Abstract:
Apparatuses and methods for determining a deflection of a moveable conductive plate that is moved over a capacitive sensing device. The method may include moving the moveable conductive plate over sensor elements of the capacitive sensing device, and determining the deflection of the moveable conductive plate. In determining the deflection, a deflection magnitude and a deflection direction may be determined by calculating a vector of x- and y-directions or a vector of a radius and an angle.
