ABSTRACT:
The present invention provides a system, method and apparatus to assist a user navigate from a current location to a second location within an environment by determining a distance traveled by the user or from the user to one or more objects. The current location is then identified using the distance and an environment data. Thereafter, a route to the second location is determined based on the current location and the environment data, and a directional cue is provided to the user based on the route. Note that the present invention can be implemented as a computer program embodied on a computer readable medium wherein the steps are performed by one or more code segments.
