Interaction Techniques for Immersive Virtual Environments: Design, Evaluation, and Application
Doug A. Bowman · 1998
Immersive virtual environments (VEs) have potential in many application areas, but most successful VE systems exhibit little interactivity. This is largely due to a lack of consideration or understanding of 3D interaction tasks and techniques. This work proposes the systematic study of design, evaluation, and application of VE interaction techniques. Design and evaluation are based on a formal task analysis and categorization of techniques, using multiple performance measures. This methodology will be tested by applying the results to a complex VE application allowing users to modify the design of a space while immersed within it. 1 INTRODUCTION Virtual Environments (VEs) offer a new human-computer interaction paradigm in which users are no longer simply external observers of images on a computer screen but are active participants with a computergenerated three-dimensional virtual world. Proposed and developing applications include design, visualization, education, and both training ...
