Abstract

The objective of this preliminary investigation was to quantify the effects of spatially displaced visual feedback on the operation of a camera-viewed remote manipulation task. Operators performed a remote manipulation task while exposed to the following different viewing conditions: direct view of the work site (baseline condition); normal camera view (zero-degree displacement); reversed camera view (180-degree lateral displacement); inverted/reversed camera view; and inverted camera view. The task completion performance times were statistically analyzed with a repeated measures analysis of variance and it was determined that there was statistical significance (p < 0.05) due to the main effect of the viewing conditions. A Newman-Keuls pairwise comparison test was then administered to the data and it was revealed that the performance times for the inverted camera view condition was significantly (p < 0.05) worse than all of the other viewing condition times.
