While touchscreen phones may be the wave of the future, they're not doing any favors for the visually impaired. After all, with nothing tactile on the screen, it's tough for them to control it. But this DrawBraille concept is the opposite.
Designed by Shikun Sun, the DrawBraille concept is designed exclusively for the blind and visually impaired, featuring "a 'display' of mechanically-raised dots on one end and a touch-sensitive sensor on the other end for input; additional raised dots on the phone's edge indicate battery life." Sure, it wouldn't be too easy for someone who can't read Braille to use, but I guess now you know what it's like to have a phone just not be usable for you at all.
