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.
