TrackPoint         
<hardware> (Or "pointing stick", "nipple") A small knob found in the middle of some keyboards that works like a very short isometric joystick. Pressing it toward or away from you or from side to side moves the pointer on the screen. Ted Selker brought the concept of an in-keyboard pointing device to IBM in September 1987. TrackPoint was introduced in 1992 on the IBM ThinkPad and later on some desktops. It takes up virtually no extra room on the box or the work area and also requires minimal movement of the hands from the keyboard. Many imitations of highly variable quality appeared. Pointing sticks have also been used in many other notebook brands, including TI, HP, Compac, Dell, Toshiba (e.g. Portege 4000's "AccuPoint II"), and AST (e.g. Ascentia 910N). "TrackPoint" and "Trackpoint" are IBM trademarks. http://research.ibm.com/mathsci/cmc/trackpoint.htm. [INTERACT'90, North Holland Pub Co, pp. 700-706]. (2003-10-15)

<hardware> Any kind of joystick where the input depends on the force exerted rather than the position of the control, e.g. TrackPoint. (2003-06-26)

A pointing stick (or trackpoint, also referred to generically as a nub or nipple) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the pointer or cursor on the monitor.

Pointing stick

A pointing stick (or trackpoint, also referred to generically as a nub or nipple) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the pointer or cursor on the monitor. Unlike other pointing devices, it reacts to sustained force or strain rather than to gross movement, so it is called an "isometric" pointing device. IBM introduced it commercially in 1992 on its laptops under the name "TrackPoint", patented in 1997 (patent expired in 2017).

The pointing stick senses applied force by using two pairs of resistive strain gauges. A pointing stick can be used by pushing with the fingers in the general direction the user wants the cursor to move. The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. The relation between pressure and cursor or pointer speed can be adjusted, just as mouse speed is adjusted.

On a QWERTY keyboard, the stick is typically embedded between the G, H and B keys, and the mouse buttons are placed just below the space bar. The mouse buttons can be operated right-handed or left-handed due to their placement below the keyboard along the centerline. This pointing device has also appeared next to screens on compact-sized laptops such as the Toshiba Libretto and Sony VAIO UX.
