Abstract: A digitizer system includes a substrate with indicia that uniquely define local areas of the substrate. A multi-mode sensor device, such as a stylus, may sense radiation emitted from the features, and selectively switch to a mode of operation that can sense the indicia and determine therefrom the location of the stylus relative to the substrate.
