Determination of input from force sensing input device under an unbroken exterior portion of a device
First Claim
1. A device comprising:
- an unbroken portion of an exterior of the device, the unbroken portion comprising a structure having an exterior surface and an interior surface;
a force sensing resistor assembly comprising a first touch zone and a second touch zone, each zone configured to be responsive to an incident force, wherein the force sensing resistor assembly is proximate to at least a portion of the interior surface of the structure;
a controller coupled to the force sensing resistor assembly, the controller configured to;
determine a first magnitude of a first applied force at the first touch zone and a second magnitude of a second applied force at the second touch zone of the force sensing resistor assembly;
sum the first magnitude and the second magnitude to generate a summed magnitude of applied force;
determine that the summed magnitude of applied force exceeds a first threshold;
based on the summed magnitude of applied force exceeding the first threshold, dynamically adjust the first threshold; and
determine that one or more of a plurality of touch zones, which correspond with the first magnitude or the second magnitude, are activated.

Abstract
User input is accepted by a force sensing resistor (“FSR”) assembly, a force sensing capacitor (“FSC”) assembly, or both. The FSR or FSC assemblies may be located within an input device, such as behind a device exterior, display, and so forth. A force applied to the device exterior proximate to the assembly may result in a signal indicative of the force to the assembly. The signal may be processed to determine a particular touch zone was activated. A particular action associated with the touch zone may be performed. The particular action may be based at least in part on which touch zone which was activated, a magnitude of the force, or both. For example, the particular action may include a haptic output to provide feedback to a user.
