A computing device (1) includes a controller (4), a radio unit with an antenna (5), detection element (3) and interface element (2). The interface element output, in response to a user actuation, towards detection element (3) a change in a defined physical characteristic. The detection element (3) include dielectric material and are located within the computing device spatially separated from the interface element (2). The detection element (3) is configured to detect the change output by the interface element and output to the controller (4) a signal that corresponds to the change in the defined physical characteristic. The distance from any part of the antenna to a straight line connecting any part of the interface element with any part of the detection element is at some point less than 6 mm.
