Eric Ju Yoon Kim is the developer of the world's first Braille watch.
The watch lets blind people read real-time smartphone data in Braille.The Dot, a device that straps around the wrist like a watch, uses magnets and a grid of pins to create four braille characters at a time that change at adjustable speeds, allowing users to read text messages and use apps on any device via Bluetooth. The Dot uses a moveable braille interface made of magnets and pins strapped to the wrist like a watch.
