Outline of Final Research Achievements

When we play three-dimensional computer graphics (3DCG) video games of third-person point of view, we can usually control both an avatar and a camera. There are some enemy characters in the CG game world, and we often lose contact with an enemy after the avatar collides with it. In this paper, we propose a camera control system that the view point makes a half turn in a horizontal direction after the avatar collides with the enemy. The camera shows both of the avatar and the enemy from the backside of the avatar. In addition, we propose a representation technique that obstacles make translucent to avoid occlusion when the avatar collides with the enemy. As a result of subjective evaluation experiment, it was shown that the visual effects of the proposed techniques useful to enhance affective impressions. Therefore, we think that the proposed techniques contribute to qualities of action video games.
