Xiaomi, a leading consumer electronics and smart manufacturing company in China, announced on February 27 its new Wireless AR Glass Discovery Edition at the Mobile World Congress 2023 (MWC 2023). This is Xiaomi‘s first set of wireless AR glasses to utilize distributed computing, offering a retina-level adaptive display that adjusts to the lighting environment.
Instead of relying on a wired connection to a host computing device, Xiaomi Wireless AR Glass Discovery Edition is weighs just 126g and adopts Xiaomi-developed high-speed interconnection buses to achieve a seamless data connection from smartphone to AR glasses. Built on the Snapdragon XR2 Gen 1 Platform and featuring Xiaomi‘s proprietary low-latency communication link, these Snapdragon Spaces XR Developer Platform-supported glasses offer a wireless latency of as low as 3ms1 between the smartphone device to the glasses, and a wireless connection with full link latency as low as 50ms2.
Xiaomi Wireless AR Glasses are amongst the industry’s first to achieve a “retina-level” display. As with other high-end display concepts, there exists a “critical value” quality threshold for AR glasses. When angular resolution or PPD (pixels per degree) approaches 60, the human eye cannot distinguish granularity. The PPD of the Xiaomi Wireless AR Glasses is 58, which is an industry-leading spec closest to meeting this level of quality.
Leveraging a free-form optical module that comprises a pair of MicroOLED screens, the glasses also feature free-form light-guiding prisms to achieve a crystal clear picture display. These free-form prisms are capable of performing complex light refraction at a limited volume. The content displayed on the screen is reflected by three surfaces within the light-guiding prisms, resulting in a final presentation in front of the user’s eyes.
The AR glasses are also equipped with electrochromic lenses that can adapt to different lighting conditions. These lenses enable a blackout mode that offers an immersive experience when viewing content, while the transparent mode produces a more vivid AR experience that blends reality and virtual elements.
The glasses feature an innovative self-researched micro gesture interaction that enables one-handed, highly-precise pure gesture interaction. It enables users to perform daily app usage operations such as selecting and opening apps, swiping through pages, and exiting apps to return to the start page, all without using a smartphone for controls.
The device supports a variety of large-screen applications available throughout the ecosystem, enabled by Mi Share’s application streaming capability. Popular applications such as TikTok and YouTube can optimize their display area usage of the glasses, essentially turning them into a portable large screen. Additionally, the AR capability allows users to place familiar apps anywhere in the viewing space and adjust their interface size via spatial gestures, thus enhancing the efficiency and overall experience of information access.
