Prototype glasses help the visually impaired avoid obstacles

The crafty engineers at Google aren't the only ones working on augmented reality glasses. Researchers at the Instituto de Oftalmología Aplicada have created a prototype system, based around a head-mounted display and a pair of small cameras. Instead of overlaying info about landmarks or capturing video of your trampoline-based escapades, this prototype is simply meant to help the visually impaired detect and avoid obstacles. A small computer performs real-time analysis of the environment highlighting objects and color coding them to indicate distance.
