We describe a desktop virtual reality system targeted at 3D puzzle assembly. The results of the evaluation show that all novices could successfully complete the puzzle within an average of about six minutes, while experts took about two minutes.

This paper evaluates two different interfaces for navigation in a 3D environment. The first is a 'Click-to-Move' style interface that involves using a mouse. The second is a gaming style interface that uses both mouse and keyboard (i.e. the 'WASD' keys) for view direction and movement respectively. In the user study, participants were asked to navigate a supermarket environment and collect a specific subset of items. Results revealed significant differences only for some of the submeasures. Yet, some revealing observations were made regarding user behavior and interaction with the user interface.3d navigation, 3d virtual environments, gamer interface, supermarket simulation, user studies.
