NAVIGATION SYSTEM |
摘要 |
A navigation system, used for example to navigate visually handicapped people, uses a satellite system such as the GPS system to locate the user via a user held receiver (14). A two-way communication system such as a digital telephone (18) communicates with a central service centre (10) at which the user's exact location and navigational information can be determined. There is preferably provided a human-to-human information interface (30). The use of a two-way communication system (18) enables some of the components (20-30) to be kept at a remote and stationary base station (10).
