RADAR IMAGERY IN HEAD-WORN COMPUTING
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.
1 . An apparatus to assist a visually impaired person in navigating an environment, comprising:
a. a head-worn computer;
b. 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
c. 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 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.
2 . The apparatus of claim 1 , wherein the processor is further adapted to interpret movements of the visually impaired person to make a prediction of a direction in which the visually impaired person is walking to assist in the person in navigating the environment.
3 . The apparatus of claim 1 , wherein the feedback cues are visual.
4 . The apparatus of claim 1 , wherein the feedback cues are audio based.
5 . The apparatus of claim 1 , wherein the feedback is haptic based.
6 . The apparatus of claim 1 , further comprising a second radar system having a second angular field that overlaps at least a portion of the angular field.
7 . The apparatus of claim 1 , further comprising a visual light camera, wherein the visual light camera is used to capture an image of an object in the environment in front of the person, wherein the processor is further adapted to identify the object; and wherein the radar system is adapted to identify a distance between the head-worn computer and the object.
