Description

[0096] In the drawing:

[0097] FIG. 1: shows a schematic side view of one exemplary embodiment of a system according to the invention;

[0098] FIG. 2: shows a schematic front view of the embodiment from FIG. 1 of the mobile terminal;

[0099] FIG. 3: shows a schematic perspective view of a virtual representation of an object to be cleaned; and

[0100] FIG. 4: shows an exemplary sequence of a method according to the invention.

[0101] FIG. 1 shows by way of example one embodiment of a terminal 3 according to the invention. A cleaning person 1 as an example of a user here is wearing the mobile terminal 3 in the embodiment of smartglasses comprising a camera 5 as an example of an optical sensor according to the invention and a UV light source 7 as an example of a radiation source, and furthermore comprising a further additional UV light source 8 as a further radiation source, a further additional sensor 4 and a further additional camera 6.

[0102] As is readily evident in FIG. 1, the additional UV light source 8 can be positioned as desired in space and, by way of the additionally emitted light, can generate further reflections that can be detected by the camera 5 or the additional camera 6.

[0103] FIG. 2 shows by way of example the mobile terminal 3 in the embodiment of smartglasses comprising the cameras 5, 5′ and UV light sources 7, 7′, and also a data processing device 10 and a rechargeable battery 12, with the display devices 9, 9′ and also an area 11, 11′ to be cleaned and the impurity 13, 13′ furthermore being shown.

[0104] Various work modes are conceivable here. The smartglasses can display a “virtual” reality as smartglasses, but they can also preferably be embodied as augmented reality (AR) glasses. In this case, the reality seen by the user is superimposed with additional information, as described above.

[0105] In this case, provision can be made in particular for the camera 5 and the additional sensor 4 to detect data in real time. From these data, the data processing device 10 generates a presentation of the contamination, as shown by way of example in FIG. 3 below, and projects this and optionally additional information for the cleaner into the smartglasses 3, embodied as AR glasses, into the field of view during cleaning. In addition, these generated data can be used for documentation and/or for optimization of the cleaning or work sequences, etc.

[0106] During the entire process, the smartglasses or the augmented reality glasses can inspect, document and evaluate the cleaning process and the result.

[0107] If a system according to the invention is used in a hospital, for example, then over and above the cleaning personnel the system has great benefits e.g. for nursing staff, whose occupation causes them to be in (skin) contact with humans, but also for use in hygiene inspections, etc.

[0108] FIG. 3 shows by way of example a dirty area or area to be cleaned having the impurities 13, 13′, 13″ and 13′″. The impurity 13 is an impurity that is displayed directly by way of reflected UV light that is visible to the user in the smartglasses 3.

[0109] The impurity 13′ is an impurity that is marked by a circle. Of course, other kinds of highlighting such as arrows, indications, etc., are also conceivable, where the kind of highlighting can be appropriately defined by a person skilled in the art depending on the application.

[0110] The impurity 13″ is a virtual representation of an impurity that is marked by crosses. It goes without saying that such “virtual” impurities can also be highlighted using graphical elements in accordance with 13′.

[0111] Primarily if the smartglasses 3 comprise a UV filter in order to protect the user's eyes, said filter completely or partly filtering UV light, exclusively virtually calculated representations of impurities are displayed to the user.

[0112] In this case, but also in accordance with the further embodiments of the present invention, impurities can be displayed by way of chosen virtual representations thereof.

[0113] A further alternative form of presentation of an impurity is impurity 13′″. In this case, the individual impurity is not displayed, rather a calculated severely dirty region is highlighted as a complete region graphically on a surface to be cleaned.

[0114] It is evident here to a person skilled in the art that the various forms of presentation of impurities can be generated by the data processing device 10 and displayed on the display device 9, 9′ individually and in any possible combination.

[0115] FIG. 4 schematically shows the method steps according to the invention for operating a system or a mobile terminal, wherein step 100 represents activating the UV light source, step 110 represents detecting the UV light of the UV light source reflected from the surroundings by means of the camera or a sensor; and step 120 represents evaluating the detected camera and/or sensor data in the data processing device and generating a virtual representation of contaminants, step 130 represents displaying the virtual representation of the contaminants on a display device, in particular on smartglasses, wherein the displaying is displayed in particular in the form of augmented reality as additional information for a user, step 150 represents documenting and recording the changes in the space detected by the camera or the sensor and/or the work carried out by the user, wherein step 140 denotes displaying work instructions and/or information in parallel with or as an alternative to displaying the virtual representation of contaminants, and step 160 denotes disinfecting an object and/or a spatial region by means of one of the UV light sources of the system or of the mobile terminal.

[0116] The features of the invention disclosed in the above description, the claims and the drawings may be essential to the realization of the invention in its various embodiments both individually and in any desired combination.
