Invented around 1945 as a part of the Whirlwind Project at MIT, a light pen contains a light-sensitive detector. When you point the Light Pen to an object, its light-sensitive tip detects the object and then sends the signals to the CPU. Its use today is limited since it is not compatible with LCD screens.
