FORCE SENSING INPUT DEVICE
First Claim
1. A device comprising:
- a bezel extending along at least a portion of a perimeter of the device, the bezel having an exterior surface and an interior surface;
a force sensing resistor assembly comprising one or more touch zones 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 bezel;
a haptic generator configured to generate a haptic output; and
a controller coupled to the force sensing resistor assembly and the haptic generator, the controller configured to;
designate one or more of the touch zones as activated, responsive to the incident force;
select a haptic output waveform based at least in part on the designated activation;
using the haptic generator, generate a haptic output based at least in part on the haptic output waveform;
send a signal indicative of the one or more of the activated touch zones to a processor configured to;
determine an action based at least in part on the signal; and
perform the determined action.

Abstract
User input is accepted by a force sensing resistor (“FSR”) assembly, a force sensing capacitor (“FSC”) 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 activation of the assembly. The activation may be processed as input and used to determine and then perform a particular action. The particular action may be based at least in part on a particular portion of the assembly which has been activated, a magnitude of applied force, or both. A haptic output may be provided on activation to provide feedback to a user.
