1 is a block diagram illustrating an eye movement device according to the present invention.

Referring to Figure 1, the eye movement device 10 improves the ocular symptoms caused by the Visual Display Terminal Syndrome (VDT) syndrome that occurs in modern society. That is, the eyeball movement apparatus 10 provides an image of any one of a virtual reality (VR), an augmented reality (AR), and a mixed reality (MR) with respect to objects having different movements to the binocular vision of the user's left and right eyes. By tracking this object, we can improve ocular symptoms through eye movement to the extraocular muscles of the eye. The eye movement device 10 provides an image of one of a virtual reality (VR), an augmented reality (AR), and a mixed reality (MR) of an object having a perspective to track the object by the left and right eyes of the user. Due to the stretching effect of the lens and ciliary muscles can improve the eye syndrome. The eye movement device 10 provides an image of any one of a virtual reality (VR), an augmented reality (AR), and a mixed reality (MR) including a background and an object whose brightness is controlled, so that the user's left and right eyes are closed. Flashing can be induced to improve vision and dry eye. In addition, the eyeball movement device 10 can increase the price competitiveness by performing the eyeball movement only with the content of the image without installing additional hardware. The eyeball movement device 10 includes a main body 100 and an image providing device 200. Here, the eyeball movement device 10 may be a detachable type detachable to the main body 100 and the image providing device 200, or may be an integral type that is not separated when combined.

Body 100 is mounted to the head of the user. The main body 100 is a frame formed in the form of a head mounted display (HMD), and may be preferably mounted on the head of the user in a form surrounding the back of the user. In addition, the body 100 is formed of a light material such as a plastic material to minimize the fatigue to the weight even if the user is mounted for a long time.

The image providing device 200 is coupled to the main body 100 in a direction facing the left and right eyes of the user. The image providing apparatus 200 outputs an image of any one of virtual reality, augmented reality, and mixed reality including two objects having different movements. Through this, the image providing apparatus 200 may induce one of the two objects to be tracked through the left eye and the other one to be tracked through the right eye.

In addition, the image providing apparatus 200 outputs an image of any one of virtual reality, augmented reality, and mixed reality including an object having a perspective. In this way, the image providing apparatus 200 may induce the user's left and right eyes to track an object having a perspective.

In addition, the image providing apparatus 200 outputs an image of any one of a virtual reality, an augmented reality and a mixed reality including a background screen and an object whose brightness is adjusted. In this way, the image providing device 200 may induce the user's left and right eyes to blink. That is, the image providing apparatus 200 is a phenomenon in which the eye adapts to the bright light and the sensitivity to the light is reduced, and the light adaptation to grasp the shape and color of the object and the eye adapts to the low light state By repeating the dark adaptation to detect the contrast and the movement of the object with increasing sensitivity to the eye, the eye can not follow the adaptation of the light, thereby inducing the occurrence of eye blink for unconscious 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 content including various objects to at least one field of advertisement, education, movie, and game. On the other hand, the image providing device 200 is a terminal that can output at least one image of the virtual reality, augmented reality and mixed reality, preferably may be a smart phone.

Referring to FIG. 2, the communication unit 210 receives a user input including a setting value for outputting an image. Here, the set value may include object information, playback time, and the like included in the output image. The communication unit 210 may receive a user input using wired or wireless communication. In addition, the communication unit 210 may transmit user information such as eye movement amount, eye muscle exercise amount, eye fatigue degree, compliance with light, and the like, to an external terminal.

The detector 220 detects eye movements of the left and right eyes of a user who tracks an image. The detector 220 may detect eye movement by detecting pupil movements of the left and right eyes. The sensor 220 detects the movement of the lens with respect to the left and right eyes of the user who tracks the image. The detector 220 may detect the thickness of the lens of the left and right eyes to detect the movement of the lens. The detector 220 detects eye blinks for the left and right eyes of the user in response to the image. The detector 220 may detect the number of occurrences of eye blinks of the left and right eyes. The detector 220 may include a camera, an infrared sensor, or the like.

The controller 230 controls the output of the image.

When outputting an image for inducing eye movement using object tracking, the controller 230 controls two objects included in the image to have irregular trajectory movements while maintaining a predetermined interval. Preferably, the controller 230 controls the movement of the trajectory so that two objects move in the same trajectory in a large frame, but finely controls the trajectory to have a difference in the trajectory. Through this, the user may receive different visual stimuli in the left eye and the right eye without receiving an uncomfortable stimulus such as dizziness, nausea, etc. since the two objects do not have a big difference in movement. In addition, the controller 230 may control the output to set different colors and sizes to distinguish the two objects.

The controller 230 calculates an eye movement amount of the user by using eye movements for the left and right eyes sensed by the detector 220. The controller 230 may calculate the amount of eye movement by calculating a moving distance of the movement of the pupil of the eye. At this time, the controller 230 may also calculate the eye muscle exercise amount using the movement distance and the movement direction for the movement of the pupil. That is, the controller 230 determines that the movement amount for the medial rectus muscle and the lateral rectus muscle increases when the eyeball moves left and right, and the movement amount for the inferior oblique muscle and the upper superior muscle muscle increases when the eyeball moves diagonally up and down.

The controller 230 controls at least one of the shape, color, size, and trajectory of the object of the image using the eyeball momentum. For example, if the amount of eye movement is lower than the reference value, the controller 230 changes the at least one of the shape, color, and size of the object to increase the concentration of the user to raise the amount of eye movement by the reference value. In addition, the controller 230 may control the movement of the object as a trajectory for stimulating the eye muscles with low eye muscle exercise when the eye muscles have lower eye muscle exercise.

When outputting an image for inducing eye movement using perspective, the controller 230 controls the position of the object by giving a perspective to the object included in the image. The controller 230 calculates fatigue degrees for the left and right eyes using the motion of the lens detected by the detector 220. At this time, the controller 230 may determine that the fatigue of the left and right eyes decreases as the time for changing the thickness of the lens is shortened.

Here, the lens becomes thinner when viewed near, and thicker when viewed far. At this time, when only looking continuously close to the lens, the thickness of the lens is hardened in a thin state, in order to prevent this phenomenon, by changing the thickness of the lens while looking far away should reduce the fatigue of the left and right eyes. In particular, when the thickness of the lens is hardened in a thin state, since it takes a long time to change the thickness of the lens, it can be determined that the faster the time for the thickness change of the lens, the lower the fatigue of the left and right eyes.

As described above, in order to change the thickness of the lens, the controller 230 may control the object to be output when the object alternates between a first image located at a near point and a second image located at a far point in time.

In addition, the controller 230 may control the object to output a third image that moves the near view and the far view. In this case, the controller 230 may further include an auxiliary object for confirming that the viewpoint of the object is moved to control the output of the third image.

That is, the controller 230 cross-outputs the near view image and the far view image to stimulate the ciliary muscles. Through this, the ciliary muscles can contract and relax and change the thickness of the lens to obtain a stretching effect on the left and right eyes.

When outputting an image for inducing eye movement using contrast, the controller 230 controls the output of the image. The controller 230 controls the adjustment of the brightness of the image. The controller 230 calculates compliance with light of the left and right eyes using the number of occurrences of eye blinks sensed by the detector 220. In this case, the controller 230 may determine that the compliance is increased as the number of eye blinks decreases. When the compliance with light increases, the controller 230 may output an image having brightness opposite to that of the currently output image in order to decrease compliance with light again. Through this, the user may improve dry eye syndrome by increasing the frequency of eye blinks. In addition, the controller 230 may improve vision by performing light sense training on eye cells (cone cells and rod cells) of the retina from the pupil of the user through the output of the image. Here, the wide angle means the ability to distinguish the presence or absence of light rays and the intensity of light rays by the function of sensing light rays. That is, the wide angle corresponds to visible light (wavelength range of about 380 nm to 780 nm), which is a light beam that we can see with the naked eye.

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

The storage unit 250 stores information of an object included in the image. That is, the storage unit 250 stores at least one information of a shape, color, size, and trajectory of the object. The storage unit 250 may include a flash memory type, a hard disk type, a media card micro type, a card type memory (for example, SD or XD memory), Random Access Memory (RAM), Static Random Access Memory (SRAM), Read-Only Memory (ROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Programmable Read-Only Memory (PROM), Magnetic Memory, It may include at least one storage medium of a magnetic disk, an optical disk.

Referring to Figure 3, the eyeball movement device 10 is formed in the form of HMD to provide an image to the user.

The trunk portion 110 may have various shapes such as a rectangular parallelepiped, a cylinder, and a disc for convenience of the user, and may preferably have a rectangular parallelepiped shape. At this time, the body portion 110 may have a distance between one end and the other end of 5 cm to 20 cm, but is not limited thereto and may be changed according to the size of an image output from the display 240. For example, the distance between one end and the other end of the trunk 110 may be longer if the size of the image is large, and may be shorter if the size of the image is small.

The eyepiece 120 is formed at one end of the body portion 110 to be in contact with the user's face, so that the eyes of the user's left and right eyes can be blocked from each other. The eyepiece 120 may be formed of an elastic member that is in contact with the user's face to minimize friction, compression, etc. that may occur when the eyepiece is in close contact. In addition, the eyepiece 120 may have a size sufficient to be used by a person wearing glasses. The eyepiece 120 includes a left eyepiece 121 and a right eyepiece 123. The left eyepiece 121 is a portion in which the user's left eye is in close contact with the eyepiece, and blocks light from the outside from entering the left eye. The right eyepiece 123 is a portion in which the user's right eye is in close contact with the eye, and blocks light from the outside from entering the right eye.

The fixing part 130 is formed in a form surrounding the back of the user's back from both sides of the eyepiece 120 to secure the eyepiece 120 and the user's face 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 size of the head of the user. Meanwhile, although the fixing part 130 is illustrated as being formed in a band shape in the drawing, the present invention is not limited thereto, and the main body 100 may be formed in a helmet shape so as not to form a separate fixing part 130.

Coupling unit 140 is formed on the other end of the body portion 110 to couple and fix the image providing device 200. At this time, the coupling unit 140 may be coupled to and fixed to the surface opposite to the surface on which the display unit 240 is formed. In addition, although not shown in the drawings, a cover (not shown) may be further included on a rear surface of the coupling unit 140 and the image providing apparatus 200 that are coupled to each other. The cover may protect the image providing apparatus 200 from an external shock, and block light from the outside from entering a gap where the image providing apparatus 200 and the body part 110 are combined.

The image providing device 200 is coupled to the body 110 such that the display 240 faces the eyepiece 120.

The object 310 is controlled to be an invisible distance.

That is, when the user sees the object in monocular vision, the user may see the first object 310 in the left eye, the second object 320 in the right eye, and in the binocular vision, the left and right eyes As a result, the first object 310 and the second object 320 can be simultaneously viewed. Meanwhile, the image providing apparatus 200 controls the trajectory of the first object 310 and the second object 320 to have different movements, such that the left and right eyes of the user are the first object 310 and the second object. Track 320 can maximize the effect of the eye movement occurs.

The eye movement device 10 detects the eye movement generated while the left eye and the right eye respectively track two objects in step S330 of FIG. 8 with a camera or an infrared sensor.

In operation S370, the eye movement device 10 calculates the eye movement amount and the eye muscle exercise amount of the user using the detected eye movements for the left and right eyes. The eyeball movement device 10 calculates the movement distance for the movement of the pupil of the eyeball to calculate the eyeball momentum. At this time, the eyeball movement device 10 also calculates the eye muscle movement using the moving distance and the moving direction for the movement of the pupil. Here, the eyeball movement device 10 determines that the movement amount for the medial rectus muscle and the lateral rectus muscle increases when the eyeball moves left and right, and the movement amount for the inferior oblique muscle and the superior root muscle increases when the eyeball moves up and down and diagonally. .

In operation S390, the eyeball movement device 10 controls the object of the image using the calculated eyeball movement and eye muscle movement. When the eyeball movement amount is lower than the reference value, the eyeball movement device 10 changes the at least one of the shape, color, and size of the object to raise the concentration of the user and raises the eyeball movement amount by the reference value. In addition, the eyeball movement device 10 controls the movement of the object as a trajectory that can stimulate the eye muscles with low eye muscle momentum when the eye muscle momentum is lower than the reference value. That is, the eyeball movement device 10 may control at least one of the shape, color, size, and trajectory of the object.

Referring to FIG. 10, the eyeball movement device 10 is formed in an HMD form to provide a user with any one image of virtual reality, augmented reality, and mixed reality. At this time, the eyeball movement device 10 outputs an object having a perspective, thereby inducing the left and right eyes of the user to track the object. The eyeball movement device 10 includes a main body 100 serving as a frame and an image providing device 200 for outputting an image.

Here, since the description of the main body 100 has been described above, it will be omitted.

The image providing device 200 is coupled to the body 110 such that the display 240 faces the eyepiece 120. The image providing device 200 outputs the object 400 having a perspective through the display 240. In this way, the user may be provided with images for the near and far views, thereby maximizing the contraction and relaxation of the ciliary muscles.

FIG. 11 is a diagram illustrating a first image provided by the image providing apparatus of FIG. 10, FIG. 12 is a diagram illustrating a second image provided by the image providing apparatus of FIG. 10, and FIG. 13 is a diagram of FIG. 10. Figure is for explaining the movement of the eye through the eye movement device.

10 to 13, the image providing apparatus 200 outputs an object 400 having a perspective through the display unit 240. In this case, the image generally has a near viewpoint of 10 cm to 50 cm and a far viewpoint of 1 m to infinity.

The image providing device 200 alternately outputs the object 400 of FIG. 11A, which is an image located at a near point, and FIG. 11B, which is an image located at a far point in time. In detail, the image providing apparatus 200 alternately outputs FIG. 11A where the object 300 is located at 10 cm to 50 cm and FIG. 11B where the object 400 is located at 1 m to infinity.

The image providing apparatus 200 outputs FIG. 12B, which is an image in which the object 300 moves a near view and a far view. In detail, the image providing apparatus 200 outputs FIG. 12B in which the object 300 repeatedly moves from 10 cm to infinity. In this case, the image providing apparatus 200 may include FIG. 12A, which is an image including the auxiliary object 450 located at 50 cm to 1 m so that the user can more effectively recognize the movement of the object 400. Therefore, the image providing apparatus 200 may output FIG. 12B through which the object 400 passes through the auxiliary object 450 while repeatedly moving from 10 cm to infinity.

Through this, the user's eyeball 500 may perform eyeball movement. When the object 400 output from the image providing device 200 outputs a far point of view, the user relaxes the ciliary muscles 520a, contracts the ciliary platoon 530a, and thins the lens 510a, thereby providing a remote object. 400 can be seen. In addition, when the object 400 output from the image providing device 200 outputs a near point of view, the user contracts the ciliary muscles 520b and relaxes the ciliary platoon 530b so that the lens 510b becomes thick, thereby providing a near object. 400 can be seen.

At this time, when the user sees the near point of view for a long time, the lens 510b is hardened due to prolonged pressure of the ciliary muscle 520b, thereby deteriorating the vision of the eye. In order to improve such deterioration of vision, the image providing apparatus 200 may repeatedly release the near and far views, thereby releasing the hardened lens.

1 and 14, the eye movement method provides an image of any one of virtual reality, augmented reality, and mixed reality for an object having perspective to induce the user's left and right eyes to track the object. Through this, the eye movement method can improve the vision by gently releasing the frozen lens of the user.

In step S410, the eyeball movement device 10 is mounted to the head of the user. Here, the eye movement device 10 is combined with the main body 100 in a direction opposite to the user's left and right eyes and the user's head is fixed, virtual reality, including an object having a perspective, augmented It includes an image providing device 200 for outputting any one image of reality and mixed reality. In addition, the eye movement device 10 is formed in the form of HMD, either the main body 100 and the image providing apparatus 200 is detachable or any one of the body 100 and the image providing apparatus 200 is one of the integral type. It may be formed in the form.

In operation S430, the eyeball movement device 10 outputs an image. The eye movement device 10 outputs an image of any one of virtual reality, augmented reality, and mixed reality to track an object in which the left and right eyes of the user have a perspective. That is, the eyeball movement device 10 outputs an image repeatedly showing a near point and a far point. Through this, the user can improve vision by giving a stretching effect to the lens of the left and right eyes.

Referring to FIG. 15, the eyeball movement device 10 is formed in the form of an HMD to provide a user with any one image of virtual reality, augmented reality, and mixed reality. In this case, the eyeball movement device 10 outputs an image in which brightness is adjusted, thereby inducing eye movements for the left and right eyes of the user. The eyeball movement device 10 includes a main body 100 serving as a frame and an image providing device 200 for outputting an image.

The image providing device 200 is coupled to the body 110 such that the display 240 faces the eyepiece 120. The image providing device 200 outputs an image 600 whose brightness is adjusted through the display unit 240. In this case, the image providing apparatus 200 outputs the first object 610 and the second object 620, and the first object 610 and the second object 620 are the left eye eyepiece 121 and the right eye eyepiece, respectively. Outputs a predetermined interval so that it can be seen only at (123). In addition, the image providing apparatus 200 also outputs a background screen 630 for adjusting the overall brightness of the image 600. In this case, the image providing device 200 may alternately output the image 600 having the opposite brightness.

That is, when the user views the image 600 in monocular vision, the user may see the first object 610 and the background screen 630 in the left eye, and the second object 620 and the background screen 630 in the right eye. When the image 600 is viewed in both eyes, the image of the first object 610 and the second object 620 overlaps one object with the left eye and the right eye with the background 630 as the background ( 600). Through this, the user can improve the dry eye syndrome by increasing the number of eye blinks, and improve vision by performing wide-angle training on pupils of the retina from the pupil. In addition, the user may improve the medial strabismus by viewing the first object 610 and the second object 620 through binocular vision.

FIG. 16 illustrates a first image provided by the image providing apparatus of FIG. 15, FIG. 17 illustrates a second image provided by the image providing apparatus of FIG. 15, and FIG. 18 illustrates an image of the present invention. It is a flowchart for explaining the eye movement method according to the third embodiment.

15 to 18, the image providing apparatus 200 outputs an image 600 whose brightness is adjusted through the display unit 240. Here, the image 600 includes a first object 610, a second object 620, and a background screen 630 for setting the overall brightness of the image to increase the concentration of the user.

The image providing device 200 may maximize contrast training due to the difference in brightness to the user. Here, the brightness of light is the quantitative discrimination of light sensation, and is related to the sensitivity of the retina as well as the large and small physical luminosity, and the sensitivity is related to eye fatigue. Therefore, training on contrast can alleviate eye strain. In detail, the image providing apparatus 200 may repeatedly include FIG. 16A, which is an image including a white background 630, a first object 610, and a second object 620, and FIG. 16B, which is a black full screen. Controls to output alternately.

On the other hand, the image providing apparatus 200 may further maximize the contrast training due to the brightness difference to the user by assigning a color to the first object 610 and the second object 620. The image providing device 200 may output an image 600 using a Purkinje's phenomenon. Here, the Purkinje phenomenon means that when the light is weak, the eyes are more sensitive to short wavelength light than long wavelength. That is, the user may feel the bright blue-green bird in the brightest place in the yellow, dark place. In detail, in the image providing apparatus 200, the background screen 630 is white, and FIG. 17A including the first object 610 and the second object 620, the background screen 630 is black, and the first screen is 630. At least one of the object 610 and the second object 620 includes cyan, FIG. 17C where the entire screen is black, and the background screen 630 is white, and the first object 610 and the second object. At least one of the objects 620 is controlled to be sequentially repeated while again outputting FIG. 17D and FIG. 17A including yellow. In this way, the user may increase the concentration of the image 600 by changing the color through the first object 610 and the second object 620 as well as the difference in brightness felt in the background screen 630.
