Abstract
A pursuit tracking task in three-dimensional space was studied in order to assess the impact of depth perception on human operator performance in manual control. Performance scores and frequency response data were collected and analyzed for three modes of display as defined by the angular relationship between the human operator's line-of-sight and the line segment representing the tracking error. When depth perception had to be completely relied upon, a significant decrement in performance occurred and was accompanied by the introduction of phase lags in the human operator's response.
