Abstract
A force applied to a force-sensing touch screen device may be determined as follows. A deformation sensing layer of the device may measure an actual deformation of a touch screen of the device. A force sensor of the device may measure a sensed force applied by the touch screen to the force sensor of the device. A processor circuit of the device may determine an expected deformation expected to be imparted to the touch screen by the sensed force. The processor circuit may determine a virtual deformation based on the expected deformation due to the sensed force and the measured actual deformation. The virtual deformation may indicate the force applied to the force-sensing touch screen.
