Using endpoints to judge alterations in self-produced trajectories in an immersive virtual environment

Abstract

McManus et al. [2011] studied a user's ability to judge errors in self-produced motion; more specifically, throwing. We now take the first step towards discriminating what cues subjects are using in order to make their judgments. The endpoint of the ball is one such cue; the restricted field of view (FOV) of the head mounted display (HMD) makes it difficult for users to view the complete trajectory of the ball, making the endpoint one of the more consistent cues available during the experiment. For the current study, we hid the trajectory of the ball and showed only the landing point of the ball.
