Watch the Hand

The PlayStation controller uses a lighted globe at the end of a wand (two are shown below) to precisely place a character in three-dimensional space. A camera tracks the ball to determine the position of the player’s hand; crucially, it uses the apparent size of the ball to gauge depth. This allows precise placement of a character’s hand, which is helpful when shooting things.
