About the Course

Get an overview of the content covered in this course.

This course aims to provide a comprehensive introduction to virtual reality (VR)VR is a computer generated 3-D simulation that offers immersion and interactivity. development using WebXR and A-Frame. By the end of the course, you’ll have gained the skills necessary to build VR web experiences.

Throughout the course, we’ll learn about the fundamentals of the WebXR API, including how to set up a scene, create and manipulate spatial environments, and handle user input. We’ll then explore A-Frame, a popular open-source framework for building web-based VR experiences. Using A-Frame, we’ll create and manipulate 3D objects, handle user input, and create interactive experiences. We’ll also learn the core VR development concepts such as lighting, animation, 3D asset management, physics, locomotion, and user interaction.

But before starting our journey, let’s take a moment to reflect on where the internet is today, how it’ll change in the future, and how proficiency with the WebXR development stack could put us in an advantageous position.

Evolution of the internet

The internet has undergone several phases of evolution since its inception. In the early days, the internet was primarily based on a client-server architecture, where a central server would provide static content to its connected clients. Web 1.0 consisted of fetching read-only information from the central servers. Users could only interact by leaving comments or reviews on static web pages. With the growth and increasing popularity of the internet, the shortcomings of this model became evident, especially in terms of scalability and the absence of interactivity.

The second iteration of the internet, Web 2.0, is more participatory. The content is dynamic and generated mainly by the users themselves. It consists of photos, videos, and audio uploaded onto central servers owned by tech/social media giants like Facebook, Twitter, Instagram, WhatsApp, and Google. The users have less or no control over their data becuase they don’t own any of it.

These privacy and data ownership concerns led us to envision Web 3.0: a decentralized internet based on blockchain technology. It’s a more open, transparent, and secure internet, where users have more control over their data and online experiences. Web 3.0 technologies like Ethereum and IPFSInterPlanetary File System enable the development of decentralized applications, smart contracts, and other services that can operate without centralized intermediaries. The Web 3.0 framework also envisions an immersive internet via metaverse technologiesMetaverse technologies include immersive technologies such as augmented reality (AR), virtual reality (VR), and mixed reality (MR), enabling the transition to Web 3.0..

Similarly, the metaverse is an emerging concept of a virtual shared space where users can interact with each other, access information and services, and participate in various activities, from socializing to commerce. The metaverse is a new frontier for the internet, built on the foundations of Web 3.0 technology. It’s expected to impact how we interact and experience the web significantly.

Back in 2007, mobile phones transformed how we go about our lives. The smartphone disrupted the internet and unlocked a new era of possibilities. Today, VR technologies come with a similar promise of abundant opportunities. VR technologies have become some of the key drivers of Web 3.0. Recent advances in computer graphics and networks have further catalyzed humanity’s shift to the metaverse and phenomenally changed how we experience and interact with the internet.

Extended reality (XR)Extended reality (XR) encapsulates the AR, VR, and MR technologies. technologies will be our gateway to Web 3.0. They’ll enable users to access lightweight XR experiences through their web browsers, making XR more accessible to a broader range of people. Overall, WebXR is an important technology that can play a key role in the future of the internet, the metaverse, and Web 3.0.

Why should we learn VR?

We know that VR is great, but why should we invest time in learning about VR development? Here are three strong reasons to prepare for this world of new possibilities:

Creative expression: VR gives us an opportunity to experiment with our ideas. People from all backgrounds, such as education, healthcare, and technology, can harness metaverse technologies to their specific use cases. Moreover, VR development allows developers to create immersive, interactive experiences that can transport users to new worlds, improve their understanding of complex concepts, and more. Learning VR development can enable creators to try new approaches to tackle hard problems in fields as diverse as education, psychology, healthcare, and engineering.

Applications: In the near future, our access to the internet and applications won’t be limited to flat screens. As immersive technology gains popularity, the need to develop and explore the creation of programs and functions for these devices becomes more crucial. From healthcare interventions to cinematic masterpieces, VR has immense potential to revolutionize various industries.

The excitement around these technologies has harnessed great interest in VR development. VR technologies are fundamentally transforming how we approach business, healthcare, gaming, and nearly every aspect of our lives in the foreseeable future. To truly understand the impact of these technologies, we need to learn the skills that help us build this reality.

Market size: According to StatistaStatista. (n.d.). Virtual reality (VR) market size worldwide from 2020 to 2024. Retrieved from https://www.statista.com/statistics/1221522/virtual-reality-market-size-worldwide/, worldwide total market of VR is forecasted at $22 billion by the year 2025. The founder of Facebook (now Meta), Mark Zuckerberg, famously said in 2017 that he wanted a billion people using Oculus headsets. After Meta’s deep interest in AR/VR headsets, other consumer tech players, including Google, HTC, Samsung, and Sony, have joined Meta in the race to bring consumer-ready headsets to market. With the boom in VR, developers can use this opportunity to their craftsmanship and earn more.

Overall, XR development is an exciting and rapidly growing field that offers many opportunities for those interested. It offers a challenging, creative, and well-paying career path with a wide range of opportunities to work in different industries.
