We've looked at a number of efforts to extend the capabilities of the traditional white cane for the visually impaired, such as using ultrasonic echoes or lasers to give users a better lay of the land. But a group of engineering researchers at the University of Southern California (USC) are looking to do away with the cane altogether and replace it with a "guide vest" that works in conjunction with a helmet-mounted camera and special software to let wearers "see" the world through tactile feedback.
