This paper reports the positive effects of Augmented Reality visual cues on operator performance during end-effector controlled tele-operation using only camera views. Our solution is to overlay a color-coded coordinate system on the end-effector of the robot using AR techniques. This mapped and color-coded coordinate system is then directly mapped to similarly color-coded joysticks used for control of both position and orientation. The AR view along with mapped markings on the joystick give the user a clear notion of the effect of their joystick movements on the end-effector of the robot. All camera views display this registered dynamic overlay information on-demand. A preliminary test using fifteen subjects comparing control of performance with and without the coordinate mapping was performed by using a simple insertion task. Preliminary results indicate a significant reduction in distance, reversal errors and mental workload.
