Technical Field
The invention relates to a hand-held device comprising at least one spectrometer with at least one radiation source and at least one radiation detector, a microscope camera and a microcomputer, wherein the microcomputer has an interface for wireless data communication and a data memory. The invention further relates to a method for operating a handheld device. The invention further relates to a system having the handheld device and to a method for operating the system.
Background
At present, the wear of the individual items of laundry is not usually systematically detected in the household. In laundry and/or in rental clothing services, for example, individual items of laundry are marked specifically or provided with a code similar to a bar code. In this case, the reading is usually carried out with a high expenditure of labor, since it is not always possible to directly detect or read the text and/or the code placed on the washing in a specific position.
An alternative may also be, for example, an RFID chip. The chip enables information about the individual items of laundry to be transmitted also remotely and without direct line-of-sight contact. However, the disadvantage of these chips is that they have to be placed on each individual item of laundry. This is partly accompanied by high costs. Furthermore, equipping individual items of laundry with RFID chips can also give rise to an unpleasant sensation of "monitoring" or "control".
It is therefore desirable that the treatment of laundry in the household can be improved and that the effect of the treatment on the properties of the laundry can be detected in a simple manner.
Household appliances and methods for improved laundry treatment are already known.
Publication WO 2001/046509 a1 describes an appliance for treating textiles with a device for identifying properties of the textiles, wherein the device comprises at least one transmitting element for transmitting electromagnetic radiation and at least one receiving element for receiving electromagnetic radiation, and an evaluation circuit connected to the receiving element, wherein radiation transmitted by the transmitting element and reflected and/or transmitted by the textiles can be received by the receiving element and can be evaluated in the evaluation circuit.

A limiting aperture for limiting the effective diameter of radiation impinging on the diffraction element is provided between the sample space and the diffraction element.
Publication EP 1242665B 1 describes an appliance for treating textiles by means of an evaluation circuit for identifying the textile type and/or the moisture of the laundry. The device comprises a transmitting element for transmitting electromagnetic radiation, a receiving element for receiving electromagnetic radiation, and an evaluation circuit connected to the receiving element. A method for identifying characteristics of a textile article, for example in a washing machine or a laundry dryer, is also described.
Publication DE 102013104976 a1 describes a system comprising a household appliance, a mobile communication device and at least one RFID transponder spatially assigned to the household appliance. The communication device can read the identification of the RFID transponder located in the detection area of the communication device, and the read identification can invoke a predefined action in the memory of the communication device.
Publication DE 102014112375 a1 describes a device for controlling a household appliance, wherein the device has the following features: an interface for reading in image information from a sensor array of a display unit of a household appliance, wherein the sensor array comprises a photosensor which is a constituent of an image point of the display unit; and an evaluation device for providing a control signal for controlling the household appliance by using the image information.
The publication DE 102014102531 a1 describes a method for operating a household appliance, in which images of encoded information are recorded by means of a mobile telephone comprising a camera and the encoded information or useful data contained by the encoded information are transmitted to the household appliance, wherein the household appliance extracts the useful data contained by the encoded information from the encoded information and receives the useful data in an internal memory or receives the directly received useful data in the internal memory, wherein the household appliance interprets the useful data as an automatic control program and processes it into the automatic control program.
