Abstract
The invention presents to a user a situation of the collision of an avatar against another object in a three-dimensional virtual space in an easy-to-understand manner. When the avatar is being navigated forward in the three-dimensional virtual space, if the avatar collides at its head node against a fixed object arranged in the three-dimensional virtual space (the object simulating a billboard, for example), an alert frame is displayed in the upper portion of the display area of a browser for displaying the three-dimensional virtual space. At the same time, an artificial collision sound is outputted. Thus, the alert frame corresponding to the colliding node is displayed and different collision sounds are outputted according to colliding nodes, so that the collision situation is presented to the user in an intuitively understandable manner.
