1. An apparatus comprising:
- a surface, the surface has a conductive layer within a thickness of the surface;
a trench, the trench is formed in the conductive layer to define a touch area, the touch area is isolated from the rest of the conductive layer; and
a conductive pickup, the 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.

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.

8. A method comprising:
-
partitioning a conductive layer of a surface into a touch area and a first remainder area with a trench to isolate the touch area from the first remainder area; mounting a pickup over the touch area; and electrically connecting the pickup to an input of a capacitive touch controller, wherein when a user touches the touch area, the capacitive touch controller generates a response. - View Dependent Claims (12, 13, 14)
