The Effect of Stereoscopic and Wide Field of View Conditions on Teleoperator Performance
Abstract
A study was performed to examine the effects of stereovision and wide field of view (FOV) and their possible interaction with teleoperator performance. The study used a 2x2 (narrow versus wide FOV and mono versus stereo vision) randomized between-subjects design. There were 24 subjects in all, 6 per cell, in conditions of monoscopic-narrow FOV, monoscopic-wide FOV, stereoscopic- narrow FOV, and stereoscopic-wide FOV. No significant interaction effects were found for time or error rate measures. However, analyses of variance (ANOVAs) yielded significant differences between mono and stereo vision for error rate (number of obstacles contacted) as well as reported motion sickness symptoms on the FOV dimension. Self-reported stress levels from pre- to post-run also yielded significant differences on the mono-stereo dimension. Chi-square analyses were performed on questionnaire data for condition preferences. A first chi-square analysis revealed significant findings of first choice of viewing condition, which was stereoscopic-wide FOV. Additionally, a second chi-square analysis of unique viewing conditions showed a significant effect of stereovision; it was the single most preferred viewing condition of all four.
