Interaction and evaluation of an augmented virtuality assistance system for teleoperated robots

This paper presents the main features and capabilities of a developed system based on augmented virtuality (AV), which is devoted to the assisted navigation of teleoperated robots. The goal is to provide users with a greater perception of the robot navigation environment that improves the accuracy in teleoperation tasks and reduces the workload required to drive. The developed system is a mixed-perspective exocentric display (ME3D) type. In order to assess the work carried out, a comparative study between the developed ME3D interface and a video-centric display (VC2D) has been conducted. To this end, we have implemented both interfaces on a real robot and performed an experiment with 16 subjects in a real scenario. As a result, we have obtained a high degree of acceptance in the use of the ME3D interface by participants.
