When the first position information and the second position information are both expressed in the form of coordinates, the first rotation angle and the first rotation direction can be determined and obtained according to the relative relationship between the first position information and the second position information and the origin of coordinates.

Optionally, after determining the first rotation direction according to the first position information and the second position information, the terminal may obtain a first preset angle as the first rotation angle (the value range of the first preset angle may be 10 ° -45 °). For example, when the user waves the arm with the wearable device to the left of the user, the terminal can determine that the first rotation direction is the clockwise rotation direction according to the first position information and the second position information of the wearable device before and after the arm waves, and when the current first preset angle value is 15 degrees, the terminal can control the display screen to rotate 15 degrees in the clockwise direction.

Alternatively, the voice command sent by the user may include angle and direction information, and the terminal may obtain the second rotation angle and the second rotation direction by recognizing content information in the voice command. For example, when the user speaks a voice command of "rotate clockwise by 5 °, the second rotation angle acquired by the terminal according to the voice command is 5 °, and the second rotation direction is clockwise.

It should be noted that, when the voice command only includes the direction information, the terminal may use the second preset angle as the second rotation angle.

Optionally, the second preset angle is smaller than the first preset angle, and the second preset angle is smaller and may be a minimum rotation angle of the display screen, and a value range of the second preset angle may be 1 ° to 10 °.

Optionally, the user may also effect issuance of the second control instruction by continuing to maintain the current location of the wearable device. Namely, when the terminal detects that the displacement of the wearable device is between the preset distance ranges within the first preset time, it is determined that the second control instruction is received. Specifically, after the terminal controls the display screen to rotate according to the first rotation direction and the first rotation angle, when the component of the displacement of the wearable device detected within the first preset time length on the display screen rotation plane is within the preset distance range, (the second rotation angle and the second rotation direction can be obtained according to the preset rule, namely the component of the displacement of the wearable device detected within the first preset time length on the display screen rotation plane is 5cm, and the preset distance range is 3-10cm, it is determined that the audio device receives the second control instruction, and the display screen is controlled to rotate according to the second rotation direction and the second rotation angle, wherein the specific information of the second rotation angle and the second rotation direction can be set according to the preset rule.

After the terminal controls the display screen to rotate according to the first rotating direction and the first rotating angle, when the rotating result is not completely rotated to the position expected by the user, the user can send a second control instruction within a first preset time length at the moment, and the display screen is controlled to rotate according to the second rotating direction and the second rotating angle so as to guide the display screen to do small correction rotation and enable the display screen to meet the watching requirement of the user.

In an embodiment, when a second control instruction is detected within a first preset time period, a second rotation angle and a second rotation direction are obtained; and controlling the display screen to rotate according to the second rotating direction and the second rotating angle. Therefore, the accurate fine adjustment of the viewing angle of the display screen of the audio equipment by a user is facilitated.
