Abstract
A system and method provide feedback to a user, such as a visually impaired user, to guide the user to an object in the field of view of a camera mounted on a frame worn on the head of the user. A processor identifies at least one object and a body part of the user in the field of view of the camera and tracks relative positions of the body part relative to the identified object. The processor also generates and communicates at least one control signal for guiding the body part of the user to the identified object to a user feedback device worn on or adjacent the body part of the user. The feedback device receives the control signal(s) and converts the control signal(s) into at least one of sounds or haptic feedback that guides the body part to the identified object.
