Testbed Evaluation of Virtual Environment Interaction Techniques

摘要: As immersive virtual environment (VE) applications become more complex, it is clear that we need a firm understanding of the principles VE interaction. In particular, designers guidance in choosing three-dimensional interaction techniques. this paper, present systematic approach, testbed evaluation, for assessment techniques VEs. Testbed evaluation uses formal frameworks and experiments with multiple independent dependent variables to obtain wide range performance data We two experiments, covering common tasks travel object selection/manipulation. The results these allow us form general guidelines provide an empirical basis applications. Evaluation real-world system based on indicates approach can produce substantial improvements usability.
