Aimed at people with severely limited vision, researchers from Oxford Unversity have developed a bionic glasses prototype.
The typical-looking glasses use readily available technology, such as video cameras, position detections, facial recognition, tracking software and depth sensors, to help the visually impaired.
Video cameras are mounted to the corners of the glasses and embedded in the lenses are LED arrays that also serve as a display to relay additional information about the wearer's location. For example, the LEDs can be programmed by color to represent people or objects and by brightness to represent their distance. A pocket-sized computer works in the background to recognize objects or tracks location in real time.
