Abstract

In embodiments, an encoded micro pattern includes segments of encoded bits that can be optically-imaged by a digitizer. The position of each segment in the encoded micro pattern can be determined from the encoded bits in a segment. Each of the segments of the encoded micro pattern also includes a fiducial marker that indicates an orientation of a segment in the encoded pattern. The encoded bits of the encoded micro pattern can be integrated into a display surface of a display device, or integrated in a display screen that is positioned over the display surface of a display device.
