Navigation for the blind using a wireless sensor haptic glove

This paper presents a prototype indoor navigation system for the blind based on wireless sensor network coupled with a haptic feedback glove. The system uses Received Signal Strength Indicator (RSSI) to continuously triangulate the position of the Vision Impaired (VI) person. A number of most relevant destinations can be assigned to pushbuttons on a haptic glove. Upon receiving input from the user via a pushbutton indicating the desired destination a path is routed. To aid in traversing to the destination the individual wears the haptic feedback glove embedded with vibrational motors and an ultrasonic sensor to gauge distance of nearby objects.
