Nintendo created a hands-free controller for the NES, which was intended for quadriplegic or others with physically-debilitating conditions. The controller would be strapped to the person's chest and the user would use a straw and joystick for the controls; For D-Pad movement, the player would use their chin to move a cupped joystick, and for the A and B buttons, the player would "blow" or "suck" through the straw piece.
The development of the controller was sparked by a letter from a mother of a handicapped girl requesting a controller that her daughter could use to "play the video games she loved." The development project took two years until it was finally released in April 1989, selling more than 100 units since then.
A number of the controllers were also present during the first Nintendo World Championship, for players that required it.
