Wearable aid for the visually impaired

For people with impaired vision, students at the University of Washington´s Human Interface Technology Lab have created a prototype that just might solve their problem. We discuss about the wearable vision aid that alerts its users of stationary objects that are near enough for a collision. One of the group´s main design objectives was to create something that could be developed inexpensively. The prototype combines a video camera, a scanner headset, a laptop computer, and software.
