Description

Visual stress test device

The present invention relates to a visual stress test apparatus, and in particular, by forming a character constituting a target in black on a white background, but forming a combination of dots that are spaced apart from each other, noise corresponding to a blurring phenomenon around black The present invention relates to a visual stress test apparatus that enables the amplification of this to be amplified, and allows a subject to easily distinguish between a visual stress increase color and a decrease color through this.

Visible light refers to electromagnetic waves in an area visible to the human eye. Visible light generally refers to an electromagnetic wave having a wavelength of 400 nm to 700 nm, but it is known that some people detect visible light of a wavelength ranging from 380 nm to 800 nm.

Among visible light, visible light of a transparent color, commonly called white light, is light that has continuous energy over the entire wavelength range of visible light like sunlight. In other words, it can be said that white light is made by mixing all visible rays in the wavelength range.

This transparent light, that is, white light, visually gives a universal or average stimulus to all people, and this universal stimulus is a large number of individuals depending on the distribution of each person's visual cells, the parallax of the binocular visual perception pathway, and the response of the brain. Different symptoms are expressed.

An example of visual stress caused by a universal stimulus is a situation in which a person feels glare when going out after being indoors on a sunny day and strong sunlight. In this situation, a person shows actions such as covering his eyes or closing his eyes to reduce the irritation of light. These visual stimuli may result from an overall excessive amount of light, or may result from a particularly sensitive response to light in a specific wavelength range. In other words, since light in a range other than the light (color) wavelength currently required for me enters my eyes, a visual avoidance phenomenon may occur, which can be considered a temporary visual stress situation. Such visual stress can be overcome by individual resistance and adaptability in many cases, but some people develop new diseases such as photosensitive syndrome, Allen syndrome, and dyslexia.

A person may feel more uncomfortable by being more stimulated by light in a specific wavelength range. Conversely, a person may feel relatively comfortable with light in another specific wavelength range, and the specific wavelength range of such light may differ from person to person.

Therefore, if each individual can know the color of light that relieves visual stress, visual stress is reduced by applying these colors to devices that can filter the wavelength range of light entering the human eye, such as glasses, sunglasses, and sports goggles. It could be mitigated or minimized.

An example of an apparatus and method for estimating an optimal color capable of alleviating a visual stress situation is disclosed in Korean Patent Registration No. 10-0990000 (hereinafter, referred to as "prior technical literature").

This is to make it usable even when the position or angle of the lighting needs to be changed according to the situation. For example, it may be necessary to emit light from the front or back of the target 130 depending on the situation. In addition, when the lighting unit 120 is composed of a plurality of LED modules, each LED module can simultaneously or continuously cross and emit light of the same color, but simultaneously or continuously cross light of different colors. It is also possible to diverge.

On the opposite side where the inspection window 111 or the lighting unit 120 is formed in the position where the eye of the examinee is directed through the inspection window 111, that is, in the inner space of the housing 110, a letter, a constant A target 130 in which at least one of a pattern and a pattern is formed in black on a white background is disposed. That is, the target 130 is mounted or mounted in the inner space of the housing 110 so that it can be checked through the inspection window 111.

The target 130 may be formed as a printed matter in which letters, certain patterns, patterns, etc. are printed on a white base plate made of a material such as paper or plastic. Alternatively, the target 130 may be formed in a form in which paper on which letters, certain patterns, patterns, etc. are printed is attached to a base plate formed of a material such as other paper, plastic, or metal.

The target 130 may be formed of a color display panel such as LCD or OLED, not in the form of general paper or plastic. In this case, the lighting unit 120 may be disposed at the place of the target 130 and the target 130 is also displayed through the color display panel. In this case, the effect of continuously changing the color of the lighting unit 120 may be implemented in a form in which the light color irradiated or overlaid on the target 130 is continuously changed over the entire color display panel.

The target 130 may be arranged such that two or more targets 130 separated from each other are arranged side by side. In this case, for example, a letter is used in one target 130 and a certain pattern is used in the other target 130 It can be configured to print a pattern.

Since the target 130 may need to be used while replacing various types of ones, it is preferable to be installed detachably to the housing 110. For example, the target 130 may be provided to be inserted into and removed from the inside of the housing 110 through a target insertion slot (not shown) provided at one side of the housing 110.

The lighting unit 120 emits light of various color wavelengths according to a control signal from the lighting control unit 140. To this end, the lighting controller 140 variably controls the color wavelength of light emitted from the lighting unit 120 under control of the computing device 200 connected by wire or wirelessly.

In this way, the illumination control unit 140 controls the illumination color of the illumination unit 120 according to the control of the computing device 200. In this case, the illumination control unit 140 may variably control the illumination color, that is, a color wavelength, of the illumination unit 120 according to an inspection result received from the computing device 200. This is to find an optimal illumination color for the user, for example, a color found to be a color corresponding to a color wavelength without visual stress, according to the results of the visual stress test and the color vision test.

The computing device 200 is a concept including a smart device, a mobile device, a tablet, a computer, and the like, and any one of them may be selectively applied. Visual stress test and color vision test according to the present invention can be performed using the computing device 200, and the results of the visual stress test and color vision test are determined by the visual stress test device 100 according to an embodiment of the present invention, specifically It is transmitted to the lighting control unit 140 to determine a final result, for example, a color having a color wavelength that does not cause visual stress to the subject most.

A program for managing and controlling the lighting control unit 140 for controlling the lighting unit 120 is installed in the computing device 200, and the lighting unit 120 is turned on, turned off, and color is changed through the operation of the program. An operation of providing a control signal for controlling the operation of a light to the lighting control unit 140 may be performed.

In addition, the computing device 200 may form a control signal capable of adjusting a change speed and luminance of a color that is continuously changed and provide it to the lighting control unit 140. In addition, it is possible to receive and store the response of the test subject A, and finally determine a color corresponding to a color wavelength that relieves or minimizes the visual stress of the test subject A. According to the operation of the computing device 200 as described above, the lighting control unit 140 receives a corresponding control signal and controls the lighting unit 120.

The visual stress test apparatus 100 according to the present invention configured as described above includes the configuration of the target 130 in order to allow the test subject to easily select a color corresponding to a color wavelength that receives strong visual stress and does not receive visual stress. Adopt and apply.

Specifically, the target 130 applied to the present invention is a white background as shown in FIGS. 3 and 4 (FIG. 3 corresponds to a photograph of a state in which light is irradiated by the lighting unit 120, It does not appear to be white, but corresponds to a white background) and includes at least one of letters, patterns, and patterns formed in black, but each of the letters, patterns, and patterns is formed by a combination of dots that are spaced apart from each other. .

The target 130 applied to the present invention is basically composed of at least one of letters, patterns, and patterns in black on a white background. That is, the target 130 may be configured by forming a black letter or a black pattern or a black pattern on a white background, or a combination of at least two of black letters, patterns, and patterns. It could be.

Each of the letters, patterns, and patterns constituting the target 130 applied to the present invention configured as described above is not formed entirely in black, as shown in FIG. 3, but is formed with regular black dots. It is configured to be spaced apart from each other at predetermined intervals or irregularly. That is, the letters constituting the target 130 of the present invention are composed of a combination of black dots, but are formed by regularly or irregularly spaced apart from each other.

In this way, when the strokes constituting the letter or the part constituting the pattern or pattern are formed by a combination of black dots, a white space is additionally formed between the black dots and the black dots. In the state of adopting and applying such a configuration, if the color wavelength that gives visual stress to the subject is irradiated, a blurring phenomenon appears around the black color of the letter or pattern or pattern, but due to the white margin between the black point and the black point. Blurry symptoms may be amplified around black, such as letters, so that the test subject can more easily distinguish between the color of increasing visual stress and the color of reducing stress.

The present invention conceives the concept of increasing noise that is blurred by the examinee when the black area to the white area or the white area to the black area is increased, and the letters constituting the target 130 are black. It was formed by a combination of colored dots. As a result, since black dots are spaced apart from each other in the letters constituting the target, a large number of white backgrounds are formed between adjacent black dots, and when the color wavelength that gives visual stress to the test subject is irradiated through this, the test subject The amplified noise can be more easily recognized, and through this, it is possible to more easily distinguish and determine the visual stress increase color and the stress decrease color.

Meanwhile, the target 130 according to the present invention may include various patterns and patterns as well as letters, as described above. However, in particular, when the target 130 according to the present invention is configured by arranging at least one letter as shown in Figs. 3A and 4, the at least one letter is a Gothic type, an initial, and a neutral And it is composed of a jongseong, the strokes are formed by complex connection combinations.

That is, when the target 130 applied to the present invention includes letters and consists of at least one letter, the at least one letter (in FIG. 3 (a) consists of two letters, and ( In a), the same six letters are configured up and down, and Fig. 4(b) illustrates that nine different letters are configured up and down), as described above, are formed by a combination of black dots and at the same time thick It is formed in a Gothic font consisting of strokes, and is configured to have all of the initial, neutral, and final characters in order to improve the complexity of the strokes, and the strokes are formed by connecting and combining complicatedly.

In this way, the letters constituting the target 130 applied to the present invention are preferably formed in a Gothic font composed of thick strokes, so that they can have a complex and messy shape, and furthermore, each letter has an initial, neutral, and final character. It is formed by having all of them, and it is preferable that the strokes are formed by complexly connecting and combining each other.

In order to further increase the complexity of all of the at least one letter or each letter, the at least one letter preferably includes a letter in which at least one of an initial and a final sound is formed by a combination of two consonants, and It is most preferable that all of the endings include a letter formed by combining two consonants.

Figure 4 (a) illustrates that each letter consisting of at least one letter has a finality consisting of two consonants combined, and Figure 4 (b) is a letter consisting of at least one letter It is illustrated that only some letters (life, hunger) in the column have a finality in which two consonants are combined.

However, since the letter formed by combining two consonants for both the initial and the final voice can be considered to be the most complex and messy, each of the letters constituting at least one letter applied to the present invention has the initial and final two consonants. It is most preferably formed in combination. That is, it is most preferable to form a target by forming the initial voice as a combination of two consonants in (a) of FIG. 4.

According to the visual stress test apparatus 100 of the present invention described above, the letters constituting the target 130 are formed in black on a white background, but are formed by a combination of dots that are spaced apart from each other, It is possible to amplify the occurrence of noise corresponding to the blurring phenomenon, and through this, the advantage of allowing the subject to easily distinguish the color of increasing visual stress from the color of decreasing is generated.

In addition, according to the present invention, when the target 130 is composed of letters, the letters are formed in a thick gothic font, and are configured to have both initial, neutral, and ending, and the strokes are formed by complex connection and combination. Therefore, it is possible to further amplify the occurrence of noise with respect to the color (color wavelength) that generates visual stress, and as a result, the effect of allowing the examinee to more easily distinguish between the increased color of the visual stress and the decreased color occurs.

In addition, according to the present invention, since only the shape of the letter constituting the target 130 is variably applied without adding other components, it is possible to distinguish and find the color of increasing and decreasing visual stress more conveniently and inexpensively. There is an effect that allows it to occur.

Hereinafter, a method of determining a color corresponding to a color wavelength for reducing or minimizing visual stress through a visual stress test apparatus according to an embodiment of the present invention will be schematically described.

Prior to performing the inspection method of determining a color for reducing or minimizing visual stress through the visual stress test apparatus according to the present invention, it is preferable to adjust the luminance, that is, the brightness of the lighting unit 120. This is because sensitivity to light varies from person to person, and exposure to a light source having a luminance exceeding an appropriate range may negatively affect the results of the inspection according to the present invention.

In addition, before performing a test method for determining a color for reducing or minimizing visual stress through the visual stress test apparatus according to the present invention, a test for color vision abnormalities such as color blindness, that is, a digital color vision test may be performed first. This is because it is necessary to check the presence of color vision abnormalities and weak color wavelengths by conducting a digital color vision test. Such a digital color vision test may be performed using the computing device 200. However, the method of determining the color for reducing or minimizing visual stress through the visual stress test apparatus according to the present invention is capable of determining the color for reducing visual stress regardless of the presence or absence of color vision abnormality according to the digital color vision test. Color vision testing is not an essential process.

Next, in order to smoothly proceed with the visual stress test of the test subject, it is preferable to variably control the illumination unit 120 to irradiate a continuous color wavelength to the target 130 to stimulate the test subject's visual cells.

Next, the lighting unit 120 is variably controlled to sequentially change to a plurality of colors to irradiate the target 130. For example, the illumination unit 120 is sequentially changed into 7 or more colors including red, orange, yellow, green, blue, indigo and purple to irradiate the target 130, or red, green , Blue and orange are grouped by 2 or 4 are irradiated to the target 130 at a time so that the visual noise is the least so that the color can be selected so that the letters and the like are clearly visible.

For example, when the lighting unit 120 is divided into 7 colors, the wavelength range of each color is, for example, 723 to 647 nm for red, 647 to 585 nm for orange, 585 to 575 nm for yellow, and 575 for green. It can be -492 nm, blue color is 492 to 455 nm, indigo color is 455 to 424 nm, and purple color is 424 to 397 nm. When the lighting unit 120 is controlled to change the color from one color to the next color, the color changes continuously. This can be done by dividing the time finely between two adjacent colors and inserting multiple intermediate colors. The more finely divided time and the more number of intermediate colors inserted, the smoother and smoother the transition between the two colors can be.

In addition, there is a difference in time to respond to color change depending on the test subject.Some test subjects may not adapt to the standard color change rate and thus may not obtain meaningful test results.In this case, it is necessary to slow the color change rate. . On the contrary, some people may not be able to obtain meaningful test results at the standard color change rate, in a different meaning from the above case because they are very adaptable to color change. In this case, the color change rate needs to be a little faster. There is.

Under the control of the lighting control unit 140, in the process of the illumination unit 120 continuously changing the color and irradiating the target 130, the test subject (A) at least one of the black letters, patterns, or patterns At the same time as it looks thinner, identify the point where your eyes feel comfortable and enter this point. The input may be made through an input device such as a keyboard keyboard connected to the computing device 200, or may be input by a test performer according to a hand signal or an audio signal of the test subject A.

At this time, the input of the point of time when at least one of the black letters, patterns, or patterns appears thin and the eye of the subject A is comfortable is among a plurality of colors including red, orange, yellow, green, blue, indigo, and purple. It is approximated to record the color closest to the color at that point in time (of a continuously changing intermediate color), and at this time, the selected color is recorded as the 1-1 color.

Alternatively, unlike colors that continuously change according to the irradiation of the lighting unit 120, the display of the computing device 200 includes seven or more colors including the red, orange, yellow, green, blue, indigo, and purple colors. The color corresponding to the time point can be selected or displayed, and in this case, the examinee A can directly select the corresponding color according to the signal of the examinee A or the examinee. This applies equally to all of the similar steps described below. This completes the first step color selection.

Next, two-stage color selection is carried out. In the second-stage color selection, the color selected in the first-stage color selection is verified whether or not the color selected in the first-stage color selection was an appropriate selection by comparing the color selected in the first-stage color selection with two adjacent colors, respectively, and performing a visual stress relief or minimization check.

To this end, the color is continuously changed between two colors of the first-first color and the first-first color, which is a color of the first-first color prior to the first color, according to a predetermined light emission order. At this time, the examinee (A) inputs the point of time at which one or more of the black letters, patterns, or patterns appear thin and at the same time, the eyes are more comfortable, and among the first-first color or the first color, The color is determined as the 2-1 color and recorded. In this case, as described above, instead of selecting and inputting a viewpoint to find a color corresponding thereto, a corresponding color may be directly selected and inputted through the screen of the computing device 200.

Next, as a second step of the second step color selection, the color is continuously changed between the two colors of the first-first color and the first-second color, which is a color in the order after the first-first color, and the black color The examinee inputs the point of time at which one or more of the letters, patterns, or patterns appear thin and at the same time that the eyes are comfortable, and the color closer to the color at that point of the first-first color or the first-second color is a 2-2 color. And record it.

Subsequently, the determined color 2-1 and the color 2-2 are compared, and if the color 2-1 and the color 2-2 match as a result of the comparison, the color is determined as a third color and recorded. However, if the 2-1 color and the 2-2 color do not match, the color is continuously changed between the 2-1 color and the 2-2 color, and the black text, pattern, or At the same time, one or more of the patterns appear thin, and at the same time, the examinee determines and inputs the point at which the eyes are comfortable. Among the 2-1 color or 2-2 color, a color closer to the color of the input viewpoint is determined as the third color and recorded.

In this way, the final determined color that can alleviate or minimize the visual stress of the subject (A), that is, the third color has been selected, and according to the selected third color, lighting, glasses, sunglasses, glasses for night driving, and monitors The visual stress of the test subject (A) can be greatly reduced by making and using safety glasses and a smartphone LCD protective film.

Although the embodiments according to the present invention have been described above, these are merely exemplary, and those of ordinary skill in the art will understand that various modifications and equivalent ranges of embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the following claims.
