ABSTRACT:
A manipulation target such as a lever or button is displayed in a three-dimensional virtual space using three-dimensional computer graphics. The positions of a thumb and an index finger are detected. A manipulation instruction is interpreted, using interpretation rules described on the basis of a relationship between the detected positions and the thumb and the index finger and the three-dimensional coordinates of a display device.
