Baseline Factors for Raycasting Selection

Selection is a common task in Virtual Environment (VE) interfaces. Several techniques have been created to perform the task and two testbed studies have performed comparison studies between the techniques. In this study focusing on Raycasting selection, we created an understanding of the known factors influencing selection and create a model of selection time and angular error. We found evidence that users try to maximize visual feedback by purposefully creating angular error and developed an argument for a possible visual feedback parameter to explain behavior across multiple studies.
