Paper Abstract

Most off-the-shelf immersive virtual environment (IVE) systems do not provide adequate depth cues to allow quick and accurate manual interactions with virtual objects. Studies of teleoperation tasks show that using stereoscopic displays improves performance, especially in situations with increased scene complexity and decreased object visibility. However, many aspects of these studies prevent generalization of the results to IVE systems. Further, the additional costs of high-resolution stereoscopic displays preclude their widespread use in business and educational settings. In this paper, the effects of various visual and auditory display enhancements were evaluated to determine whether they may replace depth peg in one location and placed it on a virtual target in another location, provided a common test situation in which to compare various enhancements. Participants wore a commercial head-mounted display and spatial trackers on the head and hand. Results indicated conditions under which visual and auditory enhancements to monocular displays resulted in performance that was not different from using stereoscopic displays. Theoretical foundations for the findings and implications of the results for other tasks in VEs are discussed.
