An endless belt containing solid segments with six pins each was designed. The perforated tape would be driven in synchronism with the belt above and the protruding pins, moving toward the left, would display a line of moving Braille characters. Sounds simple ... but the tape is not dimensionally stable, it is not flat enough, and it breaks easily. The moving belt had to be made compliant, it had to have sprocket pins to drive the tape, and great machining precision had to be maintained. Then the system was motorized and packaged as shown in the photograph above. It runs at over 130 words per minute and has been tested several times in public, although it as never completely evaluated in a formal manner. Project lacked the necessary founds to do it.
