    Abstract: A keyboard assembly includes a transmitter electrode and one or more receiver electrodes that are used to generate an electric field above one or more keys of the assembly. The first electrode is located on a first level of a keyboard assembly and the second electrode is located on a second level of the keyboard assembly. The first level may correspond to a support plate of the assembly and the second level may correspond to a surface of a printed circuit board to which the second electrode is coupled. Alternatively, the first and second levels may correspond to different sides of a frame of the keyboard assembly. Disturbances in the electric field may be detected to perform a control operation of a host device that includes or is coupled to the keyboard assembly.
