have developed a high-tech device for helping visually-impaired people get around. The system consists of a head-mounted camera connected to a computer that uses a special software, called Simultaneous Localization and Mapping (SLAM), to convert images of the environment into three-dimensional spatial maps to determine a safe route around obstacles.

The route information is sent to a vest containing four motors on each side of a person’s shoulder and waist that vibrate if an obstacle is in his or her path.
Recall that we also wrote a couple months ago about a similar setup from the University of Konstanz in Germany that uses a hacked Microsoft Kinect sensor to assist in navigation.
