This device, which weighs only 126g does not rely on a wired connection to the host computing device. They are built up of magnesium-lithium alloy, carbon fiber parts, and a self-developed silicon-oxygen anode battery.
They are powered by the Snapdragon Spaces XR Developer Platform having latency as low as 3ms between the smartphone device and the glasses and a wireless connection with full link latency of as little as 50ms, which is comparable to wired solutions.
According to the company the Xiaomi Wireless AR Glass Discovery Edition has been calibrated with precision, taking into account details such as the center of gravity, leg spacing, angle, nose rest, and other factors.
The Xiaomi AR glasses feature a “retina-level” display. When PPD (pixels per degree) or angular resolution hits 60, granularity cannot be distinguished by the human eye. Notably, the PPD of the Xiaomi Wireless AR Glasses is 58. Xiaomi Wireless AR Glass includes free-form light-guiding prisms in addition to a free-form optical module that consists of two MicroOLED displays. These free-form prisms are capable of performing complex light refraction in a limited volume. As stated by the firm, three surfaces inside the light-guiding prisms reflect the content shown on the screen, resulting in a final presentation in front of the user’s eyes. Because these glasses have an optical module design light loss is minimised and clear and bright images are produced with a to-eye brightness of up to 1200nit. It comes incorporated with electrochromic lenses that could change colour depending on different lighting conditions. These lenses offer a transparent mode that creates a more vivid AR experience that blends reality and virtual elements whereas the blackout mode supports an immersive experience when viewing content.
Moreover, Xiaomi Wireless AR Glass has an innovative self-researched micro gesture interaction that enables one-handed, highly-precise pure gesture interaction.
For the Xiaomi Wireless AR Glasses, Xiaomi uses the joints in the user’s inner fingers as a gesture recognition area. “The directional is oriented from the second joint of the middle finger, with the second joint of the index finger representing the upward direction. When combined with the surrounding areas, this forms a four-way directional key for basic movement operations. In addition, the 12 knuckles function similarly to the Chinese nine-key input method, allowing for text input through thumb tapping in the finger area. The thumb sliding on the index finger is used to enter and exit applications. Looking forward, Xiaomi hopes to enable sliding and tapping operations through the random movement of the thumb in the palm.”
