A system including a plurality of actuation devices with each actuation device configured to have a metalized and charged to an electrical potential rear part which moves to a designated position representative of a designated manipulation, when at least one actuation device is manipulated, a capacitive sensor array configured to measure a composite electric field produced by the plurality of actuation devices, an acquisition device configured to acquire electric field data indicative of the measured electric field, a converter configured to convert the acquired electric field data into analog values, and a processor configured to evaluate to the analog values to determine which of the at least one actuation devices was manipulated, how the manipulation reflects operation of the control panel, or to provide a response indicative of the manipulation. A method and a computer program product are also disclosed.
