They've been around for 40 years and they used to make digitizers.

From a 1982 NIH article on Nucleic Acids Research: Quote: The magnified image is then traced, along the top side of the viewing screen, using a digitizer. The digitizer used in this system is a NUMONICS GRAPHICS CALCULATOR which was chosen because it can be used with a back projected image, is of sufficiently high accuracy and of reasonable cost. This digitizer can resolve 0.025 cm over a working range of 59 cm x 59 cm. As the tracing head is moved along the image, a stream of X-Y coordinates is accepted by the computer at a rate of more than 100 coordinate pairs/sec via a BCD interface.
