Immersion visuelle tridimensionnelle haute performance par suivi du mouvement des yeux

Abstract : Simulators are more and more used in industry because they help for making and testing objects. Like in other domains, simulators use stereoscopic screen to get closer natural vision and artificial vision. However, stereoscopy create some physiological problems like vergence-accommodation conflict. This conflict is one of the main cause of visual strain while viewing stereoscopic contents. In a first part, we will see some methods to reduce visual fatigue due to vergence-accommodation conflict. Then, we will propose, test and validate a new method: a blur in peripheral vision. This treatment reduce eye strain. In addition, we found out that the smaller the sharp area is, the more effective the treatment is. In the second part, we will focus on the shape perception in stereoscopic vision and how to improve it. The main contribution will be to take into account the user’s gaze point in the rendering process to reproduce the effect of the gaze direction in natural vision and improve the perception of the virtual environment. This camera convergence create deformations – called vertical parallaxes – on the screen in peripheral vision. This new method improve shape perception if objects are located close to the user.
