Professor Markus Meister and his laboratory combine augmented reality technology with computer vision algorithms to create goggles that can help blind people navigate unfamiliar spaces. The Meister lab had great success with initial testing and hopes the technology can one day be offered by places like banks, grocery stores, museums, and more.
