Washington: A team of inventors unveiled an electronic wrist band called Sunu that emits a high-frequency sound wave that bounces off objects as far as 14 feet in front of the blind people before registering as a gentle, pulsing vibration on their arms.
The closer the object is - whether it's a wall, rubbish can or person - the more frequent the pulses become, allowing the blind or sight impaired people to create a mental map of the world around them using echolocation, according to (The Washington Post).
Fernando Albertorio, one of the inventors, compares the device to sonar being used in vehicles to sense nearby objects and avoid crashes.
He expressed hop that the invention changes the way visually impaired people get around.
"One of my friends calls the device his 'sixth sense'," Albertorio said, noting that people with vision loss are sometimes afraid of going outside. "It enhances my awareness of my personal space and keeps me safe when I'm out in my neighbourhood."
