Abstract
Vection is defined as the illusion of self-movement or the subjective experience of self-motion. Historically vection has been studied using subjective reporting methods. In this paper a Unity program is made to validate commercially available virtual reality headsets as an avenue for generation and objective measurement of vection. Experiments were conducted to validate the effectiveness of such an approach and to see if any differences could be measured when comparing different environments and novel ways of rotating the environment. The measurements detected the effects of vection but the differences in environment and ways of rotating the environment remained mostly inconclusive. It was observed that the rotation model which had the most intuitive connection to the subject’s own movements resulted in less deviation from the baseline. Summarily, the results of this paper suggest new ways of studying vection with modern virtual reality headsets.
