In the ideal orthostereoscopic viewing system the geometric relationship between the manipulator arm and cameras is designed to product a close correspondence between the operator's actual and imaged hand-to-eye position. This correspondence often cannot be maintained because of the physical design constraints of manipulator, cameras, or mounting structure. Cameras mounted in a non-corresponding position, in relation to the operator's hand- to-eye position, create a visual-motor mismatch. In this study the rapid sequential positioning (RSP) task is used to measure manipulator performance under two levels of visual-motor correspondence. Performance was measured by (1) taking a pure perceptual measure, (2) taking total time to complete a task, (3) measuring various types of errors, and (4) number of perfect and near perfect task completions. One group viewed a scene in which there was a visual-motor correspondence and the other group viewed a noncorresponding scene, in which the cameras were shifted 30 degrees clockwise from the orthoscopic position. Each group performs the RSP task under four visual conditions. Those four visual conditions are monoscopic stationary, monoscopic with motion parallax, stereo stationary, and stereo with motion parallax. The performance of groups under different views was compared to determine the effect of visual-motor noncorrespondence.
