Abstract
An improved user input device is disclosed whereby the device is equipped with a trackball in addition to other control devices, such as an analog stick controller (e.g., thumbstick or joystick). The trackball is mounted in such a way that it projects both upwardly and downwardly from the device body in the vertical plane. The user is able to touch and use the trackball from both the upper and lower directions. In a preferred embodiment, the trackball is clickable, affording greater control and ease of use.
