Method for controlling screen of mobile terminal, and apparatus
A method includes obtaining, by a mobile terminal, a motion parameter of the mobile terminal, determining whether the motion parameter meets a pick-up parameter threshold or a put-down parameter threshold, determining that the mobile terminal is picked up when the motion parameter meets the pick-up parameter threshold, obtaining a sight line parameter of a user, and switching the screen to an on state when a visual center of the user is on a screen of the mobile terminal and the screen is in an off state.
1. A method for controlling a screen of a mobile terminal, comprising:
obtaining a motion parameter of the mobile terminal when the screen is in an off state;
determining that the motion parameter indicates that the mobile terminal is picked up when the screen is in the off state;
obtaining a sight line parameter of a user after the mobile terminal is picked up and when the screen is in the off state;
determining that the sight line parameter of the user indicates that a visual center of the user is on the screen by obtaining the sight line parameter of the user within a preset time after the mobile terminal is picked up; and
switching the screen from the off state to an on state when the visual center of the user is on the screen within the preset time after the mobile terminal is picked up.
2. The method of claim 1 , wherein the motion parameter corresponds to a speed of the mobile terminal.
3. The method of claim 2 , further comprising:
comparing the speed of the mobile terminal to a threshold; and
determining that the mobile terminal is picked up when the speed of the mobile terminal exceeds the threshold.
4. The method of claim 1 , wherein the motion parameter corresponds to a moving height of the mobile terminal.
5. The method of claim 4 , further comprising:
comparing the moving height of the mobile terminal to a threshold; and
determining that the mobile terminal is picked up when the moving height of the mobile terminal exceeds the threshold.
6. The method of claim 1 , wherein the motion parameter corresponds to an angle of the mobile terminal.
7. The method of claim 6 , further comprising:
comparing the angle of the mobile terminal to a threshold; and
determining that the mobile terminal is picked up when the angle exceeds the threshold.
8. The method of claim 6 , wherein the angle of the mobile terminal comprises an angle between a plane of the screen and a plane of eyes of the user.
9. A mobile terminal, comprising:
a processor;
a screen coupled to the processor; and
a memory coupled to the processor, wherein the memory is configured to store instructions that, when executed by the processor, cause the mobile terminal to:
detect that the mobile terminal is picked up when the screen is in an off state;
detect that a visual center of a user is on the screen when the screen is in the off state by obtaining a sight line parameter of the user within a preset time after the mobile terminal is picked up; and
switch the screen from the off state to an on state when the visual center of the user is on the screen within the preset time after the mobile terminal is picked up.
10. The mobile terminal of claim 9 , further comprising a sensor coupled to the processor and configured to detect a speed of the mobile terminal, wherein the processor is configured to determine that the mobile terminal is picked up when the speed of the mobile terminal exceeds a threshold.
11. The mobile terminal of claim 9 , further comprising a sensor coupled to the processor and configured to detect a moving height of the mobile terminal, wherein the processor is configured to determine that the mobile terminal is picked up when the moving height of the mobile terminal exceeds a threshold.
12. The mobile terminal of claim 9 , further comprising a sensor coupled to the processor and configured to detect an angle of the mobile terminal, wherein the processor is configured to determine that the mobile terminal is picked up when the angle of the mobile terminal exceeds a threshold.
13. The mobile terminal of claim 12 , wherein the angle of the mobile terminal comprises an angle between a plane of the screen and a plane of eyes of the user.
14. The mobile terminal of claim 9 , further comprising a camera coupled to the processor, wherein the camera is configured to obtain an image of the user, and wherein the processor is configured to analyze the image of the user to determine the visual center of the user.
15. The mobile terminal of claim 14 , wherein the visual center of the user is based on eye tracking of the user.
16. The mobile terminal of claim 14 , wherein the visual center of the user is based on analyzing a facial image of the user.
