Abstract
A device includes a capacitive sampling unit that measures, at the multiple instances of time during a touch interval, capacitance values of a capacitive touch screen display associated with an area in contact with a finger touching the capacitive touch screen display. The device further includes a touch deformation area unit that determines, at the multiple instances of time, a size of the area upon the capacitive touch screen display in contact with the finger touching the capacitive touch screen display. The device also includes a touch force estimation unit that determines a rate of change in the size of the area in contact with the finger, and estimates a touching force of the finger touching the capacitive touch screen display based on the determined rate of change in the size of the area.
