Virtual Reality, 3D Stereo Visualization, and Applications in Robotics

The use of 3D stereoscopic visualization may provide a user with higher comprehension of remote environments in tele-operation 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 tele-guide applications. This work investigates stereoscopic robot tele-guide under different conditions, including typical navigation scenarios and the use of synthetic and real images. This work also investigates how user performance may vary when employing different display technologies.
