Effects of mobile map orientation and tactile feedback on navigation speed and situation awareness

Mobile information systems aid first responders in their tasks. Support is often based on mobile maps. People have different preferences for map orientations (heading-up or north-up), but map orientations also have different advantages and disadvantages. In general north-up maps are good for building up situation awareness and heading-up maps are better for navigational tasks. Because of heavily loaded visual modalities, we expect that tactile waypoint information can enhance navigation speed and situation awareness. In this paper we describe an experiment conducted in a synthetic task environment, in which we examined the effect of heading-up and north-up displays on search and rescue performance of first responders, and if adding the tactile display improves performance.
