Students develop device to guide blind around obstacles
Washington: Engineering students Elad Kuperberg and Einav Tasa of Ben-Gurion University of the Negev in Israel have developed an optical radar system that can help blind people move around obstacles. The radar system incorporates a computer, two video cameras and a scanning light source to warn the blind of obstacles with audible alerts. "This optical radar device is not only user friendly, but unlike the other solutions it allows the blind to have the use of both of their hands," said Professor Shlomi Arnon, who guided the students in their project. The system detects obstacles - even those overhead - by scanning the depth of its surroundings, taken from two different angles - similar to that of the human eye. The device was shown for the first time last week as part of the annual conference of projects in the Department of Electrical and Computer Engineering.
