Evaluation | Special for cycling, Li Weike’s Meta Lens S1 AR glasses experience

Wen/VR gyro Wanli Li Weike is the virtual IP image launched by Hangzhou Li Weike Technology Co., Ltd.

last year.

This IP has more than 500000 fans in just two months after its launch, and now its number of Tiktok fans has exceeded 1.24 million.

Because of its great success in virtual IP, everyone once thought that Li Wei was a digital human company.

It was not until October this year, when Li Weike released his first AR glasses, that he realized that the company did not seem so simple.

At the new product launch in October, Li Weike launched two products – MetaLensS1 and MetaLensS1Pro.

The prices of these two products in Li Weike’s official flagship store were 3999 yuan and 4999 yuan.

Recently, Gyro Jun received MetaLensS1 and had a long experience.

What is the experience of MetaLensS1, which uses MicroLED screen and focuses on outdoor cycling scenarios? Image source: VR gyro MicroLED+diffractive optical waveguide, supporting eSIM, MetaLensS1 glasses specially made for outdoor cycling scenes adopt color contrast design, the glasses frame is white, the lenses are silver, and the lenses can be removed and replaced.

Its appearance is avant-garde and bold.

When you wear it these days, you feel that your head turning rate is much higher.

If we compare some split AR eyewear products, we can find that its “three dimensions” are a circle larger than other products, and the measured weight of the eyewear body (including lenses and nose rest) reaches 94g.

However, I didn’t feel too much weight anxiety when I actually wore it.

The weight of the mirror legs and the frame is relatively balanced, and it is equipped with a non sensory nose support, so I won’t feel heavy when I wore it.

Source: Li Weike’s team of VR Gyro said that AR glasses should avoid homogeneous competition with VR technology, and must go outside to give play to the real advantages of AR technology.

If you want to go outside, the display brightness has become the first problem faced by the product.

Among many AR eyewear products that Top Gun has experienced in the past, most of them have low brightness and are not friendly for outdoor use.

Source: Li Weike and MetaLensS1 adopt the optical scheme of MicroLED+binocular diffractive optical waveguide.

MicroLED has a series of advantages such as high brightness, high contrast, long life, excellent volume control, etc.

It is one of the ideal display technologies for AR glasses in the future.

MetaLensS1’s opto mechanical supplier is JBD.

From the parameters, its opto mechanical volume is only 0.5cm ³, The weight is 0.6g, and the highest average brightness reaches 1150 nits.

However, its screen can only display a single green screen, which is not a suitable choice for some movie lovers.

However, the focus of this glasses is not on the viewing scene.

Image source: In other aspects of VR gyro, MetaLensS1 also introduced the “single machine binocular” technology: that is, using an optical engine to achieve binocular display.

The single beam is separated into two beams by a beam splitter prism, which are respectively displayed on the left and right sides to achieve binocular balanced display.

“Single machine and double eyes” are rarely used in the industry.

The advantage of the scheme is that only one optical machine is used, thus saving costs; In addition, since the light coupled by the optical machine will have many branches, the “single machine binocular” will distribute two branches to the left eye and the right eye, improving the utilization of light and reducing the energy consumption of glasses.

Finally, because the left and right eyes of the glasses use a whole piece of glass, the parallelism of the waveguide plates on both sides can be guaranteed, so it is more conducive to image combining.

However, it is not without shortcomings.

The disadvantage is that the images displayed on both sides are identical, and it is impossible to achieve binocular differential display, so it is impossible to present 3D effects; In addition, the optical machine needs to be placed at the bridge of the nose, which makes the glasses need to have a very thick beam.

If you want to build the OPPOAirGlass2 type lightweight glasses, this scheme is not applicable.

However, this point is not too offensive when it is put on MetaLensS1, because this kind of cycling glasses has a beam.

The upper part is ordinary cycling glasses, and the lower part is MetaLensS1.

Source: In terms of network product form, MetaLensS1 adopts an integrated design, equipped with Snapdragon 4100 processor, and 1GBRAM+8GBROM.

Glasses can complete motion recording, music listening, navigation, photography and other operations without relying on mobile phones and other devices.

The battery capacity of the glasses is 300mAh, which can provide more than two hours of endurance in normal use.

However, if multiple functions, such as navigation+music playback, are enabled at the same time, the actual endurance of the gyroscope is about one hour and twenty minutes in a continuous use environment.

In terms of network, in addition to supporting Bluetooth, WiFi, GPS, Beidou and other protocols, it also introduces support for the eSIM network.

Currently, an order will give free traffic for one year.

In other aspects, MetaLensS1 is equipped with an 8 megapixel camera, which supports photography and video recording, but does not support SLAM and gesture recognition.

MetaLensS1 parameter table, MetaLensS1Pro additionally supports the heart rate detection function.

Image source: VR gyro, in addition to the eyewear, its charging chamber is also a highlight.

Its shape is similar to the space capsule.

Through the front transparent panel, you can vaguely see the eyewear body, which has a sense of science and technology.

It is also a very good decoration to put on the desktop.

Its battery capacity is 2500mAh, and it is equipped with indicator light for users to check the charging condition of the glasses box and glasses.

The charging box can charge the glasses 7-8 times, which is very convenient for outdoor carrying..
