Stereo vision vs. projected shadows in performance evaluation of teleoperated systems

Virtual environments used as human machine interface in teleoperated systems can be substantially improved, by adding resources devoted to increase 3D perception of the virtual scene. Monoscopic displays are a way of optimizing resources because they show better quality images and they are lower cost in computing time than other graphic systems. In this paper, we demonstrate that monoscopic displays can be competitive versus stereo vision in performance, by adding projected shadows to the first
