[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head-mounted display device for magnifying an image formed by an image display device and visually recognizing it with a single eye, and more particularly to a structure for determining a virtual image visually recognizing eye and a mounting method thereof. .

[0002]

2. Description of the Related Art At present, a head-mounted display device has been proposed in order to meet the demand for enhancing the portability of video and data displays. As a typical example, USP
No. 5, 162, 828, "Virtua
"Vision Vision Sport", a portable head-mounted display device has been commercialized. This is an image formed by one liquid crystal display element, magnified by a lens, and a virtual image with the effective eye of the user. Is configured to be visible.

[0003]

In the above-mentioned monocular head-mounted display device, it is recommended that the virtual image is visually recognized by the effective eye of the user. It is either for the eyes only. However, since each user has different effects, the versatility and commonality are poor. Further, the justification of visually recognizing the virtual image with the dominant eye has not been established yet, and it has been found from the experiments by the applicant described later that visually recognizing the virtual image with the dominant eye is one of the causes of fatigue. Furthermore, the main body of the apparatus does not have a structure for determining the effective eye, which causes the erroneous selection of the virtual image visually recognizing eye.

The present invention is intended to solve the above-described problems, and an object thereof is to allow a user to select a virtual image visual recognition eye, which is excellent in versatility and commonality, and which can be used as a virtual image visual recognition eye. To reduce fatigue as the dominant eye and realize a head-mounted display device and a mounting method of the head-mounted display device that can easily determine the counter-effect eye that is a virtual image visual eye with the device body mounted. is there.

[0005]

In order to solve the above problems, a head mounted display device of the present invention is a virtual image comprising an image display element and a magnifying optical means for magnifying a virtual image of an image formed by the image display element. The forming optical system is stored in the device body,
In a head-mounted display device in which the apparatus main body is mounted on the head to visually recognize an image on either the left or right side of the user, a virtual image forming optical system is movably held in the direction of the eyes of the user for use. Has a switching means for switching and holding the virtual image forming optical system in front of either one of the left and right of the person, the virtual image is visually recognized by the reaction eye of the user by the switching means, and the eye width of the user of the apparatus main body is substantially It is characterized in that it has a counter-effect eye judging means of the user at the central position.

Alternatively, a partially transmissive light-shielding plate having a size that partially covers the visual fields of both eyes is provided outside the virtual image forming optical system as seen from the user, and the partially transmissive light-shielding plate of the user is provided. It is characterized in that it has a counter-effect eye determination means at a substantially central position of the pupil distance.

At this time, it is preferable that the apparatus main body has a mounting means for mounting it on the head of the user, and the apparatus main body is held by the mounting means via a hinge portion which is rotatable in the vertical direction of the user. .

Alternatively, the amount of movement of the virtual image forming optical system in the eye width direction may be equal to or larger than the eye distance of the user.

Further, in the method of mounting the apparatus body, the apparatus body is mounted on the head so that the negative-effect eye determining means can visually recognize it at substantially the center of the visual fields of both eyes of the user, and an image formed by the virtual image forming optical system. And the relative position of the image formed by the counter-effect eye determination unit, or the relative position of the image formed by the external-effect information and the counter-effect eye determination unit, as viewed with both eyes and with one of the left and right eyes Depending on the state, the relative position shift is compared, the eye that was visually recognized when the relative position shift is large is determined to be the reaction eye, and the virtual image forming optical system is moved to the reaction eye side to create a virtual image. It is characterized by visually recognizing.

At that time, between the eyes of the user and the main body of the apparatus, light-shielding means which can be arbitrarily selected between the eyes of the user, both eyes, one eye, and the other eye may be used together.

[0011]

According to the structure of claim 1, since the virtual image forming optical system is movable in the direction of the eye width of the user, it is possible for the user to easily and freely switch the eyes for recognizing the virtual image. Therefore, it is excellent in versatility and commonality. Further, it has been confirmed by experiments by the present applicant that visually recognizing the virtual image with the counter-effect eye reduces fatigue as compared with visually recognizing the virtual image with the effective eye.

In particular, since the reaction-effect eye determination means is provided in the apparatus main body substantially at the center of the eye width of the user, the relative position when the virtual image and the image by the reaction-effect eye determination means are viewed with both eyes, and at that time. It is possible to compare the relative position of the virtual image viewing eye only when viewed monocularly, and it is possible to easily determine the virtual image viewing eye while the apparatus body is mounted.

According to the structure of claim 2, by disposing the partially transmissive light-shielding plate outside the virtual image forming optical system, it is possible to suppress the incidence of external light from the anti-virtual image visually recognizing eye, and thus the virtual image forming optical system. The visual contrast of the virtual image can be improved independently of the movement of the virtual image, and the virtual image can be easily viewed without causing binocular rivalry even with monocular vision.By providing the counter-effect eye determination means on the partially transmissive light-shielding plate, It is possible to easily determine the virtual image visually recognizing eye with the apparatus body attached. Further, the counter-effect eye determining means of claim 2 is farther from the user than the counter-effect eye determining means of claim 1, and is closer to the nearer point to the user, so that it is easier to determine the virtual image visually recognizing eye. Can be done.

According to the third aspect of the invention, since the apparatus main body and the virtual image forming optical system in front of the eye can be moved in the direction of the upper visual field of the user through the hinge portion, it is possible for the eye to visually recognize the counter-effect eye determining means. By the virtual image forming optical system, it is possible to easily move to the position where the blind eye determination means that is in a blind spot can be visually recognized. This makes it possible to easily compare the relative positional deviations in the counter-effect eye determination even with the apparatus main body attached.

According to the structure of claim 4, since the virtual image forming optical system can be moved in the direction of the user's lateral field of view, it is possible to easily perform the counter-effect eye determination as in the operation of claim 3.

According to the fifth and sixth aspects of the invention, it is easy to determine the counter-effect eye which is the virtual image visual recognition eye, and it is possible to avoid erroneous selection of the virtual image visual recognition eye, so that fatigue can be reduced. . In particular, according to the configuration of claim 6, the contraction action of the muscle around the eye generated by crushing one of the left and right eyes in the determination of the counter-effect eye may affect the open eye. It is low, and it is possible to more reliably perform the counter-effect eye determination.

[0017]

Embodiments of the present invention will be described below in detail with reference to the drawings.

(Embodiment 1) FIGS. 1 to 3 show a mounted state of a head-mounted display device in a first embodiment of the present invention, FIG. 1 is a front view, FIG. 2 is a side view, and FIG. FIG. 3 is a vertical sectional view of a virtual image forming optical system. In addition, a part of FIG. 1 is shown in a cross-sectional view for explanation.

In FIGS. 1 and 2, the apparatus main body 1 has a virtual image forming optical system 3 in front of either the left or right side of the eye of the user 2. The virtual image forming optical system 3 is held idle in the apparatus body 1, extends substantially in the eye width direction of the user 2, and is screwed and fitted to a shaft 4 having a screw shape to be held in the apparatus body 1. It has knobs 5 at both ends. In addition, the device body 1 includes a hinge portion 6
Via the forehead pad 7a, the arm 7b, the slider 7c, and the ear pad 7d, and by mounting the mounting means 7 on the head of the user 2, the apparatus main body 1, that is, the virtual image formation. The optical system 3 is held in front of the eyes of the user 2.

In FIG. 3, the virtual image forming optical system 3 includes an image display element 10 including a liquid crystal panel 8 and a backlight 9 for illuminating the liquid crystal panel 8 from behind, a reflection mirror 11, and a lens as a magnifying optical means. It consists of 12. The image light emitted from the image display element 10 has its optical path changed by the reflection mirror 11, and is imaged in the virtual image visual eye 13 of the user 2 by the lens 12. At this time, by arranging the image forming surface of the image display element 10 on the lens 12 side with respect to the object side focus of the lens 12, and arranging the virtual image visualizing eye 13 near the image side focus of the lens 12, the image formation of the lens 12 is performed. By the action, the enlarged virtual image 15 of the screen information can be visually recognized on the extension line of the optical axis 14 of the virtual image forming optical system 3.

Further, the image display element 10 is fixed to a frame body 16 having a rack on one side thereof, a gear 17 fitted to the rack, a diopter adjusting knob 18 interlocked therewith, and a virtual image forming optical system 3. It is held at a predetermined position by a guide surface 19 provided on the side surface for guiding and holding the diopter adjustment knob 18 by friction. In this configuration, when the diopter adjustment knob 18 is rotated in the direction of arrow A in FIG.
The rotation axis of 7 coincides with the fulcrum of the diopter adjustment knob 18, and the gear 17 rotates to move the frame 16 in which the gear fits, that is, the image display element 10 in the optical axis direction. Therefore, the relative distance between the image display element 10 and the lens 12 changes, and the diopter can be adjusted. Further, the image display element 10 is electrically connected by a cable 20 to a drive circuit 21 arranged above the apparatus main body 1.

In the above structure, when one of the knobs 5 at both ends of the apparatus body 1 is rotated, the shaft 4 idles with respect to the apparatus body 1 in conjunction with it, so that the virtual image screwed and fitted thereto. The forming optical system 3 is movable in the axial direction of the shaft 4, that is, in the eye width direction of the user 2. At this time, as shown in FIG. 3, the guide shaft 22 extending parallel to the shaft 4 is attached to the apparatus main body 1
By fixing a part of the virtual image forming optical system 3 thereto, the virtual image forming optical system 3 can be smoothly moved by being guided by the shaft 4 and the guide shaft 22. Therefore, the user 2 can select the virtual image visually recognizing eye 13 by his / her own judgment and easily switch to either the left or right eye, which is excellent in versatility and commonality.
Further, since this switching movement is performed in the direction of the eye width of the user 2, the optical axis 14 of the virtual image forming optical system 3 is adjusted to the user 2 by adjusting the movement amount according to the eye width of the user 2. Of the virtual image forming optical system 3 and the fatigue caused by the positional deviation between the optical axis 14 of the virtual image forming optical system 3 and the line of sight of the user 2 can be prevented.

Table 1 shows the results of subjective evaluation comparing the degree of fatigue when the virtual image is visually recognized by the effective eye and when the virtual image is visually recognized by the negative eye. For each effective and counter-effective eye,
A partially transmissive light-shielding plate 26 in front of the other eye for visually recognizing the virtual image
Was placed.

[0024]

[Table 1]

In the test, the virtual image forming optical system 3 shown in Example 1 was placed on the effective eye or the negative eye of eight subjects, and the task of inputting the task document was performed for one hour. Regarding the degree of fatigue, it was divided into four stages: A: no feel, B: feel a little, C: feel a lot, D: feel a lot, and the number of subjects was indicated by a circle, and tiredness remained after the work. The number of subjects is indicated by ●.

From Table 1, when visually recognized with a counter-effect eye,
It can be seen that the degree of fatigue after working is apparently lighter than when the virtual image is visually recognized with the working eye. Regarding the content of tiredness when a virtual image is visually recognized by the effective eye, there are many cases of complaining of fatigue of the effective eye, which is the virtual image visually observing eye rather than the counter-effective eye side. The present inventors presume about this result as follows.

The information on the effective eye side in human visual action is dominant in the entire visual information.
This is because the sensitivity is high in the optic nerve system including the cerebral nervous system on the effective eye side, and it is considered that the fatigue of the optic nerve system is caused by displaying the virtual image information with strong stimulation on the effective eye.

In this embodiment, the reaction eye determining means 23 is provided at the approximate center position 31 of the eye width of the user 2 for determining the reaction eye which is the virtual image visual eye. This counter-effect eye determination means 23
Is made up of a strip-shaped member as shown in FIG. 1 and is located closer to the user than the near point of the user 2, so it is naturally defocused for the user 2, but has a proper size. If so, its location and shape can be identified. Also,
The eye-reflective means 2 which is substantially at the center of the eye width of the user 2 and which is outside the virtual image forming optical system 3 in the virtual image viewing eye 13
By disposing 3, the counter-effect eye determination means 23 can be visually recognized by both eyes.

Here, the case where the right eye of the user 2 is the dominant eye will be described. A user 2 mounts the device body 1 on the head and arranges the virtual image forming optical system 3 in front of the left eye. At this time, as shown in FIG. 4, the virtual image 24 formed by the virtual image forming optical system 3 and the image by the counter-effect eye determining means 23 are relative positions when viewed with both eyes and the right eye which is the anti-virtual image visible eye 25. The amount of displacement of the relative position when closed is shown in FIG. When the virtual image forming optical system 3 is arranged in the right eye, which is the dominant eye, and the relative position when binocularly viewed is as shown in FIG. 4B, and when the left eye, which is the anti-virtual image visualizing eye 25, is closed. Similarly, FIG. 4B shows the relative position. When the respective shift amounts are compared, the left eye that was visually recognized when the relative position shift is large is determined to be the reaction eye, and the virtual image forming optical system 3 is moved to the reaction eye side to visually recognize the virtual image. In addition, when judging the counter-effect eye,
You can start with either the left or right eye. Further, the reaction-effect eye determining means 23 can be housed in the apparatus main body 1 after the reaction-effect eye determination, so that the reaction-effect eye determination means 23 does not get in the way during the work.

(Embodiment 2) FIGS. 5, 6, and 8 show the mounting state of the head-mounted display device according to the second embodiment of the present invention. FIG. 5 is a front view, and FIGS. It is a side view. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, the device body 1 is used by the user 2
On the outside of the virtual image forming optical system 3 as viewed from the above, a partially transmissive light shielding plate 26 having a size that partially covers the visual fields of both eyes of the user 2 is provided. The partially transmissive light-shielding plate 26 is a conventional means for preventing the contrast reduction of the virtual image information caused by the information incident on the anti-virtual image visually recognizing eye 25 in the monocular head-mounted display device. In the present embodiment, the partially transmissive light-shielding plate 26 is arranged outside the movement space in the movement of the virtual image forming optical system 3, and the virtual image forming optical system 3 is moved as described above so that either the left side or the right side of the user 2 is moved. Even if it is held in front of the eyes, the information of the anti-virtual image visually recognizing eye 25 can be partially omitted regardless of the movement.

On the partially transmissive light-shielding plate 26, the counter-effective eye determining means 2 is located at a substantially central position 31 of the eye width of the user.
7 is provided. As shown in FIG. 5, the counter-effect eye determination means 27 is a slit included in the partially transmissive light-shielding plate 26, and has a suitable size that allows the user 2 to identify it even when defocused, as in the first embodiment. .

The counter-effect eye determining means 27 provided on the partially transmissive light-shielding plate 26 becomes a blind spot due to the virtual image forming optical system 3 and cannot be viewed by both eyes when the apparatus main body 1 is mounted.

Therefore, the apparatus main body 1 is connected to the mounting means 7 via the hinge portion 6, and the virtual image forming optical system 3 is connected to the head portion via the hinge portion 6 to the point where the counter-effect eye determining means 27 can identify with both eyes. It can be moved in the direction of arrow B in FIG. 6, which is the upward direction. At this time, using the outside scene information 28 and the image obtained by the counter-effect eye determining means 27, the relative position when viewed with both eyes and the relative position when viewed with each of the left and right eyes will be described with reference to FIG. FIG. 7 shows an example in which the dominant eye of the user 2 is the right eye, and FIG. 7A shows the relative position when the binocular vision is switched to the monocular vision by the right eye. Similarly, b) shows a state when the binocular vision state is switched to the monocular vision by the left eye. The relative positions at this time are compared, and it is determined that the person who has viewed monocularly when the amount of deviation is large, that is, the left eye in the example of FIG.

Here, the counter-effect eye determining means 27 is disposed farther from the user 2 than the counter-effect eye determining means 23 in the first embodiment, and is visually recognized as much as it is closer to the near point of the user 2. Since it is easy, the above-described counter-effect eye determination can be performed more easily. In addition, the counter-effect eye determination means 2
7 is not limited to slits as long as the size and color can be identified by the user 2, and may be round holes, LEDs, printed matter, paint or the like.

Further, if the virtual image forming optical system 3 is moved in the upward direction of the head as described above, the counter-effect eye determining means 23 described in the first embodiment can be used as shown in FIG. , Similarly, it is possible to determine the counter-effect eye.

(Embodiment 3) FIG. 9 is a partially enlarged view of a head-mounted display device showing a third embodiment of the present invention, and shows a portion A in FIG.

In the second embodiment, when the slit, which is the reaction-effect eye determination means 27, is visually recognized by both eyes, the hinge portion is provided so that the reaction-effect eye determination means 27 does not become a blind spot of the virtual image forming optical system 3 for the virtual image visual recognition eye. The virtual image forming optical system 3 is moved in the upward direction of the head of the user 2 via the device 6. In the present embodiment, the counter-effect eye determination means 27 is made binocular in the same manner as a method different from the above method.

The virtual image forming optical system 3 is held on the apparatus main body 1 by a shaft 4 having a screw shape extending substantially in the width direction of the user 2 as in the first embodiment, and the shaft 4 has knobs 5 at both ends thereof.
By rotating the knob 5, it is movably held in the direction of the eye width of the user 2 as shown in FIG. 9 (a). At this time, the axis 4 has a length that allows the virtual image forming optical system 3 to be moved to be equal to or more than the pupil distance of the user 2. Since it is generally said that the maximum value of the human eye width is 72 mm, it suffices that the virtual image forming optical system 3 can move to the left and right beyond this eye width.
That is, at this time, as shown in FIG. 9B, if the reaction-effect eye determination means 27 is visually recognizable from the inner surface side of the virtual image forming optical system 3 by the virtual image visual observation eye 13, Therefore, the binocular vision of the counter-effect eye determination means 27 can be realized for all people.

As a result, as shown in FIG. 9B, the virtual image forming optical system 3 can be easily moved out of the line of sight of either the left or right to a position where the negative eye determining means 27 can be identified by both eyes. As described above, the counter-effect eye can be determined by comparing the relative positions when viewed with both eyes and when viewed with one of the left and right eyes. Note that the comparison of the relative positions of the virtual image 24 and the counter-effect eye determination means 27 is the same as in FIG. 7 of the second embodiment.

(Embodiment 4) FIGS. 10 and 11 show a mounted state of a head-mounted display device according to a fourth embodiment of the present invention, FIG. 10 being a front view and FIG. 11 being a side view. Also like the above-described embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

When determining the counter-effect eye as described above, either the left eye or the right eye must be closed. Therefore, some contraction action generated in the peripheral muscle of one open eye may affect the negative eye determination.

Therefore, between the apparatus body 1 and the user 2,
By providing the light-shielding means 29 that can be arbitrarily selected as the visible eyes of the user 2 from the binocular, one monocular, and the other monocular,
It is possible to judge the counter-effect eye without crushing the eye. The light-shielding means 29 is in the shape of glasses, and the light-shielding portion is composed of a liquid crystal display element, a polarizing element or the like. As for the method of controlling the transmittance of the light-shielding portion, when a liquid crystal display element is used, light-shielding selection switches 30 are provided on both side surfaces of the light-shielding means 29, and light-shielding and transmission are alternately repeated each time it is pressed. Both sides of the light-shielding selection switch 30 are independent of each other, and only the side on which the light-shielding selection switch 30 is pressed repeats light-shielding and transmission alternately. For example, FIG. 12 shows a state in which the right eye side is shielded from light and the left eye side is transmitted. By repeating this operation, both binocular vision and monocular vision are possible. When a polarizing element is used in the light shielding portion, a slide type switch is provided on the lower surface of the light shielding means 29 to mechanically shield the left and right visual fields in front of the eyes arbitrarily. The light blocking means 29 may be integrated with the apparatus body 1.

(Embodiment 5) FIGS. 13 to 16 are flowcharts relating to a method of mounting a head-mounted display device in a fifth embodiment of the present invention. FIG. 13 shows the work after mounting the device body. Until the start, FIG. 14 shows Example 1
FIG. 15 shows the reaction-effective eye determination method in Examples 2 and 3, and FIG. 15 shows the reaction-effective eye determination method in Examples 2 and 3.
9 is a flowchart showing a counter-effect eye determination method according to the fourth embodiment. Similar to the above-described embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

As described above, it has been found that the fatigue can be reduced by visually recognizing the virtual image with the reaction eye. Therefore, the present invention has a structure for determining the reaction eye in the apparatus main body. Therefore, by clarifying the procedure from the mounting of the main body of the apparatus to the work, it is possible to prevent erroneous selection of the virtual image viewing eye and fatigue caused by the incorrect mounting.

As shown in FIG. 13, the apparatus main body 1 is held on the head by the mounting means 7 so that the counter-effect eye judging means 23 or 27 is located at the approximate center position of the eye width of the user 2.
Next, the reaction eye of each user 2 is determined by the reaction eye determination method described in Examples 1 to 4. After that, the knob 5 is turned to switch the virtual image forming optical system 3 to the front of the reflex eye, but at that time, the interpupillary adjustment is performed in parallel. Further, the diopter adjustment knob 18 is used to adjust the diopter while watching the virtual image 15, the brightness of the backlight is adjusted to the optimum brightness, and the mounting is completed.

The procedure for determining the counter-effect eye described in the first embodiment is shown in FIG. 14. After the counter-effect eye determining means 23 is adjusted to the approximate center position of the visual fields of both eyes, the virtual image forming optical system 3 is set. It is placed in front of either the left or right eye, and as shown in FIG. 4, the image by the counter-effect eye determination means 23 and the virtual image 24 formed by the virtual image forming optical system 3 are viewed with both eyes, and the relative position (A) is determined. to see. Next, the relative position (B) with the anti-virtual image visual eye 25 closed is viewed. Further, (A) and (B) are compared to remember the shift amount (C). Next, the virtual image forming optical system 3 is moved to the opposite eye, the shift amount (F) is observed in the same procedure, and (C) and (F) above are compared, and when the shift amount of the relative position is large, The eye that was monocular is judged to be the counter-effect eye.

Similarly, the procedure of Embodiments 2 and 3 is shown in FIG. When trying to visually recognize the counter-effect eye determination means 27 for the virtual-image visually recognizing eye, it becomes a blind spot of the virtual-image forming optical system 3. Therefore, as described above, the virtual-image forming optical system 3 reaches a position where the counter-effect eye determination means 27 can see both eyes. Is moved in the upper direction of the head via the hinge portion 6, or the knob 5 is turned to move in the eye width direction of the user 2. Then, the reaction eye is determined by the method as described above.

FIG. 16 shows the procedure described in the fourth embodiment. As in FIG. 15, the virtual image forming optical system 3 is moved, the shading means 29 is attached between the apparatus body 1 and the user 2, and the shading selection switches on the sides of both eyes are arbitrarily selected. As described above, a monocular eye is selected and a counter-effect eye is determined. After that, the light shielding means is housed and the virtual image forming optical system 3
To the counter-effect eye.

According to the above procedure, it is possible to smoothly and easily determine the counter-effect eye, which is the virtual image visual recognition eye, using any of the configurations of the first to fourth embodiments. It prevents selection and eliminates fatigue caused by it. Further, it is possible to prevent fatigue caused by incorrect mounting or proper mounting.

[0051]

As described above, the head-mounted display device of the present invention is provided with the switching means for switching and holding the virtual image forming optical system in front of either one of the left and right eyes of the user. The user can easily select the eye that visually recognizes the virtual image, and is excellent in versatility and commonality. Further, according to the experiment by the applicant, it has been found that the fatigue is reduced when the virtual image is visually recognized by the counter-effect eye compared to when the virtual image is visually recognized by the counter-effect eye.

Further, the counter-effect eye determination means is provided on the main body of the apparatus or on the partially transmissive light-shielding plate of a size that partially covers the visual fields of both eyes provided outside the virtual image forming optical system when viewed from the user. By comparing the relative position of the image between the virtual image or the outside scene information and the reaction-effect eye determination means with the binocular, one monocular, and the other monocular, the reaction-effect eye, which is a virtual image visible eye, is attached to the apparatus main body. Since it is possible to easily make determinations as they are and avoid erroneous selection of the virtual image visually recognizing eye, it also leads to a reduction in fatigue.

In addition, since the main body of the apparatus is held by the mounting means via the hinge portion which is rotatable in the upper direction of the user's head, the reaction-effect eye determining means becomes a blind spot for the virtual image visual eye when determining the reaction-effect eye. Since it can be moved to a position where it can be visually recognized, it is possible to easily perform the counter-effect eye determination with the apparatus body attached.

Furthermore, by setting the amount of movement of the virtual image forming optical system in the direction of the pupil width to be equal to or larger than the pupil distance of the user, it is possible to easily perform the counter-effect eye determination means with the apparatus main body being mounted, similar to the above effect. You can see with both eyes.

Here, when performing the above-mentioned counter-effect eye determination, by using eyeglasses equipped with a light-shielding means together, it is possible to determine whether the left or right eye is crushed in the counter-effect eye determination. The effect can be eliminated.

Further, according to the method for mounting the head-mounted display device of the present invention, since the reaction eye judgment can be performed smoothly and easily with the main body of the device mounted, the workability and the operability are excellent, and the virtual image visual error is erroneous. Fatigue due to selection can be prevented. Furthermore, it is possible to prevent fatigue caused by incorrect mounting or proper mounting.
