Face recognition page display control method and mobile terminal

Abstract

Disclosed are a face recognition page display control method and a mobile terminal. The face recognition page display control method comprises performing face detection on an image collected by a camera device of the mobile terminal and extracting position coordinates of a face area, performing eye positioning on the face area, and recording eye image data; extracting center coordinates of two eyes, computing the angle of a connecting line of the centers of the two eyes and a page datum line, wherein the page datum line is a virtual line of reference in the horizontal direction of a current page; judging whether the angle is larger than or equal to a preset angle threshold value, if so, switching a current page display mode to a portrait display mode or a landscape display mode, and if not, maintaining the current page display mode. The face recognition page display control method is different from an existing gyroscope sensing control method, due to the fact that the judgment standard is the relative angle between the two eyes of a user and the mobile terminal, influences of factors of using postures of the user can be avoided, the accuracy of judgment can be improved, and better experience can be provided for the user.

Description

technical field [0001] The invention relates to human-computer interaction technology, in particular to a face recognition page display control method and a mobile terminal. Background technique [0002] In order to adapt to the display effect of different application occasions, the current digital terminals with display screens such as mobile phones are generally equipped with a horizontal screen display and vertical screen display switching function of the display page. For example, the application of video playback software often requires adjustment of the image display direction. The existing horizontal and vertical screen switching uses G-sensor, that is, the gravity sensor as a detection tool to control the switching timing, and some manually set it through manual menus. Manual settings can accurately reflect the real needs of users, but the operation is relatively cumbersome and the degree of intelligence is low; the G-sensor detection method can realize automatic swi...

AI Technical Summary

Problems solved by technology

Manual setting can accurately reflect the real needs of users, but the operation is relatively cumbersome and the degree of intelligence is low; the G-sensor detection method can realize automatic switching between horizontal and vertical screens, which is more convenient, but the accuracy of its operation has certain limitations. There are various scenarios when moving a terminal, and only relying on the G-sensor to detect the direction of the terminal to judge the display mode required by the user often leads to misjudgment. To achieve the display effect expected by the user, the user experience is not perfect

Some mobile terminals can only make up for this defect by locking the horizontal and vertical screen display through physical buttons or virtual buttons, but this locking method is contrary to the intention of automatic switching, and it is still not convenient enough to increase the user's operation steps
