Light pen is a mechanical or optical device?
i don't know answer for this
A light pen is called so because it is a handheld input device that can detect light on a computer screen. It uses a photocell to detect the presence of light emitted by the screen, allowing it to function as a pointing device.
An optical pen is a device used to scan and digitize text or images from a physical surface, such as paper. It converts the analog information into digital format, allowing users to edit, store, or share the content electronically. This makes it easier to work with the scanned content without the need for manual transcription.
A light pen is a pointing device that allows users to interact with a computer screen by detecting light generated by the screen. It was commonly used in the past for drawing, selecting items, and entering data directly on the screen.
A ballpoint pen is a writing instrument that uses a small rotating ball at the tip to disperse ink onto paper as it is moved across. It is a type of mechanical device that allows for precise and controlled writing.
The first light pen was invented in 1955 by computer scientist Ben Gurley at the Royal Canadian Navy Tactical School. It was originally used as a pointing device for computers.
