Path Guidance System for the Visually Impaired

摘要

An innovative path guidance system and method has been invented that in a preferred embodiment allows visually impaired people to follow a dynamically changing path that avoids obstacles and arrive at a destination with minimal intervention by a sighted guide. The disclosed invention has the leader set a track electronically, and employs but is not limited to haptic feedback and audible alerts used in combination or individually, to help the visually impaired person control his or her trajectory. The visually impaired follower can be following a leader setting the path in real time or following a path established by a guide at an earlier time and recorded.
