Spatial Orientation in Virtual Reality with the Help of Continuous Updating between Different Viewpoints
Kurzfassung in englisch
This thesis is related to spatial orientation in virtual reality. Spatial orientation is important and essential in daily life but more difficult to gain and retain in synthetic and virtual environments with reduced sensory input than in real environments. Previous studies showed that more cameras or different viewpoints can provide better performance in navigation, however, switching between different viewpoints often proved challenging. In the current 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. Three conditions were designed as map, abrupt (switch directly from egocentric bird’s eye view to egocentric ground view) and continuous support systems. In the first experiment, participants were allowed to use different systems freely during navigation and instructed to find five targets in a particular sequence. Results showed that when participants decided to finish the task based on their memory, they exhibited the best performance. However, when they chose to use a support system, they exhibited equivalent performance with less use of the continuous system compared to the map or abrupt system. 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. In the continuous condition, the memorization interval was longer than in the map and abrupt conditions. In the third experiment, we improved experimental control by equalizing the duration of the memorization interval between conditions and inserted an additional task after the memorization interval and before the start of target search. Results showed similar performance in navigation in all three conditions. Indicators of strategy suggested that participants navigated less hesitantly and more efficiently in the continuous condition. To conclude, the results partly supported our hypothesis of a particular benefit from a continuous support system transitioning smoothly between an overview and the ego-perspective on the ground for spatial orientation and navigation.
