AB - For pedestrian navigation support, we report on how the feeling of being in control about receiving updates impacts navigation efficiency and user experience. In an exploratory field study, 24 participants navigated to previously unknown targets using a wristband which conveyed tactile information about targets  bearing. Information was either pulled by the user at times of her choosing via a simple arm gesture, or was pushed by the armband at a regular, preset interval. While the push mode resulted in higher efficiency, more users preferred actively pulling information, possibly as this afforded feeling more in control. Interestingly, mode preference was independent of individual navigation ability. Results suggest that properties of the specific navigation context should be used to determine whether an interface offers push or pull modes for navigation support.
