Immersive Web technologies like WebXR allow developers to build augmented and virtual reality experiences that can be accessed through web browsers on various devices. This expands accessibility of XR beyond specialized headsets to a wide range of phones, tablets and computers. WebXR uses web standards and APIs to integrate with sensors, displays and inputs, enabling cross-device experiences. As support grows across browsers and devices, the web has the potential to become a leading platform for immersive content and applications.
