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

Referring to FIG. 1, the eye movement device 100 improves straining caused by VDT syndrome occurring in a modern society. In other words, the eye movement device 100 intuitively recognizes and corrects strabismus in up and down and left and right by providing an image outputting an object marked with a mark at the left eye and right eye, thereby improving the visual acuity of the user . Here, the image may be any one of virtual reality (VR), augmented reality (AR), and mixed reality (MR). The eye movement apparatus 100 includes a main body 10 and an image providing apparatus 30. [

The main body 10 is mounted on the head of the user. The main body 10 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 of wrapping 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 30 is coupled to the main body 10 in a direction opposite to the left and right eyes of the user. The image providing apparatus 30 outputs an image including two objects marked with a center mark to induce eye movement so that the left and right eyes can be corrected for strabismus in up, 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 30 may apply the contents of the image including various objects to at least one field of advertisement, education, movie, and game. The image providing apparatus 30 may be a terminal through which at least one of a virtual reality, an augmented reality, and a mixed reality may be output, preferably a smart phone.

At this time, the eye movement apparatus 100 outputs any one of a virtual reality, an augmented reality, and a mixed reality including two objects, so that the user intuitively recognizes his or her left and right diagonal shifts, It is possible to improve the distortion by tracking the objects output to the image. The eye movement device 100 includes a main body 10 serving as a frame and an image providing device 30 for outputting an image.

The main body 10 includes a body portion 11, an eyepiece portion 12, a fixing portion 15, and a coupling portion 16.

The trunk portion 11 is formed as an empty space between one end and the other end, and the other end is opened. The trunk portion 11 may have various shapes such as a rectangular parallelepiped, a cylinder, and a disc for the convenience of the user, and may preferably have a rectangular parallelepiped shape. In this case, the distance between the one end and the other end of the trunk portion 11 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 portion 34. For example, the distance between one end and the other end of the trunk section 11 can be long if the image size is large, and can be short if the image size is small.

The eyepiece portion 12 is formed at one end of the body portion 11 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 contact portion 12 is formed of an elastic member so as to be in contact with the user's face, thereby minimizing friction, compression, The eyepiece 12 may also be of sufficient size to enable the wearer to wear glasses. The eyepiece portion 12 includes a left eyepiece portion 13 and a right eyepiece portion 14. The left eye eyepiece portion (13) is a portion where the user's left eye is closely contacted, and blocks the light coming from the outside from entering the left eye. The right eye eyepiece 14 is a part where the right eye of the user comes in close contact with the viewer's eyes and blocks the light coming from the outside from entering the right eye.

The fixing part 15 is formed to cover the back of the user from both sides of the eyepiece part 12 and fixes the eyepiece part 12 and the face of the user in close contact with each other. The fixing part 15 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 15 is shown in the form of a band in the drawing, the present invention is not limited thereto, and the main body 10 may be formed in a helmet shape so as not to form a separate fixing part 15.

The engaging portion 16 is formed at the other end of the body 11 to engage and fix the image providing device 30. At this time, the engaging portion 16 can be engaged with and fixed to the opposite surface of the surface on which the display portion 34 is formed. Also, although not shown in the drawing, a cover (not shown) may further be provided on the rear surface of the surface where the engaging portion 16 and the image providing device 30 are coupled. The cover can protect the image providing device 30 from an external impact and block the light coming from the outside from entering the gap where the image providing device 30 and the body part 11 are joined.

The image providing apparatus 30 is coupled to the body 11 such that the display unit 34 faces the eyepiece 12. The image providing apparatus 30 outputs two objects 50 spaced apart by a predetermined distance through the display unit 34. At this time, the image providing device 30 allows the first object 51 including the first mark 53, which is one of the two objects 50, to be viewed only in the left eye part 13, So that the second object 52 including the second mark 54 can be seen only in the right eye part 14. The image providing apparatus 30 may set the distance between the first object 51 and the second object 52 such that at least the line of sight of the left eye can not see the second object 52, 51 can not be seen.

That is, when the user views the object in the unison view, the user can view only the first object 51 through the left eye and only the second object 52 through the right eye. Also, when the user views the object in the binocular position, the user can see that the first object 51 and the second object 52 overlap each other. At this time, according to the state in which the first marks 53 included in the center of the first object 51 and the second marks 54 included in the center of the second object 52 are superimposed on each other in a consistent manner, The presence and degree of strabismus can be recognized. A detailed description thereof will be given with reference to FIGS. 4 to 9. FIG.

4 is a view for explaining how an image output from an image providing apparatus according to an exemplary embodiment of the present invention is provided to a user rather than a strait, FIG. 5 is a view illustrating a screen, Fig.

3 to 5, the image providing apparatus 30 outputs an image including two objects 51 and 52 to the user. Accordingly, the user can intuitively recognize the presence or absence of strabismus while tracking the two output objects 51 and 52. That is, when the user recognizes that the upper and lower sides are strabismus, it can be judged that there is a problem in the upper rectus muscle, the lower rectus muscle, the superior oblique muscle, and the lower oblique muscle. .

If the user's left eye 71 and right eye 72 are not diagonal, the user can intuitively recognize the screen as shown in FIG. 5 through binocular vision. That is, since the line of sight of the left pupil 73 and the right pupil 74 of the user are aligned with the first object 51 and the second object 52, respectively, The first object 51 and the second object 52 are recognized as overlapping screens. In detail, the user can recognize a screen in which the first mark 53 and the second mark 54 formed at the center of the first object 51 and the second object 52 overlap each other and become a single mark have.

On the other hand, the image providing device 30 displays a scale on at least one of the marks 51 and 52 of the first object 51 and the second object 54 so that the user intuitively displays the left eye pupil 73 and the right eye Thereby helping to perceive the gaze direction of the pupil 74 numerically. For example, a scale mark may be displayed on the second mark 54 for numerically representing strabismus, and the distance between each scale and the scale is set to one prism. Here, the prism is a unit for measuring the amount of strabismus. The prism is called a prism when a deviation of 1 cm occurs at a distance of 1 m, and when there is a deviation of 3 cm, it is called a prism. Therefore, the user who is not strained can recognize that the image is not self-distorted by confirming the image overlapping with the center of the first mark 53 at the center of the scale displayed on the second mark 54. [

FIG. 6 is a view for explaining how an image output from the image providing apparatus according to an exemplary embodiment of the present invention is provided to a user with a diagonal line, FIG. 7 is a view Fig. FIG. 7 (a) is a view showing a case where the user corresponds to medial strabismus and lower-side strabismus during strabismus, and FIG. 7 (b) shows a case where the user corresponds to lateral strabismus and upper-side strabismus during strabismus.

3, 6 and 7, the image providing apparatus 30 outputs an image including two objects 51 and 52 to the user. Accordingly, the user can intuitively recognize the presence or absence of strabismus while tracking the two output objects 51 and 52.

If at least one of the user's left eye 71 and right eye 72 is strained, the user can intuitively recognize the screen as shown in Figs. 7 (a) and 7 (b) through binocular vision. That is, since the line of sight of at least one of the left pupil 73 and the right pupil 74 of the user is not in line with the first object 51 and the second object 52, And the center of the second object 52 are overlapped with each other.

That is, the left pupil 73 of the user is deviated in the direction of the eye to the second object 52, not in the first object 51, and the pupil of the right eye 75 has a straight line direction with the second object 52 Or if the user's left pupil 73 has a line-of-sight method with the first object 51 and the right pupil 74 is deviated to the first object 51 other than the second object 52 , The user can have strabismus.

For example, when the user is an inner strabismus 2 prism and the lower side diagonal 2 prism, the user recognizes the screen as shown in FIG. 7 (a) through the user recognition screen 75. In other words, the user can recognize the degree of straining with respect to himself / herself by recognizing that the first mark 53 is shifted two spaces to the left and two spaces upward, based on the graduation center displayed on the second mark 54. [

Also, if the user is 1.5 prism of outer sash and 1 prism of upper sash 1, the user recognizes the screen as shown in FIG. 7 (b) through the user recognition screen 75. That is, the user can recognize the magnitude of the diagonal deviation by recognizing that the first mark 53 is shifted 1.5 columns to the right and 1 column to the lower side on the basis of the scale center displayed on the second mark 54.

FIG. 8 is a view for explaining how a user with strabismus improves visual acuity through an image output from an image providing apparatus according to an embodiment of the present invention. FIG. In which the visual acuity of the subject is improved. FIG. 9A is a view showing a case where the user corresponds to medial strabismus and lower-side strabismus during strabismus, and FIG. 9B is a view showing a case where the user corresponds to lateral strabismus and upper-side strabismus during strabismus.

Referring to FIGS. 3 and 7 to 9, the image providing apparatus 30 continuously outputs an image including two objects 51 and 52 to the user, thereby improving the sight of the user.

When at least one of the left eye 71 and the right eye 72 of the user is strained, the user can intuitively recognize the screen as shown in Figs. 7 (a) and 7 (b) through binocular vision. At this time, the image providing device 30 can continuously output an image including the two objects 51 and 52 to calibrate the eye with strabismus.

For example, if the user is a 2-prisms in the inner strabismus and a 2-prisms in the lower case and the image providing apparatus 30 continuously outputs images, Recognize the screen. That is, the user recognizes that the center of the first mark 53 is moved to the center of the scale indicated by the second mark 54, which means that the inner and lower sides of the user are corrected.

In addition, when the user is 1.5 prisms of outer sash and is an upper prism of 1 diagonal and the image providing device 30 continuously outputs images, the user recognizes the screen as shown in FIG. 9 (b) do. That is, the user recognizes that the center of the first mark 53 is moved to the center of the scale indicated by the second mark 54, which means that the outer and upper-side strains of the user are corrected.

Therefore, in the image providing apparatus 30 of the present invention, the user perceives only the sagittal in the left-right direction and not the perceived sagittal is corrected, but the user perceives the sagging in the up-down direction, can do.
