- One or more of the household appliances can be controlled by means of an interaction device.
- the interaction device can be set up to determine a spoken instruction and to control an assigned function of one of the household appliances.
- US 2017 361 468 B2 describes a mobile interaction device that can be attached to different household appliances.
- interaction device is not suitable for all real applications. For example, a distance from which a spoken instruction is accepted is usually limited. Interaction devices are usually relatively expensive and inflexible.

- the interaction device can be addressed in an improved manner from an enlarged distance range.
- the interaction device can be made responsive from an area whose size is that of a conventional one Apartment or a normal room corresponds to an apartment or a residential building.
- the control can in particular relate to a domestic appliance.
- a function of the domestic appliance is preferably triggered or an operating parameter of the domestic appliance is provided or changed on the basis of the spoken instruction.
- the household appliance can for example comprise a stove, a refrigerator, an extractor hood or an oven.
- the control relates to a function of the Inter reliesein direction itself, for example, when the interaction device displays a cooking recipe step by step, provides information on a spoken question or establishes a telephone connection to a predetermined participant.
- the interaction device can serve as an interface between the person and any number of devices or information stores.
- a directional characteristic of the first microphone for acoustic scanning in the close range and a directional characteristic of the second microphone for acoustic scanning in the far range of the interaction device are set up. Due to the different configurations of the two microphones, the area can be scanned acoustically in an improved manner.
- a sound source in the near range can be scanned preferably by means of the first microphone and a sound source in the far range is preferably scanned by means of the second microphone. Unwanted sound sources in the other area can be suppressed better.
- the directional characteristic of the first microphone can, for example, be relatively circular or spherical and that of the second microphone can be relatively heart-shaped or kidney-shaped. In other words, a directivity of the second microphone can be stronger than that of the first microphone.
- the first microphone can have an improved sensitivity with respect to a sound source in the close range, while the second microphone can better detect sound from a sound source arranged in the far range while masking out interfering noises. As a result, sound sources at different distances can be scanned and distinguished from one another in an improved manner.

- sealing means e.g. Sealing rings to protect the interaction device from splashing water and standing water on the floor space. In this way, the electronics in the Inter relieseinrich device are protected from moisture.
- the processing device can be set up to determine the direction of a source of the spoken instruction. This can be done in particular on the basis of phase shifts between signals of differently oriented second microphones. By processing signals from several microphones, the influence of another sound source can be reduced. In addition, a distance from the source of the spoken instruction can be determined or at least estimated on the basis of signals from the microphones.
- a position of the source of the spoken instruction can be determined with respect to the interaction device and further optionally the position can be checked for plausibility with respect to a boundary of a surrounding space will.

- the invention described here can be particularly advantageous when a user already has a mobile device such as a smartphone or a tablet PC. These devices are usually quite expensive and quickly become obsolete, but they are relatively powerful. An average user would also like to use these devices for cooking by displaying the recipe steps on these devices.
- the microphones on smartphones are set up in such a way that they prefer to pick up acoustic signals from the immediate environment, but are not very sensitive to voice input from a distance.
- it can always happen that liquids are present on the surface or splash onto it. Since the user often moves around while cooking, it can happen that he cannot see the screen of the mobile device clearly from all positions.
- the interaction device described here can now contribute to solving these problems. It can be optimized in order to be able to understand spoken instructions well from a distance. It can provide a shelf for the mobile device so that the screen can be easily seen by the user at all times. For this purpose, the user can be located and the screen rotated accordingly. In addition, a certain distance between the mobile device and the floor space can be achieved in order to protect the mobile device from moisture.
- the interaction device does not need an expensive processor because the processor of the mobile device can be used. In this way, the mobile device is purposefully supplemented by the properties that make it particularly suitable for supporting a cooking process in the kitchen.
