Abstract
This invention relates to a system for orienting and guiding visually impaired pedestrians. The system combines a Global Positioning System (GPS) receiver to a dead reckoning unit that compensates for GPS imprecision and loss of signal. The system is highly portable: it is based on a handheld portable computing platform that communicates wirelessly with a self-powered strap containing the GPS receiver and the dead reckoning unit. The system also uses wireless protocols to receive additional orientation information from a remote location server or operator accessible through the internet.
