Problems solved by technology

The disadvantage of this display method is: if the person is standing or sitting upright, the direction from the forehead to the jaw just points to the direction of gravity of the earth (that is, the gravity sensing direction is 90 degrees to the horizontal direction of the eyes), and the gravity sensor can be correctly set to align the face direction
However, when the human body is lying on its side or the device is placed horizontally, since the direction from the forehead to the jaw is not 90 degrees to the direction of gravity (such as placing the tablet screen on a horizontal table, the observer approaches the table from any direction) , when looking down at the content on the screen, because the direction of gravity of the earth points vertically to the back of the screen), the gravity sensor cannot automatically align the text and graphics on the screen with the direction of sight

Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific examples.

[0012] In each of the following embodiments, the front camera on the device performs face recognition to determine the user's face direction, and then adjusts the text and images on the screen to automatically align the line of sight (ie, the line of text and the level of the line connecting the eyes).

[0013] The specific implementation plan is:

[0014] Through the face recognition software, set the horizontal direction of the user's eyes to be the horizontal direction of the text or graphics display; set the up and down directions of the mouth to be the vertical direction of the text or graphics display; other points on the face can also be set to determine The direction of the face, such as the horizontal direction of the face is determined by the eyebrows and ears, and the upper and lower directions are determined by the nose, jaw, forehead, etc. When wearing glasses, t...

Abstract

The invention discloses a new application of a method for controlling display directions of screen characters and images by using facial recognition. The method for controlling the display directions of the screen characters and the images by using the facial recognition can solve the problems that the orientation of a screen needs to be calibrated for the screen character and the image display of a traditional electronic mobile product and the traditional electronic mobile product is inconvenient. Screen contents are automatically aligned to the face through facial recognition, and the screen contents are automatically adjusted to an optimum watching angle through the facial recognition.

Description

technical field [0001] The invention discloses a new application. Background technique [0002] Existing portable (mobile) electronic products generally have a display screen for us to watch information or control equipment. Unlike fixed electronic products (such as TVs, desktop computers, etc.), portable electronic products seldom move the screen and have a relatively fixed viewing direction. It is difficult to fix the viewing direction because it needs to be carried and changed frequently. [0003] And when we use this kind of mobile electronic products, such as taking out the mobile phone from the pocket, when we need to watch or touch the screen, we usually need to complete an action first: that is, rotate and adjust the mobile phone, and change the direction of the text and images on the mobile phone screen. Be consistent with the user's face direction (that is, when the user faces the device screen, the top of the screen text or graphics faces the direction of the for...
