Today, modern technologies provide incredible opportunities in numerous areas, including the hotel business. This technology creates a deep connection between the guest and the hotel, overturning the usual idea of hospitality. Virtual reality allows you to surprise guests with immersive unique experiences that are not only exciting but also facilitate the activities of the establishments themselves. In this article, we’ll look at how virtual reality revolutionizes the hospitality industry and helps to deliver unparalleled guest experiences. Exploring Diverse Dimensions of VR in Hospitality There are several main areas where virtual reality is most often used in the hotel industry, including virtual tours, staff training, and VR entertainment.  Enhancing Guest Experiences through VR VR hotel tours are one of the most popular directions where virtual reality is typically when dealing with  hospitality. Before checking in, guests can take a trial visit to the property in VR to assess the hotel environment. This technique will help to better understand where exactly they want to stay, in which room, and whether this hotel meets the requirements. “One of the reasons why VR marketing has taken on a viral tone, arises from the fact, that guests will be provided with a hands-on point of view when making an important booking decision. Using such technology clearly illustrates that the property in question is keeping abreast of the latest digital trends. Today, VR tours can be easily placed on an online platform, through the rise of cost-effective software packages,” according to Keystone Hospitality Property Development. For example, the Atlantis Dubai Virtual Tour shows future customers what the hotel looks like, starting with the exterior and ending with the appearance of the hotel rooms. The experience was filmed in the 360o format. Thriving Frontier of VR Entertainment in Hotels Once your guests have checked into their hotel rooms, they should receive high-quality entertainment offered by the hotel chain itself. These can be virtual reality rooms for guests to spend their free time. For example, the Polish spa resort Czarny Potok also has a virtual reality room where visitors can play various games in VR headsets. In addition, virtual reality can be used as a preview of real entertainment available. Before your guest tries, for example, sightseeing, they can get a preview of a tourist destination they could go to. Consider a VR tour of the ancient city of Petra in Jordan.

Discovering Nature’s Beauty through AR and VR Navigating Future of Hotel Reservations through VR Another area of virtual reality that is developing in the hotel industry is VR booking. Similar to virtual sightseeing, a user can see the chosen vacation spot for themselves, though the range of possibilities of VR booking is wider.  So, a VR headset user sees a digital globe of the Earth in front of them and decides on the point where they want to go. Next, they interact with a 3D model of the plane, which clearly shows the seats that can be reserved. Moreover, there is an opportunity to rent a car and choose the price of this rental. With virtual booking, users can select a payment method by scanning and adding a digital credit card. Virtual booking from Amadeus IT Group provides such options to users with VR glasses. VR’s Role in Transforming Hotel Staff Training In the hotel industry, virtual reality is used not only to serve customers but also to improve customer service. Virtual reality training, which fully reproduces the real work environment in digital reality, is an effective tool to improve the efficiency of hotel staff. For example, the Best Western Hotels chain recorded a 71% decrease in the number of customer complaints after the introduction of VR training. Virtual training is already used by the famous Hilton network. In this training, employees use VR headsets to immerse themselves in the digital space that reproduces the hotel.There, they perform various tasks typical for the hotel staff: cleaning the room, preparing a cart with lunch, and checking in guests.    The integration of virtual reality marks a revolutionary step towards improving the guest experience and redefining the hospitality industry. With the introduction of virtual reality in hotels, guests are no longer limited by physical boundaries. Virtual tours of hotels and attractions allow them to go on exciting journeys and explore these places without leaving their homes. Once a decision is made, users can completely organize their own trip through VR booking in a gamified form. Virtual reality in the hospitality industry has also paved the way for more comfortable and faster service with the help of VR training for hotel staff. The combination of technology and hospitality has created a new dimension of travel planning where potential guests can virtually walk through hotel rooms, imagine their stay, and make informed decisions.

This article was written by our CEO Olga Kryvchenko and originally published on Linkedin. To get more biweekly updates about extended reality, subscribe to Olga’s XR Frontiers LinkedIn newsletter. The power of touch has long been recognized as a potent sensory modality. With the rise of Extended Reality (XR) technologies, touch, or more precisely, haptic feedback, has found its profound significance. Especially in hazardous industries, where direct training poses risks, XR combined with haptic feedback offers a revolutionary approach. Understanding Haptic Feedback At its core, haptic feedback simulates the sense of touch and movement. This tactile feedback, when incorporated in digital interfaces or XR environments, provides users with realistic sensations ranging from a gentle breeze to a jolt from a virtual electric shock. The Evolution of Haptic Devices While the rudimentary concept of haptic technology revolves around vibrations, contemporary haptic devices offer far more intricate feedback. – Glove-based Systems: Pioneering the future of touch in XR, these gloves simulate intricate textures, temperatures, and resistances. Users can virtually touch a hot surface or feel the graininess of sand. – Vest Systems: These aren’t your average vests. They’re equipped to simulate everything from the impact of a bullet to the gentle tap on the shoulder. – Treadmills and Platforms: Beyond letting users walk or run in a virtual space, these devices offer gradients, and resistances, and even simulate different terrains. – Haptic Controllers: These handheld devices can simulate weight, resistance, and more. They’re often used in XR setups where precision is required, like machinery operation or surgical training. Spotlight: Some XR Haptic Innovations 1. Manus Meta Gloves: Advanced haptic gloves that simulate intricate tactile experiences within virtual spaces, ideal for hazardous industry simulations. 2. SenseGlove: Offering unparalleled haptic feedback, this device simulates realistic touch sensations, ensuring authentic training experiences in hazardous industries. 3. Electric Haptic Vest: A revolutionary vest that provides electric haptic feedback, enabling users to feel virtual impacts, touches, and temperature changes, enhancing training realism. These innovations are setting the benchmark for immersive XR training in high-risk sectors, ensuring both safety and efficacy. Incorporating Haptics in XR Training for Dangerous Industries Haptic feedback is not just a fancy addition; it’s a necessity in industries where mistakes can be catastrophic. 1. Realistic Hazard Simulation: XR environments equipped with haptic feedback allow trainees to understand and feel dangerous situations, like the rumble of an impending mine collapse or the heat from an electrical malfunction. 2. Skill Refinement: Fine motor skills can be honed in a virtual space. Imagine a trainee learning to operate a chainsaw; with haptic feedback, they can feel the tug, the resistance, and even the vibration, all without the real danger. 3. Emergency Protocols: Virtual emergencies can prepare employees for real-world crises. These drills aren’t just visual or auditory; haptic feedback ensures they are physically intuitive. Looking Ahead: The Future of Haptic XR Training The fusion of haptic devices and XR promises a future where training for even the most hazardous jobs is thorough, intuitive, and above all, safe. As the fidelity of haptic feedback continues to improve, the line between virtual training and real-world operation will further blur, leading to a workforce that’s adept and prepared for any challenges. In an era dominated by technological advancements, haptic feedback stands out as a game-changer for XR training in dangerous industries. It’s not just about seeing or hearing; it’s about feeling, and that tactile element ensures that trainees are not only knowledgeable but are also instinctively prepared for real-world scenarios.

In healthcare, technological advances are constantly changing approaches to patient care and physician training. And augmented and mixed reality are among such innovations that have captured the attention of both healthcare professionals and researchers. Thanks to AR and MR, there are new ways to sharpen the work of surgeons and present educational materials for students and interns who are learning to work with patients. In this article, we will explore in detail the intricacies of mixed and augmented reality in healthcare and explore their applications and benefits. Primary Benefits  Modern hospitals are increasingly paying attention to augmented reality because it provides doctors and patients with such benefits as Improving processes visualization in education. As it has been repeatedly proven, immersive technologies can significantly improve the success rate of students who will become doctors. The first case is a digital visual accompaniment to books on the study of anatomy, which allows you to understand the structure of the human body better. The second one is interaction with a digital human body, which is an alternative to autopsies of real ones in cases when medical students do not have the opportunity to visit a real morgue. In addition, through a smartphone screen or MR glasses, students can independently interact with the digital organs of the body and learn more about their components. Read also: Augmented Reality Books: Next Chapter in Interactive Reading  Reducing the percentage of medical errors. The introduction of immersive technologies in hospitals and medical facilities reduces the percentage of medical errors, some of which can even lead to fatal consequences: from an incorrect diagnosis to an error during surgery. So, 40,000 to 80,000 patients die every year due to doctors’ mistakes. To reduce patient mortality and optimize the process of diagnosis and treatment, doctors are introducing augmented reality for training interns and AR-projection for training and direct operations. Increasing patient engagement. Visual digital content that can be interacted with allows not only professionals but also patients to better familiarize themselves with the processes in their own bodies. And augmented reality can be useful for studying the algorithm of health care and rehabilitation, where immersive technologies transform classic monotonous exercises into an exciting, gamified process. Read also: Virtual Reality is the innovative way of patient’s recovery  Spotlighting the Effective Use Cases of AR and MR AR at the Operating Table: Inspiring Applications Shaping Surgery’s Future With the help of augmented and mixed reality, collaborations between doctors during surgeries become easier and more accessible. Especially when experienced doctors need to advise young interns during complex surgical procedures. Like, for example, the Proximie medical AR platform for professional specialists, which allows them to virtually move into the operating room and consult other specialists from the beginning to the end of a complex procedure. A device, connected to the Internet, allows a doctor not only to see the entire process of the operation but also to superimpose body scans and X-rays on the patient’s body and point out to another specialist the areas that he should pay attention to. How AR and MR Revolutionize Symptoms Recognition in Healthcare Augmented reality training will help doctors determine the symptoms of a patient’s disease in a certain organ of the body. An example of such an application is the EyeDecide app created by OrcaMD, which allows you to simulate the activity of the human eye during a particular disease. This application was created so that doctors could more clearly show patients the consequences of a particular disease. For example the patient can learn about how the eye with cataract disease sees. AR and MR’s Impact on Medical Training Success Virtual and augmented reality training has long proven its effectiveness due to the fact that the employee acquires new knowledge and consolidates new skills in the most realistic environment. AR training for physicians is no exception. Like, for example, the CAE AresAR app that was built for medical students who use Microsoft Hololens 2. In this application, students learn the structure of the human body using the example of a digital copy of it lying on a real hospital bed. Also, doctors and students can interact with digital organs and study not only their structures but also how they work. For example, the video shows students zooming in on a digital model of a beating heart.

Augmented reality can give even greater independence in self-treatment and rehabilitation, with the visual digital content superimposed on the real world, they get more information about the state of their body and get more familiar with instructions on how to behave during a deterioration of health. This option for patients is provided by the Know My Beat AR application, developed by British specialists. With this application, patients can independently monitor their own pulse and also learn to identify the symptoms of fibrillation themselves.   Augmented and mixed reality provides innovative and comfortable treatment of patients in various directions — from surgeons who receive AR instructions in real time to medical students who work with complex anatomical models. Thanks to digital technologies, doctors can quickly and clearly learn the skills of treating patients and reduce the percentage of medical errors. Meanwhile, patients can actively participate in their treatment plans through interactive visualization. As we look to the future, the convergence of AR with healthcare promises even more breakthroughs — from improved diagnostic accuracy to personalized therapeutic interventions. Image: Freepik

In the era of social media and binge-watching series on streaming services, people seem to be gradually forgetting about reading paper books. And this concern is confirmed by statistics from Wordsrated, which shows that in 2022, more than half of Americans have not read a single book. How can you solve this problem and develop modern literature? In this case, augmented reality can come to the rescue, allowing readers to go on interactive journeys blurring the lines between fiction and reality. In addition, AR experiences that appear on the pages are also actively used for educational textbooks, which help teachers better familiarize students with the subject being studied. In this material, you will learn in more detail how modern immersive technologies contribute to the development of a paper book and motivate the audience to read. Augmented Reality Books: Exploring Magic Between Pages and Screens Augmented reality books, also known as a-books, are paper books that contain markers on their pages that activate AR. Immersive digital content is brought to life with the help of smartphone applications. This function allows you to better visualize the concepts that the author of the book wanted to convey to their audience. To activate augmented reality for a book, a reader must download a smartphone app that uses a camera to scan pages with QR codes or 2D images. Thus, a-books combine the additional possibilities of modern digital technologies and the traditionalism of real paper books. For example, specialists at the Institute of Advanced Technologies at the University of Surrey are actively developing books with augmented reality, which will provide additional multimedia information along with the text on the pages. Read also: What’s The Difference Between VR, AR and MR “I’m not suggesting that this is going to be augmenting every single book, but there would be maybe fantasy novels, or user manuals, children’s books where you get all sorts of content coming out of the book; potentially wedding albums, where you could have a very precious item in itself and that would be the link to some multimedia, videos, and things like that,” said Dr. Radu Sporea, senior lecturer of the Institute of Advanced Technologies.  Empowering Next Generation of Learners with AR Books In terms of education, augmented reality provides an opportunity for students to go beyond just reading theoretical material with 2D images. WIth AR, students have a chance to see the material being studied from all angles and even interact with it. Such a function is especially relevant for many subjects, from geometry and physics to foreign languages and history. When children and teenagers study these sciences using augmented reality, their concentration level during the learning process is proven to increase. About 72% of students said they were more likely to participate in an AR-powered studying process.  Read also: Augmented Reality: Secret Weapon for Boosting Your Child’s Creativity and Imagination  For example, an illustrated guide with an augmented reality mobile app was released for Japanese English learners. By pointing the smartphone screen at the pages of the textbook, the student sees the animated characters of the book in front of them in AR and also listens to their dialogue. Thus, augmented reality not only makes learning more interactive but also allows you to save on audio cassettes and discs, which are usually included with textbooks for learning a foreign language. In addition, augmented reality can be useful in learning art, where the visual is a key component. Like, for example, a concept from the Torch company, supplemented the book on the art of Ancient Greece with AR projections of famous sculptures, bas-reliefs, and other works. Instead of just reading about these works and seeing photos that only show one angle of them, readers can explore the statues in their entirety and from all angles in the AR mode. Exploring AR Books in Fiction: Where Imagination Takes Flight Speaking about fiction, the main function of the book is to immerse readers in the world skillfully written by the author, to convey a certain moral of the story, or simply entertain and distract the reader from routine. Augmented reality for books makes the story more three-dimensional and allows you to more clearly show the author’s original idea and immerse the reader in his imagination. In addition, augmented reality for books is an effective and interesting way to attract the attention of young people to books. According to the American Psychological Association, one in three teens in America hasn’t read a book in a year, attributing it to social media and gaming. The gamified process of reading a book, whether it is a standard fiction or a comic book, can interest a young audience in reading. In this way, they not only read textual descriptions but also see three-dimensional images of the characters and their environment. Nine out of ten children said they would read more books if they contained augmented reality. Moreover, AR is able to attract the audience of a book franchise that has already gained worldwide popularity. In 2012, a book with augmented reality “Wonderbook™: Book of Spells” based on the universe of “Harry Potter” by J. K. Rowling was released for PlayStation. A specially prepared Wonderbook (marked book) activates digital AR content that transforms the book into an ancient spellbook. The experience is possible with the Playstation Eye camera and a controller that turns into a magic wand in augmented reality. Augmented reality has created new opportunities for audiences who can read books and interact with digital visual content on their pages. Thus, the gap between the author’s idea and the reader’s imagination is greatly reduced when they see the universe and its characters. For teachers, augmented reality is a convenient tool that helps to more easily convey the studied subject, thereby positively affecting the concentration of students. AR technology is an effective way to support the book business, as augmented reality complements the traditional reading experience instead of replacing it. Image: Freepik

This article was written by our CEO Olga Kryvchenko and originally published on Linkedin. To get more biweekly updates about extended reality, subscribe to Olga’s XR Frontiers LinkedIn newsletter. Hello, LinkedIn readers! Today, I want to dive into an exciting topic that’s been rippling through the landscape of education – Extended Reality (XR). Let’s start with a quick clarification. By XR, I mean the whole suite of technologies that include Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). Each of these has distinct features, but they all share a common goal: to blend the digital world with the real world in meaningful ways. Now, there’s been a lot of buzz lately about how XR is set to replace traditional classroom settings and the teacher’s role within it. However, I’d like to gently steer the conversation in a different direction. XR isn’t here to replace our beloved teachers but to adjust and enhance the learning process. It’s a tool, not a teacher substitute. To help illustrate this, I’ll be sharing a few examples from across the YouTube landscape. First, let’s take a look at the CurioXR channel on YouTube. This fantastic platform creates XR educational content that breaks complex topics down into immersive experiences. Take, for example, their interactive lessons on the solar system. Students can walk around the planets, watching as the solar system spins and works in real-time. Next, let’s discuss an impressive use of XR in the field of chemistry. I’d like to direct your attention to this VR Chemistry lessons app showcased on YouTube. Imagine being a student and having the ability to interact with atomic models in 3D, conduct experiments without the risk of dangerous chemicals, and see chemical reactions unfold right before your eyes. It’s an extraordinary way to deepen understanding and curiosity. Yet, this too doesn’t replace the teacher; it’s a tool that provides teachers with a new way to engage students and explain complex chemistry concepts more effectively. Another great example is the YouTube video ‘VR in Education: The Future of Learning,’ which explores the benefits of XR in the classroom. It shows how students can dive into history by walking through historical sites or explore human anatomy by stepping inside a larger-than-life human body. Again, it’s not about replacing teachers but augmenting the learning process. XR can transport students to places textbooks cannot and give them firsthand experiences that enhance their understanding. It provides a depth of learning that’s hard to achieve with traditional methods alone. Moreover, XR can accommodate different learning styles better. Some students learn by doing, some by seeing, and others by hearing. With XR, all these needs can be met in one place, making education more inclusive and accessible. But, despite the promise of XR, it’s essential to remember that it’s just another tool in our educational arsenal. No technology can replace the human connection, empathy, understanding, and passion a teacher brings to the classroom. The purpose of XR isn’t to replace these aspects but to support them. To conclude, it’s clear that XR has enormous potential to transform how we educate. However, this doesn’t mean it will replace our teachers. Instead, it’s set to work in tandem with traditional learning methods, adjusting the process to make it more engaging, immersive, and effective. Let’s look forward to an exciting future where technology and teachers work hand in hand to shape the minds of tomorrow! If you’ve had experiences with XR in education or have thoughts on its role in the future of learning, please share in the comments below. It’s always great to hear from you!  Image: Freepik

In this article, we will explore the impact of augmented and virtual reality on national parks, specifically how they are changing our experience of visiting natural landscapes. We focus on free virtual tours that allow us to see the beauty of national parks without leaving home. We will also reveal the main advantages of augmented reality, which enrich the visiting of real parks with the help of digital content with interesting information. In particular, we will share our experience of creating tourist VR excursions using the example of the Carpathian Mountains Virtual Tour and Medieval Fortress Virtual Journey. We will also explore other famous AR/VR use cases, e.g., the State Parks of California, giving us a unique perspective on our national parks’ historical and ecological significance. Discovering Benefits of AR and VR in National Parks Virtual and augmented reality offer such benefits to national parks as Getting informative content on the spot. When visiting parks and other historical places, visitors usually don’t know about this or that type of plant or even in which part of the park they are. With the help of an AR application, a tourist can simply point the screen at a particular plant and get additional information about it. Read also: The Ways AR Redefines Modern Tourism  Speaking about orientation in place, AR navigation will come in handy here, which guides the tourist in the right direction with the help of digital pointers. Read also: From Outdoors to Indoors: AR Navigation as Game-Changer Visiting places that aren’t accessible for you. During the COVID-19 pandemic and home isolation, virtual tours of museums or national parks were one of the popular alternatives to visiting real tourist locations. Even though the pandemic began to gradually fade away, virtual tours continue to be relevant. By visiting free tours on museums or park websites, an Internet user saves money on the ticket, car fuel, and transportation. Especially when a person does not always have an opportunity to get to the place where, perhaps, he would like to go. “The advantage is that you can go somewhere and experience the same feelings without leaving your home. Virtual guides have musical accompaniment, the effect of presence thus allows you to immerse yourself in the environment. This is all about VR. Plus, not all of us can go to Papua New Guinea or somewhere else to look at bamboo, baobabs, etc. Or go on safari. Therefore, these are opportunities to visit somewhere without spending additional funds,” said Oleksandr Ivanov, project manager of Qualium Systems. Drawing attention to ecology, rare plants and animals. As you know, there are more than 35,000 species of endangered plants and animals in the world, 99% of which are endangered due to human activities. With virtual and augmented reality for parks that are the home for these species of animals, it becomes possible to tell about these endangered species to a wider audience. As of July 2023, there are almost 7 billion people in the world who have smartphones, which is more than 86% of the entire population of the planet.  Qualium System’s Virtual Tours of National Parks Qualium Systems has great experience in developing VR excursions. Carpathian Mountains Virtual Tour is an application for Meta Quest, created as part of The World Of Carpathian Rosettes — Activities For Preserving The Cultural Uniqueness Of The Carpathians project by the Euroregion Carpathians — Ukraine association with the financial support of the European Union. The main goal of this program is to preserve the cultural uniqueness of the Ukrainian Carpathians. The main challenge in the development of this virtual tour was to introduce more than 260 photo and video materials into the program while providing the VR headset users with such an experience as if they were visiting a real museum. In this application, a tourist can explore virtual settlements in the Carpathians, both with the effect of presence in these settlements and from a bird’s eye view. There is also the option of a “bicycle trip” available. A tourist can “ride” along the Franko route, which is a path in the forest, famous Ukrainian poet Ivan Franko liked to travel. Also, our developers are working on another virtual tour of the medieval fortress in the Ukrainian town of Tustan. Unlike the previous tour, a VR headset user will not only be able to see the digital environment with exhibits but also interact with them. “With the help of VR, you can not only be there, in that museum, but also take the artifacts, examine, bring them up to your forehead. You could see everything down to every crack,” said Oleksandr Ivanov, project manager of Qualium Systems. Unveiling Diverse Use Cases of AR and VR in National Parks Our company pays attention to virtual tours and giving people the opportunity to see places that are inaccessible to them due to various circumstances. We constantly monitor the latest trends in the modern IT industry, and there are other famous examples that will be mentioned later. Virtual Reality Adventures in California State Parks The California Department of Parks and Recreation has introduced virtual and augmented reality tours for 9 parks located in the state of California. In the Virtual Adventurer mobile app, tourists get a guided tour that tells the story of each of the parks, including Colonel Allensworth State Historic Park, Montana de Oro State Park, Old Town San Diego Historic Park, and others. Moreover, futuristic holograms and 3D reconstructions are also involved. “The app also supports and enhances the department’s Reexamining Our Past Initiative by developing content for parks that tells a more complete, accurate, and inclusive history of people and places,” said California State Parks Director Armando Quintero.  Great Barrier Reef’s Virtual Realms As mentioned above, virtual excursions allow gadget users to get to places they would be unlikely to get to in real life. The same is true for the underwater attractions. Not every tourist wants to spend their time and money not only to reach, for example,…

Spatial computing is a fast-growing field that is set to create a new way of interacting with the world around us. This technology has the potential to revolutionize many industries, from healthcare and education to manufacturing and more. The potential is seen by such well-known companies as Apple, Meta, Magic Leap, and others, which work with spatial computing and mixed, augmented, and virtual reality. By 2032, the total value of the spatial computing market will grow to more than $512 billion, compared to $87.5 billion in 2022. In this article, we will take a closer look at the concept of spatial computing and try to explain how it differs from mixed reality, as well as its potential impact on various industries.  Rise of Spatial Computing.  Historical Overview According to Wikipedia, the term “spatial computing” was first coined in 2003, in the eponymous research paper by Simon Greenwold, a former researcher in the Aesthetics and Computation group at the MIT Media Lab and current head of Story As… Simon Greenwald. The original definition of spatial computing is “a human-machine interaction in which the machine retains and manipulates referents to real objects and spaces”. With the development of immersive technologies, modern spatial computing primarily describes a direct human interaction with technologies and digital content. For example, spatial computing involves the use of gestures, head and eye movements, voice commands and their integration into the digital interface of a device, such as the latest Apple Vision Pro. As defined by Apple, spatial computing is a technology that seamlessly blends digital content with the real world. For example, this technology is useful for remote work, games, or movies, where a headset user can expand the screen to gigantic dimensions, making home viewing more like a real cinema experience. Spatial Computing vs. Mixed Reality. Understanding Key Differences There is a popular opinion that the term “spatial computing” is not so innovative. According to some experts, this technology works on the principle of mixed reality, popularized by Microsoft with the help of Hololens MR glasses. And indeed, according to Vladimir Grygoriev, Qualium Systems tech lead, both mixed reality and spatial computing impose digital objects on the real space, considering the physics of the space. “In fact, many devices already do the same spatial mapping as Apple does. And what is Apple planning to present, what is the main innovation and the difference? First, they want to add such image quality that a person will not feel the artificiality of it on devices. Meaning, you have a cup standing in front of you, and when being touched, it falls, spills, and breaks. But when you take off your glasses, it does not even exist,” Grygoriev said. On the other hand, when releasing the newest headset, Apple plans to use “spatial computing” as a collective term for other areas, such as spatial rendering, spatial mapping, spatial interactions, etc. The innovation of Vision Pro is also about its functionality, with the interface allowing you to turn on several applications at the same time. “Apple will provide an option, that allows you to run a bunch of applications in small windows in your room. It will also give other people access to your space. You can make 5–10 different screens, where various types of content are being sheared. Then you can close some apps and, wearing a headset, go from the dining room to the kitchen while checking your online chat,” Grygoriev said. Implementing Spatial Computing and Mixed Reality Spatial computing is used in such areas as 3D Modeling. Due to the fact that spatial computing technology can seamlessly integrate digital objects into real space, a user of an AR/VR headset can design a 3D model of their future project, whether it is a building, a car, a room, etc. With spatial computing, a user has the ability to zoom in and out a digital object, view it from all sides, etc. This gives the user the opportunity to see the future construction in more detail and correct errors that can cause serious financial losses. For example, in this video, an engineer wearing Hololens 2 glasses projects a future car model on his desk. Remote collaboration. With spatial computing and mixed reality, employees who are in different places can collaborate and see each other. It can be either a completely virtual environment (for example, a virtual office) or an MR option, in which the employee can see a digital screen with the image of their colleague or his own digital avatar in XR-glasses, without leaving a physical workplace. One of the interesting cases of remote collaboration through MR is the concept of mixed reality from the Airbus airline company. The company’s employees work with customers on the aircraft’s family cabin design. The concept offers a full recreation of the virtual cabin on portable devices, as well as the possibility of collective work of MR-glasses users on a digital model of the cabin superimposed on the real world. Training and skill development. Mixed reality and spatial computing have found their application for training employees in various fields. The convenience of MR training lies in the fact that the employee acquires practical skills at work with the help of digital instructions that are smoothly superimposed on the workplace. Mixed reality and spatial computing are not only implemented to train doctors and factory workers. For example, mixed reality is used to train military pilots for the F-16, F-18, and F-35 fighter jets. During training from Varjo, the pilot sits in the cockpit with a real control panel. A pilot, while training in MR glasses, sees a real image of himself in the cockpit alongside a virtual environment that reproduces the training ground. Spatial Computing Technologies. Where and How They’re Making an Impact  Empowering Medical Professionals: Spatial Computing’s Role Spatial computing is already finding its application in the field of medicine. This technology allows you to create interactive digital twins of patients, so that doctors can examine the body from any angle and…
