Abstract

In direct-projected augmented reality, different position of user requires different projection on 3-D display surface. The problem is caused by the difference between the direction of projector-to-object and the direction of user-to-object. In this paper, it is demonstrated that the graphical contents are properly pre-warped according to user's viewpoint and projected onto 3-D display surface without geometric distortion.
