ABSTRACT:
A digitizing tablet is realized by maintaining first and second sheets of insulating material in a spaced apart position by sealing them together and filling the resulting pocket with air or fluid under pressure. Coordinates for the position of a stylus on the face of one of the sheets are obtained with electrical conductors defined on the inner faces of the two sheets. Access for energization and output is obtained at the edges.
