Pressure sensitive key normalization
First Claim
1. An input device comprising a plurality of pressure sensitive keys, a first individual pressure sensitive key of the pressure sensitive keys configured to initiate a corresponding input of a computing device by making contact between two or more conductors of a plurality of conductors disposed in a single layer on a sensor substrate via a force sensitive ink disposed in a layer proximate to the single layer containing the plurality of conductors, the pressure sensitive keys formed from a flexible contact layer spaced apart from the sensor substrate by a spacer layer, the first individual pressure sensitive key configured to have a greater sensitivity to pressure than a second individual pressure sensitive key of the pressure sensitive keys through a configuration of the plurality of conductors.

Abstract
Pressure sensitive key techniques are described. In one or more implementations, a device includes at least one pressure sensitive key having a flexible contact layer spaced apart from a sensor substrate by a spacer layer, the flexible contact layer configured to flex responsive to pressure to contact the sensor substrate to initiate an input, for a computing device, associated with the pressure sensitive key. At least one of the flexible contact layer or the sensor substrate are configured to at least partially normalize an output resulting from pressure applied at a first location of the flexible contact layer with an output resulting from pressure applied at a second location of the flexible contact layer that has lesser flexibility than the first location.

10. A method of manufacturing an input device, the input device comprising a plurality of pressure sensitive keys, a first individual pressure sensitive key of the pressure sensitive keys configured to initiate a corresponding input of a computing device by making contact between two or more conductors of a plurality of conductors disposed in a single layer on a sensor substrate of the input device via a force sensitive ink disposed in a layer proximate to the single layer containing the plurality of conductors, the method comprising:
-
configuring the first individual pressure sensitive key to have a greater sensitivity to pressure than a second individual pressure sensitive key of the pressure sensitive keys through a configuration of the plurality of conductors disposed on the sensor substrate; and forming the pressure sensitive keys by combining a flexible contact layer with the sensor substrate, the flexible contact layer spaced apart from the sensor substrate by a spacer layer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
