11. LIGHT PEN

12. Light Pen
A light pen is a computer input device in
the form of a light-sensitive wand used
in conjunction with a computer's
cathode-ray tube (CRT) display. It allows
the user to point to displayed objects or
draw on the screen in a similar way to a
touchscreen but with greater positional
accuracy.

13. History of Light Pen
The first light pen was invented by Ben Gurley in 1959. The basic idea for the
computer mouse came to Douglas Engelbart in 1961, while he was attending a
computer graphics conference. He was unsatisfied with the other pointing
devices available at this time.
