Gaze adaptive convergence in stereo 3D applications

The accommodation vergence conflict is one of the the main sources for visual fatigue caused by stereo 3d. Special care has to be taken during content production in order to maintain a high quality of experience. However, the common approaches of doing so are not always viable and might come with certain disadvantages as well. In this paper, we therefore propose and analyze a method, which solves the accommodation vergence conflict. The basic idea is to constantly shift the point currently gazed upon into the display plane. This is done via convergence shifts of the stereoscopic imagery, which are known to be unperceivable if done slowly. The proposed method is based on gaze tracking, signal processing and disparity maps.
