=== Trackball ===
{{Main article|Trackball}}
A [[trackball]] is a smooth sphere that is manipulated with the palm of one's hand. The user can roll the ball in any direction to control the cursor. It has the advantage that it can be faster than a mouse depending on the speed of rotation of the physical ball. Another advantage is that it requires less space than a [[Computer mouse|mouse]], which the trackball was a precursor of. Notable uses of a Trackball as a gaming controller would be games such as ''[[Centipede (video game)|Centipede]]'', ''[[Marble Madness]]'', ''[[Golden Tee Golf]]'' and ''[[SegaSonic the Hedgehog]]''.
