Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen control method for preventing eye fatigue and eye dryness,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen control method and an operation terminal thereof, a screen control method for preventing eye fatigue and eye dryness, and an operation terminal thereof.

Today, thanks to the development of electronics, communication technologies, and the Internet, smartphones have become a necessity for modern people. The functions of smart phones such as telephone, data search, photo shoot, video production editing, data transmission storage, social network (SNS) activities, translation, cultural creation, drama and film and sports appreciation cover most of the scientific and cultural activities. With the addition of the Internet of things and artificial intelligence technology, smartphones are expected to be used in politics and diplomacy beyond the scope of life-friendly technology.

Smartphone users are projected to reach 2.1 billion in 2016 and to 2.77 billion in 2020 (Stastista "worldwide smartphone users worldwide from 2014 to 2020"), Which is about 27% of the World Bank Data, which means that smartphone dependency will increase even more in terms of information utilization and diffusion.

Koreans spend an average of 3 hours per day using a smartphone (Platum, July 2016). 20 of them were the longest with 4 hours and 9 minutes, while those in their teens used 3 hours and 18 minutes, while those in their 40s and 50s used 2 hours 47 minutes and 1 hour 46 minutes, respectively. When you use a smartphone, you focus your attention on the screen, and the greater your interest in movies and sports, the greater your immersion. This can lead to eye fatigue, especially dry eye, which requires prolonged use precautions.

In many cases, there is a close correlation between smartphone use and dry eye. For example, the higher the penetration rate of smartphones and the longer the duration of use, the higher the prevalence of dry eye, which can lead to eye fatigue and decreased vision due to the immersion of the screen. In particular, air can become more severe in many situations, such as dry winter, congenital, aging tears, or wearing contact lenses.

In order to prevent deterioration of eye health due to the immersion of the screen, Korean Patent Laid-Open Publication No. 10-2014-0120158 discloses a display screen in which the screen brightness is different according to a user viewing the smartphone.

However, such existing screen brightness control methods have limitations in preventing eye fatigue and dryness of the eyes. In other words, the most effective way to prevent eye fatigue and dry eyes is to close your eyes frequently or to rest your eyes while viewing the screen.

Therefore, it is urgent to develop an application (APP (application)) to prevent eye diseases by frequently closing eyes while watching the screen or guiding the eyes to rest periodically.

Korean Patent Publication No. 10-2014-0120158

The technical problem of the present invention is to provide means for ocular dryness and eye fatigue prevention caused by use of a smartphone for a long time.

In the screen flicker process, a character or a shape may be blinked on the screen as a default frequency set in advance.

The screen flicker process may display a character or a shape on the screen as a user correction frequency reflecting the frequency increase / decrease amount selected by the user in the basic frequency.

In the screen flicker process, the frequency increase / decrease amount is determined according to the measured status parameter, and the character or the shape as the parameter correction frequency reflecting the frequency increase / decrease amount in the basic frequency can be blinked on the screen.

The state parameter is the humidity of the weather. The screen flicker process increases the frequency increase / decrease amount as the humidity of the weather is lower than the reference humidity, decreases the frequency increase / decrease as the humidity of the weather is higher than the reference humidity, The frequency of the parameter correction can be determined.

The state parameter is a fine dust concentration of the weather, and the screen flickering process decreases the frequency increase / decrease amount as the fine dust concentration of the weather is lower than the reference concentration of fine dust. When the fine dust concentration of the weather is higher than the reference concentration of fine dust The frequency increase / decrease amount may be increased and the parameter correction frequency may be determined based on the basic frequency.

The state parameter is the degree of eye congestion of the user. The screen flicker process decreases the frequency increase / decrease amount as the degree of eye congestion of the user is lower than that of the congestion standard, and decreases as the degree of eye congestion It is possible to determine the frequency of parameter correction by increasing the weight loss and reflecting it on the basic frequency.

The degree of eye congestion of the user can be determined through the user's eye image photographed through the camera mounted on the user terminal.

The state parameter is a user age, and the screen flicker process can determine the parameter correction frequency by increasing the frequency increase / decrease amount as the user age is higher than the reference age and reflecting it on the basic frequency.

The user age may be a user age extracted through a user's face image photographed through a camera mounted on the user terminal.

The user terminal may be provided with an eye health application of the present invention to perform screen control for preventing eye fatigue and dry eye.

According to the embodiment of the present invention, it is possible to prevent eye fatigue and dry-eye of the user by flickering and displaying letters and shapes at the time of movie reproduction. In addition, by determining the blinking period of letters and shapes differently depending on the surrounding environment, it is possible to increase the prevention efficiency of eye fatigue and eye dryness.

As shown in FIG. 3, the present invention is a screen control method for controlling a screen to prevent a user's eye fatigue and eye drying by a user terminal 100. The screen control method includes a video object type capturing process S320, ), And a screen flicker process (S340).

The video object type identification process (S320) is a process for determining the type of video object displayed on the screen when the video object is displayed on the screen (S310). It is determined whether the video material output on the screen of the user terminal 100 is a moving image or a still image.

Here, the moving image refers to a moving image of the contents such as an animation, a movie, a broadcast (drama, a relay broadcast, etc.), and the still image refers to a still image such as a news media reading, an SNS activity, .

Accordingly, different screen controls for preventing eye fatigue and dry eye of the user are performed according to the type of video displayed on the screen of the user terminal 100. [

First, when the detected video object type is a still image, a message for temporarily turning off the screen is displayed, or a message for prompting the user to close the eyes is displayed. In the case of a still image, the user can take his or her eyes off the screen at any time, thereby guiding the user to open their eyes for a while or automatically turn off the screen for a few minutes.

Useful app for users who view long post (news, fiction, webtoons, etc). Allows the eye to fully rest by automatically turning off the screen at specific time intervals (eg, 30 minutes). The sleep interval and sleep time can be selected by the user.

On the other hand, in the case where the video object type is a moving image, a screen flicker process (S340) is performed to display a character or a shape blinking on the screen. In the case of moving pictures, it is difficult to remove the eyes from the one-view screen, so that letters or shapes are flickered on the screen in order to prevent eye dryness and eye fatigue in consideration of this state.

The term "blinking" refers to turning off and on, and the letters and shapes on the moving picture screen are blinked as set basic periods as shown in FIGS. 4 and 5. Such blinking of letters and shapes can stimulate the eyes of the user who watches the video, and if the user blinks intentionally according to the blinking period of letters or shapes, it can prevent eye fatigue and dryness of the eyes .

This type of text is useful for avoiding the most unobtrusive viewing of the screen, and allows the user to input text that is flickering (for example, "blink" or "blink"). In addition, 'shape' can be a simple figure (circle, square, star), or it can include all things such as photos (person, family, lover, scenery) or emoticons (people, flowers, trees, animals, , Emoticons, etc., can be selected from the stored file of the user terminal 100.

On the other hand, in the screen flicker process (S340), a character or a shape is displayed on the screen in a blinking manner as a default frequency set in advance. The frequency of blinking of the normal person is about 10 times per minute, and the basic frequency of blinking can be determined at 10 times per minute.

The present invention can flicker a character or a figure as a default frequency to be set in advance, but it can be implemented so as to blink a character or a figure with increasing or decreasing a basic frequency according to a user setting or a state parameter.

First, a method of flickering letters and figures by increasing or decreasing the basic frequency according to the user setting will be described.

This is to allow the user to select the appropriate frequency according to the individual state of the flicker frequency. For this purpose, the screen flicker process (S340) flickers the character or shape on the screen as a user correction frequency that reflects the frequency increase / decrease amount selected by the user in the basic frequency.

For example, if the first user selects the frequency 1 step increase, the character or shape is displayed blinking on the screen as the user correction frequency increased to 11 times / min at the basic frequency of 10 times / min, If the first user selects to decrease the frequency by one level, the character or shape is flickered on the screen as the frequency of user correction reduced to 9 times / min at the basic frequency of 10 times / min.

On the other hand, a method of flickering letters and figures with increasing or decreasing the basic frequency according to the state parameter will be described.

In the screen flicker process S340 according to the status parameter, the frequency increase / decrease amount is determined by the measured status parameter, and the character or shape is flickered on the screen as the parameter correction frequency reflecting the frequency increase / decrease amount in the basic frequency. Such state parameters may include weather humidity, fine dust concentration of the weather, degree of eye congestion of the user, and user age. The humidity of the weather or the fine dust concentration can be received from the weather service center server in real time or can be measured and used directly from the user terminal 100.

First, it is explained that the parameter correction frequency is determined when the state parameter is the humidity of the weather.

Since humidity is a major cause of eye dryness, the humidity forecast provided by the user terminal 100 is automatically linked to the blink rate. According to the Meteorological Agency's data for 2016, the average humidity of the metropolitan area during the past 30 years is 75% and 60% in the winter. While there is no significant difference between the seasonal mean values, the daily variation of humidity can be very large. Since the user terminal 100, which is a smart phone, predicts the hourly humidity, the frequency of blinking can be automatically adjusted when the user terminal 100 utilizes the humidity.

To this end, as shown in FIG. 6, the screen flicker process S340 increases the frequency increase / decrease amount as the humidity of the weather is lower than the reference humidity, decreases the frequency increase / decrease amount as the humidity of the weather is higher than the reference humidity, To determine the parameter correction frequency.

 Since the evaporation rate of tears is inversely proportional to humidity, it is possible to automatically correlate the blink rate with the average humidity (75%) of the past 30 years in the reference humidity. For example, if the humidity is 50% at a particular time, the frequency of blink per minute may be increased to 15 times [= 10 x (75/50)], so that the frequency of parameter correction can be determined. However, since there is physical variation among individuals, it is possible to implement such a manual adjustment.

Secondly, it is explained that the parameter correction frequency is determined when the state parameter is the fine dust concentration of the weather.

An app that takes into account the humidity and the amount of fine dust that can increase eye fatigue. As the concentration of fine dust increases, the amount of sticking to the cornea increases proportionally. Therefore, it is possible to adjust the "fine dust good" status to 10 times per minute, which is the basic frequency to be flickered, so that the frequency of blotching increases as the fine dust concentration increases.

For this, as shown in FIG. 7, in the screen flicker process (S340), as the fine dust concentration of the weather is lower than the fine dust reference concentration, the frequency increase / decrease amount is decreased. As the fine dust concentration of the weather is higher than the fine dust reference concentration The frequency increment / decrement is increased to reflect the basic frequency to determine the parameter correction frequency.

Thirdly, it is explained that the parameter correction frequency is determined when the state parameter is the degree of eye congestion of the user.

An app that reflects the degree of congestion caused by eye dryness and eye fatigue. Congestion caused by a foreign body or lack of oxygen, such as dry, fine dust, or wearing a contact lens, is an important indicator of eye fatigue.

For this, as shown in FIG. 8, the screen flicker process (S340) decreases the frequency increase / decrease as the degree of eye congestion of the user is lower than that of the congestion standard, and decreases as the degree of eye congestion The weight loss is increased, and the frequency of parameter correction is determined based on the basic frequency.

The degree of eye congestion of the user can be determined through the user's eye image photographed through the camera mounted on the user terminal 100 and the parameter correction frequency is determined using the degree of automatic eye congestion .

Fourth, it is explained that the parameter correction frequency is determined when the state parameter is the user age.

According to the National Statistical Office's 2016 statistics for the elderly, the proportion of elderly people over 65 years old is expected to increase to 12.2% in 2013, 24% in 2030 and 40% in 2060. This means that the aging of smartphone users will also accelerate. It is necessary to increase the frequency of eye blinking because the use of smartphone is likely to increase eye fatigue in the elderly due to decrease of tear secretion due to aging.

For this, as shown in FIG. 9, the screen flickering process (S340) increases the frequency increase / decrease amount as the user age is higher than the reference age, and reflects the increase / decrease frequency in the basic frequency to determine the parameter correction frequency. Therefore, the frequency of blinking according to the user's age is adjusted to be higher than the reference frequency (10 times per minute).

The user age can be directly inputted from the user, but the user age extracted through the user's face image photographed through the camera mounted on the user terminal 100 can be used.

The embodiments of the present invention described above are selected and presented in order to facilitate the understanding of those skilled in the art from a variety of possible examples. The technical idea of the present invention is not necessarily limited to or limited to these embodiments Various changes, modifications, and other equivalent embodiments are possible without departing from the spirit of the present invention.
