指点杆是一种主要应用于笔记本电脑的定点设备。指点杆由科学家Ted Selker发明并应用于多个笔记本电脑品牌，包括ThinkPad、戴尔、惠普，富士通。不同笔记本电脑厂商对其生产的指点杆产品往往有不同的称呼，ThinkPad称其为“TrackPoint”，戴尔则称其为“Track Stick”。指点杆有时也安装在某些鼠标和台式计算机键盘上。ThinkPad 用户群间有时戏称TrackPoint为「小红点」或「中原一点红」。

A pointing stick is an isometric joystick used as a pointing device, as with a touchpad or trackball, typically mounted in a computer keyboard. Movements of the pointing stick are echoed on the screen by movements of the pointer (or cursor) and other visual changes.
