Claim 17:
18. A method according to claim 17 wherein:
detecting the increase in the first capacitance relative to the capacitance between the first sensor electrode and the base electrode in the absence of the shear force corresponds to an increase in an overlap area of an inner surface of the first sensor electrode that overlaps an inner surface of the base electrode in the direction oriented along the first inner surface normal vector relative to the overlap area of the inner surface of the first sensor electrode that overlaps the inner surface of the base electrode in the absence of the shear force;
detecting the decrease in the second capacitance relative to the capacitance between the second sensor electrode and the base electrode in the absence of the shear force corresponds to a decrease in an overlap area of an inner surface of the second sensor electrode that overlaps the inner surface of the base electrode in the direction oriented along the first inner surface normal vector relative to the overlap area of the inner surface of the second sensor electrode that overlaps the inner surface of the base electrode in the absence of the shear force.
