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 sub-measures. Yet, some revealing observations were made regarding user behavior and interaction with the user interface.
