Image display device, computer readable storage medium, and game control method

A game control method for a game device that controls progress of a game in which a player performs an operation on an object as a stereoscopic image virtually recognized by the player, the method comprising:

• an image display step for displaying a parallax image on a display screen;
• a first coordinate calculating step for calculating virtual spatial coordinates of a stereoscopic image to be recognized by the player viewing the parallax image;
• a second coordinate calculating step for calculating spatial coordinates of an operating body to be operated by the player;
• and
• an event generating step for generating a certain event accompanying a change of at least one of the parallax image and an image on the display screen other than the parallax image when a distance between the spatial coordinates of at least one point of the stereoscopic image calculated in the first coordinate calculating step and the spatial coordinates of at least one point of the operating body calculated in the second coordinate calculating step is equal to or less than a certain threshold.

A computer readable storage medium having computer executable instructions stored thereon that, when executed by a computer, cause the computer to:

• display a parallax image on a display screen;
• calculate virtual spatial coordinates of a stereoscopic image recognized by the player viewing the parallax image;
• calculate spatial coordinates of an operating body to be operated by the player;
• and
• generate a certain event accompanying a change of at least one of the parallax image and an image on the display screen other than the parallax image when a distance between the calculated spatial coordinates of at least one point of the stereoscopic image and the calculated spatial coordinates of at least one point of the operating body is equal to or less than a certain threshold.
