DotLumen's haptic headset could help blind people navigate
Briefly

"The headset looks like a chunky piece of VR gear, with a front unit sitting on your forehead... In the front, there are six computer vision cameras - three near field and three pointed further away... This is about collision avoidance, preventing you from bumping into pedestrians or street obstacles."
"When the vibrations are in the center of your forehead, it's safe for you to move forward, but when the vibrations move either side, you should turn to refocus."
