Abstract
The virtual window display is a hybrid of the head-coupled, helmet-mounted display and the fixed CRT mounted on a tabletop. Moving the CRTs from the operator''s head retains the benefits of motion parallax while providing higher quality color images, greater comfort and fewer restrictions on the operator''s view of the control site. A prototype virtual window display was constructed with direct mechanical linkage to servo camera movements to the operator''s head motions. This apparatus was used to compare remote performance with and without motion parallax, paired with either stereoscopic or monoscopic views. Mean stereoacuity and depth scaling responses for six observers of a Howard-Dolman apparatus showed improved performance when motion parallax accompanied monoscopic, but not stereoscopic view. Mean performance times for six observers retrieving objects from a wire maze show similar, though not significant, improvement when motion parallax accompanies monoscopic view. Observers report that manipulator requirements for hand steadiness reduce the opportunity to get depth information from head movements. The use of motion parallax information in a monoscopic virtual window display can improve teleoperator performance.
