Low-Resolution Supplementary Tactile Cues for Navigational Assistance


The TactGuide is a mobile navigation device ‘displaying’ personalized direction cues by means of a tactile and ‘tactful’ representation. The TactGuide is operated by tactile inspection which is subtle enough to allow the users to engage/disengage in device interaction while preserving their visual, auditory and kinesthetic senses for inspection of the environment. The TactGuide design thereby accommodates the users’ need to economize their attentional resources between device and environment while navigating through physical space. Preliminary experiments indicates that users readily map the tactile cues to spatial directions and that TactGuide can be operated as a supplement to, and without compromising, the use of our existing wayfinding abilities. substituting the use of our natural abilities and earned skills for wayfinding.
