A graphical user interface for a computer includes a dial control. The control can be implemented, for example, as a touch-based, pointer-based, pen-based and/or keyboard-based mechanism. The dial control is intended for manipulating a large range of values, such as a menu of items from which a user makes a selection, or a range of continuous or discrete values. A dial control can replace other control types such as a slider, drop down menu or text field. The graphical elements of the dial control include one or more displayed rings and a handle for each ring. Inside the ring, or in another area adjacent the ring, a value can be displayed. The ring can be manipulated by the user to change the value selected by the dial control. In the case of multiple rings, each ring can be manipulated independently.
