Stereo vision and acuity tests within a virtual reality set-up

The provision of stereo images to facilitate depth perception by stereopsis is one key aspect of many Virtual Reality installations and there are many technical approaches to do so. However, differences in visual capabilities of the user and technical limitations of a specific set-up might restrict the spatial range in which stereopsis can be facilitated. In this paper, we transfer an existent test for stereo vision from the real world to a virtual environment and extend it to measure stereo acuity.
