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.
