All are welcome to attend.

The title of his thesis is: The Geometric Field of View and Speed Perception in a Driving Simulator

Abstract:

Particularly in the health and rehabilitation sector where cost and space are constraints, practitioners are using smaller driving simulators.  Because these small-footprint driving simulators have a limited projected field of view (PFOV) it is desirable to extend the virtual or geometric field of view (GFOV) beyond that natively afforded by the PFOV.   Changing the PFOV/GFOV ratio has been shown to alter perceived speed.  In order for driving simulation to produce realistic experiences, drivers’ perception of speed should correspond with real world experiences.  The purpose of the current research was to better understand the relationship between speed perception and the GFOV/PFOV ratio in a way that would be useful to simulation practitioners using a small-footprint driving simulator.  Participants performed a speed matching task using different six GFOV conditions while the PFOV was held constant.  Three target speeds were presented in appropriate simulated environments: 25mph in a residential area, 45mph in a commercial area, and 65mph on a freeway.  Perceived speed was found to increase with larger GFOVs.  However, no GFOV tested produced accurate speed perception; on average, all participants underestimated their speeds using all GFOVs.  A regression was used to estimate at which GFOV error in speed production would approach zero.  Subjective data collected regarding participant strategy, perceived accuracy, and their awareness of different GFOV conditions are also discussed.
