Patent ID: 7850525

Claim:
A data processing method performed in a video game device for providing a video game in which an action and a position of a player character in a virtual space is determined based on an event signal from an input device, such that a game is generated and displayed on a display, the game image including a radar image which indicates a positional relationship between the player character and an object positioned within a predetermined distance from the player character, the method comprising: detecting, by the video game device, the event signal from the input device, and determining sound characteristic information and an effect sound based on the event signal; identifying, by the video game device, a first sound source position in the virtual space based on a current action and a position of the player character based on the event signal; determining, by the video game device, a propagation mode based on the sound characteristics information and the first sound source position, the propagation mode including at least one of a reachable range of the effect sound, an intensity of the effect sound depending on a distance from the sound source position, and a propagation speed of the effect sound; determining, by the video game device, a second sound source position on the radar image based on the first sound source position; and generating, by the video game device, a wave pattern image on the radar image based on the propagation mode and the second sound source position, the wave pattern image indicating a wave pattern of the effect sound spreading out from the first sound source position in the virtual space, and performing control of displaying the wave pattern image on the radar image on the display.
