Camera Time Warp: Compensating Latency in Video See-Through Head-Mounted-Displays for Reduced Cybersickness Effects

摘要

Camera Time Warp or “CamWarp” is an extension of current reprojection techniques for video see-through augmented reality (AR), which significantly reduces the registration error between captured real-world videos and rendered virtual images. Experiment participants were asked to report discomfort while moving their head in a Fitts' Law inspired pattern. Results suggest that CamWarp can reduce discomfort and cybersickness symptoms for all tested camera configurations. In a second experiment participants were asked to move physical objects on a projected path as quickly and precisely as possible. CamWarp had a positive effect on speed and accuracy.
