Description

The invention relates to a method for supporting a user in solving a technical task, in particular when solving a technical task using instructions, and a method for optimizing instructions for solving a technical task.

Technological background

Instructions, including assembly, operating and other forms of instructions, are conventionally provided to a user in the form of a printed booklet or as a PDF file. These are text and/or image based instructions. Currently, some manufacturers only provide a QR code and a user can then download the instructions themselves from the Internet. It also happens that manufacturers of various products provide videos instead of operating instructions or assembly instructions that are intended to support a user in operating a product or assembling the product.

Instructions are often of poor quality and a user often has to rely on the assistance of third parties when assembling products or putting products into operation. Videos alone are not a solution either, as a user often cannot immediately find what they are looking for.

The object of the present invention is therefore to overcome or at least minimize the disadvantages of the prior art and to provide improved instructions.

Summary of the invention

The above-mentioned object is solved and the disadvantages of the prior art are overcome or at least minimized by a method, a device and a system for supporting a user in solving a technical problem and a method for optimizing instructions for solving a technical problem according to the present Epiphany. In particular, this task is solved by a method, a device and a system with the features of the independent claims.

Thus, a first aspect of the disclosure relates to a method for supporting a user in solving a technical task, comprising the step of displaying instructions on a display means, the instructions comprising a plurality of instruction elements. The instructions are, in particular, text and/or image-based assembly, assembly or maintenance instructions, preferably instructions for solving or working on a technical problem. The instruction elements preferably illustrate individual steps of the construction, assembly or maintenance process, for example in the form of sketches or line drawings, whereby there is usually a continuous sequence of instruction elements (for example by numbering) to guide the user through the individual steps to carry out instructions. The display means is preferably a screen, for example a screen of a computer, PC, smartphone, tablet or the like. The instructions are displayed, for example, on a page basis or by scrolling through the instructions.

The method according to the disclosure further includes the step of displaying linking indicators related to one of the plurality of guidance elements on the display means, each of the linking indicators being coupled to at least one predetermined location of a media file. In other words, a large number of linking indicators are displayed, with one linking indicator preferably being displayed in relation to an instruction element. The reference allows a user to preferably clearly assign the linking indicator to an instruction element. The linking indicator is coupled to the at least one predetermined position of a media file by electronic data processing and/or programming.

In a further step of the method according to the present disclosure, user input is received to select one of the linking indicators. The user input is preferably carried out directly on a touch-sensitive display device or indirectly by using an input device, such as a pointer, a mouse, a keyboard or the like. The input is also preferably carried out via voice input, eye tracking, or the like.

In the method according to the disclosure, at least a portion of a media file coupled to the selected link indicator is also loaded into a volatile memory. The volatile memory is a volatile memory connected to the display means and loading is preferably carried out via a communication interface, particularly preferably via a wireless communication interface. The media file loaded at least in sections is displayed in the method according to the present disclosure according to the position of the media file coupled to the selected linking indicator. This is preferred a representation of the media file from the linked position of the media file or the representation of a section of the media file corresponding to the linked position.

In the method according to the invention, the associated device and the system, an instruction element of an instruction is advantageously coupled to at least one position of a media file via link indicators. A user is thus reliably, repeatably and objectively supported in completing the instructed technical task by establishing a link between a specific instructional element of the assembly instructions and a specific position of the media file, for example an assembly video, which allows the user to target the media file in a targeted manner access.

A user sees instructions in front of them on a display, can page back and forth in the instructions or scroll through the instructions. There are linking indicators on these instructions, preferably represented by pulsating dots or flashing dots, also known as “pulsing bubbles” or “hotspots”. If a user selects one of these points, then in addition to the instructions, an appropriate video, image, audio message or 3D animation appears, with the media file being displayed according to the position corresponding to the selected linking indicator. This is to be distinguished from a display position of the media file within the instructions.

In contrast to conventional instructions, where a user only has a text- and / or image-based instruction or, alternatively, a video in front of him, in the method according to the invention a user receives the information of a text- and / or image-based instruction and additional information that matches this the coupling with video, audio or image information displayed according to the positions coupled to the linking indicator. If a user has a problem with a complicated part of the instructions during assembly, he or she can simply select a flashing point in exactly this complicated part and a suitable video or a more detailed image will be opened, whereby the link indicator not only points to a suitable one media file is coupled, but also to a predetermined position of the media file.

The media file is preferably a video file, an audio file, a three-dimensional computer graphic and/or an image file. Three-dimensional computer graphics can be, for example, Computer Generated Imagery (CGI).

Preferably, the predetermined position of the media file includes a temporal position and/or a spatial image position for video files, a temporal position for audio files, and a spatial image position for image files and/or three-dimensional computer graphics.

Preferably, the location of the media file is a location within the media file. Preferably, the predetermined position of the media file for video files and/or for audio files is a temporal start position. This is therefore the beginning of the media file.

The linking indicators preferably include a link structure to the respective coupled position of the media file, the link structure coupling a position of the linking indicator in the instructions, the media file and the position of the media file. For example, the media file is stored on storage on a server. The positions of the link indicator in the guide and the position (in) the media file are stored in a database. The link structure couples the two database objects with the media file on the server. By selecting a corresponding link indicator, a specific position in a specific media file can be opened and displayed.

Preferably, at least a plurality of link indicators are coupled to a media file, with different link indicators of the plurality of link indicators being coupled to different positions of the media file. For example, a variety of information can be conveyed in a video and a user can use the various link indicators to jump to different places in the video. Since the media file is only loaded in sections, resources such as transmission bandwidth can be saved. This also advantageously saves storage space because the media file does not have to be stored multiple times (for example on the server). In addition, the creation of the media file is independent of the structuring of the instructions into individual instruction elements, since the assignment of different instruction elements to different positions can advantageously be carried out variably. For example, different instructions may have different numbers of instruction elements and the same media file may accordingly be provided with different numbers of link indicators.

Preferably, each of the link indicators is linked to exactly one media file. In other words, in this case everyone will Selecting a different link indicator also opens a different media file at a predetermined position. In some cases, it may be easier to have many space saving media files loaded into volatile memory one at a time.

Alternatively or in addition to the previous variant, each of the link indicators can also be directed to multiple media files. Several different types of media files can be displayed or several different media files of the same type.

Preferably, the linking indicators are displayed in spatial proximity to one of the plurality of instruction elements and/or a visual link between the linking indicators and one of the plurality of instruction elements is additionally displayed on the display means. Here, the linking indicators are either shown directly at the location of the instruction elements or the linking indicators are shown at another location in the instructions shown and are linked to the corresponding instruction element, for example, with a symbol, preferably an arrow or the like. If the linking indicators are shown at a different location in the instructions shown, the advantage is that in complicated instructions, no important information is covered up by the linking indicators.

The user input for selecting one of the linking indicators is preferably received via an input device, the input device comprising a touchscreen, a mouse, a gamepad, a joystick and/or a motion detection device. A user can click on the linking indicators using a variety of different input types.

Additionally, the method may further include the step of collecting user information, wherein the user information relates to linking indicators and/or critical instructional elements. Users can submit user input regarding a position of a desired linking indicator in the assembly instructions. The user input may also concern a type of desired media file associated with the desired linking indicator. Users can directly create new link indicators in the instructions presented or select the instruction element for which they believe information is missing. Users can also select the type and/or type of media file and select the predetermined position of the media file in their user information.

A second aspect of the disclosure relates to a method for optimizing an instruction, comprising the step of segmenting the instruction into a plurality of instruction elements. The instructions are, in particular, text- and/or image-based construction, assembly or maintenance instructions, preferably instructions for solving or working on a technical problem. The instruction elements preferably illustrate individual steps of the construction, assembly or maintenance process, for example in the form of sketches or line drawings, whereby there is usually a continuous sequence of instruction elements (for example by numbering) to guide the user through the individual steps to carry out instructions.

The method according to the disclosure further includes the step of identifying a plurality of critical guidance elements. Critical instructional elements are instructional elements of the multitude of instructional elements for which a reference to a linking indicator is objectively necessary. In other words, critical instruction elements are particularly complicated or poorly presented instruction elements for which a user requires additional support. The critical instruction elements are also preferably those elements that have been identified as critical instruction elements based on user input.

In a further step of the method according to the present disclosure, the critical instruction elements are coupled to a predetermined position of at least one media file. The critical linking indicator is coupled to at least one predetermined position of a media file by electronic data processing and/or programming. In the method according to the disclosure, linking indicators related to the critical instruction elements are also inserted into the instruction to create an optimized instruction. An optimized guide is accordingly a guide with guide elements that further has link indicators that are coupled to a predetermined location of a media file.

In the method according to the invention, a classic instruction with text and/or image elements is first segmented into instruction elements. A decision is then made as to which of these instruction elements requires further information. These instructional elements are then identified as critical instructional elements. These critical instruction elements then receive a coupling with a predetermined position of at least one media file and ent speaking linking indicators, which create the link to the media file, and are then inserted into the instructions with reference to the critical instruction elements. The result of the method according to this aspect of the present disclosure is therefore an optimized instruction with the advantages discussed above.

Preferably, different critical instruction elements of the plurality of critical instruction elements are coupled to different locations of the media file. Since the media file only has to be loaded in sections, resources such as transmission bandwidth can be saved. This also advantageously saves storage space because the media file does not have to be saved multiple times. In addition, the creation of the media file is independent of the structuring of the instructions into individual instruction elements, since the assignment of different instruction elements to different positions can advantageously be carried out variably. For example, different instructions may have different numbers of instruction elements and the same media file may accordingly be provided with different numbers of link indicators.

Also preferably, various critical instructional elements are coupled with various media files. In certain cases, it may be beneficial to pair different media files instead of changing the location within a media file. This may be the case, for example, if a media file is too large to store and therefore needs to be split. For example, due to the file system used.

Preferably, the segmentation is carried out using image analysis, artificial intelligence (AI), meta-information and/or predefined numbering of the large number of instruction elements. A user may have previously numbered the elements of the instructions and the method segments the numbered elements of the instructions into instruction elements accordingly. Meta information can be previously defined by a user, with the method dividing the instructions into instruction elements based on this meta information. A trained artificial intelligence can independently divide the instructions into instruction elements. Finally, image analysis can segment the instructions; for example, image analysis can identify gaps between assembly steps in assembly instructions and thus define each assembly step as an instruction element.

Preferably, the plurality of critical instruction elements are identified using artificial intelligence.

Preferably, the artificial intelligence is trained using instructions and instructions relating to user information and/or optimized assembly instructions. As mentioned above, user information may include information about missing linking indicators or instructional elements to which linking indicators would be optimal to refer. The usage information therefore identifies critical instruction elements, for example the positions of critical instruction elements in the instructions. This user information is given to the artificial intelligence together with classic, non-optimized instructions. Feeding the AI with this data is repeated very often, resulting in a trained AI that independently recognizes critical instruction elements in instructions entered into the trained AI. A similar result is achieved when a user optimizes a large number of instructions by hand and gives these optimized instructions to an AI. Here, too, the AI is trained using assembly instructions and associated critical assembly instructions, so that over time the AI “understands” which instruction elements are critical in instructions entered into the trained AI.

The artificial intelligence is also preferably trained using a media file and assembly instructions. The Kl recognizes similarities to certain instruction elements in a media file, for example in the content of a video. This makes it possible to see when a chair is being assembled when a chair is assembled. The recognized positions in the video are then linked to the corresponding instruction elements of the instructions.

Preferably, the linking indicators are inserted in spatial proximity to one of the plurality of instruction elements and/or in addition a visual link is inserted between the inserted linking indicators and one of the plurality of critical instruction elements. Here, the linking indicators are either inserted directly at the location of the instruction elements or the linking indicators are inserted at another location in the instructions and, for example, linked to the corresponding instruction element using a symbol, such as preferably an arrow. If the link indicators are inserted at a different location in the instructions, the advantage is that in complicated instructions, no important information is obscured by the link indicators.

A third aspect relates to a device comprising at least one memory and at least one processor, the device being set up to carry out one of the methods described above in accordance with the present disclosure.

A further aspect relates to a system for supporting a user in solving a technical task, comprising a mobile user terminal and a server, wherein the mobile user terminal comprises an input device and a display means and wherein the mobile user terminal is set up for the steps: displaying assembly instructions on the Display means, wherein the assembly instructions comprise a plurality of instruction elements, displaying linking indicators with respect to one of the plurality of instruction elements on the display means and receiving user input via the input device for selecting one of the linking indicators. The mobile user terminal is further set up for the step of loading at least a portion of a media file coupled to the selected link indicator into a volatile memory. The mobile user terminal is further set up for the step of displaying the media file loaded at least in sections according to the position of the media file coupled to the selected linking indicator.

Furthermore, the server is set up for the steps: coupling at least one predetermined position of a media file to each of the linking indicators and transmitting at least the portion of the media file coupled to the selected linking indicator to the mobile user terminal.

Furthermore, the server or the mobile user terminal is set up for the step of determining the predetermined position of the media file based on the received user input.

The mobile user terminal is preferably a computer, a PC, a smartphone, a tablet or the like. However, the invention is not limited to this.

Further preferred embodiments of the invention result from the remaining features mentioned in the subclaims.

Unless stated otherwise in individual cases, the inventions can be advantageously combined with one another. In particular, representations and descriptions of preferred refinements and embodiments of the method can always be transferred accordingly to the devices and the system and vice versa.

Detailed description of the invention

The following is, with reference to 1 and 2 , a preferred embodiment of a method 100 for supporting a user in solving a technical task is described using a concrete example.

Instructions 201 are displayed to a user on a display means 340 (step 101 in 1 ). This instruction 201 contains a variety of instruction elements (step 202 in 1 ). In 2 The instruction elements 202 are the sequence of images in assembly instructions. The sequence is shown by dashed arrows. Linking indicators 203 are also shown in the instructions 201 (step 102 in 1 ). In 2 these link indicators 203 are represented by black dots. One of the linking indicators 203 is located further away from the instruction elements 202 and its association with one of the instruction elements is shown with a black arrow 206. Each of the linking indicators 203 is coupled to at least one predetermined position 204 of a media file 205. If a user now clicks on one of these points 203, this user input is received (step 103 in 1 ). At least a section of the selected link indicator 203 is coupled Media file 205 is loaded into the volatile memory of the device 300 used, for example a desktop PC (step 104 in 1 ). The loaded section of the median file 205 is then displayed on the display means 340 (step 105 in 1 ).

A user is therefore shown instructions 201 and various multimedia elements 205 on a display area 340. Instruction elements 202 and possibly also instruction pages are linked to predetermined positions of the multimedia elements 205. For example, if a sofa needs to be assembled, a user is shown assembly instructions 201 together with an assembly video 205. By selecting a link indicator 203 of the various elements in the assembly instructions 201, the user can jump between different videos 205 or different places in a video 205, these places or the different videos 205 exactly matching the element in the assembly instructions 201. Likewise, by selecting one of the points 203, a user can display all components relevant to the associated critical instruction element or have preferred tools displayed using a corresponding media file.

3 shows an embodiment of a device 300 according to the invention for supporting a user in solving a technical task. This device includes at least a memory 310, a processor 320, an input device 330 and a display means 340. The memory 310 includes a volatile memory and a non-volatile memory. The device 300, or the processor 320, is set up to carry out the method 100. The device 300 receives user input via the input device 330 and displays instructions 201 and multimedia elements 205 on the display means 340. The linking indicators 203 with instruction elements 202 are also displayed on the display means 340. The device 300 stores the media files 205 on non-volatile memory and loads portions thereof into volatile memory. Link structure information is stored in a database on the device 300.

The following is, with reference to 4 , 5 and 6 , a preferred embodiment of a method 400 for optimizing instructions is described using a concrete example.

In a first step 401, an instruction 201 is segmented into a large number of instruction elements. Different methods can be used for segmentation. For example, if the instructions 201 are assembly instructions, then each assembly step can be an instruction element. In a second step 402, the plurality of instruction elements are analyzed and a plurality of critical instruction elements are identified. These critical instructional elements may be instructional elements that urgently need a linking indicator. For example, the critical instruction elements represent particularly difficult assembly steps or represent a specific component for the first time. Each of these critical instruction elements is coupled to a position in a media file in a third step 403. This could be, for example, an explanatory video for the particularly complicated assembly step or an image of a list of screws. In a fourth step 404, link indicators are now inserted in the instructions with reference to the previously identified instruction elements. The link indicators include a link structure to the respective linked position of the media file. This creates optimized instructions.

The analysis of the instructions and the identification of the critical instruction elements is carried out here 6 via trained artificial intelligence. The training of artificial intelligence is in 5 shown.

5 shows that an artificial intelligence is fed with instructions 201 and information 501 about critical instruction elements. It is clear here that the artificial intelligence is not only fed with a single instruction 201 and information 501 about critical instruction elements, but rather a large number of instructions 201 and associated information 501 about critical instruction elements are used for this purpose. The more the AI is trained, the better the resulting trained AI 503 is. The trained AI recognizes patterns in the training data and can independently identify critical instruction elements 203 in instructions 201. For example, the information 501 about critical instructional elements was previously captured as user information.

6 shows how the trained Kl 503 is applied to a not yet optimized instruction 201. The trained Kl 503 uses the training data to identify critical instruction elements in the non-optimized instruction 201. This allows the method 400 to insert link indicators 203 with reference to the critical instruction elements found by the AI into the instruction 201 to create an optimized instruction 601.

7 shows a system for supporting a user in solving a technical task as an alternative to the device 3 . Not all steps of the procedure for supporting a user in solving a problem are covered here technical task of instructions is carried out on a mobile user terminal 300, but certain steps are taken over by a server 700. The server 700 in this case includes the database and the non-volatile memory in which the media file(s) are stored. The server couples the predetermined position 204 of a media file 205 to each of the linking indicators 203 and transmits at least the portion of the media file coupled to the selected linking indicator to the mobile user terminal 300. Wherein either the mobile user terminal 300 or the server 700 the predetermined position 204 of the media file 205 based on received user input. The required information can either be on the database of the server 700 or, for example, as HTML code directly in the link indicator.
