Dual function input device and method
First Claim
1. Apparatus for user input to a digital system, comprising a first sensing system having first sensors for sensing a user interaction of a first kind using a sensing method of a first type, and a second sensing system having second sensors for sensing a user interaction of a second kind using a sensing method of a second type, said first and said second kind of interaction being mutually independent, and at least some of said first and at least some of said second sensors being patterned onto and co-located on a sensing layer of a first single foil in an interleaved manner.

Abstract
Apparatus for user input to a digital system, comprising a first sensing system for sensing a user interaction of a first type, co-located with a second sensing system for sensing a user interaction of a second type. The first system may detect styluses and like objects using EM radiation and the second system may detect touch pressure.
