AR/VR Introductory Guide: Exploring the Infinite Possibilities of Augmented and Virtual Reality from Education to Healthcare
Augmented Reality (AR) and Virtual Reality (VR) technologies are rapidly changing the way we interact with the world. From immersive learning experiences to revolutionizing medical surgery procedures, AR/VR is demonstrating tremendous potential in various fields. This guide aims to provide beginners with a comprehensive introduction to AR/VR, introducing its basic concepts, application areas, and development trends.
What are AR and VR?
- Augmented Reality (AR): AR overlays computer-generated images onto the real world, enhancing the user's perception of reality. Imagine viewing your surroundings through your phone's camera and seeing furniture models placed in the room on the screen. This is one application of AR.
- Virtual Reality (VR): VR replaces the real world with a completely immersive digital environment, making users feel like they are there. Users typically need to wear VR headsets to experience VR, viewing and interacting with the virtual world through the headset.
In simple terms, AR augments reality, and VR creates reality.
Application Areas of AR/VR
The application range of AR/VR is very wide, and here are some main areas:
- Education:
- Immersive Learning Experiences: AR/VR can create interactive learning environments. For example, students can use VR to explore the ancient Egyptian pyramids or view three-dimensional models of human organs through AR. For example, PM Shri JNV Kolasib school in Mizoram, India is using AR/VR to provide immersive learning experiences for students in grades VI to XII (@@JnvKolasib).
- Skills Training: AR/VR can simulate various real-world scenarios to help students and professionals improve their skills. For example, medical students can use VR to simulate surgical procedures, or engineers can use AR to learn how to repair complex equipment.
- Healthcare:
- Surgical Navigation: AR can provide real-time guidance for surgeons, improving surgical precision. For example, Augmedics' AR spinal surgery navigation technology has been acquired by VB Spine (@@NweonXR).
- Rehabilitation Therapy: VR can provide rehabilitation training for patients, such as helping stroke patients recover motor function.
- Psychological Therapy: VR can be used to treat psychological disorders such as anxiety and phobias by simulating scenarios that patients fear in a virtual environment, helping them gradually overcome their fears.
- Retail:
- Virtual Try-On: AR can allow customers to virtually try on clothes, shoes, and glasses at home, improving the shopping experience.
- Augmented Reality Menus: Research from Washington State University shows that AR menus can increase consumers' willingness to spend (@@NweonXR).
- Product Display: AR can display products in three dimensions in front of customers, allowing them to understand the products more comprehensively.
- Games and Entertainment:
- Immersive Gaming Experience: VR can provide players with an unprecedented immersive gaming experience, making them feel like they are in the game world.
- Virtual Tourism: VR allows users to experience scenic spots around the world without leaving home.
- Industry:
- Remote Collaboration: AR can allow engineers in different locations to collaborate and solve problems together.
- Equipment Maintenance: AR can provide technical personnel with equipment maintenance guidance, improving work efficiency.
- Real Estate:
- Virtual House Viewing: VR allows potential buyers to virtually view houses at any time and any place, saving time and effort.
- Interior Design: AR allows users to virtually place furniture in their homes and preview the decoration effect.

The event hosted by SwiftXR x GDGoC UNILAG provided a live demonstration of AR/VR immersive workflows (@@swiftxr_io). jujuunjun110 mentioned using WebGL to create visual effects, which also highlights the importance of learning related technologies (@@jujunjun110). 4. Learn Programming Languages: * C#: The main programming language for Unity. * C++: The main programming language for Unreal Engine. * JavaScript: The main programming language for WebXR. 5. Practice Projects: * Start with Small Projects: For example, create a simple AR application to display a 3D model in the real world, or create a simple VR game. * Participate in Open Source Projects: Participating in open source projects can help you learn from other people's code and improve your skills. * Participate in Competitions and Events: VRフェス is an event to experience VR/AR application development skills (@@demy_vracademy). Participating in competitions and events can help you meet more developers and exchange experiences. PICO is also holding VR experience events (@@NweonXR). 6. Follow Industry Trends: * Read Industry News and Blogs: Understand the latest development trends in AR/VR. * Attend Industry Conferences and Exhibitions: Exchange experiences with other developers and experts.
Some Practical Tips for AR/VR Development* Optimize Performance: AR/VR applications have high performance requirements, requiring optimized code and resources to ensure a smooth experience.
- User Experience First: The design of AR/VR applications should be user-centered, for example, avoiding dizziness and providing clear guidance. Ossy_Oshida mentioned the technology of displaying real space on VR devices, as well as the impact of resolution on the experience (@@Ossy_Oshida).
- Leverage Existing Resources: You can use resources provided by the Unity Asset Store and Unreal Engine Marketplace, such as models, animations, sound effects, etc.
- Continuous Learning: AR/VR technology is developing rapidly, requiring continuous learning of new technologies and tools.
