COMM

Participants were instructed to reproduce a previously observed distance by travelling passively at a constant velocity into straight textured tunnels in a CAVE. The diameter of the tunnel into which participants travelled and the egocentric distance to be reproduced were manipulated. Participants' distance perception was sensitive to the tunnel's scale, distance being overestimated with the tunnel's diameter increase and underestimated with the tunnel's diameter decrease.
