Virtual reality (VR) has rapidly evolved from its traditional roots to the latest technological advancements in Web XR. This progression has not only expanded the accessibility of immersive experiences but has also revolutionized the way we interact with virtual environments. From the early days of bulky headsets and limited capabilities, to the seamless integration of VR experiences into web browsers, the evolution of VR to Web XR has opened up a world of possibilities for users, creators, and businesses alike. This transformation has not only made VR more user-friendly but has also unlocked new opportunities for industries such as education, gaming, and e-commerce. In the following sections, we will explore the key advancements and innovations that have shaped the evolution from traditional VR to Web XR, and the impact it has had on the virtual reality landscape.
There are two basic types of AR devices: those that use cameras to capture the world and render the WebXR content, and those that use transparent glasses to overlay the rendered image atop the scene. The camera-based AR devices scan the real world through the lens and then overlay the virtual content on top of it, while the transparent glasses-based AR devices render the virtual content directly onto the glasses, so the user can see the real world and the virtual content simultaneously.
Both types of AR devices are capable of presenting VR sessions because they use similar rendering processes to create virtual content. The rendering process for AR involves creating a digital representation of the real world and then overlaying virtual elements onto it, similar to how VR devices create fully immersive virtual environments for the user to navigate.
The main difference between AR and virtual reality is that AR aims to enhance the real world with additional information, while VR aims to create entirely new virtual environments. AR devices use the real world as a base and add virtual elements to it, whereas VR devices completely replace the real world with a virtual one.
Augmented reality (AR) is a technology that superimposes digital information, such as images, videos, or 3D models, onto the real world. Unlike virtual reality (VR), which creates a completely immersive, digital environment, AR enhances the real world with additional digital content. AR devices can be divided into two main types: mobile devices, such as smartphones or tablets, and wearable devices, like AR glasses or headsets.
Babylon.js is a powerful 3D engine that relies on the WebXR standard to support augmented reality experiences in web browsers. WebXR is a set of standards and APIs that enables immersive experiences, including AR and VR, across different devices and browsers. Babylon.js uses WebXR to create AR applications that can be accessed through web browsers, eliminating the need for users to download and install additional software.
In summary, augmented reality enhances the real world with digital information, differs from virtual reality, and leverages WebXR in Babylon.js to create AR experiences accessible through web browsers.
Popular AR applications and devices currently in use include Pokemon Go, IKEA Place, Snapchat, Microsoft HoloLens, and Google Glass. In business, these AR applications are utilized for marketing and advertising, product visualization, and remote assistance.

Web XR and AR intersect in immersive experiences through the blending of augmented reality with virtual reality, creating rich and interactive environments. Web XR enables developers to create immersive experiences that incorporate both AR and VR elements, allowing for seamless integration of digital content into the physical world. The XRSession interface serves as a bridge between the web application and XR devices, enabling developers to interact with XR hardware and advertise XR capabilities to users. This interface allows for the management and control of immersive experiences, as well as the ability to request XR modes such as immersive VR and inline sessions. Immersive VR mode fully immerses the user in a virtual environment, while inline sessions integrate digital content into the real world. These modes offer different levels of immersion and interaction, providing users with versatile experiences. By leveraging WebXR and AR technologies, developers can create dynamic and engaging experiences that push the boundaries of immersive storytelling and interaction.
Web XR blends elements of augmented reality by seamlessly overlaying digital information onto the real world. Unlike virtual reality, which immerses users in a completely different environment, WebXR allows users to interact with their actual surroundings while enhanced digital elements are superimposed onto their view. This creates a mixed reality experience that enhances the user's perception of the real world.
WebXR supports several key features to enhance the augmented reality experience, including hit test, anchors, plane detection, and background remover. Hit test allows digital objects to interact realistically with the physical environment, while anchors enable stable placement of virtual objects in the real world. Plane detection helps identify and augment flat surfaces such as floors and tables, while the background remover eliminates the real-world background, allowing for a more seamless integration of virtual elements.
In summary, WebXR seamlessly integrates augmented reality into the user's real-world environment, enhancing their experience with the overlay of digital information and supporting features like hit test, anchors, plane detection, and background remover.
Web XR platforms are revolutionizing the way we interact with virtual reality by incorporating augmented reality features into their experiences. By merging real-world elements with virtual environments, these platforms are creating innovative and immersive experiences for users. Below are some examples of Web XR platforms that are leading the way in utilizing AR features to enhance their virtual reality experiences.
WebXR is a technology that supports both virtual reality (VR) and augmented reality (AR) experiences, whereas AR is solely focused on overlaying digital content onto the real world. WebXR can be used on a variety of devices including smartphones, tablets, and VR headsets, making it more accessible to a wider range of users.
The specific features and capabilities of WebXR that differentiate it from traditional AR applications include its ability to provide immersive virtual experiences, 3D content integration, and interactive storytelling. WebXR also enables users to create and share virtual environments and experiences, making it a powerful tool for developers and content creators. Moreover, WebXR supports multi-user experiences, allowing users to interact with each other in the same virtual space.
In summary, the key differences between WebXR and AR lie in their support for both virtual and augmented reality experiences, as well as the devices they can be used on. WebXR's unique features and capabilities set it apart from traditional AR applications, making it a versatile and user-friendly platform for immersive experiences.
