On February 27, 2023, Xiaomi officially released the exploration version of Xiaomi wireless AR glasses at the MWC World Mobile Communications Congress (MWC 2023) in 2023. Xiaomi Wireless AR glasses Exploration Edition is the first wireless distributed computing AR glasses product, with retina-level light environment adaptive display experience, easy to connect with mobile phones, support innovative micro-gesture interaction, complete large-screen application ecology, and rich interconnection scenes, attracting many live media to stop and understand.

Ushering in the wireless era with end-to-end latency as low as 50ms

Xiaomi believes that human-centered AR glasses should reduce their sense of existence. This requires not only a very light weight at the end of the glasses, but also no other burden on the user. Although the weight of the existing AR glasses is reduced by external calculation, the degree of freedom of wearing comfort and spatial interaction is affected by having to be wired with the computing device.

Xiaomi wireless AR glasses are the first AR glasses with wireless connection scheme. Thanks to Xiaomi's years of accumulation in cross-device interconnection and communication, Xiaomi will take the lead in developing a high-speed interconnection bus for the connection between mobile phones and AR glasses. Based on Qualcomm Snapdragon XR2 chip, relying on Xiaomi self-developed low delay communication link and Qualcomm Snapdragon Spaces, the communication delay between mobile phone and glasses is lower than 3ms, and the full link delay is as low as 50ms, which is comparable to the cable solution.

Xiaomi wireless AR glasses adopt the lightweight design of the whole machine, including magnesium-lithium alloy, carbon fiber parts, self-developed silicon-oxygen negative electrode battery and a large number of lightweight materials, the whole machine weighs only 126g. At the same time, based on tens of thousands of head data, accurately calibrate the center of gravity, leg spacing, holding angle, nose rest and other details of the glasses, so that users can get a better wearing experience.

‎ retina level display, support electrochromic transparent shading one-click switch

Xiaomi believes that to achieve a perfect blend of the digital world and the real world, it is necessary to let users see virtual objects as clear and bright as physical objects, which requires the device to have a very high display quality.

Xiaomi wireless AR glasses are the first in the industry to achieve "retinal level" display. Similar to the familiar concept of "retinal screen", there is a "threshold" in AR glasses: when the PPD (angular resolution) is close to 60, it is difficult for the human eye to detect graininess. The PPD of Xiaomi wireless AR glasses is 58, which is the closest to the "retina" specification in the industry.

In order to achieve such a clear picture, Xiaomi wireless AR glasses adopt a free-form surface optical module, which is composed of a pair of MicroOLED screens and a free-form surface light guide prism. A free-form surface prism can achieve complex light refraction and reflection in a limited volume. The content displayed on the screen is finally presented in front of the user through the reflection of three surfaces in the light guide prism.

This optical module design allows Xiaomi wireless AR glasses to have extremely low light loss and up to 1200nit brightness. The clear and bright picture provides a solid foundation for AR applications. Xiaomi wireless AR glasses are also equipped with electrochromic lenses to adapt to different light environments. Shading mode can provide immersion experience when watching movies, and transparent mode makes the experience of the combination of virtual and real AR more vivid.

Innovative micro-gesture interaction may be a more natural way of interaction.

Xiaomi wireless AR glasses are also equipped with innovative self-developed micro-gesture interaction. This kind of single-handed, small-scale pure gesture interaction is one of the development directions of human-computer interaction in the future.

Xiaomi uses the knuckle area of the palm as a gesture recognition area. Take the middle joint of the middle finger as the origin of the direction key, the second joint of the index finger as the upper, and then combine with other adjacent areas to form a four-way directional key to realize the basic mobile operation; 12 finger joints are exactly similar to the Chinese nine-key input method, and the thumb can be typed by pressing the thumb in the finger area; sliding the thumb on the index finger represents entering and exiting the application. In the future, Xiaomi also hopes to slide and click on the plane through the random movement of the thumb in the palm.

In the daily process of using an app, pick an app and open it, swipe the page, exit the app and return to the desktop, all of which can be interacted with microgestures on Xiaomi's wireless AR glasses without the need for a mobile phone.

To achieve this function, Xiaomi's wireless AR glasses are equipped with a low-power AON camera, which makes it possible to interact with gestures for a long time. At the same time, Xiaomi wireless AR glasses also provide a traditional interactive way to operate using a mobile phone as a touchpad or handle.

Bring more interconnection and new experience to AR glasses.

As Xiaomi has been deeply involved in the field of cross-device interconnection for many years, it has also brought many new experiences of interconnection on Xiaomi wireless AR glasses.

Based on Xiaomi's application flow ability, Xiaomi wireless AR glasses support a complete large screen application ecology. Common applications such as Weibo, Douyin, bilibili, etc., can make full use of the display area of Xiaomi wireless AR glasses, making Xiaomi wireless AR glasses a portable large screen. With the help of AR ability, users can also put familiar applications in space at will, adjust their interface size through space gestures, and improve the efficiency of information acquisition.

As the world's largest smart home platform, Xiaomi also uses AR to bring a new experience to smart home. Take the common TV screen as an example, using Xiaomi wireless AR glasses, users can "catch" the picture they are playing on TV, and then get up and watch it while walking. Xiaomi also extracts the common operations of smart devices, so that you can operate which device you look at in the AR scene. For example, when users look at the lamp, they can use space gestures to click on the virtual button on the lamp to switch the light on. Xiaomi also realizes the spatial audio experience of the virtual speaker, so that the virtual speaker can be linked with the real environment.

Xiaomi Wireless AR glasses Exploration Edition needs to be used with models such as Xiaomi 13. There is a titanium empty silver version that supports three sizes of nose brackets. Myopic users can use myopic clips. In terms of software ecology, Xiaomi supports Qualcomm Snapdragon Spaces, OpenXR and Microsoft MRTK development framework. Xiaomi expressed the hope to work with developers to accelerate the arrival of the AR era.
