For people with impaired vision, employing seeing-eye dogs and using canes can be immensely helpful in avoiding obstacles and negotiating changes at ground level such as steps and curbs. However, such tools usually aren?t much help with higher obstacles that might hit them in the face or chest, such as tree branches, street signs, and awnings. Students at the University of Washington?s Human Interface Technology Lab have created a prototype of a wearable aid that might solve this problem.<p>Also in this department: "Glacial Sensors Track Global Warming" and "Virtual Fences: Herding Cattle from Home?"</p>
