Spatial orientation is more difficult to gain and retain, usually, when acting in synthetic and remote environments with reduced sensory input than in real environments. Previous studies showed that more cameras or different views can provide better performance in navigation, however, switching between egocentric and allocentric views often proved challenging. In the reported study, we used a treasure hunting game in a virtual environment experienced via a head-mounted display to explore whether egocentric viewpoints (egocentric bird’s eye view vs. map) and particularly a continuous viewpoint change from the bird’s eye view to the egocentric view on the ground improve performance in a new environment. In the first experiment the respective overview viewpoint (map, bird’s eye, continuous) could be accessed repeatedly. Participants used the continuous viewpoint change less often, presumably because it took more time than accessing the map or suddenly switching to the bird’s eye view. Despite less frequent support, performance was only slightly impaired in the continuous condition. In the second experiment where the respective overview was provided just once at the beginning of every trial, participants' performance reflected the expected advantage of the continuous change between viewpoints. Furthermore, with sudden switches, the egocentric bird’s eye view provided better support than the map view.
