Abstract
A user-controlled input device for use with a computer system is disclosed. The user controlled input device controls at least three-dimensional movement in a three-dimensional virtual space defined by a three axis coordinate system. The device includes a controller body and at least a pressure controlled button joystick coupled to the controller body. Displacement of the button joystick in a first direction translates into directional movement at least about a first axis. The button joystick includes a force sensor wherein an output signal is produced by the button joystick that is proportional to the force placed on the button joystick. The output signal is translated by a computer program into a rate of motion that is proportional to the pressure that is supplied by the user of the input device. In certain embodiments, a second button joystick is coupled to the controller body to control directional movement about a second and a third axis. In such an embodiment, each edge of the force controller controls movement in a different direction. For example, the user can move the cursor using only a single button in both the x and y directions in a three-dimensional virtual space (x,y,z).
