I present a framework for examining the interaction of different locomotion interfaces with visual information and their effect on navigation decisions in virtual environments and present an experiment using this framework. For each trial in the experiment, participants moved towards a goal in a virtual room along one of two paths which differed visually, using either a joystick or a walking-in-place metaphor. Walking-in-place locomotion interfaces tended to be more natural under some visual conditions, as reflected in an increased likelihood of selecting the ecologically preferred path. The novel framework provides a way of studying factors in perceptual decision-making and demonstrates the effect of interface on natural behaviour

Assuming that more natural interfaces produce more natural locomotor behaviors, we propose a framework for assessing the quality of a locomotion interface. Using this framework, we studied the interaction of different locomotion interfaces with visual information on wayfinding decisions in a virtual environment. We compared decisions made using a dual joystick gamepad with a walking-in-place metaphor. Paths presented on a given trial differed visually in one of the following aspects: (a) slope, (b) friction, (c) texture, and (d) width. In this experiment, choices made with the walking-in-place interface more closely matched visual conditions which would minimize energy expenditure or physical risk in the natural world. We provide some observations that would further va...
