Referred to as an enabler of a sixth sense, the Sunu bracelet employs echolocation technology to help blind and visually impaired individuals understand what’s around them. The device sends forth a high-frequency sound-wave up to 14 feet away. When they strike something and bounce back, the band pulsates. The closer the object, the more frequent the vibration. And all of this, including range and sensitivity, are customizable within the Sunu app. These functions help users build a mental map of the world around them much the same way vehicles use sonar. Many more developments are planned—or are being considered—with a view in mind to help the more than seven million people living with a visual disability. Read the Washington Post’s account of cofounder and user, Fernando Albertorio, to learn more.
