Abstract

Tactile or interactive maps are largely used as an orientation aid for visually impaired people. Yet, little is known about haptic exploration strategies and their influence on the resultant cognitive mapping. We have designed a prototype with the potential to automatically analyze different users' exploration strategies. This prototype integrates data from the MS Kinect camera and a multi-touch table. It registers location of hands and digits on a tactile map. Results of preliminary studies show that this approach is promising.
