Abstract
Information processing, for example by means of a computer, is served by a tablet in combination with an inputting implement such as stylus or human finger. Such a tablet-implement combination may serve in lieu of or ancillary to other inputting means such as a keyboard. Implement positional information, e.g., as contacting the tablet, depends upon interpolation as between segmenting lines in the tablet. Cost advantage commensurate with resolution/noise desiderata is ascribable to use of analog information (without digitization) in interpolation.
