Chapter 5: Devices, Hardware, and Technical Foundations of XR
Abstract : Extended Reality (XR) is an umbrella term for technologies that merge physical and virtual worlds, including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). The technical foundation relies on specialized hardware for input/output and powerful software and algorithms for processing and managing the immersive experience. Hardware Devices The specific hardware used varies based on the type of XR experience, ranging from existing mobile devices to specialized head-mounted displays. Head-Mounted Displays (HMDs): These are the primary devices for delivering immersive experiences. VR Headsets: Opaque displays that completely replace the user's surroundings with a digital environment (e.g., Meta Quest series, HTC Vive). AR Glasses/Smartglasses: Transparent lenses that overlay digital information onto the real world (e.g., Google Glass, Snap Spectacles). MR Headsets: Advanced se...
