1 is a block diagram for explaining an eye movement apparatus according to the present invention.

Referring to FIG. 1, the eye movement device 10 improves visual symptoms caused by VDT (Visual Display Terminal Syndrome) syndrome occurring in a modern society. That is, the eye movement device 10 provides any one of a virtual reality (VR), an augmented reality (AR), and a mixed reality (MR) To induce blinking of the eyes to improve visual acuity and dry eye syndrome. In addition, the eye movement device 10 can perform eye movement only by the image without additional hardware, thereby enhancing the price competitiveness. The eye movement apparatus 10 includes a main body 100 and an image providing apparatus 200.

The main body 100 is mounted on the head of the user. The main body 100 is a frame formed in the form of an HMD (Head Mounted Display), and may be mounted on the head of the user, preferably in a form to wrap around the back of the user. Also, the body 100 is formed of a light material such as a plastic material so that fatigue to the weight is minimized even if the user mounts the body for a long time.

The image providing apparatus 200 is coupled to the main body 100 in a direction opposite to the left and right eyes of the user. The image providing apparatus 200 outputs any one of a virtual reality, an augmented reality, and a mixed reality including a background image and an object whose brightness is adjusted. Accordingly, the image providing apparatus 200 can guide the user's left and right eyes to blink. That is, the image providing apparatus 200 adapts to the bright light of the eyes and the sensitivity to the light is reduced. The light adaptation that grasps the shape, color and the like of the object and the light adaptation By repeating the dark adaptation to increase the shape of the eye and the dark adaptation to grasp the motion of the object, the eye can not follow the adaptation of the light and can induce the blinking of eyes for unconsciousness or quick adaptation. Here, the object may be any one of a figure, a letter, a company logo, a puzzle, and a character. Also, the image providing apparatus 200 may apply an image including various objects to at least one of advertisement, education, movie, and game. Meanwhile, the image providing apparatus 200 may be a terminal capable of outputting at least one of a virtual reality, an augmented reality, and a mixed reality, and may preferably be a smart phone.

Here, the eye movement device 10 may be a separate type in which the main body 100 and the image providing device 200 are detachably attachable, or may be a one-piece type that is not detached when coupled.

Here, the set value may include object information, brightness information, reproduction time, and the like included in the output image. The communication unit 210 can receive user input using wired / wireless communication. Also, the communication unit 210 can transmit user information such as compliance with light to an external terminal, which will be described later.

The sensing unit 220 senses the blinking of the eyes of the left and right eyes of the user responding to the image. The sensing unit 220 may sense the number of occurrences of the eye flicker of the left eye and the right eye. The sensing unit 220 may include a camera, an infrared sensor, or the like.

The control unit 230 controls the output of the image. The control unit 230 controls the adjustment of brightness of the image. The controller 230 calculates the compliance of the left eye and the right eye with respect to the number of occurrences of the eye flicker sensed by the sensing unit 220. [ At this time, the control unit 230 can determine that the compliance degree increases as the number of occurrences of the eye flickering decreases. The controller 230 may output an image having a brightness that is opposite to the brightness of the currently output image in order to lower the compliance with the light as the compliance with the light increases. This allows the user to increase the frequency of eye blinks and improve dry eye syndrome. In addition, the controller 230 may perform light sense training on the pupil of the user through the output of the image from the pupil of the retina to the optic cell (cone cell and rod cell) to improve the visual acuity. Here, the wide angle means the ability to sense the presence or absence of light rays and the intensity of light rays. That is, the wide angle corresponds to visible light (wavelength range of about 380 nm to 780 nm), which is a ray that can be seen by the naked eye.

The display unit 240 outputs the image of any one of the virtual reality, the augmented reality, and the mixed reality whose brightness is adjusted. The display unit 240 may include a touch screen function. Accordingly, the display unit 240 can also serve as an input unit (not shown) for directly inputting user input. The display unit 240 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display display).

The storage unit 250 stores the background image of the image and the contrast information of the object. The storage unit 250 stores object information included in the image. That is, the storage unit 250 stores at least one of the shape, color, size, and position of the object. The storage unit 250 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory) (Random Access Memory), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM) A magnetic disk, and / or an optical disk.

The body 110 may have various shapes such as a rectangular parallelepiped, a cylinder, and a disc for convenience of the user, and may have a rectangular parallelepiped shape. In this case, the distance between the one end and the other end of the body 110 may be 5 cm to 20 cm, but the present invention is not limited thereto and may be changed according to the size of the image output from the display unit 240. For example, the distance between one end and the other end of the body 110 may be long if the image size is large, and may be short if the image size is small.

The eyepiece portion 120 is formed at one end of the body 110 so as to be in contact with the user's face so that the eyes of the user can be blocked from each other. The eyepiece portion 120 is formed of an elastic member so as to be in contact with the face of the user, so that friction, compression, etc., which may occur when the eyepiece portion 120 is closely contacted, can be minimized. The eyepiece 120 may also be of sufficient size to enable the wearer of the glasses. The eyepiece section 120 includes a left eyepiece section 121 and a right eyepiece section 123. The left eye eyepiece portion 121 is a portion where the left eye of the user is closely contacted, and blocks the light coming from the outside from entering the left eye. The right eye eyepiece 123 is a portion where the right eye of the user is closely contacted, and blocks the light coming from the outside from entering the right eye.

The fixing portion 130 is formed to cover the back of the user from both sides of the eyepiece portion 120 to fix the eyepiece portion 120 and the face of the user in close contact. The fixing part 130 may be formed in a band shape, and the length of the band may be adjusted according to the head size of the user. In the meantime, although the fixing part 130 is shown in the form of a band in the drawing, it is not limited thereto, and the body 100 may be formed in a helmet shape so that a separate fixing part 130 is not formed.

At this time, the image providing apparatus 200 outputs the first object 310 and the second object 320, and the first object 310 and the second object are respectively displayed on the left eye eyepiece 121 and the right eye eyepiece 123, So that they are spaced apart from each other. The image providing apparatus 200 also outputs a background screen 310 for adjusting the overall brightness of the image 300. At this time, the image providing apparatus 200 can alternately output the images 300 having the opposite brightness.

That is, the user can view the first object 310 and the background screen 330 in the left eye and the second object 320 and the background screen 330 in the right eye, When the binocular vision image 300 is viewed, the first and second objects 310 and 320 are overlapped with the left and right eyes of the background 330 as a single object 300). Through this, the user can improve the visual acuity by increasing the frequency of eye flicker, improving the dry eye syndrome, and performing wide angle training from the pupil to the retinal photoreceptor. Further, the user can improve the inner strabismus by viewing the first object 310 and the second object 320 through binocular vision.

The image providing apparatus 200 can maximize the contrast training due to the brightness difference to the user. Here, the lightness of light is quantitative differentiation of the light sensation, and it is related not only to the lightness and the lightness of the physical brightness but also to the sensitivity of the retina, and the sensitivity is related to the degree of eye fatigue. Therefore, eye fatigue can be alleviated through training on contrast. 4A) in which the background screen 330 is white and the first object 310 and the second object 320 are included, and the first image 310 2 images (FIG. 4B) are alternately output in a repetitive manner.

Meanwhile, the image providing apparatus 200 can colorize the first object 310 and the second object 320 to maximize the contrast training due to the brightness difference to the user. The image providing apparatus 200 can output the image 300 using Purkinje's phenomenon. Here, the Furukene phenomenon means that when the light is weak, the eye becomes sensitive to the light of a shorter wavelength than the long wavelength. In other words, the user can feel the brightest yellow and darkest green birds in the brightest place.
