Mitigating Incorrect Perception of Distance in Virtual Reality through Personalized Rendering Manipulation

摘要

Viewers of virtual reality appear to have an incorrect sense of space when performing blind directed-action tasks, such as blind walking or blind throwing. It has been shown that various manipulations can influence this incorrect sense of space, and that the degree of misperception varies by person. It follows that one could measure the degree of misperception an individual experiences and generate some manipulation to correct for it, though it is not clear that correct behavior in a specific blind directed action task leads to correct behavior in all tasks in general. In this work, we evaluate the effectiveness of correcting perceived distance in virtual reality by first measuring individual perceived distance through blind throwing, then manipulating sense of space using a vertex shader to make things appear more or less distant, to a degree personalized to the individual's perceived distance. Two variants of the manipulation are explored. The effects of these personalized manipulations are first evaluated when performing the same blind throwing task used to calibrate the manipulation. Then, in order to observe the effects of the manipulation on dissimilar tasks, participants perform two perceptual matching tasks which allow full visual feedback as objects, or the participants themselves, move through space.
