This abstract first appeared for US patent application 20250085807 titled 'TOUCHPAD FORCE CALCULATION USING NO-TOUCH CAPACITANCE
Original Abstract Submitted
methods and computing devices for estimating a force f exerted on a touchpad are disclosed. in one example, a method comprises determining that the touchpad is not being touched. at least on condition of determining that the touchpad is not being touched, a no-touch capacitance value of the pcb is calculated. after calculating the no-touch capacitance value, the method includes determining that the touchpad is being touched. at least on condition that the touchpad is being touched, the no-touch capacitance value and a touch-based capacitance value are used to estimate the force f exerted on the touchpad.
