The Effects of System Fidelity for Virtual Reality Applications

Ryan McMahan

Assistant Professor

Department of Computer Science

ATEC Conference Room, ATC 1.606


Virtual reality (VR) has developed from Ivan Sutherland's inception of an "ultimate display" to a realized field of advanced technologies. Despite evidence supporting the use of VR for various benefits, the level of system fidelity required for such benefits is often unknown. Modern VR systems range from high-fidelity simulators that incorporate many technologies to lower-fidelity, desktop-based virtual environments. In order to identify the level of system fidelity required for certain beneficial uses, research has been conducted to better understand the effects of system fidelity on the user. In this talk, a series of experiments evaluating the effects of interaction fidelity and display fidelity will be presented. Future directions of system fidelity research will also be discussed.


Dr. Ryan P. McMahan is an Assistant Professor of Computer Science at the University of Texas at Dallas, where his research focuses on the effects of system fidelity for virtual reality (VR) applications. Using an immersive VR system comprised of a wireless head-mounted display (HMD), a real-time motion tracking system, and Wii Remotes as 3D input devices, his research determines the effects of system fidelity by varying components such as stereoscopy, field of view, and degrees of freedom for interactions. Currently, he is using this methodology to investigate the effects of fidelity on learning for VR training applications. Dr. McMahan received his Ph.D. in Computer Science in 2011 from Virginia Tech, where he also received his B.S. and M.S. in Computer Science in 2004 and 2007.

Note:  A limited number of box lunches will be available.
