Abstract
An important and troublesome problem with current virtual environment (VE) technology is the tendency for some users to exhibit symptoms that parallel symptoms of classical motion sickness both during and after the VE experience. This type of sickness, cybersickness, is distinct from motion sickness in that the user is often stationary but has a compelling sense of self motion through moving visual imagery. Unfortunately, there are many factors that can cause cybersickness and there is no foolproof method for eliminating the problem. In this paper, I discuss a number of the primary factors that contribute to the cause of cybersickness, describe three conflicting cybersickness theories that have been postulated, and discuss some possible methods for reducing cybersickness in VEs.

Software Techniques to Reduce Cybersickness Among Users of Immersive Virtual Reality Environments
Intelligent Information and Database SystemsAbstractThe 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 ...
Experimenting novel virtual-reality immersion strategy to alleviate cybersickness
VRST '18: Proceedings of the 24th ACM Symposium on Virtual Reality Software and TechnologyCybersickness, related to virtual-reality (VR) using head-mounted devices (HMD), is also known as motion sickness in VR environment. Researchers and developers have been working to find an appropriate technological facility to alleviate this feeling of ...
