Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binocular vision training device, for example, a binocular vision training device suitable for use in strabismus correction training and the like.

[0002]

2. Description of the Related Art With the miniaturization of image display devices, head-mounted image display devices (Head Mounted Disp.
A visual function training device (a visual acuity training device and a binocular visual function training device) to which a small-sized display device such as a lay) is applied is devised. The applicant previously applied for a binocular vision function training device (Japanese Patent Application No. 7-39143). This is to enable a patient to enjoy training by displaying a moving image as a training index.

When a healthy person looks at a predetermined object, the lines of sight of both eyes coincide on the object. However, in the case of the strabismus, only the normal line of sight of one eye (normal eye) fixes the target, and the line of sight of the other eye (affected eye) deviates from the target.

As described above, in the case of the strabismus, the line of sight of one eye deviates from the object, so that the brain cannot fuse the retinal images formed on the retinas of both eyes.
Therefore, so-called “double vision” in which two images formed in each of both eyes are recognized separately, or only an object imaged in the retina of a healthy eye is recognized in the brain, and the retina of the affected eye is recognized. The so-called "inhibition" state occurs in which the image formed on is disappeared (erased).

When suppression occurs, the suppressed eye (affected eye) is no longer used, and the visual acuity of the affected eye decreases. It is said that it is important to perform strabismus correction at an early stage, because if this state is left as it is, the visual acuity may be deteriorated and eventually the visual acuity may be difficult to recover.

[0006]

However, if the same target is repeated many times with the same movement even in one training, the concentration (heat intensity) may decrease. was there.

[0007] In the case of a strabismus patient who is partially "suppressed" in which visual information in the affected eye is not perceived by the brain, some optotypes may become invisible during training. For example, when the target for the affected eye moves from the outside of the field of view to the inside of the affected eye, the target becomes invisible when the target moves inward from a predetermined angle. That is, the suppression is applied and the visual target cannot be perceived. In that case, there is a problem that it is difficult to accurately recognize where the target disappears.

The present invention has been made in view of such a situation, and it is possible to suppress the tiredness of the training and to enjoy the training while maintaining the concentration, and even when the restriction is exerted, the training is easily performed. It is possible to grasp the achievement level of.

Next, the operation will be described. First, a case of performing suppression removal training by the vibration method will be described using this embodiment. The trainee first sets the training mode setting unit 21.
Is used to input whether the patient's inhibition eye is on the left or right. Next, the training method to be performed, the size of the target, the squint angle, and the presence or absence of blinking of the target are set. When blinking the target, set the blinking time and blinking interval. Further, the luminance of the target, the movement of the target, that is, the moving range and moving speed of the target, the number of repetitions of training, and the like are set.

These parameters are: training method, squint eye,
And by setting the minimum information such as squint angle,
Other setting items can be set automatically. Thereby, the operation at the time of setting can be simplified.

Further, the data corresponding to the set values relating to the training once set is supplied to and stored in the training mode storage unit 26 of the training storage unit 22. Therefore, in the case where similar training is performed next time, it is possible to read the set value already stored in the training mode storage unit 26 and perform the predetermined training according to the set value. As a result, the setting operation for training can be further simplified.

Here, when the movement or the position of the target is set by the training mode setting unit 21, the viewing angle indicating which direction the target is displayed, such as left, right, up and down, is centered on the eye of the patient. The method of setting was adopted. This is because the display of the optotypes on the display panels 13a and 13b is
It is finally controlled by the two-dimensional coordinate positions on a and 13b, but in the case of strabismus correction training, it is important in which angle direction the target is displayed from the affected eye.

As described above, the data corresponding to the set value input from the training mode setting unit 21 is temporarily stored in the training mode storage unit 26 of the training storage unit 22, and then the optotype presenting process calculation unit 31. Is supplied to. The optotype presenting process calculation unit 31 reads out the optotypes for, for example, suppression removal training stored in the optotype storage unit 23 of the training storage unit 22 according to the setting values supplied from the training mode storage unit 26.

That is, first, the image data corresponding to a predetermined target for the affected eye, which is stored in advance in the target storage for target eye 24, for example, the image data corresponding to "lion" is read out, and then, Image data corresponding to a predetermined target for a healthy eye, which is stored in advance in the target storage unit for a healthy eye 25, for example, image data corresponding to “a cage” is read.

Next, the optotype presenting processing operation section 31 moves the read image data "lion" and "cage" according to the set values supplied from the training mode storage section 26 (change of display position). ), Predetermined image data is created. This image data is supplied to the image construction unit 35.

In the affected-eye image constructing unit 36 of the image constructing unit 35, the optotype corresponding to the image data supplied from the optotype presenting processing unit 31 (in this case, an image of "lion").
However, a predetermined one image signal is constructed so that it is displayed at the designated position on the display panel 13a or 13b. Similarly, in the healthy-eye image constructing unit 37, the optotype (the image of the “cage” in this case) corresponding to the image data supplied from the optotype presenting process calculating unit 31 is designated on the display panel 13a or 13b. A predetermined piece of image data is constructed so as to be displayed at the designated position.

The image data constructed in this way is
In the display panel control unit 38, the left and right display panels 13
Allocation processing and the like are performed on a and 13b. For example, the “lion” that is an image for the affected eye is displayed on the display panel 13 for the right eye.
“Cage” which is displayed in b and is an image for normal eyes is displayed on the display panel for left eye 13a.

The above-mentioned image data supplied to the image construction unit 35 is supplied from the optotype presenting processing unit 31 to the display unit 1 via the display panel control unit 38, and the corresponding optotype is displayed. Since the series of processes described above is performed instantaneously, it is possible to display a moving image of the target on the display panels 13a and 13b according to the setting of the trainee.

Therefore, conventionally, the trainee manually operates the lens barrel of the large-sized amblyopia to move the target by a few degrees around the oblique angle, or while maintaining a constant oblique angle,
The optotype was moved to the left or right, or the optotype was moved to the up, down, left, or right.
A moving image can be displayed by instantly changing the positions of the optotypes displayed on 3a and 13b. Therefore, the optotypes can be moved to the left or right by a predetermined angle around the oblique angle,
Limit the angle at which the target is moved left and right, move the target vertically and horizontally at a constant angular velocity, or move the target left and right or keep blinking while keeping the squint angle constant. Can be done easily.

The optotype displayed on the display unit 1 can be moved by the patient operating the patient input device 11. The operation of the above embodiment in this case will be described by taking the "suppression removal training / chasing method" using "butterflies" and "nets" as targets.

First, the trainee sets the suppression eye to, for example, "right" by the training mode setting unit 21 and sets the "suppression removal / chase method" as the training method. Next, the size of the target is set, and further the training time and other necessary parameters are set. When the training mode setting unit 21 finishes setting the predetermined parameters, the data corresponding to the set parameters is supplied to the training mode storage unit 26, stored therein, and supplied to the optotype presenting process calculation unit 31. It

When predetermined data corresponding to the parameters set by the training mode setting unit 21 is supplied to the optotype presenting process calculation unit 31, the optotype presenting process operation unit 31 firstly outputs the optotype presenting unit 23. The image data corresponding to the "butterfly" as the target for the healthy eye is read from the target storage unit 25 for the healthy eye. Next, the image data corresponding to the "net" as the target for the affected eye is read from the target storage for target eye 24.

The image data corresponding to each of the "butterflies" and the "nets" read out by the optotype presenting processing unit 31 is then subjected to a predetermined optotype presenting process operation. That is, when the corresponding image data is processed and the “butterfly” is displayed on the display unit 1 in order to convert the size, brightness, etc. of the “butterfly” into a predetermined size or brightness value. ,
In order for the movement of the "butterflies" to be continuous and random,
For example, control data for controlling the display of "butterfly" is programmed.

Next, the image data corresponding to the "butterfly" processed by the optotype presenting processing unit 31 and the control data are supplied to the healthy eye image constructing unit 37, for example, the display of the built-in memory is displayed. An image corresponding to each image as a source of a predetermined moving image in a form of being copied to an address corresponding to a predetermined position determined based on the control data of the left-eye display panel 13a of the unit 1. The data is constructed respectively.

On the other hand, the image data corresponding to the “net” read out as the target for the affected eye from the target storage unit 24 for the affected eye by the target presenting calculation unit 31 is the target presenting process calculation. In the unit 31, the size, brightness, etc. of the "mesh" image is processed to convert it into a predetermined size or brightness value.
In addition, the predetermined movement information input by the patient using the joystick 12 provided in the patient input device 11 connected to the patient input unit 42 is displayed as “mesh” on the display panel 13b for the right eye of the display unit 1. Is converted into change information of the display position of and is supplied to the optotype presenting process calculation unit 31.

The optotype presenting / processing unit 31 displays the image data corresponding to the "mesh" on the basis of the change information of the display position of the "mesh" on the display panel 13b for the right eye.
Control data for instructing the display position on b is created and supplied to the image construction unit 35.

In the image construction unit 35, the image data to be displayed on the right eye display panel 13b is stored on the basis of the image data corresponding to the predetermined optotype supplied from the optotype presenting processing unit 31 and the control data. Be built. as a result,
Corresponding to the operation of the joystick 12 by the patient,
The "net" is displayed at a predetermined position on the display panel 13b. That is, the optotype is controlled to move according to the patient's instruction.

In this way, the patient sees the "butterfly", which is the target for randomly moving healthy eyes displayed on the display panel 13a for the left eye, and the patient displayed on the display panel 13b for the right eye. By operating the joystick 12 and moving the "net" toward the "butterfly" so that the movable "nets", which are the visual targets for the eyes, can be seen to overlap, it is possible to perform training as if playing a game. it can.

Further, the optotype presenting process calculating section 31 is provided with a comparing section 32, and a predetermined information inputted from the patient input section 42, for example, display of "net" displayed on the display panel 13b. Data corresponding to position and display panel 1
Comparison with the data corresponding to the display position of the "butterfly" displayed on 3a can be performed.

Therefore, when the "net" catches the "butterfly" by the effort of the patient, the fact is recognized by the comparison unit 32, and for example, a predetermined voice is output to the voice control unit 43. A control signal indicating is supplied. The voice control unit 43 reads out predetermined voice data from the voice signal storage unit 30 according to the control signal supplied from the comparison unit 32, and outputs it to the voice output unit 46.

Alternatively, when the "net" catches the "butterfly" by the effort of the patient, the comparing section 32 recognizes this, and instructs the display panel control section 38 to display the display panel 1.
It is also possible to instruct to change the background colors of 3a and 13b. The display panel control unit 38 includes the comparison unit 32.
The background color of the display panels 13a and 13b is changed in accordance with the command from.

This allows the patient to be aware that the goal of this exercise of overlaying a "net" on a "butterfly" has been achieved.

During the training, the display panels 13a and 13b are also provided.
When the target displayed above moves, the affected eye (in this case, the right eye) of the patient is suppressed, and when the target disappears (becomes invisible), at that point, the patient , By pressing a predetermined button of the patient input unit 42, it corresponds to a visual angle (a target angle (an angle between the front direction of the patient and the line connecting the image and the eyeball of the patient)) at that time. The data can be stored in the training result storage unit 28. Alternatively, the data corresponding to the visual angle at that time may be supplied to the voice control unit 43, and a predetermined voice corresponding to the visual angle may be output to the voice output unit 46 to be transmitted to the patient, the trainee, or the doctor.

Therefore, by reading out and referring to the data stored in the training result storage unit 28, the patient, trainee, and doctor can compare and examine the results of daily training.

When the training result storage unit 28 stores data such as a predetermined training result, the training mode setting,
Based on the date and time measured by the clock 29, the outline of the training setting such as the set value of the training and the training determination result may be stored in association with the training implementation time, the implementation time, and the implementation date and time. it can.

Therefore, by comparing and referring to these pieces of information stored in the training result storage unit 28, the trainee, the doctor, and the patient themselves can confirm the validity of the training including the effect of the training, the progress of the training, or Be able to recognize the results of training over time.

Further, as the simultaneous vision training, for example, a picture showing two human beings is presented to the patient's normal eye, and three human beings are presented to the affected eye (the above-mentioned two and one other person). Present a picture of the. Then, the patient input device 11 causes the patient to input the perceived number of people. Then, the optotype presenting process calculation unit 31 determines whether or not the answer is correct, and if the answer is correct, the audio output unit 46 is caused to output a predetermined audio. In this way, the patient can be trained like a game.

In this example, the target for the affected eye is an image of "lion" or "net" regardless of the presentation angle, but the design of the target is changed according to the presentation angle of the target. Can be allowed to. For example, as shown in FIG. 4, when the optotype presenting angle is around 10 degrees outward, "mouse", when the optotype presenting angle is around 5 degrees "cow", when the optotype presenting angle is around 0 degree It is possible to display "Tora" (when it is almost in front), "Rabbit" when the target presentation angle is about 5 degrees inward, and "Tatsu" when the target presentation angle is about 10 degrees inward. .

Thus, for example, even in the case of a strabismus in which a part of the visual field is "suppressed" in which the visual information of the affected eye is not perceived by the brain, it is possible to easily recognize which target has been perceived. Therefore, the degree of progress of the training can be grasped by the trainee such as the patient himself / herself and the doctor.

For example, when the target of the affected eye moving from the outside to the inside of the visual field is inside a predetermined angle,
When the target of the affected eye becomes invisible (cannot be perceived / suppressed), it is difficult to know where the target disappears. Therefore, for example, a picture of an animal in the zodiac is displayed on the display panels 13a and 13b as a visual target, and the picture to be displayed is referred to as a "mouse" in response to a change in the visual target presentation angle on the display panel. Change it to "cow", "tiger", "rabbit", "dragon", etc.

That is, when the training mode setting unit 21 inputs a set value such as the movement of the target in advance and the data corresponding to the set value is stored in the training mode storage unit 26, the target presenting processing unit 31 is a training mode storage unit 2
6 based on the data stored in the display panel 13
The angles of the optotypes displayed on a and 13b are set. Next, the target data corresponding to this angle is read from the affected eye target storage unit 24 and supplied to the image construction unit 35.

The image constructing unit 36 for the affected eye of the image constructing unit 35
Constructs an image for the affected eye from the optotype data supplied from the optotype presenting processing unit 31, and outputs the corresponding image data to the display panel control unit 38. Display panel control unit 3
When the left eye of the patient is the affected eye and the right eye of the patient is the healthy eye, 8 supplies the image data supplied from the affected-eye image construction unit 36 to the display panel 13a for the left eye of the display unit 1. . When the right eye of the patient is the affected eye and the left eye is the healthy eye, the image data supplied from the affected-eye image constructing unit 36 is supplied to the display panel 13b for the right eye of the display unit 1. As a result, a predetermined target for the affected eye is displayed on the display panel 13a or 13b at a predetermined target angle.

Similarly, the display panel 13a or 13
In b, according to the set value stored in the training mode storage unit 26, the optotype corresponding to the angle is displayed at the next optotype presenting angle. As a result, the visual target is displayed on the display panels 13a, 1
As it moves on 3b, the picture displayed as the optotype changes according to the optotype presenting angle.

Therefore, the patient can be aware of the degree of achievement of the training by recognizing which picture is visible while following the visual target with the eyes. For example, when the "rabbit" can be seen, it can be recognized that the angle has not been suppressed up to the angle corresponding to the "rabbit". Similarly, "Tatsu"
When you see up to, you can recognize that there was no restraint up to the angle corresponding to "Tatsu". That is, it is possible to perform feedback-type training in which the results of the training are fed back to the patient himself.

Here, the zodiac animals corresponding to the target presentation angle are displayed as the target, but as shown in FIG. 4, the size corresponding to the target presentation angle is set as the target. It is possible to display the predetermined figures and pictures that it has,
Alternatively, it is possible to change the color of the optotype in correspondence with the optotype presenting angle.

When the patient operates the patient input device 11, the display panel 13a or 13b of the display unit 1 is operated.
It is also possible to move the optotype displayed on the screen. Patient input device 1 in which a patient is connected to a patient input unit 42
When the joystick 12 of No. 1 is operated, predetermined data corresponding to this operation is converted into change information of the display position of the optotype on the display panel 13a of the display unit 1 in the patient input unit 42, and the optotype presenting process calculation is performed. Is supplied to the section 31.

In the optotype presenting processing unit 31, a control for instructing the display position of the optotype on the display panel 13a or 13b based on the change information of the display position of the optotype on the display panel 13a or 13b for the right eye. Data is created and supplied to the image construction unit 35. Image construction unit 3
In 5, the image data corresponding to the predetermined optotype supplied from the optotype presenting / processing unit 31 is constructed. As a result, in response to the operation of the joystick 12 by the patient, a predetermined optotype corresponding to the optotype presenting angle designated by the joystick 12 is displayed at a predetermined position on the display panel 13a or 13b. That is, the optotype is controlled to move in accordance with the patient's instruction.

In this way, the patient can display the display panel 13
The target such as the picture or figure as shown in FIG. 4 can be displayed on a or 13b while changing the type, size, or color of the picture according to the presentation angle.

Thus, the patient can perform training at his own pace while changing the presentation angle of the optotype. When restraint is applied, as described above, the patient himself / herself can easily recognize the degree of achievement of training depending on which animal of the zodiac animals is visible. In addition, by changing the size and color of the target according to the target presentation angle, it is possible for the patient to easily recognize the degree of achievement of training depending on the size or color of the target. Is.

As described above, even when the joystick 12 is used to move the optotype, as in the case where the movement of the optotype is preset by the training mode setting unit 21, the patient follows the optotype with the eyes. By recognizing which picture you can see, you can be aware of the achievement level of the training. For example, when the "rabbit" can be seen, it can be recognized that the angle has not been suppressed up to the angle corresponding to the "rabbit". Similarly, when "Tatsu" is visible, it is possible to recognize that the angle corresponding to "Tatsu" was not suppressed. That is, it is possible to perform feedback-type training in which the results of the training are fed back to the patient himself.

Next, a case will be described in which the optotype for the affected eye is displayed on the display panel 13a and a predetermined sound corresponding to the optotype presenting angle is output from the audio output unit 46. In this case, it is assumed that the patient's affected eye is the left eye.

When a set value such as the movement of the optotype is input in the training mode setting section 21 beforehand and data corresponding to the set value is stored in the training mode storage section 26, the optotype presenting processing section 31 The angle of the optotype displayed on the display panel 13a is set based on the data stored in the training mode storage unit 26. Next, the training mode storage unit 26
Data of the optotype corresponding to this angle is read from the optotype memory unit for an affected eye 24 stored in the table, and is supplied to the image construction unit 35.

The image constructing unit 36 for the affected eye of the image constructing unit 35
Constructs an image for the affected eye from the optotype data supplied from the optotype presenting processing unit 31, and outputs the corresponding image data to the display panel control unit 38. Display panel control unit 3
In this case, since the left eye of the patient is the affected eye and the right eye is the healthy eye in this case, the image data supplied from the affected-eye image constructing unit 36 is displayed on the display panel 13a for the left eye of the display unit 1. Supply to. As a result, a predetermined target for the affected eye is displayed on the display panel 13a at a predetermined target angle.

Similarly, according to the set value stored in the training mode storage unit 26, the display target corresponding to the angle of the next target display angle is displayed on the display panel 13a. As a result, as the optotype moves on the display panel 13a, the type of picture displayed as the optotype changes corresponding to the optotype presenting angle.

On the other hand, the optotype presenting processing operation section 31 supplies a predetermined control signal corresponding to the presenting angle of the optotype displayed on the display panel 13a to the voice control section 43. Voice control unit 43
Uses a predetermined sound signal read from the sound signal storage unit 30 based on this signal using a predetermined function so that the sound source exists in the direction of the target presentation angle, that is, the direction of the target presentation angle. Is processed so that a predetermined sound can be heard and supplied to the audio output unit 46. This signal includes a signal for the left audio output unit 46a and a signal for the right audio output unit 46b.
And a signal to.

The left audio output section 46a includes an audio control section 43.
After amplifying the signal from, the right audio output section 46b amplifies the signal from the audio control section 43, and then outputs the audio of a predetermined volume. For example, when the optotype is displayed outside the display panel 13a, in this case, on the left side of the display panel 13a, as shown in FIG. 5A, a predetermined distance from the eye in the same direction as the optotype presenting angle is displayed. The left audio output unit 46a and the right audio output unit 46b output sounds of a predetermined volume and a predetermined timbre, respectively, so that the sound source is located at a distance.

The output signal from the left audio output section 46a is
The output signal from the right audio output unit 46b is supplied to the speaker 5a attached to the patient's left ear, and is supplied to the speaker 5b attached to the patient's right ear. The volume of the sound output from the speaker 5a is controlled to be larger than the volume of the sound output from the speaker 5b, and the timbre of the sound output from the speaker 5a is output from the speaker 5b. The timbre is controlled so that it sounds closer to the timbre of the sound being played. As a result, the patient is
It is recognized that the sound source exists at the position shown in (a).

Similarly, when the optotype is displayed substantially in front of the patient's left eye (affected eye), the audio control unit 43 outputs the sound source from the sound source in accordance with the control signal from the optotype presenting / processing unit 31. The predetermined voice signal read from the voice signal storage unit 30 is processed by a predetermined function so that the predetermined voice can be heard almost from the front of the affected eye, and then is supplied to the voice output unit 46. The left audio output unit 46a and the right audio output unit 46b of the audio output unit 46 amplify the signal from the audio control unit 43 and then supply the amplified signals to the speakers 5a and 5b, respectively. As a result, the volume of the sound output from the speaker 5a becomes slightly larger than the volume of the sound output from the speaker 5b, and the timbre is such that the sound from the speaker 5a is felt closer to the sound from the speaker 5b. Then, the patient recognizes that the sound source is almost in front of the left eye, as shown in FIG.

Similarly, when the optotype is displayed inside the left eye (affected eye) of the patient, the optotype presenting / processing unit 31
According to the control signal from the sound control unit 43, the sound control unit 43 processes the predetermined sound signal read from the sound signal storage unit 30 by a predetermined function so that the predetermined sound from the sound source can be heard from the inside of the affected eye. It is supplied to the output unit 46. The left audio output unit 46a and the right audio output unit 46b of the audio output unit 46, after amplifying the signal from the audio control unit 43,
It is supplied to the speakers 5a and 5b, respectively. As a result, the loudness of the voice output from the speaker 5a becomes substantially the same as the loudness of the voice output from the speaker 5b, and all the tones become tones that can be felt at an equal distance. As shown in (c), the sound source is recognized as being inside the left eye.

As described above, the sound source is present at a predetermined position in the direction corresponding to the optotype presenting angle by adjusting the loudness and the tone color of the sounds output from the left and right speakers 5a and 5b, respectively. By constructing the sound field, the patient can perceive the sound field in virtual reality,
The position on the display panel 13a where the optotype is displayed (the optotype presenting angle) can be recognized by voice. Therefore, even if the optotype moves from the outside to the inside and the eye of the patient is suppressed at a predetermined optotype presenting angle,
Since the patient can hear the sound from the direction corresponding to the optotype presenting angle, the patient can recognize at which optotype presenting angle the suppression is applied.

As a result, the patient himself / herself and the training supervisor such as a doctor can grasp the progress of the training by being aware of what sound field the patient can perceive before the suppression is applied. . In addition, even if the target is no longer visible due to the suppression of the patient's eyes, the position of the sound source, that is, the sound field, changes according to the motion of the target, so the patient should be aware that the target is actually moving. Can be informed.

In the above embodiment, the left and right speakers 5
Sounds of different sizes and timbres are output from a and 5b so that the sound source exists at a predetermined position in the direction corresponding to the target presentation angle. It is possible to output only the same sound of a predetermined timbre from the speakers 5a and 5b. In this case, since it is not necessary to form a stereo sound, the sound may be output from only one of the left and right speakers.

That is, the optotype presenting processing operation section 31 generates a predetermined control signal for instructing to output a tone color corresponding to the optotype presenting angle, and supplies it to the voice control section 43. The voice control unit 43 reads out a voice of a predetermined tone color from the voice signal storage unit 30 based on the control signal from the optotype presenting process calculation unit 31, and supplies the voice output unit 46 with the voice. As a result, an audio signal corresponding to a predetermined timbre is output from the left audio output unit 46a and the right audio output unit 46b of the audio output unit 46. This audio signal is generated by the speakers 5a and 5
b, and the sound of the corresponding tone color is output.

In this way, by changing the timbre of the voices output from the left and right speakers 5a and 5b in accordance with the target presentation angle, the patient can display the target on the display panel 13a. Position (target presentation angle) changes in timbre (for example, changes in sound frequency, changes in sound interval, etc.)
Can be recognized by. Therefore, the optotype moves from the outside to the inside, and at a predetermined optotype presenting angle, even if the patient's eye is suppressed, the patient can hear the sound of the tone color corresponding to the optotype presenting angle.
The patient can recognize at which target presentation angle the suppression is applied.

As a result, it is possible for the patient himself / herself and the training supervisor such as a doctor to grasp the progress of the training by being aware of what tone color the patient could perceive before the suppression was applied. it can. Further, even when the optotype is suppressed by the patient's eye and the optotype cannot be seen, the timbre changes in accordance with the movement of the optotype, so that the patient can be informed that the optotype is actually moving.

Further, by changing the loudness and tone color of the voices output from the left and right speakers 5a, 5b in accordance with the optotype presenting angle, the position of the sound source is changed and the tone color of the voice is changed. It is also possible to do so.

Even when the patient himself operates the joystick 12 to move the target, it is possible to recognize the position of the target by the sound field and tone of the voice in the same manner as described above. it can. In addition, even if the target is invisible due to the suppression of the patient's eyes, the sound field and timbre change according to the movement of the target, so inform the patient that the target is actually moving. You can

Next, the "usage guide function" provided so that the patient can train alone will be briefly described. The "use guide function" is for explaining and motivating the training of the patient.
