XR (Extended Reality)
Definition:
"XR (Extended Reality)" is an umbrella term encompassing all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables. It includes Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR).
Detailed Explanation:
Extended Reality (XR) refers to the spectrum of immersive technologies that blend the physical and digital worlds. XR technologies enable users to interact with digital content in various ways, from fully immersive virtual environments to real-world overlays of digital information. These interactions are facilitated through devices such as VR headsets, AR glasses, and other wearable technologies. XR aims to enhance user experiences by providing more interactive, engaging, and immersive environments.
Key components of XR include:
Virtual Reality (VR):
Creates a fully immersive digital environment that users can explore and interact with, typically using VR headsets.
Augmented Reality (AR):
Overlays digital information and objects onto the real world, enhancing the physical environment with virtual elements, usually viewed through AR glasses or smartphone screens.
Mixed Reality (MR):
Integrates real and virtual environments, allowing users to interact with digital and physical objects simultaneously, often through advanced headsets like the Microsoft HoloLens.
Wearable Devices:
Includes VR headsets, AR glasses, and other wearables that facilitate the interaction between users and the XR environment.
