A South Korean startup called Dots has created a braille-enabled smartwatch to help the visually impaired receive and read smartphone notifications directly on their wrists.

Resembling a fitness tracker, the Dot is able to display four braille characters at once, thanks to a grid of tiny physical dots that can lower and raise themselves, forming braille letters in the process.

Electronic braille readers have existed for quite some time, but this is the first time their bulky size has been cut down enough to be worn on the wrist.
