Rand Tablet
1964 The Rand Corporation, United States

The Rand Corporation produced one of the first devices that permitted the
input of freehand drawings into a computer. Also called the Grafacon, the
original Rand Tablet cost $18,000. The attached stylus sensed electrical pulses
relayed through a fine grid of conductors housed beneath the drawing surface,
fixing its position to within one one-hundredth of an inch. Many experimental
systems were developed to recognize handwritten letters or gestures drawn on
the tablet, such as Tom Ellis’ GRaphic Input Language (GRAIL) method of
programming by drawing flowcharts.
