Thanks to CTOnews.com netizens Pianke Sao Huang 4100 eyes, modesty clue delivery! CTOnews.com February 27 news, Xiaomi today at the MWC 2023 Mobile World Congress officially released Xiaomi wireless AR glasses exploration version.

In this regard, Xiaomi founder, chairman and CEO Lei Jun said in a post that this is a human-centered AR glasses, with extremely light weight, the first to adopt wireless distributed computing, retina-level light environment adaptive display, connect with the mobile phone at a touch, support innovative micro-gesture interaction, complete large-screen application ecology and rich interconnection scenes and other functions.

Lei Jun said that Xiaomi wireless AR glasses exploration version, is a wireless connection scheme of AR glasses. Xiaomi has successfully developed a high-speed interconnection bus, which is the first to be applied to the connection between mobile phones and AR glasses. Relying on the self-developed low-delay communication link and Qualcomm Snapdragon Spaces, the communication delay between mobile phone and glasses is lower than 3ms, and the whole link delay is as low as 50ms.

When talking about "retinal level" display, Lei Jun said that it is similar to the concept of retinal screen, when the PPD (angular resolution) is close to 60, human eyes can hardly feel the sense of particles. The PPD of Xiaomi wireless AR glasses is 58, which is very close to the "retina" specification.

In terms of software ecology, CTOnews.com learned from Xiaomi officials that Xiaomi Wireless AR glasses Exploration Edition supports Qualcomm Snapdragon Spaces, OpenXR and Microsoft MRTK development framework.

The following is Lei Jun's interpretation of Xiaomi's wireless AR glasses exploration version:

Innovation uses wireless connection, end-to-end delay as low as 50ms a good AR glasses, should be very low sense of presence, do not put a burden on users. Although the existing AR glasses lose weight by handing over the main computing power to external devices, they must be wired to the computing equipment, which greatly affects the comfort of wearing and the degree of freedom of spatial interaction.

And Xiaomi wireless AR glasses exploration version, is a wireless connection scheme of AR glasses. Thanks to our deep accumulation in multi-device interconnection and communication, we successfully developed a high-speed interconnection bus, which was first applied to the connection between mobile phones and AR glasses. Relying on the 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 scheme.

Xiaomi wireless AR glasses exploration version front appearance Xiaomi wireless AR glasses adopts the lightweight design of the whole machine, including magnesium-lithium alloy, carbon fiber parts, self-developed silicon-oxygen negative 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.

Advanced "retina" shows that the digital and the real world blend perfectly in the process of making AR glasses. The biggest problem we encounter is how to make users look at the pictures of the glasses as clearly and brightly as they see the real thing. This is a great challenge to the display quality of the equipment.

So this time, we have achieved a "retinal" display on the glasses, which may be a little confused. Let me briefly explain to you that you may be more familiar with the "retinal screen" of mobile phones and tablets. It refers to the high-resolution screen that exceeds the limit of human eye recognition, and since it is the limit, there will be a critical value. On the other hand, the "retinal level" shows that, similar to the concept of the retinal screen, when the PPD (angular resolution) is close to 60, the human eye can hardly feel the graininess. The PPD of Xiaomi wireless AR glasses is 58, which is very close to the "retina" specification.

Behind the "retina level" display of the optical structure diagram of Xiaomi wireless AR glasses exploration version, we use a free-form surface optical module, which is composed of a pair of MicroOLED screens and free-form surface light guide prisms.

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.

The advantage of this optical module design is that the AR glasses can have extremely low light loss, the maximum brightness can reach 1200nit, and the picture can be seen more clearly and brightly, providing a solid foundation for application.

Xiaomi wireless AR glasses are also equipped with electrochromic lenses, which can adapt to different light environments, shading mode can be more immersed when watching movies, and transparent mode can make the experience of the combination of virtual and real AR more vivid.

Innovative micro-gesture interaction, more natural and more comfortable, how to develop human-computer interaction in the future? We also put forward our own direction, in Xiaomi wireless AR glasses, equipped with innovative self-developed micro-gesture interaction: one-handed, small amplitude, pure gesture, more natural and comfortable to use.

Users can select applications and open them, swipe to browse, return to the desktop and other daily use behavior, micro-gesture interaction can support, do not need to use the mobile phone.

Simply explain the mode of operation, put your fingers horizontally, and the knuckle area you see is the gesture recognition area we set up. We use the middle joint of the middle finger as the origin of the direction key, and then combine with other adjacent regions to form a four-way direction key to achieve the basic movement operation.

In order to achieve the above functions, we have installed a low-power AON camera on Xiaomi's wireless AR glasses, which also makes it possible to interact with gestures for a long time. In addition, we also provide a traditional way of interaction, you can use your phone as a touchpad or remote control.

New experience of connectivity, multi-scene intelligent collaboration based on Xiaomi Miaoxian's application flow ability, Xiaomi wireless AR glasses support a complete large screen application ecology, and applications you are familiar with, such as Weibo, Douyin, bilibili, etc., can make full use of the display area of Xiaomi wireless AR glasses to make them a big screen for you. With the help of AR, you can also put familiar applications in space at will, and adjust the size of the interface through space gestures, isn't it particularly convenient?

As a smart home platform, we also use AR to bring a new experience for smart home. Let me give you an example. You are operating the TV screen. When you put on Xiaomi wireless AR glasses, you can "catch" the picture shown on TV, and then get up and watch it while walking. It's really cool!

We have also extracted the common operations of smart devices. When you are in an AR scene, you can operate which device you want to use (only Mi home control devices are supported). For example, if you look at the lamp, you can turn it off with a single click of the gesture. In addition, you can also put a virtual small love speaker in the space to enjoy the telepresence of the space audio.

The exploration version of Xiaomi wireless AR glasses now supports Xiaomi 13 series models, supporting 3 sizes of nose rest and myopic clips.

In terms of software ecology, we support Qualcomm Snapdragon Spaces, OpenXR and Microsoft MRTK development framework, and we hope to work with more developers to accelerate the arrival of the AR era.

Xiaomi will always be the coolest company in the heart of rice noodles.
