Abstract
An apparatus includes a surface; the surface has a conductive layer within a thickness of the surface. A trench is formed in the conductive layer to define a touch area, the touch area is isolated from the rest of the conductive layer. A conductive pickup is mounted on a back side of the surface over the touch area and the conductive pickup is electrically connected to a capacitive touch controller, such that when a user touches the touch area on a front side of the conductive the touch controller responds to the user's touch.
