The Xiaomi Wireless AR Glass Discovery Edition is an augmented reality glasses prototype unveiled by Xiaomi at Mobile World Congress (MWC) 2023. Representing Xiaomi's most advanced AR glasses concept, the Discovery Edition features true wireless operation with the paired Xiaomi 13 smartphone, achieving just 3ms wireless latency between phone and glasses (50ms full link latency—comparable to wired solutions). The glasses are powered by the Qualcomm Snapdragon XR2 Gen 1 chipset and feature dual Micro-OLED displays with up to 1,200 nits brightness and an industry-leading 58 pixels per degree (PPD)—approaching "retina-level" visual quality. The free-form optical module uses light-guiding prisms for clear AR overlay, with electrochromic lenses that can turn opaque for immersive viewing. Weighing 126 grams thanks to a magnesium-lithium alloy and carbon fiber construction, the glasses include three camera modules for environment mapping and support hand tracking gestures for controller-free interaction. The Discovery Edition is compatible with Qualcomm Snapdragon Spaces, OpenXR, and Microsoft MRTK development frameworks. As of 2024, the device remains a prototype with no announced commercial release date; notably, prototype units reportedly have limited battery life of less than 30 minutes.
