1. An input apparatus for at least one of operating or controlling a technical device, the apparatus comprising:
a plurality of sensor elements configured to be arranged spatially distributed in an oral cavity of a user in order to detect at least one of a respective current tongue position or respective tongue movement of the user,
an antenna,
an interface circuit coupled to the sensor elements via the antenna,
wherein the interface circuit is configured to generate an interrogation signal and transmit the interrogation signal into the oral cavity via the antenna,
wherein the sensor elements each include a transponder configured to receive the interrogation signal and to transmit an individually encoded response signal in response to the interrogation signal, with each transponder being configured to generate the individually encoded response signal having an individual code identifying the respective transponder,
wherein the transponder is a Surface Acoustic Wave (SAW) tag with an individual coding in the form of a spatial distribution of reflection points, so that the individually coded response signal contains in each case a plurality of reflections whose temporal spacing relative to the interrogation signal and relative to each other represents the individual coding, and
wherein the interface circuit is further configured to receive at least one individually encoded response signal from at least one sensor element and to generate a control signal for the at least one of operating or controlling the technical device as a function of the individually encoded response signal.
