Computerized drafting (Jun, 1973)
Ever dreamed of converting your rough sketches into fully proportioned finished drawings at the stroke of a pen? Well, someone did. IBM now has an experimental system that does just that—courtesy of a computer. Simply place your sketch and a paper “keyboard” anywhere on a special electronic tablet, as shown in the photo. Then you touch the sketch and the keyboard with an electronic pen to enter graphic and alphanumeric data and to activate commands to the computer—”make a circle,” for example. A finished drawing will be produced with correct dimensions coresponding to those fed to the device. The drawing also appears on a screen.
