Abstract
An after-image of a ball is displayed on traces of the ball so that each gamer recognizes in which direction and at which speed the shot ball flies. A real ball 30 really exists in a virtual space on a screen and flies from the left to the right in the figure. After-images 311 to 314 of the real ball 30 are displayed at the back of the real ball 30. The after-image 312 is displayed at a position of the real ball 30 before one interval (corresponding to 1/60 sec), the after-image 312 is displayed at a position of the real ball 30 before two intervals, the after-image 313 is displayed at a position of the real ball 30 before three intervals, and the after-image 314 is displayed at a position of the real ball 30 before four intervals. As the after-image is more apart from the real ball 30, the degree of transparency is higher.
