The invention provides a non-invasive tongue based with a tongue sensor device arranged for position in the oral cavity of the user. A sensor panel to be placed on an upper part of the oral cavity of the user, and having a 2D array of activation zones and related electric coils. A guide structure, e.g. a metal or polymer frame, carries a ferrous or metallic activation unit movably in a plane upon manipulation by the user's tongue. This allows the user to position the activation unit in relation the activation zones. The guide structure allows the activation unit to move also perpendicular to the plane, to allow the user's tongue to manipulate the activation unit near one activation zone for activation of the activation zone. An electronic circuit inductively senses activation of any one or more of the plurality of activation zones and related electric coils and generates an output accordingly, e.g. a wireless RF output. E.g. a frame structure of metal wires or bars can be used to implement the guide structure, thus allowing the activation unit, e.g. a metal sphere or cylinder, to form an integrated part of the rather than being mounted in an invasive way on the user's tongue.
