Problems solved by technology

[0007] However, even though many people know that they should not keep facing the computer screen all the time and should keep an appropriate viewing distance, they often unconsciously keep their eyes on the screen and close to the screen. The obvious decrease of the degree, for those who are already myopic, will lead to a deepening of the degree

Embodiment 1

[0074] If the computer has a built-in or external timer and distance measuring sensor, the timer can be used to monitor the time that the user continues to face the computer display screen, and at the same time, the distance between the user and the computer display screen can be monitored through the distance measuring sensor, finally achieving the goal of preventing myopia Purpose. Among them, there is a built-in or external camera on the computer, and a face recognition software system is built-in or connected in series on the host computer. When the user turns on the computer, the face recognition software system will trigger a timer and a distance sensor after recognizing the face. Its implementation is as image 3 As shown, the specific steps are as follows:

[0075] S301: After the face recognition software system recognizes a face, it triggers a timer to detect the time that the user's face continues facing the computer display screen, and triggers the ranging sensor ...

Embodiment 2

[0084] When the electronic display device is a mobile phone or an e-reader, the specific steps will not be repeated here. The mobile phone or e-reader can also set a timer and a distance sensor on its body to monitor the user's continuous use of the mobile phone or e-reader. And the distance between the user and the mobile phone or e-reader, and remind the user to make corresponding adjustments when the time is long or the distance is close, so that the mobile phone or e-reader has the function of preventing myopia and protecting the health of the user, and realizes the function of mobile phone or e-reader. Or the automatic protection of the user's eyes by the e-reader to achieve the purpose of preventing myopia. In addition, the current mobile phones on the market, especially smart phones, have many functions. If the user keeps turning on the timer and the distance sensor, it may cause other functions to run slowly or even make mistakes. The distance sensor is turned on and o...

Abstract

The invention discloses a vision protection method. The vision protection method comprises the following steps of: monitoring time of a human face continuously facing an electronic display device; judging the relationship of the sizes of the time of the human face continuously facing the electronic display device and a preset threshold; and triggering a preset vision protection functional operation when the time is larger than or equal to the threshold. The invention further provides a vision protection system, wherein the vision protection system can monitor the time of the human face continuously facing the electronic display device and the distance between the human face and the electronic display device and carries out a certain protection measure when the time or the distance is close to the threshold, so that the electronic display device has the functions of preventing nearsightedness and protecting vision health, can automatically protect eyes of a user and avoids of the nearsightedness or the increase of nearsightedness degree due to incorrect usage of the eyes when the user uses the electronic device.

Description

technical field [0001] The invention relates to a vision protection device, in particular to a vision protection method and system capable of recognizing the state of a human face and prompting the user to take a break in time. Background technique [0002] Eyes are the most important organ in human perception, and about 80% of the knowledge and memory in the brain are obtained through the eyes. Eyes are used for reading and recognizing characters, looking at pictures and paintings, seeing people, and enjoying beautiful scenery. The eyes can distinguish different colors and different lights. Eyes are the source of most of our information. [0003] In today's society, with the popularization of computers, practitioners in all walks of life cannot do without computers. Using computers for a long time has become an unavoidable form of work and life for modern people. Among those people who cannot live without computers, some are indulging in front of the screen all day long ...
