Researchers at the Technical University of Munich (TUM) have developed a surprising system to aid visually impaired people, consisting of a 3D camera, worn like glasses, and a haptic feedback sleeve that uses vibrations to signal the presence of obstacles nearby.

In a paper shared online on arXiv, in view of forthcoming publication in a scientific journal, Manuel Zahn and Armaghan Ahmad Khan explain how the system works.
