The Tradeoff of Frame Rate and Resolution in a Route Clearing Task: Implications for Human-Robot Interaction

摘要

The implications of bandwidth allocation are described for teleoperation in a military task that involved navigation, target detection, and target identification. Color versus grayscale imagery was manipulated. Participants themselves traded off resolution and frame rate settings. Participants minimized switching between resolution/frame rate settings and tended to use settings with high resolution/low frame rate. Courses completed with the highest resolution (and lowest frame rate) had the fastest target identification times, but no other differences were observed between settings. Color imagery offered advantages for overall course time and the time to identify a tank as friendly or enemy.
