Interfaçage visuel stéréoscopique : diminution de la fatigue visuelle et caractérisation de la perception des formes

Abstract : Through Virtual Reality techniques, it is possible to create virtual objects entirely designed using computer programs. The greatest claimed advantage is that designers can modify virtual objects as much as they wish. When an object suits them, they can then decide to build a real object, using the virtual object as a template. But two important questions remain. The first one is “will the virtual object they see on the screen really correspond to the real object created?” In other words, the issue is whether immersive design (and especially stereoscopic vision) can create a perception of a virtual object which corresponds closely enough to the real object later created from the virtual object. The second one concerns the eyes strain. In some instances, exposure to stereoscopic immersion techniques can be lengthy, and eye strain sets in. We propose a method for reducing eye strain induced by stereoscopic vision. After reviewing sources of eye strain linked to stereoscopic vision, we will focus on one of these sources: images with high frequencies contents associated with large disparities (high level of relief). We will put forward an algorithm for removing the irritating high frequencies in high disparity zones (i.e. for virtual objects appearing far from the real screen level). We will elaborate on our testing protocol to establish that our processing reduces eye strain caused by stereoscopic vision, both objectively and subjectively. We will subsequently quantify the positive effects of our algorithm on the relief of eye strain
