Abstract

When exploring environments remotely, the knowledge of the teleoperated vehicle location is a key element for operators' situational awareness. Given visual information provided by the ROV, we aimed at finding the best combination between the maps used by operators, visual feedbacks provided by the ROV and the displays to show the previous information. In our system, teleoperators use 2D top-view or 3D immersive representation of the remote world as maps. From the remote site, they receive a live video stream provided by a remotely controlled pan-tilt camera. Maps and video streams are displayed on PC screens or HMD's. We give and we discuss here, the results of the performed experiments. As expected, the 3D maps give more accurate estimation but are time consuming. On the other hand, we found that the use of simple PC-screens leads to better results than HMDs.
