Abstract
Effective interaction techniques are critical for productive use of virtual environments for business, manufacturing, and training. This thesis addresses the need to match the dimensionality of tasks performed in a virtual environment to the dimensionality of the techniques used to perform the tasks. In order to demonstrate the performance benefits of matching the dimensionality of task and technique, an experiment was conducted in which twenty-seven subjects were asked to perform a series of two and three-dimensional tasks. Subjects were required to perform all tasks using only three-dimensional techniques, then only two-dimensional techniques, and finally a combination of both techniques. The results clearly showed that matching the dimensionality of the task to the dimensionality of the interaction technique achieved the best performance in a virtual environment. Of 27 subjects, 90% preferred to use a technique whose dimensionality matched the requirements of the task. More importantly, 100% demonstrated improved performance when the dimensionality of task and technique matched
