Tele-operated driving enables industrial operators to control heavy machinery remotely. By doing so, they could work in improved and safe workplaces. However, some challenges need to be investigated while presenting visual information from on-site scenes for operators sitting at a distance in a remote site. This paper discusses the impact of video quality (spatial resolution), field of view, and latency on users’ depth perception, experience, and performance in a lab-based tele-operated application. We performed user experience evaluation experiments to study these impacts. Overall, the user experience and comfort decrease while the users’ performance error increases with an increase in the glass-to-glass latency. The user comfort reduces, and the user performance error increases with reduced video quality (spatial resolution).
