  • Optical position determination on plain paper
    Publication number: 20020158848
    Abstract: The present invention is a form of a digitizer and absolute position determination device for indicating the instantaneous position and movement of a stylus on a surface. It proposes the use of at least three points of position-related information for indicating X-Y coordinates and a surface such as paper comprising two points of the three points of position-related information. The stylus or pen 2 in FIG. 1 comprising a writing element 6 and one of the three points of position-related information has a light source 16 illuminating the surface. A detector 3 comprising a charge-coupled device (CCD) located on the stylus detects the position-related information. The position-related information from the CCD is sent to a computer for processing and finally the desired information output to the user. Different frequency(s) of light can be used depending on the application. During the process of writing, position-related information is detected and sent to the computer for analysis, and finally output to the user.
