- The combination button-and-scroll-wheel selection device of some iPods.
click-wheel - Computer Definition
The user interface that made the iPod music player popular. Originally using a rotating wheel, the wheel was later made touch sensitive, and its rotation was simulated. People love the way the click wheel operates with one hand. The wheel is swiped in rotation to scroll, and the top, sides and bottom of the wheel are clicked to make a selection. See iPod classic and scroll mouse.
