3D visualization technologies for teleguided robots

The use of 3D stereoscopic visualization may provide a user with higher comprehension of remote environments in teleoperation when compared to 2D viewing. Works in the literature have demonstrated how stereo vision contributes to improve perception of some depth cues often for abstract tasks, while little can be found about the advantages of stereoscopic visualization in mobile robot teleguide applications. This work investigates stereoscopic robot teleguide under different conditions, including typical navigation scenarios and the use of synthetic and real images. This work also inves-tigates how user performance may vary when employing different display technologies. Results from a set of test trials ran on five vir-tual reality systems emphasized few aspects which represent a base for further investigation as well as a guide when designing specific systems for telepresence.
