Two experiments examine the abilities of 10 subjects to visualize directions shown on a perspective display. Subjects indicated their perceived directions by adjusting a head-mounted cursor to correspond to the direction depicted on the display. This task is required of telerobotic operators who use map-like pictures of their workspace to determine the direction of objects seen by direct view. Results show significant open-loop, judgement biases that may be composed of errors arising from misinterpretation of the map geometry and overestimation of gaze direction.
