During the Mobile World Congress that is being held this week in Barcelona, there are many technology firms that decide to show their great innovations, often as a concept with no intention of going on sale.
That is the case of the lenses that Xiaomi has decided to show at the fair, Xiaomi Wireless AR Smart Glass Discovery Edition, the company's first wireless augmented reality glasses that use distributed computing, offering a retina-level adaptive screen that adjusts to ambient lighting.
The idea of this device is that it becomes an extension of the mobile phone, thus improving its connectivity with the smartphone. As the Chinese brand explains, this device adopts high-speed interconnection buses developed by Xiaomi to achieve a high-speed data connection from the smartphone to the glasses.
Likewise, they have been developed on the Snapdragon® XR2 Gen 1 platform and incorporate Xiaomi's patented low latency communication link. Supported by the Snapdragon Spaces XR developer platform, they offer wireless latency as low as 3ms between smartphone and headset, and a wireless connection with a full link latency as low as 50ms that is comparable to wired solutions.
In addition, they boast of their great lightness, weighing only 126 grams.
To improve the display of content on the lenses, Xiaomi engineers have focused on the importance of the quality of virtual images. That is why they claim to launch the first "retina level" glasses in the sector.
And they explain: As with high-end visualization concepts, there is a quality threshold of "critical value" for augmented reality glasses. When the angular resolution or PPD (pixels per degree) approaches 60, the human eye cannot distinguish the granularity. The PPD of Xiaomi Wireless AR Glasses is 58, which is the closest the industry comes to meeting this quality specification.
Another point that has been improved is the control through gestures to achieve a more natural way of interacting.
Xiaomi uses the user's finger joints as the gesture recognition area for Xiaomi's wireless augmented reality glasses.
For example, sliding the thumb over the index finger is used to enter and exit applications, and in the future, Xiaomi hopes to be able to perform swipe and tap operations by randomly moving the thumb in the palm of the hand.
Using these microgestures, users can perform operations such as selecting and opening apps, turning pages, and exiting apps to return to the home page. All this without the need to use a smartphone.
