Description

TECHNICAL AREA

The present invention relates to a teaching/teaching system with a number of analog (print) media and with a server and with a particular Internet or WLAN-based communication interface to a large number of mobile terminals that can be used in the system, each with an optical detection device, the analog ( Print) media are each equipped with QR codes and can be correlated/correlated with content that can be stored on the server via the QR codes and can be assigned to at least one group of people by the system. Furthermore, the present invention also relates to the implementation of a computer program product for implementing a method for providing content that is/can be stored on at least one server with individual access authorization, with at least one analogue (print) medium and at least one mobile terminal device with an optical detection device interact with each other in a teaching/teaching system, wherein the at least one analog (print) medium is equipped with QR codes and is correlated with at least one QR code-based access authorization to content (content) that is/can be stored via the QR codes /will, in particular for the administration and assignment of digital content to individual print media or users or user groups. Last but not least, the present invention also relates to the use of such a system or a computer program designed for it based on at least one group-specifically created digital twin that maps the analog (print) media used by means of the QR codes. In particular, the invention relates to a device and a use according to the preamble of the respective independent claim.

BACKGROUND OF THE INVENTION

The use of on the one hand analog and on the other hand digital media/content can already take place using systems that connect both media with one another. In modern teaching/teaching systems, digital media (multimedia) content is becoming increasingly important, and classic print media are becoming less important. Nevertheless, classic print media (especially the classic textbook or learning exercise booklet) are still indispensable, especially in the younger years of school education, e.g. in connection with learning writing skills (handwriting) and mother tongue/foreign languages. In contrast to classic print media or school exercise books, for example, which can usually be assigned to a specific person (owner, proprietor), the challenge with digital content is to release it at the right time for the intended person or for the authorized groups of people (or not to be released, i.e. to restrict their use or view through access restrictions). It should also be possible to distinguish between (read) access and access (editing/change authorization).

Up to now, teaching/teaching institutions have had to put in a lot of effort in order to be able to provide attractive print media on the one hand and up-to-date digital offers on the other. This also creates a lot of additional work for the teachers, because on the one hand they have to familiarize themselves with the new digital offers and possibilities, on the other hand at least some of the teaching content, which was previously conveyed primarily via classic print media, must now also be conveyed via digital channels. In this respect, there is great interest in ways of simplifying the teaching of teaching content using both classic print media and modern digital methods in combination with one another, or at least enabling it to be more efficient than before, and also the use of digital content (content) simplified for selected people (groups) and designed to be as safe as possible.

According to the state of the art, access to digital content (content) is usually secured by password protection, which, however, usually requires the user to register with the relevant service provider (user account, login). In connection with teaching/teaching projects in particular, there is interest in alternative ways of making the content available, in particular if possible without the need for a user account or without a login action on the part of the user. This also applies in particular to use by large groups of people (e.g. schoolchildren, especially children/adolescents) who should disclose as little personal data as possible or, ideally, no personal data at all on the Internet, in particular to avoid any risk of data misuse/theft, including on the part of school management or a to be able to minimize educational institutions.

The use of QR codes for providing and managing media (multimedia) content, such as multimedia content combined from audio, image and/or video data, based on print media is already known. The publication can serve as an example DE 10 2019 124 154 B4 are called, which describes a multimedia book system, by means of which a correlation on the one hand QR codes can be done with certain page areas in the book or print medium and on the other hand a freely definable file type can also be correlated with the respective QR code. The QR codes can be linked to individual multimedia content (in the sense of an example of storage space using the connection provided by the QR code). The multimedia book system described there is primarily intended for use by individuals, in particular in the sense of a memory book or personal diary or an experience report that is primarily only created/usable for a specific person.

Based on the state of the art, there is a need for systems and methods by means of which access/access authorizations in a system, in particular a teaching/teaching system, for individual (multimedia) content can be issued and managed in the simplest and most secure manner possible, especially with different levels of access authorization. Last but not least, there is an interest in a safe and simple and preferably also time-variable/ adjustable assignment of access authorizations, in particular hierarchically classified.

SUMMARY OF THE INVENTION

The task is to provide a teaching/teaching system for the provision of content that can be stored or retrieved on at least one server with individual/individualizable access authorization, in particular for the communication and processing of teaching content, with which the respective access authorization can be granted and managed in a simple and secure manner and with which the desired content can be entered and optionally edited in the simplest and most secure way possible. It is also a task to design such a system in such a way that the content can be stored with a comparatively good security standard and protected against unauthorized access, in particular with/with at least one parameter that varies over time, with any required/desired use/application of person-specific personal data should meet high data security standards.

This object is achieved by a teaching/teaching system according to claim 1 and by uses according to the independent use claims and by a computer program product according to the further independent claim. Advantageous developments of the invention are explained in the respective dependent claims. The features of the exemplary embodiments described below can be combined with one another unless this is explicitly denied.

A teaching/teaching system is provided with several analog (print) media and with a server and with a particularly Internet or WLAN-based communication interface to a large number of mobile end devices that can be used in the system, each with an optical recording device, with the analog (print) ) Media are each equipped with QR codes and can be correlated/correlated with content that can be stored on the server via the QR codes and can be assigned to at least one group of people by the system; According to the invention, it is proposed that the teaching/teaching system for the individual analog (print) media has at least one first QR code/code and at least one second QR code linked thereto, the first QR code/code and the at least one second QR codes are each provided in/on the same (print) medium, the individual second QR codes also being predefined in the system in such a way that they are/can be linked to at least one specific of the analog (print) media, in particular also to a specific page of the (respective) analog (print) medium (especially book page) that a link/correlation of a/the respective end device takes place via the first QR code/code to the second QR code and the content stored above it if the first QR -Code/code is scanned using the appropriate terminal device or (preferably a master code configured as a number/digit combination) is entered manually and if at least one of the linked en second QR code is scanned using the corresponding end device, with a graphical user interface/surface being provided on the system side, by means of which a respective user can at least scan/enter the first QR code/code and/or the second QR code on the system side is/is requested to either initiate a personal/user-specific registration process using the corresponding end device based on person-specific registration data (in particular registration data in the form of user name and password, preferably a password that is external to the system or assigned by the system and cannot be defined independently) or a non-personally specific one using the corresponding end device to initiate system use, whereby depending on this personal (un)specific registration (or depending on the user specification) on the system side a/the entry/access authorization specifically for the at least one terminal or can be assigned individually for the corresponding user or the registered person, in particular at least one first (relatively stronger) entry/access authorization for a person-specific registered user and at least one second (relatively weaker) entry/access authorization for a person-unspecific user (not in System registered/logged in user). In particular, this also simplifies the coordination of the use and communication of digital content with optional access/access restrictions for a large number of people and different groups of people, especially in connection with analogue (teaching) content.

“Linked” is to be understood here in particular as a relation between first and second QR codes and QR codes with predefined/predefinable access authorizations, in particular also via at least one identification feature of a respective QR code, with the link being/are predetermined by the system can (optionally is predefined or can be stored in an adjustable/adaptable manner in the system), in particular for the definition of an individual (e.g. also time-limited or variable) access authorization for individual persons and groups of persons (or a degree or a strength or a scope of an access authorization) . "Linking" is to be understood in particular as a coordination and administration of individual print media/books of a comparatively large group of people (in particular at least one school class).

In this context, “correlated” means in particular an assignment of individual analog media or print media or of individual (second) QR codes to digital content; “correlated” here also means in particular an assignment of specific, predefined mobile end devices with/to at least one first (QR) code; in this respect, the term "correlated" also refers to a relationship between content and users, which can be created by means of the codes (and by means of the system-specific linking of the codes to one another). "Correlation" is also to be understood in particular as an assignment of users and end devices to individual print media.

"User-specific" here means a specific release for a predefined end device. "Person-specific" is to be understood here in particular as a specific release for a predefined end device, for which a (single) person has to log in using specific login data in order to obtain the system-side release for access to the content stored via the second QR code obtain.

The device for scanning the QR codes, which is generally described here as a “mobile device”, can also be a device in general, in particular any device with a communication interface to the Internet; the mobility of the end device is less relevant here; Based on the present disclosure, it is clear to the person skilled in the art that reference to mobile end devices in particular describes an obvious use by smartphones, but that any other type of end device with a QR code detection unit (in particular camera, scanner) and communication interface to the Internet can also be used or to the server or to any other wireless network for the application/implementation of the present invention.

In the present disclosure, a distinction is made between first QR code and second QR code; the first QR code is also called the main QR code; optionally, the function of such a main code provided for the authentication can (additionally or alternatively) also be provided by a master code, which is not designed as a QR code but preferably as a combination of numbers and digits; this also favors, for example, authentication without scanning, ie in the case of a defective camera, and/or facilitates the transfer to an authorized person or person intended to receive the content (eg mail recipient); because a combination of numbers and digits can, for example, be passed on by telephone and can be entered manually; Access authorization can also be activated or extended in a user-friendly manner for a predefined period of time, for example if the smartphone is currently being used for other activities or for reading/recording one of the second QR codes. If a master code is to be provided, this is/is preferably provided together with the corresponding linked first QR code on a sticker or other physical surface (in particular in the form of a number/number combination, for example also optically protected/hidden by a protective film to be rubbed off). Irrespective of whether a main QR code (in the form of a QR code) or a master code (in particular in the form of a combination of numbers and digits) is to be used, these codes are intended for analog media, e.g Print medium or bound to a physical consumer product, eg by being stuck there. To clarify the concept according to the invention, reference is made in the patent claims primarily to the first (main) code in the form of a QR code; however, a person skilled in the art recognizes that the security function can also be ensured by a code, which is not more necessary Way must be designed as a QR code. In this respect, reference is also made at least implicitly to a/the master code within the scope of the present disclosure when the first QR code is mentioned. Depending on the application and the desired security level, the additional or alternative implementation of a master code can be more or less advantageous.

Personified terms, insofar as they are not formulated here in the neuter, can relate to all genders in the context of the present disclosure. Any English terms or abbreviations used herein are industry terms and are familiar to those skilled in the English language. For the sake of completeness, any German-language terms used/usable as synonyms can be given in (brackets) here, or vice versa.

• Personen-/nutzerunspezifisch (anonym), teilweise anonym, nicht-anonym personenspezifisch bzw. nutzerspezifisch. Der für den jeweiligen Anwendungsfall gewünschte Anonymisierungsgrad kann individuell vordefiniert werden.

The present invention enables different types of anonymization and distribution of access rights, for example according to the following three-tier scale:

• Person/user-specific (anonymous), partially anonymous, non-anonymous person-specific or user-specific. The degree of anonymization desired for the respective application can be individually predefined.

According to the prior art, analog content can be expanded by digital content by providing a QR code correlation to the corresponding (optionally changeable) multimedia content in print media at relevant points. Based on this, within the scope of the present invention, for example, classic physical textbooks can be digitally expanded with multimedia content through recordable QR codes attached at certain points in the book, especially with easily monitored/coordinated access authorization for the students to the content. The books are provided with QR codes in advance, with each book being linked (by the system) to a certain subset of QR codes. A textbook (mathematics, German, English, politics, physics or the like) typically has narrowly defined subject areas that have to be worked through during school hours or in a specific school year at a specific school in accordance with a prescribed curriculum. In accordance with these specifications, placeholders or already specific content can now be stored at predefined places in the books via the QR codes. Example: English book for school class 10, exemplary topic "Business in English" or "British economic structure" on the first 20 pages of the book; e.g. on page 5 there is at least one QR code with an exercise to learn specific vocabulary for this topic; e.g. on page 10 at least one QR code is stored, via which mandatory or optional exercises for the corresponding grammar are offered. For example, it can also be very advantageous to provide at least one second QR code that has already been recorded by the system or institution and at least one empty second QR code that can still be individually recorded, especially by a teacher, for each topic or even on each book page. Last but not least, this also enables individualized teaching (in particular additional individualized teaching content) without neglecting the requirements of an educational institution (e.g. the Ministry of Education).

In this context, the present invention also enables the following functionality in particular: In particular, a teacher can store further content behind the respective second QR code (particularly on the at least one server of the present system), e.g. further exercises or other digital learning materials, e.g. current ones Stock market news in English (linked via QR code or uploaded as a video). The corresponding link or multimedia content can be made available to the students directly in the correct thematic context, in particular only in a predefined/predefinable time corridor. For example, the teacher does not have to announce (write on the board) a long, confusing link or similar access option. Or the teacher doesn't need to email students to point out a specific video; in this respect, the teacher does not need any electronic personal (access) data from the students. If required, the system can also be used to show the teacher, for example, which student has done a specific exercise and/or who has already viewed/worked through specific (multimedia) content. This can all be done anonymously. In other words, the teacher can at best find out that e.g. 80% of the students in his class have completed or managed a certain exercise, but not which student has achieved which result. Optionally, the system according to the invention can also enable more person-specific use, depending on personal consent or current legislation (or institutional specifications), in particular according to the following variants: completely anonymous, partially anonymous, direct person-specific digital collaboration between students and/or teachers).

Variant 1 (completely anonymous): The content, information and exercises are only made available in the books or by means of the books and via the QR codes. the Leh rer can store content in the form of videos, images, text or links behind the (second) QR code and make this content available to students. However, the teacher preferably has no insight into whether specific students are consuming or editing content (eg doing exercises) and/or who has viewed video content, for example.

Variant 2 (partially anonymous): The teacher can see how many people/students are viewing/editing the content (in particular have done exercises) and can also determine a success rate, e.g. based on a percentage of how many students from a certain class watched or edited a video or similar content. This type of graduated access/access authorization also enables the teacher, for example, to use an error rate specifically in relation to individual exercises to see in which subject area there are currently difficulties and/or whether there is a high or only low willingness on the part of the students to do the Motivated to work on the subject area, to continue practicing or the like.

Version 3 (non-anonymous), in particular for the purpose of direct cooperation between students and/or students and teachers (in particular in coordination with country-specific data protection regulations): The individual books are individually assigned to the individual students, in particular by all the books in the respective book (second ) QR codes are different (deviate from each other) and/or by using individual first QR codes or master codes. On the system side, a respective QR code can thus be/be associated with a book and a student, with each book used/maintained in the system also being assigned to a specific student on a person-specific basis (system-side documentation). Advantages of this variant: The teacher can provide and query student/person-specific teaching/learning content, e.g. by providing particularly good students with individual support or by working at a higher level of difficulty or by viewing more information (e.g. by providing additional material specific to the person, e.g. further exercises or summaries of previous exercise units, e.g. with photos of the blackboard and/or explanatory videos). In this way, students can be individually supported without the need for one-on-one/private tuition; Especially in the often very inhomogeneous performance profiles at schools and in school coffers, this enables an improvement in the range of courses and a (more targeted) teacher-student interaction. Also, for example, additional tasks for certain students would not have to be discussed in the lesson, but the student could be informed that further content to be processed will be activated or is available. Last but not least, the teacher can use book/person-specific QR codes to directly understand which students are performing well in which subject area.

A/the preferred way of accessing the content stored via the QR codes (or other functions) can also be described as follows under points 1/ and 2/.

• Die vorliegende Erfindung sieht vor, dass ein Lehrer (Lehrkörper oder sonstiges hierarchisch übergeordnetes/vorrangiges Subjekt) eine personenspezifische Anmeldung im System vornimmt, insbesondere basierend auf Benutzername und Passwort. Dazu kann ein Computerprogramm(produkt) bereitgestellt sein, welches diesen personenspezifischen Anmeldevorgang ermöglicht (wahlweise können Schüler oder sonstiges im entsprechenden Kontext hierarchisch untergeordnete/nachrangige Subjekte bzw. nachrangige Nutzer dasselbe oder ein weiteres Computerprogramm(produkt) nutzen, welches einen personenspezifischen Anmeldevorgang jedoch nicht ermöglicht). Systemseitig wird bei personenspezifischer Anmeldung, also für hierarchisch übergeordnete/vorrangige Subjekte, eine Verwaltung und Zuordnung der einzelnen Bücher ermöglicht, z.B. indem der Lehrer einzelne Bücher, die einer bestimmten Schulklasse zugeordnet sind/waren, löschen kann (z.B. für den Fall dass das entsprechende physische Buch verloren gegangen ist) und/oder Bücher neu anlegen bzw. zuweisen kann (im Sinne eines digitalen Zwillings eines körperlichen Buches, für welchen ebenfalls ein Besitzer definiert wird, nämlich ein dem Buch wahlweise personenspezifisch zugewiesener Schüler), was z.B. dann erforderlich wird, wenn eine Schulklasse einen weiteren Schüler zugewiesen bekommt oder ein verlorenes körperliches Buch ersetzt wird). Der Lehrer kann im System alle (s)einer Klasse zugeteilten Bücher erkennen, insbesondere aufgeteilt nach Jahrgang und/oder Themenbereich (Fachbereich). Diese Buchstruktur kann in einer systemseitigen Datenbank insbesondere in der Art eines digitalen Zwillings der Verteilung/Zuweisung der körperlichen Bücher hinterlegt sein/werden, je nach gewünschtem Anonymisierungsgrad auch unter Einbezug personenspezifischer Daten. Der Lehrer hat die Möglichkeit, die jeweiligen zweiten QR-Codes mit Content zu bespielen und zu löschen, wobei sich die Zugangs-/Zugriffsrechte je nach vordefinierter Verknüpfung nur auf einzelne Schüler/Klassen oder auf alle im entsprechenden digitalen Zwilling abgebildeten Bücher/Nutzer erstrecken - dies kann systemseitig vordefiniert werden und insbesondere auch zeitlich variabel eingestellt und angepasst werden. Der Lehrer scannt für die Pflege und Bearbeitung der Inhalte den jeweiligen QR-Code, z.B. betreffend das Fach Englisch, insbesondere Seite 10 des entsprechenden Schulbuches, oder der Lehrer wählt über eine grafische Benutzerschnittstelle (insbesondere über ein/das Computerprogramm(produkt)) das entsprechende Fach sowie die Jahrgangsstufe und die Klasse aus, um in diesem spezifischen digitalen Zwilling dieser Klasse diesen oder weitere einzelne QR-Codes mit Content zu bespielen oder den Content zu ändern oder einen sonstigen darüber hinterlegten Funktionsumfang abzurufen. Insbesondere hat der Lehrer Administratorrechte und kann den jeweiligen Content unbeschränkt einsehen und/oder bearbeiten. Dabei kann der Lehrer wahlweise auch, in Abhängigkeit vom gewünschten/zugestimmten Anonymisierungsgrad, allgemein mit den Schülern oder personenbezogen mit einzelnen Schülern über den digitalen Zwilling kommunizieren. Insbesondere kann/darf der Lehrer auch Content von außerhalb des Systems, z.B. aus dem Internet, hochladen bzw. verlinken (Beispiel: Videos anderer systemfremder Plattformen).

1/ Access to the content stored via the second QR code (or a correspondingly correlated range of functions, e.g. a communication platform) by teachers:

• The present invention provides that a teacher (teaching staff or other hierarchically higher/priority subject) carries out a person-specific registration in the system, in particular based on user name and password. A computer program (product) can be provided for this purpose, which enables this person-specific registration process (optionally, students or other hierarchically subordinate/subordinate subjects or subordinate users in the corresponding context can use the same or another computer program (product), which, however, does not enable a person-specific registration process ). On the system side, with person-specific registration, i.e. for hierarchically superior/priority subjects, administration and assignment of the individual books is made possible, e.g. by the teacher being able to delete individual books that are/were assigned to a specific school class (e.g. in the event that the corresponding physical book has been lost) and/or can create or assign new books (in the sense of a digital twin of a physical book, for which an owner is also defined, namely a student who is optionally assigned to the book personally), which becomes necessary, for example, when a school class is assigned another student or a lost physical book is replaced). In the system, the teacher can see all the books assigned to a class, in particular broken down by year and/or subject area (subject area). This book structure can be stored in a system-side database, in particular in the form of a digital twin of the distribution/allocation of the physical books, depending on the desired degree of anonymization, including personal data. The teacher has the option of loading and closing the respective second QR code with content deleted, whereby the access/access rights only extend to individual students/classes or to all books/users mapped in the corresponding digital twin, depending on the predefined link - this can be predefined in the system and, in particular, can also be set and adjusted to be variable over time. To maintain and edit the content, the teacher scans the respective QR code, e.g. for the subject English, in particular page 10 of the relevant textbook, or the teacher selects the appropriate one via a graphical user interface (in particular via a/the computer program (product)). Subject as well as the grade and the class in order to record this or other individual QR codes with content in this specific digital twin of this class or to change the content or to call up another range of functions stored via it. In particular, the teacher has administrator rights and can view and/or edit the respective content without restrictions. Depending on the desired/approved degree of anonymity, the teacher can also communicate generally with the students or personally with individual students via the digital twin. In particular, the teacher can/may also upload or link content from outside the system, eg from the Internet (example: videos from other non-system platforms).

Interaction can also take place on the institution or system side, in particular with the teacher by providing him with further teaching material or the like, for example further exercises that can be activated for students, or different content such as videos or further learning material. In particular, the teacher can also decide whether or which students should not only have reading rights, but also be allowed to upload content (possibly also topic-specific). For example, the teacher can decide whether a certain student who is particularly good at a particular subject can share a learning strategy or tips with other students via a predefined (second) QR code, i.e. in the sense of an officially approved recommendation by the teacher or learning content. For example, the teacher can also decide whether other students can/may make comments or not. In this respect, the teacher can also give the floor to specific students or to the entire class via the digital twin of the physical books, and the digital twin enables a virtual classroom, but without the need for a presence such as in a digital online meeting.

• Schüler können über ein systemseitig bereitgestelltes Computerprogramm(produkt) und/oder oder ein Webinterface (Internetbrowser) Zugang zum jeweiligen Content erhalten (wahlweise ist dieses Computerprogramm(produkt) spezifisch für Schüler ausgestaltet und im Vergleich zum Nutzungsumfang für Lehrer eingeschränkt). Ein Webinterface kann insbesondere für eine/die Systemvariante bzw. Implementierungsart, bei welcher ein/der Lehrer Content lediglich mit den Schülern teilen bzw. gemeinsam nutzen darf, aber nicht mit den Schülern kommunizieren können soll, die Handhabung weiter vereinfachen und die Nutzung von z.B. einer spezifischen Applikation (App) nicht erforderlich machen. Für den Fall, dass eine Nutzung mittels eines Computerprogramm(produkt)es gewünscht wird, kann wahlweise auch für die Schüler eine Anmeldemaske vorgesehen sein, insbesondere um einem jeweiligen Schüler freistellen zu können, ob eine personenbezogene Nutzung oder Kommunikation gewünscht/freigegeben wird.

2/ Access to the content stored via the second QR code (or a correspondingly correlated range of functions, e.g. a communication platform) by students:

• Students can access the respective content via a computer program (product) provided by the system and/or a web interface (Internet browser) (this computer program (product) is optionally designed specifically for students and is limited compared to the scope of use for teachers). A web interface can further simplify handling and the use of a specific application (app) not required. In the event that use by means of a computer program (product) is desired, a login mask can also be provided for the students, in particular to be able to let a respective student decide whether personal use or communication is desired/released.

Pupils can also exchange ideas with each other on a specific topic if necessary, without the need for a teacher to be involved. For example, the students (or the students belonging to a particular group of people, e.g. also a subset of students in a class, e.g. for project work) scan a specific QR code on a specific page of the respective print medium, look at the content correlated with it (e.g. videos or images of a specific lesson sequence or a company tour or the like), in particular content that the teacher has uploaded/stored for this purpose, carry out an exercise together and/or communicate via a chat or forum function within the group (closed virtual room). For example, a mark is placed on a video or a photo of the panel painting and a question is stored for it. The classmates and/or the teacher then have the opportunity to respond and help. In this way, the students can exchange information with each other and also work together outside of school hours, in particular without having to disclose or exchange personal data (i.e. no telephone numbers or entire telephone books).

In this respect, the students can also use the system completely anonymously via a/the computer program (product) and optionally also communicate with one another ("chat"); for example a first student/user is referred to by the system as "User-A" or "Student-1" and a second student/user as "User-B" or "Student-2". The teacher can also be denied access to personal data.

Last but not least, it has been shown that the system according to the invention can also facilitate teaching or instruction with, for example, students who are restricted to staying at home privately due to the pandemic or with students/people who are chronically ill. Last but not least, it is made easier for the teaching staff to find out the current level of knowledge of the students and otherwise also other types of student feedback. The system according to the invention also offers considerable time savings in knowledge management, because content provided by the teacher can be queried directly via the respective book of a respective student; it is also possible to react quickly and easily to accidents, hospital stays, stays abroad or other obstacles that make face-to-face teaching difficult. Last but not least, the inventive linking/correlation of the teaching content based on a physical classic book, in which each student can also work by hand, enables a strong personal identification and an interested, topic-related attitude of the students, and last but not least a higher acceptance of educational institutions as such , so that better learning success/progress can be expected. The possibility that a teacher can release individual second QR codes for predefinable individual students in order to fill them with content that is interesting from the student's point of view, stimulates the discussion and dealing with the teaching content on the part of the other students. Last but not least, the system according to the invention also promotes a kind of educational competition and knowledge ambition.

According to one exemplary embodiment, a/the specific end device or the content accessed by the user via it is scanned both by scanning the first QR code/code or by manually entering a master code, preferably configured as a combination of numbers and digits, and by scanning the at least one linked second QR codes for access to these linked second QR codes or to the content stored/stored via them on the server (twice scanning or code verification required).

According to one exemplary embodiment, the teaching/teaching system has at least a first type of book with at least one of the first (QR) codes, which is/are linked to a/the first access authorization; wherein the teaching/teaching system has a plurality of books of a second type with second QR codes which are linked to a/the second access authorization, the second QR codes of each book of the second type each belonging to a subgroup of second QR codes , wherein the first QR code/code has a unique identification feature and is linked to a respective second QR code, the first access authorization defined by the first (QR) code being stronger than the second access authorization, the first access authorization being preferred includes all access rights in relation to all second QR codes or all books of the second type, and wherein the second access authorization preferably only includes access rights in relation to QR codes of the corresponding subgroup and is also preferably limited to reading, writing, uploading.

According to one embodiment, the system provides a time-parameter-dependent access authorization for each analog print medium or user, based on which access to the respective second QR code or to the content correlated with it is only possible for a predefined/predefinable period (e.g. a few minutes or hours). Entry/reading of the first (QR) code is released (denial of access authorization if the time parameter is not met, in particular for the purpose of security). This also provides an additional safety barrier.

According to one exemplary embodiment, entry/access authorizations can be assigned for at least one or two of the three following types of use, in particular depending on a user-specific release of the type of use: anonymous type of use; semi-anonymous type of use; non-anonymous personal use type. This also enables a different way of viewing and commenting on and editing content, in particular in the sense of teaching for an entire school class or person-specific instruction.

According to one exemplary embodiment, the respective entry/access authorizations can be assigned via at least one time parameter in at least one predefinable time corridor. The time parameter can be predefined by the system, in particular group-specifically, or specified by the teacher in a specific context.

According to one embodiment, only the first QR code/code is an individual code, with the second QR codes belonging to a predefined group of print media on the respective page of the print media are identical. Or the respective first QR code/code and the second QR code are all individual codes that are assigned/assignable to specific print media. Last but not least, this possibility of variation, which can be predefined by the system, also facilitates an application-specific implementation of a possibly desired level of anonymization or a possibly desired person-specific type of use.

According to one embodiment, the teaching/teaching system provides an assignment function via the graphical user interface, by means of which an assignment of individual analogue (print) media to individual persons (groups) can be implemented, in particular by a person registered in the system selecting the individual (print) Assigns media according to actual distribution (ownership) via the corresponding QR codes. Last but not least, an assignment made by a teacher or another hierarchically superior person also provides the flexibility of the system described here with regard to variable group composition.

According to one embodiment, the teaching/teaching system is set up, the individual access/access rights based on a/the link of the (print) media specified by the first and second QR codes and a/the by a/the via the personal /user-specific registration process to define the scope of access/access for the individual users in or via a digital twin of the actual distribution/assignment of the (print) media to the users and to manage them.

According to one embodiment, the teaching/teaching system is set up to map a digital twin of a large number of print media used in at least one predefinable group of people and the first and second QR codes stored therein in a print media-specific manner and to provide content correlated with the QR codes for a specific group or user. The number of groups and corresponding digital twins can be scaled individually for each application, e.g. for a school with e.g. nine grades with five classes each and an average of 25 students per class (school class = group).

The aforementioned object is also achieved by implementing a computer program product for implementing a method for providing content (content) that is/can be stored on at least one server with individual access authorization or a corresponding link or individualized access/access to the content, with at least one analogous (Print) medium and at least one server and at least one in particular mobile terminal with an optical detection device interact with one another in a teaching/teaching system, in particular in a teaching/teaching system according to one of the preceding claims, wherein the at least one analog (print) medium is equipped with QR codes and is/is correlated with at least one QR code-based access authorization to content stored/capable of being stored via the QR codes; wherein the individual analogue (print) media have at least one first QR code/code and at least one second QR code linked thereto, wherein the first QR code/code and the at least one second QR code are each in/on the same ( Print) medium are provided, wherein the individual second QR codes are also predefined in the system in such a way linked to at least one specific of the analog (print) media (in particular by corresponding mapping in a digital twin of the actual (print) media Distribution to the individual users), in particular also with a specific page of the respective analogue (print) medium, that a link/correlation of a/the respective end device via the first QR code/code to the second QR code and the QR codes stored above it Content takes place when the first QR code/code is scanned using the corresponding end device or entered manually and when at least one of the linked second QR codes is in the middle ls of the corresponding end device is scanned, with a graphical user interface being provided on the system side, by means of which a respective user is/is prompted on the system side at least when scanning/entering the first QR code/code and/or the second QR code for the first time, either a person -/user-specific registration process using the corresponding terminal device based on person-specific registration data or to initiate non-person-specific system use using the corresponding terminal device, whereby depending on this person(non)specific registration, the system issues a/the access/access authorization specifically for the at least one terminal device or is assigned individually for the corresponding user or the registered person, in particular at least one first entry/access authorization for a person-specific registered user and at least one second entry/access authorization for a person Unspecific users, in particular also when/through the use of a teaching/teaching system previously described above. This results in the advantages mentioned above, in particular with regard to ver improved interaction between teachers and students and more varied teaching of teaching content.

The teaching/teaching system has, for example, at least one first QR code/code with at least one first access authorization and at least one second QR code linked thereto; wherein a/the access authorization is assigned individually by the system specifically for a/the at least one terminal device, in that the first access authorization of a/the first QR code/codes, which is associated with at least one predefined second QR code or with one of several predefined groups of second QR -Code is linked / is linked to which at least one specific terminal is assigned, whereby when / by both scanning the first (QR) code or by manually entering a master code preferably configured as a number/digit combination and by scanning the at least a second QR code linked thereto by means of a/the specific at least one end device, access to this linked second QR code or to the content (content) stored/stored via it on the server is released on the system side for this specific mobile end device, in particular access for reading/playing the content of the respective second QR code and optionally also ei n Access to sample the respective second QR code.

In particular, the method is carried out based on at least one of the features described above. The corresponding disclosure described in connection with the system also relates analogously to a/the method described here.

A respective group of people is preferably only created and/or changed by a person registered in the system; For this purpose, the registered person can also receive the registration data from an institution external to the system, e.g. from the Ministry of Schools/Education or a correspondingly authorized regional representative thereof. Alternatively, the print media and QR codes can also be created in coordination with the relevant school/education ministry, e.g. with regard to the maximum number of people allowed in school classes. In this way, the individual print media can be made available in a material- and cost-efficient manner. An individualization of the actual group distribution and a corresponding mapping by the corresponding digital twin can then be carried out individually by the authorized/registered teacher.

The aforementioned object is also achieved by a computer program product comprising instructions which, when the computer program product is executed on a computer, cause the latter to execute a previously described method on the computer, in particular a computer program product set up to assign a (respective) access authorization specifically for at least one in particular a mobile device (in particular for a limited period of time), in that a/the first access authorization of a (respective) first (QR) code is assigned to the at least one specific device, whereby when/by scanning the first (QR) code and the respective second QR code by means of this specific at least one terminal device, access to these linked second QR codes or to the content (content) stored/stored via it on the server is released for this specific terminal device, with the computer program product preferably also having a user interface with functions selection regarding at least two of the following functions: edit, store link, upload data, enable exercise, enable chat. This also enables efficient interaction based on the previously mentioned benefits.

The aforementioned object is also achieved by using a teaching/teaching system for providing content (content) that is/can be stored on at least one server with individual access authorization using QR codes, with at least one group of analog print media, in particular textbooks, and at least one server and a plurality of mobile end devices interact with one another in the teaching/teaching system, with at least one first QR code/code being provided for each group of analogue print media in the respective print medium, with the analogue print media being equipped with individual second QR codes and each with at least one QR -Code-based access authorization to content stored/stored via the QR codes are/are correlated, in particular of a teaching/teaching system described above, in particular based on at least one of the analog (print) media used by means of the QR -Codes mapping and gr Group-specific digital twin, in particular when/for providing content correlated with the second QR code in a partially anonymous or non-anonymous person-specific manner, in particular in a method previously described above, in particular for the administration and assignment of digital content to the individual print media or Users or groups of users based on the scanning of first and second QR codes, in particular one previously described above. As a result, the aforementioned advantages can be realized, in particular with regard to an optional person/user-specific type of use.

The aforementioned object is also achieved by using a computer program product in a teaching/teaching system for providing content (content) that is/can be stored on at least one server with individual access authorization by means of QR codes, with at least one group of analogue print media, in particular textbooks, and at least one server and a plurality of mobile end devices interact with one another in the teaching/teaching system, with an individual first QR code/code being provided for each group of analogue print media and individually in the respective print medium, with the analogue print media being equipped with second QR codes and each are/are correlated with at least one QR code-based access authorization to content (content) that is/can be stored via the QR codes, in particular in a teaching/teaching system described above, in particular when/for providing with the second QR Codes correlated In hold in an anonymous person-unspecific way, in particular based on at least one group-specific created digital twin (in particular created/created/stored on the server as part of a person-specific registration of a teacher or other hierarchical superordinate/priority subject via a graphical user interface in the system), in particular in a method previously described above, in particular for the administration and assignment of digital content to individual print media or users or user groups based on the scanning of QR codes. As a result, the advantages mentioned above can be realized, in particular also with regard to the provision of the print media.

Summary: When using both analogue and digital content, it is important to provide access rights for individuals (groups) in a secure and efficient manner. A teaching/teaching system with analogue (print) media and a server is provided, the system being used by a number of mobile end devices, with the (print) media each being equipped with QR codes and with via the QR -Codes are linked to content that can be stored, the teaching/teaching system providing at least one first QR code with at least one first access authorization and second QR codes linked thereto. According to the invention, it is provided that a/the access authorization can be assigned individually by the system specifically for at least one mobile terminal device, in particular for a limited period of time, by sending the access authorization of a/the first QR code to the terminal device by scanning the first QR stored in the corresponding (print) medium code and the respective second QR code is assigned. As a result, the access authorization can be made dependent on possession of the first and second QR code and can optionally also be restricted to specific, predefinable mobile end devices on the system side.

DETAILED DESCRIPTION OF THE FIGURES

The invention will first be explained with general reference to all reference numerals and figures. Special features or individual aspects or aspects of the present invention that are clearly visible/representable in the respective figure are discussed individually in connection with the respective figure.

A teaching/teaching system 10 and a method are provided, in which a plurality of analog (print) media P, P1, P2, ..., P21 and a server 11 and a plurality of mobile terminals 20 are provided, with the respective analog Medium (especially a book) is equipped with at least one QR code and is correlated with content that can be stored via the QR code. On the one hand, a first (QR) code 1 is provided, in particular in connection with a master code 1.1, and this first code 1 is linked to at least one second QR code 2, via which the content can be stored or retrieved. the (QR) codes are managed via the server 11 and at least one data memory 13 and linked to one another according to predefined/predefinable access rights (link 15). The mobile terminals 20 can access this content or a further range of functions via wireless communication interfaces 17 based on correlations 19 of second QR codes 2 with content stored in the data memory 13 . The terminals advantageously have at least one optical detection unit 21 (in particular a camera or scanner). A computer program product 40 (in particular with an app and/or with a QR code scanner application) facilitates user interaction via a graphical user interface 23 and an input mask/surface 25, the latter in particular also allowing a non-camera-bound entry of a master code facilitated. In this case, for example, the following steps take place: step of detecting a/the second QR code using a first terminal device, in particular for the purpose of uploading content; step of detecting the first (QR) code by means of a first terminal; Step of capturing a/the second QR code using a second end device, in particular for the purpose of reading out content; Step of capturing the first (QR) code using a second end device. These steps are preferably only carried out when an actual group distribution and book assignment has also been mapped digitally in the system, which can be done in particular by a user with administrator rights or at least with extended rights, particularly user-friendly and ergonomically based on scanning at least one QR Codes from a respective book. The following examples relate to individual applications/implementations of the present invention, for example for individual schools, classes or study groups, in particular with an individually definable degree of anonymization. A predefined/predefinable institution, in particular a school, is denoted by the reference AC, and individual school classes in particular by the references K10A, K10B (class 10A, class 10B), and the reference PK refers to a predefined/predefinable subject area (e.g. politics). or the corresponding page area or section in the relevant book.

In the figures, information or messages that are developed or entered while using the system and are output to the individual users by the system (in particular visually via the respective user interface) are identified by quotation marks "...".

In the 1 (comprising the figures/ until shows an example of a process where a teacher provides content for the books of one of his classes. To do this, the teacher scans (process according to 1A , 1B ) in the registered state, the corresponding (second) QR code on the page of the book to be recorded (here: book P21, school AC, class 10A, page 5, cf. 1A ), or the teacher selects the correct class and subject as well as the desired page (here page 5) and the QR code to be recorded via the user interface (process according to 1C ; here, for example, politics as a school subject/topic, class 10A, page 5). It is digitally stored in the system which type of book or which individual book has a QR code on the respective page and how or by whom this can be recorded/correlated with content. The scope of the access rights can be individualized by the teacher for a particular class/group or for a specific person.

According to 1D the system tells the teacher via the user interface what can be done with the selected QR code, e.g. what content can/may be uploaded/correlated. In the present example, the teacher is offered four options: edit, store link, upload data, enable exercise, enable chat; whereby the respective option can be used/enabled either for all users or only for individually definable users (cf. the two lower control surfaces of the user interface according to 1D ). In the present example, the teacher decides to link to a current video (e.g. on a current political situation) (second control panel from the top); In this example, the teacher also decides to activate this link or this QR code access for all of his or her school books or students registered in the corresponding class (lower control surface on the left).

Since the books P1 to P10 are assigned to this one specific class (here: class 10A in school AC), the system now automatically (in particular implemented by the digital twin already shown) in all relevant/affected/included policy books in the present context on the corresponding Page (here page 5) the released link or content provided. The teacher's book P21 (cf. 1F ) is already linked in the system and is therefore linked/correlated with this activation.

1G shows the specific student book P8 of class 10A, and 1H shows a possible use of the content accessible via the QR code printed there by or by one of the students (in particular playing a video). This can optionally be implemented using a classic QR code scanner (after scanning the link to the content/video is provided and can be played via the web interface) or the student(s) use a computer program (product) set up for this purpose with an integrated QR code scanner (or integrated access function to the camera of a device).

At the relevant point in time, a “scan” request to scan the corresponding QR code can be transmitted to the respective user via the respective user interface, in particular purely visually or by means of an acoustic (audio) message. Last but not least, this facilitates fast and intuitive operation/use.

In the 2 (comprising the figures/ until a first variant for a distribution and assignment of the individual books in the corresponding digital twin is shown, with each QR code in the individual books being individual/different.

Example: A specific school gets a total of 44 new politics books for two classes of grade 10 (class 10A and class 10B) with 20 students each. The teacher of class 10A now scans the first QR code/code (main QR code or master code) or any individual second QR code of a respective book in the registered state via a/the computer program (product) via the user interface , in particular by means of (s)a teacher app in which the teacher is logged in or personally registered (no processing without registration of the teacher). Previously, the teacher has selected his class and subject in the system (or their counterpart in the corresponding digital twin) and has selected or executed the "Add new book" step via the graphical user interface. Now the teacher scans a (second) QR code of one of the new books to be created in the digital twin and, based on these individually assigned QR codes, assigns this (uniquely identifiable) book to his class. The teacher teaches the system the composition of his class or creates the corresponding digital twin accordingly (or provides the book-specific QR codes as information that the system needs to create the digital twin accordingly). Depending on whether anonymous or partially anonymous or non-anonymous use is desired/required, either the teacher can now also assign a particular book to a specific student or the student concerned can do this, especially when scanning the book for the first time, especially after the student has selected their class and subject.

Now all existing books of class 10A (K10A) in the subject politics (PK) are scanned by the politics teacher (i.e. at least one individual QR code from the respective book) and thus only assigned to the desired class 10A, and then the books are sent to the students issued. Use is now regulated in particular by the respective book owner, especially in the weakest security level; optionally further security levels can be provided/implemented. For class 10B (K10B) the teacher does the same. In this way it can be ensured that person (group)-related access authorization can be managed via the corresponding QR codes, ie only the students in the respective class can see or optionally edit the content released by the teacher for certain books .
Should it become necessary to order more books (eg if the class is expanded with more students), the teacher can add these books to the appropriate class in the same way as described above.

This concerns the 2D or the left of the in 2G terminals shown the process of assigning a class, and 2E or the right of the in 2G end devices shown relates to the process of assigning a student. Information relating to the school, the class, the subject area and the currently affected page of the print medium can be displayed via the user interface on the display of the terminal device, in particular immediately in response to scanning a/the corresponding QR code.

At the in 2 In the example shown, each (second) QR code is an individual code that contains all relevant data/links for the exact assignment of the book to a class and optionally also to a specific student. Optionally, the respective second QR code contains only partial information, and the remaining information can/is supplemented by the first QR code/code (main QR code or master code). 2 illustrates how 20 books for the school subject politics can be assigned to classes 10A and 10B. After scanning (cf. 2D ) the teacher can assign the respective book to his class ( 2D ), and optionally assign a person-specific student directly ( 2E ). All other QR codes available in the respective book are linked to one another, eg managed by the system under a specific serial number, and automatically assigned to the class. Through the field " 2F ' illustrates what information the individual QR code on each page as well as the main QR code can contain, in particular at least one feature relating to a specialist area (e.g. politics), a grade, a year, a book number, in particular also a/the serial number, and/or a page number (whereby the serial number is primarily used to identify a book or its edition or the intended school class or the subject area concerned, and in particular is provided by the institution or the publisher outside of the system /can be; in this respect, the serial number can facilitate assignment to the school class and tracing; the serial number can be managed by an institution, e.g. a ministry, or by the creator of the QR code). From this information, each QR code can be assigned a specific identifier (identification feature) and stored in the system. Thus (on the system side) it can be understood based solely on the scanning process how the 20 politics books that were delivered to school AC were assigned to classes 10A and 10B. The entire procedure can be carried out efficiently, especially in a few minutes, even with a comparatively large number of books and large classes/groups of people.

In the 3 (comprising the figures/ until a second variant for a distribution and assignment of the individual books in the corresponding digital twin is shown, whereby only the first QR code/code (main QR code or master code) is individual (all other second QR codes in the respective book are the same/identical). Only with the first QR code/code is an assignment to the class or, if desired, to specific students. In this variant, for example, there are also production-specific advantages, in particular in connection with the provision of the print media (comparatively simple printing process). Example: 100,000 new history books for grades 9 and 10 are ordered for a city. These 100,000 books, apart from the individual first QR code/code, have the same second QR codes on all pages. In this respect, for example, QR code 1 is the same on page 5 in each of the 100,000 books, and QR code 2 is the same on page 10 in each of the 100,000 books. In this way, the different pages in the book can still be distinguished from one another, and topic-specific correlation is possible. The assignment for a first school in the city (A1) and class 9B is then ensured solely by the first QR code/code.

This concerns the 3B or. 3F the process of assigning a class, and 3C or. 3G affects the process of assigning a student. Information relating to the school, the class, the subject area and the currently affected page of the print medium can be displayed via the user interface on the display of the terminal device, in particular immediately in response to scanning a/the corresponding QR code.

The other possible uses (features) described above, e.g. the specific assignment to a student, can take place in the manner described above. The student scans the first QR code of his book and the system knows/stores that it is class 9B at school A1. In this respect, the student can use the book and the QR code functions as described above with restrictions or with all features depending on the desired degree of anonymization.

In contrast to the example above, no assignment to the class or student can be made if, for example, only the second QR code on page 5 is read/scanned. Rather, the first QR code/code must also be scanned or entered at the same time (as an alternative to a QR code, a master code made up of numbers and/or letters can also be provided/used as the first code, in particular to To be able to verify the code without scanning, e.g. if a QR code scanner is defective). When assigning the class, the first QR code must be scanned by the teacher; the same applies to the person-specific assignment for students (if desired).

This second variant is particularly advantageous with regard to the creation of the print media/books, since the QR codes are the same apart from the main QR code (or first QR code/code) on the same pages of the individual books. However, care must be taken to ensure that the first QR code/code is always available and readable, because an assignment cannot be made using the second QR code alone.

Optionally, it can be set user-specifically whether a/the computer program (product) or an Internet browser (when using a web interface) can save the first QR code/code (in particular by storing corresponding cookies); then it is also possible with variant 2 to use or access the stored content without scanning the first QR code again (as well as an assignment).

If reference is made in the figures to scanned QR codes (i.e. to the image of the actual QR code on the display of the respective end device), this is indicated by brackets according to (1) or (2).

In the 4 the functioning of the system based on the two different QR code types (first QR code/code and second QR codes) is explained in general. This concept can essentially be transferred to the respective application independently of the number and desired distribution/allocation of print media.

In particular, in 4 illustrates how several end devices 20 (e.g. by means of an app or by means of a QR code scanner) independently of one another a first (QR) code 1 or the associated master code 1.1 and at least one (by the system or in particular by means of the print media is already predefined) linked to the first code, the second QR code 2 in order to gain access to the content linked via the second QR code and stored in the data memory 13 of the server 11 (e.g. video data). A message is preferably given to the user on the respective end device via a graphical user interface 23 (e.g. depending on the type or time or degree of repetition of the recording and depending on the desired access authorization: "To upload content for the first time, please scan or enter the first code"; or "To view content for the next 12 hours, please scan or enter the first code"). If manual input of a/the master code 1.1 is desired or required, an input mask/interface 25 provided for this purpose on the end device can also be used for this purpose.

For example, in order to be able to load content onto the server for a specific page (or for a specific subject area) of a book used by a student, the user is asked to enter the first QR code in addition to the (second) QR code to be recorded scan (or enter a so-called master code manually; the master code is a combination of numbers or digits that is arranged under the main QR code and can be read by the user). This first QR code is linked/correlated to the other second QR codes of the QR code system used or the associated database or the analog media involved and also serves as a kind of two-way authentication. In addition, the user (especially a teacher) is optionally asked whether a personal password should be added, in the sense of an additional security barrier with regard to access to the content and/or to unlock an extended (teacher) functionality, in particular for the purpose of editing a /the digital twin of a book distribution/allocation to a specific school class. This password can optionally replace or supplement the query for the first QR code in the further course of use, but there can also be a double (if redundant) query for access authorization (extended two-way authentication). This design also makes it possible to decide individually about a desired security level, with or without entering personal data, e.g. with regard to data protection regulations that differ locally or temporally or that are specific to age groups.

In order to retrieve content stored via the second QR code, the system can also recognize (in particular using cookies) whether the person in question (or the user or their end device, smartphone, PC, tablet) already has access authorization and is asking this, if necessary, again via the first code or master code (in particular in relation to a point in time, time-dependent); If there is no access authorization or the level (strength) of an access authorization required for the desired action (only reading out or new samples) is available (or the time has already expired), the system will start again after the first code (main/master code ) and/or asked for a user-specific password. This does not necessarily take place via an APP provided for this purpose, but can also take place via a WEB/Internet interface (in particular a website) to which the second QR code (link) leads. After successful authentication, the respective person (or their system/smartphone/PC/tablet) is activated, whereby the duration of the activation is preferably set to a specific time (e.g. after a few minutes or from 6-12 hours afterwards, the user is asked again first QR code and/or one/of the password; for the linked second QR code it is not mandatory to re-enter the first code or the master code). This also prevents other people/users from gaining unauthorized access to the content stored behind the QR code. A/the personal user-specific password can optionally be changed by the respective user at any time. It is also possible to carry out a random query from a QR code stored in the respective analogue print medium (especially a book). The authorization query can also be set in such a way that the system asks a user for a specific QR code on a specific page of a book and the user has to specifically scan this QR code in order to unlock the content (predefined /predefinable correlation between first code and single specific second QR code).
