Effects of scale change on distance perception in virtual environments

We conducted two experiments to investigate effects of scale changes on distance perception in virtual environments. In both experiments, participants first made distance estimates with feedback in a virtual tunnel (adaptation) and then made distance estimates without feedback in a differently sized environment (test). We examined two types of scale changes. In the “Tunnel Scaled” conditions, only the size of the tunnel changed from adaptation to test. In the “All Scaled” conditions, both the tunnel and target sizes changed from adaptation to test, along with the distance between the targets. Both experiments were carried out in an HMD. In the first experiment, participants made distance estimates by moving to targets via a joystick. In the “All Scaled” condition, participants overshot relative to adaptation when going from a large to a small environment, and they undershot relative to adaptation when going from a small to a large environment. We found almost no effects ...
