Abstract

A misoperation-preventing method for use in a mobile terminal having a touch screen, includes: monitoring a distance between the mobile terminal and an object in a surrounding environment, after the mobile terminal transitions from a standby state to an active state; determining if the distance satisfies a preset distance condition; and disabling the touch screen if it is determined that the distance satisfies the preset distance condition.

Claims

1. A misoperation-preventing method for use in a mobile terminal having a touch screen, comprising:

monitoring a distance between the mobile terminal and an object in a surrounding environment, after the mobile terminal transitions from a standby state to an active state;

determining if the distance satisfies a preset distance condition; and

disabling the touch screen if it is determined that the distance satisfies the preset distance condition.

2. The method of claim 1, wherein the monitoring comprises:

monitoring the distance between the touch screen of the mobile terminal and a nearest object in front of the touch screen.

3. The method of claim 1, wherein the disabling comprises:

causing the mobile terminal to transition into a screen-off state preset by an operating system of the mobile terminal, and to report a cause for transitioning into the screen-off state for the operating system to judge, on the basis of the cause for transitioning into the screen-off state, whether to implement a control command given by a user not through the touch screen.

4. The method of claim 1, wherein if the mobile terminal determines that the distance does not satisfy the preset distance condition, the method further comprises:

enabling the touch screen of the mobile terminal.

5. The method of claim 4, after the enabling of the touch screen of the mobile terminal, the method further comprising:

determining whether the distance continues to not satisfy the preset distance condition for a preset time period;

stopping monitoring of the distance between the mobile terminal and the object in the surrounding environment, if it is determined that the distance continues to not satisfy the preset distance condition for the preset time period; and

disabling the touch screen, if it is determined that the distance satisfies the preset distance condition before the end of the preset time period.

6. The method of claim 1, wherein the determining comprises determining if the distance is smaller than, or equal to, a preset distance threshold.

7. A non-transitory medium including instructions, executable by a processor in a mobile terminal, for performing a misoperation-preventing method, the method comprising:

monitoring a distance between the mobile terminal and an object in a surrounding environment, after the mobile terminal transitions from a standby state to an active state;

determining if the distance satisfies a preset distance condition; and

disabling the touch screen if it is determined that the distance satisfies the preset distance condition.

8. The non-transitory medium of claim 7, wherein the monitoring comprises:

monitoring the distance between the touch screen of the mobile terminal and a nearest object in front of the touch screen.

9. The non-transitory medium of claim 7, wherein the disabling comprises:

causing the mobile terminal to transition into a screen-off state preset by an operating system of the mobile terminal, and to report a cause for transitioning into the screen-off state for the operating system to judge, on the basis of the cause for transitioning into the screen-off state, whether to implement a control command given by the user not through the touch screen.

10. The non-transitory medium of claim 7, wherein if it is determined that the distance does not satisfy the preset distance condition, the method further comprises:

enabling the touch screen of the mobile terminal.

11. The non-transitory medium of claim 10, after the enabling of the touch screen of the mobile terminal, the method further comprising:

determining whether the distance continues to not satisfy the preset distance condition for a preset time period;

stopping monitoring of the distance between the mobile terminal and the object in the surrounding environment, if it is determined that the distance continues to not satisfy the preset distance condition for the preset time period; and

disabling the touch screen, if it is determined that the distance satisfies the preset distance condition before the end of the preset time period.

12. The non-transitory medium of claim 7, wherein the determining comprises determining if the distance is smaller than, or equal to, a preset distance threshold.

13. A mobile terminal, comprising:

a processor; and

a touch screen coupled to the processor;

wherein the processor is configured to;

monitor a distance between the mobile terminal and an object in a surrounding environment, after the mobile terminal transitions from a standby state to an active state;

determine if the distance satisfies a preset distance condition; and

disable the touch screen if the processor determines that the distance satisfies the preset distance condition.

14. The mobile terminal of claim 13, wherein the processor is further configured to:

monitor the distance between the touch screen of the mobile terminal and a nearest object in front of the touch screen.

15. The mobile terminal of claim 13, wherein the processor is further configured to:

cause the mobile terminal to transition into a screen-off state preset by an operating system of the mobile terminal, and to report a cause for transitioning into the screen-off state for the operating system to judge, on the basis of the cause for transitioning into the screen-off state, whether to implement a control command given by the user not through the touch screen.

16. The mobile terminal of claim 13, wherein if it is determined that the distance does not satisfy the preset distance condition, the processor is further configured to:

enable the touch screen of the mobile terminal.

17. The mobile terminal of claim 16, after the enabling of the touch screen of the mobile terminal, the processor being further configured to:

determine whether the distance continues to not satisfy the preset distance condition for a preset time period;

stop monitoring of the distance between the mobile terminal and the object in the surrounding environment, if it is determined that the distance continues to not satisfy the preset distance condition for the preset time period; and

disable the touch screen, if it is determined that the distance satisfies the preset distance condition before the end of the preset time period.

18. The mobile terminal of claim 13, wherein the processor is further configured to determine if the distance is smaller than, or equal to, a preset distance threshold.
