Smart Glasses Explained: AR, MR, XR & More

Smart glasses are expanding into various forms, including AI, AR, MR, and XR devices. Manufacturers often use terms like spatial computing, IPD, and DoF, which can be perplexing. This guide simplifies these concepts for better understanding.

Augmented reality overlays digital information onto the real world, visible through smartphone apps or devices like Snap Spectacles. Mixed reality blends real and digital objects, exemplified by games like Pokémon GO. Extended Reality (XR) serves as an umbrella term for AR, MR, and VR, often implying deeper integration with wearable tech.

Smart glasses fall into categories like AI Audio Glasses, AI Glasses with Display, Virtual Screen Glasses, and Wired XR Glasses. AI glasses, such as Meta's Ray-Bans, offer audio or display features for navigation and communication. Display glasses show digital overlays on lenses, while virtual screen glasses act as wearable monitors. Wired XR glasses, like Xreal's Project Aura, integrate advanced chips for more powerful experiences.

Design elements like battery life, electrochromatic film for tint control, and Interpupillary Distance (IPD) are important considerations. Key capabilities include Field of View (FOV), which determines the visible virtual screen size, and Degrees of Freedom (DoF), tracking device movements for anchored or immersive digital experiences.
