But for the blind or visually impaired traditional maps are not accessible. In our previous work, we developed the “Auditory Map” which conveys the location of geographic objects through spatial sonification. Users perceive these objects through the virtual listener’s ears walking through the presented area. Evaluating our system

A well-known issue is interpreting the map's geocentric content, which is known to become prone to errors when the map is not aligned to the environment. In this paper we report our investigation of providing a cue about the destination's location from an egocentric perspective in order to improve the interpretation of the map. We used a vibrotactile belt to continuously indicate a destination's direction relative to the user's orientation. In an outdoor field study we compared the performance of map-based navigation with and without the added tactile cue. We found evidence that people take shorter routes, consult the map less often, and were less often disoriented with the tactile cue. Furthermore, females found the tactile cue more useful and used it more often.

A visual support for wayfinding, however, is not reasonable or even possible all the time. A pedestrian must pay attention to traffic on the street, a hiker should concentrate on the narrow trail, and a blind person relies on other modalities to find her way. To overcome these limitations, we developed a non-visual support for wayfinding that guides and keeps a mobile user en route by a tactile display. We designed a belt with vibrators that indicates directions and deviations from the path in an accurate and unobtrusive way. Our first user evaluation showed that on an open field without any landmarks the participants stayed well to given test routes and that wayfinding support is possible with our Tactile Wayfinder.

Previous work has suggested tactile feedback as solution, but it is not yet clear how it should be integrated into handheld navigation systems to improve efficiency and reduce distraction. In this paper we investigate augmenting and replacing a state of the art pedestrian navigation system with tactile navigation instructions. In a field study in a lively city centre 21 participants had to reach given destinations by the means of tactile, visual or multimodal navigation instructions. In the tactile and multimodal conditions, the handheld device created vibration patterns indicating the direction of the next waypoint. Like a sixth sense it constantly gave the user an idea of how the route continues. The results provide evidence that combining both modalities leads to more efficient navigation performance while using tactile feedback only reduces the user's distraction.

However, the chaotic nature of such place makes it difficult to keep the group together. Constantly watching out for the others or frequent use of technology (e.g. phone calls or Google Latitude) may be contradictory to the idea of having a jolly night out. We therefore designed FriendSense, a mobile application that acts as a pervasive anchor to one of the friends. Beyond existing solutions it allows to continuously sense the anchored friend's location through vibro-tactile feedback. In a preliminary field study we investigated how this added sense affects a night out at an Oktoberfest-like festival. We found evidence that FriendSense users were more confident and less stressed with keeping the group together.

However, today's navigation systems try to route users to the destination as fast as possible. In this paper, we present the concept of time-based pedestrian navigation. We use a map on a smartphone that highlights streets depending on whether they will lead to a destination in time. Our map also allows the users to choose between route alternatives during the walk.
