A pointing device that uses an eraser-sized knob to provide cursor movement. This pointer works like a joystick, moving the cursor in the direction it is pushed.

A Graphical User Interface (GUI, pronounced "gooey") hardware device that replaces the computer mouse. A pointing stick is a pencil eraser-size knob that is usually mounted between the G H and B keys on a keyboard. Pushing the pointing stick in one direction or another moves the mouse cursor. Buttons usually mounted below the keyboard replace the mouse buttons.

The pointing stick (trademarked by IBM as the TrackPoint) is a pointing device (compare especially Touchpad) for laptops invented by research scientist Ted Selker and is present on many brands of laptop, including IBM's line of Think Pad laptops (now made by Lenovo) and on Dell Latitudes under the name of Track Stick. It has also been observed on computer mice and on some desktop keyboards.
