greenrainbow writes "Students in Israel at the Ben-Gurion University of the Negev have developed new technology that allows blind people to 'see' objects around them through a simple radar system. The device consists of a computer, two video cameras, and a scanning light source; it audibly alerts the individual of objects that are in close proximity. The system scans surrounding objects and their distance from two points, much like the human eyes. Unlike current sensor canes, this new light scanning device is a hands-free system that can sense objects on the ground, overhead, and in the periphery."
