Patent ID: 8167692

Claim:
A video game device, comprising: a display unit for displaying a game image; a position inputting unit for inputting a position on a screen of the display unit; a memory for temporarily storing data; display control programmed logic circuitry for generating a game image showing an appearance of a game space in which a moving character can move within, and displaying the game image on the display unit; storage control programmed logic circuitry for successively storing position data representing the position inputted through the position inputting unit as valid position data in the memory during a period from a start of a position inputting operation through the position inputting unit until an end thereof; invalidation programmed logic circuitry for successively invalidating position data among a group of valid position data stored in the memory for which a predetermined amount of time has elapsed since the position data is stored in the memory, in order from old positioned data; trace display control programmed logic circuitry for overlaying and displaying a trace image on the game image showing an appearance of the game space, based on the group of valid position data stored in the memory; and game process programmed logic circuitry for controlling a movement of the moving character within the game space using the group of valid position data stored in the memory.
