Thanks to a collegue at work (Tim), I just found out that all Canadian and US submitted Master's and Ph.D. thesis are public domain. Here is my thesis from 13 years ago!
Record number 000005165 Title Overcoming delays and enhancing subjective comfort in virtual environments Creator Awaragi, Pierre. Subject Health Sciences, Occupational Health and Safety. Subject Engineering, Biomedical. Subject Computer Science. Description.ABS 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. Description.ABS 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. Publisher McGill University Contributor Galiana, H. L.
