Abstract. The article considers the experience of using artificial intelligence in
many different sectors and branches of the economy. Applications for artificial
intelligence are unlimited. Artificial intelligence can rationalize and take
measures providing the best chance to achieve a specific goal. The federal pro-
ject "Artificial Intelligence" was approved by the government commission on
digital development. State regulation in the field of artificial intelligence should
help accelerate economic growth and competitiveness of the national economy,
improve the well-being and quality of life of citizens, ensure national security
and law and order, and achieve Russia's leading positions in the world in the
field of artificial intelligence. A digital intelligent platform should appear soon
to support the activities of experts in the examination of the quality, effective-
ness, and safety of a medical device. The technology can be applied in many
different sectors and industries, including tourism. The most challenging aspect
of tourism is tourism for the disabled or accessible tourism. The development of
the project "Digital Profile of a Tourist" by the Big Data Association is aimed at
determining the needs of tourists with disabilities and identifying their unreal-
ized demand.
Keywords: Artificial Intelligence, Big Data, Immersive Technologies, Digital
Transformation, "Accessible Tourism".
1 Introduction
Artificial intelligence (AI) refers to the simulation of human intelligence in ma-
chines that are programmed to think like humans and simulate their actions. In the
1980s Barr and Faigenbaumdefined artificial intelligence as “an area of computer
science that develops intelligent computer systems, that is, systems that have capa-
bilities that we traditionally associate with the human mind". Later, some algorithms
and software systems began to be attributed to AI, the distinctive feature of which is
that they can solve certain problems in the way the man would do [1, 2, 3].

An important characteristic feature of artificial intelligence is its ability to ration-
alize and take measures that provide the best chance of achieving a particular goal.
Artificial intelligence includes a wide range of related technologies and processes,
including machine learning. Algorithms can automatically learn and adapt to new
data without human help. Deep learning methods enable automatic learning due to
the absorption of vast amounts of unstructured data, such as text, images, or video
[4].
This article aims to show the advantages of artificial intelligence, its applications
in accessible tourism
2 Main Content
Artificial intelligence is based on the principle that human intelligence can be defined
in such a way that a machine can simulate it and perform tasks from the simplest to
the most complex ones. The goals of artificial intelligence include imitation of human
cognitive activity. Researchers and developers in this field are taking remarkably
quick steps in simulating such activities as learning, reasoning, and perception to the
extent that they can be specifically defined. Some people believe that innovators will
soon be able to develop systems that exceed the ability of people to learn or reason
about any subject. But others remain skeptical because all cognitive activity is riddled
with the value of judgments that are subject to human experience [5, 6, 7].
Artificial intelligence can be classified into two categories: weak and strong. Weak
artificial intelligence embodies a system designed to do one particular job. Weak AI
systems include video games such as the top chess example and personal assistants
such as Amazon's Alexa and Apple's Siri. You ask the assistant a question, and it
answers the question for you. Strong artificial intelligence systems are those that per-
form tasks that are considered "human." Systems are programmed to handle situations
in which they may be needed to solve problems without human intervention. These
systems can be found in applications such as self-driving cars or hospital operating
rooms [8, 9].
From the very beginning, artificial intelligence has been the subject of special at-
tention by both scientists and the public. One common idea is that machines will be so
highly developed that people will not be able to keep up with them,
Different sectors of the economy deal with a huge amount of data available in dif-
ferent formats from disparate sources. A great amount of data, known as big data, is
becoming easily accessible and accessible due to the gradual use of technologies, such
as advanced computing capabilities, and cloud storage. Companies and governments
understand great possibilities that can be gained from the use of big data. Thus, artifi-
cial intelligence capabilities are used by various industries to collect, process, com-
municate and share useful information from data sets. One of the methods of AI,
which is increasingly used to process big data, is machine learning [10, 11].
Different machine learning data applications are formed using a complex algorithm
or source code embedded in a machine or computer. This programming code creates a
model that identifies the data and builds forecasts around the data it identifies. The
250
model uses parameters built into the algorithm to create patterns for the decision-
making process. When new or additional data are available, the algorithm automati-
cally adjusts the parameters to check for a change in the pattern, if any. However, the
model should not change [12, 13, 14].
Until 2011, big data technologies were considered to be used only for scientific
analysis and they did not have any practical output. However, the volume of data
grew exponentially and the problem of the huge amount of unstructured and hetero-
geneous information became relevant in early 2012. The surge of interest in big data
is visible in Google Trends [15, 16].
On September 1, 2020, the first national standards in the field of artificial intelli-
gence were adopted by the Federal Agency for Technical Regulation and Meteorolo-
gy: GOST P 58776-2019 "Means of monitoring behavior and forecasting of people's
intentions. Terms and definitions" and GOST P 58777-2019 "Air Transport. Airports.
Technical means of inspection. The method of determining the quality indicators of
illegal attachments detection by shadow X-ray images."
On August 27, 2020, the Presidency of the Government Digital Development
Commission approved the federal “Artificial Intelligence” project. The federal “Arti-
ficial Intelligence” project provides for the following sources and volumes of the
project financing from January 2021 to December 2024 with a total volume of 36.3
billion rubles, including 29.4 billion rubles from the federal budget (fig. 1).

The Russian concept of AI regulation is more detailed than a European one, AI regu-
lation should accelerate economic growth and foster competitiveness of the national
economy, improve the well-being and living standards, ensure national security, law
and order, and should help Russia to achieve the leading position in AI field. The
concept defines that the development of AI and robotics technologies should be based
on the core ethical norms and prioritize man’s safety and well-being, protect his "fun-
damental rights and freedoms [17, 18].
At the end of April 2021, it became known about the Ministry of Digital Develop-
ment, Communications, and Mass Media proposal to expand the introduction of arti-
ficial intelligence in Russia. In particular, the agency pointed to the need to use digital
assistants in educational and medical institutions. The Russian government has allo-
cated 1.4 billion rubles to support start-ups engaged in artificial intelligence technolo-
gies under the ‘Digital Economy” program. As part of the digital transformation of
Roszdravnadzor, a digital platform built on artificial intelligence will be created for
citizen interaction. It will help to conduct a natural dialogue in text (sites, messengers,
mobile applications) and voice service channels (open question). It will be possible to
form automatic answers to the questions of Russians asked in a free form and related
to the respect for their rights in the field of health care.
There should also appear a digital intelligent platform to support the activities of
experts in the examination of the quality, effectiveness, and safety of a medical prod-
uct. The stack of technologies used will include logical artificial intelligence, optical
text recognition, and robotic workflows. It is planned to form a database of expert
knowledge along the lines of activity with a variable structure based on adaptive in-
formation unified presentation of data and rules.
Applications for artificial intelligence are unlimited. The technology can be used in
many different sectors and branches of the economy.
When most people hear the term “artificial intelligence” in tourism, the first thing
that usually comes to their mind is robots or applications for mobile phones. Howev-
er, nothing could be further from the truth when considering the aspect of AI in the
application to tourism for people with disabilities or using other terms like affordable
tourism, tourism for the disabled, or inclusive tourism.
“Inclusive tourism should be interpreted as social integration," said Scott Ryan,
one of the propagandists and founders of "accessible tourism," and tourism is the most
universal way of social integration. Therefore, it is necessary to modernize the tour-
ism sector, in which the concept of "accessibility of tourism for all" will be consid-
ered in terms of adapting the infrastructure of tourist centers and sightseeing facilities
to the various needs of all people, including the disabled and elderly people, etc. The
level of development of inclusive tourism in our country is minimal and requires
widespread. Having studied the experience of world countries, one can develop and
offer new innovative approaches to the organization of accessible tourism in Russia.
According to the World Health Organization (WHO) estimates, 15% of the world's
population lives with some form of disability. Accessibility for all tourist facilities,
products, and services should be a central part of any responsible and sustainable
tourist policy.
253
The creation of the “Accessible Tourist Destination” international merit badge is
the result of a joint committee of the World Tourism Organization (WTO) and the
ONCE Foundation to the recognition and promotion of accessible tourist destinations.
These goals are to recognize and promote tourist destinations that make great efforts
to ensure that their destination can appeal to any tourist, regardless of physical, senso-
ry, or cognitive abilities.
ATD is annually awarded worldwide by the United Nations specialized agency,
such as the World Tourism Organization. This is not a certificate of accessible desti-
nation, confirming its superiority in this area, but a merit badge, which emphasizes
the initiatives taken so far, as well as the efforts to maintain and improve the level of
accessibility achieved.
An Expert Committee has already been appointed to evaluate materials for the
World Tourism Organization ATD2021. It brings together some of the most recog-
nized experts on universal accessibility in tourism, representing tourist destinations,
consumers, the tourist industry, as well as disabled people organizations (DPO), and
international organizations. As a result of the Expert Committee work, a joint decision
will be made to select a single tourist destination as an example of 2021accessibility.
In addition, the Committee may also decide to make special references to different
types of destinations, depending on the profile of ATD2021 candidates.
“Accessible tourism" allows people with disabilities in terms of mobility, vision,
hearing, and cognitive functions to act independently, fairly, and with dignity, provid-
ing universally designed travel products, services, and the environment (Darcy-
andDickson, nd). According to the European Network of Accessible Tourism (ENAT,
nd), accessible tourism includes:
barrier-free areas: infrastructure and facilities;
transport: by air, land, and sea, suitable for all users;
high-quality services: provided by trained personnel;
events, exhibitions, attractions: everyone can take part in tourism.
Since all tourist services are based on people, their awareness of the subject,
knowledge, and skills are crucial to success. The human factor has been and will be a
key factor in the design of any adapted tourist product because the levels of attention
and care required by these groups must be highly individualized. Social skills (empa-
thy, sociability, assertiveness, etc.) are essential in accessible tourism, as most of
these people will need direct support or assistance in many leisure activities.
With the advent of the Internet, robotics, virtual or augmented reality, and big data,
the technological revolution provides new opportunities to improve the services and
destinations available to tourists. Providing human resources with the necessary digi-
tal skills will help to adjust these services to real and specific needs and different
types and levels of disability or limited mobility.
The level of demand for the adaptation of facilities and equipment in accessible
tourism is high. The "inclusion" strategy of groups of people with disabilities leads to
greater sustainability of initiatives. In this "global" concept, the versatility and adapt-
ability of a tourist offer are perfectly complemented by environmental criteria and
integration of the territories and local population.
254
Accessible tourism allows all people to participate and enjoy tourism. Many people
have access needs, whether they are physically healthy or not. For example, older and
less mobile people have access needs that can be a huge obstacle when traveling or
touring. Thus, accessible tourism is a constant desire to ensure accessibility of tourist
destinations, products, and services for all people, regardless of their physical limita-
tions, disability, or age. Thisincludespublicandprivatetouristfacilities, and services.
Accessible tourism involves collaboration between all stakeholders, governments,
international agencies, tour operators, and end-users, including disabled people and
their organizations. A successful tourist product requires effective partnerships and
cooperation in many sectors nationally, regionally, and internationally.
From idea to implementation, visiting one destination usually involves a variety of
factors, including access to information, different types of long-distance travel, local
transport, accommodation, shopping, and restaurants. Thus, the impact of accessible
tourism extends not only to tourist beneficiaries but also to society as a whole, rein-
forcing accessibility in the social and economic values of society [7,8].
Accessibility is also an important aspect of realizing the rights of the world's aging
population. As we get older, our chances of getting a permanent or temporary disabil-
ity increase. Thus, the emphasis on accessibility can ensure that we can participate
fully in social life in our golden age. Accessibility also benefits pregnant women and
those who are temporary cannot travel.
Improvements in physical and service infrastructure, with a focus on accessibility,
also contribute to a more mindful attitude to different generations in development
planning. For families with young children, accessible infrastructure, especially in
transport, urban planning, and building design, empowers these families to participate
in social and cultural activities [7].
The United Nations is committed to sustainable and equitable development. Of
course, making basic changes to the facility, providing accurate information, and
understanding the needs of disabled people can lead to an increase in the number of
visitors. Improving the availability of tourist services enhances their quality and en-
joyment for all tourists, as well as improves the quality of life in local communities.
The development of the “Tourist Digital Profile” by the Big Data Associations
aimed at identifying the needs of tourists in a particular region and identifying their
unrealized demand. For example, information about travel expenses, travel geo-data,
lists of visited attractions, cafes, and hotels will help the authorities to pay attention to
the "weak points" of resorts and build the necessary infrastructure. The Russians' data
will be anonymized. The project contributes to the development of accessible tourism.
Virtual reality is an important area of AI application in accessible tourism. Virtual
reality is a technologically created world transmitted to man through his senses: vi-
sion, hearing, touch, and others. Virtual reality simulates both impact and impact
reactions. To create a convincing set of reality senses, the computer synthesis of prop-
erties and virtual reality reactions is made in real-time.
The benefits and effects of technology are as follows: time and staff costs saving;
transfer of complex instructions to interactive training; no real damage to equipment
or health in the event of an error; the ability to repeat actions an unlimited number of
times in a training format; standardization of learning and testing conditions. The
255
difficulties of introducing immersive technologies are the following: time for imple-
mentation takes from 3 to 6 months; the cost of the technology; a single educational
platform; the ability and need for regular use of technology; VR/AR systems must be
integrated into a single set of software, the company must be competent enough to
support (Fig. 3).
To reproduce the user's contact with the environment in the most accurate way, the
user interfaces are used, most realistically corresponding to the simulated objects: a
computer steering wheel with pedals, device control handles, a pointer in the form of
a pistol, etc. Virtual reality gloves and hand tracking with video cameras are used for
contactless object control.
Direct connection to the nervous system. The devices described above affect the
human senses, but the data can be transmitted directly to nerve endings, and even
directly to the brain through brain interfaces.
Visiting and exploring new places, especially those that are physically inaccessible
to disabled people, are of particular interest to them. Digital 3D simulation to preserve
heritage sites. A system of calligraphy learning using virtual reality technology. Eval-
uation and analysis of traffic to mass tourist attractions. Visual communication pro-
jects such as animation and game projects depicting the importance of cultural herit-
age through storytelling. Cultural education with the help of virtual reality.

Depending on the purpose of visiting the network, it is possible to distinguish differ-
ent types of virtual tourism: educational, cognitive, entertaining, scientific, exotic.
Each type of virtual tourism is characterized by its type of tourist: virtual vagrants,
extremes, collectors, etc. To some extent, we can speak about the formation of a tour-
ist virtual community.
256
The tourist should be convinced that he would get to the place, which was recom-
mended by the operator. To solve this problem and ensure competitiveness, the tour-
ism business focuses its attention on rapidly developing virtual technologies, namely
3D.
The benefits of introducing virtual technologies are as followers:
the ability to consider all the small details of interest;
clarity of the route, as once it has already been passed virtually;
visualization of the atmosphere of the destination (arrival);
tour operator's timesaving.
Currently, the following apps have been developed: The Grand Canyon Experi-
ence Titans Realities of Space 2.0 EVEREST VR. VR Museum of Fine Art the Blue
Destinations Google Earth VR is one of the top ten mobile apps for tourism. In
2014Artgidjoint the top - the best guide to the artistic life of St. Petersburg and Mos-
cow. Top Trip Tip has combined all Russian tourist resources. Friendly Cities is an
unusual and brand-new mobile guide to the world's most popular cities. Friendly Cit-
ies is a project about small cafes, wine bars, flea markets, festivals, art galleries, and
shops of local designers.
Interactive guidebooks have geolocation and route-building ability, integrate with
social networks, virtual galleries, use the application without a permanent connection
to the network, interactive software, including video, animated graphics, 3D, audio
comments, and circular panoramas. One can introduce marketing tools - promotions,
surveys - into apps. Special counters will allow one to conduct a detailed analysis of
the user's interaction with the content. It is also possible to enter infrastructure infor-
mation of all types for disabled people.
The innovative direction of the hotel industry is the introduction of the Virtual
Concierge system into hotel activities. Guests can use this type of service with the
help of a telephone application, website, TV screen in rooms, or displays of various
types and sizes, which are mounted inside walls and furniture, decorated in elements
of the interior, and installed in the form of free-standing information stands. By plac-
ing the board inaccessible hotel locations, one can show a guest the way to the con-
ference room, restaurant, lobby bar, spa, etc. without concierge help. Content is man-
aged through a Web browser on a computer or tablet. Internet news blocks are auto-
matically updated.
Virtual Concierge functions:
transfer information to any room of the hotel due to the work of audiovisual signs
in a single mode with different hotel management systems;
booking places in a restaurant, spa, etc;
demonstration of the hotel's catalog of offers, restaurant menus;
guest requests to the administrator
showcasing guests through galleries and 3D tours of various hotel services: room
types, restaurants, and bars, meeting rooms, etc.;
providing information about weather, exchange rates, breaking news;
257
with the help of maps, one can pave the route for the guest with the attractions,
restaurants with a certain type of cuisine, the level of city roads congestion before
the trip;
with the help of a TV "virtual concierge" one can work with documents, presenta-
tions, and tables, as well as contact all hotel services;
Control of the system is as intuitive as possible and in many ways similar to the
menu of a smartphone.
Today, the Virtual Concierge system is already used by representatives of such
networks as The Ritz-Carlton», «Marriot», «Westin Hotels & Resorts», «Hyatt Re-
gency», «Hyatt Regency New Orlean», «Andaz 5th Avenue in New York», «Hyatt
Regency Denver Tech Center”), “Fairmont Hotels &Resorts», «Holiday Inn», «Inter-
Continental», «Vander Valk Hotels» (Ne), «Accor» («Novotel»); hotels: «Burj Al
Arab» (Dubai, UAE ), «Denit» (Barcelona, Spain ), “Del Coronado" (Coronado, Cali-
fornia).
Consequently, the Virtual Concierge system has become a new channel of commu-
nication with the customer.
3 Conclusions
Thus, it should be noted that artificial intelligence is a powerful means of data pro-
cessing and can find solutions to complex problems faster than traditional algorithms
written by programmers. Artificial intelligence is gradually becoming a daily routine
and is being introduced into a wide variety of business spheres, including accessible
tourism.
