Performance analysis in advanced tele-operation system based on introduction of danger-avoidance view

Research output: Contribution to journalArticle

Abstract

Unmanned construction machines are used after disasters. Compared with manned construction, time efficiency is lower because of incomplete visual information, communication delay, and lack of tactile experience. We have developed an autonomous camera control system to supply appropriate visual information. In order to let operator easy to avoid unexpected collision, we first introduce the frame for each viewport according to its contents. And then, we exchange the danger view with an overlook view. The purpose of this study is to attract operators’ attention to the danger area when there is a probable collision if operator won’t stop or change their action. Besides, we also want to reveal the relationship between gaze habit and performance. The experimental results conducted using our virtual reality simulator confirms that operator tends to watch danger view when it appears. In addition, work strategy may influence the danger avoidance and work time efficiency in opposite way.
