Touch device and method for controlling the same to perform a power-saving function or a power-on function
First Claim
1. A method for controlling a touch device to power off and power on, wherein the touch device has an accelerometer sensor, a touch control interface having a touch sensitive area and a controller connected to the accelerometer sensor and the touch control interface, the method performed by the controller and comprising steps of:
- receiving direction information of the touch device sensed by the accelerometer sensor;
determining if the touch device is oriented to a direction that is out of or within a preset viewing angle according to the direction information;
generating coordinate information when a designated power-off gesture or a power-on gesture is detected, at least one of the designated power-off gesture and the power-on gesture being a predetermined stroke pattern from a first touch point to a second touch point;
determining if the designated power-off gesture or the power-on gesture is detected on the touch sensitive area of the touch control interface according to the coordinate information; and
performing a power-saving function on the touch device when the coordinate information of the designated power-off gesture on the touch sensitive area and the direction information of the touch device which is oriented to the direction that is out of the preset viewing angle are detected;
or performing a power-on function when the coordinate information of the designated power-on gesture on the touch sensitive area and the direction information of the touch device which is oriented to the direction that is within the present viewing angle are detected.

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.

15. A touch device, comprising:
-
a touch control interface having a touch sensitive area and a displayed area;
wherein the touch sensitive area is configured to detect a designated power-off gesture or a designated power-on gesture and correspondingly generates coordinate information, at least one of the designated power-off gesture and the power-on gesture being a predetermined stroke pattern from a first touch point to a second touch point;an accelerometer sensor 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 accelerometer sensor, the controller receiving the coordinate information and the direction information, when the coordinate information of the designated power-off gesture is detected on the touch sensitive area and the direction information of the touch device is oriented to the direction that is out of a preset viewing angle the controller performs a power-saving function and enable the touch device to enter a hibernation mode or to power off, or when the coordinate information of the designated power-on gesture is detected on the touch sensitive area and the direction information of the touch device is oriented to the direction that is within a preset viewing angle the controller performs a power-on function and enable the touch device to wake up from the hibernation mode or to power on. - View Dependent Claims (16, 17, 18, 19)
