A mobile indoor navigation system

摘要

A mobile indoor navigation system comprises: • a mobile communication device incorporating a user interface; a display for navigating a user from a first location to a second location; and a camera; • a number of passive navigation markers disposed at a number of locations; at least one of which in use is viewed by the camera as the marker is in the field of view of the camera; and • a processor which compares signals representative of the viewed passive navigation markers with signals stored on a database and displays navigation information dependent upon the comparison.
