Breakthrough for the Blind: Scientists Develop Vest That Can 'See'

Video

It works much like a GPS.

Could seeing eye dogs soon be replaced by...vests?  In what could be a major breakthrough for the blind, USC school of engineering has developed a vest that, when worn, can navigate a person safely through their environment. Much like GPS, the system plots out a course pre-selected by each wearer. Stereo-vision cameras attached to the unit perceive depth and guide users along their selected route. The vest also includes vibration motors that alert the wearer if they've deviated off their charted courses.

Developers of the vest soon hope to refine the size and make the product available to the public.
