     FIELD  
       [0002]     The present invention relates to portable electronic character simulations. More specifically, the present invention relates to a portable electronic character simulation module that interconnects with one or more other portable electronic character simulation modules. The image associated with a character simulation can move between any interconnected modules and can interact with the character simulations of any interconnected modules. Further, the portable electronic character simulation module can include orientation, sound, light, time and/or other sensors.  
       BACKGROUND  
       [0003]     Portable electronic units that house character simulations, for example virtual pets, gained popularity in about the last ten years, particularly with school-aged children. Typically, a virtual pet is a hand-held electronic device having a display (e.g., dot matrix LCD) and one or more buttons. An image representing a character simulation (e.g., a fanciful/alien creature, a dog, a cat, etc.) is shown on the display, and a user can interact with the character simulation via the buttons.  
         [0004]     In one virtual pet, interaction with a user influences the development and health of the character simulation. For example, a user can be able to feed the character by pressing a feed button. If the user does not feed the character for a certain length of time, the image displayed for the character can change to indicate the character is hungry or in declining health. If left unfed long enough, a simulated character can even die. Conversely, if the user feeds the character too often, the character can become fat, fail to develop to a next stage or assume a less desirable form in a next stage. Similarly, the user can be able to tend to sanitary, playtime, discipline, medical and other needs of the simulated character.  
         [0005]     While hand-held character simulations remain popular, users desire greater interactivity. In particular, there is a need for a hand-held character simulation that has greater interactivity with the user and the user&#39;s environment. Further there is a need for a hand-held character simulation that has greater interactivity with other hand-help character simulations.  
       SUMMARY  
       [0006]     In one embodiment of the present invention, a simulated character module includes a processor, a display operably coupled to the processor and a communication device operably coupled to the processor. The processor is configured to control a simulated character, and an image associated with the simulated character is displayable on the display. Further, the image is displayable on a second display of a second module to simulate movement of the simulated character to the second module. The module communicates with the second module using the communication device. Further, the image is not displayed on the display of the module if the image is displayed on the second display of the second module.  
         [0007]     In another embodiment, the image is displayable on a third display of a third module to simulate movement of the simulated character to the third module. The third module is connected to the module indirectly.

     DETAILED DESCRIPTION  
       [0025]     In one embodiment of the present invention, a character simulation module is interconnectable with one or more other character simulation modules. Preferably, the module is directly interconnectable with up to four other character modules and indirectly interconnectable with an unlimited number of other modules, but the limit for directly and indirectly interconnected modules can be any suitable number.  
         [0026]     As illustrated by  FIGS. 1A and 1B , the character simulation module  100  is preferably substantially cube-shaped; however, the module can be any suitable shape. Further, the module  100  is preferably suitably sized to be hand-held (e.g., 40 mm×40 mm×40 mm, or 47 mm×47 mm×47 mm), but can be any suitable size. At least one surface  110  (e.g., a front surface) of the module  100  includes a display  120 . The display  120  is preferably a 32×32 pixel dot matrix liquid crystal display (LCD) approximately 25 mm×25 mm in size, but the display  120  can be of any suitable type, resolution and size. Further, the module  100  has input devices  130  that enable a user to interact with the module  100 .  
         [0027]     Communication devices  140  are located on one or more surfaces  150  (e.g., a top, left, right and bottom surface) that enable the module  100  to interconnect with other modules. Preferably, the communication devices  140  and the display  120  are not on the same surface; however, communication devices  140  can be positioned on the same surface as the display  120 . When another module is interconnected with the module  100 , communication devices  140  preferably form a physical connection with the communication devices of the other module. Communication devices  140  are preferably flat metal connectors, but can be either male or female connectors which both connect two modules and help hold those modules in an interconnected position. Alternatively, communication devices  140  can communicate wirelessly (e.g., via IR, RF, other light or sonic transmissions), and can be located on the interior of the module  100  rather than at any surface.  
         [0028]     As shown in  FIG. 2 , modules  100  can be interconnected. Preferably, modules can only be connected in certain configurations. For example, a top side of one module can be connectable only to a bottom side of another module and not any other side of that module.  FIGS. 3A and 3B  show examples of correct and incorrect, respectively, module  100  interconnection when modules  100  are only connectable in certain configurations. In  FIG. 3A , each of the illustrated interconnection configurations is permitted. In contrast, in  FIG. 3B , none of the interconnections configurations illustrated are permitted.  
         [0029]     Alternatively, modules can be interconnected in any configuration, if desired. For example, any side of one module can be connected to any side of another module. Further, modules are preferably secured in place when interconnected by magnets; however modules can be secured in any other suitable manner, or modules can be unsecured and free to move relative to each other.  
         [0030]     One or more, possibly all, input devices  130  are preferably disabled or ignored when the module  100  is interconnected with another module; however, input devices  130  can remain active and continue to provide a user with the ability to provide the module  100  and/or other interconnected modules with input. The housing  160  can have any suitable color, decoration or design. Preferably, the housing  160  appearance for a particular module is created through injected plastic colors, paint or pad print; however, the appearance can be created through any other suitable manner. Further, the housing  160  is preferably substantially opaque as shown in  FIG. 1A ; however, the housing  160  can be translucent as shown in  FIG. 1B  or transparent, if desired.  
         [0031]     As illustrated in  FIG. 4 , a character simulation module (e.g., module  100 ) also includes a processor  400 , memory unit  410 , power source  420 , display  430 , one or more input devices  440  and one or more communication devices  450 . The processor  400 , memory unit  410 , display  430 , input devices  440  and communication devices are connected by a bus  450 , but these components can be connected in any suitable manner (e.g., each component being directly connected to the processor). The processor  400  and memory unit  410  are separate, but the memory unit  410  can alternatively be included as part of the processor  400 . Similarly, power source  420  supplies power directly to each component, but power can be provided from the power source  420  to the other components in any suitable manner. Further, power source  420  is preferably a battery, but can be a DC or AC connection to a standard household power line or automobile cigarette lighter slot or any other suitable source of electric power.  
         [0032]     Processor  400  and memory unit  410  control and store a simulated character. One or more images associated with the simulated character can be shown on display  430 . Preferably, display  430  is a virtual window into the simulated character&#39;s world. The behavior of the simulated character can be influenced by signals from the input devices  440  and/or the communication devices  460 .  
         [0033]     Different simulated character modules can contain simulated characters that differ in their visual representation, behavior, or other characteristics. As a result, simulated characters can be distinguished by their associated images or by their animated behavior. As illustrated by FIGS.  5 A-B, simulated characters can have genders. An image  500  resembling the general shape of a man is shown on display  510  of  FIG. 5A , and an image  520  resembling the general shape of a woman wearing a dress and having a bow in her hair is shown on display  530  of  FIG. 5B . Alternatively, simulated characters, such as the one represented by the stick figure image  540  shown on display  550  of  FIG. 5C , or the one represented by the stick figure image  560  carrying a cane, staff or stick shown on display  570  of  FIG. 5D  can be genderless. Further, as illustrated by  FIG. 5E , a simulated character can be an animal, such as the image  580  resembling a dog shown on display  590 .  
         [0034]     Two similar, or even identical, appearing simulated characters can be distinguished by animations of their behavior. For example, one character hops around and another walks on its hands. Further distinguishing characteristics include, but are not limited to, dancing a disco move, turning a cartwheel, doing a back flip, performing a somersault, flexing muscles, passing gas, belching, dancing with a cane, wearing a top hat, carrying a sword, shooting an arrow, firing a gun, using a lasso, winking, blowing a kiss, changing size, flying, swinging, having a beard, having long hair, having a Mohawk, having a moustache, wearing a skirt, being some kind of animal, being a plant and reading a book.  
         [0000]     Simulated Character Mobility Between Modules  
         [0035]     As FIGS.  6 A-I illustrate, a simulated character image  600  can leave one simulated character module and enter another. Thus, the virtual world of the character is expanded to include the interconnected modules. The image  600  associated with a character simulation can move between any interconnected modules. The identifying characteristics of the simulated character typically enable a viewer to track the image  600  as it moves from module to module. However, in some circumstances, the display of one or more modules can be cluttered, thus hampering the ability to track the image  600  for a particular simulated character.  
         [0036]     Simulated character modules  602 ,  604 ,  606 ,  608 ,  610 ,  612 ,  614 ,  616  and  618  are interconnected in a square pattern, similar to an apartment complex, but can be arranged in any suitable configuration. Initially, for the sake of example, the character simulation associated with character image  600  is maintained in simulated character module  610  and the image is displayed in  FIG. 6E  on simulated character module  610 . The image  600  can move to any of the interconnected modules. If the simulated character climbs, jumps, tunnels, teleports or otherwise goes through the ceiling of module  610 , the image  600  is displayed in module  604 , as illustrated in  FIG. 6B .  
         [0037]     Similarly, if the simulated character walks, hops, runs, jumps, tunnels, teleports or otherwise goes through the left wall of module  610 , the image  600  is displayed in module  608 , as illustrated in  FIG. 6D . If the simulated character instead goes through the right wall or the floor, the image is displayed in module  612  as in  FIG. 6F  or module  616  as in  FIG. 6H , respectively. Preferably, the image  600  can move directly between any two modules that are directly interconnected. However, some circumstance (e.g., the rules of a game or a particular module) could prevent the image  600  from moving directly between two directly interconnected modules.  
         [0038]     Preferably, the image  600  cannot move directly to a module connected only indirectly to the module currently displaying the image  600 . For example, image  600  could not move directly to module  602 . Instead, to reach module  602  as illustrated in  FIG. 6A , the image  600  must first pass through either module  604  or  608 . Likewise, the image  600  must move from either module  604  or module  612  to reach module  606 , as illustrated in  FIG. 6C . Similarly, if the image  600  is in module  616 , it could move to module  614  or module  618 , as illustrated in  FIGS. 6G and 6I , respectively.  
         [0039]     Alternatively, the image  600  is able to move directly to module  602  from module  610  even though the two modules are only connected indirectly. Image  600  could move directly between two indirectly connected modules that are even further apart (e.g., the modules do not share a side or even a corner). For example, in the alternative configuration of modules  700  illustrated in  FIG. 7 , the image  600  could move directly from module  705  to module  710 . In such an event, preferably an amount of time would pass between the image  600  leaving module  705  and appearing on module  710 . Preferably, the amount of time is approximately equal to the amount of time it would typically take the image  600  to move through the empty space  715  if it were filled by one or more modules  700 . However, the amount of time can be any length or there can be no delay at all. Further, if the image  600  teleports from module  705  to module  710 , the amount of time can be substantially the same as passes when the image  600  teleports between any other two modules.  
         [0040]     Preferably, when a character&#39;s image moves between modules, information for the character remains in the memory of the original module. Further, the character continues to be controlled by the processor of the original module. The module to which the character&#39;s image has moved transmits information about itself (e.g., other simulated objects displayed by the module, properties or rules of the module, etc.) to the module controlling the character. That module&#39;s processor determines the character&#39;s next action and transmits the information to the module displaying the character. The information can be transmitted directly to that module&#39;s display or to the displaying module&#39;s processor.  
         [0041]     Alternatively, when a character&#39;s image moves to a new module, information for the character is transmitted to the new module&#39;s memory and the new module&#39;s processor takes over control of the character&#39;s actions. Preferably, a copy of the character&#39;s information is permanently stored on the original module, and in the event that the original module is separated from the module containing the character, the character can be reinitialized in the original module. Preferably, the character will continue to exist in the non-original module until some event (e.g., a power failure) causes the character to cease to exist; however, the character can cease to exist as a direct result of its original module being separated from the module it is in.  
         [0042]     Alternatively, the original module can delete the character from memory and not retain a permanent copy. As a result, in the event that the initial module is separated from the character, the character cannot be reinitiated in the original module.  
         [0000]     Orientation Sensor  
         [0043]     As illustrated by FIGS.  8 A-D, a character simulation module  800  is preferably, but not necessarily, equipped with an orientation sensor  805 . The orientation sensor  800  includes electrical connectors  810 ,  815 ,  820 ,  825 ,  830 ,  835 ,  840  and  845 , as well as a mobile, electrically conductive member  850 . Eight is the preferred number of connectors, but any suitable number of connectors greater than or equal to two can be present. When the character simulation module  800  is resting as illustrated in  FIG. 8A , gravity causes the electrically conductive member  850  to contact electrical connectors  830  and  835 , enabling a signal to pass between the two connectors. Thus, the orientation sensor  805  detects its orientation.  
         [0044]     If the module  800  and orientation sensor  805  are rotated ninety degrees counter-clockwise, as illustrated in  FIG. 8B , gravity causes the electrically conductive member  850  to contact electrical connectors  840  and  845 , enabling a signal to pass between the two connectors. Similarly, if the module  800  and orientation sensor  805  are again rotated ninety degrees counter-clockwise, as illustrated in  FIG. 8C , the electrically conductive member  850  is again moved by gravity and now contacts electrical connectors  810  and  815 , enabling a signal to pass between the two connectors. Another ninety degree counter-clockwise rotation places the module  800  and orientation sensor  805  in the position illustrated by  FIG. 8D . The electrically conductive member  850  contacts electrical connectors  820  and  825 , enabling a signal to pass between the two connectors.  
         [0045]     The electrically conductive member  850  is preferably a metal disk or sphere, but any suitable material (e.g., a conductive liquid such as mercury) can be used. Further, the electrically conductive member  850  preferably only contacts two electrical connectors at a time at most. Alternatively, the electrically conductive member  830  can contact, and thus electrically couple, more than two electrical connectors at one time.  
         [0046]     The orientation sensor  805  enables the simulated character to react to changes, or the lack thereof, in the orientation of the module  800 . For example, if the module  800  is tilted to the left, an animation showing the simulated character falling to the left and then standing up again is displayed. Similarly, if the module  800  is tilted to the right, an animation showing the simulated character clinging to the left side of the display to prevent slipping to the right is shown. Further, sequences of changes in the module&#39;s  800  orientation can trigger different animations. For example, rotating the module three hundred sixty degrees causes an animation of the simulated character acting dizzy to be shown. It should be noted that orientation sensor  805 , having eight electrical connectors, can be capable of distinguishing different orientation categories, the four substantially similar to those illustrated and four additional orientations substantially similar to orientations reached by rotating any of the illustrated orientations forty-five degrees. Other orientation sensors can resolve orientation to different resolutions.  
         [0047]     In addition to, or instead of, triggering an animation, orientation changes or sequences of orientation changes can trigger games, change properties of the simulated world, disable one or more input devices, cause input from one or more input devices to be ignored, turn off a module display, or initiate any other suitable reaction. Further, the reaction triggered by a sequence of one or more orientation changes can vary depending on the state of the module, the simulated world, the number of interconnected modules, the configuration of the interconnected modules and/or any other suitable condition. It should be noted that different characters can react differently to identical conditions.  
         [0000]     Sound Sensor  
         [0048]     Preferably, a simulated character module has a sound sensor that provides the processor with audio input from the module&#39;s environment; however a sound sensor is not necessary to a module. The sound sensor enables a simulated character to react to noises. For example, if music is playing (e.g., from a radio, a stereo system, a computer, a musical instrument, finger tapping on a table, etc.), the character begins to dance, preferably in sync with the music; however, a character can dance without being in sync with the music.  
         [0049]     In addition to, or instead of, causing a character to dance, audio input (e.g., a spoken word, a clapping sound, a whistle, a tone, etc.) can trigger games, change properties of the simulated world, disable one or more input devices, cause input from one or more input devices to be ignored, turn off a module display, or initiate any other suitable reaction. Further, the reaction triggered by an audio input can vary depending on the state of the module, the simulated world, the number of interconnected modules, the configuration of the interconnected modules and/or any other suitable condition. It should be noted that different characters can react differently to identical conditions.  
         [0050]      FIG. 9  shows a process of operating a simulated character module that has a sound sensor. At step  900 , it is determined whether the sound sensor detects a sound. If the sound sensor does not detect a sound, the process repeats at step  900 . If the sound sensor detects a sound, at step  910 , it is determined whether the sound is associated with a simulated character module action. Simulated character module actions include, but are not limited to, causing a character to exhibit a behavior, triggering a game, changing a property of the simulated world, disabling one or more input devices, causing input from one or more input devices to be ignored, turning off a module display or any other suitable reaction. If the sound is not associated with a simulated character module action, the process repeats at step  900 . If the sound is associated with a simulated character module action, at step  920 , the action is executed and the process repeats at step  900 .  
         [0051]     Preferably, a simulated character module has a sound generating device such as a piezo buzzer or a speaker; however, a module can have any other suitable sound generating device, any suitable vibration device or no sound generation capability. Preferably, a simulated character module can detect and react to one or more sounds made by another simulated character module.  
         [0000]     Light Sensor  
         [0052]     Similarly, a simulated character module preferably has a light generating device such as an LED, a flash bulb or a laser; however, a module can have any other suitable light generating device or no light generation capability. A simulated character module can preferably detect and react to light emitted by another simulated character module.  
         [0053]     Preferably, a simulated character module has a light sensor that provides the processor with visual input from the module&#39;s environment; however a light sensor is not necessary to a module. Preferably, the light sensor detects the level of light and/or brightness in the module&#39;s environment; however, the light sensor can be more complex (e.g., a video camera) or any other suitable light detecting input device. The light sensor enables a simulated character to react to visual input from the environment. For example, if the light is bright (e.g., daytime or the room lights are on), the character becomes active and if the light is dim or off (e.g., nighttime or room lights are off), the character goes to sleep. It should be noted that the character can engage in any other suitable behavior as a result of the input provided by the light sensor. Further, different characters can react differently to identical conditions.  
         [0054]     Further, input from the light sensor can trigger games, change properties of the simulated world, disable one or more input devices, cause input from one or more input devices to be ignored, turn off a module display, or initiate any other suitable reaction. Also, the reaction triggered by input from the light sensor can vary depending on the state of the module, the simulated world, the number of interconnected modules, the configuration of the interconnected modules and/or any other suitable condition.  
         [0055]      FIG. 10  shows a process of simulating a character that reacts to light levels. At step  1000 , a light sensor detects a light level from the environment around a simulated character module. At step  1010 , it is determined whether the light level is associated with a simulated character behavior. Simulated character behaviors include, but are not limited to, sleeping, playing, praying, dancing, eating, singing, working, mating, bathing, showering, grooming, dressing, flinching, shielding the character&#39;s eyes, changing a facial expression or any other suitable reaction. If the light level is not associated with a simulated character behavior, the process repeats at step  1000 . If the light level is associated with a simulated character behavior, at step  1020 , the behavior is executed and the process repeats at step  1000 .  
         [0056]     Preferably, simulated character module can also react to the rate of change and/or frequency of change of the light level. For example, if the light level increases rapidly (e.g., a light is turned on in a dark room containing the module), the module can cause a simulated character to rub its eyes or execute any other suitable reaction. Similarly, if the light level drops rapidly, the module can cause a simulated character to stumble around blindly or execute any other suitable reaction. If the light level fluctuates erratically (e.g., the only source of light is lightning flashes in a thunderstorm), the module can cause simulated rain to occur in the simulated world or execute any other suitable reaction. Similarly, if the light level fluctuates regularly (e.g., the source of light is a strobe light), the module can cause the simulated character to dance or execute any other suitable reaction.  
         [0057]     Input from the light sensor can preferably be used together with other input sensors to produce more complex module and/or simulated character reactions; however, the light sensor can be used alone to produce any suitable module and/or simulated character reactions if desired. For example, if the light level suddenly increases when a time device of the module indicates that it is night time, the module can cause the simulated character to pull down a simulated shade or close simulated blinds on the display or execute any other suitable reaction. Similarly, other input devices can be used alone or together to produce any suitable module and/or simulated character reactions if desired.  
         [0000]     Time Device  
         [0058]     Preferably, a simulated character module has a time device or clock that provides the processor with chronological information; however a time device is not necessary to a module. Preferably, the time device is a standard clock that can be set and keeps track of the time and/or date; however, the time device can be more complex (e.g., a clock set by signals from the atomic clock) or any other suitable time device. The light sensor enables a simulated character to react to the time of day and/or time of year. For example, at night the character becomes socially active and in the day the character goes to work. Similarly, on July Fourth, the character can set off fireworks, or on New Year&#39;s Eve, the character can wear a lamp shade on its head and dance all night. It should be noted that the character can engage in any suitable behavior as a result of the time of day and/or time of year. Further, different characters can react differently to identical conditions.  
         [0059]     Further, input from the time device can trigger games, change properties of the simulated world, disable one or more input devices, cause input from one or more input devices to be ignored, turn off a module display, or initiate any other suitable reaction. Also, the reaction triggered by input from the time device can vary depending on the state of the module, the simulated world, the number of interconnected modules, the configuration of the interconnected modules and/or any other suitable condition.  
         [0060]      FIG. 11  shows a process of simulating a character that reacts has different behaviors depending upon the time or date. At step  1100 , a time device provides the processor with chronological information. At step  1110 , it is determined whether the time or date are associated with a simulated character behavior. Simulated character behaviors include, but are not limited to, sleeping, playing, praying, dancing, eating, singing, working, mating, bathing, showering, grooming, dressing, singing, drinking, setting off fireworks, waving a flag, wearing a lamp shade as a hat, wearing a costume, fasting, attending a religious service, marrying, playing an instrument and/or a song (e.g., taps), giving a gift, parading, grilling or any other suitable reaction. If neither the time nor the date is associated with a simulated character behavior, the process repeats at step  1100 . If time or date is associated with a simulated character behavior, at step  1120 , the behavior is executed and the process repeats at step  1100   
         [0000]     Simulated Character Interaction  
         [0061]     Preferably, two or more simulated characters from different interconnected modules are able to interact. For example, two characters can participate in a game, dance, fight, race, exchange information, engage in a competition, exchange virtual goods or services, become friends, date, give each other gifts, produce offspring, or engage in any other suitable interaction. The type of interaction is preferably influenced by characteristics of the simulated characters, configuration of the modules, characteristics of one or more modules, and/or environmental input; however, the type of interaction can be determined in any suitable manner.  
         [0062]     Preferably, a user can control or influence the interaction by providing input to the modules. A user can provide input by using one or more buttons, making a sound, flashing a light, changing the modules&#39; orientation, adding or removing modules, or any other suitable means of providing input to the modules. However, a user can also be unable to influence or control the interaction.  
         [0063]     Game interactions can be any suitable type of game. For example, when two or more simulated character modules are connected, the simulated characters can play against each other in a game (e.g., checkers, chess, a race, card games, fighting games, or any other suitable game). Alternatively, the characters can be pieces in a game played by one or more users.  
         [0064]     For example, users can connect, directly or indirectly, two modules, and the simulated characters of those modules can compete. Preferably, the losing character is transferred to the winning character&#39;s module, or some other module owned by the same player; however, the losing character can simply be deleted from its module and the winning player can be rewarded in another manner (e.g., by improving the competitive worth of the winning character) or any other suitable set of actions can execute. The module of the loser is preferably able to reinitiate a simulated character; however, the module can be unable to reinitiate a simulated character. Such a module would remain empty until another simulated character is transferred to it. The outcome of the competition between characters can be deterministic, but preferably there is a random or pseudorandom element to the outcome. The objective of such a game would be to amass a valuable collection of simulated characters.  
         [0065]     In another game, each player can have more than one simulated character as a piece in the game. For example, the modules can be used to play a game similar to fantasy or other theme-based card games (e.g., Magic the Gathering, Illuminati, etc.). Preferably, players take turns adding one or more modules to the interconnected group. Game play is preferably influenced by the characters in the modules added, the location to which the modules are added, a random or pseudorandom number generator, input from the players (e.g., via buttons or other sensors) and/or input from the environment (e.g., orientation, sound, light, etc.). However, game play can be conducted in any suitable manner.  
         [0066]      FIG. 12  shows a process for playing a game in which simulated characters are pieces of the game in accordance with one embodiment of the present invention. The game is preferably a two player game, as illustrated; however, the game can have more than two players, if desired. At step  1200 , a simulated character module of Player A is connected to a simulated character module of Player B. The modules are configured such that their connection initiates play of the game. Preferably, no other modules are connected to either the module of Player A or the module of Player B when they are connected; however, game play can be conducted such that one or more other modules are connected to one or both of the modules of Player A or Player B when the modules are connected.  
         [0067]     Preferably, the game includes turns during which players can take actions; however, the game can include rounds, simultaneous play and/or any other suitable system for advancing game play. At step  1205 , it is determined whether it is Player A&#39;s turn. If it is Player A&#39;s turn, at step  1210 , Player A can connect another module to the group of interconnected modules. At step  1215 , one or more of Player A&#39;s simulated characters can act. The simulated character actions can be directed by Player A (e.g., through instructions input through input devices on one or more modules; however, the simulated character actions can be determined by the configuration of the interconnected modules, by a random or pseudo-random event or in any other suitable manner. The actions can include attacking Player B&#39;s simulated characters, defenses or game points, building defenses for Player A, maneuvering, waiting, casting spells or any other suitable action. Preferably, some actions can result in the simulated character moving between modules and interacting with (e.g., fighting with or attacking) other characters.  
         [0068]     At step  1220 , it is determined whether a game ending event has occurred. If a game ending condition has occurred, at step  1225 , the game is over. If not, the process repeats at step  1205 .  
         [0069]     If, at step  1205 , it is determined that it is not Player A&#39;s turn, at step  1230 , it is determined whether it is Player B&#39;s turn. If it is not Player B&#39;s turn, the process repeats at step  1205 . If it is Player B&#39;s turn, at step  1235 , Player B can connect another module to the group of interconnected modules. At step  1240 , one or more of Player B&#39;s simulated characters can act and the process continues at step  1220 . Preferably, once a module is connected to the group of interconnected modules, the module is not removed until game play ends; however, modules can be removed at any suitable time during game play if desired.  
         [0070]     The game can also be a simulation. The user can connect two or more modules and simply observe the simulated characters actions and interactions in their simulated world, similar to watching interconnected ant farms or hamster habitats. Modules can be added to introduce new characters into the world and/or to provide new interaction options. For example, one module can enable characters in the simulated world to dance, another module can enable characters to reproduce, and other modules could give characters the ability to engage in other suitable interactions.  
         [0000]     Simulated Character Generation  
         [0071]     Preferably, a user can influence or control character attributes that are present when the character is created or generated; however, character attributes present at character generation can alternatively be uninfluenced by a user. Attributes present at character generation can include the way the character looks, communicates or acts in the simulated environment. Further, a character is preferably normally displayed in stick form, but when the character wants to communicate to the world outside of the simulated environment, it brings its head to the full screen. As a result, facial features, expressions or movements can be displayed in greater detail. Such facial features, expressions and movements can be attributes that a user can influence or control upon character generation. Further still, the simulated character can communicate with the real world (e.g., the user) via text. The text is preferably displayed in cartoon bubbles when the character brings its head to the full screen; however, the text can be presented in any suitable manner at any suitable time.  
         [0072]     Preferably, the character that is generated as a result of the user influencing one or more character attributes (e.g., appearance, temperament, language, dialect, education level, etc) can move to other users&#39; modules. The character can then cohabit in the host module and interact with the host module&#39;s characters. Preferably, the module includes a “clone” function which enables a user to keep his or her creation on one module and have one or more copies travel to other modules. Preferably, the amount of memory necessary to store a character is relatively small compared to the total available memory for a module. As a result, many simulated characters can coexist in the same module.  
         [0073]     Preferably, a simulated character attributes generator enables efficient usage of the system uC volatile memory resources with regards to character generation and storage. Attributes are preferably formed in elements and built up into a character profile, similar to police “photo fit” systems. Character profiles can be generated in accordance with random and/or user input. Alternatively a character profile can be a default profile.  
         [0074]     Preferably, one or more attributes are represented as memory addressed pixel patterns in the uC ROM; however, attributes can be represented in any suitable manner and in any suitable device. Further, characters are preferably treated as sprites, enabling simple internal code commands move them around the screen; however, characters can be displayed as any type of graphical representation and can be manipulated in any suitable manner.  
         [0075]     Preferably, firmware forms a “Virtual World” generator engine, which has a number of interaction routine libraries available; however, the generator engine can be hardware or software and need not include any libraries, if desired. Preferably, the attributes of a particular character (e.g., character personality/behavior weights or values) further modify these routines, thereby providing changing play-patterns.  
         [0076]     Generated characters can be stored in system registers/RAM, or preferably in flash memory, where they could survive a long term power-down; however, characters can be stored in any suitable storage device.  
         [0077]     Character attributes can be any suitable variable or fixed size. As an example, each attribute can be an 8-bit element (1 byte). Using such attributes, an exemplary unique character can be stored using 5 bytes, though, it should be understood that unique characters could be stored using more or fewer bytes, depending upon the size and number of attributes. Byte  1  of the exemplary character represents hair style/head gear (e.g., hat) information. Byte  2  represents facial information. Byte  3  represents body information. Byte  4  represents arm and leg type information, with the lower four bits representing the arm type and the upper four bits representing the leg type. The lower four bits of Byte  5  represent vocabulary, dialect and/or language abilities of the character. The upper four bits of Byte  5  represent Character personality/behavior information.  
         [0078]     Preferably, geographic territories can use specific parts of the bytes for their own regional attribute variations. For example, bits  00   h  to  64   h  of the facial information byte can represent facial features with American/English characteristics. Similarly, bits  65   h  to C 8   h  can represent facial features with Asian characteristics. As a result, a module distributed to an American/English user (or a user in a predominantly American/English geographic region) is preferably unable to generate oriental characters; however, modules can be configured to allow any type of character to be configured in any suitable region, if desired. Preferably, characters from other territories can still be seen, stored upon and pass through all modules, and only the character generator functionality does not give access to the library attributes specific to other territories. As a result, characters that cannot be generated in one territory may become valuable and/or sought after within that territory as rare, difficult to acquire characters.  
         [0079]     It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
A simulated character module and method of operation are presented. The simulated character module includes a processor, a display operably coupled to the processor and a communication device operably coupled to the processor. The processor is configured to control a simulated character, and an image associated with the simulated character is displayable on the display. Further, the image is displayable on a second display of a second module to simulate movement of the simulated character to the second module. The module communicates with the second module using the communication device. Further, the image is not displayed on the display of the module if the image is displayed on the second display of the second module.
