Virtual Reality

Description: 

Virtual reality (VR) is a term that applies to computer-simulated environments that can simulate physical presence in places in the real world, as well as in imaginary worlds. Most current virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays. Virtual reality is often used to describe a wide variety of applications commonly associated with immersive, highly visual, 3D environments.

The “Silk Cursor”: investigating Transparency for 3D Target Acquisition

This study investigates dynamic 3D target acquisition. The focus is on the relative effect of specific perceptual cues. A novel technique is introduced and we report on an experiment that evaluates its effectiveness. There are two aspects to the new technique. First, in contrast to normal practice, the tracking symbol is a volume rather than a point. Second, the surface of this volume is semi-transparent, thereby affording occlusion cues during target acquisition. The experiment shows that the volume/occlusion cues were effective in both monocular and stereoscopic conditions.

This study investigates the use of a 2D cursor presented to one eye for target selection in Fish Tank VR and other stereo environments. It is argued that 2D selection of 3D objects should be less difficult than 3D selection. Vision research concerning binocular rivalry and the tendency we have to project images onto surfaces suggests that this mode of viewing
