A 6th sense for blind people

post-image
A wristband called Sunu emits a high-frequency sound wave that bounces off objects as far as 14 feet in front before registering as a gentle, pulsing vibration. The closer the object is ? whether it?s a wall, trash can or person ? the more frequent the pulses become, allowing blind people to create a mental map of the world around them using echolocation. It?s like the sonar device being used in vehicles to sense nearby objects and avoid crashes. https://www.washingtonpost.com/news/innovations/wp/2017/10/27/for-decades-the-blind-have-used-canes-to-get-around-now-an-special-wrist-band-helps-them-locate-hazards/?
