Abstract

A method for controlling a touch device to power on or power off has steps of receiving direction information of the touch device; determining if the touch device is oriented to a direction that is outside or inside a preset viewing angle according to the direction information; detecting a gesture present on the touch device; and performing a power-saving function or a power-on function when detecting the gesture present on the touch device and determining that the direction of the touch device is outside or inside the preset viewing angle. The foregoing technique can replace the power-saving function and the power-on function activated by pressing a physical power button. Accordingly, operational frequency and failure rate of the physical power button can be reduced and an intuitive method for powering on or off the touch device with easy operation can thus be provided.

Claims

1. A method for controlling a touch device to power off performed by the touch device, the method comprising steps of:

receiving direction information of the touch device;

determining if the touch device is oriented to a direction that is out of a preset viewing angle according to the direction information;

detecting a gesture present on the touch device;

and performing a power-saving function when detecting the gesture present on the touch device and determining that the direction of the touch device is out of the preset viewing angle.

2. The method as claimed in claim 1, wherein when the direction of the touch device is determined to be out of the preset viewing angle, an angle included between the direction of the touch device and an X axis corresponding to a horizontal direction of the touch device is greater than the preset viewing angle.

3. The method as claimed in claim 1, wherein when the direction of the touch device is determined to be out of the preset viewing angle, an angle included between the direction of the touch device and a Y axis corresponding to a vertical direction of the touch device is greater than the preset viewing angle.

4. The method as claimed in claim 1, wherein the gesture is selected from one of a multi-touch gesture, a swipe gesture, and a drawing gesture.

5. The method as claimed in claim 1, wherein the power-saving function enables the touch device to enter a hibernation mode.

6. The method as claimed in claim 1, wherein the power-saving function enables the touch device to power off.

7. A touch device, comprising:

a touch control interface having a touch sensitive area and a displayed area;

a direction sensor unit serving to detect a direction of the touch device and provide direction information of the touch device; and

a controller connected to the touch sensitive area, the displayed area and the direction sensor unit, and determining whether to perform a power-saving function according to the direction information provided by the direction sensor unit and a gesture detected on the touch sensitive area of the touch control interface.

8. The touch device as claimed in claim 7, wherein the direction sensor unit is an accelerometer sensor.

9. The touch device as claimed in claim 7, wherein the power-saving function is performed when detecting the gesture present on the touch device and determining that the direction of the touch device is out of the preset viewing angle.

10. The touch device as claimed in claim 9, wherein the direction of the touch device is determined to be out of the preset viewing angle, an angle included between the direction of the touch device and an X axis corresponding to a horizontal direction of the touch device is greater than the preset viewing angle.

11. The touch device as claimed in claim 9, wherein when the direction of the touch device is determined to be out of the preset viewing angle, an angle included between the direction of the touch device and a Y axis corresponding to a vertical direction of the touch device is greater than the preset viewing angle.

12. A method for controlling a touch device to power on performed by the touch device, the method comprising steps of:

receiving direction information of the touch device;

determining if the touch device is oriented to a direction that is within a preset viewing angle according to the direction information;

detecting a power-on gesture being present on the touch device; and

performing a power-on function when detecting that the power-on gesture is present on the touch device and determining that the direction of the touch device is within the preset viewing angle.

13. The method as claimed in claim 12, wherein the power-on gesture is made by multiple fingers simultaneously touching the touch device.

14. The method as claimed in claim 12, wherein the power-on gesture is made by two fingers simultaneously touching two opposite edge portions of the touch device.

15. The method as claimed in claim 12, wherein the direction information of the touch device includes X-axis information and Y-axis information with coordinates respectively varying in an X axis corresponding to a horizontal direction of the touch device and in a Y axis corresponding to a vertical direction of the touch device.

16. The method as claimed in claim 12, wherein the preset viewing angle is determined according to a specification of a display portion of the touch device.

17. The method as claimed in claim 12, wherein the preset viewing angle is configured through a setting of the touch device.

18. The method as claimed in claim 12, wherein the power-on function serves to power on the touch device.

19. The method as claimed in claim 12, wherein the power-on function serves to wake up from a hibernation mode of the touch device.

20. A touch device, comprising:

a touch control interface having a touch sensitive area and a displayed area;

an accelerometer sensor providing direction information of the touch device; and

a controller connected to the touch sensitive area, the displayed area and the accelerometer sensor, and determining whether to perform a power-on function according to the direction information provided by the accelerometer sensor and a power-on gesture detected on the touch sensitive area of the touch control interface.
