Abstract
A device is provided. The device comprises a conductive element comprising one or more grooves, a capacitive field measurement element coupled to the conductive element, and a controller coupled to the capacitive field measurement element. The grooves comprise material with conductivity lower than the conductivity of the conductive element. The capacitive field measurement element is configured to measure change in the capacitive field in proximity of the grooves caused by physical interaction or proximity between the grooves and an external object, and provide the measurement to the controller. The controller is configured to trigger at least one function assigned to the one or more grooves when a change in the capacitive field in proximity of the one or more grooves is measured. Methods of operation and manufacture are also presented.
