Aspects of the present disclosure relate aids for the visually impaired. An apparatus to assist a visually impaired person in navigating an environment includes a head-worn computer, a radar system mounted on the head-worn computer and positioned to measure distances to objects in the environment within an angular field in front of the visually impaired person wearing the head-worn computer, and a processor adapted to process the measured distances from the radar system and to identify objects in the environment that are within the angular field in front of the visually impaired person. The processor is further adapted to generate feedback cues to the visually impaired person in correspondence to the measured distances within the angular field in front of the visually impaired person as the visually impaired person moves his head from side to side while navigating the environment. |
