Description

FIELD OF THE INVENTION

The present invention relates to computer and board games in general and in particular to such games using one or more dice.

BACKGROUND OF THE INVENTION

It is very well known to use one or more dice in games, such as backgammon and especially in board games such as ‘snakes and ladders’ and ‘monopoly’. In recent years, many of these games have been adapted for use with the computer. In the computer version of these games, the computer acts as the dice thrower and effectively takes control of that particular aspect of the game. In other words the player of the game presses a button, a key, or his mouse in order to intiate the action of the dice throwing. The player, who does not have any physical control over the action of the dice, is prevented from determining the outcome of the dice throw. Consequently, the computer versions of games are less exciting since they lack an important element of the game, the ‘feel’ and control over the dice throw.

Dice are also an integral part of certain gambling games such as craps, where the throwing of the dice and the resulting fall of the dice are the critically important constituents of the game.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

Reference is now made to FIGS. 1 and 2 . FIG. 1 is a schematic illustration of an electronic dice 10 , according to a preferred embodiment of the present invention. Electronic dice 10 is configured, in the example of FIG. 1 , to look like a standard dice having six faces, numbered form 1 to 6 . In FIG. 1 , three faces, numbered 3 , 5 and 6 , are visible and one face (opposite “3”), is lying face down on a surface 11 . Each face of the dice 10 comprises a sensor, generally designated S and individually referenced S 1 , S 2 , S 3 . S 4 , S 5 and S 6 , corresponding to each of the numbers one to six respectively. As best seen in FIG. 2 , dice 10 further comprises a wireless transmitter device such as an RFID (Radio Frequency Identification) transponder (or tag) 12 vwhich is in wireless communication with a read/write unit 14 coupled to a computer 16 .

The RFID tag 12 receives signals from each of the sensors S via a controller (not shown) which it can then transmit to read/write unit 14 . The computer 16 processes the signals received by read/write unit 14 in order to identify the face next to the surface 11 and thus, its uppermost face (“ 3 ” in the example of FIG. 1 ).

The connection between the readarite unit 14 and the electronic dice 10 is by means of a wireless communication such as, radio frequency (RF), infrared or any other suitable cordless communication.

In one preferred embodiment, electronic dice 10 comprises a plurality of sensors S which are coupled to a RFID tag 12 . It is a feature of electronic dice 10 that RFID tag 12 is capable of receiving data from each of the sensors S 1 . . . S 6 built into each face of the dice 10 and furthermore can communicate the position of the dice 10 to the computer 16 .

It will be appreciated that the present invention is not limited to a six-sided dice, but is applicable to any object having at least two faces.

The purpose of the sensors S is to determine the face upon which the dice falls. Since one face of the dice 10 is always obscured (five faces always being visible), by analyzing the signals received from each of the sensors S 1 . . . S 6 , it is possible to determine which face is face down (obscured) and thus which face is uppermost.

Any suitable type of sensor may be used, the type of sensor being selected depending upon the particular implementation. Sensors S include, but are not limited to, induction coil sensors, capacitance sensor, mechanical and optical sensors.

In a preferred embodiment of the invention a plurality of optical sensors (S 1 , S 2 , . . . S 6 ), one in each face is used. Optical sensors S include but are not limited to photodiode and photo-transistor sensors such as the model OD44L photodiode manufactured by the OKI Company of Japan. When a dice has been thrown onto a playing surface (board), for example, one of its faces will be face down and will be transmitting a “0” signal. In other words, the ‘obscured’ face will be generating a ‘dark’ current, equivalent to logic value of “0”. In contrast, all the other faces will generate a ‘light’ current, hat a logic value of “1”. The face lying closest to the board is thus known and by analysis it is possible to determine the uppermost face of the dice. The type of board (playing surface) to be used with optical sensors is one which totally seals off the light from the bottom face so as prevent the optical sensor in the bottom face from emitting a signal.

The controller may be any suitable device known in the art such as a register, processor, buffer and micro-controller.

In an alternative embodiment, a RFID transponder, preferably anti-collision to prevent interference between signals, is located in each of the faces of the dice may be used together with a metal playing surface. The face of the dice falling onto the metal surface will not able to transmit a signal. All the other five faces of the dice will be transmitting a signal and, on the basis of elimination, it will be possible to identify the uppermost face.

Any suitable type of commercially available, anti-collision, RFID transponder may be used such as the Hitag™ HT 1 transponder manufactured by Mikron Gmbh. of Gratkom, Austria.

It will be appreciated by persons skilled in the art that it is not essential that an optical sensor or, in the alternative embodiment, a RFID tag be located in each face of the dice in order to determine the value of the non-transmitting face. For a dice having n faces, a minimum of n−1 sensors need to be installed. This can be demonstrated by the example of a dice having 6 (n) faces and 5 (n−1) sensors. Should, the dice land on the face not having a sensor, five sensor will be transmtting data and by elimination, the non-transmitting face is thus next to the playing surface. Should, the dice land on one of the faces having a sensor, only four sensors will tansnit data. In this case, the non-transmitting sensor identifies the face next to the playing surface.

In the preferred embodiment of the invention, dice 10 is a ‘passive’ dice using RF transmissions to receive its energy source. In contrast to an “active” dice which contains is own source of power, such as a battery, the ‘passive’ dice receives its operating energy from a remote energy source. A description of the transmission of energy to RFID tag 12 will be described hereinbelow.

Reference is now made to FIGS. 3A and 3B which are block diagram illustrations of alternative embodiments of RFID tag 12 .

Reference is now made to FIGS. 3A and 3B which are block diagram illustration of the RFID tag 12 . RFID tag 12 comprises a read/write tag 80 comprising commerically available components including an RF transceiver 20 having memory storage means 22 , such as EEPROM connected thereto. RFID tag 12 further comprises an ID block 26 connected to a controller 27 . Controller 27 is also connected to memory means 22 and RF transceiver 20 .

RFID transponder 80 is any suitable commercially available tag, such as the TEMIC semiconductor e 5550 , manufactured by Temic Telefunken Microelectronic Gmbh of Heilbronn, Germany.

Memory storage means 22 is preferably an EEPROM (electrically erasable programmable read-only memory) chip configured to store an unique identification (ID code) for each RFID tag enabling more than one dice to be used in a system. In addition, other encrypted data can also be stored in the EEPROM 22 .

RFID tag 12 further comprises an input register 24 which is coupled to RF transceiver 20 and controlled by controller 27 .

The sensors S are coupled to input register 24 which latches the signals being transmitted by the sensors S at regular pre-detennined intervals, for example, every 0.05 msecs. Each of the sensors (S 1 . . . S 6 ), as well as the RF tag, receive their operating energy (VCC) from RF transceiver 20 .

ID block compares and checks the signal code received by the RF transceiver 20 from read/write unit 14 . The contents of the dice 10 (input register 24 and EEPROM 22 ) are only transmitted if the codes match the ID data stored in EEPROM 22 .

It is a further feature of the present invention to use an ID code which protects the electronic dice from being illegally copied. Each RFID tag within the dice is configured with its own ID code which is compared with a code transmitted by the computer. Thus, it is possible to check the legality or originality of the particular electronic dice and whether the game, or software application using the dice, is a copy or an original. In other words, the ID code acts to prevent fraudulent copying of dice 10 , and the game or application using the dice.

Since a standard transponder (tag) does not have its own energy source, in order for RFID tag 12 to transmit or receive data to read/write unit 14 , it requires energy frm an external source. In the preferred embodiment of the invention, the dice 10 receives its operating energy via electromagnetic waves transmitted by read/write unit 14 via a transceiver 32 (see FIG. 4 hereinbelow).

Thus, dice 10 does not require its own energy source. Instead, it receives its energy directly from the read/write unit 14 . Using the energy supplied by the read/write unit 14 to the sensors S, the RFID tag 12 transmits the status of the dice 10 to the computer 16 . An advantage of a passive dice is that it is not necessary to replace ten battery (or other energy source) within the dice.

In an alternative embodiment, energy may be supplied to the dice 10 by means of solar cells, drycell batteries, photo-voltaic cells or similar.

In the alternative embodiment illustrated in FIG. 3B , the transponder interface 180 (which performs functions similar to tag transponder 80 of FIG. 3A ) comprises an RF transceiver 20 having memory storage means 22 , such as EEPROM connected thereto. RFID tag 12 is similar to FIG. 3A except that the RFlD tag comprises a micro-controller 101 (instead of input register 24 controller 27 , and ID block 26 of FIG. 3A ) which is coupled to RF transceiver 20 .

The sensors S are coupled to micro-controller 101 which latches the signals being transmitted by the sensors S at regular pre-determined intervals, as described hereinabove with respect to FIG. 3 A. The functions of ID block 26 and controller 27 are carried out by micro-controller 101 . Reference is now made to FIG. 4 which is a block diagram illustation of the read/write unit 14 coupled to computer 16 .

Read/write unit 14 comprises a microcontroller 30 or control logic coupled to a base station transceiver 32 having an antenna 33 attached thereto. The station transceiver 32 is any suitable commercially available transceiver, such as model U2270B manufactured by Temic Telefunken Microelectronic Gmbh of Heilbronn, Germany.

Read/write unit 14 is preferably also coupled to the computer by any suitable means, such as serial RS232 or parallel, USB (Universal serial Bus), SCSI (small computer system interface) or keyboard interface, for example.

It will be appreciated by persons knowledgeable in the art, that the type of read/write unit 14 utilized will be deternined by the type of dice and the method of transmission. For instance, as in the preferred embodiment, the dice and the read/write unit 14 will be based on a similar RFID technology. Similarly, if the dice uses infra-red technology for transmission then the read/write unit 14 will of course be configured to receive infra-red technology.

A system utilizing the electronic dice 10 is described with reference to the flow charts of FIGS. 5A-5D , which describe the operational steps of a sample calling application 200 .

Referring to FIG. 5A , the calling application 200 sends an “ID code” and command type to the dice operating program (step 202 ). Depending on the specific command type, the computer performs the appropriate routine (stop 210 ). Two possible examples are illustrated; FIG. 5B which is a flow chart illustration for checking the authenticity of the dice and/or the software application (step 212 ) and FIGS. 5C-5D which is a flow chart illustration for checking the status of the dice (step 214 ).

It will be appreciated by persons knowledgeable in the art, that the type of read/write unit 14 utilized will be determined by the type of dice and the method of transmission. For instance, as in the preferred embodiment, the dice and the read/write unit 14 will be based on a similar RFID technology. Similarly, if the dice uses infra-red technology for transmission then the read/write unit 14 will of course be configured to receive infra-red technology.

A system utilizing the electronic dice 10 is described with reference to the flow charts of FIGS. 5A-5D , which describe the operational steps of a sample calling application 200 .

Reference is now made to FIGS. 5C-5D which is a flow chart illustration of the processing of data received from dice 10 ( 214 ). The dice 10 can exhibit one of four stages, as follows;

M1. The dice remains immobile for a predeternined time (ex. at least 1 sec);

M2. The dice is not lying on the playing surface (ex. being held by one of the players);

M3. The dice has been thrown on to the playing surface and is in motion, that is rolling on the surface for a predetermined time (t1, for example, between 0.5-1 secs); and

M4. The dice has landed on the surface at least once and is now immobile on the surface for at least t2 secs.

While the dice is in state M1 ( 300 ), that is immobile, loop 302 is performed, that is the sensors S on the dice are read by read/write unit 14 (step 304 ), and the status of the dice is checked (query box 306 ) until there is a change to state M2 ( 308 ), that is, the dice has been lifted up, for example.

If the dice has been lifted off the surface and state M2 ( 308 ) is operative, loop 310 is performed. The dice is read again (step 312 ) and the state of the dice checked (step 314 ) to ascertain whether a change to state M3 ( 316 ) has occurred.

The dice program continually reads the state of dice 10 until there is a change to state M3 ( 316 ). If state M3 has occurred ( 316 ), that is, the dice has been thrown and is rolling on the playing surface, the status of the dice is checked as to whether state M3 still applies (step 318 ).

If the dice has been rolling for more than a prodetermined time of say t1 secs (query box 320 ), state M4 applies ( 324 ). Loop 326 is performed, that is the status of the dice is read again (step 328 ) to ascertain whether the dice is stable (query box 330 ). If status of the dice has not changed, that is, it has remained stable for more than t2 secs, the result of the dice throw is transmitted to the calling application ( 332 ). Control is then returned back to the calling application ( 200 ).

If, at stage 320 , t1 secs has passed without the dice exhibiting rolling, an ‘illegal’ result is flagged and loop 322 is perfomled. That is, the application returns to state M1 ( 302 ) and steps 304 - 320 are repeated.

It will be appreciated by persons skilled in the art that the operational steps described hereinabove with respect to FIGS. 5A-5D , may be performed by the host computer 16 and/or other suitable microcontroller.

In the preferred embodiment of the invention the optical sensors place within each of the faces of the dice are coupled to the RFID tag in order to transmit the status of the dice to the reader.

It will be appreciated by persons skilled in the art that the present invention is not limited to the dice and type of sensors described in the above embodiments but may also include other types of sensors. For instance, in an altenative embodiment, an induction sensor cornprising a coil may be implanted into each face of the dice. In this case, the dice is thrown onto a metal board connected to an electric supply. The face of the dice falling onto the board induces a current thereby indicating the value of that face.

In a further alternative embodiment, a CCD (charge coupled device) camera is imbedded into the playing surface onto which the dice is thrown. A standard dice is used and the camera, which is coupled to a computer, photographs the face of the dice landing face down on the surface. The uppermost face of the dice can thus be determined. In a yet further altemative embodiment, a CCD or other digital type camera is positioned above the playing surface onto which the dice is thrown to photograph the topmost face of the dice. The camera is coupled to a computer for processing the resulting pictures.

It will be appreciated by persons skilled in the art that the operational steps described hereinabove with respect to FIGS. 5A-5D , may be performed by the host computer 16 and/or other suitable microcontroller.

Other known methods of software protection which use a hardware ‘dongle’ connected to a computer together with software to protect the application, have a disadvantage in that only a few (usually limited to two or three) “dongles” may be coupled to a computer at any one time. Thus, for a user having numerous different applications installed in his computer, each of which uses a “dongle”, it is generally not a satisfactory solution to use them.

In contrast, since the electronic dice or object uses a wireless transmission system and is not connected to the computer, there is no limit to the number of protected applications which may be run at any time.

It will be further appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described herein above. Rather the scope of the invention is defined by the claims which follow:
