ABSTRACT
Most of existing navigation systems for the blind require a precise GPS maps. This makes them unusable in regions where there are no GPS maps, or they are not sufficiently accurate. Algorithm for GPS navigation for the visually impaired along a GPS track, which describes the path as a sequence of waypoints, is proposed. The main advantages of the algorithm are: natural voice navigation, adaptive to the velocity and accuracy of the GPS data, start of the navigation from any waypoint; correction of the direction of movement if it is necessary, return the user to the route if deviation is detected, work with and without electronic compass, detection of the movement of the user in the opposite direction.
