Tom's Guide to smart glasses: 13 terms you need to know

Smart glasses are becoming more common, with brands like Meta and Samsung releasing their own versions. These devices fall into several categories, each using different terms to describe their capabilities. To help you understand these devices, we'll focus on three core concepts: augmented reality (AR), mixed reality (MR), and extended reality (XR).

Augmented reality (AR) involves overlaying digital information onto the real world. This can be done using smartphones or specialized glasses, allowing users to interact with virtual elements in their environment. Companies like Meta and Snap have released AR glasses, such as the Meta Ray-Bans and Snap Spectacles, respectively. These devices use various input methods, such as voice commands, gestures, or touch, to enhance the user experience.

Mixed reality (MR) is a blend between AR and VR. MR devices like Pokémon GO allow users to see digital objects in the real world, creating an immersive experience that combines both environments. MR glasses, such as those offered by Viture, often utilize additional sensory inputs like smart rings or watches to create more interactive experiences.

Extended reality (XR) is an umbrella term that encompasses all types of immersive technology, including VR, MR, and AR. Manufacturers may use this term interchangeably with one of these three categories, which can lead to confusion when choosing a smart glass device. For instance, Viture labels its display glasses as XR, while Xreal uses the same term for its Project Aura glasses. Despite these differences, the underlying technology and functionality remain distinct.
