In which it is about the latest beta version of MIUI 10, Xiaomi has added a new feature to the flagship Xiaomi Mi 9, it is about 3D gestures , also known as “3D Air Gestures” . The premise of the function is simple, draw a letter in the air using your smartphone to launch an application corresponding to the drawn letter.  

A Xiaomi employee shared a video on  weibo  to demonstrate how this feature works, the video has been re- uploaded  to  YouTube for our convenience:  

3D Air Gestures for the Xiaomi Mi 9 : The Xiaomi Mi 9 receives 3D gestures in the latest MIUI 10 beta

In the video you can see how the user draws C to launch the Mi 9 camera application , as well as a W to open  TikTok  and a Z to start a different app. We’re not completely sure  of  whether you can choose the applications to be launched with gestures, but there are no technical reasons not possible. In turn, also we understand that makes this more practical method than simply opening  the s  applications  from the home screen. 

This feature probably uses a combination of data provided by the ACCELER it or subway and gyroscope to recognize specific gestures, but really only can assume, since developers have not detailed the exact operation of this feature . 

Returning to the main topic, 3D gestures will only be available for the Xiaomi Mi 9 momentarily . In addition, it is important to note that this is literally the latest MIUI 10 beta, since Xiaomi communicated its plans to end the MIUI global beta program this month . This is due to the fact that the company prefers to focus its efforts on stable versions and the lack of feedback from global beta participants, among other reasons.  

This implies that it will be a considerable time before we see the 3D gestures for the Xiaomi Mi 9 outside of China, so we will have to be patient for now.
