Abstract

Teleoperation requires a complex combination of the operator's cognitive, perceptual, and motor skills. Our experiment tested the ability of subjects to teleoperate a remote robot under different conditions of increasing sensory feedback. We also evaluated each operator's spatial perception skills using a battery of tests to understand the effect of spatial perception on the operator's ability to perform the teleoperation task. The experiment showed that the spatial ability of an operator-as reflected by a test battery of two spatial recognition and two spatial manipulation tests-was significantly correlated with the ability to teleoperate the robot through a maze. Surprisingly, providing different combinations of visual, auditory, and vibro-tactile feedback to the operator did not significantly change performance. However, there was an interaction between spatial ability and feedback condition that affected teleoperation performance.
