Virtual control for touch-sensitive devices
Abstract:
A virtual control is displayed on a touch-responsive display screen. The virtual control visually is displayed as multiple control segments, and layered over an active graphical user interface (GUI). When a contact and subsequent movement is detected on the surface of the display screen at a selected control segment, the selected control segment visually detaches and moves in the direction of the movement. Simultaneously, the GUI is instructed to cycle through a plurality of available program options based on a current position of the selected control segment on the display screen. When the contact is released, the GUI is set to a selected option corresponding to the current position of the selected control segment.
