Abstract
A virtual joystick GUI control with self-centering capability which provides a computer system user the ability to scroll at an angle using an n-dimensional graphical control interface. The virtual joystick may be displayed in simple two-dimensional view for control of one dimension of scrolling, such as left/right or up/down. Alternatively, the virtual joystick may be displayed in a simulated three-dimensional (perspective) view which allows scrolling in two dimensions, such as up/down/left/right and combinations thereof. The new virtual joystick can be used to scroll displays, or control other system functions and program parameters, such as volume up/down and tone bass/treble. In general, the virtual joystick can allow control of one or two variables over a range of values.
