Abstract

In order to cause players to feel as little communication delay as possible in a communication type match-up game, a task generating terminal records how a player dances ( 301 ) to a reproduction ( 300 ) of a music, generates a task ( 303 ) based on an input operation ( 302 ), and transmits ( 304 ) the task to a task receiving terminal. The task receiving terminal reproduces ( 306 ) a motion picture of how the opponent player dances ( 301 ) to a reproduction ( 305 ) of the music, presents ( 307 ) the task ( 303 ), and transmits a motion picture of how a player dances to the reproduction ( 301 ) of the music. The task generating terminal reproduces ( 313 ) how the opponent player dances ( 308 ) to the reproduction ( 311 ) of the music, presents ( 313 ) the task ( 303 ), and determines ( 315 ) a score based on an input operation ( 309, 314 ) for the presentation ( 307, 313 ) of the task.
