Description

The present invention relates to a sun-shielded wearable computer used outdoors.

In particular, when controlling an unmanned aerial vehicle (hereinafter referred to as a drone) outdoors in fine weather, it can be used as a wearable computer with a shield in the shape of glasses that allows the front to be seen while displaying the camera image transmitted from the drone. Regarding the shield used.

In recent years, with the advent of drones equipped with cameras, even if humans do not climb dangerous places or high places, they can remotely control the drone, shoot it with the camera equipped with the drone, and record the shot image with Bluetooth (registration). It has become possible to display on a personal computer or a tablet terminal by using a communication means such as short-range communication (trademark). By being able to display and check the images taken by the drone camera controlled from such a remote place with the display means at hand, it is possible to quickly check the situation in a disaster area where traffic is blocked. And, the usage is expanding, such as being able to check the status of agricultural products planted in a wide area.

(Wearable computer)
More specifically, as shown in FIGS. 1 and 2 of Patent Document 1, the configuration and hardware configuration of the wearable computer are as follows. The wearable computer described below has already been put on the market as described in Non-Patent Document 1. Its range of use is expanding.

The wearable computer mainly includes a control device and a display device. The display device is a spectacle-type device, and is arranged and used in front of the user's eyes with the user's nose and ears as fulcrums. The display device is entirely made of a transparent material such as a transparent resin, and has a light guide portion located in front of the left eye and a light guide portion located in front of the right eye when the user wears the display device. It is equipped. The light guide portion is made of a resin that transmits visible light, and includes a display portion made of a half mirror, which will be described later. Then, the user can visually recognize the scenery in the visual field by the visible light input through the light guide unit and the display unit from the visual field spreading outside the display device when viewed from the user. However, the scenery in the field of view that can be visually recognized from the display unit in the display device is less clear than the scenery that is visually recognized through the light guide unit.

One of the reasons is that the display unit is a half mirror arranged so as to be inclined with respect to the line-of-sight direction when the user's left eye and right eye look at the front. Since it is a half mirror, there is no transparency of nearly 100%, so that the sharpness is lower than that of other parts of the display device.

As shown by the broken line arrow in FIG. 2 of Patent Document 1, visible light from the visual field passes through the display unit and reaches the left eye and the right eye. Further, as indicated by the arrow of the alternate long and short dash line, the visible light output by the left-eye image projection unit and the right-eye image projection unit is reflected by the display unit and reaches the left eye and the right eye. Therefore, the display unit is a screen capable of transmitting light input from the user's field of view and displaying an image. With the display unit, the user can see visible light from the outside (field of view) of the display device, a left-eye image projection unit (display unit composed of the half mirror), and a right-eye image projection unit (composed of the half mirror). At the same time, the image formed by superimposing the visible light output by the display unit) and the image of the landscape formed by the visible light from the light guide unit in the portion where the display device is not arranged in the field of view are visually recognized. can do.

The control device includes a control unit including a CPU, RAM, ROM, etc., a recording medium, an interface, a button as an input means, and a display, and the control unit executes a program recorded in the ROM, the recording medium, or the like. be able to.

The button is provided so as to be pushable on the surface of the control device of the rectangular parallelepiped, and the control unit can detect that the push operation for the button has been performed. By pushing the button, the user can perform various instructions and selections such as an instruction to start execution of a predetermined function and an instruction to suspend the predetermined function.

A display is a device including a display for displaying an arbitrary image and a sensor for detecting a touch at an arbitrary plurality of positions on the display. The control unit can display an arbitrary image on the display by outputting a control signal to the display. Further, the control unit can acquire an instruction or the like by touching the display by the user based on the output signal from the display. Wiring extending from the display device is connected to the interface.

Then, the control unit can execute various programs recorded in a ROM, a recording medium, or the like. In the present embodiment, these programs include various application programs such as an operating system program and a moving image playback program, and a command assignment program that assigns sensor outputs to commands. The control unit can execute various functions by processing these operating system programs and application programs. For example, the operating system program allows the control unit to perform operations on the above-mentioned buttons and accept operations by each button. In the present embodiment, when the control unit executes the operating system program, the user operates a button to perform sleep, wakeup from the sleep state, or the like to stop a part of the functions in the control device and the display device. be able to.

Further, the control unit can execute various functions by the application program. For example, using the image taken by the drone camera, the control unit as an image reproduction means generates an image for the left eye and an image for the right eye for each frame, and the generated images are sequentially transmitted through the interface. Output to the left-eye image projection unit and right-eye image projection unit. As a result, an image for each frame is displayed via the display unit of the display device. The user can visually recognize the moving image played together with the object in the field of view.

Since the legal regulation of drone operation requires that the user (drone operator) has sufficient visibility, the above-mentioned wearable computer meets the legal regulation requirement. It will be.

(Drone)
The drone developed in recent years is equipped with an attitude control means for hovering at rest in a non-operated state, so that the drone operator who is the user of the wearable computer has abandoned the operation. However, there is no fear that the drone will crash. Rather, it remains stationary, reducing the risk of the user losing sight of the drone.

An environment in which the user cannot determine the visibility (for example, touching a drone or crop during operation) even though the visibility of the screen (half mirror) displayed in the transmissive part is reduced due to the influence of external light such as sunlight. If you are working while checking the image on the screen while visually recognizing through the light guide of the wearable computer), interrupt the operation or work, or move the position and resume the operation or work. I had to do it.

In the case of outdoor farm work, it is also possible to prevent the ingress of outside light with a straw hat with a large brim in the shade. However, in the case of operating the drone, the brim of the hat narrows the field of view and the drone cannot be seen directly through the light guide, which causes a problem of losing the position of the drone with the naked eye.

The present invention includes a receiving unit that receives video information transmitted through the wireless communication interface of the drone, and is arranged at a position where a transparent portion for the left and right eyes can be secured while the user is wearing the transparent portion. A wearable computer with a shield in which a half mirror serving as a display unit for displaying the image information is arranged at a position where the left and right eyes of the transparent portion face each other, and the transparent portion is a light shield that shields external light. A shield is provided, and the light-shielding shield has a first position on the back side of the display unit to prevent external light from entering the half mirror, and the light-shielding shield is transmitted from the half mirror to visually recognize the outside. An operation unit that can be operated is provided at a second position that does not interfere with the light shielding shield, and the size of the light shielding shield is set to a size that covers the outer shell of the display surface of the half mirror. An insertion receiving portion having a U-shaped cross section is provided, and the insertion receiving portion is fitted into the thick portion of the transparent portion so as to be detachable and movable to the first position and the second position. It is characterized by being made .

When visually confirming the drone through the transparent part and visually recognizing the image transmitted from the drone through the half mirror, depending on the position of the drone, sunlight may be seen through the transparent part or the half mirror. It may enter, but such a problem can be solved. That is, when sunlight is incident from the transparent portion of the wearable computer and incident on the back side of the display unit which is a half mirror, there arises a problem that the image displayed on the display surface of the display unit is blurred or it becomes difficult to visually recognize the image. Cheap. Such a problem can be reduced by appropriately moving the light shielding shield to the first position. Such a problem arises from the positional relationship between the sun and the display when chasing the drone visually. If you lose sight of the drone visually, it may collide with obstacles such as electric wires, so it is necessary to visually confirm the actual position of the drone for operation. According to the present invention, even under such a situation, the image received from the drone can be visually recognized more clearly.

Further, since the size of the light-shielding shield is set to cover the outer surface of the display surface of the image received from the drone, the entire display image can be clearly seen. Therefore, it becomes easy to grasp the boundary between the image obtained by direct visual inspection and the displayed image.

Further, as the second invention, there is a case where work guidance is given to agricultural products, and a display unit displays an image for remote guidance while the user himself / herself visually recognizes the hands of the wearable computer user outdoors . It is a wearable computer with a shield that can be displayed on the screen and visually recognized at the same time to continue the work.
It is equipped with a receiving unit that receives images for giving work guidance on agricultural products from the outside, and the transparent parts for the left and right eyes are arranged at a position where the user can secure the field of view while wearing the transparent parts. A half mirror that serves as a display unit for displaying the image for instruction is arranged at a position where the left and right eyes of the above face each other.
The transparent portion is provided with a light-shielding shield that shields external light.
The light-shielding shield has a first position on the back surface side of the display unit to prevent external light from entering the half mirror, and a second position that does not interfere with the outside viewing through the half mirror. Equipped with an operable operation unit at the position
Moreover, the size of the light-shielding shield is set to a size that covers the outer shell of the display surface of the half mirror.
An elastic U-shaped cross-section insertion receiving portion is provided at one end of the light-shielding shield, and the insertion receiving portion is fitted into the thick portion of the transparent portion so as to be removable and detachable from the first position. It is characterized in that it is configured to be movable to the second position .

For example, a worker who actually performs farm work wears a wearable computer. In this case, the worker can visually recognize the actual work object such as the fruit to be picked and the branches and leaves to be selected through the transparent part for the left and right eyes, and also visually recognize the image displayed on the display unit. can. The displayed image is, for example, an image instructing the contents of farm work. One example of the situation is real-time remote farm work guidance. For example, an image of an agricultural product is taken via a wearable computer worn by a worker, and this image is received and displayed by a device at a remote location. When an instructor at a remote location gives a mark or the like to the displayed image, the marked image is transmitted to the wearable computer of the worker.
When visually confirming the crop through the transparent part and visually recognizing the image of the instruction transmitted from a remote place through the half mirror, sunlight is transparent depending on the position of the visually recognizable crop. It may be seen through a half mirror or a half mirror, but such a problem can be solved. That is, when sunlight is incident from the transparent portion of the wearable computer and incident on the back side of the display unit of the half mirror, the image displayed on the display surface of the display unit is blurred and difficult to see. It can be reduced by appropriately moving the light-shielding shield. Such a problem arises from the positional relationship between the sun and the display unit when visually observing the objects of agricultural work in sequence. During work, it is necessary to directly visually confirm the position of the crop, but even under such circumstances, it is possible to visually confirm the instructional image received from the remote device more clearly. Become.

In addition, the third invention is characterized in that the light shielding shield is made of a material that transmits a part of light.

The light-shielding shield is made of a material that transmits part of the light, so if the user turns his or her head after following an object such as a drone or an agricultural work object, the sunlight will be directly in the field of view. However, it is possible to grasp both the position of the object and the image of the display unit while suppressing glare.

In addition, the fourth invention is characterized in that the light-shielding shield has a visible light transmittance lower than the visible light transmittance when the transparent portion and the half mirror are combined.

As a result, when the light-shielding shield is operated and the light-shielding shield is positioned at a second position that does not interfere with the external visibility through the half mirror, the glare due to sunlight entering the field of view passing through the second position. Can be suppressed. Therefore, the visibility of the information displayed on the display unit is improved.

An elastic insertion receiving portion having a U-shaped cross section is provided at one end of the light-shielding shield, and the insertion receiving portion is fitted into the thick portion of the transparent portion to be detachable, and the first position and the second position. Since it is configured to be movable, the light-shielding shield can be moved to a position where the half mirror is exposed to sunlight when necessary, and the display image on the display unit can be easily viewed.

Then, it is preferable that the light-shielding shield is provided with an operation unit for gripping the light-shielding shield by hand and operating and moving the light-shielding shield. In this case, since the drone's operating device is released or not operated, it is preferable that the drone is provided with an attitude control device that maintains the hovering state when the drone is not operated.

According to the present invention, when visually confirming a real object such as a drone or an agricultural product through the transparent portion and visually recognizing an image transmitted from a remote place such as a drone through the half mirror, it is visually recognized. Depending on the position of the actual object, sunlight may enter the eyes through the transparent part or the half mirror, and such a problem can be solved. That is, when sunlight is incident from the transparent portion of the wearable computer and incident on the back side of the display unit which is a half mirror, the light-shielding shield is used to prevent the image displayed on the display surface of the display unit from being blurred or difficult to see. It can be reduced by appropriately moving it to the first position. Such problems occur due to the relationship between the position of the drone, the sun, and the display when chasing the drone visually. If the position of the drone is lost visually, there is a risk of collision with an obstacle such as an electric wire, so it is necessary to directly visually confirm the position of the drone. According to the present invention, even under such a situation, the image received from the drone can be visually recognized more clearly.

In addition, as in the case where you cannot take your eyes off the drone, when work guidance is given from a remote location on work on agricultural products such as mandarin orange trees, the user himself / herself takes care of the wearable computer user. The present invention is useful when it is necessary to display an image for receiving guidance on the display unit and simultaneously visually recognize the image while visually recognizing it to continue the work. According to the present invention, for example, even in a situation where the degree of freedom of movement is restricted so as not to allow sunlight to enter, the received instructional video can be clearly visually recognized and visually recognized by being combined with an image of an actual agricultural product at hand. Is also possible.

A mode, (C) is a mode in which both of the light-shielding shields are arranged at a second position outside the corresponding half mirror, and (D) is a form in which one of the light-shielding shields is arranged at a second position outside the other. The mode in which the light-shielding shield of No. 1 is arranged at the first position is shown. It is a figure which shows the modification of the light-shielding shield of the wearable computer with a shield. It is a schematic diagram which shows the modification of the light-shielding shield device shown in FIG. (A) shows a form in which the light-shielding shield moves in the same direction when the grip portion is slid, and (B) shows a form in which the light-shielding shield moves in different directions so as to approach each other. (C) shows a form in which the light-shielding shields move in different directions so as to separate from each other. It is a usage state explanatory diagram which shows the basic structure of the whole wearable computer.

An embodiment of the present invention will be described below. Here, regarding the structure of a wearable computer and a drone system (a system consisting of a drone operation unit and a drone operated in pairs with the drone operation unit) equipped with a stationary state holding means for holding the drone in a stationary state when there is no operation. Is based on the technical content described in the background technology and a known device, and therefore, a detailed description thereof will be omitted here. It is displayed through the half mirrors 5 and 5 (display unit) for the left and right eyes in a state where the posture is not desired to be changed because it is necessary to maintain the visual state with the naked eye, which is a subject of the present invention. One of the situations in which the visibility of the camera image from the outside is ensured is a configuration in which the camera image displays the image information transmitted from the drone on the display unit. The other is when the worker is instructed to work on agricultural products such as mandarin oranges from a remote location, and the user himself / herself visually recognizes the hand of the wearable computer user who is the worker at the remote location. There is a situation in which it is necessary to display an image for guidance from the user on the display unit and simultaneously visually recognize the image to continue the work. In this case as well, depending on the work, there are situations in which the degree of freedom for the user to move so that outside light does not enter is restricted.

FIG. 1 is a perspective view showing an outline of a wearable computer 1 with a shield. The shielded wearable computer 1 includes a receiving unit J (see FIG. 6) that receives video information transmitted through a wireless communication interface of a drone (not shown in FIG. 1). The shielded wearable computer 1 includes a control device C (see FIG. 6) and a display device D'. The receiving unit J is provided in the control device C. FIG. 1 schematically shows the structure of the display device D'in the shielded wearable computer 1. The control device C will be described later. The shielded wearable computer of the present invention is not limited to the form shown in the figure, and for example, a receiving unit may be provided in the display device. Further, the entire control device may be provided integrally with the display device.

The display device D'of the wearable computer 1 with a shield consists of a resin-made spectacle lens portion 2 and 2 in which a pair of left and right transparent portions are arranged side by side, and a pair of ear-hook frames extending from both sides of the spectacle lens portions 2 and 2. It has 3, 3 and a hinge portion 4 provided at a connection portion between the ear hook frame 3, 3 and the spectacle lens portions 2, 2. The ear hook frames 3 and 3 are rotatably supported and mounted on the spectacle lens portions 2 and 2 by the hinge portions 4.

The display device D'of the wearable computer 1 with a shield is in a state of being hung on the ears of the drone operator by the ear hook frame 3 (wearing state), and the user secures a view through the pair of transparent portions for the left and right eyes. It is placed in a position where it can be. Further, at positions where the left and right eyes of the transparent portion face each other, half mirrors 5 and 5 formed on the surface on the side where both eyes are located when the display device D'that displays the image information is mounted are arranged (sealed). Has been). The user can visually recognize the outside scenery that can be seen through the spectacle lens portions 2 and 2 which are transparent portions and the image information received from the drone displayed on the half mirrors 5 and 5 in a layered state. The half mirrors 5 and 5 are shown in FIG. 1 so as to be sealed in parallel with the spectacle lens portions 2 and 2, but in reality, the images guided from the hinge portion 4 side are captured by the left and right eyes. The angle is set to 45 degrees upward in order to reflect in the direction. More specifically, an image projection unit (not shown) is provided near the hinge unit 4. Light based on the video information transmitted from the receiving unit J (see FIG. 6) is output from the video projection unit toward the half mirror 5, and the light reflected by the half mirror 5 is recognized by the operator as an image.

In front of the spectacle lens portions 2 and 2, light-shielding shields 10 and 10 made of a resin film that shields external light are provided. The light-shielding shields 10 and 10 are provided so as to be able to be arranged on the back side of the half mirrors 5 and 5, which are display units for displaying video information. The front, back, left, and right in the present specification are the front, back, left, and right as seen from the person wearing the display device D'of the wearable computer 1 with a shield. Further, the back surface of the display unit is a front surface in front of and behind the person wearing the display device D'. That is, the back side of the display unit is the side opposite to the wearer.
The light-shielding shields 10 and 10 are provided with grip portions 10A and 10A for the user to operate in the left-right direction. The display units 5 and 5 (half mirrors 5 and 5) can be operated by the user to the first position and the second position by sliding the grip portions 10A and 10A to the left and right. The first position is the position on the back side of the display units 5, 5 (half mirrors 5, 5). The light-shielding shields 10 and 10 at the first position prevent external light from incident on the half mirrors 5 and 5. The second position is a position where the light-shielding shields 10 and 10 penetrate through the half mirrors 5 and 5 and do not interfere with the visual recognition of the outside. As will be described later, the light-shielding shields 10 and 10 do not completely prevent light, but prevent a part of light from passing through. However, the light-shielding shields 10 and 10 can also be formed of a material that completely blocks light.

In FIG. 1, the light-shielding shield 10 corresponding to the left eye is arranged at a second position that does not interfere with the appearance of the outside through the half mirror 5. Further, the light-shielding shield 10 corresponding to the right eye is arranged between the first position and the second position. The light-shielding shield 10 corresponding to the right eye is in a state of being moved from the first position to the second position. The positions of the two light-shielding shields 10 in the example of the present embodiment can be set independently on the left and right sides.
The light-shielding shields 10 and 10 of the present embodiment are made of a material that transmits a part of light. The light-shielding shields 10 and 10 are made of, for example, a translucent gray resin material. Therefore, the light-shielding shields 10 and 10 do not completely prevent the external light from being incident on the half mirrors 5 and 5 even when they are in the first position, but a part of the external light is on the half mirrors 5 and 5. Incident. Therefore, for example, even when the operator follows the drone in flight and the sun enters the field of view of the half mirrors 5 and 5, the image through the half mirrors 5 and 5 is visually recognized and the position of the sun is set. It becomes visible. Further, even when the sun and the drone enter the field of view of the half mirrors 5 and 5, the image through the half mirrors 5 and 5 can be visually recognized, and the position of the sun and the position of the shadow of the drone can be visually recognized.
That is, the visible light transmittance of the light-shielding shield 10 can be visually recognized through the light-shielding shield 10, the spectacle lens unit 2, and the half mirror 5 even when the sun enters the field of view, and is displayed through the half mirror 5. The image is visible. Further, the light-shielding shield 10 of the present embodiment has a visible light transmittance lower than the visible light transmittance when the spectacle lens portion 2 and the half mirror 5 are combined. When the light-shielding shield 10 is in the second position away from the half mirror 5, the light-shielding shield 10 can suppress glare due to sunlight entering the field of view passing through the second position. For example, when the sun is seen at a position deviated from the half mirrors 5 and 5, the glare is suppressed and the displayed image can be visually recognized through the half mirrors 5. For example, the light-shielding shield 10 has a transmittance corresponding to category 1 or higher in the category corresponding to the visible transmittance of the lens defined in ISO / DIS8980-3. The light-shielding shield 10 preferably has a transmittance corresponding to category 4 from the viewpoint of high visibility when the sun enters the field of view.

FIG. 2A is a perspective view showing a detailed shape of the light-shielding shield 10, and FIG. 2B is a side view. FIG. 2C is an explanatory diagram of the shielded wearable computer 1 with respect to the detailed shape of FIG. 2A.
Further, the light-shielding shield 10 will be described in detail. One end of the light-shielding shield 10 is provided with an elastic insertion receiving portion 11 having a U-shaped cross section. The insertion receiving portion 11 receives the spectacle lens portions 2 and 2, which are transparent portions shown in FIG. The spectacle lens portion 2 is fitted into the insertion receiving portion 11 so that the insertion receiving portion 11 is hooked on the thick portion X of the spectacle lens portion 2 shown in FIG. The display device D'in FIG. 1 is configured such that the light-shielding shield 10 is detachably attached to and detached from the spectacle lens portion 2 and is movable to the first position and the second position.
As shown in FIG. 2C, the display device D of the shielded wearable computer 1 may include a cover 22 for preventing the light-shielding shields 10 and 10 from falling off. The cover 22 is a plate-shaped member made of a material that transmits light. The cover 22 is arranged so as to sandwich the light-shielding shields 10 and 10 between the cover 22 and the spectacle lens portion 2. The cover 22 is fixed to the spectacle lens portion 2, but a gap is provided between the cover 22 and the spectacle lens portion 2 for the light-shielding shields 10 and 10 to move.
As shown in FIG. 1, the size of the light-shielding shields 10 and 10 is set to a size that covers the outer shell of the display surface of the half mirrors 5 and 5. That is, the width dimension H of the light-shielding shield 10 is larger than the width h of the half mirror, and the height of the light-shielding shield 10 is larger than the width r of the half mirror. The height of the half mirror 5 is larger than the width R of the spectacle lens portion 2.

The drone operator usually places the shading shields 10 and 10 in the first position when flying the drone near a straight line connecting the operator and the sun. As a result, the operator can visually recognize the image displayed through the half mirror 5 while suppressing the glare of sunlight. The operator can also see the position of the shadow of the drone flying near the sun in the field of view. Therefore, it is possible to continue maneuvering while visually recognizing the displayed image without taking the eyes off the drone flying near the sun.

On the other hand, when flying the drone at a position away from the straight line connecting the driver and the sun, the drone operator usually arranges two light-shielding shields 10 and 10 in the second position. For each of the light-shielding shields 10 and 10, the second position is provided on both the left and right sides of the first position. If the drone is in the center of the field of view and the sun is in the field of view, the positions of the shading shields 10 and 10 will be moved to the left or right side of the center with the sun. For example, when the sun is visible to the right, the shading shields 10 and 10 are usually moved to a second position to the right of the first position. Also, when the sun is visible to the left, the shading shields 10 and 10 are usually moved to a second position to the left of the first position. As a result, the image displayed through the half mirror 5 can be visually recognized while suppressing the glare of sunlight. Further, when the light-shielding shields 10 and 10 suppress the sunlight in the second position, the drone is visually recognized at the position where the light-shielding shields 10 and 10 are not present. You can continue.

However, it is not necessary for both of the two light-shielding shields 10 and 10 to move to the left or right. The positions of the two light-shielding shields 10 and 10 can be set according to the flight mode of the drone, the position of the sun, and the like. For example, the position of each of the two shading shields 10 and 10 can be set according to the presence of a sun-reflecting object, such as a high-rise building or the sea / lake.

(A), (B), (C), and (D) of FIG. 3 show four types in which the light-shielding shields 10 and 10 are moved. (A) is a form in which both the light-shielding shields 10 and 10 are arranged closer to the center in the left-right direction than the corresponding half mirrors 5 and 5, that is, at the second position inside, and (B) is the light-shielding shields 10 and 10. A form in which both are arranged in the first position, (C) is a form in which both of the light shielding shields 10 and 10 are arranged in a second position outside the corresponding half mirrors 5 and 5, (D) is a form in which both are arranged in the first position. A mode is shown in which one of the light-shielding shields 10 is arranged at the outer second position and the other light-shielding shield 10 is arranged at the first position.
The first position and the second position are from the positions shown in FIG. 3 due to the individual difference of the operator who is the wearer, the adjustment positions of the half mirrors 5 and 5, and the angle at which the incident light can be shielded. It may shift.

FIG. 4 is a diagram showing a modified example of the light-shielding shields 10 and 10 of the wearable computer with a shield. The light-shielding shields 10 and 10 are fixed to the moving belt A1, and the moving belt A1 is stretched on a pair of bearing shaft pins A2. The bearing shaft pin A2 and the moving belt A1 constitute a light-shielding shield device A. The bearing shaft pin A2 is provided, for example, in the vicinity of the hinge portion 4 (see FIG. 1) that connects the ear hook frame 3 and the spectacle lens portion 2. The light-shielding shields 10 and 10 fixed to the moving belt A1 slide one of the grip portions 10A and 10A to the left and right, so that the other grip portion 10A is not operated at once in the first position and the second position. It is possible to move between. For example, the bearing shaft pin A2 may be configured as an extension of the rotation shaft of the hinge portion 4 connecting the ear hook frame 3 and the spectacle lens portion 2. By integrating the bearing shaft pin A2 with the rotation shaft of the hinge portion 4, the light-shielding shield device A can be integrally configured with the display device D'of the shielded wearable computer 1.

FIG. 5 is a schematic view showing a modified example of the light-shielding shield device A shown in FIG. FIG. 5 shows the structure of the light-shielding shield device as viewed from above.

It is provided with a portion D2. The light guide portions D2 and D2 correspond to the spectacle lens portions (transparent portions) 2 and 2 shown in FIG. In the wearable computer 1 shown in FIG. 6, the left and right light guide portions D2 are integrally provided. The light guide portion D2 is made of a resin that transmits visible light. The light guide portion D2 may be transparent, or may be made of a material that blocks a part of light. The light guide unit D2 is provided with a display unit D1 composed of a half mirror. The display unit D1 corresponds to the half mirror 5 shown in FIG. The user can visually recognize the scenery in the field of view by the visible light input through the light guide unit D2 and the display unit D1. However, the scenery in the field of view that can be visually recognized from the display unit D1 in the display device D is less clear than the scenery that is directly transmitted through only the light guide unit D2.
One of the reasons is that the display unit D1 is a half mirror arranged so as to be inclined with respect to the line-of-sight direction when the user's left eye and right eye look at the front. Since the half mirror does not have nearly 100% transparency, the sharpness is lower than that of the other parts of the display device D.
Visible light from the external visual field of the wearable computer 1 passes through the display units D1 and D1 and reaches the left eye and the right eye. Further, visible light output from each of the left-eye image projection unit and the right-eye image projection unit is reflected on the surfaces of the display units D1 and D1 facing the eyes and reaches the left eye and the right eye. Therefore, the display unit D1 functions like a screen capable of transmitting light input from the user's field of view and displaying an image. The display unit D1 allows the user to visually recognize an image formed by superimposing visible light from the outside (field of view) of the display device and visible light output by the left-eye image projection unit and the right-eye image projection unit. can do. Furthermore, the user can simultaneously visually recognize the image of the landscape seen from the light guide unit D2 that does not overlap with the display unit D1 in the field of view.

Can run the program. The interface communicates with internal and external devices. The button E is provided on the surface of the rectangular parallelepiped control device so as to be pushable, and the control unit can detect that the push operation for the button E has been performed. By pressing the button E, the user can perform various instructions and selection operations such as an instruction to start execution of a predetermined function and an instruction to suspend the predetermined function. For example, the user operates the button E to display an image via the display unit D1.
The control device C includes a receiving unit J for receiving video information. The receiving unit J receives video information transmitted through a wireless communication interface of a drone or a remote device (not shown). The receiving unit J transmits the received video information to the display device D. The display device D displays an image based on the image information received by the receiving unit J.
The display F displays an arbitrary image. The display F is a device including a sensor that detects a touch at an arbitrary plurality of positions on the display F. The control unit can display an arbitrary image on the display F by outputting a control signal to the display F. Further, the control unit can acquire an instruction or the like by touching the display F by the user based on the output signal from the display F. Wiring G extending from the display device is connected to the interface.
Then, the control unit can execute various programs recorded in a ROM, a recording medium, or the like. In the present embodiment, these programs include various application programs such as an operating system program and a moving image playback program, and a command assignment program that assigns sensor outputs to commands. The control unit can execute various functions by processing these operating system programs and application programs. For example, the operating system program allows the control unit to perform operations on the above-mentioned buttons and accept operations by each button.

Further, the control unit can execute various functions by the application program. For example, the control unit as a means for reproducing the image taken by the drone camera generates an image for the left eye and an image for the right eye for each frame, and the generated images are sequentially transmitted to the left eye image via the interface. Output to the projection unit and right eye image projection unit. As a result, the image for each frame is displayed on the display unit D1 of the display device D, and the user can visually recognize the moving image reproduced together with the object in the visual field.
In the field of eyeglasses such as sunglasses, there is a lens in which a colored lens that shields ultraviolet rays and sunlight is freely flipped up in front of a transparent lens. Since the film is not used as a light-shielding shield, there is a problem that the weight cannot be reduced, and the outer shape of the half mirror is large as in the present invention, and other transparent parts can be made so as not to impair the translucency. Not. In the case of the present invention, it is significant to secure a region that can be directly viewed other than the projection plane of the half mirror.
