Abstract

Various embodiments provide a capacitive touch input element that is formed of a recess in a substrate. The size and shape of the recess are chosen such that a finger of a user will not contact the bottom or minima point of the recess, thereby, requiring pressure to be applied by the finger in order to make contact. Beneath the substrate is a capacitive sensing electrode designed to concentrate an electric field toward the minima point of the recess such that the finger must make contact with the minima point to effect a change in capacitance causing the capacitive touch element to provide input to an appropriate application.
