摘要：
A method for force detection of a deformable touch element with a capacitive touch-screen device includes providing drive and sense electrode arrays and a touch-detection circuit connected to the electrodes for detecting capacitance at a touch location. No-touch capacitance, light-touch capacitance, and heavy-touch capacitance are sensed with the touch-detection circuit at the touch location in response to forcible deformation of the deformable touch element proximate to the touch and a force signal reported.
