A light pen is a light-sensitive computer input pointing device shaped like a wand. It is connected to a visual display unit or CRT monitor and allows the user to modify data and text or make menu selections on the screen. Light pens became popular during the 1980s.
The earliest pens were made from hollow reeds and, later, hollow wing feathers of geese and swans, called quills, infused with ink. Steel pen nibs came into use in the early 1800s, and then fountain pens, which did not require a constant resupply of ink like previous incarnations, gained popularity.
