  Abstract

In immersive virtual reality system, since virtual worlds do not supply users with sufficient spatial information as real world does, the users frequently experience clumsiness and roughness while manipulating virtual objects. To overcome this problem, we propose Visual Guider in this paper as a tool for enhancing user''s visual space perception in immersive virtual worlds. The Visual Guider aids users to recognize exocentric distances between different scene points and egocentric distances from the observation point to other points in the scene fast and precisely. Its concept is imported fro the rectangular grids frequently used in two-dimensional windows applications. We applied the proposed technique to an experimental virtual space implemented in CAVE™-like system and tested its effectiveness while users grasp and move virtual objects.
