Engineers at the University of Southern California have developed a vest that can guide people with visual impairments. A head-mounted stereo camera feeds 3D data to vision software that identifies obstacles and computes a path around them. The vest contains four micromotors at the shoulders and waist that vibrate like cellphones, alerting users to the location of an obstacle. The next step for the researchers is to shrink the current head-mounted camera system so that it can be mounted on eyeglasses. – Alex Hutchinson
