211 and thereby forms a portion of an electronic circuit to change the state of a corresponding solid state electronic switching device Q1, Q2, Q3 in communication therewith, such as a MOSFET or PNP transistor. The touch sensor is thereby actuated.


Each touch sensor preferably controls one data input bit of the RF/IR module data bus (for example, S3, S4, S5). One or more touch switches 208, 210, 212 may be activated during a single transmission. Thus, those skilled in the art will readily appreciate that eight possible combinations of touch switch activations are possible corresponding to eight unique command input data sets as follows: ON/ON/ON; OFF/OFF/ON; ON/OFF/ON, OFF/ON/ON, ON/ON/OFF; OFF/OFF/OFF; ON/OFF/OFF, and OFF/ON/OFF These eight sensor states can represent, for example, eight unique command signals sent using the RF/IR module 150.


Optionally, toy wand 100f may include a magnetic tip 216, as illustrated in FIG. 8A. This can be especially useful and entertaining for close-range activation of various play effects, such as turning lights on/off, triggering special sound and/or lighting effects. For example, FIGS. 9A-9B are time-sequenced illustrations of one embodiment of a magnetically actuated lighting effect using the interactive wand toy 100g with optional magnetic tip 216. A magnetic reed switch 218 is provided in series between the desired lighting effect 226 and a power source (V+). The reed switch is constructed in the normal fashion. Contacts 222, 224 are normally open and, thus, the lighting effect 226 is in its OFF state. But, when the magnetic tip 216 of wand 100g is brought into relatively close proximity (2-3 cm) with the reed switch 218, contact elements 222, 224 are magnetized by the magnetic field lines and are drawn toward each other. This causes the contacts 222, 224 to immediately attract, closing the gap and completing the circuit to turn on the lighting effect 226. Of course, those skilled in the art will appreciate from the disclosure herein that various relays, power controllers and the like may be required or desirable to provide adequate control of larger, more complex effects. But all such effects, no matter how small/simple or large/complex, may be triggered with a simple reed switch 218 and a wand 100g having a magnetic tip 216, as described above.


The magnetic tip 216 is especially useful and synergistic in combination with the other disclosed functions and features of wand 100g. Thus, for example, as illustrated in FIG. 9C, a desired lighting effect 226 is controlled by RF/IR receiver 250 (described in more detail later), which is adapted to receive an RF and/or IR command signal from wand 100g. The RF/IR receiver 250 (and/or the lighting effect 226) is also controlled by series-connected magnetic reed switch 218, as illustrated and described above (FIGS. 9A, 9B). Desirably, this allows a user to use the wand 100g and the magnetic tip 216 thereof to select one or more effects he or she wishes to control or activate. For example, the closure of the magnetic reed switch 218 may send an activation signal to RF/IR receiver 250. In response, the receiver initiates a timer (for example, 5-10 seconds) wherein its RF and/or IR receiver circuitry is activated and ready to receive one or more transmitted commands for controlling the associated effect 226. Thus, a user may select to control the lighting effect 226 by activating the reed switch 218 with the magnetic tip 216 of toy wand 100g. Then the user may cast a spell (cause the wand 100g to transmit an RF or IR command signal) that commands the RF/IR receiver 250 to turn the lighting effect ON or OFF, to change the lighting effect (for example, change its color or intensity), and/or launch a related effect (for example, simulated levitation of the lighting source or other desired effects). In this manner, users can maintain direct and precise control over any number of individual play effects as may be desired.


Preferably, all or most of the components comprising toy wand 100g are standardized, modularized and interchangeable, as illustrated in FIG. 10, so that various prefabricated components and starting materials can be stocked (for example, in a “wizards workshop”) and individually purchased by users to create an endless variety of unique and individualized finished toy wands having evolving powers, abilities and/or aesthetics. Materials and components may be simple in outward appearance and preferably contain no conspicuous outward manifestations (or have only minimal outward manifestations) of the technology within. Materials and components fabricated from natural or simulated natural materials, such as wood, bone and leather, minerals (metals) and crystals are particularly preferred, although certainly not required.


The base component may comprise the wand shaft 110, for example. This may be a hollow plastic, wood or metal shaft provided in various materials and colors. For beginners or entry level users, a finished toy wand may be constructed by simply selecting a wand shaft 110 and then fitting it with one or more magnetic end caps 216, as illustrated. This provides an entry level toy wand (Level-1) that can be used to activate a variety of simple effects such as illustrated and described above in connection with FIGS. 9A-9B. A Level-1 toy wand constructed in this fashion preferably facilitates basic game play within a compatible play facility, but is not fully functional and, therefore, may not be capable of achieving some of the more desirable play effects or play experiences available.


The next level toy wand (Level-2) would preferably include, in addition, a simple passive RFID transponder 118 inserted and secured at one end thereof. The transponder 118 provides relatively short-range RF communications and also stores a unique person identifier number (“UPIN”) and an optional unique group identifier number (“UGIN”). The UPIN and UGIN may be used to identify and track individual wands and play participants. The RFID transponder 118 also stores certain information identifying each play participant and/or describing certain powers or abilities possessed by an imaginary role-play character represented by the wand. These stored character attributes may be easily and conveniently transported with the wand to various compatible play facilities, games, video games, home game consoles, hand-held game units, and the like. If desired, the transponder 118 may be encapsulated in a colored epoxy, Lucite® acrylic glass (polymethyl methacrylate or PMMA) or the like and thereby disguised as a natural crystal or mineral/stone. A Level-2 wand preferably facilitates basic and intermediate game play within a compatible play facility. It has more functionality than a Level-1 wand, but is still not fully functional and, therefore, may not be capable of achieving some of the most desirable play effects or play experiences available.


The next level toy wand (Level-3) would preferably include, in addition, an active RF/IR module 150 and associated activation circuitry 120 for wirelessly casting a simple spell (for example, ON/OFF) over longer distances. Preferably, a Level-3 toy wand would be self-powered, requiring no batteries or other replaceable internal power source. However, if replaceable batteries are desired, they may optionally be encapsulated in a colored epoxy, Lucite® acrylic glass or the like and thereby disguised and sold in the form of a natural “energy crystal” or mineral/stone. A Level-3 toy wand preferably facilitates basic, intermediate and some advanced game play within a compatible play facility. It has more functionality than a Level-1 and Level-2 toy wand and can cast simple spells over long distances, but is not able to cast more complex spells. Therefore, it may not be capable of achieving some of the most advanced and desirable play effects or play experiences available.


The highest level toy wand (Level-4) would preferably include, in addition, circuitry and/or structure(s) (for example, auxiliary component 207) for selecting and casting more advanced and/or complex spells (for example, ON/OFF, increase/decrease, UP/DOWN, change colors, simulated levitation, or the like). For example, this would be similar to the toy wand 100g, illustrated and described above in connection with FIGS. 6-8. Preferably, a Level-4 toy wand would be self-powered, requiring no batteries or other replaceable internal power source. A Level-4 toy wand preferably facilitates basic, intermediate and all advanced game play within a compatible play facility. It has more functionality than a Level-1, Level-2 and Level-3 toy wand and can cast a variety of simple or complex spells over long distances to achieve the most advanced and spectacular magical play effects.


Preferably, in all cases described above, the wand shaft 110, handle 115 and/or knob 123 may be further decorated and/or individualized, as desired, with various decorative elements 129, monograms 131, engravings, stickers, stains, custom paint and the like, to suit the tastes of each individual user. For example, various assembly and fabrication stations may preferably be provided within a dedicated “workshop” area whereby wand purchasers may personally attend to the selection, fabrication, assembly and final detailing of their personal toy wands. Similarly, toy wand “kits” may also be selected, packaged and sold whereby purchasers can assemble and decorate their own toy wands in the convenience of their own home using the wand components, materials and decorative elements illustrated and described above. FIGS. 11A-11E illustrate various examples of toy wands that have been fabricated, assembled and detailed in a manner as described above.


In a further alternative embodiment, the RF/IR module 150 may be replaced (or complimented) with a laser or light emitting module for providing an alternative (or additional) mode of operation. This would have particular advantage where, for example, it is desired to provide directional control of a transmitted command signal such as may be useful for directional spell casting, target practice, or a shooting-gallery-style play effect.



FIG. 12 illustrates one possible embodiment of a light-activated interactive play system comprising a toy wand 100h configured with a light emitting module 215, an image preparation device 220, a display device 225, a camera 230, and a control system 235. The light emitting module 215 preferably emits a directional signal, such as, for example, visible or infrared light. The signal may be triggered by particular motions of the toy wand 100h, as described herein, or by other input provided by the user. Those skilled in the art will appreciate that movements of the toy wand 100h will cause corresponding movements of the signal emitted by the light emitting module 215, as illustrated in FIG. 12. The camera 230 preferably captures, detects and/or records the position of the signal emitted by the light emitting module 215 and communicates the captured image data to the control system 235. The control system 235 processes the image data by analyzing the position and/or movement of the light signal and then controls or triggers one or more effects based thereon.


For example, a user may move the toy wand 100h in a predetermined pattern to initiate a “magic spell.” The movement of the wand 100h causes a corresponding movement of the signal emitted by the light emitting module 215, which is captured by the camera 230. The control system 235 then processes the image data received from the camera 230 to determine which “spell” was cast and to cause or trigger the special effect(s) associated with that particular spell. For example, the control system 235 may cause the image preparation device 220 to modify the displayed image so that flowers appear to “magically” sprout from a hat 202. Another spell may cause an image of a wizard to magically appear within a crystal ball 203 (with optional sound and lighting effects), or a candle 206 to magically light.


In one embodiment the image preparation device 220 may comprise a video projector or an LCD projector, and the display device 225 may comprise a projection screen, a wall, or a translucent material upon which a projected image may be displayed. In another embodiment the image preparation device 220 may comprise a digital video source such as a memory, and the display device 225 may comprise a liquid crystal display (LCD) screen coupled to the digital video source. For example, the image preparation device 220 may be electrically coupled to the display device 225 through a wired or wireless transmission medium. In other embodiments, the image preparation device 220 may comprise multiple devices usable to project or to cause an image to appear on the display device 225.


The image preparation device 220 is preferably configured to cause at least one video image and/or still image to appear on the display device 225. A skilled artisan will recognize from the disclosure herein that a wide variety of objects, characters, and/or images may be displayed on the display device 225. For instance, these may include images of mythical creatures, such as a dragon or a unicorn; magical objects, such as a flying carpet; or fantasy characters, such as a wizard or an elf; and combinations of the same or the like.


In one embodiment the camera 230 may comprise a high-speed still camera or a specialized video camera. In one embodiment the camera 230 may be configured to record the signal emitted by the light emitting module 215 as it is intercepted or reflected by the display device 225. In another embodiment the camera 230 may be located within a substantially enclosed area, such as, for example, a room, and configured to detect the signal emitted by the light emitting module 215 within the room and/or directed at objects or effects within the room. Optionally, multiple cameras 230 may be used to record or capture image data from different angles. Optionally, optical or infrared sensors may be used in place of, or in combination with, the camera 230 to detect the position and/or movement of the signal emitted by the light emitting module 215.


In one embodiment, the control system 235 may comprise a general purpose or a special purpose processor. In other embodiments, the control system 235 may comprise an application-specific integrated circuit (ASIC) or one or more modules configured to execute on one or more processors. The control system 235 receives and processes the image data received from the camera 230 by analyzing the position and/or movement of the signal emitted by the light emitting module 215. Based on this analysis the control system 235 determines modifications to be made to subsequent images prepared by the image preparation device 220. Optionally, the control system 235 may communicate with a central system or database and/or other devices capable of causing play effects other than modifications to the image displayed on the display device 225.


While an interactive gaming toy comprising a toy wand is specifically contemplated and described herein in detail, those skilled in the art will readily appreciate that the teachings herein are not limited to toy wands, but may be carried out using any number or variety of other objects and toys for which it may be desirable to imbue special “magic” powers or other functionalities described herein. For example, the activation circuit described above may be implemented in a variety of other gaming and entertainment applications such as, for example, a wireless or hard-wired input device for a video game, computer game or home game console, an arcade or redemption challenge device, home-operated amusement device using simple bells and buzzers, or the like. Alternatively, some or all of the various circuitry and components described herein above may be externally implemented such that an interactive gaming toy may not be entirely self-contained, but may rely on certain external components and circuitry for some or all of its functionality. Alternatively, some or all of the various circuitry and components described herein can be implemented in a user-wearable format such that various interactive play effects and the like, as described herein, may be actuated through particular hand or arm motions. Other suitable interactive gaming toys may include, for example and without limitation, sporting items such as paddles, nunchucks, simulated fishing rods, bats, and various sporting balls; household items such as candles, candle sticks, brooms, feather dusters, and paint brushes; writing implements such as pens, pencils, and crayons; musical instruments such as flutes, recorders, and drum sticks; educational items such as books and diaries; wearable items such as tassels, gloves, coats, hats, shoes and clothing items; role-play toys such as dolls, action figures, and stuffed animals; jewelry items such as rings, bracelets necklaces, and trinkets; natural items such as sticks, flowers, rocks, and crystals; and simulated food items such as apples, oranges, bananas, carrots, and celery.


Adjunct Gaming Items


If desired, one or more adjunct gaming items may also be provided and utilized as part of an interactive role-playing game such as disclosed herein. These may be used instead of or as an adjunct to other interactive gaming toys described herein. For example, FIGS. 13A-13B illustrate one embodiment of an adjunct gaming item comprising an RFID-enabled character card. Each card 325a preferably comprises a paper, cardboard or plastic substrate having a front side 328 and a back side 330. The front side 328 of each card 325a may be imprinted with graphics, photos, or any other information as desired. In the particular embodiment illustrated, the front side 328 contains an image of a particular character 345 from the Pajama Sam computer game series representing, for example, a role-play character desired to be imagined by a play participant. In addition, the front side 328 may include any number of other designs or information pertinent to its use and application in the game. For example, the character's powers, skills and experience level may be indicated, along with any other special powers or traits the character 345 may possess.


The back side 330 of the card preferably contains the card electronics comprising an RFID tag 128 pre-programmed with the pertinent information for the particular person, character or object portrayed on the front side 328 of the card. Preferably, the tag 128 is passive (requires no batteries) and has a read range greater than about 1 cm. RFID tags having read ranges of between about 10 cm to about 100 cm are particularly preferred, although shorter or longer read ranges will also work. The particular tag illustrated is a 13.56 MHz RFID tag inlay which has a useful read/write range of about 25 cm. It is sold under the brand name Tag-It™ and is available from Texas Instruments, Inc. (http://www.tiris.com, Product No. RI-103-110A). The tag 128 may be “read/write” or “read only”, depending on its particular gaming application. Optionally, less expensive chipless tags (described in more detail later) may also be used. If desired, the tag 128 may be covered with an adhesive paper label 344 or, alternatively, the tag may be molded directly into a plastic sheet substrate from which the card is formed.


Those skilled in the art will readily appreciate from the disclosure herein that a variety of character cards and/or other gaming items having features and advantages as disclosed herein may be used to play a wide variety of unique and exciting games within an RFID-enabled play facility and/or using an RFID-enabled gaming device or game console. For example, such games may be carried out using a specially configured gaming device or, alternatively, using a conventional computer gaming platform, home game console, arcade game console, hand-held game device, internet gaming device or other gaming device that includes an RFID interface that is able to communicate with RFID tag 128. Advantageously, play participants can use character cards 325a and/or other RFID-enabled gaming items to transport information pertinent to a particular depicted person, character or object to a favorite computer action game, adventure game, interactive play facility or the like. For example, as illustrated in FIG. 13C, a suitably configured video game console and video game may be provided which reads the card information and recreates the appearance and/or traits of the particular depicted person, character or object within the game (for example, the “Pajama Sam” character 345).


If desired, the game console may be further configured to write information to the card in order to change or update certain characteristics or traits of the character, person or object depicted by the card 325a in accordance with a predetermined game play progression. For example, in the course of playing a typical Pajama Sam game, players must “find” certain objects or tools (for example, flash light 346, lunch box 347 and PajamaMan mask 348) that they will use to solve certain puzzles or tasks presented by the game. Players “pick up” these objects or tools by clicking their mouse on the desired object. The computer game software then keeps a record of which objects have been collected and displays those objects on the computer screen when requested by the player. This information can also advantageously be stored on the RFID tag 128 associated with the character card 325a so that in future game sessions the card information can be automatically read and the computer experience can be modified or updated in accordance with the new information recorded on the card 325a. In this manner, the character role-play experience becomes portable, personal and long-term. This, in turn, facilitates the development of even more sophisticated and complex role-play characters and longer, more enjoyable role play experiences as players are able to continue playing with and developing the same role-play character(s) over long periods of time and in different and varied play environments.



FIGS. 14A-14B are front and back views, respectively, of an alternative embodiment of an adjunct gaming item comprising an RFID-enabled trading card 325b. The particular trading card illustrated is provided in the theme of the Pikachu character from the popular Pokemon® card game, video game and TV series. FIGS. 14C-14D illustrate several other possible Pokemon® themed trading cards 325c, 325d comprising the characters Charizard (FIG. 14C) and Cubone (FIG. 14D). Cards 325b, 325c, 325d may be collected or traded and/or they may be used to play various games, such as a Pokemon® arena competition using an electronic interface capable of reading the card information.


Each trading card preferably comprises a paper, cardboard or plastic substrate having a front side 328 and a back side 330. The front side 328 may be imprinted with graphics, photos, or any other information as desired. For example, the front side 328 of card 325b includes an image of the Pikachu character along with printed information 349 describing, for example, the character's type, size and evolution in the game, and any special powers or traits the character may possess. The back side 330 contains an RFID tag 128 configured and arranged in the manner described above in connection with FIGS. 13A-13B.


RFID-enabled trading cards 325b, 325c, 325d and the virtual characters they represent, need not be static in the game, but may change over time according to a central story or tale that unfolds in real time (for example, through televised shows or movies released over the course of weeks, months or years). Thus, a trading card that may be desirable for game play this week (for example, for its special powers or abilities), may be less desirable next week if the underlying character is injured or captured in the most recent episode of the story. Another significant and surprising advantage of RFID-enabled trading cards is that multiple cards can be stacked and simultaneously read by a single RFID reader even where the cards are closely stacked on top of one another and even though the reader may be hidden from view. This feature and ability creates limitless additional opportunities for exciting game complexities, unique game designs and gaming strategies heretofore unknown.


Of course, those skilled in the art will readily appreciate from the disclosure herein that the underlying concept of an RFID-enabled character card or trading card is not limited to cards depicting fantasy characters or objects, but may be implemented in a wide variety of alternative embodiments, including conventional playing cards, poker cards, board game cards and tokens, sporting cards, educational cards and the like. If desired, any number of other suitable collectible/tradable tokens, coins, trinkets, simulated crystals or the like may also be provided and used with a similar RFID tag device for gaming or entertainment purposes in accordance with the teachings of the present invention.


For example, RFID tag devices may be included on “magic articles” that may be purchased or acquired in a gaming or interactive play system. For instance, a user may purchase an invisibility cloak, magic beads, belts, and the like during an interactive play experience. The RFID tags may be used to communicate to a central database that a certain player has purchased or is in possession of the tagged item. The central database may then track the tagged items and/or may cause those in possession of the tagged items to have increased “magical” skills or powers, such as additional protection from the spells “cast” by opposing players.


Toy/Game Interface


Those skilled in the art will appreciate that the various interactive gaming toys and gaming items described herein may be used with a specially configured computer, video game, home game console, hand-held gaming device, game controller or similar gaming device having a compatible wireless interface configured to communicate with each interactive gaming toy or gaming item in the manner disclosed herein. Alternatively, a conventional gaming device may be used in conjunction with a peripheral device that provides the compatible wireless interface. For example, this may comprise an RFID reader or an RFID reader/writer device such as described herein.


One embodiment of a peripheral gaming device in accordance with the present invention is illustrated in FIG. 15A. The peripheral gaming device 301a basically comprises a themed toy having an integrated RFID reader/writer 300 configured to communicate with one or more RFID-tagged toys or gaming items in a manner disclosed herein. If desired, the peripheral gaming device 301a may be configured in accordance with any desired theme, such as may be consistent with a game played using one or more associated gaming toys or gaming items, or may be configured in a generic style. In the particular example illustrated, the peripheral gaming device 301a takes on the form of a magical portal 303 guarded by a pair of fearsome dragons 307a, 307b. The dragons 307a, 307b and magical portal 303 are preferably integrally molded and configured such that the portal 303 is supported in a substantially vertical upright position when the peripheral gaming device 301a is placed on a flat support surface (for example, a table or floor surface). The portal 303 defines an opening 309 that is preferably sized and configured to allow one or more RFID-tagged interactive gaming toys or gaming items to enter and pass through. An RF antenna 306, which is electrically coupled to RFID reader/writer 300, is preferably hidden within the portal 303 and substantially surrounds the opening 309, as illustrated.


Those skilled in the art will appreciate that as an RFID-tagged gaming toy or gaming item enters and passes through the opening 309 it may be wirelessly powered by an electromagnetic field generated by the antenna 306, such as disclosed and described herein in connection with FIG. 8A. The antenna 306 and RFID reader/writer 300 may also provide a wireless communication interface for communicating with the RFID-tagged gaming toys and gaming items as they enter and pass through the opening 309. RFID reader/writer 300 may also be configured to communicate with a host computer 375 (for example, a home computer, home game console, hand-held game unit) using, for example, one or more industry standard communication interfaces such as RS232, Ethernet, or a wireless network.


If desired, the peripheral gaming device 301a may also include the ability to produce light, vibration or sound effects to complement the operation of an associated interactive gaming toy. For example, these effects may be triggered based on information wirelessly communicated by an RFID-tagged gaming toy to the RFID reader/writer 300. Optionally, the opening 309 may open into an enclosed space, such as a simulated vault, cave or secret chamber. For example, the enclosed space may be configured to accommodate one or more interactive gaming toys. In one embodiment, the portal opening 309 is configured such that gaming toys can only enter or exit an enclosed space by passing through the portal 303. In this manner, one or more associated interactive gaming toys may be wirelessly tracked as they enter or exit an enclosed space through opening 309.



FIG. 15B illustrates an alternative embodiment of a peripheral gaming device 301b having an integrated RFID reader/writer 300 configured to communicate with one or more RFID-tagged toys or gaming items in a manner disclosed herein. In the particular example illustrated, the peripheral gaming device 301b takes on the form of a magician's hat. The brim of the hat defines an opening 309 that is preferably sized and configured to allow one or more RFID-tagged interactive gaming toys or gaming items to enter and pass through. An RF antenna 306, which is electrically coupled to RFID reader/writer 300, is preferably hidden within the brim of the hat and substantially surrounds the opening 309, as illustrated. The opening 309 preferably lies in a horizontal plane, as illustrated, and opens into a substantially enclosed space below the brim comprising, for example, the crown of the hat. This space is preferably sized and configured to accommodate one or more RFID-tagged interactive gaming toys or gaming items such as disclosed and described herein. In one embodiment, the peripheral gaming device 301b is configured such that gaming toys can only enter or exit the enclosed space by passing through the opening 309. In this manner one or more associated interactive gaming toys may be wirelessly tracked as they enter or exit the enclosed space through opening 309. If desired, a false bottom and/or one or more hidden compartments (not shown) may be provided within the enclosed space and configured to selectively conceal one or more gaming items.


Those skilled in the art will appreciate that as an RFID-tagged gaming toy or gaming item approaches the opening 309 (either from above or below) it may be wirelessly powered by an electromagnetic field generated by the antenna 306, such as disclosed and described herein in connection with FIG. 8A. The antenna 306 and RFID reader/writer 300 also provides short-range two-way wireless communications with each RFID-tagged gaming toy over a limited wireless communication range preferably greater than about 1 cm and less than about 60 cm. This communication range preferably extends both above and below antenna 306 such that the peripheral gaming device 301b is able to wirelessly power and communicate with RFID-tagged items as they approach, enter and pass through the opening 309. If desired, this communication range may be the same as, greater than, or less than, the distance from antenna 306 to a lower support surface 311 upon which RFID-tagged items (for example, a toy rabbit or a gnome doll) may be placed. For example, the limited communication range may be sufficient or insufficient to wirelessly power and communicate with the RFID-tagged items placed on the lower support surface 311. If desired, one or more auxiliary antennae (not shown) may be provided and electrically coupled to RFID reader/writer 300 in order to extend the communication range of the RFID reader/writer 300 and/or to provide additional electromagnetic field energy for wirelessly powering RFID-tagged gaming items. For example, a second antenna (not shown) may be provided within the lower support surface 311.


RFID reader/writer 300 is also preferably configured to communicate with a host computer 375 (for example, a home computer, home game console, hand-held game unit) using, for example, one or more industry standard communication interfaces such as RS232, Ethernet, or a wireless network. If desired, the peripheral gaming device 301b may also include the ability to produce light, vibration or sound effects to complement the operation of an associated interactive gaming toy. For example, various effects may be triggered when an RFID-enabled toy wand is brought within wireless communication range of the peripheral gaming device 301b.



FIG. 15C illustrates a further alternative embodiment of a peripheral gaming device 301c having an integrated RFID reader/writer 300 configured to communicate with one or more RFID-tagged toys or gaming items in a manner disclosed herein. In the particular example illustrated, the peripheral gaming device 301c takes on the form of a witch's cauldron. The rim of the cauldron defines an opening 309 that is preferably sized and configured to allow one or more RFID-tagged gaming items (for example, a spider, a batwing, and a vial of potion) to enter and pass through. An RF antenna 306, which is electrically coupled to RFID reader/writer 300, is preferably hidden within the rim of the cauldron and substantially surrounds the opening 309, as illustrated.


The opening 309 preferably lies in a horizontal plane, as illustrated, and opens into a substantially enclosed space below the rim comprising the belly of the cauldron. This space is preferably sized and configured to accommodate one or more RFID-tagged interactive gaming toys or gaming items such as disclosed and described herein. Those skilled in the art will appreciate that as an RFID-tagged gaming toy or gaming item approaches the opening 309 (either from above or below) it may be wirelessly powered by an electromagnetic field generated by the antenna 306, such as disclosed and described herein in connection with FIG. 8A. The antenna 306 and RFID reader/writer 300 also provides short-range two-way wireless communications with each RFID-tagged gaming toy over a limited wireless communication range preferably greater than about 1 cm and less than about 60 cm. The communication range preferably extends both above and below antenna 306 such that the peripheral gaming device 301c is able to wirelessly power and communicate with RFID-tagged items as they approach, enter and pass through the opening 309. Optionally, the communication range is sufficient to wirelessly power and communicate with multiple gaming toys or gaming items that may be placed in the belly of the cauldron as part of an interactive game.


RFID reader/writer 300 is also preferably configured to communicate with a host computer 375 (for example, a home computer, home game console, hand-held game unit) using, for example, one or more industry standard communication interfaces such as RS232, Ethernet, or a wireless network. If desired, the peripheral gaming device 301c may also include the ability to produce light, vibration or sound effects to complement the operation of an associated interactive gaming toy or computer-animated game. For example, various special effects (for example, boiling, sparking, gurgling, shaking, or popping), may be triggered as each RFID-tagged gaming item is dropped into the cauldron. These effects may be different for each RFID-tagged item (or combination of items) based on information wirelessly communicated by each RFID-tagged item to the RFID reader/writer 300.


In addition to the embodiments described above and illustrated in FIGS. 15A, 15B, and 15C, in some embodiments an antenna 306 may be configured into a variety of shapes and sizes to fit any desired theme. For example, in some embodiments, the antenna 306 may substantially surround an opening shaped like a knot on a real or artificial tree or an opening on a house, such as a window or a door. In some embodiments an antenna 306 as described above may be configured to substantially surround an opening in a desk drawer, a shelf, a cup, a mug, a door to a room, or any other opening 309. In some embodiments, the antenna 306 may substantially surround a portion of a tunnel, such that RFID reader/writer 300 may provide a wireless communication interface for communicating with the RFID-tagged gaming toys and gaming items as they enter and pass through the tunnel. In some embodiments, a tunnel may have multiple antennae 306, which enable one or more RFID reader/writers 300 to track the progress of RFID-tagged gaming toys and gaming items as they enter and pass through the tunnel.


RFID Tags and Readers


Many of the preferred embodiments of the invention illustrated and described herein are RFID-enabled—that is, they utilize RFID technology to electrically store and communicate certain relevant information (for example, UPIN and UGIN, game levels, points, combinations of the same or the like) and/or to wirelessly actuate or control various play effects. RFID technology provides a universal and wireless medium for uniquely identifying objects and/or people and for wirelessly exchanging information over short and medium range distances (10 cm to 10 meters). Commercially available RFID technologies include electronic devices called transponders or tags, and reader/writer electronics that provide an interface for communicating with the tags. Most RFID systems communicate via radio signals that carry data either uni-directionally (read only) or, more preferably, bi-directionally (read/write).


Several examples of RFID tags or transponders particularly suitable for use with the present invention have been illustrated and described herein. For example, in some of the embodiments illustrated and described above, a 134.2 kHz/123.2 kHz, 23 mm glass transponder 118 is selected, such as available from Texas Instruments, Inc. (http://www.tiris.com, for example, Product No. RI-TRP-WRHP). As illustrated in more detail in FIG. 16A, this transponder basically comprises a passive (batteryless) RF transmitter/receiver chip 240 and an antenna 245 provided within an hermetically sealed vial 243. If desired, the RFID transponder 118 may include an optional external interrupt/disable line 260, such as illustrated in FIG. 16A.



FIG. 16B is a simplified schematic diagram of one embodiment of an RFID reader/writer 300 for use with the RFID transponder 118 of FIG. 16A. A preferred reader/writer device is the Series 2000 Micro Reader available from Texas Instruments, Inc. (http://www.tiris.com, for example, Product No. RI-STU-MRD1). As illustrated, the reader/writer 300 basically comprises an RF Module 302, a Control Unit 304 and an antenna 306. When the transponder 118 comes within a predetermined range of antenna 306 (about 20-200 cm) the transponder antenna 245 (FIG. 16A) is excited by the radiated RF fields 308 and momentarily creates a corresponding voltage signal which powers RF transmitter/receiver chip 240. In turn, the RF transmitter/receiver chip 240 outputs an electrical signal response which causes transponder antenna 245 to broadcast certain information stored within the transponder 118 comprising, for example, 80 to 1000 bits of information stored in its internal memory. This information preferably includes a unique identifier such as a user ID (for example, UPIN/UGIN) and/or certain other items of information pertinent to the user, the associated toy or gaming item, and/or the game or play experience.


A carrier signal embodying this information is received by antenna 306 of RFID reader/writer 300. RF Module 302 decodes the received signal and provides the decoded information to Control Unit 304. Control Unit 304 processes the information and provides it to an associated logic controller, PID controller, computer or the like using a variety of standard electrical interfaces (not shown). Thus, the information transmitted by transponder 118 and received by reader/writer 300 may be used to control one or more associated play effects through a programmable logic controller, for example. In one embodiment, for example, the information transmitted includes data relating to the activation of the sensors 122, 124 of the toy wand 100g (FIG. 8A). In other embodiments, the transmitted information may include timing information, such as the duration of time that a sensor is activated and/or the duration of time between successive activations of the sensors 122, 124. Play effects, may include, for example, lighting effects, sound effects, various mechanical or pneumatic actuators and the like.


Preferably, RFID reader/writer 300 is also configured to broadcast or “write” certain information back to the transponder 118 to change or update information stored in its internal memory, for example. The exchange of communications occurs very rapidly (about 70 ms) and so, from the user's perspective, it appears to be virtually instantaneous. Thus, the transponder 118 may be used to wirelessly actuate and/or communicate with various associated effects by simply touching or bringing the transponder 118 into relatively close proximity (for example, 2-3 cm) with the antenna 306 of a reader/writer unit 300.



FIG. 16C is a simplified circuit schematic of the reader/writer unit 300 of FIG. 16B. The read or write cycle begins with a charge (or powering phase) lasting typically 15-50 ms. During this phase, the RF Module 302 causes the antenna 306 to emit an electromagnetic field at a frequency of about 134.2 kHz. The antenna circuit is mainly formed by the resonance capacitor C1 and the antenna coil 306. A counterpart resonant circuit of the transponder 118 is thereby energized and the induced voltage is rectified by the integrated circuit 240 and stored temporarily using a small internal capacitor (not shown).


The charge phase is followed directly by the read phase (read mode). Thus, when the transponder 118 detects the end of the charge burst, it begins transmitting its data using Frequency Shift Keying (FSK) and utilizing the energy stored in the capacitor. The typical data low bit frequency is 134.2 kHz and the typical data high bit frequency is 123.2 kHz. The low and high bits have different duration, because each bit takes 16 RF cycles to transmit. The high bit has a typical duration of 130 μs, the low bit of 119 μs. Regardless of the number of low and high bits, the transponder response duration is generally less than about 20 ms.


The carrier signal embodying the transmitted information is received by antenna 306 and is decoded by RF module 302. RF Module 302 comprises integrated circuitry 312 that provides the interface between the transponder 118 and the Control Module 304 (data processing unit) of the Reader/Writer Unit 300. It has the primary function and capability to charge up the transponder 118, to receive the transponder response signal and to demodulate it for further digital data processing. A Control Unit 304, comprising microprocessor 314, power supply 316 and RS232 Driver 318, handles most data protocol items and the detailed fast timing functions of the Reader/Writer Module 300. It may also operate as an interface for a PC, logic controller or PLC controller for handling display and command input/output functions, for example, for operating/actuating various associated play effects. If desired, the Reader/Writer Module 300 may also be configured to communicate with an optional Host Computer 375 through one or more standard communication interfaces, such as RS232, RS422 or RS485.


In other embodiments illustrated and described above, an adhesive-backed RFID tag inlay is utilized, such as the 13.56 MHz tag sold under the brand name Tag-It™ available from Texas Instruments, Inc. (http://www.tiris.com, Product No. RI-103-110A). These tags have a useful read/write range of about 25 cm and contain 256 bits of on-board memory arranged in 8×32-bit blocks which may be programmed (written) and read by a suitably configured read/write device. The Tag-It™ 13.56 MHz RFID tag has particular advantages in the context of the present invention. Paper thin and batteryless, this general purpose read/write transponder is placed on a polymer tape substrate and delivered in reels. It fits between layers of laminated paper or plastic to create inexpensive stickers, labels, tickets and badges that may be easily secured or applied to virtually any play object, toy wand, wristband, badge, card or the like, for electronically storing and retrieving desired user-specific or object-specific information. Such information may include, for example, UPIN, UGIN, object type/size/shape/color, first and/or last name, age, rank or level, total points accumulated, tasks completed, facilities visited, and combinations of the same or the like. These or similar RFID tags may be applied to any of the interactive gaming toys disclosed and described herein or to any other toys, play objects, jewelry, trinkets, action figures, collectibles, trading cards and generally any other items desired to be incorporated as part of an RFID-enabled gaming experience.


As illustrated in more detail in FIG. 17A, RFID tag 128 generally comprises a spiral wound antenna 338, a radio frequency transmitter chip 340 and various electrical leads and terminals 342 connecting the chip 340 to the antenna 338. The tag 128 is configured to be initially activated by a radio frequency signal broadcast by an antenna 306 of an adjacent reader or activation device 300 (See FIGS. 17B, 17C). The signal impresses a voltage upon the tag antenna 338 by inductive coupling which is then used to power the chip 340. When activated, the chip 340 transmits via radio frequency a unique identification number preferably corresponding to the UPIN and/or UGIN described above. The signal may be transmitted either by inductive coupling or, more preferably, by propagation coupling over a distance “d” determined by the range of the tag/reader combination (See FIG. 17C). This signal is then received and processed by the associated reader 300 as described above. If desired, the RFID tag 128 may also be configured for read/write communications with an associated reader/writer. Thus, the UPIN or UGIN can be changed or other information may be added.


As indicated above, communication of data between a tag and a reader is by wireless communication. As a result, transmitting such data is always subject to the vagaries and influences of the media or channels through which the data has to pass, including the air interface. Noise, interference and distortion are the primary sources of data corruption that may arise. Thus, those skilled in the art will recognize that a certain degree of care should be taken in the placement and orientation of readers 300 so as to minimize the probability of such data transmission errors. Preferably, the readers are placed at least 30-60 cm away from any metal objects, power lines or other potential interference sources. Those skilled in the art will also recognize that the write range of the tag/reader combination is typically somewhat less (˜10-15% less) than the read range “d” and, thus, this should also be taken into account in determining optimal placement and positioning of each reader device 300. Preferably a tag/reader combination is selected having a read/write range greater than about 1 cm. If a longer read/write range and/or more memory is desired, optional battery-powered tags may be used instead, such as available from Axcess, Inc. and/or various other vendors known to those skilled in the art.



FIG. 17D is a simplified block diagram illustrating the basic organization and function of the electronic circuitry comprising the radio frequency transmitter chip 340 of the RFID tag device 128 of FIG. 17A. The chip 340 basically comprises a central processor 530, Analogue Circuitry 535, Digital Circuitry 540 and on-board memory 545. On-board memory 545 is divided into read-only memory (ROM) 550, random access memory (RAM) 555 and non-volatile programmable memory 560, which is available for data storage. The ROM-based memory 550 is used to accommodate security data and the tag operating system instructions which, in conjunction with the processor 530 and processing logic deals with the internal “house-keeping” functions such as response delay timing, data flow control and power supply switching. The RAM-based memory 555 is used to facilitate temporary data storage during transponder interrogation and response. The non-volatile programmable memory 560 may take various forms, electrically erasable programmable read only memory (EEPROM) being typical. It is used to store the transponder data and is preferably non-volatile to ensure that the data is retained when the device is in its quiescent or power-saving “sleep” state.


Various data buffers or further memory components (not shown), may be provided to temporarily hold incoming data following demodulation and outgoing data for modulation and interface with the transponder antenna 338. Analog Circuitry 535 provides the facility to direct and accommodate the interrogation field energy for powering purposes in passive transponders and triggering of the transponder response. Analog Circuitry 535 also provides the facility to accept the programming or “write” data modulated signal and to perform the necessary demodulation and data transfer processes. Digital Circuitry 540 provides certain control logic, security logic and internal microprocessor logic required to operate central processor 530.


Of course, those skilled in the art will readily appreciate from the disclosure herein that the invention is not limited to the specific RFID transponder devices disclosed herein, but may be implemented using any one or more of a wide variety of commercially available wireless communication devices such as are known or will be obvious from the disclosure herein to those skilled in the art. These include, without limitation, RFID tags, EAS tags, electronic surveillance transmitters, electronic tracking beacons, Wi-Fi, GPS, bar coding, and the like.


Another RFID tagging technology of particular interest for purposes of practicing the present invention are the so-called “chipless” RFID tags. These are extremely low-cost RFID tags that are available in the form of a printed circuit on a thin, flat adhesive-backed substrate or foil. These tags are similar in size, shape and performance to the Tag-It™ RFID inlay tags described above, except that these tags require no on-board integrated circuit chip. Chipless RFID tags can be electronically interrogated to reveal a pre-encoded unique ID and/or other data stored on the tag. Because the tags do not contain a microchip, they cost much less than conventional RFID tags. An adhesive-backed chipless RFID tag with up to 10 meters range and 256 bits of data, can cost one tenth of their silicon chip equivalents and typically have a greater physical performance and durability. For example, a suitable chipless RFID tag is being made available from Checkpoint Systems under its ExpressTrak™ brand. Very inexpensive chipless RFID tags (and/or other types of RFID tags) may also be directly printed on paper or foil substrates using various conductive inks and the like, such as are available from Parelec Inc. under its Parmod VLT™ brand.


Wireless Receivers/Transmitters


In many of the preferred embodiments of the invention illustrated and described herein it is disclosed to use a radio frequency (RF) and/or infrared (IR) transmitter to send wireless signals over relatively long range distances (for example, 10-100 meters or more). For example, the toy wand 100g illustrated and described in connection with FIG. 8A includes an internal RF/IR Module 150 for communicating various command signals to one or more remote RF/IR receivers and associated effects. RF/IR Module 150 can comprise any number of small, inexpensive RF transmitters such as are commercially available from Axcess, Inc., of Dallas, Tex. If directionality is desired, any number of small, inexpensive infrared (IR) LED transmitters may be used, such as the type commonly employed in television remote controls, keyless entry systems and the like.



FIG. 18A is a schematic block diagram of one embodiment of a transmitter module 150 adapted for use in accordance with the present invention. The transmitter module 150 generally comprises an RF or IR transmitter 358 driven and controlled by a microprocessor or ASIC 350. ASIC 350 includes address storage module 352, data storage module 354 and shift register 356. Address storage module 352 includes a stored address or coded value, for example, in parallel bit format, that is a preselected coded value that may be uniquely associated with a particular transmitter module 150. Address storage module 352 applies the address coded value to an encoder, such as shift register 356 which, when enabled, encodes the coded value by converting it from parallel bit format to serial bit format which is applied to RF/IR transmitter 358. Similarly, data storage module 354 may include coded data or commands provided by a user (for example, via any of the various command input circuits and structures described above in connection with FIGS. 8A-8B). Data storage module 354 applies the coded data values to shift register 356 which, when enabled, encodes the coded data by converting it from parallel bit format to serial bit format which is also applied to RF/IR transmitter 358. Transmitter 358 modulates the coded address and data values and encodes it in serial bit format onto either a radio frequency or infrared carrier signal which is transmitted as an output signal (RF/IROut). The output signal may be transmitted, for example, via a simple loop antenna (for RF signals) or an infrared LED (for IR signals). If desired, application of electrical power from an internal battery source 152 (or other power sources described herein) may be controlled via activation circuitry 120 such as illustrated and described above in connection with FIGS. 5 and 8A-8B.


Those skilled in the art will recognize from the disclosure herein that transmitter module 150 may be implemented in a variety of known electrical technologies, such as discrete electronic circuits and/or integrated circuits Preferably, integrated circuitry technology and/or surface mount components are used to reduce the physical size of the circuit 150 such that it is able to fit within a relatively small space such as an internal cavity of an interactive gaming toy.



FIG. 18B is a schematic block diagram of one embodiment of a receiver module 362 which is configured to operate in conjunction with transmitter module 150 previously described. Radio frequency or infrared command signals transmitted by transmitter module 150 are provided as input signals (RF/IRIn) to RF/IR receiver 363. RF/IR receiver 363 may comprise, for example, a simple tuned circuit with loop antenna (for receiving RF signals) or one or more infrared sensors (for receiving IR signals). Command signals received by RF/IR receiver 363 are applied to a decoder, such as shift register 364 which converts the coded value therein from a serial bit format to a parallel bit format. Address comparator 366 receives at one input the transmitter module coded address value in parallel bit format from shift register 364 and at its other input a preselected fixed or dynamically stored coded value from address storage 368. The preselected coded value from address storage 368 corresponds to the preselected coded value of the transmitter module 150 with which receiver module 362 is associated or compatible. In other words, the preselected coded value stored in transmitter address storage 352 of transmitter module 150 is the same as or compatible with a preselected coded value as is stored in address storage 368 of receiver module 362 with which it is associated or compatible. If the coded address value in the received command signal matches all or a predetermined portion of the preselected fixed or dynamic coded value stored in address storage 368, this coincidence is detected by address comparator 366 and is applied to restart or reset receive timer 372. Receive timer 372 preferably has a time-out period of, for example, 0.5-3 seconds and, if it is not restarted or reset within this time period, it produces a command termination signal which tells an associated controller 374 to process the received command signals(s) and to actuate one or more corresponding play effects such as lighting effects 376, sound effects 377 and various actuator-driven effects, such as opening of a treasure chest 378. Each of the functional elements of receiver module 362 and controller 374 receive electrical power from a suitable power source 380, as illustrated.


In operation, the RF/IR transmitter module 150 transmits a certain command signal (RF/IROut) including coded address and optional coded data information. This signal is received and decoded by receiver module 362 as input signal (RF/IRin). The decoded transmitter address information is compared to a fixed or dynamically stored coded value from address storage 368. Preferably, an immediate effect such as a pulsing light or sound is actuated by controller 374 in order to provide visual and/or aural cues that a command signal was received. Receive timer 372 is initiated and the RF receiver module 362 awaits the next command signal. If no further signal is received before the timer 372 times out, then the command signal is assumed to be complete and the controller 374 is instructed to process the received command signal(s) and actuate one or more relays, for example, thereby triggering whatever appropriate effect(s) correspond to the command signal received.


For applications supporting multiple wireless input devices (i.e., multiple RF/IR transmitter modules 150) within a single play space, the address comparator 366 of receiver module 362 is preferably configured to accept either: (1) a range of valid “compatible” addresses from the set of RF/IR transmitter modules 150; or (2) any valid address from a list of valid addresses stored in address storage module 368. In the first case, each transmitter module 150 within a defined group of transmitter modules (for example, all Level-1 toy wands) would preferably be configured to have a coded address value having a portion of address bits that are identical and a portion of address bits that may be unique. The receiver module 362, upon detecting a compatible address bit sequence, decodes the data bits thereof and sets a latch selected by those particular data bits. A number of such latches, may be provided, for example, for recognizing and distinguishing further such command signals originating from multiple users and/or wands. In the second case, the receiver module 362 stores a list of specific coded values, i.e. valid addresses, in a memory, such as memory 368, and as transmitted addresses are received, they are compared to the valid addresses in this list. Thus, only signals transmitted by RF/IR transmitter modules that are on the list of valid addresses are accepted by receiver module 362. In this manner, for example, command signals sent by Level-1 toy wands can be distinguished from command signals sent by Level-2 toy wands.



FIG. 18C is a schematic block diagram of a portion of a receiver module 362 including an embodiment of address comparator 366 and of address storage 368 particularly suited for operating with a plurality of simultaneously operating transmitter modules 150. For purposes of illustration, blocks in FIG. 18C that are the same as blocks in FIG. 18B described above are shown in phantom and are identified by the same numeric designation. Address storage 368 includes addressable registers or memory 386 in which are stored the preselected coded identification values corresponding to the preselected coded identification value of each of a plurality of compatible transmitter modules 150 desired to be operably associated with receiver 362. Address selector 388 repetitively generates a sequence of addresses including the addresses of all the registers of addressable register 386 within a relatively short time period less than about 50-100 milliseconds. Thus the complete set of preselected stored coded values are applied to one input of coded value comparator 390. The received coded identification value received and decoded at the output of shift register 364 is applied to the other input of coded value comparator 390, whereby the received coded identification value is compared to each one of the coded values stored in addressable register 386.


Address comparator 366 preferably includes a latch circuit 392 having an addressable latch corresponding to each register in addressable register 386 and that is addressed by the same address value generated by address selector 388 to address register 386. Coded value comparator 390 determines when there is a match between the received coded value and the stored coded value. The occurrence of a match causes comparator 390 to set the corresponding latch in latch circuit 392. If received coded identification values corresponding to all of the stored fixed coded values are received and properly decoded, then all of the latches in latch circuit 392 will be set, thereby making a “true” condition at the inputs of AND gate 394 and causing its output to become “true.” This “true” signal from AND gate 394 resets receive timer 372, as described above in connection with FIG. 18B, and also activates a reset circuit 396 to reset all the latches of latch circuit 392 so that the comparison sequence of received coded identification values to the set of stored fixed coded values begins again. If all of the preselected received coded values are not received, then all of the latches in latch circuit 392 are not set, the output of AND gate 394 does not become “true”, and receive timer 372 times out and issues the command termination signal discussed above. Although the receiver module 362 of FIG. 18C is disclosed with reference to particular embodiments, a skilled artisan will recognize from the disclosure herein that a wide variety of alternative structures may be used.



FIG. 19 is a detailed electrical schematic diagram of an exemplary embodiment of transmitter module 150 illustrated and discussed above. Electrical power is provided by one or more batteries 152 and/or other power sources as illustrated and described herein. This power is preferably switched by activation circuit 120 and/or optional timer module 402. Electrical power is provided via diode D2 to the transmit timer U1, such as an integrated circuit one-shot multivibrator type LM555 available from National Semiconductor Corporation. The time-out interval of multivibrator U1 is established by resistors R2, R3 and capacitor C1 which need not be high precision components. When activation circuit 120 is activated, a voltage is applied through resister R1 to the gate of a transistor Q1. This causes electrical power to be applied from battery 152 to a five-volt voltage regulator U4 such as a type LM78L05 also available from National Semiconductor Corporation. Alternatively, the periodic output from U1 may be applied to the gate of a transistor Q1 to the same effect (for example, for sending periodic “beacon” transmissions).


Regulated voltage from regulator U4 is applied to shift register 356 (pin 18) and RF transmitter 358. Shift register 356 is implemented by an encoder integrated circuit U2 such as a 212 series encoder type HT12E available from Holtek Microelectronics in Hsinchu, Taiwan, R.O.C. Non-volatile address storage 352 is implemented by twelve single pole switches in switch packages SW1 and SW2 which are set to produce a twelve-bit coded value which is applied in parallel bit format to encoder integrated circuit U2 of shift register 356. Once set by the manufacturer or the user, the preselected coded value stored in address storage 352 is fixed and will not change absent human intervention. However, in alternative embodiments SW2 may be replaced in whole or in part by command selection circuitry such as touch switches, tilt switches and the like illustrated and described above in connection with FIG. 8A. Such circuitry enables users to actively select and change the coded data impressed upon address lines 8-10 of encoder integrated circuit U2. Integrated circuit U2 reproduces the coded address and data values in pulse-width modulated serial-bit format and applies it through diode D1 to RF transmitter 358 (which, in alternative embodiments, may comprise an IR transmitter). RF transmitter 358 includes a class B biased transistor Q2 in an L-C tuned RF oscillator transmitter coupled to a loop antenna 406 for transmitting the command signal coded values (address bits coded by SW1 and data bits coded by SW2) produced by encoder U2.


Transmitter module 150 need only employ a small antenna such as a small loop antenna and is not required to have optimum antenna coupling. In a typical embodiment, with a transmitter frequency of about 915 MHz, a transmitter peak power output of less than or equal to one milliwatt produces a transmission range R of about 20-30 meters. Other frequencies and power levels may also be employed. The low transmitter power is particularly advantageous in that it allows the size of transmitter module 150 to be made very small.



FIG. 20 is an electrical schematic diagram of an exemplary embodiment of receiver module 362 illustrated and discussed above. Power is supplied by a voltage source 410 which can be either a battery or a DC power supply. Voltage from voltage source 410 is regulated by voltage regulator circuit U3 such as type LM78L05 to produce a regulated+5 volt power supply for the functional blocks of receiver module 362. In operation, command signals transmitted from transmitter modules are received at loop antenna 412 and applied to RF receiver 363 (which, in alternative embodiments, may comprise an IR receiver) including a receiver sub-circuit integrated circuit U8 such as type RX-2010 available from RF Monolithics in Dallas, Tex. The identification signal, including the twelve bit coded value in serial-bit format is coupled from the output of receiver sub-circuit U8 to shift register decoder and address comparator 364/366 which are implemented in an integrated circuit U5, such as a 212 series decoder type HT12D also available from Holtek Microelectronics. Decoder U5 converts the coded value in serial-bit format to parallel-bit format and compares that received coded value to the preselected stored coded fixed reference value in parallel bit format determined, for example, by the positions of the twelve single pole switches in switch packages SW3, SW4 of address storage module 368.


Receive timer 372 is implemented by one-shot timer integrated circuit U6a such as type 74123N and D-flip flop U7a such as type 74HC74D, both of which are available from National Semiconductor Corporation of Santa Clara, Calif. When comparator 366 detects a match between the received coded value from transmitter module 150 and the coded value stored in address storage 368 it resets one-shot timer U6a. If one-shot timer U6a is not again reset within the time determined by timing resistor R8 and timing capacitor C9, U6a then sets flip-flop U7a and its Q output becomes low thereby applying a voltage input to controller 374 signifying the end of a transmitted command signal. Controller 374 then processes the received command signal or signals (for example, stored in a stack register) and appropriately operates one or more associated play effects 376.


Those skilled in the art will appreciate that the switch positions of the twelve switches SW1, SW2 of transmitter module 150 correspond to the switch positions of the corresponding twelve switches SW3, SW4 of receiver module 362. These preset values may be fixed or dynamic, as discussed above. The twelve-bits available for storing coded values may be apportioned in a convenient way, for example, into an address portion and into a data portion. For example, the twelve-bit coded value can be apportioned into a ten-bit address portion (1024 possible combinations) and a two-bit data portion, which would accommodate up to four different transmitter command signals. If desired, the ten-bit address portion can be further divided into various logical portions representing, for example, designated wand levels (for example, 1, 2, 3 or 4), special acquired magic powers or skills, experience levels and the like. This coded data would preferably be shared and coordinated between all transmitter modules 150 and receiver modules 362 such that each associated gaming toy effectively would have its own unique powers and abilities as represented and identified by the coded address data. Thus, certain receivers and associated play effects would not respond to certain transmitter modules unless the address coding of the transmitter module is coded with the appropriate matching data. Persons skilled in the art will recognize also that recoding of transmitter modules is a convenient way to provide for advancement of game participants within an interactive gaming experience. For example, this can be accomplished manually (for example, by flipping dip switches SW1/SW2) or automatically/wirelessly (for example, via RF programmable code latching circuitry, not shown).


While the foregoing embodiments have been described in terms of a radio frequency (RF) or infrared (IR) transmission between a transmitter module 150 and receiver module 362, various alternative embodiments could also readily be implemented such as, for example, complimenting an RF transmitter and receiver set with an appropriately selected infrared (IR) transmitter and receiver set or a laser or light system. The IR or laser system would have particular advantage where, for example, it is desired to provide directional control of a transmitted command signal.


RF Transceivers (SRRF)


In certain embodiments, an interactive gaming toy may include an RF transceiver (a combination radio transmitter and receiver) configured to electronically send and receive information to and from various other compatible RF transceivers that may be provided within a play environment. The capability to provide two-way wireless communications (sometimes referred to herein as a send receive radio frequency communication protocol or “SRRF”) provide the basic foundation for a complex, interactive entertainment system. In its most refined embodiments, a user may electronically send and receive information to and from other SRRF-compatible interactive gaming toys and/or to and from a SRRF-compatible master control system (described in more detail later) located within and/or associated with any of a number of play environments


SRRF may generally be described as an RF-based communications technology and protocol that allows pertinent information and messages to be sent and received to and from two or more SRRF-compatible devices or systems. While the specific embodiments described herein are specific to RF-based communication systems, those skilled in the art will readily appreciate that the broader interactive play concepts taught herein may also be realized using any number of commercially available 2-way and/or 1-way medium range wireless communication devices and communication protocols such as, without limitation, infrared-, digital-, analog-, AM/FM-, laser-, visual-, audio-, and/or ultrasonic-based systems, as desired or expedient.


The SRRF system can preferably send and receive signals (up to 40 feet) between portable tokens (described in more detail below) and fixed transceivers. The SRRF system is also preferably able to associate a token with a particular zone as defined by a token activation area approximately 10-15 feet in diameter. Suitable embodiments of the SRRF technology described herein may be obtained from a number of suitable sources, such as AXCESS, Inc. and, in particular, the AXCESS active RFID network system for asset and people tacking applications.


In one embodiment, an entire entertainment facility may be configured with SRRF technology to provide a master control system for an interactive entertainment play environment using SRRF-compatible interactive gaming toys such as toy wands and/or other SRRF-compatible gaming devices. A typical entertainment facility provided with SRRF technology may allow 300-400 or more users to more-or-less simultaneously send and receive electronic transmissions to and from a master control system using a toy wand, for example, or other SRRF-compatible gaming device.


For example, a master control system may comprise a software program, a centralized computer network and an associated data-base that monitors the operation of each interactive gaming toy within a particular location. This information is then used to adjust the play experience for each user based on “knowing” where the user/player has been, what objectives that player has accomplished and how many points or levels have been reached. The system can then send messages to the user throughout the play experience. For example, the system can allow or deny access to a user into a new play area based on how many points or levels have been reached by that user and/or based on what objectives that user has accomplished or helped accomplish. It can also indicate, via sending a message to the user the amount of points or specific play objectives necessary to complete a “mission” or enter the next level of play. The master control system can also send messages to the user from other users. In yet other embodiments, an interactive gaming toy may be configured to automatically download information from the master control system


The system is preferably sophisticated enough that it can allow multiple users to interact with each other, adjusting the game instantly. The master control system can also preferably interface with digital imaging and/or video capture so that the users' activities can be visually tracked. Any user can locate another user either through the video capturing system or by sending a message to another device. At the end of a visit, users are informed of their activities and the system interfaces with printout capabilities.


In another embodiment a network of transceivers may be installed at specific points throughout a facility. Players are outfitted or provided with a SRRF-compatible player identification device, sometimes referred to herein as a “token”. For example, this may be a toy, card, key chain trinket, wristband, badge, or other SRRF-compatible device having a unique token identification number (TID). In one embodiment a suitable token may comprise a standard AXCESS personnel tag clipped to a player's clothing in the upper chest area. As each player enters a specific interactive play area or “game zone” within the facility, the player's token receives a low frequency activation signal containing a zone identification number (ZID). The token then responds to this signal by transmitting both its unique TID along with the ZID, thus identifying and associating the player with a particular zone.


The token's transmitted signal is received by a transceiver attached to a data network built into the facility. Using the data network, the transceiver forwards the TID/ZID data to a host computer system. The host system uses the SRRF information to log/track the guest's progress through the facility while interfacing with other interactive systems within the venue. For example, upon receipt of a TID/ZID message received from Zone 1, the host system may trigger a digital camera focused on that area, thus capturing a digital image of the player which can now be associated with both their TID and the ZID at a specific time. In this manner the SRRF technology allows the master control system to uniquely identify and track people as they interact with various games and activities in a semi-controlled play environment. Optionally, the system may be configured for two-way messaging to enable more complex interactive gaming concepts.


In another embodiment, the SRRF technology can be used in the home. For example, a small SRRF module may be incorporated into one or more portable toys or objects that may be as small as a beeper. The SRRF module supports two-way communications with a small home transceiver, as well as with other SRRF-compatible objects. For example, a SRRF-compatible gaming toy can communicate with another SRRF-compatible gaming toy.


The toy or object may also include the ability to produce light, vibration or other sound effects based on signals received through the SRRF module to complement the operation of the toy and/or the effects achieved. In a more advanced implementation, the toy or object may be configured such that it is able to display preprogrammed messages of up to 50 characters or more on a LCD screen when triggered by user action (for example a button) or via signals received through the SRRF module. The toy or object may also be configured such that it is capable of displaying short text messages transmitted from another SRRF-compatible device.


Preferably, the SRRF transceiver is capable of supporting medium-to-long range (10-40 feet) two-way communications between SRRF-compatible toys or objects and a host system, such as a PC running SRRF-compatible software. This transceiver preferably has an integral antenna and interfaces to the host computer (and/or other consumer electronic devices) through a dedicated communication port using industry standard RS232 serial communications. If desired, each SRRF module may also incorporate a global positioning system (“GPS”) device to track the exact location of each play participant within one or more play environments.


Most desirably, a SRRF module can be provided in “chip” form to be incorporated with other electronics, or designed as a packaged module suitable for the consumer market. If desired, the antenna can be embedded in the module, or integrated into the toy and attached to the module. Different modules and antennas may be required depending on the function, intelligence and interfaces required for different devices. A consumer grade rechargeable or user replaceable battery may also be used to power both the SRRF module and associated toy electronics.


Interactive Game Play


The present invention may be carried out using a wide variety of suitable game play environments, storylines and characters, as will be readily apparent to those skilled in the art. The following specific game play examples are provided for purposes of illustration and for better understanding of the invention and should not be taken as limiting the invention in any way:


Example 1

An overall interactive gaming experience and entertainment system is provided (called the “Magic” experience), which tells a fantastic story that engages children and families in a never-ending adventure based on a mysterious treasure box filled with magical objects. Through a number of entertainment venues such as entertainment facilities, computer games, television, publications, web sites, and the like, children learn about and/or are trained to use these magical objects to become powerful “wizards” within one or more defined “Magic” play environments. The play environments may be physically represented, such as via an actual existing play structure or family entertainment center, and/or it may be visually/aurally represented via computer animation, television radio and/or other entertainment venue or source. Entertainment venues or sources may include, for example, video games, computer games, television, internet, movies and radio. These and other entertainment venues or sources can be used to provide all or part of the overall game experience in accordance with the present invention.


The magical objects use the SRRF communications system allowing for messages and information to be received and sent to and from any other SRRF-compatible object or system. Optionally, these may be programmed and linked to a SRRF-compatible master control system. Most preferably, a SRRF-compatible toy wand is provided and is configured to enable a user to interact with a master control system located within a Magic entertainment facility and/or a home-based system using common consumer electronic devices such as a personal computer or a video game system.


Example 2

A computer adventure game is provided in which one or more play participants assume the role of an imaginary character “Pajama Sam” from the popular series of computer games published by Humongous Entertainment, Inc. of Woodinville, Wash. A Pajama Sam character trading card, such as illustrated in FIGS. 13A, 13B, is provided to each play participant. The card may be packaged and sold together with the game software, and/or it may be sold separately, as convenience and market demands dictate.


A specially configured computer, video game, home game console, hand-held gaming device, game controller, or similar gaming device is provided with a reader, and more preferably a reader/writer such as described above, that is able to communicate with the card. As each play participant plays his or her favorite Pajama Sam game the Pajama Sam character represented by the card gains (or loses) certain attributes, such as speed, dexterity, and/or the possession of certain tools or objects associated with the game play. All of this information is preferably stored on the card so that the character attributes may be easily and conveniently transported to other similarly-equipped computer games, video games, home game consoles, hand-held game units, play facilities, and the like. In this manner, an imaginary role-play character is created and stored on a card that is able to seamlessly transcend from one play medium to the next.


Various other video games, home game consoles, and/or hand-held game units can also be configured to communicate with the Pajama Sam adventure card in a similar manner as described above. In this manner, a play participant can use the Pajama Sam trading card and the role play character he or she has developed with specific associated attributes in a favorite video action game, role-play computer game, internet adventure game or the like.


Example 3

Game participants are immersed in a world-wide treasure hunt adventure to locate a large, unknown amount of money stashed away in one or more Swiss bank accounts (the money and the accounts can be real or imaginary).


According to the storyline Willy Wonkers, a reclusive/eccentric billionaire, was unsure which of his many would-be heirs was worthy to receive his vast fortunes. So he provided in his will that upon his demise his entire estate was to be liquidated and all of the proceeds placed in a number of anonymous Swiss bank accounts under secret passwords known only to Willy. According to Willy's will these proceeds were to be distributed “to only such heir(s) who prove themselves worthy of inheriting my vast fortunes by successfully completing the Wonkers Worldwide Worthiness Challenge”—a series of intellectual, physical and moral challenges devised by Willy.


Game participants are invited to a reading of the will where they are identified as potential heirs to the Wonkers family fortune. Each participant is challenged to complete the Wonkers Worldwide Worthiness test and to thereby obtain the secret Swiss account number(s)/passwords and the Wonkers fortunes. Each game participant receives an RFID-enabled token having a unique identification number. The token is used to uniquely identify each player throughout the game play. Preferably, each token represents a specific character in the treasure hunt game. Thus, play participants would preferably select which character he or she would like to play. Each character would come with a unique story about who they are, how they were related to Willy and, most importantly, a touching little vignette about Willy that no one else knows. Hidden within each story is one or more unique clues that are necessary to solve the various challenges the players will soon face.


The game is preferably arranged and set up so that clues can only be successfully used by the particular characters who legitimately possess them. If any other character illegitimately obtains these secret clues and tries to use them in the game, he or she will fail the challenge. Preferably all of the clues (and possibly other, extrinsic clues) are required to complete the quest. Thus, players will preferably need to cooperate with other players in order to receive and exchange the necessary clues and/or other specified assistance required to enable each player to advance in the game. This may encourage playful interaction among the players by requiring them to work with (and possibly negotiate against) other players to see who can get the information and points they need to advance in the game.


Preferably, any sharing of information must be conducted within the rules of the game to be “legitimate” and recognized by the game. Thus, preferably, players cannot advance in the game simply by getting the relevant clue information from the internet or by asking other players. To be legitimate and, therefore, recognized by the game, cooperating players must present their tokens together to a compatible token reader and request that the information be shared between the characters. Once the information is legitimately exchanged within the context of the game, it then can be used by each player/character to solve further challenges and thereby advance in the game. However, if a player guesses the answer (even correctly) or if the clue information is obtained illegitimately, then the player preferably loses the quest and must purchase a new token.


More complex sharing scenarios could also be developed. For example, certain unique clue information could be revealed only during the course of game play and only to certain characters. Other characters would need this clue information to advance in the game and would have to figure out which other character(s) have the information they need. They would then need to find and contact another player who has the appropriate character token and who has successfully found the clue information they need. Then they would need to meet in order to make the necessary exchange transaction. Other complex sharing scenarios may require players to negotiate multi-party exchanges of information between three or more players/characters.


Preferably, the game is self-policing. That is, it “knows” when an exchange of information and/or other required assistance is legitimately given (i.e. conducted within the rules of the game) and can react accordingly. For example, the game may require players to simultaneously present their tokens to a compatible reader device. The reader would then be able to verify the identities of each character/player, extract relevant information (for example, token ID, user password, etc.), and write the relevant new information to each player's token. Once the transaction is completed, each player would then legitimately possess and be able to use the information stored on his or her token to advance further in the game using any other gaming device that can read the token.


Alternatively, the same sequence can be followed as described above, except that the token is used only to verify character and player identities (for example where the token comprises an RFID read-only tag). All other relevant information is stored in a local and/or central database. The data-base keeps track of each individual player's progress, what information/clues they have learned, who they have interacted with, points accumulated, etc. Thus, game play can proceed on any device that can communicate via the internet, such as a home computer, game console, internet appliance, etc.


Alternatively, an authenticating password may be used in conjunction with each RFID-enabled token. When two or more players present their tokens to a compatible reader device as in the examples described above, each player is given an authenticating password, which the player(s) then can enter into any other gaming platform. The password may be an alpha-numeric code that is mathematically derived from the unique ID numbers of each participating player involved in the sharing transaction. Thus, it is unique to the specific players involved in the authorized exchange transaction and cannot be used by other players (even if they copy or steal the password). When the alphanumeric number is subsequently re-entered into another device (for example, a home game console or home computer) by the authorized player, the game software can reverse the mathematical algorithm using the player's unique ID (for example, previously entered at the beginning of the game) and thereby determine and/or validate the event(s) that generated the authenticating password. Existing public-key/private-key encryption algorithms and/or the like could be used for encoding and decoding the authenticating passwords. Optionally, each authenticating password could have a “shelf life” of any desired length of time such that it must be used within an hour, a day, a week, a month, etc. This might help move the game along by keeping players on their toes. Authenticating passwords could be easily printed and dispensed on special tickets or stickers, which can be collected. Alternatively, and/or in addition, authenticating passwords can be readily printed on any ordinary cash register receipt as part of any purchase transaction (for example at a fast food or other retail establishment).


The treasure hunt game may be continual in its progression or it may be orchestrated in real time via the internet or any other mass distribution or communication medium, such as TV commercials, mini-gameboy installments, computer-animated MPEG videos. For example, each game might last several days/weeks/months, and may be launched in conjunction with a promotional/advertising campaign for a complementing movie or the like. In that event, players would preferably sign up in advance to receive their tokens to play the game or they can purchase one or more tokens at any participating gaming outlet before or during the game.


Example 4

Game participants are immersed in a “whodunit” murder mystery. For example, this interactive adventure game could be based on the popular board game “Clue™.” Players learn that a murder has been committed and they must figure out who did it, in what room, with what weapon, etc. The game is preferably live-action interactive with simulated live-news casts, letters, telephone calls, etc.


According to the storyline Major Mayonnaise is found dead in his palatial mansion of an apparent massive coronary. However, clues at the crime scene indicate that this was in fact a carefully planned murder. Based on the indisputable physical evidence, the murder could only have been committed by one of eight possible suspects. It is common knowledge that each player hated Mayonnaise and, thus, each player has been identified as a suspect in the murder. Thus, the mission is to figure out WHO DUNIT! and how.


Game play is essentially as described above in connection with Example 3. Players receive RFID-enabled tokens uniquely identifying each player. Preferably, each token represents one of the eight suspect characters in the Whodunit game. As in Example 3, above, each character would preferably have a unique story about who they are, where they were on the night of the murder, and why they dislike Mayonnaise. Hidden within the collective stories are the unique clues necessary to solve the murder mystery challenge. Players cooperate by exchanging clues and other information needed to solve the mystery. As in Example 3, the game is preferably set up and organized so that relevant clues can only be successfully used by the particular character(s) who legitimately possess them. Any player who tries to cheat will preferably be disqualified or otherwise prevented from advancing in the game.


Example 5

Game participants are immersed in a magic-themed computer adventure game. For example, this interactive adventure game could be based on the popular “Harry Potter™” series of children's books by J. K. Rowling and licensed computer games by Electronic Arts. Players learn basic magic skills as they progress through an adventure game and solve one or more challenges/puzzles.


According to the storyline players are students enrolled at the Hogwart school of witchery where they are learning witchcraft, spell casting, secret messaging and the like. But something terrible and evil has happened and it is up to each player and their fellow classmates to solve the mystery and ferret out the evil-doer and save the school.


Game play is essentially as described above in connection with Examples 3 and 4. Players preferably receive RFID-enabled tokens. Each token provides a unique identifier for the player and preferably can store his or her progress in the game. Each player begins the adventure with essentially the same magic powers, skills and abilities. Each player may also receive a toy magic wand or other similar interactive gaming device which the player must learn to use to accomplish certain goals set out in the game.


Players cooperate by exchanging clues and other information needed to solve the mystery. As in Examples 3 and 4, the game is preferably organized so that relevant clues can only be successfully used by the particular character(s) who legitimately possess them. Any player who tries to cheat will preferably be disqualified or otherwise prevented from advancing in the game.


An authenticating password system is preferably used to verify or authenticate game events and to thereby discourage cheating. These secret codes or pass words may be obtained from any participating game venue (for example, fast food venues, toy store, theme parks, etc.) or other sources that will become obvious once the game is implemented. Once a secret password is obtained, players can enter it into a specially enabled home computer game, arcade game, portable gaming device, or other device, to get secret powers and/or to find secret parts of the game otherwise unobtainable without the secret code. For example, a player may buy a meal from a fast-food vendor and as part of the meal package would receive a token and/or a secret code. The secret code preferably may be used to access a secret portion or level of a popular computer adventure game.


Most preferably (although not required) authenticating passwords are unique or semi-unique to the player(s) who possess them. For example, each password may be an alpha-numeric code that is mathematically derived from a unique ID number stored on each participating player's token or from a password the player selects. Thus, the secret code is more-or-less unique to the specific player(s) involved in an authenticated game event and preferably cannot be used by other players (even if they copy or steal the secret code). When the alpha-numeric number is subsequently re-entered into another device (for example, a home game console or home computer) by the authorized player, the game software can reverse the mathematical algorithm using the player's unique ID or user-selected password (this may or may not be previously entered at the beginning of the game) and thereby determine and/or validate the game event(s) that generated the authenticating password. Existing public-key/private-key encryption algorithms and/or the like could be used for encoding and decoding the authenticating passwords.


To make the password system more convenient, the token device may optionally include one or more entry buttons and an LCD display. When players insert the token into an enabled reader, the secret code(s) are downloaded automatically to the token device and can be displayed on the LCD screen. The token thus becomes a secret encoder/decoder device that allows players to electronically transport and send/receive secret messages and codes to each other that can only be read by players/devices that possess the correct authenticating code. An optional communication port may allow secret codes to be downloaded directly to a computer game, portable game unit or other devices using, for example, a standard USB communication port.


Example 6

A computer-animated game is provided wherein game participants learn to create various spells and/or potions by combining and mixing various ingredients (RFID-tagged gaming items) in an RFID-enabled mixing cauldron (for example, a peripheral gaming device as illustrated and described above in connection with FIG. 15C).


For example, players may be provided with multiple gaming items each comprising an RFID-tagged toy representing various potion ingredients (for example, a spider, a batwing, a potion vial, and so forth). In one embodiment, an initial quantity of such gaming items (for example, 3-6 different gaming items) may be packaged and sold together with a cauldron-themed peripheral gaming device configured to operate with a desired gaming platform (for example, a home computer, home game console, hand-held game unit, or the like). Additional gaming items may be earned by game participants as they play and progress in the game. Alternatively, gaming items may be purchased from a retail vendor and/or otherwise provided as part of one or more retail transactions.


Gameplay preferably progresses in accordance with a desired theme and/or storyline. For example, game participants may direct a virtual character (for example, a witch or warlock) in a Halloween-themed computer-adventure game. If desired, game participants may control the movements and/or activities of the virtual character using one or more input devices, such as a conventional wired or wireless game controller. At certain points in the game, players are preferably challenged to combine and mix various ingredients (RFID-tagged gaming items) in the RFID-enabled mixing cauldron to create one or more desired potions and/or spells. For example, a particular potion or spell may be required to help the virtual character progress or advance in the game.


In one embodiment, the game software may cause a potion recipe to be displayed on an associated display device. Game participants are then challenged to follow the recipe and thereby create the desired potion by dropping various ingredients (RFID-tagged gaming items) into the RFID-enabled cauldron. As each item is dropped into the cauldron, preferably the game reacts accordingly by producing one or more computer-animated visual, audible and/or tactile effects on one or more associated display devices. If desired, the cauldron may also be configured to display various light, vibration or sound effects (for example, simulating boiling, sparking, gurgling, shaking, or popping) as directed by the game software. The effects may be the same or different for each gaming item (or combination of gaming items) added to the cauldron. For example, displayed effects may be determined based on information wirelessly communicated by each gaming item as it is added to the RFID-enabled cauldron.


Recipes may be as simple or complex as desired. For example, a simple recipe may require a certain combination of gaming items (for example, three gaming items) to be placed in the cauldron (for example, one spider and two batwings). A somewhat more complex recipe may require certain gaming items to be added to the cauldron in a particular order. Yet even more complex recipes may require game participants to carefully time the addition of certain gaming items to the cauldron based on particular observed game events and/or conditions (for example, wait for the mixture to hiss and turn green, then immediately add two spiders). If desired, all or part of the potion recipe may be contained within in a riddle or a puzzle.


Those skilled in the art will appreciate that multiple thousands of possible unique recipes and ingredient combinations may be achieved using a relatively small number of gaming items. For example, providing 12 different gaming items would allow game participants to create up to 1,728 unique 3-ingredient potions, 20,736 unique 4-ingredient potions, and 248,832 unique 5-ingredient potions. Using 24 different gaming items would allow game participants to create up to 13,824 unique 3-ingredient potions, 331,776 unique 4-ingredient potions, and 7,962,624 unique 5-ingredient potions. Adding a timing element would further increase the number of possibilities because the same combination and ordering of ingredients could produce two or more different potions depending upon the timing element.


In an alternative embodiment, players are not provided with a recipe at all, but must experiment on their own (or in cooperation with other players) to discover how to use the gaming items to create various desired potions or spells. For example, players may be challenged to discover potion recipes by experimenting with various combinations of gaming items and/or the ordering and timing of adding those gaming items to the cauldron to produce various desired potions or spells. This discovery process may or may not be assisted by the game. For example, during the course of the game players may be provided with certain hints or information concerning the ingredients of a particular desired potion. As another example, players may learn that certain ingredients should never be combined with certain other ingredients. As another example, the game may react by displaying either positive or negative effects as each gaming item is added to the cauldron.


Example 7

Two or more interlinked games are provided and configured such that as a participant earns points, levels, strengths, and the like by playing one game, those earnings affect how the participant advances or progresses in a second game. For example, a player may play a first car racing game and reach “expert level” with “turbo boost” and “ten extra spare tires.” Then when the player goes to play a second car racing game the second game recognizes the player's previously earned status and upgrades. Thus, the player is able to start the second car racing game at the equivalent of expert level with turbo boost and ten extra spare tires.


In other embodiments, players may earn upgrades by purchasing certain retail items from participating retail vendors. For example, a player may be able to earn an “extreme exhaust system” by purchasing five HAPPY MEALS® at MCDONALD'S® and correctly answer twenty questions in an online quiz. In one embodiment, the player receives one or more authenticating alphanumeric codes printed on an ordinary cash register receipt. Once the player enters these codes and successfully completes the quiz, the player's status is updated to include the “extreme exhaust system.” When the player goes back to play the first car racing game and/or the second car racing game, the games will recognize that the player has earned the extreme exhaust system.


In some embodiments a purchased retail item may tie into the storyline of the game and/or correspond to a virtual item in the game. For example, a player may wish to obtain a “fire retardant driving jacket” to make the virtual game character more likely to survive a crash. The player may go to the local GYMBOREE® and purchase a particular jacket. The particular jacket comes with a special code that the player enters online to obtain the “fire retardant driving jacket.” When the player returns to play the first car racing game and/or the second car racing game, the games will recognize that that the player has earned the fire retardant driving jacket.


Although this invention has been disclosed in the context of certain preferred embodiments and examples, it will be understood by those skilled in the art that the present invention extends beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the invention and obvious modifications and equivalents thereof. Thus, it is intended that the scope of the present invention herein disclosed should not be limited by the particular disclosed embodiments and examples described above, but should be determined only by a fair reading of the claims that follow.
