A light pen is a computer input device that allows users to interact with a computer screen by pointing or drawing directly on the monitor. It picks up light emitted by the screen to determine its position, enabling users to select items or input data by tapping on the screen with the pen. Light pens were commonly used in early computer systems before the widespread adoption of touchscreens and other input devices.
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 Lightpens were popular in the 1980s and 1990s, but have largely been replaced by touchscreens and stylus pens on modern devices.
A light pen operates by detecting the light emitted from a computer screen when activated by a user pressing the pen against the screen. The screen emits electron beams that are picked up by the light pen, allowing the computer to determine the location on the screen that the pen is pointing at.
