Pressure sensitive key normalization
First Claim
1. A device comprising at least one pressure sensitive key comprising a flexible contact layer spaced apart from a sensor substrate by a spacer layer, the flexible contact layer configured to flex in response to an application of 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 by using conductors of the sensor substrate at a second location of the sensor substrate that have a larger surface area along a plane of the sensor substrate larger than conductors at a first location of the sensor substrate that corresponds to the first location of the flexible contact layer.

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.
