Redirected walking is a technique used to extend the physical play space of a virtual reality implementation through manipulating the senses of the user. Techniques such as amplifying the rotation, the movement and tricking the user into correcting their path by subtly rotating. Such methods may turn a small play-space into a larger space, or a large space into a possibly infinite space. Such benefits are not without their cost. VR headsets can strain and cause unpleasant effects on the user by itself. Redirecting the user can further amplify this effect as the vestibular system, which helps the body maintain its balance through fluids passing through fine hairs in circular ducts will not be fooled unlike the eyes. Mismatches can cause a condition called virtual reality sickness, a set of symptoms similar to motion sickness, but arise when the sensory organs have conflicting stimuli. A Standardized approach is used through a simulator sickness questionnaire (SSQ) which has been modified for use on VR use-cases. The higher the redirection intensity, the greater the play-space can be extended, but the greater the sickness score. Factors such as redirection type and intensity are important to look at in order to determine how people react to them. The goal of this thesis is to understand what technical factors in a redirected walking system contribute to negative effects. The methodology chosen for the study is a mix of quantitative and qualitative methods alongside a gamified VR experience, while they are being exposed to redirection algorithms. There were no statistically significant differences, however the translation algorithm produced a 44.4% higher score than the lowest algorithm, and a 22% higher score than the second highest algorithm. All intensity level showed a positive trend. Higher scales lead to higher sickness scores. The curvature algorithm shows potential considering the growth per scale, which represents the radius of a circle for use in smaller spaces. No conclusion was able to be drawn due to lack of statistical significance.
