Description

The present invention relates to a visual acuity training tool.

Conventionally, a device for training visual acuity has been proposed. In the training device, "a training device for dynamic visual acuity, characterized in that the light emitting portion (16) is formed in a rod shape so that light emission can be seen from the side surface" has been proposed.

Japanese Unexamined Patent Publication No. 2005-160971

Although the above-mentioned dynamic visual acuity training device has an effect of improving visibility from the side of the light emitting portion, it is inconvenient because the operation is complicated and the trainee cannot operate it by himself / herself. Also, since you only follow the point-shaped light emitting part, you will soon get bored with monotonous training.

On the other hand, as the population ages, the need for training to improve the eyesight of the elderly is being said. The dynamic visual acuity, which was around 0.8 at the peak around 20 years old, gradually began to decline, and decreased sharply from the 40s on average, and the dynamic visual acuity of people over 70 years old was 0. It is said that it has dropped to around 1. In addition, the viewing angle is said to be about 200 degrees for general adults and about 160 degrees for elderly people, and it is said that peripheral visual function declines with aging. However, the above training device is not suitable for the elderly.

In addition, it is said that a state that is difficult to recognize even if it is visible is caused by psychological factors or unconscious selection of the brain (scotomas), and training that does not overlook notable objects is required.

The present invention is intended to solve at least one of the above problems, and an object of the present invention is to provide a visual acuity training tool that can be easily operated and used without getting tired.

In order to solve at least one of the above-mentioned problems, the vision training tool according to the present invention is a vision training tool mounted on the head, and the mounting portion and the display area are arranged in front of the eyes. An image display unit mounted on the head by the unit is provided, and the training images of the training image set are sequentially displayed in the display area, and the display of the training image makes the gaze area and the visibility from the gaze area. The non-gaze area is formed, and the training image set includes two or more of one or both of the left eye training image and the right eye training image, and the gaze areas of the left eye training images are different from each other, and the right The gaze areas of the eye training images are different from each other.

In the vision training tool, the training image is sequentially switched in the display area so that the gaze area moves in a predetermined direction, and the training image set is displayed. It may be an oblique direction or a combination of these directions.

In the visual acuity training tool, the training image set may be repeatedly displayed in one training.

In the visual acuity training tool, the non-gaze area may be an area where it is difficult to see the outside view directly through the display area.

In the visual acuity training tool, the non-gaze area may be a partial area that is difficult to see in the external view that is indirectly visually recognized by displaying the training image in the display area.

In the visual acuity training tool, the non-gaze area may be a part of the image displayed in the display area, which is difficult to see. In the visual acuity training tool, a frame line or a figure for enhancement may be displayed around the gaze area in the display area.

In the visual acuity training tool, the switching of the training image may be performed according to the movement of the wearer's head.

According to the present invention, it is possible to provide a visual acuity training tool that can be easily operated and used without getting tired.

However, the inner edge K2 is located inside the outer edge K1. When each training image is displayed, a gaze area M (LM, RM) having an inner edge K2 as an outer edge and a non-gaze area N (LN, RN) between the outer edge K1 and the inner edge K2 are formed in the display area. .. In the following, for convenience of explanation, the region inside the inner edge K2 of each training image is also referred to as a gaze region M (LM, RM), and the region between the outer edge K1 and the inner edge K2 is also referred to as a non-gaze region N (LN, RM). It will be explained as.

At least two pairs of training images in the training image set have different gaze areas between the left eye training images and different gaze areas between the right eye training images, more specifically, the positions or sizes of the gaze areas are different from each other. Preferably, the training images in the training image set are sequentially switched and displayed so that the gaze area M moves in a predetermined direction or expands or contracts to a predetermined size.

Here, a training image set 500 for moving a binocular ball in a horizontal direction, for example, from right to left is shown. The training image set for moving the eyeball from left to right can be constructed symmetrically.

The training image set 500 includes two or more pairs of left and right training images. As an example, three pairs of training images of the first training image 501, the second training image 502, and the third training image 503 are included in order. Here, in each training image, the gaze area M is a region where the outside view can be seen through the display area, and the non-gaze area N is a dark color. In the case of the transparent organic EL panel, the training image is displayed when the organic EL element in the region corresponding to the gaze region M is controlled to be OFF and becomes a transparent state, and the non-gaze region N corresponds to the surrounding area. It is displayed when the organic EL element is ON-controlled and emits light in a dark color. Although details are omitted, the image control unit 133 generates and outputs an image signal for displaying the training image display unit 121 in this way.

Here, as a result of displaying the training image set 500 in front of the wearer's eyes, the image visually recognized by the wearer is shown by taking the left eye as an example. As shown in the figure, by displaying the training image set 500, the visibility of the external view visually recognized by the wearer is partially changed, the gaze area LM and the non-gaze area LN are formed, and the visibility of the non-gaze area N is formed. Is declining. Here, it can be said that the training image is a visibility change image that changes the visibility of the outside view that the wearer directly sees through the display area.

As shown in the image 601L, as a result of displaying the left eye training image 501L to the left eye, the left eye can see the person on the right side through the gaze area with respect to the outside view where two people play ball games. ing. Next, as shown in the image 602L, as a result of displaying the left eye training image 502L to the left eye, the left eye visually recognizes the racket held by both people in the center with respect to the outside view where two people play tennis. It is designed to do. Next, as shown in the image 603L, as a result of displaying the left eye training image 503L with respect to the left eye, the left eye can see the person on the left side with respect to the outside view where two people play tennis. ing. In this way, the left eye moved its eyeball so that the line of sight would follow the fluctuation of the gaze area LM.

As described above, the visual acuity training tool 100 can promote a predetermined movement to the wearer's eye by displaying the training image set in front of the wearer's eyes, and can easily realize the training of the eye muscles. Therefore, the dynamic visual acuity can be improved. In addition, since the line of sight extends over a wide range due to the movement of the eye part, it can be used as training for recognition of the brain and can suppress the narrowing of the viewing angle.

When using the visual acuity training tool 100, the wearer operates the operation unit 131 (for example, by pressing the start button) to display the training image set 500, the head does not move, and the gaze area changes in the eye area. Follow. The wearer can stretch the eye part to move the extraocular muscles from side to side simply by repeating this. The training image set 500 may be repeatedly displayed for a predetermined time by one operation. When the stop time is set and one set is displayed, the training image set 500 may be displayed again after stopping for a maximum of several seconds.

The visual acuity training tool 100 can be easily operated in this way. In addition, you can train while looking at the outside scenery, so you can use it comfortably without getting bored.

The second training image 522 includes a left eye training image 512L having the second smallest gaze area LMB and a right eye training image 512R having the second largest gaze area RMB. The third training image 513 includes a left eye training image 523L having the third smallest (maximum) gaze area LMC and a right eye training image 522R having the third largest (minimum) gaze area RMC. It should be noted that the training image is configured symmetrically with the illustration, and the training image in which the gaze area changes sequentially from large to small is displayed for the left eye, and the training image in which the gaze area changes sequentially from small to large is displayed for the right eye. It may be displayed.

FIG. 8 is a diagram for explaining another example of the training image of the visual acuity training tool. FIG. 8A shows a training image set 530 for promoting the movement of the eyeball from diagonally above to diagonally downward. The training image set 530 includes two or more pairs of left and right training images, but here, the first training image is shown, and the fluctuation of the gaze area is shown by a white arrow. As shown in the figure, the training image set 530 displays the gaze area gradually fluctuating from the upper right to the lower left with respect to the left eye, and also gradually fluctuates from the upper right to the lower left with respect to the right eye. indicate.

FIG. 8B shows a training image set 540 for encouraging the movement of the eyeball from diagonally above to diagonally downward. The training image set 540 includes two or more pairs of left and right training images, but here, the first training image is shown, and the fluctuation of the gaze area is shown by a white arrow. As shown, the training image set 540 moves the gaze area from the upper right to the lower left, from there to the lower right, then from there to the upper left, and finally back to the upper right with respect to the left eye. It is displayed in a fluctuating manner. Similarly, the gaze area is varied and displayed for the right eye.

FIG. 8 (c) shows a training image set 540 for encouraging the rotational movement of the eyeball. The training image set 550 contains two or more pairs of left and right training images, but here, the first training image is shown, and the fluctuation of the gaze area is shown by a white arrow. As shown in the figure, the training image set 550 displays the gaze area in a clockwise direction from the upper right with respect to the left eye, and similarly changes and displays the gaze area with respect to the right eye.

By training as shown in FIG. 8, the movement of the six extraocular muscles can be accelerated and the dynamic visual acuity can be improved. The display time of one set of training image sets is preferably selectable according to age. The display time of one set of training image sets is preferably such that the display time can be gradually shortened to raise the training level. For example, the elderly may initially take about 5 seconds, then gradually increase the training level to about 0.5 seconds at the highest level. For young people, it may take about 3 seconds at the beginning, and then gradually increase the training level to about 0.2 seconds at the highest level. A combination of the above training image sets may be regarded as one group, and training may be performed in units of one group. In the training of one group unit, a stop time may be provided between the training image sets, and the display of the training image set and the stop time (for example, 1 second to 6 seconds) may be combined. In the display of one set of training image sets, a stop time may be provided in predetermined units. For example, in the training image set 540 of FIG. 8C, the training image set 540 may be divided into four groups of upper right, lower right, lower left, and upper left, and a stop time may be provided between each group.

The above is an example of the training image set, and the training image set may be a combination of different movements or different movements from the above. Further, it may be displayed repeatedly in a unit different from the above. In addition, it may be linked with brain training by combining with the display of numbers, letters, figures and the like. Further, it may be linked with the movement of a body part other than the head. Here, the body refers to a part other than the head.

FIG. 9 is a diagram for explaining an example of a training image of a visual acuity training tool. Here, the training image further includes a document display, which combines the document display and the visibility change image.

FIG. 9A shows a training image set 560 that displays a horizontally written document with a variable gaze area. FIG. 9B shows a training image set 570 that displays a vertically written document with a variable gaze area. The training image set 560 and the training image set 570 change the gaze area M in the order of A, B, C, D, ... To the end of the document. The training image set 560 and the training image set 570 may include an image displaying the entire document at the beginning or the end. Further, the size of the gaze area is set to 3 lines here, but may be 4 lines or 5 lines.

In the training image set 560 and the training image set 570, when the training image display unit 121 is configured by using the transparent organic EL panel, for example, the organic EL element corresponding to the characters in the gaze area is made to emit white light to gaze. It can be displayed by turning off the organic EL element corresponding to the portion other than the characters in the area and causing the organic EL element corresponding to the non-gaze area to emit light in a dark color.

It is said that the basics of speed reading are to move the eyes quickly and to see the next line or character as one. These factors require eye movement and dynamic visual acuity. And the judgment of the brain on that is required. By repeating the above training, it is expected that the basic ability of speed reading will be acquired.

FIG. 10 is a diagram for explaining an example of a visual acuity training tool linked to the movement of the body. The switching of the training images in the training image set may be performed according to the movement of the wearer's head. Here, an example in which the training image is switched as a result of the movement of the wearer's head is shown using the wearer's visual image as an example of the left eye.

As shown in the image 611L, when the left eye training image 501L is displayed for the left eye and the person on the right side is visually recognized in the gaze area, the head moves to the right as shown by the black arrow. Like the image 612L, the left eye training image 502L in which the gaze area moves to the left is displayed to the left eye so that the line of sight stays on the person on the right side. Next, when the head moves further to the right as shown by the black arrow, the gaze area moves further to the left so that the line of sight stays at the person on the right side, as in the image 613L, and the left eye training image 503L It will be displayed to the left eye. In this way, the training image set may be displayed to train the eye muscles so that the head is moved to continue observing the same object.

FIG. 11 is a diagram for explaining an example of a visual acuity training tool linked to the movement of an object. The visual acuity training tool 100 may further include an object movement detection unit that detects the movement of the object, and may display a training image set in conjunction with the movement of the object. Here, an example in which the training image is switched as a result of following the movement of the object is shown using the visual image of the wearer as an example of the left eye.

As shown in the image 621L, when the left eye training image 501L is displayed with respect to the left eye and the person on the right side is visually recognized in the gaze area, when the ball, which is the object, moves, as in the image 622L. The gaze area moves to the left so as to follow the ball, and the left eye training image 502L is displayed for the left eye. Further, when the ball moves to the left, the gaze area moves further to the left so as to follow the ball, as in the image 623L, and the left eye training image 503L is displayed to the left eye. In this way, the training image set may be displayed to train the eye muscles so as to follow a moving object.

FIG. 12 is a diagram for explaining an example of a visual acuity training tool linked to the movement of an object. In a ball game as shown in the figure, the ball often moves in a curved shape (parabolic shape, etc.), so a training image set in which the gaze area fluctuates in a curved shape is desirable. For example, an image set that fluctuates in a curved shape such as the illustrated image 631L, image 632L, and image 633L may be used.

In each training image, the inner edge K2 may be emphasized in red or the like. The non-gaze area N may be any as long as the visibility is inferior to that of the gaze area M, and the mode is not particularly limited.

Further, the training image set may be performed only on the left eye portion including only the left eye training image, or may be performed only on the right eye portion including only the right eye training image. However, it may be performed alternately for both eyes.

<Modification 1 of Embodiment 1>
The visual acuity training tool 100 of the first embodiment displays the training image set on the training image display unit using the transparent organic EL panel, but may be displayed (presented) to the wearer by another configuration.

As an example, the training image display unit may be configured by using a liquid crystal shutter (optical filter), and the display area may be formed on the liquid crystal shutter. The drive voltage of the liquid crystal shutter changes according to the signal from the image control unit 133, and the light transmittance changes. The configuration of the liquid crystal shutter is not particularly limited, and a known technique is appropriately used.

The gaze area M of each training image in the training image set is displayed when the light transmittance of the area corresponding to that of the liquid crystal shutter is 100%, and the non-gaze area N of each training image corresponds to that of the liquid crystal shutter. It is displayed when the area is opaque or has a low transmittance.

<Embodiment 2>

<Embodiment 5>
The visual acuity training tool of one aspect of the present invention is attached to the wearer's head and displays an object display to train the wearer's visual acuity so as not to overlook a noteworthy object.

As the visual acuity training tool of the present embodiment, for example, the visual acuity training tool of the third embodiment is used, and the target display unit is provided instead of the training image display unit, and the target control unit is provided instead of the training image control unit. In the following, the points different from the above example will be mainly described, and the description of the common points will be omitted as appropriate. The training image display unit and the training image control unit of the above embodiment may be used in common with the functions of the target display unit and the target control unit.

The target control unit acquires an outside view image captured by the image capturing unit and detects an object in the outside view. The target object is registered in the storage unit in advance, and the target control unit determines whether the object in the outside view matches the target object and identifies the object to be noted. The target control unit determines the target display S to be applied to the specified notable target, and causes the target display unit to display an image in which the target display S is superimposed and displayed on the outside view image.

FIG. 23 is a diagram showing an example of a target display of the visual acuity training tool according to the fifth embodiment. As shown in FIG. 23 (a), when training not to overlook a notable object in a ball game, as an example, the opponent's ball and racket are specified as notable objects, and the sizes of the ball and the racket are respectively. The target displays S1 and S2 corresponding to the above are determined and displayed. The target displays S1 and S2 are, for example, square red frames. The target display S2 may include the hand of the opponent holding the racket in the frame. The target displays S1 and S2 are displayed so as to follow the change of the outside view, that is, to follow the movement of the other party. By displaying in this way, the wearer can be trained not to overlook the racket or ball of the opponent who should be noted in the ball game. The color and shape of the object display may be changed according to the object of interest. For example, if the target display S1 of the ball is a round red frame and the target display S2 of the racket is a square yellow frame, it becomes easier for the brain to discriminate the target to be noticed through repeated training.
In addition to the frame line, a figure (arrow, star, dot, circle, multiple circles, etc.) may be displayed.

When hitting a service in a ball game as shown in the figure, it is necessary to determine how to hit the opponent (for example, slice serve, spin service, etc.), and the positional relationship between the ball and the body (for example, the face) can be a guide, so that training. Therefore, an arrow indicating the positional relationship may be added and displayed as the target display S3. By displaying the target in this way, it is possible to train the eyesight so as not to overlook the point for guiding the wearer's line of sight and determining the movement of the other party.

The target control unit may analyze the external view image captured by the image capturing unit, indicate the direction of the target to be noted next by displaying the target with an arrow or the like, and guide the line of sight in that direction. For example, in doubles ball games, if the opponent's avant-garde does not pouch, it is necessary to quickly shift the line of sight to the opponent's rearguard, and if the avant-garde himself does not hit and the rearguard is hit, determine whether the opponent's avant-garde will appear on the pouch. Since it is necessary, early improvement can be expected by conducting training to guide the line of sight by displaying the target.

As shown in FIG. 23B, when the object to be noted is far away, the object control unit may determine a part to be enlarged in the external view image, enlarge the part, and superimpose the part together with the object display. good.

As shown above, in the detection method, for example, a marker is attached to an object in order to detect each object on a ball, a racket, etc., and the direction, position, and type are identified by detecting them. By doing so, it is possible to facilitate more accurate detection.
In addition, it is said that the condition that is difficult to recognize even if it is visible is caused by psychological factors or unconscious selection of the brain (Scotoma), and it can also strengthen training not to overlook notable objects.

The visual acuity training tool of the second embodiment may be used with an image imaging unit, a target display unit instead of the training image display unit, and a target control unit instead of the training image control unit. In this case, the target display is displayed for the external view directly viewed through the display area. The visual acuity training tool of the fourth embodiment may be used with an image imaging unit, a target display unit instead of the training image display unit, and a target control unit instead of the training image control unit.
