Design of a haptic data visualization system for people with visual impairments

J.P. Fritz, K.E. Barner
1999 IEEE transactions on rehabilitation engineering  
Unfortunately, the amount of information that can be perceived through a haptic interface is considerably less than that which can be perceived through vision, so a haptic environment must be enhanced  ...  This enhancement includes speech output and the addition of object properties such as friction and texture.  ...  When the object was a height map, a more intelligent collision detection algorithm was used which only checked the polygons in a local area around the haptic IP, thus allowing a larger data set to be rendered  ...
