Techopedia Explains Eraser Pointer

In 1992, the eraser pointer was released by IBM as the TrackPoint, which is built into most ThinkPad (Lenovo) laptop computers. Eraser pointer technology allows users to control mouse movements while using a keyboard. Some eraser pointers have a red, replaceable tip, or nipple.
