Human eye and screen distance monitoring method and device and terminal

Abstract

The invention discloses a human eye and screen distance monitoring method and device and a terminal, and the method comprises the steps: collecting and processing a sound signal in real time, so as toobtain a first pre-judgment data set; collecting and processing a distance signal used for representing the distance between the human face and the screen to obtain a second pre-judgment data set; performing pre-judgment according to the first pre-judgment data set and / or the second pre-judgment data set to obtain a pre-judgment result; and if the pre-judgment result is judged to be that follow-up judgment is needed, starting a front camera to shoot a picture, and analyzing the picture to obtain a follow-up judgment result. The distance monitoring is carried out by using the microphone, the distance sensor and the camera of the intelligent terminal, and new hardware does not need to be introduced, so that the cost is reduced. By introducing the pre-judgment link, the probability that thecamera is frequently started is reduced, the privacy of a user is protected, and the power consumption is also reduced. And through the use of multiple criteria, the judgment precision is improved, excessive reminders are reduced, and the user viscosity is enhanced.

Description

technical field [0001] The invention relates to the application field of intelligent terminals, in particular to a method, device and terminal for monitoring the distance between human eyes and a screen. Background technique [0002] The popularity of smart terminals has provided more convenience for people's lives, but at the same time the incidence of myopia in my country has increased significantly. Recent research reports show that the myopia rate of primary school students exceeds 25%, the myopia rate of junior high school students reaches 70%, and the myopia rate of high school students More than 85%. Watching the electronic screens of smart devices at close range for a long time is an important reason for inducing myopia. [0003] In order to reduce the incidence of myopia and avoid the deterioration of myopia patients, the existing technology proposes to monitor the distance between the user and the screen of the screen terminal in the smart terminal, and remind the ...

Problems solved by technology

For example, the technical solution for monitoring distance based on infrared sensing requires the introduction of new hardware to increase costs; the technical solution for estimating the distance between the user and the screen terminal based on image processing combined with the user's eye distance in the image relies too much on the camera, resulting in increased power consumption and User Privacy Risks

[0005] In addition, the technical solution for monitoring the distance between the user and the screen of the screen terminal in the prior art generally has the problem of a single criterion. As a result, the judgment results are not accurate enough, and the resulting frequent reminders have caused a decline in user experience and reduced user viscosity
