This is a great advancement, I can really see this benefiting so many. The added bonus with the social distancing is that we don’t have t come in contact with a surface that has been manhandled by so many others. I hope this technology can evolve and be implemented in many public kiosks and ATM machines. It may be a bit of shock, because the ultrasonic speakers “project” the braille dots onto the palm when it is held about 20 centimetres away from the display. I can’t wait to try this tech!
