Title: Concept Keyboard
Post by: ed_avis on Fri, 28 November 2014, 02:53:53

In the 1980s the Concept Keyboard was a pressure sensitive pad with a resolution of about one inch by one inch.  It was commonly used in British schools plugged into a BBC Micro.  The teacher would make an overlay by drawing dinosaurs or whatever on a sheet of paper, stuck onto the Concept Keyboard, and the computer would be programmed to respond to whichever part of the Concept Keyboard had been pressed.

Yes... 1 dpi... the only resolution where it doesn't matter if you confuse inches and square inches.
