6. ActiveTrack Select Box :
   ActiveTrack 3.0 ActiveTrack 3.0 has been optimized for tracking human subjects with
   a head and shoulder model along with face detection using deep learning algorithms. The subject will remain in the center of the camera view by default. The camera view can be adjusted manually. There are three ways to use ActiveTrack 3.0:
   a. Drag a box on the screen in the camera view in DJI Mimo. A green box around the subject indicates ActiveTrack 3.0 is successfully enabled. Tap the X icon on the top corner to stop tracking.
   b. Enable Gesture Control in DJI Mimo and perform a palm or V gesture for one to two seconds when facing the camera. The back camera will detect the nearest head and shoulders and start to track the subject. The front camera will detect the nearest face and start to track the subject.
   
   The differences between head and shoulder tracking and face tracking are that head and shoulder tracking supports 360° tracking while face tracking does not. Also, the detection range of the cameras is different. The detection range between the back camera and the gesture is 0.5 to 4 m, and the distance between the front camera and the gesture is 0.5 to 2 m. Note that ActiveTrack 3.0 may consume more power and cause the temperature of the mobile phone to increase.
