“System with a Touch Screen and a Digitizing Tablet”

“…both integrated in an input device”

Patent #5402151 (Google Patents)

  1. “…multipurpose data input device formed by a touch screen and a digitizing tablet integrated with one another, which are activatable independently of each other by proper stimuli.”

My thoughts:

  • My initial thought was that this patent illustrated my thesis idea of “stacking inputs”, but further understanding of the illustrations pointed out that the patent is the idea of having one surface that allows finger touch and a stylus as input. The patent is for “stacking” hardware, but NOT stacking interactions.
