Effect of stereographic + stereovideo 'tether' enhancement for a peg-in-hole task

A basic three-dimensional line enhancement (tether) is investigated in real and stereoscopic graphic (SG) (virtual) forms and with monoscopic and stereoscopic displays, within the context of a peg-in-hole task. Results from two experiments indicated that a tether provided useful spatial information to the operator viewing a stereoscopic video (SV) display but not a standard (monoscopic) display: subjects made fewer errors and were more consistent. Performance with the virtual tether enhancement was superior to performance with a real tether. The results suggest that, given a properly calibrated system, people should be able to make practical use of SG overlays on SV in carrying out in-the-loop teleoperations.<<ETX>>
