Scalability of Robotic Displays: Display Size Investigation

Abstract

This study was an investigation of the effect of camera view display sizes on robotic tele-operation control performance in a realistic context. It took place at Fort Benning, Georgia, and used Soldiers from the Officer Candidate School. After training in the operation of the TALON robot system, each Soldier completed exercises using four different display sizes that were chosen to match the size and resolution of displays that might be used by dismounted Soldiers for other purposes in the near future. The terrain, targets, and hazards were counterbalanced along with the display size to control for the effect of learning. Display size and usability for robotic driving were evaluated, based on objective performance data, data collector observations, and Soldier questionnaires.
