Most pointing techniques for 3D selection in spatially immersive virtual environments rely on a ray originating at the user's hand and controlled by the hand orientation. However, mismatches between visible objects (those appearing unoccluded from the user's eye position) and selectable objects (those appearing unoccluded from the user's hand position) could hinder selection performance. The authors propose a new device-ray mapping, Ray Casting from the Eye (RCE), to overcome this problem. In a controlled experiment involving selection tasks with complex 3D scenes, RCE clearly outperformed ray casting in terms of speed and accuracy. This article is part of a special issue on 3D user interfaces.
