Description
FIELD OF THE INVENTION

The present invention relates to the field of board and tabletop games including miniatures. More specifically, the present invention relates to intelligent game systems for putting intelligence into board and tabletop games including miniatures.


BACKGROUND OF THE INVENTION

Miniatures games are typically played on a board or tabletop on which players control dozens to hundreds of individual miniature figures (usually ranging from ½″ to 10″+ in base diameter) in some form of tactical combat simulation. The detail of the tabletop environment, the intricacy of the miniatures and the complexity of the tactical game vary widely between the different games currently available.


All of these games have historically used dice to determine combat outcomes and pen and paper to record the progress, such as how wounded a particular figure is. The emergence of large online worlds like World of Warcraft and Everquest, with complex simulation-level physics and realism, has generated a steady pressure to make these games more sophisticated. However, this has been largely limited by players' reluctance to have to do lots of math on paper. In other words, there is no good way to reproduce the complexity of the combat of online worlds without ruining the feel of tabletop games. One manufacturer, WizKids, Inc., has developed a new type of miniature that has a “decoder-ring”-like base which is moved as the figure becomes wounded. Thus, each miniature keeps track of its own damage, movement, and other game piece information with a simple mechanical system. A window on the base shows the figure's current status and rotating the wheel changes the status as the game progresses. Although the base tracks many items of information, the information is only available as a physical state of the rotational base. Further, updating of the status of the figure is manual, as is scoring. The greater the number of players or game pieces, the more difficult it is to update player status information and scoring. But, game play, particularly for historical re-enactment games is more robust and realistic with a higher number of game pieces. Thus, the very aspect that makes miniatures games exciting to play—diverse and numerous pieces—limits the enjoyment of the game by requiring detailed updates of individual game piece information and scoring.


Enjoyment of traditional table top board games, such as Monopoly® and Sorry®, is similarly affected by extensive record keeping and scoring due to lack of computer awareness of game pieces. For example, in Monopoly®, the value of rent charged to a player who lands on a property depends upon the number of house or hotels on the property and the initial value of the property. The count of cash in the community chest similarly may need to be counted. For a player to make game play decisions, the player often must know the value of their total assets including mortgage value of their properties and available rents, and the value of their cash.


The recent decline in prices of projectors, such as digital light processors (DLP® Texas Instruments), LCD projectors, and flat panel displays, coupled with the need to simplify and facilitate the logistic portion of game play has sparked interest in increasing the interactivity of game play through computer-enhanced graphics and sound. However, the existing miniatures cannot interact with computer graphics for the same reason that a computer game cannot capture the player's information to facilitate scoring and game play. There is no computer-awareness of the miniatures.


SUMMARY OF THE INVENTION

An intelligent game system for putting intelligence into board and tabletop games including miniatures comprises one or more sensors, configured to obtain object information from an object, each sensor corresponding to a portion of an image. In some embodiments, each sensor has an address.

In an intelligent game system, the sensors further comprise a power source coupled to intelligent game piece objects are able to implement additional features in the intelligent game system and intelligent game piece objects. A controller is configured to receive the object information and to associate the object information with a sensor. A controller with a computer readable media, configured to be read by the controller and programmed with instructions for implementing a game, processes the object information along with the instructions for implementing the game and produces an updated, changing image for transmission to an image projector. The image projector then projects the updated, changing image onto the surface of the sensors.


In another aspect, the projected image is able to be a static background image of a board game such as checkers, chess, Monopoly® or Sorry®, for example. Intelligent game piece object information is able to be collected using the sensors and then transferred to the controller. The controller then updates the scoring information and game logic for display on the controller. In embodiments of the intelligent game system where the controller has no display, the image projector is able to be used to project an updated, changing image onto the surface of the sensors.


Another aspect of the intelligent game system for putting intelligence into board and tabletop games including miniatures comprises adding sound and graphics to the game.

On “wake-up” of the processor or controller 610 on the intelligent game piece object 600, or by polling by the interface electronics 115 or by the controller 110, the processor or controller 610 (FIGS. 6B and 6C) drives a message onto the communication pin 292 thereby transmitting object information to a sensor of the second type. In some embodiments, a sensor of the second type is able to be a single serial communications circuit. FIG. 2I illustrates a diagram of a powered intelligent game piece object 290 according to some embodiments. The powered object 290 is able to be used with sensors of two types as described above. One skilled in the art would recognize that a wide variety of sensors of the second type (communication) are contemplated. Further, one skilled in the art would recognize that a wide variety of sensors of the first type (presence) are also contemplated.


In the description which follows, the term “sensor” will refer to a sensor 120 or powered sensor 265 or 280, unless a distinction is noted. The term “object” will refer to an object 215 or a powered object 250 or 290 unless a distinction is noted. The term “intelligent game piece object” will refer to intelligent game piece object 235 or powered intelligent game piece object 270, unless a distinction is noted.



FIG. 3 illustrates one or more sensors according to some embodiments. The sensors are able to be encased in a flexible, portable structure enabling the sensors to be conveniently rolled up for easy transportation. In some embodiments, an AC power adapter 180 supplies low voltage power to the sensors and to the interface electronics 115. In other embodiments, a battery or power storage system is used to provide power to the sensors and to the interface electronics 115. The sensor interface cable 160 couples the interface electronics 115 to the controller 110.



FIG. 4 illustrates a method of updating a changing image and transmitting the image to a projector 130 according to some embodiments, using sensors of only one type. It will be recognized by one skilled in the art, that the method described below is able to be implemented within the controller 110, the interface electronics 115, or the combined interface electronics and controller 118. At step 410, the sensor to be read is set to the first sensor. In some embodiments, the sensor to be read is determined by a sensor address. In some embodiments, the sensor to be read is determined by other identification methods, such as a name, time slot, or mapping of the sensor to an input port of the controller. Object information is read from the sensor at step 420. The object information is then transmitted to the interface electronics or controller at step 430. At step 440, if there are more sensors to read, then the method branches to step 480 to set the sensor to be read to the next sensor, then the method continues at step 420. If there are no more sensors to read at step 440, then the application software processes the object information at step 430, and updates the image at step 460. The controller then transmits the image to the projector at step 470. The core game features of an intelligent game system are performed in the application software.

FIG. 5 illustrates a method of obtaining object information using sensors of two types according to some embodiments. At step 510, a memory to store the state of sensors of the first type is initialized to indicate that “no object” is present at each sensor. At step 520, the sensor to be read is set to the first sensor of the first type. The sensor is read at step 530. If the sensor state has changed at step 540, if an object is detected at the sensor of the first type in step 550, then the object at the sensor initiates transmission of its object information to a sensor of the second type at step 560. The receiver associates the object information with a portion of an image. If no object is at the sensor, then any object information stored for the sensor is deleted at step 570. At step 580, a check is made as to whether there are more sensors. If there are more sensors to check, the sensor to be read is set to the next sensor of the first type, and the sensor is read at step 530. If there are no more sensors to read at step 580, the method continues at step 520 where the sensor to be read is set to the first sensor of the first type.

Methods of Intelligent Game System Play


FIG. 8A illustrates a method of initializing game play for the start of a new game using an intelligent game system. At step 810, all intelligent game system components are initialized. At step 812, the user is presented with a decision whether they want to perform game piece setup manually, or automatically. If the user opts for automatic game piece setup, then at step 814 the controller sends an image to the projector to project onto the surface of the sensors, showing where the intelligent game piece objects are to be initially placed to begin game play. If the user opts for manual game piece setup, or following projection of the required game piece object locations for automatic game piece setup, then at step 816 the player(s) place intelligent game piece objects on individual sensor locations within the sensors. The placement of intelligent game piece objects onto the surface of the sensors continues until, at step 818, it is determined that no more game piece objects need to be placed. At step 820, the controller obtains intelligent game piece information from the intelligent game piece objects. At step 822, the intelligent game piece objects are associated with a player. At step 824, if another player's objects have not yet been placed, the process resumes at step 816, otherwise the process terminates.



FIG. 8B illustrates a method of initializing game play for the resumption of a game in progress using an intelligent game system. At step 830, all intelligent game system components are initialized. At step 832, the controller reads intelligent game piece object information from a computer readable media. At step 834, the controller sends an image to the projector showing required locations for intelligent game piece objects to resume a previous game in progress. At step 836, a player places intelligent game piece objects on the sensors in the locations specified by the projected image. At step 838, the controller verifies the placement of intelligent game piece object(s). If it is determined at step 840 that there are more intelligent game piece objects to place, or that one or more intelligent game piece objects are placed on incorrect sensor(s), then a prompt or error message is issued and the process continues at step 836. One skilled in the art would recognize that the prompt or error message is able to be visual, displayed on the controller on via the projector, or audio, such as a spoken message, or any other relevant signal generated with the intelligent game system or the intelligent game piece objects. For example, an intelligent game piece object comprising a sound feature is able to direct the player to correct the intelligent game piece placement by a specific sound. An intelligent game piece object comprising a light feature is able to direct the player to correct the intelligent game piece placement by a specific sequence or pattern of illumination.



FIG. 8C illustrates a method of initializing game play for resumption of a game in progress using an intelligent game system according to some embodiments. At step 850, the intelligent game system hardware is initialized. Player(s) place intelligent game piece objects on the sensors at step 852, on any available sensor. Players are able to choose to place the intelligent game piece objects at, or near, where they remember them to be from the prior session of the game in progress. But, any available sensor will do. When the placement of intelligent game piece objects is completed, at step 854 the intelligent game system reads intelligent game piece object information from the intelligent game piece objects where the information comprises the unique identifier and sensor identifier stored in the intelligent game piece object during the prior session of the game in progress. At step 856, the controller sends an image to the projector showing required locations for the intelligent game piece objects. At step 858, player(s) then relocate intelligent game piece objects to the locations shown by the projected image. The controller obtains and verifies the placement of intelligent game piece objects at step 860. When the placement of all intelligent game piece objects has been verified, the process terminates at step 862.



FIG. 8D illustrates an overview of game play of a generic game. The specific game logic, scoring, movement of players and other game specific-features is a function of the game application software, utilizing the intelligent game system and intelligent game piece object functionality. Step 899, shows the basic game engine, comprising player action, obtaining object information from intelligent game piece objects, and a game response. Starting the game at step 870, the game is initialized. Initialization of game play in an intelligent game system is able to be in accordance with FIGS. 8A through 8C, above. FIGS. 8A through 8C are illustrative of a process of game play initialization in an intelligent game system. At step 872, a player takes a player action. A player action is able to comprise the physical movement of an intelligent game piece object to another sensor in the sensors, or a player action is able to be an invocation of a game function or intelligent game piece object feature through any available input device in the intelligent game system. At step 874, the controller obtains intelligent game piece object information. At step 876, the game application software produces a response to the player action. Such a response is able to include sound and/or graphics.


At step 878, if the game is over, then the method branches to step 880, where the user is prompted whether the intelligent game system is to save game statistical information. At step 882, statistical information is saved. Such statistical information comprises information such as scoring information, location of intelligent game piece objects, and current dynamic information for intelligent game piece objects. In some embodiments, intelligent game piece object dynamic information comprises such items as weapon count, current stamina, injury statistics, accessory count and other game piece specific information. In an intelligent game piece object comprising nonvolatile memory, intelligent game piece-specific information is able to be stored within the intelligent game piece object. In some embodiments, all game play and intelligent game piece information is stored on a computer readable media. The computer readable media is able to be located within the controller, external to the controller, or is able to be a removable computer readable media. The statistical information is also able to be transmitted via network, or by email, to a remote destination for later use. If the game is not over, then a player is able to opt to pause the game in progress for later play at step 884. If the player opts to pause the game, then game state information is saved at step 886, otherwise play continues at 872. Game state information comprises any, or all, of the information described above in step 882 where statistical information is saved. In addition, if relevant, intelligent game piece object information indicating the identifier of the sensor at which each intelligent game piece object is presently positioned is stored. As with statistic information, the location of intelligent game piece objects is able to be stored in computer readable media in the controller, or a removable computer readable media, within nonvolatile storage within the intelligent game piece objects, or transferred by network to a remote server or by email.


It will be understood by those skilled in the art that the players are able to use intelligent game piece objects, or virtual game piece objects. Virtual game piece objects are projected onto the surface of the sensors. Thus, a virtual player is able to be, for example, the controller or a live game player accessing the intelligent game system via a network. Further, all players are able to be virtual players, such as for demonstrating a training mode or arcade mode where the game plays against itself, using virtual game piece objects to demonstrate game play or to attract players to the game by demonstrating its features and game play. Since the virtual players are mere images whose location is determined by the controller, intelligent game piece objects and virtual game piece objects are able to occupy the same sensor location.


In operation, a system for putting intelligence into board and tabletop games including miniatures comprises a game play surface including sensors capable of identifying the location and unique identity of game pieces on the game play surface. Each sensor in the game play surface corresponds to a portion of an image to be displayed by an overhead projector onto the game play surface. Interface electronics coupled to the game play surface read the sensors comprising the game play surface. Each sensor reading comprises an identifier of the sensor and at least an identifier of a game piece on the sensor, if a game piece is present on the sensor. For each sensor in the game play surface, the interface electronics pass the sensor identifier and the identifier of any game piece on the sensor, to the controller. The controller comprises a computer readable media programmed with a game application software. The game application software receives the sensor identifier and game piece identifier for each sensor and utilizes the information to maintain scoring of the game and provide enhanced game play features.


The controller further comprises an interface for transmitting the game play image to an overhead projector such as a DLP® or LCD projector. The controller further comprises an interface for transmitting sound to a sound system or speakers connected to the controller. Enhanced game play features include graphics projected onto the game play surface and sounds transmitted to the sound system or speakers to enhance the game playing experience. Game logic includes scoring, enabled by the controller's awareness of the location and identification of game pieces on the game play surface. Information gathered from the sensors comprising game state information, game play statistics, and game piece information are able to be stored to a computer readable media within the controller, or a removable computer readable media, to enable users to resume a game in progress at a later time or on a different system and to maintain statistics of game play and statistics for individual game pieces.
