Adaptive Interpupillary Distance Adjustment for Stereoscopic 3D Visualization
Stereoscopic visualization creates illusions of depth through disparity between the images shown to left and right eyes of the viewer. While the stereoscopic visualization is widely adopted in immersive visualization systems to improve user experience, it can also cause visual discomfort if the stereoscopic viewing parameters are not adjusted appropriately. These parameters are usually manually adjusted based on human factors and empirical knowledge of the developer or even the user. However, scenes with dynamic change in scale and configuration can lead into continuous adjustment of these parameters while viewing. In this paper, we propose a method to adjust the interpupillary distance adaptively and automatically according to the configuration of the 3D scene, so that the visualized scene can maintain sufficient stereo effect while reducing visual discomfort.
