Two years ago, we developed an AR application that allows users to try on different glasses in real time based on the shape of the face. Then the main difficulty was to accurately determine the shape of the head in order to give appropriate recommendations for the selection of the shape of the glasses. It was also necessary to implement a clear positioning of glasses on the face when the user moves his head. Two years have passed. Technologies are actively developing. We decided to transfer the functionality of our application to the web using WebAR. There are several reasons for this: 1. User-friendliness The advantage of WebAR over an application is that nothing needs to be downloaded. The module can be integrated into any site and allow users to try on glasses in augmented reality right in the browser, using either a mobile or desktop computer. It is also convenient for the customer, since there is no need to develop an application separately for Android and iOS. 2. Recognition speed Two years ago, facial recognition on the web was only possible at a low speed, about 5 frames per second, which made it almost impossible to develop solutions for it. For comparison, in applications, this figure was 30-40 frames per second. Currently, the recognition rate for the web is 30 frames per second. This is quite enough for correct operation. 3. Technology Previously, there were few libraries that allow face recognition. Now there are new options you can choose. We used TensorFlow, namely two neural networks for specific tasks: tracking the position of the face and determining its shape. To do this, we developed our own algorithm that creates and predicts all the key points of the face and the distance between them, which allows the system to determine the shape of the face with an accuracy of 95.8%. It is based on the rules of facial geometry and proportions used by artists. If you want to develop an AR solution for face recognition, human hands or other objects, then it is better to be done on the web. In addition to the fact that now there are all technological capabilities for this, you also make it easier for users to use your solution: there is no need to download and install applications, you can integrate it into any site as a separate module.

Coaches, teams, and athletes use virtual reality as an effective way to train skills in boxing, golf, football, tennis, etc.  The US athletes use VR the most. By 2031, the US VR sports market will have reached 56,7 USD billion.  The way VR sports training is applied Virtual reality for sports training is primarily called to improve practical skills. For example, professional boxers and amateurs can train in the VR app The Thrill of the Fight for Oculus Quest. In this app, a player can beat a virtual punching bag and compete with an opponent in the ring. In the game, an athlete can move around the room and punch, similar to a real-life ring, which enhances the immersion effect. The Thrill of the Fight also helps players improve their virtual rival’s abilities: increase their speed, punch power, ability to dodge, stamina during the fight, and more. The fight with a rival could last up to twelve rounds.  With the help of VR, athletes can develop necessary tactical skills required for car racing and team games. German football association has gone into partnership with Beyond Sports to design VR and AR cognitive and tactical training.  In virtual reality, football players enhance their abilities to make decisions during the game and improve the awareness of their position on the field. This training program also contains in-game scenario development and time-pressured tasks, thus helping to develop athletes’ psychological skills. Moreover, VR is applied to athletes’ physical training. Using the VR app Move for Oculus, a sportsman can track the number of exercises and burned calories, during the training and after it. A player can see the tournament table with daily statistics and the list of most recently used programs.  Also, athletes can use virtual reality for physical recovery after serious injuries. Gamified exercises are designed to recover muscle functions and pain decrease. More detailed information about VR apps for rehabilitation you can read here.  The main advantages of VR sports training The main advantages of virtual reality for sports training include the following: Safe training environment  Doctor Ancret Szpak from the University of South Australia carried out an experiment to train and estimate abilities of 57 volunteers, who played VR game Eleven: Table Tennis.  “Our research shows the potential that VR sports training can have in real-world settings,” said Szpak. “The real benefit is an ability to learn and practice tasks that may be logistically difficult, dangerous or impractical to do in the real world.”  VR provides gamified sports training With FitXR app, an athlete can have a wide range of gamified workout programs like boxing, dancing, and high-intensity interval training (HIIT). In VR programs, a player can hit digital balls by hands or repeat dance moves after virtual instructor. Athletes can also choose their own personal real-life coach, who can guide and motivate them during VR sports training. Virtual reality can help reduce pain and relieve training process Maria Matsangidou, a doctoral researcher in the School of Engineering and Digital Arts at the University of Kent in the United Kingdom, conducted an experiment on VR influence on pain level and athletes’ stamina. She asked 80 volunteers to do biceps exercise and hold the weight as long as possible.  One half of the athletes wore VR headset during the workouts, another half didn’t. Research showed that during heavyweight lift, pain level of athletes with VR headset was 10% lower, compared to those who trained with no VR equipment. Also, sportsmen who trained in the virtual reality, could hold the weight 2 minutes longer.  Ensuring realism during virtual reality sports training The app  VR Tennis Training Simulator for Oculus Quest provides realistic virtual gaming experience. A customized engine was designed to create maximally plausible recreation of the physics of the tennis ball movement. It takes into account such factors like side wind, racket string tension, and how the ball acts after it hit the racket and the floor.  Conclusion Gamified process of virtual reality can enhance athletes’ stamina and improve their physical, tactical, and psychological skills. Realistic virtual environment helps sportsmen train at any place, regardless of the weather, special equipment availability, and training real-life space. 

Introduction VR usage provides new possibilities for museums to demonstrate their own exhibits. Also, virtual reality helps museums to create a new, more interesting experience, so visitors could understand famous artists’ works more deeply.  In virtual reality, you can demonstrate digital copies of famous pieces of art or design non-available or non-existing objects. Along with modern VR headset possibilities, museums can create a realistic, amusing, and easily accessible experience for museum visitors.  More than 2000 museums apply virtual reality technology, including the Parisian Louvre, National Gallery, Vatican Museums, etc.  VR is the new way to see the art Virtual reality is a creative platform for museums and other institutions, where exhibitions are held. VR allows you not only to show the exact digital copy of the piece of art, but also to see it from a different perspective. The Night Cafe: A VR Tribute to Vincent Van Gogh for Oculus Rift is a bright example of this kind of a VR exhibition. This app helps VR headset user immerse in famous Vincent Van Gogh painting «The Night Cafe». Using this app, a visitor get straight into the very same picture, where they can see the drawn objects from a different angle. The immersion effect is enhanced by animated pictures of people in a cafe and the chandeliers’ light which shimmers with living strokes of paint.  VR as a remote way to see national parks In addition, VR is also applied for remote virtual excursions to famous national parks. Fulufjället Virtual Tour is only the first part of the Virtual National Parks by IVAR Studios. The main purpose of the VR excursion is to provide free access to Fulufjället’s natural attractions to users around the world. In general, IVAR Studios plans to design VR excursions for 30 Swedish national parks. Fulufjället National Park is known by Njupeskär, the Sweden’s tallest  waterfall, on the Njupån river. The total height of the waterfall is 125 meters. A VR park visitor can see the spruce, also known as the «Old Tjikko». It is more than 9 550 years old and considered the world’s oldest tree.  VR as a way to recreate historical places With virtual reality, museums are capable to recreate historically important places, which are significantly changed or don’t exist anymore. For example, Tate Britain designed the VR exhibition Modigliani VR: The Ochre Atelier, dedicated to a famous Italian painter and sculptor Amedeo Modigliani. The exhibit lets users see a virtual version of a Parisian artist’s studio in the way it was back in 1919. The studio still exists, but today its interior is significantly changed. VR is the way to restore the lost art Museums also use VR for saving destroyed and stolen pieces of art in a digital format. On 18 March 1990, two robbers, disguised as policemen, stole 13 paintings worth 300 US dollars from The Isabella Stewart Gardner Museum. These pieces of art and criminals were never found. However, Ziv Schneider, a multimedia artist and designer, developed lost paintings in the VR Museum of Stolen Art, where the digital copies of missing pictures are shown.  The virtual museum also has two additional rooms, where visitors can look at pieces of art stolen from the National Museums of Iraq and Afghanistan. After the war in Iraq began, more than 14,000 exhibits has been stolen from the state’s museum. This theft is considered one of the largest art thefts in history. Conclusion Worldwide popular museums in Great Britain, France, and the USA use VR not only for remote exhibitions. Virtual reality helps visitors to change their perception of art. Also, VR gives us a chance to see missing pieces of art. And it’s just a small part of the possibilities of virtual reality, which changes the world around us. 

Metaverse is based on virtual and augmented reality. It’s a virtual world, where people can interact, communicate, and work, using digital avatars. Experts have different opinions on the metaverse future. Some consider it as an Internet successor and predict the prospective future. Others have more cautious opinions and point out possible issues with privacy violations and confidential information leaks.  This innovative concept is invested the most by worldwide companies, like Facebook (Meta), Apple, Tencent, Roblox, Unity, etc.  In 2022, the metaverse global market is estimated at 110 USD billion. Global Industry Analysts predict global metaverse market cost will have increased to 758 USD billion by 2026.   Naturally, prospects of metaverse development spark interest both in private companies and countries’ governments around the world. Metaverse investment in the United Arabian Emirates (Dubai) This year, Sheikh Hamdan bin Mohammed bin Rashid Al-Maktoum, the crown prince of Dubai and chairman of the Dubai Executive Council, announced the launch of the new city metaverse strategy. The main purpose of the strategy is to improve Web3 technology, develop new apps, create new government work, and develop these important fields, like tourism, healthcare, education, retail, law, and remote work. Metaverse strategy aims to contribute to the national budget a billion USD and create 40 thousand new workplaces. “We launched the Dubai Metaverse Strategy today, which aims to foster innovation in new technology. Dubai is home to over 1,000 companies operating in the metaverse and blockchain sector, which contributes $500m to our national economy”,  the prince said. “With the early adoption of metaverse technology, Dubai seeks to become one of the top 10 metaverse economies and a global front-runner in adopting digital solutions”.  Metaverse investment in Spain Spain’s government has contributed 3,8 USD million to support small and medium-sized businesses, that work at experimental creation in the metaverse and Web3 fields. The state ministry of economy and digital transformation said the first money will be transferred to companies that produce new content in the gaming and audiovisual industry.  The government’s financial aid is part of the program for the development of Spain as an audiovisual industry center. This program is part of the strategy Digital Spain 2026.  Metaverse support in China (Shanghai) In July, the government of Shanghai, China’s biggest city by population, issued the document, which contains plans of turning the city into an important center of metaverse industry worth 52 USD billion by the end of 2025.  This plan also includes the development of 10 companies, that have a chance to compete in the international market, and the foundation of 1000 new enterprises, which will work in the metaverse industry. Metaverse support in South Korea The Korean government will start to invest 177 USD million in metaverse development. The main investment purpose is to kickstart the national metaverse industry and the development of new companies that work on VR and Web3. That was announced by the minister of science and information and communication technologies of South Korea, Lim Hyesook. According to him, the metaverse is «an uncharted digital continent with indefinite potential».  The investment is a part of the new state’s main course to engage its citizens to do a full transition into digital reality. Korean metaverse will look like «an extended virtual world» with additional media and education sectors. Conclusion The metaverse is a new concept, which is in the early development stages. Nevertheless, many countries’ governments around the world are interested in this innovation, since the metaverse gives new possibilities to prospective business fields and creates new workplaces. 

Nowadays, worldwide brands like Dior, Swarowski, and Ferragamo use virtual and augmented reality as a successful way to promote their items and attract clients who want to get more visual content and do sophisticated shopping.  Market Research Future predicts the increase of the cost of global virtual reality in retail to USD 20.9 billion by 2023. In this post, we will tell about XR solutions that influence retail success right now. How AR influences retail’s success and customer service AR technology is used in many fields of retail. Virtual try-on is one of them. It’s a technology which lets a customer “try on” one or a few virtual items. An AR app scans the body and face parameters to create more realistic item projections and improve other purchase recommendations. With AR technology, a customer has the possibility to create a full virtual look. It can help them to get a better understanding of whether this piece of clothes will suit them. In our previous post, we mentioned virtual try-on examples by Adidas and 3DLOOK.  MOSCOT has launched a virtual try-on where their customers can wear  3D models of glasses. According to the research, 61% of interviewed US customers said they preferred making purchases in shops with augmented reality services. The other 40% of customers said they are ready to pay more for an item if they see it in AR programs. Speaking about MOSCOT’s overall revenue, it increased by 174% after the launch of the AR try-on.   Providing customers with convenient shop navigation is another direction of the AR technology. More than 60% of interviewed Americans said they would like to use the AR technology to save the time they usually spend searching for a product. Augmented reality navigation gives a customer a more interesting, improved, and faster shopping experience. After scanning the special code on the floor, poster, or any other material object, a customer sees a virtual 3D arrow on a gadget screen, and this arrow leads them through the store. This technology also finds an exact location of a client with high accuracy. AR navigation is currently used in the ARKit app for iOS and ARCore for Android.  How VR works in retail Virtual reality in retail is applied for customer immersion in a virtual shop, which is a 3D copy of a real one. With this possibility, a customer can walk through the shop in VR glasses and add items to the basket.  Christian Dior also attracts clients with its VR elite cosmetics shop. Swarowski with the support of a Mastercard designed VR app, which lets customers register a Masterpass account and do online purchases of designer home items in the virtual shop. “At Mastercard, our goal is to provide consumers with the choice to shop when they want, how they want, in a manner that is as seamless and secure as possible”, said Linda Kirkpatrick, EVP of Merchants & Acceptance, Mastercard.  “This means that merchants need to be able to engage their customers across multiple, technology platforms – in-store, online, in-app, and via virtual and augmented reality”.  According to the statistics, every fifth American used VR technology, at least, once in a lifetime. Another 50% of Internet users said they take purchase decisions using VR shops. One of the secrets of the successful use of VR by retail companies is direct contact with customers who understand modern technologies. VR/AR retail apps examples Ferragamo designed a virtual boutique which recreates Italian villa rooms used as a set for filming «It’s Movie O’Clock» video for the Christmas campaign.  All three VR shop rooms contain clothes and accessories available online.  After you click on the chosen item, the window appears. It has the item’s price, characteristics, and other purchase recommendations. You can choose the right size of the item and its number, and add it to the cart. Moreover, you can see pictures on virtual walls. If you click on a picture, you can watch episodes of the original promotional video.  FindYourGlasses APP is one of our latest cases. This smartphone app lets customers try on virtual glasses before purchasing. FindYourGlasses scans a face to define its exact shape and proportions. And then, the program automatically chooses the most suitable models of glasses.   For this app, we customized our own algorithm based on geometry and proportions used by artists. This algorithm can define and predict the main traits of the face with an accuracy of more than 95%. And with the help of a face tracking module, virtual glasses stay exactly where they should be. Conclusion XR technology is in great demand in retail. With virtual and augmented reality, brands can encourage their customers to buy certain products and guarantee the most convenient and safe shopping.

Mental disorders cost the global economy approximately US $1 trillion per year as a loss of productivity. That data comes from Worldwide Health Organization which also predicts mental health conditions to become a disease burden to the worldwide community by 2030. These statistics cause concerns, and today numerous doctors will try to find a way to treat people’s mental health. XR technology usage is considered to be one of the prominent ways to cure anxiety, depression, and other disorders. COVID-19 influence on VR therapy development COVID-19 pandemic quite significantly influenced the minds of adults and children. So, according to the Centers for Disease Control and Prevention poll, more than 37% of schoolchildren said they struggled with anxiety, depression, and stress due to the pandemic.  In addition, the pandemic has contributed to changes in the format of healthcare facilities’ work. Due to the shut-down of schools and offices, offline psychotherapist visits respectively decreased to 70%. As of June 2020, remote mental health consultations increased up to 6558%. Actually, this is one of the factors in the AR and VR mental treatment development nowadays.  Kinds of VR mental health treatment 3.5% of Americans are proven to be diagnosed with post-traumatic stress disorder every year. It’s not only about war veterans, people of different races, ethnicities, and occupations face this problem. For the PTSD treatment, virtual reality is used for the recreation of situations where the traumatic event happened. During VR therapy, a patient is in a safe and controlled environment under the supervision of specialists who can stop the simulation or limit the negative impact of a trigger. According to the study, the first PTSD symptoms patients experience start to fade away in 3 months after the VR therapy.  Also, VR and AR are applied for phobia treatment. From 7 to 9% of people are afraid of snakes, spiders, and dogs. And 4% of people are suffering from claustrophobia, while 5% of patients are afraid of height. With the help of virtual and augmented reality, specialists can recreate deadly and terrifying situations in a controlled environment. For example, you can create a simulation of a ten-storey building, a forest fire, etc. If a patient is scared of insects and small animals like rats, spiders, and cockroaches, a psychotherapist can use mobile AR applications with 3D projections of objects a patient is afraid of. In 2021, Otago University in New Zealand successfully tested a new VR application, oVRcome, to treat different phobias. 129 volunteers aged from 18 to 54 years were treated with combined cognitive and VR therapy for 6 weeks. Test results indicated that phobia symptoms decreased to 75% in patients.  Examples of mental health applications For example, Recovery VR designed applications for calming the nervous system and meditation. The company offers these programs to clients: guided meditations — the program contains 20 guided meditations which can be done in 50 virtual locations like space, nature, psychedelic areas, etc. The main targets of the meditations are body relaxation, anxiety level reduction, pain decrease, and calming of the mind. Specialists recommend patients do some meditations before physical recovery training. By the way, Recovery VR also designed a number of VR apps for patients’ physical recovery, you can read about them here. nature therapy — with a VR headset, a patient can walk through tropical beaches, forests, or city quays. This app is perfect for bed patients or those who can’t walk outside. British company Enlighten, with the help of Staffordshire university, designed the mobile AR app Mental Health Mentor for high schoolers and college students. Every teenager aged 14-19 years old can scan the code placed on school diaries, posters, postcards, and other material stuff. Then, a student gets their own 3D-mentor, whose design was inspired by anime. An avatar’s image can be changed to look like a user, including all racial and ethnic-specific traits. A virtual mentor asks a student about their well-being and consults them on anxiety, depression, bullying, etc. Also, the mentor can recommend a mental help center and give a quick way to contact close friends, teachers, or parents. If a student feels devastated and has suicidal thoughts, the app with an AR mentor gives them an emergency call button to the mental help center. «We had this idea before the pandemic but by the time the project started, it seemed even more fitting, with the school closures and the uncertainty that young people have been facing. Stress levels are much higher than they would be normally, so I think it’s going to have a massive impact», Enlighten founder and director Suzanne Edwards told.  Conclusion Day by day, the need for XR technologies in mental health treatment is increasing. With the help of virtual and augmented reality, a patient can overcome fear in a fully controlled environment. Also, AR/VR gives them the possibility to relax with the immersion in a virtual simulation of a tropical beach or quiet forest. 

Today, students use different ways to consume information. YouTube, Instagram, and TikTok offer a new experience of interaction with content where visuals are prevailing:  short videos, social media posts, and other kinds of fast content. In 2022, more than a half of the Earth population uses social media. It also affects student achievement, since school schedules are mostly organized using methods designed long before the existence of modern social media.   That’s why AR and VR are gradually applying to educational institutions. These technologies  can simplify learning exact and humanitarian sciences and help modern generations to concentrate during lessons.  What’s wrong with traditional way of teaching Today, traditional ways of teaching are gradually losing their efficiency. Classic school schedule requires students to keep up with the teacher’s speech and writings on a blackboard. However, 74% of millennials and Gen Z said they were  constantly distracted by  other things during work and study. 36% of them said they spent more than two hours of their work and study time checking news feeds on smartphones. This is due to the fact that the information flow has significantly accelerated, and the whole world gradually transfers data in the digital world. Moreover, modern youth spends, on average,  less than a second on a web page if it’s not opening fast enough. Also, people usually keep 5 opened tabs in a browser for the second look. And, according to Time, the average internet user spends 15 seconds on a web page. It explains why modern children are losing interest in textbooks and slowly becoming demotivated at learning school subjects. Especially with the emergence of YouTube and TikTok that give children and teenagers fast information with bold and understandable visuals. That’s why internet medias like MTV, Mic, and Newsfeed are creating more video content and paying less attention to making longreads.  The way augmented and virtual reality help education Modern schools encourage students  to get educated with AR and VR technologies. According to statistics of science magazine Annals of Anatomy – Anatomischer Anzeiger, more than 80% of students felt more motivated to study after AR lessons.  These programs and applications make the studying process more interesting due to immersion in the virtual and augmented reality. With AR and VR, a student can see virtual molecules and planets, make a shot with a 16th century musket, and hear dinosaurs roar. Virtual trips to historical ages or the world of atoms and molecules can help students to understand a subject better and learn new skills. 93% of  students said they improved their knowledge of school subjects after AR classes.  Doctor Mihye Won, researcher and Senior Lecturer in the School of Education at Curtin, said that VR programs for learning chemistry let students see and comprehend the molecular world. «VR gives a superior sense of what is happening in the molecular world – you can zoom in and out, and move around in an intuitive way. It makes it much easier to see molecular structures and key parts of a reaction, which is not done as well via other modes», said Won. Moreover, the virtual and augmented reality also gives a possibility to organize lessons both at school and at home. Remote lessons became more relevant when the  COVID-19 pandemic began. According to 2021-2022 statistics, 95% of British schools have all the necessary equipment for remote AR and VR lessons.). Also, 61% of education workers say the number of content for online studying will increase more than any kind of resources and technologies. AR and VR education apps There is a big number of AR and VR programs and applications which are designed to enhance studying for modern children and teenagers.  Virtual reality in history education BBC VR App is designed to immerse students into key historical events. The report of British radio correspondent Wynford Vaughan-Thomas from World War II is one of these events. Vaughan-Thomas made radio broadcast straight from British fighter plane,  which took part in bomb shelling of Nazi Germany in September 1943. Virtual simulation recreates the historical night from the sight of a VR headset user, who stays at a plane board during the whole trip. Also, there’s an original Vaughan-Thomas radio broadcast used in this app, where the journalist himself describes the raid to Germany as “the most beautifully horrible view I’ve ever seen”.  AR in mathematics and other school subjects  For those who have difficulties with learning exact sciences, MergeEdu developed the AR program Merge Cube to explore 3D figures. It’s a special cube, which interacts with smartphone applications and shows three-dimensional pictures on a gadget’s screen. With Merge Cube, a student can learn more about body parts, planets of the Solar System, geometrical figures, etc. AR objects can be zoomed in and out, and the program contains detailed information about them. Also, Merge Cube offers a possibility to play mobile games and listen to music.  Virtual reality in chemistry education Chemistry lessons in VR is one of the current projects of our company. VR Chemistry Lessons App is a gamified educational program. This app has its own learning plan and a score table with the results of every finished lesson. The interactive virtual environment looks like a classroom with a blackboard, screen for presentations, and the Mendeleev’s  table the student mostly works with. VR Chemistry Lessons App is exclusively designed for Oculus Quest 2. The way VR is changing education Learning school subjects with XR can make students engaged and motivated. When a student is in the virtual or augmented reality, they are capable of learning and understanding school subjects better and faster, thanks to the prevalence of gamified visual content.

Nowadays, a big number of hospitals and rehabilitation centers are already applying virtual reality as the way to provide patients’ recovery. It helps to improve recovery rates, gives patients more motivation, and creates controlled and safe space during the practice. In this blog post, we will tell you more about interesting solutions in virtual reality training, their advantages, and fields where this kind of training is applied. Fields where VR physical recovery is applied Generally, VR technology is created for patients, who are recovering after stroke and serious injuries. The ones who suffer from chronic pains and ones who get through chemotherapy get their own VR treatment too. VR training for stroke survivors are designed to develop self-care habits and improve the control of disease consequences. For patients with chronic pain, VR is a coping mechanism, which helps to distract a person’s attention from the pain and slowly overcome discomfort, using immersion in a virtual adventure. Patients who are on the mend after wounds and injuries have their own VR therapy not only to reduce the pain, but for full or partial resumption of wounded muscle or limb’s capacity. VR training is also applied for cancer patients who get through chemotherapy. Passing games in virtual reality helps to improve memory, common well-being, and distracts from painful discomfort. VR therapy serves as a relieving factor which diverts from chemotherapy side effects such as vertigo, fatigue, vomiting, general weakness, etc. VR industry advantages in patients’ recovery As a supplement to a traditional offline training program, VR therapy has a lot of advantages, including: increasing brain’s work and its cooperation with limbs with the help of special head equipment during the therapy; chronic pain relief — after VR therapy, chronic pain level in patients was proven to decrease by 33%; due to the gaming format and immersion effect of virtual reality, patients become more motivated during the practice; controlled and safe environment of the training; improving patients’ recovery rates, compared to traditional offline therapy — according to the Recovery company statistics, patients improve their motorics during VR exercises by 20% more than during offline therapy. Also, patients with motor impairment recover by 15% faster after VR training; instant and detailed feedback, which is shown up after passing game level in the shape of a tournament table. VR games are a convenient way to monitor a patient’s progress. The results of every game are automatically recorded in the database, which significantly facilitates patient’s health condition tracking. Rehabilitation apps for stroke survivors Many great companies have developed different VR programs specifically for patients who recover from stroke and injuries and work at improving their own bodies’ motorics. MindMotion Go by MindMaze is already used by more than 3000 patients in 90 rehabilitation centers. This program is intuitive, adaptive, and has 17 types of exercises for arms, legs, head and back muscles, etc. Every exercise is made as a 3D arcade, which makes monotonous training more interesting. Also, patients can use MindMotion Go at home. They can make their own exercise program, have unlimited time for training, and periodic video conferences with doctors. Recovery App develops a bunch of physiotherapy and chronic pain relief apps. Specialists have designed a VR therapy for those who suffer from complex regional pain syndrome, chronic and phantom limb pain. These apps are made for restoration of sensitivity, distraction from pain, and breaking the pattern of constant pain and injury fear. Also, the company has announced programs for pain relief and increasing body movement control. RealSystem also offers a gamified VR rehabilitation. For example, in Happy Valley patients help penguins to harvest, go fishing, build houses and do other tasks, as well as make the sun rise in their village. The main target of this program is to restore physical and cognitive habits. Another program, Music in Motion makes patients develop upper body muscles by rhythmical movements, accompanied by music in a candy land, small coast town, and other locations. All RealSystem programs are available as free demos.   Time after time, VR technology proved its efficiency at recovering patients with diseases of the musculoskeletal system. These technologies do not just fasten the recovery, but serve as a good addition to traditional offline exercises. Also, VR technologies enable patients to determine the training schedule and adjust the complexity level of exercises.

We are developing a virtual reality graffiti drawing application for our client. To make the drawing process as realistic and convenient as possible, we have implemented several features, including: The ability to shake the can with realistic sound Visibility of spraying a cloud of paint Dependence of the line thickness on the position of the can Realistic texture filling with paint
