The RAND Tablet is a graphical computer input device developed by The RAND Corporation. The RAND Tablet is claimed to be the first digital graphic device that is low cost. The creation of the tablet was performed by the Advanced Research Projects Agency. The RAND Tablet was one of the first devices to utilize a stylus as a highly practical instrument.'''

The tablet is connected to an input of a computer and/or an oscilloscope display. The display would register the input and display it on the computer screen.

Description
The RAND Tablet is a large 10"x10" printed-circuit screen with printed-circuit capacitive coupled encoders and 40 external connections. The surface has 100 lines per inch resolution so it is able to digitize in over 1 million locations. This is why the handwriting functionality appeared to be so natural. The tablet connects to the input channel of a general-purpose computer and to an oscilloscope display which controls the multiplexes of the pen position information.
