Software Techniques to Reduce Cybersickness Among Users of Immersive Virtual Reality Environments

Abstract

The virtual worlds are photorealistic, the users have difficulty distinguishing the reality and virtuality. The high degree of realism of artificial virtual worlds results in deep immersion in virtual environments. The users immerse themselves in the virtual world. The immersion may, however, provoke different undesirable side-effects. The symptoms of motion sickness occurring mainly in transport means (buses, planes, ships, etc.) are also observed among users of virtual worlds where the users usually view moving scenes while they remain physically stationary. In the case of virtual reality it is called cybersickness. The paper presents software techniques to reduce cybersickness among the users of immersive virtual reality environments and analyses the results of experiments showing their efficiency and their impact on the users of virtual worlds.
