Historical information

The Tellatouch was developed in the American Foundation research laboratory and resulted from one of the first AFB research projects, a major effort in the mid-1940s to help deaf-blind people. The device helped end social isolation for hundreds of deaf-blind children and adults. The Tellatouch provides a means of communication between a sighted (or blind) person and a deaf-blind person who can read braille. The keyboard has three rows of ten keys each and a standard braille keyboard on the fourth row. At the rear of the machine is a round metal plate with the braille cell in the center. The deaf-blind person rests a finger on the braille cell. Pins rise to form the equivalent of the letter key that is struck. The body of the device covered in beige vinyl, with a hinged lid at the front which lifts up to reveal the keyboard. The lid is secured with a metal latch at the front.
