        <p>Augmented reality (AR) in printed books brings new possibilities for enriching the reader's experience as well as making the product more attractive to customers. In order to investigate the functionality of augmented reality elements in books and the feasibility of their use this article analyses the Ukrainian AR book market; identifies the Ukrainian publishers that use the technology, describes the promotional activities they do for such books; and assesses the possibilities of readers' access to AR elements in the analysed books. Given the small number of books using AR available on Ukrainian market and the lack of a standard in its description the search for such books and publishers was carried out manually. In this research we used both classical methods for the analysis of the book market and publishing products, and a system of methods aimed at the analysis of data atypical for the book market, such as the analysis of technological aspects of software or augmented reality. The first group of publishers consists of specialised publishing houses, for which book production with AR is the main type of activity. The second group includes publishers that have some augmented reality products in the assortment. Within the third group of publishers, books with augmented reality are exclusive; AR technologies are not their area of interest and development. The most common way to present information about AR in books is to indicate it on the cover; some books have it mentioned on the websites of publishing houses and bookstores, and others use bibliographic details or front and back information for this purpose. There are mainly children's fiction and educational AR books in the analysed collection, which use different ways of entering augmented reality, such as a QR code, an application or an Instagram effect triggered by an image. These books incorporate 2D and 3D animation, music, sounds, and voiceover; some include a fully recorded audiobook. Experimental test use of available applications for Android and iOS devices showed some issues in their work due to inconsistency of support, as well as promising possibilities for development. Recommendations on implementing AR elements into publishing products were formulated and possible ways of further research were outlined.</p>

      <title>1. Introduction</title>
      <p>The definition of augmented reality (AR) refers to a type of virtual environment or virtual reality.
Virtual reality technologies completely immerse the user in a synthetic environment, where it is
impossible to see the real world around you until you plunge into virtual reality completely. Unlike
this technology, augmented reality allows the user to see the real world, while virtual objects are
superimposed on or integrated into the real world. It follows that this technology complements reality
and does not completely replace it. In fact, it seems to the user that virtual and real objects coexist in
the same space.</p>
      <p>
        Researcher Ronald Azuma, in his article A Survey of Augmented Reality, describes the properties
of augmented reality that are widely used today to define the technology. AR technology combines
real and virtual objects that are reproduced in real time. It is interactive and also registers or places
virtual objects in a real environment [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ].
      </p>
      <p>In recent years, augmented reality technology has been introduced into many areas, for example in
AR shopping, for travel and learning needs. Of course, the publishing sphere is not an exception. The
essence of AR use in books is that when a smartphone or a tablet camera is pointed at the trigger,
interactive content opens to users. Readers see virtual objects with animation or video, which they can
interact with and control in a story space. Augmented reality is definitely the technology of the future.
That is why it is significant to evaluate how it is being used in the contemporary Ukrainian book
industry.</p>
      <p>Given that today’s recipient is primarily visually oriented, finding new ways to engage them in
reading is a challenge for modern publishers. The need to intensify interest in books and promotion of
reading is a general global trend, to which for instance the Ukrainian Book Institute responds with its
activities and projects.</p>
      <p>That is why the main goal of this study is to investigate the functionality of augmented reality
elements in books and the feasibility of their use; to look at them through the eyes of an average
reader (user) and evaluate how readily they are available. This will make it possible to assess the
challenges faced by modern publishers and give them recommendations on implementing AR
elements into their publishing products.</p>

      <p>
        Most available sources on the topic analyse concepts, typology [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ] or even philosophy of
augmented reality [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]. A significant number of works describe its educational and learning purposes
[
        <xref ref-type="bibr" rid="ref5">5</xref>
        ], research reader’s motivation, attitudes [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ], concentrate on discovering new levels of reader’s
experience [7] or making physical printed books more functional [8]. The group of researchers from
the University of Surrey in their recent press release [9] announced new unexpected ways of possible
book transformation with the means of AR.
      </p>
      <p>During last ten years Ukrainian researchers were also turning their eye to augmented reality in
books, first hesitant, but now more widely. One of the most prominent monograph in the field, Digital
transformations of the publishing industry by Maryna Zhenchenko, briefly mentions a tendency of
“gradual transition from the production of individual products to the service-oriented design of
customized cross-media publishing projects and services using augmented reality technologies, web
analytics data, Internet of things technologies, network communication tools, artificial intelligence
technologies for the promotion and sale of publications” [10].</p>
      <p>Recently the issue of using augmented reality in books was considered in articles by Svitlana
Vodolazka, in doctoral dissertation [11] and series of articles by Anastasia Bessarab, in articles by
Yuliia Shchehelska [12] and by Liubov Panchenko et al [13], [14].</p>
    </sec>

      <title>3. Proposed methodology</title>
      <p>In order to reach the main goal of this research we need to determine which Ukrainian publishers
work on the AR market and how they carry out the promotion of such books; to analyse available
printed books that implement AR technologies; and to evaluate the types of reading experience they
offer. Since we focus on the promotional features of the books, we do not consider textbooks that use
augmented reality but are not commercial production. We also do not take into account AR e-books
since they do not have a physical printed component.</p>
      <p>Taking into account the fact that this technology is a novelty, especially for publishers in Ukraine,
the number of Ukrainian books using AR is, statistically speaking, very small. In addition, it is
difficult to find information about AR elements in the publication in its description. That is why the
search for such books was carried out manually, and this study presents, with very few exceptions, all
Ukrainian AR books that are currently available on the book market.</p>
      <p>The complexity of the study of the Ukrainian market of books with AR and its development
prospects determine the complexity of the research methods we use. The author of the monograph
dedicated to the digital transformations of the publishing market [10] outlined the absence of reliable
methods of measuring variables as one of the problems of conducting the research upon complex
dynamic systems (in particular digital innovations in the publishing industry). This leads to the
involvement of survey data, analysis of indirect data and other methods for obtaining objective
information.</p>
      <p>Therefore, in this research we had to use both classical methods for the analysis of the book
market, basic methods for the analysis of publishing products, and a system of methods aimed at the
analysis of data atypical for the book market, such as the analysis of technological aspects of software
or the typology of augmented reality.</p>
      <p>The data collection and comparative analysis methods were used to explore the various examples
of available AR books and publishers present on the Ukrainian book market. Using the method of
bibliographic information search, systematization and typology, books with augmented reality
available in Ukrainian market were identified. The method of commodity analysis of the book product
was applied to the way the data about augmented reality in shown in the commodity information
about the book and was used for the typology of publications. Systematic and socio-communicative
methods were used to analyse the activities of publishing houses and the content of publications,
publishers’ websites etc. The method of interviewing representatives of each of the categories
involved in the process from the production of the edition to the consumer (publishers, designers,
bookstore sellers, library workers, buyers, readers) was also applied. The obtained results of empirical
information collection were studied and analysed also using general scientific methods of analysis and
synthesis, comparison, classification and typology, observation and experiments, generalization and
analogy. In order to understand the basic functional features of AR apps and what they bring to the
reader’s experience, we conducted an experimental test use of the available applications for Android
and iOS devices.</p>

      <title>4.1. Review of publishers specialising in books with augmented reality</title>
      <p>Almost a decade has passed between the launch of books with augmented reality in Europe in the
early 2000s and their arrival in Ukraine — the active use of AR technologies in Ukrainian book
publishing dates back to 2017, when the first publishers and editions of children’s books with
augmented reality appeared. Over the past 5 years, their number has been constantly growing, and the
assortment has expanded to include educational literature and art books [15], [16]. However, this
segment of the market is still developing rather slowly, as evidenced by the assortment of bookstores
and the observations of researchers. Svitlana Vodolazska, when analysing the factors of the slow
entrance of AR technologies into the publishing market in Ukraine, recorded the products of 11
publishing houses on the online bookstore market in 2021, with each publishing house having less
than 10 titles [17].</p>
      <p>Given this situation, finding information about books with AR and its publishers is quite difficult
and had to be conducted manually. It is not very clear in which part of the book this information
should be indicated. Existing Ukrainian standards of bibliographic description of books use somewhat
outdated approaches and also do not take into account new technological possibilities. The digital data
of the Book Chamber of Ukraine named after Ivan Fedorov (a leading Ukrainian organization that
contains mandatory copies of all book titles published in Ukraine) do not include augmented reality as
one of the book characteristics. Searching by keywords in the catalogues at The Vernadsky National
Library of Ukraine (one of the most prominent Ukrainian scientific libraries) gives only one search
result with AR.</p>
      <p>Upon analysing the Ukrainian publishing market through the prism of the specialisation of
publishing houses in AR books, which are also compared in Table 1, we have singled out three groups
of publishing structures.</p>
      <p>The first group consists of specialised publishing houses, for which the production of books with
AR is the main type of activity; publications with augmented reality dominate in their assortment.
Among them is the publishing house Art Nation Publishing (an international group of Art Nation
companies), founded in 2017 with the aim of publishing books with augmented reality for family
leisure. The very next year, in 2018, the publishers achieved significant success, taking first place in
The Largest Circulation of One Title rating (640 thousand copies of Alice Through the Looking-Glass
and 1 million 241 thousand total copies of both books about Alice’s adventures). This publishing
house develops augmented reality not only for its own publishing products but also offers AR
development services to other publishers-customers. On the Ukrainian market, within the framework
of the WowBox project, books were also published by other publishing houses under a license (Vivat,
Ranok).</p>
      <p>In 2018, the FastAR Kids trademark by the international FastAR company appeared (the
publishing house is registered as Fastbind Ukraine), which works in two directions: it develops
applications and produces children’s printed products with augmented reality (3D and professional
sound). This publisher developed “live” ABC-books for younger schoolchildren, which got into
school and children’s libraries thanks to the recommendations of the Ministry of Education and
Science of Ukraine (Live ABC-Book) and support of the Ukrainian Cultural Foundation (Kobzar’s
ABC-Book).</p>
      <p>In 2021, White Owl publishing house was set up, which is focused on experiments with augmented
reality in children’s publications. As of summer 2022, there are already 5 book titles in their
assortment and pre-sale for the next book has been announced.</p>
      <p>The widest assortment of informative encyclopaedias for children and teenagers with 4D on the
Ukrainian market was offered by the Russian publishing house Devar, which also published these
products in Ukrainian.</p>
      <p>The appearance of competing publishers specialising in AR books should be expected in the near
future, considering the development of technologies, readers’ requests, the growth of the global book
industry and the course of digitisation in Ukraine.</p>
      <p>The second group includes publishers whose products include publications with augmented
reality but they do not form the basis of the publishing program. Such publishing houses publish
books with AR together with traditional books, without placing bets on the technological support of
the book, yet the range of these publications allows booksellers and readers to expect new products
with AR in their assortment as an extension of series or similar publications. We include Ranok,
Talant, Vivat and others among such publishing houses.</p>
      <p>In the third group of publishing houses, books with augmented reality are exclusive; AR
technologies are not an area of interest and development for publishers. However, the latest trends in
the application of augmented reality and, accordingly, new opportunities also stimulated the
preparation of one or more editions with an AR effect. In particular, Old Lion Publishing House,
which is rapidly developing and monitors world book trends, was one of the first to start publishing
books with augmented reality: in 2015, a game application was developed for the book Antomimes by
the Agrafka Art Studio, later a Pumpkin Year by Kateryna Babkina with illustrations by Yulia
Pylypchasta was “revived” with AR.</p>
      <p>In 2018, Kyiv House of Books published an adaptation of Forest Song by Lesya Ukrainka, which is
part of a large animation project and contains elements of augmented reality in the book. Other
publishers are also individually diversifying their repertoire with AR publications. For example, in
2019 and 2021, the Hamazyn publishing house published Anton Khusnutdinov’s comics Nox.
Through Consciousness and Nox. Path to the Unknown. In 2020, Assa publishing house started
publishing a series of translated fantasy books The World of Supersaurs by Jay Jay Burridge, funded
by the institutional support of publishers from the Ukrainian Book Institute. With the support of the
Ukrainian Cultural Foundation, augmented reality appeared in the monograph about the destroyed
wooden churches by Publisher Oleksandr Savchuk, as well as in the popular-science guide Pocket
City and a series of postcards by Gvara Media and Skeiron.</p>
      <p>The analysis of the market of AR books publishers shows that the key players are concentrated in
Kyiv and Kharkiv; the main years of growing interest and development of AR in the book business
are 2018–2021. The development of augmented reality technologies in the book industry stimulated
the emergence of new publishing houses on the Ukrainian market.</p>
      <p>The basis of the assortment of Ukrainian AR books is children’s editions targeting children of
middle school age and teenagers, however, there are many editions for the youngest readers aged 3
years and up (the majority are editions of fairy tales, encyclopaedias and ABC-books).</p>
      <p>Publications for adult readers also use augmented reality, although this development is not as
intense as in children’s literature. Diversification of adult reading with additional technical
possibilities is also one of the trends in the Ukrainian book market. One of the factors that stimulated
the introduction of the latest technologies in the book industry was the grant opportunities provided
by the Ukrainian Cultural Foundation, created in 2017, which financed innovative publications that
have high artistic value and cultural significance and promote the latest book publishing technologies.
Augmented reality has become one of the innovative components of publications on culture and art,
as well as fiction. A demonstrative example of the apt use of augmented reality in an art publication is
the publication of Stefan Taranushenko’s book Destroyed Masterpieces of Ukrainian Wooden Sacred
Architecture, which was carried out by the publisher Oleksandr Savchuk. The publication contains 3D
models of the destroyed temples, which allow you to see the churches in detail and preserve their
images for posterity. One of the factors behind the use of augmented reality in such publications is to
attract the younger generation to the study of ancient architecture and the preservation of cultural
heritage.</p>
    </sec>
    <sec id="sec-6">
      <title>Information about augmented reality in books</title>
      <p>In publications with augmented reality, the digital factor is an important component of the book, so
informing the reader about the availability of AR technologies is an important part of product
information. While researching Ukrainian publications with augmented reality, we found that there is
no single search algorithm either on the publishers’ websites or in the networks of online bookstores.
Searching the catalogues of children’s or adult libraries for information about such publications is
almost completely fruitless.</p>
      <p>Modern technologies and methods of informing about the book on the websites of publishing
houses, bookstores and online stores make it possible to provide a detailed description of the book,
including its technical parameters: volume, format, presence of illustrations and other details, yet
information about augmented reality or additional applications for its use is absent in most of the
cases studied.</p>
      <p>Having analysed an array of publications with augmented reality, we summarised the typical
trends in presenting information about AR in publications:
1. the most common is the indication on the cover (“augmented reality”, “live book”, “bring me
to life”, “book comes to life with the app...”, “free app”, “living encyclopaedia”, WOW,
“volumetric illustrations inside”, images of Google Play and App Store logos, AR marks,
smartphone and sound icons, etc.);
2. on the websites of publishing houses and bookstores, information about AR can be added to
the title of the publication (Sleeping Beauty. A Tale with Augmented Reality, Bookstore Ye) or
displayed in a section (on the website of the Smile publishing house, the section Books with AR
Effect (Augmented reality)). On the individual websites of bookstores and other stores, such
information is provided in the section Other Characteristics (“3D effect”, “Devar Kids
application”);
3. indication in the bibliographic information and on the front and back (back side of the book
cover, endpaper, separate pages with a description of how to bring the book to life, etc.). An
example of presentation of information about augmented reality in the title, and therefore also in
the bibliographic description, is the 2nd edition of Stefan Taranushenko’s book Destroyed
Masterpieces of Ukrainian Wooden Sacred Architecture: A Book with Augmented Reality
(Publisher Oleksandr Savchuk). Some publishers of children’s books with AR indicate the
following information on the end pages (Charles Perrault. Sleeping Beauty: Augmented Reality
Book 6+. The book is part of the WowBox project). The White Owl publishing house indicates the
authors of augmented reality on the end pages.</p>
      <p>Considering the peculiarities of books with AR, it is important to note that they also require a
special approach to the promotion of the published product. Book trailers and video reviews are
effective means of promoting book products with augmented reality because they visually
demonstrate fragments of augmented reality, interactive capabilities, encourage purchase, allow you
to navigate technical features and familiarize yourself with the content. In the Ukrainian segment,
book trailers are not a common genre of advertising printed products, however, in the description of
publications with augmented reality on the websites of online stores, bookstores or publishing houses,
as well as on social networks, there are usually short clips, book trailers or links to short videos on
YouTube.</p>
      <p>Some publishing projects have a separate website or a page on the publishing house’s website or
on social networks, which complement the reading of the book, provides detailed instructions on
using augmented reality and accompanying materials. Anton Khusnutdinov’s comics Nox (Hamazyn)
and Destroyed Masterpieces of Ukrainian Wooden Sacred Architecture by Stefan Taranushenko
(Publisher Oleksandr Savchuk) have the pages on the websites and the children’s books by White Owl
are linked to the publisher’s Instagram account.

    <sec id="sec-7">
      <title>Interaction with AR books and its communicative potential</title>
      <p>The use of augmented reality undoubtedly creates new opportunities for publishers to stand out
from the competition and offer readers a new reading experience. The advantage of this technology is
the ability to use both the physical space of a printed book and the digital space of augmented reality.</p>
      <p>For example, Art Nation’s AR books use marks in the table of content to navigate within the
printed body of the book, Cinderella by White Owl even offered olfactory experience of specially
created perfumes on its pages (only 100 printed copies had this feature).</p>
      <p>This market is growing, developing and has many prospects: as mentioned in AR market research
statistics, “71% of consumers say they would shop more often if they used AR” [18]. However, it also
means more challenges for publishers and other professionals in the book industry.</p>
      <p>Many factors influence the choice of exactly how AR elements will be used in the book, primarily
financial. Developing a complicated AR application to support the book content may double or triple
an average book budget [19]. Simpler options for augmented reality, for example, just the
development of virtual models, can be more profitable and easier to maintain. Although, for instance,
in the book about destroyed wooden churches by Publisher Oleksandr Savchuk, the budget for
developing models and maintaining a web resource also exceeded the cost of publishing a book by
almost 1.5 times, as we can see from the financial report in public access [20]. This project was
financed by the Ukrainian Cultural Foundation, which is why the publisher had the opportunity to
develop AR elements at an appropriate level.</p>
      <p>In a small experimental test use, we tried to install and run the available augmented reality tools
for books. It was found that some applications are not accessible any more, some links gave an error
during an attempt to download. Some of AR tools were launched with QR codes, some books had
links to a webpage, a file for downloading an application, or to the Play Market or the Apple Store
applications.</p>
      <p>A comparative analysis of the products by different publishers and features of the functionality of
augmented reality is presented in Table 3. We analysed both a single title in the publishing house’s
assortment, and in the case of a series, we analysed the series of titles as a whole.</p>
      <p>Most publishers use specially made applications with image trackers for cameras to catch. AR in
Stefan Taranushenko’s monograph Destroyed Masterpieces of Ukrainian Wooden Sacred
Architecture (Publisher Oleksandr Savchuk) as well as in books by Smile (series A gift for a smart
person) send to publisher’s webpage with AR content. The AR in series by Smile was unsuccessful to
launch on Android and successful on iOS.</p>
      <p>For the experimental test drive, we chose one title from each publishing house (with the exception
of the Russian Devar, as we wanted to focus specifically on the Ukrainian market subjects), which
offered augmented reality in the form of an application, as the most popular form of AR content, and
tried to use them. Tables 4 and 5 provide information about these applications for Android and iOS,
respectively. In the tables we have also included characteristics that are important for understanding
the app as an element of a book product: developer and time of last update, size and (if available)
number of downloads, and overall rating.</p>

Test use of applications for iOS was conducted on iPad 9, as shown in Table 5.</p>
        <p>Several differences between the same product for Android and iOS were noticed. For example, Art
Nation Publishing offers one application WowBox AR for iOS that works with all books in the series,
but separate application for Android, which makes user struggle to find it. Gwara’s application Pocket
city AR uses one app for all products for Android (and female voice is used in audio), but several
applications and male voice for iOS.</p>
        <p>There was a slightly wider choice of Apple iOS applications which were also working better in
general. At the same time analysed applications have quite low average rating for Android
applications. Some users described it as a one-time experience for their children in their reviews. And,
of course, all of these applications take up a significant amount of memory space, which might be a
disadvantage.</p>
        <p>Experimental test use showed that AR applications obviously have a shorter lifespan than printed
books. However, the back of Vivat books optimistically states that “The expiration date is
unlimited” — with proper support that is.</p>

      <title>5. Conclusion</title>
      <p>Virtual reality in books has extraordinary prospects: the ability to enrich the narrative, invite readers
to join the story, see certain phenomena and hear certain objects that may otherwise be inaccessible.
Therefore, it is very encouraging that the Ukrainian AR book market is developing step by step.</p>
      <p>The first group of publishers available on the Ukrainian market consists of specialised publishing
houses, for which book production with AR is the main type of activity. The second group includes
publishers that have some augmented reality products in the assortment. Within the third group of
publishers, books with augmented reality are exclusive; AR technologies are not their area of interest
and development. It is obvious that the existence of the first group of publishers on the market may be
in jeopardy, as publishers who combine different types of books in their assortment have shown
themselves to be much more effective.</p>
      <p>It would be very efficient for Ukrainian publishers to look more into developing and providing
stable support for applications (specifically for Android), to be more consistent in developing and
describing AR’s capabilities to help readers find and use its tools to their full potential. Due to Statista
reports, as of February 2022, Android 11 was the leading mobile operating system in Ukraine, while
iOS had only an 8.66 % share of the market [21].</p>
      <p>Of course, the faults in functioning and infrequent application updates (and, accordingly, the low
rating) may be partly related to military actions on the territory of Ukraine. Therefore, we should hope
that publishers and developers will soon have the opportunity to return to their usual work.</p>
      <p>The most common way to present information about AR in books is to indicate it on the cover;
some books have it mentioned on the websites of publishing houses and bookstores, and others use
bibliographic details or front and back information for this purpose.</p>
      <p>Analysed books use different ways of entering augmented reality, such as a QR code, an
application or an Instagram effect triggered by an image. These books incorporate 2D and 3D
animation, music, sounds, and voiceover; some include a fully recorded audiobook, game or quiz. In
some projects, however, the AR is being used simply for the sake of the technology itself.</p>
      <p>WowBox application invites readers to be aware of the surroundings and gives a friendly reminder
for adults: “Keep in mind that this app includes exciting AR content and don’t forget to supervise your
children while using the app”. Proper supervision could be a key for all publisher’s activities as well.</p>
      <p>Augmented reality possibilities are still developing, however, there is already a noticeable need to
implement basic training in augmented reality technology into the education of illustrators, publishers
and other industry specialists. This will contribute into more efficient distribution and more
appropriate use of the AR technology.</p>
      <p>There are mainly children’s fiction and educational AR books on Ukrainian market, which is only
natural. We found only two Ukrainian AR books intended for adults: Stefan Taranushenko’s
monograph Destroyed Masterpieces of Ukrainian Wooden Sacred Architecture (Publisher Oleksandr
Savchuk) and Pocket City Lviv (Gwara Media). Both books offer an overview of architectural
monuments and demonstrate the extremely necessary and promising trend of digitizing cultural
heritage. This trend is important not only because it makes it possible to get acquainted with
inaccessible or lost places of interest. Such digitization of architectural buildings, monuments, and
museums is especially valuable in the current unstable situation during the Russo-Ukrainian war,
when the preservation of cultural heritage is under threat.</p>
      <p>The previous years of the pandemic also demonstrate the need for remote learning, and AR books
can partially help to solve this problem. In addition, AR can become an essential element of
encouragement to read, to the future desire to communicate with the book as such.</p>
      <p>The prospects of using AR in the Ukrainian book market are really exciting, given its ability to
rethink the functions of the book as a content carrier, to strengthen the content sense, the ability to
interest readers with its interactivity etc. The current market situation with AR books can be vastly
improved by:
 the expanding of the thematic assortment of AR books for both children and adults with a
greater emphasis on exploring, preserving and learning than on entertainment. In this case the
resources spent on the development of AR elements would be more efficient;
 introduction of training courses for IT and publishers to develop their skills in creating AR
books;
 in-depth information and development of skills in working with AR books for booksellers,
librarians and readers. This will help to better promote publications through the AR component;
 defining AR as one of the book characteristics in the publication description in book statistics.
This could be very important for publishers, since the AR books would be more visible on a
market. In addition, it will give insight into the effectiveness of the publisher’s actions.</p>
      <p>Appropriate directions for future research in this context would be a more in-depth analysis of
augmented reality technologies in books, detailed testing of applications, analysis of perception of such
content with the involvement of focus groups, as well as overall review of prospects for using the
capabilities of AR for various types of literature. We have only begun to discover the possibilities of
augmented reality for book market, and there are still many unexplored aspects of its use ahead of us.</p>
