VR System Lets Users Experience Walking in Another Person’s Shoes
TOYOHASHI, Japan, Oct. 31, 2019 — Researchers from the Toyohashi University of Technology have developed a virtual walking system. The system records a person walking and then replays it to another user through the oscillating optic flow and synchronous foot vibrations. The proposed recording system captures the walker’s oscillating optic flow with a pair of stereo cameras, and records the timings of feet striking the ground using four microphones embedded in the walker’s shoes. The system comprises a large-field-of-view...
