Abstract
A personal navigation system, particularly for use by the blind, combines signals from a satellite-based global positioning system, an electronic map (20), a route-planning algorithm (17) and a tactile display (29) associated with a speech synthesizer (26) (or a control handset associated with a speech synthesizer) to present the road features both around the position of the person using the system and the desired destination. A route to a desired destination can be indicated using a route-planning algorithm (17) and verbal navigation information regarding the current position of the user, the route and the destination can be output via a speech synthesizer (26).
