Assessment of Stereoscopic Display Systems for Assisting in Route Clearance Manipulation Planning Tasks

Report No. ARL-TR-4195

Abstract: This study was conducted to objectively compare how the use of a three-dimensional (3-D) or two-dimensional (2-D) visual display affects manipulation planning performance in a spatial perception task relevant to the operation of the Buffalo vehicle manipulator arm. Portions of the results are also generalizable to any tele-operated precision manipulation task. The task evaluated involves judging the position of the Buffalo arm relative to targets and obstacles as seen in the visual display from the arm camera. Thirty-two Soldiers trained to use the route clearance vehicle participated in this study at Fort Leonard Wood, Missouri, during the summer of 2006. Significant planning performance benefits were found when the 3-D visual display was used as opposed to the 2-D display. A significant correlation between subjective confidence ratings and objective performance was found with 3-D displays but not with 2-D displays. Most participants indicated that they preferred using the 3-D display instead of the 2-D display.
