Overcoming delays and enhancing subjective comfort in virtual environments

by Pierre. Awaragi

Through the study of the effects of Virtual Reality (VR) on human subjects, scientists have determined that the main cause of discomfort while experiencing VR is the time lag between the head movements and its corresponding scene changes. The main purpose of this thesis is to study and to propose solutions to reduce VR effects. The proposed solution is an alternative controller based on a Proportional Derivative (PD) model. Compared with a simple Proportional Controller, the PD Controller offers several enhancements: namely, a larger bandwidth and a faster and more stable reaction time. The proposed controller will also reduce the physical side effects commonly experienced by users of Virtual Reality.
