The trackball was invented by Tom Cranston and Fred Longstaff as part of the Royal Canadian Navy's DATAR system in 1952[1], eleven years before the mouse was invented. This first trackball used a Canadian five-pin bowling ball. The world's first trackball invented by Tom Cranston, Fred Longstaff and Kenyon Taylor working on the Royal Canadian Navy's DATAR project in 1952. It used a standard Canadian five-pin bowling ball. When mice still used a mechanical design (with slotted 'chopper' wheels interrupting a beam of light to measure rotation), trackballs had the advantage of being in contact with the user's hand, which is generally cleaner than the desk or mousepad and doesn't drag lint into the chopper wheels. The late 1990s replacement of mouseballs by direct optical tracking put trackballs at a disadvantage and forced them to retreat into niches where their distinctive merits remained more important. Most trackballs now have direct optical tracking which follows dots on the ball. As with modern mice, most trackballs now have an auxiliary device primarily intended for scrolling. Some have a scroll wheel like most mice, but the most common type is a “scroll ring” which is spun around the ball. Kensington's SlimBlade Trackball similarly tracks the ball itself in three dimensions for scrolling.

- While Trackballs are generally activated by attacks, there are areas (for example in The Great Maze) that feature "chains" of Trackballs. When hit, the first Trackball will smash into the other Trackballs, which causes them to move at their greatest possible speed (regardless of how fast the original was moving). There are a few Giant Trackballs in The Wilds II. Their paths remain invisible until they are struck and obviously they deal more damage. On higher difficulties, Trackballs are harder to move, and run out of momentum faster, meaning they must be hit stronger and more frequently to destroy enemies.

Three major companies Logitech, A4Tech, and Kensington currently produce trackballs, although A4Tech has not released a new model in several years. Microsoft was a major producer, but has since discontinued all of its products. The Microsoft Trackball Explorer continues to be extremely popular (it has no analogous design in production by another company), with used models selling for ~$200 on ebay.
