Abstract:
1. A video game device in which a real interface device that a player within a real space manipulates is represented by a virtual interface device within a virtual space, the video game device comprising: position detecting means that detects the three dimensional coordinates of at least two points on the real interface device within the real space; conversion means that converts the three dimensional coordinates of the real interface device within the real space into three dimensional coordinates within the virtual space, and displays the virtual interface device in the three dimensional coordinates within the virtual space on a display; operating means that displays movements of the virtual interface device on the display, the operating means causing the position detecting means to detect the three dimensional coordinates of the real interface device within the real space and the conversion means to determine the three dimensional coordinates of the virtual interface device within the virtual space at predetermined time intervals; intersection display control means that calculates a point in which an imaginary straight line that extends between the points on the real interface device intersects with the display and displays a marker thereon; and selection accepting means that determines whether or not the point lies on an object being displayed on the display, and allows the player to select the object if the point lies thereon.
