Abstract: Immersive virtual environments (VEs) have potential in many application areas, but many complex VE systems exhibit usability and interaction problems. This is partly due to a lack of consideration or understanding of 3D interaction tasks and techniques. This paper proposes the systematic study of the design, evaluation, and application of VE interaction techniques. In this methodology, design and evaluation are based on a formal task analysis and categorization of techniques, using multiple performance measures. As a direct consequence of our use of this methodology, we also present a variety of novel designs and evaluation results with respect to interaction techniques for three common VE tasks.
