Description

  The present invention relates to an eyesight training sheet using a pseudo-stereoscopic image and a method for using the eyesight training sheet, that is, an eyesight training method using a printed material and the printed material, and more particularly, using a newspaper or a magazine that is viewed daily. The present invention relates to an eyesight training sheet based on a pseudo-stereoscopic image used by generations and elderly people who view the image, and a method of using the same.

  Recently, electronic civilization, which has achieved rapid development, is increasing the generation of various types of electronic display devices. As a result, a lot of pseudomyopia has been generated and attention to eye health and eyesight has attracted attention. In addition, it is desired to maintain a healthy eye force as long as the lifespan is extended and the population ages.

A conventional eyesight training sheet uses a 15-point paper 40 shown in FIG.
The 15-point paper 40 is, for example, A4 paper with numbers 1 to 5 equidistant from the left to the right, numbers 6 to 10 equidistant from the left to the right at the center, and numbers 11 from the left to the right at the equidistant from the bottom. ~ 15 are displayed.
The trainee holds the 15-point paper 40 with both hands, and first visually recognizes the eyeball by moving the eyeball from the number 1 to 15 with the face facing the number 8 at the front center. Next, it starts from visually recognizing the numbers 1 and 2 and sequentially moves the eyeballs to 13 and 14 in order.
Next, starting with the simultaneous viewing of the numbers 1, 2 and 3, the eyeballs are sequentially moved to 13, 14 and 15 and sequentially viewed.
Furthermore, it starts from visually recognizing the numbers 1, 2, 3 and 4 at the same time by sequentially moving the eyeballs to 13, 14 and 15. Continue for more than 10 minutes every day by increasing the number to be viewed at the same time or starting from 15 in reverse reading order.
Further, the trainee reads the numbers in the same manner by moving the 15-point paper 40 close to the face, and then reads the numbers in the same manner by moving the 15-point paper 40 away from the face. Thus, the ciliary body of the eye and the eye movement muscles are trained.

Japanese Patent Application Laid-Open No. 2002-336317 (Japanese Patent Application No. 2001-179352)

The conventional 15-point paper 40 does not execute the function of the brain for processing information from the eyes, particularly the three-dimensional recognition function, and does not reach the one that activates consciousness, gaze, eye movement, and focus adjustment movement. It was.
The printed matter and sheet shown in Non-Patent Documents 1 to 5 do not repeat the line of sight, the convergence angle, and the focus adjustment.
In Patent Document 1, it was necessary to purchase electronic shutter glasses for observation. Moreover, since the television screen is viewed, there is a hassle of using the television with the consent of the family and others at home and office. Further, in Non-Patent Documents 1-5, it is necessary to always keep these bookstore picture books at hand, and there is a drawback in that eye training is stopped if left unplaced.

The present invention has been devised in order to solve such problems, and is a pseudo-stereoscopic image that can be easily carried out at any time each time a newspaper in hand or a magazine in an office break room is turned over every morning. It is an object to provide an eyesight training sheet and a method of using the same.
Another object of the present invention is to use an eyesight training sheet based on a pseudo-stereoscopic image that can be used in parallel with product / service advertisements and corporate appeals to consumers by using product symbols in the pseudo-stereoscopic image. Is to provide a method.

  The present invention has been made to solve the above problem, and an observer gazes at a pair of similar right and left images arranged in the horizontal direction, with the right eye using the right eye and the left image using the left eye. At the same time, in the two horizontal eyes of the observer, two vertical straight muscles, two outer straight muscles (on the left and right sides of the eyeball) and two vertical oblique muscles provided around the eyeball are provided. The direction of viewing is set by consciously moving, and the ciliary body 62, the chin band 65, and the crystalline lens 61 provided inside the eyeball are consciously moved and focused, and if this state is maintained for a while, the brain The right image and the left image overlap each other by a function of recognizing a solid (visual function) provided, and a pseudo-stereoscopic image having a sense of depth (sunk) is visually between the right image and the left image. The recognized parallel method (parallel), or the right image with the left eye When gazing at the left image, in the two eyes, the two vertical straight muscles, two outer straight muscles (on the left and right sides of the eyeball) and two vertical oblique muscles provided around the eyeball are provided. A function for recognizing the three-dimensional object (visual function) by setting the viewing direction by moving the human eye while consciously moving and setting the focal point by moving the ciliary body 62, the chin band 65 and the crystalline lens 61 provided in the eyeball. A sheet on which the right image and the left image are fixedly displayed so as to realize a crossing method in which a pseudo-stereoscopic image with a sense of popping out (floating) is recognized. The right image and the left image are respectively displayed in a plurality of lines on the surface, and in the adjacent lines, the eye force training sheet arranged so that the right image and the left image gradually move away from each other or approach each other. It is characterized by repeated gaze.

  Adults, children and the elderly, regardless of their age and gender, read the newspaper every morning, and look through the book on the commuter train for 3 minutes. Eye health can be improved and maintained without any special costs.

Before explaining the embodiments of the present invention, the visual acuity and the interpretation structure of the brain, the perspective method using the left and right eyes, and the basic principles of stereoscopic vision will be described.
First, structures and functions known in cerebral physiology and anatomy of the human brain will be described with reference to FIGS.
Recent advances in brain medicine, biological brain scanners, electroencephalogram research and biochemistry, and biochemistry are revealing the human brain structure, various brain functions, and functional parts (distribution positions in the cerebrum).
According to the supervision of Makoto Iwata, an illustrated trivia "The mechanism of the brain", the human brain 10 is composed of a cerebrum consisting of a left and right brain 11 and a right brain 12 that are substantially symmetrical, and a cerebellum 13 below and behind that. The entire brain is covered by the cerebral cortex 14, but there are small auditory areas 16 below the (ears) of the left and right temporal association areas 15, respectively, and left and right below the posterior occipital association 18 (above the cerebellum 13). Each has a small visual area 19.

The cerebral cortex of the sphere is composed of the frontal lobe 20, the parietal lobe 21, the occipital lobe 22 and the temporal lobe 23 in the spatial domain distribution as viewed from the side.
The auditory cortex 16 receives ear information, which is located slightly above the left and right ears and in the lower central part of the temporal lobe 23, while the left and right visual cortex 19 receiving eye information is at the lower end of the rearmost part of the left and right occipital lobes 22. is there.
Furthermore, the cerebrum is functionally composed of five association areas that process and judge information from the five senses, which are the frontal association area 24, the parietal association area 25, the occipital association area 18, the temporal association area 15, This is an exercise association area 26 sandwiched between the frontal association area 24 and the parietal association area 25. Each association area is distributed in the left and right brains, and each association area increases its functionality as the brain develops and grows.

The visual cortex 19 receives color, shape, depth, and movement information from the eyes, and the occipital association area 18 analyzes and integrates the information to judge and recognize the object.
In addition, there is a cross control in the brain. Information and movement on the right side of the body including the right eye are controlled by the left brain, and information and movement on the left side of the body starting from the left eye are controlled by the right brain.
The work of the left hemisphere of the brain is mainly logical thinking and calculation functions such as speaking, writing, and judgment. The right hemisphere, on the other hand, has a function that evenly corresponds to the left and right fields of view, and has comprehensive recognition and operation functions in space. In addition, the right hemisphere functions preferentially for the overall composition of paintings, the recognition of unknown melodies, and the decoding of the entire information of the outside world that enters the sight.

  Next, the basic principle of perspective projection and stereoscopic vision with the left and right eyes is that humans have the same disparity in the horizontal direction where both eyes are aligned even if they are the same object on the left and right eyes. I image. As shown in FIG. 11, when a human is looking at infinity, such as the sun, a distant mountain, or a river, the optical axis (left and right line of sight) that enters the left and right eyes moves in parallel, and the left eye What is visible moves to the right and the same visible to the right eye appears to move to the left. In FIG. 12, in the state where the optical axes are parallel, the parallax S1 of the object near the eye is larger than the parallaxes S2 and S3 of the far object. The disparity gradually decreases as the distance increases. S1> S2> S3.

Further, when an object about 100 meters away from the eyes is viewed, the left and right eyeballs move in the direction in FIG. 13, and the left and right eyes form a convergence angle T with respect to the object being viewed. The convergence angle T1 of the object near the eye is larger than the convergence angle T2 of the far object T1> T2.
The left and right visual areas 19 in FIGS. 9 and 10 receive the color, shape, depth, and movement information from the eyes, and the occipital association area 18 analyzes and analyzes these information. The object is determined by integration and a stereoscopic image is recognized.

The human brain recognizes the three-dimensional image of the object and determines the distance from the convergence angle T in FIG. 13 and the parallax S in FIG. The convergence angles T1 and T2 are originally recognized by the human brain based on the line of sight of both eyes, focus adjustment (crystal lens adjustment), and left / right parallax.
Now, consider the case where the objects B1 and B2 and the printed matter P on which characters are drawn and the objects B3 and B4 are sequentially arranged so as to gradually move away from the front of the human eye in FIG.

When the eyes are focused on the characters of the printed matter P of the transparent base, the optical axes of the left and right eyes intersect on the object (printed matter) P, but the left and right parallaxes of the objects B1 and B2 in front of the printed matter P are Things that are visible to the left eye move to the right, and those that are visible to the right eye appear to move to the left.
FIG. 14 shows a state in which the left eye is covered with the cover C and then viewed with the right eye. In the objects B1 and B2 in front of the transparent plate P, the optical axes of the eyes in FIG. The same objects B1 and B2 that can be seen by the right eye are seen to have moved to the left, and the displacement L1 of the object B1 at a position close to the eyes is larger than the displacement L2 of the far object B2. The farther away, the smaller the shift amount (one element of parallax) becomes smaller (L1> L2, this is defined as a direct proportion, corresponding to the crossing method described later).

In FIG. 14, after that, the right eye is covered with a cover C (not shown), and these are viewed with the left eye. In the objects B1 and B2 in front of the transparent plate P, the same objects B1 and B2 visible to the left eye are respectively right Although it is not shown, it can be easily estimated that the amount of change of the object B1 that is visible in the state of moving to the position near the eye is larger than the amount of change of the far object B2.
The sum of the amount of change of the same object B1 visible to the left eye and the amount of change of the same object B1 visible to the right eye becomes parallax, but in the following description, this amount of change will be described as parallax.
Now, in FIG. 14, beyond the intersection (printed material P), the same objects B3 and B4 that can be seen by the right eye appear to have moved to the right. Further, the distance L3 of the object B3 at a position close to the right eye (transparent plate P) is smaller than the distance L4 of the far object B4 beyond this intersection. The further away from the eye (intersection / printed material P), the larger the parallax (L3 <L4 inversely proportional, corresponding to the intersection method described later).

Although not shown, the same objects B3 and B4 that can be seen by the left eye similarly appear to move to the left, and it can be easily estimated that the shift amount is also inversely proportional.
That is, the direction of change and the amount of change are reversed before and after the intersection (printed material P on the transparent plate) as a boundary.
This is because when you look at your finger in front of the newspaper and bring your finger closer to your eyes and focus on your finger, the stationary newspaper will be out of focus but left and right and full view. I can understand it by spreading out.

Further, in FIG. 16, the parallax will be described in detail. When a human sees an object in the three-dimensional space, that is, the visual target 10a, if the difference between the images in the retina of the left eye 53L and the right eye 53R is processed by the visual cortex 19 in the brain and the occipital association area 18, the depth is perceived. It is considered. Since the left and right eyes 53L and 53R of the human being as an animal are about 4-5 cm apart, the parallax (binocular parallax) is the most important factor for perceiving depth at a short distance.
For ease of understanding now, the target 10a is a cube, and a circle is drawn on the side. The left side 53L of the cube 10a appears wide and the right side 52 appears narrow (elongated oval) in the left eye 53L. This is defined as the left-eye parallax effect.
On the other hand, in the right eye 53R, the right side surface 52 of the cube 10a appears wide (circular), and the left side surface 51 appears narrow (rectangular). This is defined as the right eye parallax effect.

In the human eye in nature, the right and left eye parallax effect degrees and the left eye parallax effect degree and the video correlation coefficient are common rules for all people because the left and right eyes 53L and 53R are about 4-5 cm apart. Follow the sex.
These video correlation counts are defined as the difference and sum of the right-eye parallax effect and the left-eye parallax effect.
On the other hand, in the case of computer video, the right-eye parallax effect degree, the left-eye parallax effect degree, and these video correlation coefficients can be freely changed and set during the video production process. However, if the 3D image data produced by the computer is too far away from the video correlation coefficient for the right-eye parallax effect and the left-eye parallax effect according to a certain regularity in the natural world, Your brain may be confused and you may experience dizziness and nausea.

Next, in FIG. 17, when there is a cube 10a at a distance L1 from the infinity point W (10m behind in human life space), when there is a cube 10a at a distance L2, and when there is a cube 10a at a distance L3. And consider. The distance L2 is exactly the position of newspaper or the like.
When viewing the cube 10a, the cube 10a at the distance L3 close to the observer is large (display area is large), and the cube 10a at the intermediate position distance L2 from the observer is medium (in the display area) and far from the observer. The cubes 10a having the distance L1 are small (display area is small) and are displayed. This is defined as the perspective area ratio according to perspective projection. The perspective area ratio is common to the left and right eyes.

Next, the pseudo stereoscopic video that is the basis of the present invention will be described.
Historically, stereo cameras have been known since the advent of cameras. Take two landscape photographs of people and living space at the same time with two lenses that are approximately 4-5cm horizontally, corresponding to the human right and left eyes. Stereoscopic aerial photographs have been used from the Second World War to today, and here, two aerial photographs can be seen from the sky at the same time with two lenses that are approximately 4-5 cm horizontally close to the left and right eyes. Take a picture of the ground image.
Humans recognize stereoscopic images by arranging photographs developed on the film side by side and viewing them with the left and right eyes simultaneously. In stereo photography, Gandhi is a living photograph, and in 3D aerial photography, Tokyo aerial photography is known.
There is a dedicated device that arranges the photos left and right, the left eye photo with the left eye, and the right eye photo with the right eye. This device has a white wall between the left and right eyes so that the left and right fields of view are not mixed with each other and independent The left and right images are combined by the brain so that the brain recognizes the pseudo stereoscopic image. This corresponds to the parallel method described later. An aerial photograph observation expert can easily recognize a three-dimensional image of an uneven area from two left and right photographs without using the parallel method to provide left and right separation walls with the naked eye.

Next, the medically known physiological structure of the eye will be described below.
In FIG. 18, an eyeball 60 is composed of a cornea, an iris, a lens 61, an internal vitreous body, a ciliary body 62, a retina, a macular, and an optic nerve that can be seen from the outside. The outer surface of the eyeball 60 is coupled to the six eye muscles 63 shown in FIG. 19 so that the eyeball 60 can move to see the outside. The eye muscles 63 are two vertical straight muscles, two external and internal (on the left and right sides of the eyeball) straight muscles, and two vertical oblique muscles.
The eyeball 60 is wrapped in a soft bag body 64 continuous with the cornea, and the eyeball 60 moves when the six eye muscles 63 pull the bag body 64 from a specific position.

The crystalline lens 61 is a disc having a soft thickness, and as shown in FIG. 20, a ciliary body 62 is positioned so as to surround the peripheral portion thereof, and the ciliary body 62 has a substantially annular shape, and its outer peripheral portion is formed of a cornea. The bag body 64 is connected to a continuous position. There is a crystalline lens 61 on the inner peripheral portion of the ciliary body 62, and the inner peripheral portion of the ciliary body 62 and the outer peripheral portion of the crystalline lens 61 are connected by an infinite number of thread-like tiny bands 65.
When the ciliary body 62 relaxes, the chin band 65 is tensioned and the crystalline lens 61 is pulled and compressed to become flat, and the eye is in a state of looking far away.
On the other hand, when the ciliary body 62 contracts, as shown in FIG. 21, the chin band 65 is loosened and the crystalline lens 61 swells and becomes thick, and the eye is in a state of looking closer.

When the human is consciously looking far or near, the ciliary body 62, the chin band 65, and the crystalline lens 61 move and adjust the focus, and when looking at the surroundings, the six eye muscles 63 and the ciliary body. 62, the chin band 65, and the crystalline lens 61 move simultaneously.
Now, for long hours of watching TV, working on an electronic display device, long hours of video games for children, and normal long-time document work, the viewing direction of the eyes is constant, and the focal distance to the target image being viewed Is constant. Accordingly, the six eye muscles 63, the ciliary body 62, the chin band 65, and the lens 61 of the eye become insufficient in movement, causing various health problems.

With human muscles that can be touched indirectly from the outside, it is possible to recover from fatigue by stroking with hands, bending and stretching, and stretching back.
The six eye muscles 63, the ciliary body 62, the chin band 65, and the crystalline lens 61 of the eye are originally small and fine muscles inside the head, so that they can be arbitrarily kneaded, bent and stretched, or stretched back. It is a streak that cannot be done. For such a situation, the books of Non-Patent Literature 1-5 and the device of Patent Literature 1 are utilized.

Next, a parallel viewing method (parallel method) and a crossing method (crossing method) will be described with reference to Non-Patent Documents 1-5.
In FIG. 7, in the parallel method (parallel method), the left eye image is viewed simultaneously with the right eye image and the right eye image is viewed simultaneously. The image of can be seen. At this time, the middle image is a combined pseudo-stereoscopic image of the left and right in the brain. In the pseudo-stereoscopic view, the middle part of the image appears to be recessed (sunk).

In FIG. 8, in the cross method (cross method), the image for the right eye is viewed simultaneously with the left eye, and the image for the left eye is viewed simultaneously with the right eye. I can see the image. At this time, the middle image is a combined pseudo-stereoscopic image of the left and right in the brain. In the three-dimensional view, the middle part of the image pops out (floats) and appears.
In the intersection method (cross method), the left and right eye lines intersect in front of the left and right images, and the left and right eyes are close to each other as shown in the dark line drawing in FIG. At this time, the six eye muscles 63, the ciliary body 62, the chin band 65, and the crystalline lens 61 of the eye shown in FIGS. 19-21 are moving.
The present application is an eye force training sheet using a pseudo-stereoscopic image using the parallel method (parallel method) and the cross method (cross method) and a method for using the eye force training sheet, that is, an eye force training method using a printed material and the printed material. explain.

In FIG. 6, in addition to the lower part of FIG. 3, pseudo-stereoscopic images (hypermagical 3D) 7 on page 7-47 of non-patent document 2 and page 20-21 of non-patent document 5 are arranged in parallel downward. indicate. This pseudo-stereoscopic image (Hyper Magical 3D) 7 is a single image, but a black circle mark separated by about 4 cm (average distance between human eyes) is displayed above the image.
If the intersection method (cross) or parallel method (parallel method) is executed consciously, two black circle marks approach each other, overlap in the middle, and a mark appears in the middle, resulting in three marks. Due to the function (visual function) for recognizing a solid provided in the brain, a pseudo-stereoscopic image that is raised (jumped) or sunk (has a depth) from this one image appears.
After viewing a pair of figures as shown in FIG. 3 at the top of FIG. 6, the visual function is accustomed and the pseudo-solid is easily recognized when viewing this single pseudo-stereoscopic image. As a result, so-called hidden characters ABC ..., 123 ..., etc. that could not be seen in the plane image, float or sink and gradually appear. This situation can be used to search for lotteries and prizes. For example, FIG. 6 shows that a picture of “moon” appears.

In FIG. 5, when the images and figures with the parallax described are displayed as the left images 5A, 5B, 5C, and 5D and the right images 6A, 6B, 6C, and 6D that are paired, the pseudo-solid becomes a real solid. I can see.
Therefore, when the cubes and cylinders of FIGS. 1-4 and 6 are images and figures with parallax, a clear pseudo-solid is easily recognized.
The operation of each embodiment will be described.
Now, with the parallel method of FIG. 7 (parallel method: viewing the image for the left eye with the left eye and the image for the right eye with the right eye simultaneously), the movement of the eye corresponding to the right side when observing FIG. First, in the uppermost column, when the left eye 5A is observed with the left eye and the right image 6A is consciously considered for a while, the motor association field 26 in FIG. 10 creates a program for moving both eyes. The program is transmitted to the adjacent rear motor area, and commands to move both eyes from it reach the cervical spinal cord at the upper part of the spinal cord, and the two upper and lower rectus muscles on the outer side of the eyeball in FIG. Move the straight line and the two upper and lower oblique lines so that the left eye is aligned with the left image 5A and the right eye is aligned with the right image 6A. In this parallel method (the parallel method), observers generally need to be trained and practiced, and beginners gradually become accustomed to standing up a blank wall vertically between the left and right eyes and between the left and right images like an aerial photographer. Come.

Furthermore, if the sheet 1 is a newspaper or magazine, the focal point is 40 cm-50 cm in front, so that the ciliary body 62 is automatically contracted as shown in FIG. Then, the chin band 65 is loosened and the crystalline lens 61 is swollen and thick, and the eye is in a state of seeing these nearby images. At this time, the left and right eyeballs are slightly inward but have almost parallel lines of sight, like a pupil indicated by a dotted line on the right of the first row in FIG.
After that, the left and right images in FIG. At this time, the middle image is a combined pseudo-stereoscopic image of the left and right in the brain. In the 3D view, the middle part of the image appears recessed (sunk).

Next, both lines of sight are moved to the second column, blank column left 3B and blank column right 4B in FIG. If the user tries to stare at the left image 5B with the left eye and the right image 6B with the right eye, the motion association field 26 in FIG. 10 similarly creates a program for moving both eyes. In this row, the left image 5B and the right image 6B are separated from each other in the upper row. Therefore, by the same brain function as described above, the two vertical rectus muscles and the two outer and inner straight muscles outside the eyeball in FIG. The straight line (on the left and right sides of the eyeball) and the two upper and lower oblique lines are slightly moved so that the left eye is aligned with the left image 5B and the right eye is aligned with the right image 6B.
At this time, the left and right eyeballs have almost parallel lines of sight from the inward direction as shown on the right in the second row of FIG. 1 (overlapping with the solid line diagram of the crossing method). Further, since the direction of the eyeball changes, the distance from the sheet 1 to be looked at changes slightly, so that the ciliary body 62 and the chin band 65 of FIGS. 20 and 21 move according to the amount of change, and the crystalline lens 61 is deformed. Then, the eye sees these images. After that, due to the action of the brain, the left and right images overlap and a third pseudo-stereoscopic image appears.

Next, the line of sight is moved to the third column, the blank column left 3C and the blank column right 4C. If the next left eye tries to stare at the left image 5C and the right eye 6C with the right eye 6C in mind, the motion association field 26 in FIG. 10 creates a program for moving both eyes. In this row, the left image 5C and the right image 6C are far apart from the adjacent row, so that the brain functions similar to those described above cause the two upper and lower rectus muscles on the outer side of the eyeball and the two inner and outer sides (of the eyeball). The straight line (on the left-right side) and the two vertical oblique lines are slightly moved again so that the left eye is aligned with the left image 5C and the right eye is aligned with the right image 6C.
At this time, the left and right eyeballs look slightly like the pupil shown by the outward line of sight and the dotted line, as shown on the right of the third row in FIG. By changing the direction of the eyeball in this way, the distance from the sheet 1 to be viewed slightly changes, the ciliary body 62 and the chin band 65 move according to the amount of change, and the crystalline lens 61 is deformed, and the eye looks at these images. It will be in the state to see. After that, due to the action of the brain, the left and right images overlap and a third pseudo-stereoscopic image appears.

Next, both lines of sight are moved to the bottom column, the blank column left 3D blank column right 4D. When trying to stare at the left image 5D with the next left eye and the right image 6D with the right eye, the motor association field 26 creates a program to move both eyes. In this row, the left image 5D and the right image 6D are separated from the third row, and therefore, by the same brain function as described above, the two upper and lower rectus muscles and the two outer (inner) The left and right oblique muscles (on the left and right sides) are moved a little further to bring the left eye to the left image 5D and the right eye to the right image 6D.
At this time, the left and right eyeballs are like the pupil shown by the maximum outward line of sight and the dotted line that can be a normal human eye, as shown on the right of the fourth row in FIG. Up to this point, if both eyes are opposite and the line of sight is outward, it is impossible for a normal observer, but it is effective for the exercise of the six muscles around the eyeball. Thus, the direction of the eyeball still changes, so that the distance from the sheet 1 to be looked at changes slightly, and the ciliary body 62 chin band 65 moves according to the amount of change, and the crystalline lens 61 is also deformed, and the eyes Efforts are made to make the image visible.

Next, from this line of sight, if the line of sight is moved from the bottom line to the uppermost field, the blank field left 3A and the blank field right 4A, the left image 5A is viewed with the left eye and the right image 6A is consciously viewed. Then, the motor association field 26 creates a program for moving both eyes. In this first row, the left image 5A and the right image 6A are close to each other, and therefore, by the same brain function as described above, the two vertical straight muscles outside the eyeball and the two inside and outside (on the left and right sides of the eyeball) ) The straight line and the two upper and lower oblique lines move in the direction of returning from the moving position of the maximum span so that the left eye looks at the left image 5A and the right eye looks at the right image 6A. At this time, the left and right eyeballs return to a substantially parallel line of sight, though slightly inward, like a pupil indicated by a dotted line on the right of the first row in FIG. It is easy for the observer to keep the line of sight in this state.
If the observer repeatedly watches the fourth column sequentially from the first column, or conversely the first column sequentially from the fourth column, the movement of the brain function and the six muscles around the eyeball , The movement of the ciliary body 62 and the chin band 65, and the movement of the crystalline lens 61 are repeated.

When getting used to, the observer may return the first column to the fourth column in any order and watch.
At this time, as shown on the right side of FIG. 1, the left and right eye movements gradually move outward from a substantially parallel line of sight toward the outside, and further change to the original direction so that the six muscles around the eyeball are massaged. The distance from the sheet 1 to be looked at changes slightly, and the ciliary body 62 and the chin band 65 move in conjunction with each other according to the amount of change, and the crystalline lens 61 is deformed.
In this way, by changing the line of sight over four columns sequentially or arbitrarily, the eye muscles around the eyeball, the ciliary body 62, the chin band 65, and the crystalline lens inside the face that cannot be manually bitten from the outside. 61 light exercises can be performed.

In FIG. 2, it is the perspective view which entered the number in one cube. The white circle of the left image 5A in the blank column left 3A and the number 1 of the right image 6A in the blank column right 4A are overlapped by the action of the brain, and the third pseudo stereoscopic image with the number 1 appears. In this case, one number is visible to both eyes, which is optimal for brain function training, and the observer can recognize the motor association area 26 and the visual area 19. It is easy for a familiar observer.
In the second column, the white circle of the left image 5B in the left column 3B and the right image 6B of the right column 4B in the blank column 4B overlap the number 2 by the action of the brain, and the third pseudo-stereoscopic image with the number 2 appears. . Even a familiar observer needs effort.

In the third column, the white circle of the left image 5C in the left column 3C and the right image 6C of the right column 4C in the blank column 4C overlap with the number 3 by the action of the brain, and the third pseudo-stereoscopic image with the number 3 appears. . Even a familiar observer may find it somewhat difficult and sometimes the pseudo-stereoscopic images appear separated. However, light movements of the eye muscle, ciliary body 62, chin band 65, and lens 61 are performed.
The white circle of the left image 5D in the left blank field 3D and the right image 6D number 4 in the blank field right 4D overlap by the action of the brain, and the third pseudo-stereoscopic image with the number 4 can be seen. . It is not easy for most observers who are used to it, and most people see it as four images, two on each side. Still, movements of the eye muscles, ciliary body 62, chin strip 65, and lens 61 have been tried.

FIG. 3 is a perspective view in which numbers are entered on both cubes. The number 1 in the left image 5A and the number 1 in the right image 6A are overlapped by the action of the brain, and a third pseudo-stereoscopic image with the number 1 appears. It is easy for a familiar observer.
In the second column, the number 2 of the left image 5B and the number 2 of the right image 6B are overlapped by the action of the brain, and the third pseudo-stereoscopic image with the number 2 appears. Even a familiar observer needs effort.
In the third column, the number 3 of the left image 5C and the number 3 of the right image 6C are overlapped by the action of the brain, and the third pseudo-stereoscopic image with the number 3 is visible. Even a familiar observer may find it somewhat difficult and sometimes the pseudo-stereoscopic images appear separated. However, light movements of the eye muscle, ciliary body 62, chin band 65, and lens 61 are performed.
The number 4 of the left image 5D and the number 4 of the right image 6D in the bottom column are overlapped by the action of the brain, and a third pseudo-stereoscopic image with the number 4 appears. It is not easy for most observers who are used to it, and most people see it as four images, two on each side. Still, movements of the eye muscles, ciliary body 62, chin strip 65, and lens 61 have been tried.
The Still, movements of the eye muscles, ciliary body 62, chin strip 65, and lens 61 have been tried.

FIG. 4 is a perspective view of the smallest cylinder. The cylinder of the left image 5A and the cylinder of the right image 6A are overlapped by the action of the brain, and the third pseudo-stereoscopic image cylinder (shown on the right side) appears. It is easy for a familiar observer.
The second column is a perspective view of a slightly larger cylinder. The cylinder of the left image 5A and the cylinder of the right image 6A are overlapped by the action of the brain, and a slightly larger cylinder of the third pseudo stereoscopic image (shown on the right side) appears. Even a familiar observer needs effort.
The third column is a perspective view of a large cylinder. The cylinder of the left image 5A and the cylinder of the right image 6A are overlapped by the action of the brain, and a third cylinder with a large pseudo-stereoscopic image (shown on the right side) appears. Even a familiar observer may find it somewhat difficult and sometimes the pseudo-stereoscopic images appear separated. However, light movements of the eye muscle, ciliary body 62, chin band 65, and lens 61 are performed.
The fourth column is a perspective view of the largest cylinder. The cylinder of the left image 5A and the cylinder of the right image 6A are overlapped by the action of the brain, and a third cylinder with a large pseudo-stereoscopic image (shown on the right side) appears. Pseudo-stereoscopic images appear to be separated even by a familiar observer. However, light movements of the eye muscle, ciliary body 62, chin band 65, and lens 61 are performed. The cylinder of the pseudo-stereoscopic image (shown on the right side) gradually becomes larger (smaller), and the eye movement and focus adjustment are executed along with the brain activity.

FIG. 5 is a landscape photograph with left and right parallax by a stereo camera. Since the fourth column is closest, a stereoscopic view can be easily prepared. Since the second, third, and fourth columns are separated from the left and right photographs, stereoscopic viewing becomes increasingly difficult, but eye movement and focus adjustment are performed along with brain activity while enjoying the scenery.
In FIG. 6, after getting accustomed to eye movement and focus adjustment along with brain activity, looking at the pseudo-stereoscopic image (Hyper Magical 3D) 7, the brain is ready to be received, so the stereoscopic image can be recognized unexpectedly. .

Next, the crossing method of FIG. 8 (crossing method: viewing the image for the right eye with the left eye and the image for the left eye with the right eye simultaneously), and the movement of the eye corresponding to the right side when observing FIG. It explains together.
First, in the uppermost column, when looking at the left image 5A with the right eye and the right image 6A with the left eye for a while, the motor association field 26 in FIG. 10 creates a program for moving both eyes. The program is transmitted to the adjacent rear motor area, and commands to move both eyes from it reach the cervical spinal cord at the upper part of the spinal cord, and the two upper and lower rectus muscles on the outer side of the eyeball in FIG. Move the straight line and the two upper and lower oblique lines so that the left eye is aligned with the left image 5A and the right eye is aligned with the right image 6A.
In the case of newspapers and magazines, the focal point is 40 cm-50 cm in front, so as shown in FIG. 21, the ciliary body 62 is automatically contracted even if the motor association area 26 in FIG. 65 is loosened, and the crystalline lens 61 is swollen and thick, and the eye is in a state of seeing these nearby images. At this time, the left and right eyeballs have almost parallel lines of sight, as shown by the solid line on the right of the first line in FIG.
After that, the left and right images in FIG. At this time, the middle image is a combined pseudo-stereoscopic image of the left and right in the brain. In the 3D view, the middle part of the image pops out (floats) and appears.

Next, in the second column of FIG. 1, when trying to stare at the left image 5B with the right eye and the right image 6B with the left eye, the motor association field 26 in FIG. 10 creates a program for moving both eyes. In this row, the left image 5B and the right image 6B are separated from each other in the upper row. Therefore, by the same brain function as described above, the two vertical rectus muscles and the two outer and inner straight muscles outside the eyeball in FIG. Slightly move the straight line (on the left and right sides of the eyeball) and the two vertical oblique lines so that the right eye looks at the left image 5B and the left eye looks at the right image 6B.
At this time, the left and right eyeballs still have substantially parallel lines of sight as shown in the right side of the second row in FIG. 1 (the crossing method is a solid line diagram). Further, since the direction of the eyeball changes, the distance from the sheet 1 to be looked at changes slightly, so that the ciliary body 62 and the chin band 65 of FIGS. 20 and 21 move according to the amount of change, and the crystalline lens 61 is deformed. And your eyes will see these images

Next, in the third column, when trying to stare at the left image 5C with the right eye and the right image 6C with the left eye, the motion association field 26 in FIG. 10 creates a program for moving both eyes. In this row, the left image 5C and the right image 6C are far apart from the adjacent row, so that the brain functions similar to those described above cause the two upper and lower rectus muscles on the outer side of the eyeball and the two inner and outer sides (of the eyeball). The straight line (on the left-right side) and the two upper and lower oblique lines are slightly moved again so that the right eye is aligned with the left image 5C and the left eye is aligned with the right image 6C.
At this time, the left and right eyeballs are slightly inward-looking, as shown in the right of the third row in FIG. By changing the direction of the eyeball in this way, the distance from the sheet 1 to be viewed slightly changes, the ciliary body 62 and the chin band 65 move according to the amount of change, and the crystalline lens 61 is deformed, and the eye looks at these images. It will be in the state to see.

Next, when trying to stare at the left column 5D with the right eye and the right image 6D with the left eye, the motor association field 26 creates a program to move both eyes. In this row, the left image 5D and the right image 6D are separated from the third row, and therefore, by the same brain function as described above, the two upper and lower rectus muscles and the two outer (inner) The left and right oblique lines (on the left and right sides) are moved slightly further to bring the right eye to the left image 5D and the left eye to the right image 6D.
At this time, the left and right eyeballs are like the maximum inward line of sight that a normal human eye can see, as shown by the solid line, as shown on the right in the fourth row of FIG. So far, when both eyes are inwardly looking (cross-eyed), it is impossible for a normal observer, but it is effective for the exercise of six muscles around the eyeball. Thus, the direction of the eyeball still changes, so that the distance from the sheet 1 to be looked at changes slightly, and the ciliary body 62 chin band 65 moves according to the amount of change, and the crystalline lens 61 is also deformed, and the eyes Efforts are made to make the image visible.

Again, from this line of sight, if you move both lines of sight from the bottom column to the top column, the blank column left 3A and the blank column right 4A, let's look at the left image 5A with the right eye and the right image 6A with the left eye. Then, the motor association field 26 creates a program for moving both eyes. In this first row, the left image 5A and the right image 6A are close to each other, and therefore, by the same brain function as described above, the two vertical straight muscles outside the eyeball and the two inside and outside (on the left and right sides of the eyeball) ) The straight line and the two upper and lower oblique lines move in a direction returning from the moving position of the minimum span, and the right eye is aligned with the left image 5A and the left eye is aligned with the right image 6A. At this time, the left and right eyeballs return to a substantially parallel line of sight, like a pupil indicated by a solid line on the right of the first row in FIG. It is easy for the observer to keep the line of sight in this state.
If the observer repeatedly watches the fourth column sequentially from the first column, or conversely the first column sequentially from the fourth column, the movement of the brain function and the six muscles around the eyeball , The movement of the ciliary body 62 and the chin band 65, and the movement of the crystalline lens 61 are repeated.
