  • Input device for a portable terminal
    Patent number: 7492354
    Abstract: An input device disposed on the rotatable cover of a portable terminal. The input device is a compound switch that has five binary switching elements. The input device includes an outer, ring-shape element and inner, circular-shape element. When a switching element is actuated, the portable terminal responds, wherein the response is a function of the operating mode of the portable terminal. A graphical representation of the input device appears in the display screen of the portable terminal. The graphical representation includes up to five icons, which correspond to the five binary switching elements. The icons are visually suggestive of the function of the associated switching element. The icons change, as a function of operating mode, to reflect the change in function of the switching elements from mode to mode.
