Abstract:
A device may include a first layer, a second layer, a third layer, a capacitive sensing component coupled to the first layer, and a force sensing component coupled to the first layer and the third layer and configured to detect the amount of force applied to the second layer. A method may include monitoring capacitance and voltage at one or more input sensors configured to detect changes in capacitance and to detect changes in applied force, detecting a change in capacitance, activating a capacitance response in response to detecting a change in capacitance, detecting a change in voltage, and activating a force response in response to detecting a change in voltage.
