Abstract
A roller is provided in an input device such as a joystick to perform functions that compliment its operation. Upon detecting rotational movement of the roller in a first direction by a preset angle, a first signal is generated for activating a first logical button. Upon detecting rotational movement of the roller in a second direction by a preset angle, a second signal is generated for activating a second logical button. Roller rotation by multiples of the preset angle represents a series of button presses. The button press may be assigned a function such as selecting an item from a menu or adjusting attributes of objects or data displayed on a computer screen, such as the selection or firing of weapons or adjustment of shield balance in a video game application.
