primary research relates to human spatial ability, including
spatial memory, perception, reference frames, landmark use, and
navigation. Because this work often includes the construction
and use of virtual environments for people to navigate within, I
also conduct applied research related to immersive virtual
reality and motion tracking. Most recently, this work has
involved developing Redirected Walking techniques (see Razzaque,
et al. 2005) to expand the navigavible area availaible for
am committed to interdisciplinary research and scholarship,
and I maintain active collaborations with colleagues in
several different departments and colleges at Miami
University, including computer science, education, business,
architecture, and psychology.
