Navigating Buildings in "Desk-Top" Virtual Environments: Experimental Investigations Using Extended Navigational Experience
Participants learned the layout of large-scale "virtual buildings" through extended navigational experience, using "desk-top" (i.e., nonimmersive) virtual environments (VEs). Experiment 1 recreated aExpand

Navigating Large-Scale Virtual Environments: What Differences Occur Between Helmet-Mounted and Desk-Top Displays?
We used a helmet-mounted display (HMD) and a desk-top (monitor) display to learn the layouts of two large-scale virtual environments (VEs) through repeated, direct navigational experience. Expand
