PDF: The Effect of Hanger Reflex on Virtual Reality Redirected Walking

Abstract

One of the major challenges in virtual reality (VR) is to create a perception of a large virtual space within a limited physical space. Here, we explore the effect of haptic-based navigation by Hanger Reflex (HR) on the perception in redirected walking (RDW) with visual manipulation. Seven individuals walked along a straight path in VR while, unbeknown to them, the visual scene was rotated with a curvature gain of π/36, forcing them to walk in a circular path in real space. HR rotation (in the left, right, and neutral direction) was induced by a wearable haptic device during each of the walking trials, and they reported their perceived walking direction and effort to walk along the path on visual analog scale. Experiment results showed that HR can influence the perception in RDW, but the effects may be complex and therefore require further investigation.
