Problems solved by technology

[0003] In the prior art, since the visual fatigue test must make the test subject be in a certain visual fatigue state, it is necessary to go through a long process of natural visual fatigue before performing the visual fatigue measurement, such as letting the testee be in a computer or tablet Watching videos or reading e-books on mobile phones and other devices takes 2 to 3 hours. However, this process takes a long time, which is not conducive to the extensive development of visual fatigue testing, and also greatly affects the efficiency of visual fatigue testing.

Embodiment 1

[0049] figure 1 It is a flow chart of the visual fatigue stimulation method provided in Embodiment 1 of the present application. This embodiment is applicable to the situation of visual fatigue testing, and the method can be executed by the visual fatigue stimulation device provided in the embodiment of the present application. / or implemented in the form of hardware, and can be integrated into visual fatigue stimulation terminals.

[0050] Such as figure 1 Shown, described asthenopia stimulation method comprises:

[0051] S110. Display a first image in a determined display area, and display a second image in a flash on the first image, and the second image covers the first image during the flash display.

[0052] Wherein, the determined display area may be a middle position under the test interface. For example, if the test terminal is a mobile phone, it can be in the middle of the screen under the mobile phone test interface. The first image can be understood as a refere...

Embodiment 2

[0067] figure 2 It is a flow chart of the visual fatigue stimulation method provided in the second embodiment of the present application. On the basis of the above-mentioned embodiments, this embodiment is specifically optimized as follows: the method further includes: displaying interference images in areas other than the determined display area, switching backgrounds at regular intervals, and dynamically displaying the first image in the determined display area One or more setting methods in an image are used to carry out an enhanced test; correspondingly, when the reaction time meets the first standard, and the operation accuracy rate meets the second standard, it is determined that the visual fatigue of the subject has been stimulated. , including: when the average reaction time in each current fixed time period within the total statistical measurement time increases by 10%-20% relative to the average reaction time in the initial fixed time period, and the correct rate of...

Embodiment 3

[0077] image 3 It is a flow chart of the visual fatigue stimulation method provided in Embodiment 3 of the present application. This embodiment is specifically optimized on the basis of the above-mentioned embodiments. After determining that the visual fatigue of the subject is stimulated, the method further includes: counting the average reaction time in the fixed time period at the end of the total measurement time relative to The increase of the average reaction time within a fixed period of time begins, and the correct rate of operation within the total measurement time is counted; according to the statistical results, the visual fatigue test results of the subjects are determined.

[0078] Such as image 3 Shown, described asthenopia stimulation method comprises:

[0079] S310. Display the first image in the determined display area, and display the second image in flash on the first image, and the second image covers the first image when displayed in flash.

[0080] S...

Abstract

The embodiment of the present application discloses a visual fatigue stimulation method, device, storage medium and terminal. The method includes: displaying a first image in a determined display area, and flashing a second image on the first image, and the second image covers the first image when flashing; Operation information for recording the number of occurrences of the second image; when the operation information meets the preset standard, it is determined that the visual fatigue of the subject is stimulated. By adopting the technical solution provided by the present application, it can be realized that the visual fatigue of the testee can be stimulated quickly, thereby improving the efficiency of the visual fatigue test.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vision testing, and in particular, to a visual fatigue stimulation method, device, storage medium and terminal. Background technique [0002] In modern life, video display terminals such as mobile phones, tablet computers, and TVs are increasingly popular, making people's visual systems always in a state of tension. If it lasts for a long time, it is easy to have symptoms of visual fatigue such as dry eyes, eye astringency, eye pain, and even headaches and inattention. This sub-health state will affect our work and life, and in severe cases, it will cause eye organic diseases such as myopia and eye diseases. [0003] In the prior art, since the visual fatigue test must make the test subject be in a certain visual fatigue state, it is necessary to go through a long process of natural visual fatigue before performing the visual fatigue measurement, such as letting the testee be ...
