Abstract

A screen control method is provided. The method includes: detecting, by a mobile terminal, a moving direction of the mobile terminal; detecting, by the mobile terminal, an orientation of a screen of the mobile terminal; receiving, by the mobile terminal, posture information sent by a wearable device, the posture information including a palm orientation of a user of the mobile terminal; sending, by the mobile terminal, a screen recognition instruction to smart glasses when each of the moving direction, the orientation of the screen, and the palm orientation is in a first direction; powering on the screen when screen recognition success information sent by the smart glasses is received; and powering off the screen when each of the moving direction, the orientation of the screen, and the palm orientation is in a second direction, the second direction being different from the first direction.

First claim

What is claimed is:

1 . A screen control method, comprising:
detecting, by a mobile terminal, a moving direction of the mobile terminal; detecting, by the mobile terminal, an orientation of a screen of the mobile terminal; receiving, by the mobile terminal, posture information sent by a wearable device, the posture information including a palm orientation of a user of the mobile terminal; sending, by the mobile terminal, a screen recognition instruction to smart glasses when each of the moving direction, the orientation of the screen, and the palm orientation is in a first direction; powering on the screen when screen recognition success information sent by the smart glasses is received; and powering off the screen when each of the moving direction, the orientation of the screen, and the palm orientation is in a second direction, the second direction being different from the first direction.

2 . The method of claim 1 , wherein the first direction is an upward direction, and the second direction is a downward direction.

3 . The method of claim 1 , wherein detecting the moving direction of the mobile terminal comprises:
acquiring a gravity value detected by a gravity sensor in the mobile terminal; determining that the moving direction of the mobile terminal is the first direction when the gravity value is greater than a first preset threshold; and determining that the moving direction of the mobile terminal is the second direction when the gravity value is less than a second preset threshold, the first preset threshold being greater than the second preset threshold.

4 . The method of claim 1 , wherein detecting the orientation of the screen comprises:
acquiring a Z-axis gravity value detected by a gravity sensor in the mobile terminal; determining that the orientation of the screen is in the first direction when the Z-axis gravity value is a positive value; and determining that the orientation of the screen is in the second direction when the Z-axis gravity value is a negative value.

5 . The method of claim 1 , further comprising:
detecting a state of the screen; performing the powering on the screen when the screen is in an off state; and performing the powering off the screen when the screen is in an on state.

6 . The method of claim 1 , wherein the wearable device includes a smart bracelet or a smart watch.

7 . The method of claim 1 , wherein the first direction is a direction towards a face of the user, and the second direction is a direction away from the face of the user.

8 . The method of claim 1 , wherein the screen recognition success information indicates a detection by the smart glasses that eyeballs of the user are looking at the mobile terminal.

9 . A screen control method, comprising:
initiating, by smart glasses, a screen recognition operation when a screen recognition instruction sent by a mobile terminal is received; acquiring, by the smart glasses, an image within a field of view of the smart glasses; determining, by the smart glasses, whether the image contains a screen of the mobile terminal; generating, by the smart glasses, screen recognition success information when the image contains the screen of the mobile terminal; and sending, by the smart glasses, the screen recognition success information to the mobile terminal.

10 . The screen control method of claim 9 , wherein determining whether the image contains the screen of the mobile terminal comprises:
identifying feature information in the image; acquiring a preset feature template of the screen of the mobile terminal; determining whether the feature information matches the preset feature template; determining that the image contains the screen of the mobile terminal when the feature information matches the preset feature template; and determining that the image does not contain the screen of the mobile terminal when the feature information does not match the preset feature template.

11 . A mobile terminal, comprising:
a processor; and a memory configured to store instructions executable by the processor, wherein the processor is configured to: detect a moving direction of the mobile terminal; detect an orientation of a screen of the mobile terminal; receive posture recognition information sent by a wearable device, the posture information including a palm orientation of a user of the mobile terminal; send a screen recognition instruction to smart glasses when each of the moving direction, the orientation of the screen, and the palm orientation is in a first direction; power on the screen when screen recognition success information sent by the preset smart glasses is received; and power off the screen when each of the moving direction, the orientation of the screen, and the palm orientation is in a second direction, the second preset direction being different from the first preset direction.

12 . The mobile terminal of claim 11 , wherein the first direction is an upward direction, and the second direction is a downward direction.

13 . The mobile terminal of claim 11 , wherein the processor is further configured to:
acquire a gravity value detected by a gravity sensor in the mobile terminal; determine that the moving direction of the mobile terminal is the first direction when the gravity value is greater than a first preset threshold; and determine that the moving direction of the mobile terminal is the second direction when the gravity value is less than a second preset threshold, the first preset threshold being greater than the second preset threshold.

14 . The mobile terminal of claim 11 , wherein the processor is further configured to:
acquire a Z-axis gravity value detected by a gravity sensor in the mobile terminal; determine that the orientation of the screen is in the first direction when the Z-axis gravity value is a positive value; and determine that the orientation of the screen is in the second direction when the Z-axis gravity value is a negative value.

15 . The mobile terminal of claim 11 , wherein the processor is further configured to:
detect a state of the screen; perform the powering on the screen when the screen is in an off state; and perform the powering off the screen when the screen is in an on state.

16 . The mobile terminal of claim 11 , wherein the wearable device includes a smart bracelet or a smart watch.

17 . The mobile terminal of claim 11 , wherein the first direction is a direction towards a face of the user, and the second direction is a direction away from the face of the user.

18 . The mobile terminal of claim 11 , wherein the screen recognition success information indicates a detection by the smart glasses that eyeballs of the user are looking at the mobile terminal.

19 . A smart terminal, comprising:
a processor; and a memory configured to store instructions executable by the processor, wherein the processor is configured to: start a screen recognition operation when a screen recognition instruction sent by a mobile terminal is received; acquire an image within a field of view of the smart terminal; determine whether the image contains a screen of the mobile terminal; generate screen recognition success information when the image contains the screen of the mobile terminal; and send the screen recognition success information to the mobile terminal.

20 . The smart terminal of claim 19 , wherein the processor is further configured to:
identify feature information in the image; acquire a
