Evaluation of Movement Control Techniques for Immersive Virtual Environments
Douglas A. Bowman, David Koller, Larry F. Hodges · 1996
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. INTRODUCTION The field of virtual environments (VEs) in general, and the area of VE user interfaces specifically has not been the focus of a great deal of user testin...
