Patent ID: 8421483

Claim:
A device, comprising: a touch screen configured to sense at least capacitance, force, or a combination of capacitance and force; and wherein the touch screen comprise: a plurality of sensors located at a plurality of locations; a first layer, wherein the first layer is configured as a conductive layer or a screening layer; a second layer coupled to the first layer, wherein the second layer is configured to sense force, and a third layer configured as a conductive layer or a screening layer; a capacitance sensing component coupled to the first layer and the plurality of sensors; a force sensing component coupled to the plurality of sensors, the first layer and the third layer, wherein the force sensing component is configured to determine which particular sensor of the plurality of sensors has been activated and to detect an amount of force applied to the second layer, and wherein the force sensing component generates one of a plurality of force responses, from a set of force responses in response to the force exerted on the particular sensor associated with one of the plurality of locations, wherein the force response is based on at least one of a detected amount of force sensed or a duration of force exerted on the particular sensor, and wherein different areas of the touch screen are configured to have different sensitivities to touch, and wherein the different sensitivities to touch are adjustable.
