Teleroboticists have long argued that improved control and display performance would enhance telepresence and, thereby, telemanipulator performance. This study measured the impact of the DTI autostereo visual display system upon telemanipulation capacity, operator perceptions of system controllability, and perceived fatigue and discomfort, when faced with a wide range of movement amplitudes and end point accuracy in low and moderate variations in illumination levels. With introduction of stereovision, remote manipulation performance materially improved. Improvements were found only in the positioning phases of manipulations; not in rapid ballistic move elements. Improvements were found regardless of the level of illumination present at the remote work site in this study.
