Dynamic view parameter adjustment can reduce visual fatigue issues in stereo displays. In a multi-scale virtual environment, which has geometric details ranging over several orders of magnitude, these adjustments are particularly important. We evaluate how two adjustment techniques interact with 7 degree-of-freedom navigation in desktop VR and a CAVE. The travel task has two stages, an initial targeted zoom and detailed geometric inspection. The results show benefits of the adjustments both for reducing fusion problems and for task completion time, but only in certain condition combinations. Peculiar view configuration examples demonstrate the difficulty of creating robust adjustment rules.
