Abstract :
A portable device that enables a visually impaired traveler to determine distance and direction of travel to a desired destination point quickly and accurately is being developed. Coordinates of the traveler´s current position will be determined through the use of NAVSTAR Global Positioning Systems (GPS). A microcontroller will use the coordinates obtained from a GPS receiver as a point of reference from which to calculate the distance and direction to a desired destination whose coordinates were previously stored in memory. The microcontroller will perform all the necessary mathematical operations to output sufficient information so that the traveler can reach the final destination
