Navigation Aid for the Visually Impaired
If this hack from University of Konstanz students Michael Zöllner and Stephan Huber reaches the open market, life could get a lot simpler for the visually impaired. As part of a graduate project, this dynamic duo has developed a helmet-mounted Kinect setup that acts as eyes for visually challenged users. The Kinect is combined with a prototype, vibrotactile waist belt to digitally analyze the wearer's indoor surroundings and give audio navigation commands to guide him or her through the area [source: Zöllner and Huber]. It's very similar to the way a GPS system in your car directs you to turn left or right at the appropriate point in your journey (hopefully).
At the moment, this system also requires a slightly clunky backpack, which carries a laptop to process all of the information from the belt and the Kinect. With just a little streamlining, though, this could easily be the replacement for the white cane normally used by visually impaired people to navigate their surroundings.
