Abstract
We present two experiments examining the impact of navigation techniques on users ’ navigation performance and spatial memory in a zoomable user interface (ZUI). The first experiment with 24 participants compared the effect of egocentric body movements with traditional multi-touch navigation. The results indicate a 47 % decrease in path lengths and a 34 % decrease in task time in favor of egocentric navigation, but no significant effect on users’ spatial memory immediately after a navigation task. However, an additional second experiment with 8 participants revealed such a significant increase in performance of long-term spatial memory: The results of a recall task administered after a 15-minute distractor task indicate a significant advantage of 27 % for egocentric body movements in spatial memory. Furthermore, a questionnaire about the subjects ’ workload revealed that the physical demand of the egocentric navigation was significantly higher but there was less mental demand.
