LAND VEHICLE TELEOPERATION UNDER CONDITIONS OF REDUCED VIDEO RESOLUTION

Teleoperation of land vehicles was studied to investigate the effects of both spatial and temporal video resolution on the ability of the operator to effectively control the vehicle. Teleoperation extends part of a human operator's presence into remote or hazardous areas, and the predominant form of sensory feedback is that of vision. The quality of the transmitted video information has a significant effect on the operator's confidence and ability to effectively control the vehicle. Experiments were constructed to allow subjective evaluation of the lower limits of video quality necessary for degraded, yet effective, Teleoperation. Subjects were asked to teleoperate a remote vehicle under varying conditions to degraded spatial and temporal resolution, and their comments were recorded along with the video driving scenes during teleoperation. Subjective assessments and teleoperation test data suggest the possibility of reducing the required video bandwidth for teleoperation by a factor of 28:1 over normal video standards.
