“…There has also been previous work on adaptively adjusting stereo visualization parameters at production time according to the screen sizes [9][11] or the intended region of interest in depth space [14]. However, to our best knowledge, there has been no previous work adjusting IPD at runtime adaptively according to the scene configuration (especially, relative distance between the scene and the user's viewpoint).…”

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.

“…One of the main factors that cause visual discomfort in stereoscopic visualization is extreme or incorrect disparity between the views shown to the left and right eyes of the user [9]. The image disparity results from visualizing the 3D scene from two different perspectives corresponding to each eye of the user.…”

We propose a novel method to avoid stereo window violations at screen borders.These occur for objects in front of the zero parallax plane, which appear in front of the (physical) screen, and that are clipped for one eye while still being visible for the other eye. This contradicts other stereo cues, particularly disparity, potentially resulting in eye strain and simulator sickness. In interactive and dynamic virtual environments, where the user controls the camera, for example, via head tracking, it is impossible to avoid stereo window violations completely. We propose Dynparity, a novel rendering method to eliminate the conflict between clipping and negative disparity, by introducing a nonuniform stereoscopic projection. For each vertex in front of the zero parallax plane, we compute the stereoscopic projection such that the parallax approaches zero toward the edge of the screen. Our approach works entirely on the GPU in real-time and can be easily included in modern game engines. We conducted a user study comparing our method to the standard stereo projection on a large-screen stereo wall with head tracking. Our results show significantly reduced simulator sickness when using Dynparity compared to the standard stereo rendering.
