The invention of text messaging has greatly facilitated our lives, but for the blind, they cannot experience the wonders of the SMS world. Recently, a designer named Andrew Mitchell has designed a device called Squibble Portable Braille Interface to help the blind send and receive text messages. As long as one knows Braille, they can read and send messages through the Braille characters on the surface of the device. The official product is still under development, and it is hoped that the visually impaired community can use it as soon as possible~
