Patent 6,786,821 abstract:
To increase a feeling of competitiveness between players of a music-oriented game. Based on evaluation of performance of the first and second players on their steps, the number of times step guidance is presented is varied. Specifically, while reference arrows 46, 48 are displayed, a plurality of timing guidance arrows 50, 62 approaching the reference arrows 46, 48 are also displayed on a game screen image 40, whereby a state of step timing gradually arriving is shown to the player. In addition, the number of timing guidance arrows 50 62, namely the number of times step guidance is presented to each player, is changed based on the result of evaluation on steps by each player.
Patent 6,695,694 abstract:
To evaluate a game playing performance from a new point of view, a control method for controlling a game machine allowing a player to enjoy stepping while listening to game music, comprises the steps of detecting whether or not the player puts their foot or feet on each of a plurality of step positions; judging, based on a detection result on the step position, according to which, of a plurality of pattern changes, a state of the player's feet relative to the plurality of step positions has changed to; calculating, based on the determined pattern change, an energy consumption amount due to a change of the state of the player's feet; calculating an accumulative energy consumption amount by accumulating an energy consumption amount calculated after a predetermined timing; and reporting the accumulative energy consumption amount calculated to the player.
Patent 6,758,756 abstract:
The present invention relates to a method for controlling a novel video game in which dancing is used as a factor in the behavior of a character, a machine for the video game, and a medium in which a program for the video game is recorded, and makes it possible to dance characters 611 and 612 displayed using 3-D polygons in time with music, to evaluate their dance skills based mainly on whether dance actions are in time with the music, and to proceed with a story by winning matches with a computer or to match with other players.
Patent 6,320,110 abstract:
A music game device is provided in which a player manipulates a manipulation unit in conformity with music. The device includes an input unit for setting play information including a plurality of tunes to be successively played and a play order of the plurality of tunes, a storage unit for collectively storing the play information, an automatic setting changing unit for automatically changing a part of the play information set by the player to a preset standard play information if the play information set by the player includes a setting which cannot be executed by the music game device, and a reproduction unit for successively reproducing the plurality of tunes in the play order based on the play information stored in the storage unit.
Patent 6,227,968 abstract:
Rhythm sensations can be represented in time to music by using the entire body and to create powerfulness and rhythm sensations. Stepping position indication data which is set by a rhythm setting section is read from a stepping position indication data memory, and the stepping position instruction contents are scrolled and displayed on a monitor by a scroll display control section, thereby performing instructions of the stepping position and the stepping operation timing. When the fact that a player steps on a step-on base section in accordance with the display contents of the monitor is detected by a cable switch and this is input from a stepping operation monitor section, a score proportional to the timing deviation is calculated by an amount-of-deviation detection/totaling section, and next, an evaluation is performed by the rhythm setting section. Then, the next stepping position indication data is set according to the evaluation result.
Patent 6,450,888 abstract:
Disclosed is a game system which matches a player's tastes. In a game system operating in time with music, it is possible to select an edit mode for editing timing data which define timings of operations. In the edit mode, an edit window having a predetermined display range is displayed on a screen of a display device in correspondence with information representing a position in a tune. Images in the edit window are scrolled so that the position of a target to be edited set inside the edit window moves forward and backward through the tune. When an operation is performed to provide marks, timing data for showing an operation timing of a control member provided in correspondence with the operation is provided at the position of the edit object in the edit window, and in addition, the timing data during editing is updated so that the position in the tune corresponding to the position of the edit object is defined as a operation timing.
Patent 6,582,309 abstract:
A game system has a display monitor for displaying a game image, a plurality of control buttons manually operable by a game player, and a memory for storing data representing timings to operate the control buttons, respectively. The game system has a control operation indicating function for displaying in the game image an image for indicating the timings to operate the control buttons based on the data stored in the memory, and an obstructing function for generating an obstructive effect in the image for indicating the timings to operate the control buttons, to obstruct an attempt of the game player to grasp the timings to operate the control buttons.
Patent 6,607,446 abstract:
Disclosed is a music game system in which the attraction of a game is increased by effectively using limited music data. The music game system comprises an input device 4 for outputting signals in correspondence with the operation states of push-switches 5; a ROM 30a in which are stored music data for reproducing multiple tunes, and timing data of each tune defining a procedure for operating the push-switches 5 in correspondence with the tune reproduced based on music data; display devices 24,3 for displaying game screens; music reproduction devices for 26, 32 reproducing the music data; and a CPU for reproducing a predetermined tune by the music reproduction devices and for guiding the player in operation procedures of the input device 4 in correspondence with the reproduced tune, a medley tune comprising parts of the multiple tunes linked together being reproduced, and the operation procedure of the input device being guided in correspondence with the medley tune.
Patent 6,659,873 abstract:
Data link-up between multiple game devices can be more flexibly achieved. A game system (1) comprises a game device for business (2) and a game device for use at home (3), which execute games in accordance with predetermined programs, it being possible to exchange information between these games devices, and the game device for business (2) comprises an information output device for outputting judgement information for judging whether predetermined conditions have been satisfied in the game device for business (2). The contents of the game executed on the game device for use at home (3) are changed based on the judgement information output from the game device for business (2). For example, when a predetermined game result has been achieved in the game device for business, the content of the judgement information is updated, and a hidden element appears in the game device for use at home (3) in correspondence therewith.
