TL;DR: In this article, Thorndyke et al. investigated the effect of localized landmarks on the accuracy of route finding in a virtual building and found that participants were more accurate in their route finding when familiar objects were used as landmarks than when no landmarks were used.

TL;DR: Behavioral data indicates that both translational and rotational body-based information are required to accurately update one's position during navigation, and participants who walked tended to avoid obstacles, even though collision detection was not implemented and feedback not provided.

TL;DR: Behavioral analyses showed that participants took advantage of the natural, head-tracked interface provided by the HMD in ways that included looking around more often while traveling through the VEs, and spending less time stationary in the VE while choosing a direction in which to travel.

TL;DR: The experiments show that locomotion devices such as linear treadmills would bring substantial benefits to virtual environment applications where large spaces are navigated, and theories of human navigation need to reconsider the contribution made by body-based information, and distinguish between environmental scale and extent.

TL;DR: The ‘blame’ for many such accidents may be due to a perceptual quirk: it appears that drivers think they are driving far more slowly in foggy conditions, and therefore increase their speed.
