Abstract
An input processing device including a display screen and a pointing device for inputting corresponding 2-dimensional coordinates on the display screen. A 3-dimensional space is displayed on the display screen and the 2-dimensional coordinates inputted from the pointing device are detected. Next, shift amounts, per unit of time, of the detected 2-dimensional coordinates are calculated based on a predetermined calculation start condition. And the calculated shift amounts are converted to 3-dimensional coordinate shift amounts in the 3-dimensional space.
