Abstract

This thesis presents a novel approach for reducing the risk of cybersickness during virtual reality locomotion in a 3D environment through the use of somatosensory feedback. This project looks directly at existing theories regarding the cause of cybersickness and describes the processes taken to develop, test and measure the efficacy of a solution. The solution proposed by this thesis builds on the concept of sensory misalignment, where the body struggles understand its state due to conflicting sensory feedback and consequently generates negative health symptoms and discomfort. As such, the studies in this project attempt to emulate the feedback of real movement during VR locomotion by artificially generating the passive airflow undergone whilst moving.

To evaluate the work, two studies are carried out where users drive a simulated car around a virtual environment, which in one condition is accompanied by the solutions dynamic airflow emulation equipment. Primarily, studies examine for cybersickness, however on-going discussions in the research community regarding the nature of correlation between sickness and presence present interesting insights that this project could contribute to. The project’s pilot study failed to find conclusive results but provided a major amount of information about the correct strategies to use when investigating this exploratory area. A second study was far more successful, providing conclusive results showing that users felt less sickness and increased presence during the session supported by the somatic feedback extension. As such this work concludes suggesting somatosensory feedback has positive interactions with cybersickness, as per the project hypothesis regarding existing theories. Additionally, positive correlations with presence suggest somatic feedback can have an overall positive effect on VR locomotion.
