Abstract: A user interface is implemented using visual indicia and a background for the visual indicia that encodes address information. The background appears visually as a stipple pattern, but is implemented using glyphs which form and address carpet that encodes address information uniquely identifying each area of the user interface. An image capture device is used to select an area of the address carpet that is under or near visual indicia of interest to the user. The image capture device captures the area of interest, and transmits the image area to a computer for processing. The computer first determines the proper orientation of the image, and then decodes the information encoded by the glyphs. The decoding results in an X, Y address identifying the location of the selected area in the address carpet. Based on the address, the computer may perform an operation associated with the area.
