What is use of lightpen?

A lightpen is a device used in conjunction with a computer monitor to allow users to interact with the screen by pointing directly at displayed objects or text. It emits a light beam that can be detected by the screen, enabling selections or drawing directly on the display. Lightpens were popular in the 1980s and 1990s, but have largely been replaced by touchscreens and stylus pens on modern devices.
