Reorient the Gazed Scene Towards the Center: Novel Virtual Turning Using Head and Gaze Motions and Blink

Novel virtual turning for stationary VR environments, accomplishing to reorient the gazed view towards the center, is proposed. Prompt reorientation during rapid head motion and blinking performed unnoticeable scene switching that achieved the seamless user experience, especially for the wide-angle turning. Whereas, continuous narrow-angle turning by horizontally rotating the virtual world corresponding to the face orientation achieved enhanced sense of reality. The proposal comprises a hybrid of these two turning schemes. Experiments using simulator sickness and presence questionnaires revealed that our methods achieved comparable or lower sickness scores and higher presence scores than conventional smooth and snap turns.
