An investigation has been carried out on the effects of skill acquisition of the type of closed circuit video system being used in a teleoperation system. Two experiments were performed, using a mobile explosive ordnance disposal robot equipped with a switchable monoscopic/stereoscopic video system. One experiment comprised a simple, repetitive approach-and-touch task. The other involved a Fitts' law type of speed/accuracy tradeoff task. In both experiments, subjects' learning data were recorded. The results are discussed in terms of relative performance of stereoscopic versus monoscopic viewing, as a function of repetition number and of task difficulty. An important result is that for highly repetitive tasks it is less demanding to perform the task using a stereoscopic display than using a monoscopic display at all levels of experience.
