The document evaluates different motion constraints for aiding wayfinding in 3D virtual environments. It found that (1) free navigation performed better in an immersive CAVE environment while spring-based guidance on desktop performed significantly better, (2) navigation guidance was more efficient than free flight, and (3) navigation guidance had a higher impact on wayfinding for desktop users than CAVE users. The study suggests that removing some freedom in 3D navigation through guided tours can actually improve cognitive map building and wayfinding.
