Abstract: A device for transferring keyboard commands from a user to an electronic apparatus or machine. An arm intended to be carried by the user as a headset, is provided with signal sensors responding to the presence or pressure of the user's tongue by emitting an electric signal or impulse. A signal unit registers and converts signals from the sensors into corresponding keyboard commands which are then input to the electronic device or machine. The device thus basically works as a keyboard where the signal sensors constitute keys that can be operated solely by the tongue, i.e. without involving the hands.
