We use pedestrian collision detection and judgment performance to evaluate the impact of various factors on visual confusion and rivalry in field expansion. We have developed a VR walking simulator scenario using our driving simulator and tested it with field expansion visual aids. An open space VR walking environment (walk in the park) is simulated using our driving simulator, which provides a 225° FoV. The simulated pedestrians initially appear at bearing angles from the subject of 10°-45°. They are either on a collision course with the patient (time-to-collision 6s) or designed to pass behind or in front of the patient. The speeds of both patient and pedestrian are fixed (though different) for each event. Patients press the horn when they first detect the pedestrian. Both the detection rate and response time are recorded.

We develop a new VR walking simulator using the Unity game engine on HMD. The new walking simulator will present a crowded airport terminal or shopping mall scene with multiple pedestrians in each scene. The subject will be asked to look at the lead person. Multiple pedestrians will be continuously present appearing at various bearing angles and courses.
