Abstract: A system for structure-borne sound communication within the system. The system includes a first electronic device and a second electronic device, wherein the first electronic device includes at least a first processing unit and a first structure-borne sound actuator, wherein the first processing unit is configured to emit a first structure-borne sound signal by means of the first structure-borne sound actuator, and wherein the second electronic device includes at least a second processing unit and a second structure-borne sound sensor, wherein the second processing unit is configured to detect a structure-borne sound signal by means of the second structure-borne sound sensor and, depending on the detected structure-borne sound signal, to determine whether a mechanical connection is present between the first electronic device and the second electronic device.

Abstract: A method for controlling data glasses. The method includes a step of reading a sensor signal of a sensor unit arranged on the data glasses, wherein the sensor signal represents a change of position of the data glasses in relation to a defined reference point and additionally or alternatively represents a movement of the data glasses. The method also includes a step of applying a function rule for controlling a function of the data glasses by using the sensor signal.
