Depth cue interaction in telepresence and simulated telemanipulation

We examined the contribution of two important depth cues, occlusion and disparity, on the performance of a simulated telerobotic task. We have simulated a three-axis tracking task that is viewed under four different levels of realism. We hoped to determine if the combined presentation of the depth cues has a more beneficial effect on performance than either depth cue presented singularly. Results showed similar performance improvements with the presentation of occlusion or disparity individually. When both cues were present together, a somewhat larger performance improvement was measured.
