Embodiment 1

[0061] Please refer to figure 1 Embodiment 1 of the present application provides a system control method, which is applied to an electronic device, the electronic device includes a dynamic image acquisition unit and a display unit, and the method includes:

[0062] Step 101: Obtain a facial dynamic image of a human face obtained by the dynamic image acquisition unit.

[0063] Specifically, the dynamic image acquisition unit can be a camera, which collects dynamic images of the facial features of the human body at a relatively comprehensive and obvious angle to the user's facial features, or multiple cameras can be used to perform multi-directional and multi-angle Shooting, and then obtain multi-directional dynamic images for the recognition of human facial feature points, so that the recognition results are more accurate, and it can also make the position change analysis of facial feature points during the operation process more accurate. Of course, in the specific implementa...

Embodiment 2

[0140] Please refer to figure 2 Embodiment 2 of the present invention provides an electronic device including a dynamic image acquisition unit and a display unit, such as a mobile phone, a tablet computer, a notebook computer and other electronic devices, specifically including:

[0141] The dynamic image acquisition unit 201 is configured to acquire the facial dynamic image of the human face obtained by the dynamic image acquisition unit.

Abstract

The invention discloses a system control method and an electronic device. The method comprises: obtaining a facial dynamic image of a human face; obtaining at least three facial feature points; obtaining at least one polygon; determining a specific feature point; determining a position reference point; determining a relative position and a deformation value; and based on the relative position and the deformation value, generating and executing a first control instruction used for controlling a position indication mark. According to the technical scheme provided by the application, only one dynamic image acquisition apparatus needs to be arranged, so that the problems of poor positioning precision and low efficiency of a position indication mark in the prior art are solved; and a user is not required to rotate the head within a wide range in the using process or the electronic device is moved within a wide range relatively, so that the technical scheme provided by an embodiment of the invention has the technical effects of high positioning precision, high sensitivity and high operation efficiency of the position indication mark and good user experience.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a system control method and electronic equipment. Background technique [0002] At present, with the enlargement of the display screens of electronic equipment terminals, the size of the display screens is usually more than 4 inches, and some even reach 6 inches or 7 inches. In practical applications, such as on a bus, when one hand of the user is holding the electronic device terminal while the other hand is holding the handlebar on the bus, due to the hand holding the electronic device terminal Due to the limited length of fingers, it is difficult to operate all display objects on the display screen of the electronic device terminal with one hand. [0003] For this reason, in the prior art, a method of acquiring the position of the tip of the nose on the human face in real time is used to control the electronic device by tracking the movement of the tip of the user's nose....
