The DrawBraille Phone concept was a school project done by Shikun Sun while he was studying industrial design at the UK's Sheffield Hallam University. The haptic phone uses 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.
While the larger size of Braille text versus visual text means the display can only output five rows at a time, the Up-Down buttons to the left enable the user to "scroll down" through infinite "screens." Check it out:
