ABSTRACT
Researchers at the Computer Graphics and User Interfaces Lab of Columbia University found that the effects of virtual reality (VR) sickness were reduced by controlling the range of visibility, based on how much the user is moving around in the virtual world. This chapter looks at one way to implement a similar system that will display an image in front of the camera, scaled to dynamically adjust visual range as a target GameObject moves around a Scene. Sufferers of VR sickness also seem to get along better with a cockpit around them, and it may be down to the same principal of a virtual nose, having a static reference point. VR sickness symptoms may be triggered by the character stopping in place but the camera continuing to move.
