Abstract: An input device for use with computer systems is provided. In one example, an input device includes a touch-sensitive screen and an overlay positioned over the touch-sensitive screen, the overlay having a plurality of tactile features. The touch-sensitive screen is operable to display one or more images, e.g., of multiple keyboard configurations, character sets, or other control functions, to facilitate input to a computer system. The image may be varied to provide a multi-configurable input device. Additionally, the tactile features may include transparent extruded areas, such as ridges, molded key features, indentations, protrusions or the like arranged to provide users with a tactile feel (e.g., for motion and/or location) of varying portions of the underlying displayed image.
