<p><P>PROBLEM TO BE SOLVED: To advance a game process without trouble by using the direction of motion of a pointing device even if the position pointed by the pointing device can not be easily specified. <P>SOLUTION: The game system 10 comprises the pointing device 26 for pointing an optional point in a game screen displayed in a display device 34 and an acceleration sensor mounted in the pointing device. A processor of the game system 10 repeatedly specifies positions pointed by the pointing device and detects the change of the specified positions, and determines the direction of motion of the pointing device based on the acceleration detected by the acceleration sensor. If the positional change is detected, the game process is executed based on the positional change. If the positional change is not detected, the game process is executed based on the determined direction of motion. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
