Pressure sensitive key normalization
First Claim
1. An input device comprising a plurality of pressure sensitive keys configured to initiate corresponding inputs of a computing device, each of the plurality of pressure sensitive keys formed from flexible contact layer spaced apart from a sensor substrate by a spacer layer, a first said pressure sensitive key configured to have a greater sensitivity to pressure than a second said pressure sensitive key throughconfiguration by varying amounts of force sensitive ink.

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.
