DETAILED DESCRIPTION

FIGS. 1A and 1Billustrate an example of a video game system in accordance with aspects of the invention. The video game system provides video-game play, and is able during video game play to dynamically change the number of players playing the video game. The video game system is illustrated inFIG. 1Abeing played by one player, a first player105. The video game system is illustrated inFIG. 1Bbeing played by two players, the first player105and a second player106.

Embodiments of the present invention provide for in-game transition between the case illustrated inFIG. 1A, in which one player plays the game, and the case illustrated inFIG. 1B, in which two (or more) players play the game. As illustrated, the video game is a music video game, in which each player is provided instructive cues and is provided a score based on extent of compliance with the instructive cues, with in some embodiments a group score also being provided. In other embodiments the video game may be other types of games. In most embodiments video game play follows a linear progression, with for example a timed sequence of events for players to react to.

Each player controls actions in the game using controllers. A first controller101is used by the first player and a second controller102is used by the second player. As illustrated inFIGS. 1A and 1B, the game controllers are in the form of musical instruments. In other embodiments the game controllers may be in other forms, including game controllers commonly used in video game play, or even “virtual” game controllers in which a camera, for example, tracks player movements. The controllers include one or more input devices for the game players to signal game actions. Example input devices include buttons, switches, accelerometers, position sensors, and microphones. In some embodiments, as shown inFIG. 1A, the controller has a guitar shape and may include, for example, a strum bar and fret buttons as game player input devices.

A processing system111, generally including a processor configured by game program instructions, determines game states and commands presentation of game video on a display123and game audio on associated speakers121. The processing system, for example, may be a personal computer or game console with a processor, or multiple processors or processing cores, for executing program instructions providing for game play. The instructions providing for game play and associated data are generally stored on removable media, for example, an optical disk. Accordingly, the processing system may include an optical drive, for example, a CD-ROM drive, a DVD drive, or Blu-ray drive, for reading the instructions and associated data. The program instructions include, variously in different embodiments, program instructions for processing inputs from the controllers, determining game states, and selection or generation of audio and video data for presentation. The processor generally changes game play sounds in response to inputs from the controllers.

The processing system includes circuitry for supplying audio and video signals to the display device123. The display device is generally coupled to the processing system by an audio-video cable113. The display device may also be coupled to the processing system wirelessly. Wireless coupling may use a wireless adapter at the display device, the processing system, or both. In some embodiments, the processing system is integrated with a device having a built-in display and built-in speakers.

The processing system includes circuitry for receiving the game players' inputs from the controllers. The processing system is coupled to the controllers by data links. The first controller is coupled to the processing system by a first data link145; the second adapter is coupled to the processing system by a second data link146. In some embodiments, the data links are universal serial bus (USB) cables, and the controllers and the processing system include USB interface circuitry. In some embodiments, the data links are wireless links, and the controllers and the processing system include wireless receivers, transmitters, or transceivers as appropriate.

In many embodiments, as illustrated inFIGS. 1A and 1B, the display device is a television that provides both visual and sound reproduction. In other embodiments, the audio and video signals are reproduced by separate devices. The display device123displays video images of game play, generally as commanded by the processor or other circuitry of the processing system. In the embodiment ofFIG. 1A, the display device shows a screen shot of video game play with combined display of a music video125overlaid by a first instructive cue track127with portions highlighted according to actions by the first game player.

In the embodiment ofFIG. 1B, the display device shows a screen shot of video game play with combined display of a music video125overlaid by a first instructive cue track127and a second instructive cue track128. The first instructive cue track is associated with the first player; the second instructive cue track is associated with the second player. Other embodiments may have a greater number of players, for example, four players, and matching number of instructive cue tracks. Each instructive cue track includes instructive cues and, in some embodiments, status indicators for the associated player. When a player joins other players playing that were already playing the video game, an instructive cue track for the player is added while the other players continues their game play without disruption. Similarly, when a player leaves other players that continue playing the video game, the instructive cue track for the player is removed while the other players continue their game play without disruption. Embodiments of processes of players beginning or ending playing the video game are more specifically described below.

FIG. 2is a block diagram of a processing system, for example, a personal computer or game console, useful in accordance with aspects of the invention. As shown inFIG. 2, a processor211is connected to other components via a bus213. Other components include a main memory215and a removable memory interface217generally coupled to a removable memory device, for example, a DVD-ROM drive. The processor may execute instructions from the removable memory device to control game play and store game state information in the main memory. For example, the instructions may include video game instructions to facilitate video game play of, for example, the music based video game described with reference toFIGS. 1A-B.

The processor is coupled to an audio driver221and a video driver223. The audio driver produces sound signals and the video driver produces image signals. The sound signals and image signals are transmitted from the processing system via a display I/O device225. The display I/O device generally supplies the sound and image signals to a reproduction device or reproduction devices external to the processing system.

The processor may also be coupled to a user I/O device231, a wireless transceiver233, an Internet I/O device235, and other circuitry239. The user I/O device may receive signals from game controllers, with the controllers generally being used by game players and providing game player inputs, for example, during game play. Alternatively or additionally, the processing system may receive player inputs via the wireless transceiver. The Internet I/O device provides a communication channel that may be used, for example, for game updates.

FIG. 3is a flowchart of a process for a video game in accordance with aspects of the invention. In some embodiments, the process is performed by a processing system executing program instructions, for example, the system ofFIG. 2. In some embodiments program instructions for performing the process, for example by the system ofFIG. 2, are stored on a computer readable medium, for example in non-transitory media such as, in various embodiments, computer memory, CD-ROM, DVD, or flash drives. In some embodiments the video game is a music-based video game, for example one in which instructive cues are presented to a game player and a player is evaluated based on extent of compliance with the instruction cues, generally with musical accompaniment to the instructive cues or compliance with the instructive cues. The process may begin, for example, when a game player inserts a removable memory device into a game system, when a game system is turned on, or when a selection is made from a menu of the video game.

In block304, the process provides game play. In most embodiments provision of game play is provided throughout the process ofFIG. 3. The game play may command presentation of audio and video. The video may be images, which may be rendered by the processor or associated circuitry. The audio and/or video provides a sequence of events, which may repeat in some embodiments, for a game player or game players to respond to, and in many embodiments the sequence of events are a timed sequence of events. In some embodiments the sequence of events is a course of a racetrack or racecourse. In some embodiments the sequence of events is for a music-based game, and the sequence of events may be progression of play of a piece or song. For a music-based game the video may be of a band performing, a concert venue, or a dance floor. The band may include musicians whose roles the game players will perform. The audio includes multiple tracks, with the tracks associated with the various musicians or musical instruments in various embodiments. For example, if a game player is playing as a bass guitarist, one music track includes sounds of the bass guitar, and the other sounds of the song are included in one or more other music tracks. The game includes display of an instructive cue track for each game player. The instructive cue tracks may be displayed as overlays on portions of the video or rendered images. Each instructive cue track includes instructive cues, which may be termed gems, to provide the associated player with instructions of actions to perform on a controller, and a time to perform the actions. The process may use colors and positions of the gems to signal expected player actions. Likewise the process may alter the display of the gems to signal how well the player has performed, and determine a score for any active player. In one embodiment, the gems initially appear in an upper portion of a display screen and move generally toward a lower portion of the display screen. A horizontal NOW bar may be displayed in the lower portion of each instructive cue track with many player actions instructed to be performed when gems reach the NOW bar. The instructive cue track, or other portions of the display, may include a score indicator, a power meter, and other indications of game status.

In block306, the process checks if a player has joined the video game. The process may determine that a player has joined the video game based on receiving a specific signal or sequence of signals from a controller or, in some embodiments, any signal from a controller not already associated with a game player currently playing the game. In some embodiments, the process determines that a player has joined the game based on receiving any signal from a controller not previous included in the video game. If a player has joined the video game, the process continues to block308; otherwise, the process continues to block310.

In block308, the process adds audio and/or video information for the player joining the game. The video may be for example a lane for a vehicle to be driven, or in some embodiments a representation of a vehicle on a track or course. In a music-based game the video may be an instructive cue track for the player joining the game. Adding the video information may include repositioning video information for the other player(s). For example, in a music-based video game adding an instructive cue track may include repositioning instructive cue tracks associated with players who joined the video game previously. The process may also determine game options, such as a skill level, for the added player.

In block310, the process checks if a player has selected to quit the video game. The process may determine that a player has selected to quit the video game based on receiving a specific signal on the controller used by the player. In some embodiments, the process determines that a player has selected to quit the game based on not receiving any signals over a predefined period of time from the controller used by the player. If a player has selected to quit the video game, the process continues to block312; otherwise, the process continues to block314.

In block312, the process removes video associated with the quitting player from the video game. In addition, in many embodiments the process, as part of providing game play, ceases to evaluate player compliance with instructive cues, or determining changes to the quitting players score or changes to a group score based on the quitting player's lack of compliance with the instructive cues. For example, in a music-based video game the process may remove an instructive cue track for the quitting player from the video game. Removing the instructive cue track may include repositioning the instructive cue tracks associated with other players of the video game.

In block314, the process checks if play of the video game should exit. The process may determine that it should exit based completion of a game sequence, for example, reaching the end of the song begun in block302. The process may also determine that it should exit based on receiving an exit signal on a controller used by a sole active player. If the video game should exit, the process returns; otherwise, the process returns to block304.

FIG. 4is a flowchart of a further process for video game play in accordance with aspects of the invention. In some embodiments, the process is performed by a processing system executing program instructions, for example, the system ofFIG. 2. In some embodiments program instructions for performing the process, for example by the system ofFIG. 2, are stored on a computer readable medium, for example in non-transitory media such as, in various embodiments, computer memory, CD-ROM, DVD, or flash drives. The process may provide game play for another video game process, for example, the video game process illustrated inFIG. 3. In some embodiments, multiple video game play processes perform concurrently for each of multiple game players.

The process may be used, in some embodiments, for a music-based video game that includes presentation of audio, such as a piece or a song, and associated video, such as actual or rendered images of a band performing or a concert venue. The band may include a musician whose role the game player will perform. In some embodiments the audio includes multiple tracks with one of the tracks being associated with the game player. For example, if the game player is playing the game as a bass guitarist, one music track includes sounds of the bass guitar and the other sounds of the song are included in one or more other music tracks. The game includes display of an instructive cue track for each game player. The instructive cue tracks are displayed, for example, as overlays on portions of the video. The instructive cue track includes instructive cues, or gems, to provide the player with instructions of actions to perform on a controller, for example, a guitar controller. Expected player actions may be based on colors and positions of the instructive cues. In one embodiment, the instructive cues initially appear in an upper portion of the instructive cue track and move generally toward a lower portion. A horizontal NOW bar may be displayed in the lower portion of the instructive cue track with many player actions instructed to be performed when instructive cues reach the NOW bar. The instructive cue track may include a score indicator, a power meter, and other indications of game player status. In some embodiments, multiple players may play the same role in the game. Accordingly, the players may share instructive cues.

In block402, the process checks if a player is active. For example, the game may allow for M players, and the process may check if a player N is active, N ranging from 1 to M. The process may determine that the player is active based on receiving signals from a controller associated with player N, or receiving signals indicating a change in state of an input device of the controller. In some embodiments the process may determine that the player is active based on having received signals from the controller indicating a change in state of an input device of the controller within a predetermined period of time, for example in the immediately preceding five seconds. In some embodiments, whether a player is active is based on a status variable associated with the player. The status variable may have values indicating, for example, player joining, player active, player paused, player exiting, or player absent. If player N is active, the process continues to block404; otherwise, the process continues to block420.

In block404, the process determines the player's compliance with expected or instructed performance. Compliance is generally determined using inputs from the player received from a game controller associated with the player. The inputs received are compared to actions corresponding to the instructive cues contained in the instructive cue track. For example, in an embodiment with instructive cues moving toward a NOW bar, when certain instructive cues or combinations of instructive cues reach the NOW bar, a corresponding player manipulation of the controller is considered correct. In a racing game embodiment, a player's compliance may be based on steering actions of a controller. Often, player compliance is based on the specific player manipulation of the controller and the timing of the player's actions.

In block406, the process updates graphics associated with the player, for example the instructive cue track associated with instructive cue track N. The update may be based on the player's determined compliance from block404and progression of the game. The updated instructive cue track may indicate the player's compliance, for example, by changing a hue, an intensity, or a size of an instructive cue. Additionally or alternatively, the process may use sounds to signal the degree of compliance, for example playing a note or portion of a song or piece at a normal volume if there is compliance with an instructive cue, and muting or partially muting the note or portion of the song or piece if there is a failure to comply. The updated instructive cue track may also include added instructive cues instructing the player on future actions to perform on the controller. The new instructive cues may correspond to upcoming notes in the music. In some embodiments, any player action may be considered correct. In these “free play” embodiments, the instructive cue track is updated to indicate the player's actions, for example, by showing musical notes corresponding to the player's manipulation of the controller.

In block408, which is optional in some embodiments, the process adjusts volume or otherwise changes audio associated with the player. For example, the process may adjust volume of a music track based on the compliance determined in block404. Generally, the music track associated with player N is played with a higher volume when the player exhibits a relatively high level of compliance and at a lower volume when the player exhibits a relatively low level of compliance. When multiple players are playing the game as the same character, the process may pan the sound associated with the character toward the player with a higher compliance. Panning the sound may include changing an audio balance.

In block410, the process adjusts the score for player N based on the compliance determined in block404. In some embodiments the process may also update a group score based on the extent of compliance, with the group score reflecting the extent of compliance of all players for example. In some embodiments, the score is a team, or band, score for multiple game players. The band score may include nominal contributions for players who are not active. For example, when two game players are playing as a band in a game for three band members, the score may include a nominal contribution for the missing band member. In most embodiments the process also adjusts or commands adjustment to a displayed or presented score indicator(s).

In block420, the process checks if the process should exit. Exiting may be based, for example, on whether the players are active in the game, on the elapsed time since the process started, on the player's completion or failure to complete a sequence tasks, or, in a music-based game, completion of a song in the presented audio. If the process should exit, the process returns; otherwise, the process returns to block402. The process may save information about the player, for example, the player's score and performance level, before returning.

FIG. 5is flowchart of an embodiment of a process for adding a player to a video game in accordance with aspects of the invention. In some embodiments, the process is performed by a processing system executing program instructions, for example, the system ofFIG. 2. In some embodiments program instructions for performing the process, for example by the system ofFIG. 2, are stored on a computer readable medium, for example in non-transitory media such as, in various embodiments, computer memory, CD-ROM, DVD, or flash drives. The process may provide players for an associated video game process, for example, the video game process illustrated inFIG. 3. The process may be used with a video game that includes display of an instructive cue track for each game player. Each instructive cue track includes indicators instructing actions for the associated player to perform and indications of how well the player has complied with the instructions. The instructive cue track may include a score indicator, a power meter, and other indications of player status.

In block502, the process checks if a player is being added to the video game. The process may determine that a player is being added to the video game based on receiving a specific signal or sequence of signals from a controller or, in some embodiments, any signal from a controller not already associated with a game player currently playing the game. If a player is being added to the video game, the process continues to block510; otherwise, the process returns.

In block510, the process adds an instructive cue track associated with the added player. The instructive cue track includes information associated with the player. The instructive cue track is generally dynamic and is frequently updated during game play. In addition to adding the instructive cue track, the process may create an initial player state or add player information to a game state of an associated video game process. In some embodiments, the initial instructive cue track includes prompts for the player to select options for her game play. In addition to adding the instructive cue track for the added player, the process may reposition instructive cue tracks associated with other players.

In block512, the process determines the type of character being player by the player being added. The type of character may be determined by reading identification or configuration information from the controller or by selection from a menu presented to the player. The type of character, in a music-based game, may include what type of instrument the character performs with.

In block514, the process determines player options. The process may determine the options by presenting choice to the player within the instructive cue track for the player. The player may enter selection of choices by way of the controller. The options include choice such as difficulty level. In some embodiments, the options may include scoring methods, for example, whether the player is scored individually or as a member of a band.

In block520, the process activates the added player in the game. In some embodiments, the process activates the player by setting a status variable in an associated video-game process. The process may provide a countdown to signal the player to begin active game play. When the player is activated in a game with other players, in some embodiments the activated player's score is initialized based on scores of the other players. For example, the score of the activated player may be set equal to highest score of the other players, the lowest score of the other players, or an average of the scores of the other players. Thereafter the process returns.

FIG. 6is flowchart of a process for removing or suspending a player to a video game in accordance with aspects of the invention. In some embodiments, the process is performed by a processing system executing program instructions, for example, the system ofFIG. 2. In some embodiments program instructions for performing the process, for example by the system ofFIG. 2, are stored on a computer readable medium, for example in non-transitory media such as, in various embodiments, computer memory, CD-ROM, DVD, or flash drives. The process may remove players for an associated video-game process, for example, the video-game process illustrated inFIG. 3. The process may be used, in some embodiments, with a music-based video game that includes display of an instructive cue track for each game player. Each instructive cue track provides display for the associated player. The process may be performed repeated for each player playing the video game.

In block602, the process checks if the player should be suspended from game play. Whether the player should be suspended may be determined based on inputs the player provides using a game controller. If the player should be suspended, the process continues to block604; otherwise, the process continues to block606.

In block604, the process suspends the player from the game. In some embodiments, the process suspends the player by setting a status variable in an associated video-game process. The process may, in some embodiments, change game play options for the player while the player is suspended. For example, the player may change game characters or a difficulty level. Thereafter the process continues to block610.

In block606, the process activates the added player in the game. In some embodiments, the process activates the player by setting a status variable in an associated video-game process. In some instances, the player may already be active when the process performs block606.

In block610, the process checks if the player is to be removed from game. Whether the player is to be removed may be determined based on inputs the player provides using a game controller. The inputs may be selections from a menu of choices the process provides the player. If the player is exiting the game, the process continues to block612; otherwise, the process returns.

In block612, the process removes the instructive cue track associated with the exiting player from the video-game display. In some embodiments, the process removes the instructive cue track by setting game state information in an associated video-game process.

In block614, the process sets the volume of the music track associated with the exiting player to full level. For example, if the player was playing as a drummer, the volume of the drum track is returned to a full or nominal level, whereas while the player was actively playing the video game, the volume of the drum track may have increased or decreased in response to compliance of the player with instructive cues. In some embodiments, the process sets the volume of the music track by setting game state information in an associated video-game process.

In block620, the process checks if the player exiting the video game is the last player. The process may determine whether the player is the last player using information from the video game state indicating the number of players. If the player exiting the video game is the last player, the process returns; otherwise, the process continues to622.

In block622, the process repositions the instructive cue tracks for remaining players. In one embodiment, the process shifts the remaining instructive cue tracks so that they are spaced approximately evenly across the display screen. The process may additionally resize the remaining instructive cue tracks. For example, the process may make the instructive cue tracks wider. Thereafter the process returns.

Although the invention has been described with respect to certain specific embodiments, it should be recognized that the invention comprises the novel and unobvious claims supported by this disclosure, along with their insubstantial variations.
