Game device, notification method, non-transitory information recording medium and program for informing displacement of game controller mat
A process control unit ( 306 ) controls a music reproduction unit ( 309 ) to output a music sound, while controlling a request content creation unit ( 305 ) to present content of a motion requested to the player. At the same time, the process control unit ( 306 ) compares content of the motion acquired from a motion content acquiring unit ( 302 ) with the presented, requested motion (and the timing) to evaluate the stepping motion of the player. Further, during the game, the process control unit ( 306 ) sequentially measures the amount of displacement of the game mat in accordance with the position, etc. of the controller, the position being detected by a controller detection unit ( 303 ). Then, when the measured amount of displacement exceeds a reference value, an alarm message is synthesized to a game screen and displayed, and the game mat displacement is informed to call attention of the player.
