The gear is driven by the motor to rotate, and the gear drives the rack to move, so that the display screen 2 is driven to rotate relative to the body 1.
In some embodiments of the present application, the number of the rotation adjusting mechanisms 4 is multiple, and the multiple rotation adjusting mechanisms 4 are distributed in a central symmetry manner with respect to the rotation axis of the display screen 2. In this way, the rotation of the display screen 2 can be made smoother. For example, the number of the rotation adjusting mechanisms 4 is 2, and 2 rotation adjusting mechanisms 4 are distributed on two opposite sides of the display screen 2. For another example, the number of the rotation adjustment mechanisms 4 is 3, and the 3 rotation adjustment mechanisms 4 are distributed at an angle interval of 120 ° with respect to the rotation center of the display screen 2.

The guide rail 51 is provided with a first guide groove in which the balls 52 are disposed, and the back surface of the display screen 2 is in rolling contact with the balls 52. When the display screen 2 is rotated, the display screen 2 and the rollerball 52 roll relative to each other. The guide rail 51 and the balls 52 can serve as the support structure to support the display screen 2, and can reduce the contact area between the display screen 2 and the body 1, thereby reducing the friction force generated when the display screen 2 and the body 1 rotate relatively.

The visual direction of the user relative to the display screen 2 can be manually input to the electronic equipment by the user, and the facial image information of the user can be automatically collected through the camera 3 to be determined. The visual direction of the user relative to the display screen 2 has a determined corresponding relationship with the deflection angle of the user's face or target features on the face relative to the display screen 2, which has a determined corresponding relationship with the target deflection angle of the display screen 2 relative to the body 1.
When the deflection angle of the target feature relative to the display screen 2 is determined to be within a set range, judging that the visual direction of the user relative to the display screen 2 is the direction of the front-view display screen 2; otherwise, it is determined that the user has a deviation with respect to the viewing direction of the display screen 2. At this time, the rotation adjusting mechanism is controlled to drive the display screen 2 to deflect a target deflection angle relative to the body 1, and the angle compensation of the position of the display screen 2 relative to the body 1 is completed. The orientation of the human-computer interface on the display screen 2 is consistent with the visual direction of the user, so that the user can look at the display screen 2, and the stability of watching the display screen 2 in a motion state is improved.

s600, recording the target deflection angle and generating the historical use habit information of the user.
The step S300 of controlling the rotation adjusting mechanism to drive the display screen to deflect the target deflection angle relative to the body includes:
step S301, controlling the rotation adjusting mechanism to drive the display screen to deflect the target deflection angle relative to the body according to the historical use habit information.
Specifically, when the user views the display screen 2 several times, or views the display screen 2 in a specific scene mode (such as a running scene mode), the visual direction of the user relative to the display screen 2 is acquired, and the visual direction is recorded; or after determining the target deflection angle according to the visual direction, recording the target deflection angle. Historical usage habit information of the user is generated based on the record. When a user watches the display screen 2 in the specific scene mode, directly reading the visual direction in the historical use habit information, and determining a target deflection angle according to the visual direction; or directly reading the target deflection angle in the usage habit information. In this way, the anti-shake angle of the display screen 2 can be optimized.
Wherein, the determining the target deflection angle of the display screen 2 relative to the body 1 according to the historical usage habit information in the step S500 includes:
s510, determining the orientation of the user relative to the display screen 2 according to the facial image information.
S520, determining the target deflection angle of the display screen 2 relative to the body 1 according to the direction of the user relative to the display screen 2 and the historical use habit information.
In particular, the orientation of the user relative to the display screen 2 may be determined by a preliminary analysis of the facial image information. If the target feature is in the set range, the visual direction of the user relative to the display screen 2 is considered as the direction of the front-view display screen 2; otherwise, the target feature is judged to have an offset relative to the display screen 2. When the user watches the display screen 2 in the specific scene mode next time or again, if the direction of the user relative to the display screen 2 is determined to be consistent with the historical use habit according to the facial image information, the visual direction in the historical use habit information is directly read, and the target deflection angle is determined according to the visual direction; or directly reading the target deflection angle in the usage habit information. Otherwise, the target deflection angle of the display screen 2 relative to the body 1 is determined again according to the newly acquired facial image information.
For example, the electronic device is a watch, and when the user is usually used to wear the watch on the left hand, the user will use the habit that the visual direction is deviated to the left relative to the display screen 2. If the direction of the target feature relative to the display screen 2 is determined to be left according to the facial image information, the visual direction of the user relative to the display screen 2 is directly obtained from the historical use habit information. If the user wears the watch with the right hand instead, and the direction of the user relative to the display screen 2 is determined to be right according to the facial image information, the visual direction and the target deflection angle of the user relative to the display screen 2 are determined again according to the newly acquired facial image information, and the new visual direction or the target deflection angle is recorded.
In the control method provided by the present application, in the step S100, acquiring the visual direction of the user relative to the display screen 2 includes:
the method comprises the steps of obtaining facial image information of a user, and determining the visual direction of the user relative to a display screen 2 according to the facial image information.
Specifically, the facial image information of the user can be collected by a camera 3 on the electronic device as in fig. 1. Processing the collected face image information through an image processing technology to generate a target picture; then, filtering the target picture, and extracting target features, such as human eyes or the central position viewed by the human eyes; the deflection angle of the target feature relative to the display screen 2 is calculated in combination with a correlation algorithm. This calculation is prior art and is not specifically described herein. The user's visual direction relative to the display screen 2 is then determined from the angle of deflection of the target feature relative to the display screen 2.
