Abstract:
We present a categorization of techniques for first-person movement or
travel through immersive virtual environments, as well as a framework
for evaluating the quality of different techniques for specific virtual
environment tasks. We conduct three quantitative experiments within this
framework: a comparison of different techniques for moving directly to a
target object varying in size and distance, a comparison of different
techniques for moving relative to a reference object, and a comparison of
different motion techniques and their resulting sense of
"disorientation" in the user. Results indicate that "pointing" techniques
are often advantageous relative to "gaze-directed" steering techniques,
and that motion techniques which instantly teleport users to new
locations are correlated with increased user disorientation.
