Visuo-Haptic Redirected Walking

URL

We propose a method for improving the effects of manipulation in redirected walking (RDW) by using haptic cues, particularly for the discrimination of path curvature. We develop an RDW system, which displays a visual representation of a flat wall and users virtually walk straight along it although, in reality, users walk along a convex surface wall with touching it. Using this system, we conduct an experiment, and the results show that our method reduced the amount of perceived curvature in RDW as compared to an only visual method.
