FIG. 5 is a block diagram of a control method of the touch device of the present invention.

Regarding the present invention, in the touch device, the end function is performed in a manner that does not use a power button, and a possible embodiment thereof is as follows: As shown in FIG. 1 , the touch device 10 includes, but is not limited to, a smart phone, a tablet computer, a personal digital assistant, a digital player, etc.; the touch device has a touch interface and a touch device. The interface has an Active Area AA. In addition to performing specific functions (such as answering a call), the visible area AA of the touch device 10 is generally relative to the user's line of sight, in other words, under normal use conditions. The viewable area AA of the control device 10 should be within the viewing angle of the user's line of sight. A general touch interface includes a touch panel and a display. Taking a liquid crystal display as an example, the specification has a certain range of viewing angles, and the visible area AA can be determined by a viewing angle on the display specification.

The control method of the present invention mainly detects whether the user makes a specific gesture on the touch interface, and detects whether the visible area AA deviates from the viewing angle range of the user's line of sight to determine whether to perform an end. Features.

In the following description, several cases of deviating from the range of the viewing angle will be proposed, but it must be noted that the following conditions are merely examples, and are not intended to limit the deviation from the range of the viewing angle.
