Navigation System for the Visually Impaired

      Disclosed is a navigation system for the visually impaired.
The system consists of a handheld device which may be in the form of
a cane which contains a radio frequency identification reader or base
station.  Provision is made for audio feedback from the reader to the
person using the system.  Radio frequency identification transponders
or tags are placed at key locations to mark a route to be followed.
The tags may be coded in such a way to indicate their coordinates.

      For example, tags may be placed at intervals along a corridor.
The coded message relayed to the user can indicate the distance
traversed along the corridor.  The tags may be placed in objects,
such as furniture or appliances to aid in their location or
avoidance.
