1. A system that provides feedback to a user to guide the user to an object, comprising:
a frame configured to be worn on a head of the user;
at least one camera mounted on the frame;
a processor adapted to identify at least one object and a hand of the user in a field of view of the at least one camera, to track relative positions of the hand relative to an identified object, and to generate at least one control signal for guiding the hand of the user to the identified object;
a communication device associated with the processor that communicates the at least one control signal; and
a user feedback device configured to be worn on or adjacent the hand of the user and adapted to receive the at least one control signal from the communication device and to convert the at least one control signal into at least one of sounds or haptic feedback that guides the hand to touch the identified object.
