The DataHand came out in 1995, by DataHand Systems, Inc. It's a special input device, where each finger fits into a hole, and the hole has 4 buttons on the sides like a joystick, plus a downward button, and you “type” by moving fingers in each direction. The thumbs also have five buttons: one inside, two outside, up and down.

It was invented by Dale J. Retter in 1992 (according to Wikipedia).

This device, is no good, because fingers are not designed to move in sideways. Better systems for efficient input or chorded, are Stenotype, PianoText, Michela Chorded System.
