Description

  The present invention relates to a head mounted display device of a type in which an image output from an image output unit is directly viewed with both eyes through an eyepiece.

  The principle of the optical motion capture system was proposed by Rashid et al. In 1980. This system attaches a marker to each part of the body, shoots the position with multiple cameras, estimates the 3D position by the principle of stereo (trigonometry), the current optical motion capture system, Basically the same method is used.

  The main commercial motion capture systems currently on the market use multiple infrared cameras and infrared projectors, and people (actors) attach markers made of reflective material to their bodies. On the infrared camera, an image of the marker reflecting the light of the infrared projector is projected. The projected images of the markers obtained by each camera are associated between the cameras, and the three-dimensional position of each marker is obtained by the stereo method. By mapping (inverse kinematics) from the obtained marker group to a pre-defined multi-joint model of the human body, the position, joint angle, etc. of the person can be obtained.

  The advantages of this method are that, firstly, the marker itself is small and light, and there is no connection object such as a wire, so the movement of the actor is relatively free. Second, it is high by changing the shutter speed of the camera. It is possible to perform measurement at a frequency, and thirdly, the position detection accuracy is high.

  Using such a commercial motion capture system, the usage as shown in Patent Document 1 is a general usage as a commercial head mounted display (HMD). Specifically, a marker is set on the HMD, and the position of the marker is monitored. From the position information, the image viewed by the wearer of the HMD is calculated independently for the left and right eyes, and finally the calculated 3D image is displayed on the display monitor of the HMD.

  A prototype-less system in which the wearer verifies and evaluates this 3D image as a full-scale virtual image, and an MR system that verifies and evaluates the image captured by the image monitor mechanism mounted on the HMD and the virtual image (mixed) & Reality System) has been devised as a general commercial virtual reality system.

  Such a commercial HMD requires a wide viewing angle and high resolution, and a heavy HMD as shown in Patent Document 1 is generally used. On the other hand, in recent years, methods have been proposed in which a display device made for a mobile phone or a display screen of a mobile phone as shown in Patent Document 2 is used as an HMD display screen. In Patent Document 2, a mobile phone display screen is installed in front of an HMD eyepiece, and a mechanism for directly operating the mobile phone is provided on the HMD frame. When the mobile phone is attached to the HMD frame, the mechanism is used. Various image display operations can be performed on the frame. Since the display screen of a mobile phone that is mass-produced as a consumer product and sold at low cost is used, a wide viewing angle and high-resolution HMD can be provided at low cost.

  However, as shown in FIG. 22A, various problems also occur when the mobile phone display device or the mobile phone 100 is attached in front of the eyepiece 101. The first problem is the position of the center of gravity as the HMD. The mobile phone 100 incorporates many functions, and its weight is about 150 g for a high resolution and large screen. The focal length of the eyepiece 101 for viewing this large screen needs to be 40-50 mm. Considering the thickness of the eyepiece 101 and the distance (eye relief) between the eyeball 102 and the eyepiece 101 surface, A size of about 100 mm is required. The weight of the HMD itself reaches about 300 g when combined with a mobile phone.

  As for the wearing method, it is difficult to support only the ear and nose like glasses. As shown in FIG. 22B, the sponge part 103 attached to the HMD body 104 is adhered to the face with a band 105 like goggles. It is necessary to let Since general goggles are 100 g or less, there is little effect even if the center of gravity is in front of the face, but as shown by the white arrow in FIG. If worn, the burden on the neck becomes very large.

  In order to solve the problem of the center of gravity as much as possible, a pad 106 and a rigid frame 108 extending along the head are fixed to the HMD main body 104 and fixed to the frame 108 by tightening from above the head. It has been devised to install the member 107 to a certain degree of weight so that the sum of the weights (dotted arrows) divided before and after the head is improved in the direction of the neck as much as the center of gravity of the white arrow. However, with this structure, a new problem arises that the rigid frame portion itself becomes a new heavy object, and the entire HMD becomes heavy.

  The second problem is dealing with people wearing glasses. In recent years, work using a PC has increased and the number of people wearing glasses has increased. When the HMD is worn while wearing glasses, a big problem occurs. When binoculars are used while wearing glasses, it is necessary to take an eye relief of 15 mm or more. When the same viewing angle is secured when the eye relief is long, it is necessary to increase the diameter of the eyepiece. However, this makes the eyepiece heavier, and the mobile phone is further away from the eye, further exacerbating the first problem.

  As a method of avoiding this, it is possible to remove the glasses and mount a mechanism for adjusting the focus on the HMD itself, or to exchange the eyepiece itself for the person. However, some people wearing glasses have different vision on the left and right, and people with astigmatism, so not all can be adjusted properly. Ideally, it is desirable to be able to wear the HMD while wearing glasses.

  A third problem is how to attach the HMD to the face in an oval shape with a band such as goggles. When the HMD is brought into close contact with the face, a sponge-like material is often used for the close contact portion in order to enable fine adjustment of safety and position. However, the face is easy to sweat and the sponge absorbs the sweat, which is not preferable for hygiene. In addition, since the close contact portion is elliptical and the air inside is stagnant, there is a problem that the eyepiece becomes cloudy due to sweat. Furthermore, there is a problem in that external information cannot be obtained while wearing and the HMD must be removed each time information is required.

  The fourth problem is the peculiarity of the mobile phone installed in the HMD. When a mobile phone is to function as an HMD display screen, it is detected that the mobile phone is attached to the HMD main body, and the mobile phone function is switched to the HMD image display function so that the mobile phone screen can be operated from the HMD main body. . However, this function is originally unnecessary for a mobile phone alone, and the mobile phone installed in the HMD must be a special dedicated one. For a user, it is necessary to purchase a new mobile phone, and using a mobile phone does not provide an inexpensive HMD.

  The fifth problem is difficulty in diverting to commercial HMD. As described above, as described above, it is necessary to convert to a 3D image using a high-speed PC on the basis of information of a high-precision motion capture system, and to sequentially display the result on the HMD screen in real time. In addition, since the HMD is viewed by magnifying the screen with an eyepiece, 1k (high-definition 1960 × 1080 pixels) is insufficient, and 2k and 4k display screens are required.

  However, since the display screen of the original mobile phone is viewed without using an eyepiece, for example, a mobile phone having a 5-inch display screen has a display function of 1k level, so that the display pixel becomes finer than visual acuity. , You can see clear images without problems. The image data may be received over time and stored in the memory of the mobile phone, and then the image data may be displayed, and it is not necessary to receive the data at high speed. Therefore, it is difficult to use a mobile phone having only a normal mobile phone transmission / reception function for a commercial HMD.

  The present invention has been made in view of the above problems, and an object thereof is to provide a head mounted display device that solves the first to fifth problems.

  In a first embodiment for solving the above problem, in a head-mounted display device of a type in which an image of an image output unit is directly viewed with both eyes through an eyepiece, a main body having an image output unit and an eyepiece unit Part, a mounting part for fixing the main body part to the head part, and a weight canceller part for distributing the weight of the main body part behind the head part, and the main body part and the weight canceller part are coupled by a cable. The cable can move independently with respect to the mounting portion.

  This is a method for solving the first problem in the problem, and will be described using the side view of the HMD in FIG. As shown in FIG. 1A, the problem is solved by connecting the weight canceller 2 corresponding to the weight of the HMD main body 1 with a cable 3 so that the position of the center of gravity is close to the position of the neck in total. The cable 3 may be a single-line synthetic fiber such as nylon or fluorocarbon as typified by fishing lines, or a knitting thread called a PE line with higher strength. The tensile strength is very high, it can be adapted to various shapes of the head, and the weight is almost negligible.

  Further, if it has a very high tensile strength and can conform to various shapes of the head, a belt-like belt-like structure may be used and the cable 3 can be applied.

  Since the weight canceller 2 is disposed behind the back of the head, it is desirable that the weight canceller 2 has as high a specific gravity as possible and a small volume. As a generally considered material, lead having a specific gravity of 11.34 is inexpensive, but the specific gravity of tungsten is 19.3, and the volume can be further reduced. Since the weight canceller 2 is also arranged along the head, the weight canceller 2 is divided into a plurality of parts in FIG. Note that the battery of the image output unit may be used as a weight canceller for a commercial HMD.

  A guide 5 for the cable 3 is attached to the belt 4 along the head to prevent the cable 3 from coming off the head. Further, there is a predetermined friction between the cable 3 and the guide 5, and even if there is a difference in the weight of the main body 1 and the weight canceller 2, the positional relationship does not shift in the normal way of moving the face due to the friction. .

  With this configuration, the weights of the HMD main body 1 and the weight canceller 2 are evenly distributed along the belt 4 and supported by the entire head. As a result, by supporting the weight locally at the head, there is no problem that pain or red marks remain in the local area.

  In addition, the HMD main body 1 can be stably fixed to the head by installing the member 6 for suppressing the shift in the front and rear, right and left directions and the rotation direction of the HMD main body 1 and the belt 7 along the forehead. It becomes possible. FIG. 1B shows a side view and a top view of the HMD, and shows the state in which the member 6 and the belt 7 are coupled in the vicinity of the ear and the principle that the HMD main body 1 can be stably fixed.

  In FIG. 1B, when the weight of the HMD main body 1 is M, there is a vector Mg in the direction of gravity. In order to support the weight, a pulling force vector Ft is generated in the pulling direction of the cable 3. Furthermore, the HMD main body 1 is supported by a member 6 in addition, and a force in the direction of compressing the member 6 and a vector Fa are generated. Here, the resultant force of the vector Ft and the vector −Fa pushed back by the member 6 is balanced with the vector Mg. The force in the direction of compressing the member 6 is transferred to the belt 7 in the vicinity of the joined ear, and is replaced with the tensile force Fb of the belt 7. Like the belt 4, this is a structure that is evenly distributed over the forehead along the forehead. By supporting the weight at the local part of the forehead, there is a problem that the pain and red marks on the local area remain. Does not occur.

The member 6 only needs to be rigid enough to suppress the shift in the front-rear and left-right directions and the fluctuation in the rotation direction of the HMD main body 1. By pulling up the vicinity of the extension line of the center of gravity shown by the cross of the HMD main body 1 with the cable 3, the front-rear and left-right shifts and fluctuations in the rotation direction of the HMD main body 1 can be further suppressed. In this way, since it is not necessary to directly support heavy objects, higher rigidity is unnecessary. Therefore, these members 6 may be formed of relatively lightweight members. A candidate for the belt 7 is a high-density polyethylene plate or the like, which has high tensile strength and can change its shape along the forehead.

  The belt 7 has a high tensile strength and can be changed in shape along the forehead, that is, the same effect can be obtained even if the tensile strength is increased by attaching the cable 3 to low density polyethylene, rubber or sponge. There is.

  2A to 2C show an example in which the cables 3a and 3b to be pulled up are divided into two. 2A shows a case where the face is tilted rightward, FIG. 2B shows a state where the face is not tilted, and FIG. 2C shows a case where the face is tilted leftward. Yes. The center of gravity HMD-G of the cross-shaped main body portion 1 exists on the extension line of the cable 3. Therefore, when the face is not tilted, it is supported by both cables 3a and 3b, so that no lateral force is generated. Moreover, in the state of Fig.2 (a), since it mainly supports with the cable 3a, the force to a side does not generate | occur | produce. Moreover, in the state of FIG.2 (c), since it mainly supports with the cable 3b, the force to a side does not generate | occur | produce. As described above, the HMD main body 1 and the weight canceller 2 are divided and fastened in two directions with different angles passing over the head, so that even when the face is tilted to the left and right, the HMD main body 1 is stably provided. It is a structure that can support.

  2D and 2E illustrate the case where the face is directed downward and the case where the face is directed upward. When the face is turned downward as shown in FIG. 2D, the angle formed by the pulling force vector Ft and the gravity vector Mg is expanded in the pulling direction of the cable 3, and when the angle exceeds 180 °, the member 6 is compressed. The force vector Fa in the direction to be reversed is now reversed to the pulling vector. In this case, the belt 7 in the forehead is useless and is supported by the belt 7 on the rear side of the head. On the other hand, when the face is turned up as shown in FIG. 2E, the bag portion 2a holding the weight canceller 2 is separated from the head. Here, the belt 7 on the rear side of the head, the belt 7 directed toward the neck, and the belt 7 extending toward the back of the head play a role of supporting the bag portion 2a so as not to be separated from the head.

  Next, in the second embodiment, the cable is arranged so as to be movable along a guide part installed on the head, and the weight canceller part can be moved along with the movement of the main body part. It is characterized by.

  In the third embodiment, in a head mounted display device of a type in which an image of the image output unit is directly viewed with both eyes through an eyepiece, the main body unit having the image output unit and the eyepiece unit, It is characterized by having a mounting part for fixing the main body part and a drive part fixed to the mounting part and for driving the main body part so as to be out of line of sight of both eyes.

  In a fourth mode, the driving unit includes a telescopic mechanism that changes a distance between both eyes and the eyepiece lens, a rotating unit that retracts the main body unit from the front position of both eyes in the head direction, and a predetermined position. It has the fixing mechanism which fixes the said drive part.

  The second to fourth modes are methods for solving the second and third problems, and the specific contents will be described with reference to the side view of the HMD in FIG. FIG. 3B shows a state where the image monitor unit is viewed with normal naked eyes. Here, the distance between the pupil position of the eyeball 102 and the eyepiece 9 is defined as an eye relief L1. In general, the eye relief is often about 2 mm to 8 mm when the eye is naked. If the eye relief is short, the viewing angle widens, and the viewing angle narrows as the eye relief increases. If the HMD main body 1 is mounted with glasses on as shown in FIG. 3A, the eye relief L2 needs to be at least about 15 mm.

  As a method for enabling this, in the present invention, as shown in the fourth embodiment, the stretchable portion 10 is provided in the member 6. The eye relief can be freely changed from L1 to L2 by expanding / contracting the expansion / contraction part 10. This stretchable part is provided with a one-touch stopper (not shown) and can be fixed at an arbitrary length. However, as described above, the HMD main body 1 is supported by the member 6 and the cable 3, and even if the length of the member 6 changes, the position of the HMD main body 1 can be changed if the length of the cable does not change. I can't. Therefore, the cable 3 and the weight canceller 2 are configured to move according to the position change of the HMD main body 1 as indicated by an arrow. This part is the description of the second embodiment.

  This is the same principle that the balance can be maintained even if the elevator moves up and down. Even if the HMD main body 1 moves, the weight canceller 2 and the HMD main body 1 always balance, and the stability of the HMD main body 1 becomes stable. Can be fixed. These become the eye relief variable mechanism and can solve the second problem.

  Next, the third embodiment will be described with reference to FIG. As shown in FIG. 1B, the member 6 and the belt 7 are coupled in the vicinity of the ear, but a rotating mechanism 11 that rotates the member 6 around the coupling position of the member 6 and the belt 7 is installed at that portion. Has been. By rotating the member 6 by θ, the HMD main body 1 is also rotated and lifted upward according to the length of the member 6. As described above, since the cable 3 is movable and has a structure that balances with the weight canceller 2, it can be easily lifted from the hand. With the rotation of approximately θ = 25 °, the HMD main body 1 that was in front of the eyeball 102 is eliminated, and the situation of the outside world can be easily grasped.

  The rotation mechanism can rotate from 0 to 25 °, but further movement is limited by a stopper (not shown). Thereby, even when the cable 3 is cut, the HMD main body 1 is prevented from being lowered below the position of the eye only by changing the center of gravity of the HMD from the vicinity of the neck to the front of the eyeball 102. As described above, the HMD main body 1 is held only by the cable 3 and the member 6, and it is not necessary to cover the eyes with an elliptical shape like goggles. Furthermore, since the HMD main body 1 can be easily moved from the front, it is possible to eliminate air stagnation, wipe off the sweat of the face, and easily grasp the situation of the outside world. The problem can be solved.

  In the fifth embodiment, the image output unit of the main body unit is detachable, and has an adjustment mechanism that adjusts the position of the image output unit so that the center of the image output unit coincides with the image output unit having a different shape. It is characterized by things.

  FIGS. 4 and 5 are a front view and a side view showing how the cellular phones 12a and 12b having different sizes are mounted on the eyepiece lens installation unit 13. FIG. FIG. 4D shows a 6-inch mobile phone having a large size, and FIG. 5D shows a 5-inch mobile phone having a small size. Each mobile phone has a different size. When the mobile phone 12a is fixed to the mobile phone fixing portion 14 shown in FIG. 4 (c), the mobile phone 12a is inserted from the side along the position fixing pins 15 installed at three locations. The mobile phone 12 a can be fixed by the holding spring 16. Since it is a three-point support with two points on the lower side where gravity is applied, the structure is less likely to cause backlash.

  On the other hand, since the mobile phone 12b has a different outline size, it cannot be fixed to the mobile phone fixing part 14 as it is. Therefore, as shown in FIG. 5C, the position fixing pin 15 is removed from the mobile phone fixing portion 14, and the washer 17 is fitted into the position fixing pin 15 and returned. The washer 17 is designed with a width that allows the size of the mobile phone 12b to be fixed from above and below. When the washer 17 is fixed to the mobile phone fixing portion 14, the mobile phone 12b is inserted from the side along the washer 17 and is carried by the restraining spring 16. The telephone 12b can be fixed.

  FIG. 4B and FIG. 5B both show an eyepiece lens installation portion 13 in which an eyepiece lens 9 is installed from the main body 1. The eyepiece lens installation unit 13 has a structure in which the movement guide 18b of the mobile phone fixing unit 14 can be fitted along the fixed guide 18a from the direction of the arrow in the side view, and can be placed at an arbitrary position by a stopper (not shown). It has a structure that can be fixed. People who wear glasses may want to take off their glasses and enjoy a video with a large viewing angle in the naked eye condition, so this adjustment unit can be used to change the distance between the eyepiece and the display surface of the mobile phone. The near-sighted person can focus with the naked eye. A combination of all the above mechanisms corresponds to the HMD main body 1, and the state when docked is shown in FIGS. 4 (a) and 5 (a).

  In this way, the position in the vertical direction can be easily adjusted even with a mobile phone having a different size by simply replacing an inexpensive washer. On the other hand, although it is a horizontal direction, of course, the same position fixing pin can be installed and fixed in the direction opposite to the insertion direction. However, in many cases, the display of a mobile phone is attached at a slightly asymmetric position in the long side direction, with the appearance and the display position being symmetrical in the short side direction. In the present invention, even after docking, it is easy to touch the mobile phone while looking at the display surface of the mobile phone, so that the mobile phone can be adjusted by sliding it sideways so that the center position matches. ing.

  Next, in a sixth embodiment, in a head mounted display device of a type in which an image of the image output unit is directly viewed with both eyes through an eyepiece, a main body having an eyepiece unit and an electronic device necessary for image output are provided. An image output unit having a device is configured to be detachable from the main body unit. The image output unit includes a fixing means for fixing a mobile phone having a panel resolution of 1k or more, and an application for the mobile phone. It is characterized by the fact that an electronic device is installed.

  The sixth embodiment will be described with reference to FIG. FIG. 6 is a front view and a side view showing how the mobile phone 12a is mounted on the mobile phone fixing portion 14a. FIG. 6C shows a mobile phone 12a. Here, in order to fix the mobile phone 12a, the mobile phone fixing portion 14a is used. The mobile phone fixing portion 14 a inserts the mobile phone 12 a from the side along the position fixing pins 15 installed at three locations, and fixes the mobile phone 12 a by the restraining spring 16. The structure for fixing to the fixing guide 18a of the eyepiece lens installation unit 13 using the movement guide 18b of the mobile phone fixing unit 14a is the same as that of the mobile phone fixing unit 14. The difference is that an electronic device necessary for image output of the mobile phone 12a is installed on the mobile phone fixing portion 14a.

  FIG. 6B shows an electronic device arranged on the mobile phone fixing unit 14a. The USB transmitting / receiving device 19 for connecting the USB terminal 20 to the mobile phone 12a and responding to the electronic device supplies the output of the triaxial accelerometer 21 on the mobile phone fixing unit 14a and the power supply from the mobile phone 12a to the electronic device. Do. Further, it plays a role of transmitting image data from the left and right USB cameras 23 installed on the extension line of the eye position to the mobile phone 12a. Further, a USB terminal 24 is installed on the mobile phone fixing part 14a. This can be connected to an external battery by wire, and has a structure in which power can be supplied as necessary when the battery capacity of the mobile phone 12a decreases.

  Further, by connecting a controller (not shown) from the outside to the USB terminal, the screen operation on the mobile phone 12a can be easily performed. A wide range of controllers are available, from game controllers to wired and wireless mice. FIG. 6A shows a state when the mobile phone 12a is connected to the mobile phone fixing portion 14a.

  Similarly to the mobile phone fixing unit 14, the mobile phone fixing unit 14a can fix mobile phones of various sizes by using the washer 17. Since the place where the USB is connected is different for each mobile phone, the USB terminal 20 can be routed with a cord so that the USB connection can be made with any mobile phone. Since the output result of the triaxial accelerometer 21 is sent to the mobile phone 12a as angular displacement information corresponding to the orientation of the face of the wearer wearing the main body 1, the 3D image display application software of the mobile phone 12a is used. The virtual image of the wearer's line-of-sight direction can be displayed as an image.

  The image data from the left and right USB cameras 23 is transmitted to the mobile phone 12a and is displayed as an image of the left and right eyes, but a virtual image in the gaze direction of the wearer using the above-described 3D image display application software is superimposed. If displayed as an image, it is also possible to easily enjoy MR (mix & reality) images.

  Thus, since the mobile phone fixing unit 14a is completely electrically independent from the eyepiece lens installation unit 13 that is attached to the wearer as an HMD, a developer who develops an application for a mobile phone can also use the mobile phone. By purchasing only the fixed portion 14a, it is possible to develop application software using various mobile phones without wearing the HMD for a long time.

  In addition, the mobile phone fixing portion 14a can be completely separated from the eyepiece lens installation portion 13 that is always worn by the wearer as the HMD main body portion 1. Wear the HMD, set any mobile phone to 3D image mode (display the same two images centered on a position 62 mm away from the left and right), and place it on the image plane of the eyepiece lens setting unit 13 as shown in FIG. If you bring it, you can easily reproduce what you see on the HMD. When purchasing a mobile phone, the resolution of the mobile phone is the size of the display, and the appearance when the HMD is installed also changes, so it is possible to give an indication of the model to be purchased. In this way, the fourth, fifth, and sixth forms are all useful for solving the fourth problem.

  In a seventh aspect, the image output unit is a detachable mobile phone having a panel resolution of 1k or more, a wireless receiving unit that wirelessly receives an image drawn by an external PC, and the image is transmitted to the mobile phone. It is characterized by having a wiring portion to be displayed. However, since an external PC is used in this case, the image output unit can be replaced with an image display panel having a resolution of 1k or more and its control driver instead of a mobile phone.

  Using an external commercial motion capture system, a marker is set on the HMD and the position of the marker is monitored. The high-speed image processing PC installed outside calculates and displays the image viewed by the wearer of the HMD for the left and right eyes independently from the position information. A prototype-less system in which the wearer verifies and evaluates this 3D image as a full-scale virtual image, and an MR system that verifies and evaluates the image captured by the image monitor mechanism mounted on the HMD and the virtual image (mixed) & Reality System) can be realized in the seventh embodiment.

  FIG. 8B shows an electronic device arranged on the mobile phone fixing unit 14b. The high-speed image transmission / reception control device 25 receives 3D image data having a resolution of 1k to 4k for high vision from the above-described high-speed image processing PC. When the high-speed image transmission terminal 26 of FIG. 8C is connected to the connectable mobile phone 12c, 3D image data of the external PC is sent to the mobile phone 12c via the high-speed image transmission terminal 26 in real time. On the screen of the mobile phone 12c, a moving image that can be verified and evaluated by the wearer is displayed as a full-scale virtual image. The high-speed image transmission / reception control device 25 is supplied with power from the mobile phone 12 c via the high-speed image transmission terminal 26.

  As another usage, the image data captured by the left and right USB cameras 23 installed on the extension line of the eye position is transmitted from the high-speed image transmission / reception control device 25 to the external PC in real time. The external PC that has received this fuses the image captured by the USB camera 23 and the virtual image, and transmits the fused image to the high-speed image transmission / reception control device 25 again. The high-speed image transmission / reception control device 25 transmits the 3D data. Receive. The received data is sent to the mobile phone 12c via the high-speed image transmission terminal 26. On the screen of the mobile phone 12c, a moving image that can be verified and evaluated by fusing a real image and a virtual image is displayed.

Furthermore, a USB terminal 24 exists on the mobile phone fixing unit 14b. This can be connected to an external battery by wire, and has a structure in which power can be supplied as necessary when the battery capacity of the mobile phone 12c decreases.
Further, by connecting an external controller (not shown) to the USB terminal 24, the screen operation on the mobile phone 12c can be easily performed. A wide range of controllers can be used, from game controllers to wired and wireless mice. FIG. 8A shows a state when the mobile phone 12c is connected to the mobile phone fixing portion 14b.

  Similarly to the mobile phone fixing unit 14, the mobile phone fixing unit 14 b can fix mobile phones of various sizes by using the washer 17. Since the place where the high-speed image transmission terminal 26 is connected is different for each mobile phone, the high-speed image transmission terminal 26 can be routed by a cord so that the high-speed image transmission terminal 26 can be connected to any mobile phone. By implementing the seventh embodiment, the fifth problem can be solved.

  However, a terminal of a general mobile phone is an HDMI (registered trademark) for image output to the outside or a USB terminal. Therefore, in order to realize the above system, it is necessary to use a mobile phone equipped with an image input HDMI (registered trademark) or a USB terminal. Since a system using an external PC is generally commercial, it may be replaced with an image display panel having a resolution of 1k or more and its control driver instead of a mobile phone. Since the control driver of the image display panel has an HDMI (registered trademark) or USB terminal for image input, 3D data can be received directly from the high-speed image transmission terminal 26.

  Next, the eyepiece lens shape of the eyepiece unit will be described. In an eighth aspect, the eyepiece of the eyepiece unit is a high refractive index plastic lens, and is an aspherical surface having a conic constant of at least one of the lens surfaces of less than 0, and from the eyepiece unit to the eyepiece It is characterized by being removable. Each of FIGS. 9 to 12 discloses a ray diagram (upper left), a numerical value (upper right), distortion (lower left), and a spread of rays at the image point as one set. The lens is evaluated in the aberration state when the eye relief is changed from 2.25 mm → 7.25 mm → 15 mm and the aberration state when the line of sight is tilted by a predetermined angle (the line of sight angle).

  FIG. 9 shows a first embodiment of the eyepiece. A high refractive index plastic (refractive index 1.74) is used for the eyepiece. The eyepiece diameter is 36 mm and both surfaces are composed of aspherical surfaces with a conic constant of less than 0. Even if the eye relief is separated by a distance of 15 mm with glasses, and the line of sight is directed toward the periphery of the lens, it is indicated by a circle. In the same way, high resolution can be obtained.

  FIG. 10 shows a second embodiment of the eyepiece. A high refractive index plastic (refractive index 1.74) is used for the eyepiece. An eyepiece lens diameter of 46 mm is realized. Both surfaces are composed of aspherical surfaces with a conic constant of less than 0. Even if the eye relief is separated by a distance of 15 mm with glasses, and the line of sight is directed toward the periphery of the lens, the resolution is high, as indicated by ○. Can get. In addition, a viewing angle of 120 ° with the naked eye and 92 ° with glasses is secured.

  FIG. 11 shows a third embodiment of the eyepiece. A high refractive index plastic (refractive index 1.74) is used for the eyepiece, but two lenses are used. When the display is focused after realizing the eyepiece lens diameter of 41.7 mm, the optical performance higher than those of Examples 1 and 2 is satisfied. One surface of the lens is composed of an aspheric surface having a conic constant of less than 0. As indicated by ◯, even if the eye relief is separated by a distance of 15 mm with glasses, and the line of sight is directed toward the lens periphery, A viewing angle of 114 ° with the naked eye and 90 ° with glasses is secured.

  FIG. 12 shows a fourth embodiment of the eyepiece. A high refractive index plastic (refractive index 1.74) is used for the eyepiece, but two lenses are used. The conic constant of the three lens surfaces is composed of an aspheric surface with less than 0. After realizing an eyepiece lens diameter of 50 mm, the optical performance is almost the same as in Examples 1 and 2, as indicated by ◯. . This ensures a viewing angle of 120 ° with the naked eye and 100 ° with glasses.

  Next, FIGS. 13 to 15 show a state in which an eyepiece lens is attached to the eyepiece lens installation unit 13. FIG. 13 shows a front view from the eyepiece lens mounting surface side of the eyepiece lens installation portion 13 and a side view thereof. Two openings 28 for viewing images are provided on the eyepiece lens installation unit 13 corresponding to both eyes. Fixed guides 27 for fixing the eyepiece lens are provided above and below each opening, and a groove 31 is formed so that the nose and the eyepiece lens installation portion 13 do not interfere with each other.

  FIG. 14 shows front views of eyepiece units 29a, 29b, 29c, and 29d in which the lenses of Examples 1 to 4 are placed in the lens barrel. The movement guide 30 is provided in the same dimension position so that it can fit in common. FIG. 15 shows a side view of the eyepiece unit 29a, 29b, 29c, and 29d fitted in the eyepiece lens installation unit 13. Since the eyepieces 29 having various viewing angles can be used as a common HMD, it is possible to supply HMDs that are inexpensive and compatible with multiple functions.

  Each eyepiece unit 29 is fitted along the fixed guide 27 from the side, but the eyebrow adjustment can be performed by slightly shifting the position to the left and right. The eyebrow adjustment does not need to be adjusted if a white line is normally seen on a mobile phone screen when a white vertical line 62 mm away is seen. However, if the white line appears to be separated into red, blue, and green, it means that the eyes are not right. Therefore, by moving the eyepiece unit 29 slightly to the left and right, you can find a position that can be recognized as a white line. It ’s fine. Further, since the focal lengths of the eyepieces are not common, the movement guide 18b of the mobile phone fixing unit 14 may be adjusted by moving along the fixing guide 18a of the eyepiece lens installation unit 13. By adjusting the focus and focus properly, you can obtain a highly immersive image.

  The first and second embodiments of the eyepiece described above are composed of one lens, and the third and fourth embodiments are composed of two lenses including one concave surface. ing. These can provide images with a high immersive feeling by performing the above-mentioned eyebrow adjustment. However, the eyebrow adjustment mechanism requires a mechanism for moving both eyes simultaneously to the left and right, which is one of the causes that make the eyepiece unit 29 heavy. is there. If eyebrow adjustment is not performed, there is an individual difference of about ± 8 mm centered on about 62 mm as shown in FIG. 16, so that the center of the eyepiece and the center of the eye are shifted.

  FIG. 17 shows the aberration when the center of the lens and the center of the eye are deviated from the second embodiment (corresponding to the position shift amount in the figure). The aberration shape when the amount of deviation changes in the vertical direction, the aberration shape due to the line-of-sight angle is shown in the horizontal direction, and the amount of aberration that occurs when viewed with the right eye is divided into red, green, and blue. (However, since this is the amount of aberration when the light beam enters from the direction of the eye, the red and blue directions actually appear reversed). It can be seen that the aberration increases at a position where the viewing angle is large according to the amount of deviation.

  In order to solve this problem, the eyepiece lens is composed of at least two lenses, and at least three or more aspherical surfaces (convex surfaces) having a conic coefficient of less than 0 and the remaining one surface are configured to be flat or convex. It is desirable to do. If the curvature of one surface is large, a large aberration occurs when the center of the eyepiece lens and the center of the eye are deviated, so that the use of a plurality of lens surfaces with loose curvature is more resistant to displacement. Further, if the conic constant is set to less than 0 on only a part of the lens surfaces and the numerical value is increased, the aberration also increases with respect to changes in the viewing angle and eye relief. However, since aspherical processing is expensive when glass is used, we would like to use a plastic material that can be processed to match the aspherical stencil, but general plastic materials have a low refractive index and design a lens with a wide viewing angle. Things are difficult.

  Therefore, as another method of the eighth embodiment, at least two lenses using a high refractive index plastic (refractive index of 1.74 or more) are used, and at least 3 aspherical surfaces having a conic coefficient of less than 0 are used. The convex surface above the surface and the remaining one surface are flat or convex. With this combination, even if the eye relief changes as shown in FIG. 18, it is possible to provide an eyepiece with a small amount of aberration even if the center of the eyepiece is shifted from the center of the eye. Along with the weight reduction of the lens unit 29, the mechanism can be simplified.

  FIG. 18 shows the aberration due to the position shift amount in the case of using an eyepiece constituted by one lens in the second embodiment. It can be seen that when the eye relief is moved to a distance of 15 mm with glasses, not only the image becomes invisible at a viewing angle of 30 ° (indicated by ×), but also a large aberration occurs in the positive direction of the shift amount. Even if two lenses are used, there is a large aberration when one surface is formed as a concave surface. Even in the case of an eye relief of 15 mm using a lens composed of two lenses in the fourth embodiment, the amount of aberration due to the amount of position shift is large, and a portion where an image cannot be seen at a viewing angle of 40 ° (indicated by ×) occurs. ing.

  In FIG. 18, as an eighth form, a fifth embodiment of an eyepiece in which one surface is a flat surface and the remaining three surfaces are aspherical surfaces having a conic coefficient of less than 0, the first surface is convex and the remaining three surfaces are A sixth example of an eyepiece constituted by an aspheric surface having a conic coefficient of less than 0 is shown. Simulation was performed under the condition of eye relief of 10 mm with the naked eye and a distance of 15 mm of eye relief with glasses. In both cases, the aberration due to the amount of position shift is small, and an image can be seen even with a viewing angle of 40 °. . In other words, if the fifth and sixth embodiments are used, a clear image can be seen without performing eyelid adjustment.

  However, even when the eyepieces of the fifth and sixth embodiments are used, when the amount of position shift increases, the distortion and the amount of chromatic aberration occur asymmetrically to the left and right with respect to the lens center. FIG. 19 shows aberrations under the 6 conditions of 2 × 3 of eye relief 10 mm and 15 mm, position shift amount −4 mm, 0 mm, and 4 mm when the lens of Example 5 is used (however, this is shown in FIG. 19). Is the aberration when the light beam enters from the direction of the eye, so in reality, the red and blue directions appear to be reversed). Although the vertical direction is axisymmetric, it is omitted, but it can be seen that the left and right distortions and chromatic aberrations are asymmetric in all cases compared to the shift amount of 0 mm.

  However, this distortion and chromatic aberration are generally image processed so that there is no problem in appearance by correcting the position of the image data for each RGB when the position shift amount is 0 mm. Therefore, in the ninth embodiment, distortion and chromatic aberration generated according to a plurality of position shift amounts are stored as first information, and the stored first information is stored according to the wearer's second information. Based on this, image processing was performed. The second information relates to the presence / absence of eyeglasses and eye luck.

  Regarding the presence / absence of wearing glasses, the amount of expansion / contraction of the expansion / contraction part 10 may be automatically measured, or the wearer may input the information directly. However, since there are many cases where it is not generally understood about the eyelids, it is only necessary to show the wearer the image information corrected by the stored first information and to select the image information with little chromatic aberration and small distortion. For example, image data having a position shift amount of −4 mm to 4 mm (each of RGB positions of the image in FIG. 19 is measured and displayed as spot data of the color at that position) is displayed discretely. Of course, each data may be interpolated and displayed as continuously changing image information. Since this data is displayed by reversing the red direction and the blue direction from the actual appearance, when the wearer looks at the image data that fits his eyes, the RGB data match and appear white. If you can see the white spot data no matter where you look, you are in good luck.

  As can be seen from FIG. 19, the size of RGB spots appears to be different for each color in the vicinity. Since the human eye is most sensitive to green, lenses are often designed based on green. Under this condition, the wavelength of light is greater in red than in green and in blue rather than red, so that the spot is likely to appear thicker and thicker than green. If the spot size and shape are different, it may not look white even if the colors overlap. Since the difference in size and shape of the spot is also known in advance in the first information, if the spot size of green and red overlaps with the same size and shape as blue, the spot position It becomes easy to confirm the match.

  Next, in a tenth embodiment, in a head-mounted display device of a type in which an image of an image output unit is directly viewed with both eyes through an eyepiece, a main body unit having an image output unit and an eyepiece unit, and the main body The image output unit is a detachable mobile phone with a panel resolution of 1k or more. Even after the mobile phone is attached to the main body, a predetermined position on the panel is touched with a finger while viewing the panel screen. It is characterized by having a touching window in the main body.

  FIG. 20 illustrates the tenth embodiment. FIG. 20 is a top view and a side view of the main body 1. The eyepiece lens installation portion 13 has a structure in which the movement guide 18b of the mobile phone fixing portion 14 can be fitted along the fixed guide 18a from the direction of the arrow in the side view, but the fixed guide 18a and the guide 18b are common. An opening 32 that is large enough to allow a finger to enter the position from below is opened.

  Usually, when light enters from here, it becomes difficult to see the screen of the mobile phone, so an elastic body 33 such as a rubber plate with a cut in the center is attached. When the mobile phone application software is started, or when the lower side of the screen of the mobile phone is touched, such as when software is stopped or software is changed, a command can be issued with the HMD attached. Since the touch is performed only on one eye side, the actual image becomes translucent, and the mobile phone software can be controlled while viewing the application image. As described above, the eighth and tenth embodiments are useful for solving the fourth problem.

  FIG. 21 is an embodiment for carrying out the invention, and shows a top view, a side view, and a front view of only a portion where the mobile phone 12a is fixed to the mobile phone fixing portion 14a. By connecting and balancing the weight canceller 2 corresponding to the weight of the HMD main body 1 with the cable 3, the position of the center of gravity in front of the eyes is brought close to the position of the neck in total. The cable 3 is a knitting yarn called a PE line. The weight canceller 2 is made of tungsten and is devised so as to be divided into a plurality of portions and to be well along the curved surface.

  A guide 5 for the cable 3 is attached to the belt 4 along the head to prevent the cable 3 from coming off the head. Further, there is a predetermined friction between the cable 3 and the guide 5, and even if there is a difference in the weight between the main body 1 and the weight canceller 2, it is possible that the positional relationship will be shifted in the normal way of moving the face due to the friction. No. The pulling force applied to the cable is distributed by the belt 4 and transmitted to the head.

  Moreover, the member 6 which suppresses the shift of the front and rear, right and left direction of the HMD main body part 1 and the fluctuation | variation of a rotation direction, and the belt 7 along a forehead are installed, and the member 6 and the belt 7 are couple | bonded in the ear vicinity, The compressive force is dispersed by the belt 7 and transmitted to the forehead. Since the belt 4 and the belt 7 support a wide area, the HMD main body can be stably fixed to the head. The belt 7 is a high-density polyethylene plate having high tensile strength and capable of changing its shape along the forehead.

  The weight canceller 2 is held in the bag portion 2a so that it can move freely. A belt 7 on the rear side of the head, a belt 7 facing toward the neck, and a belt 7 extending in the direction of the back of the head are provided. The bag part 2a is supported so as not to be separated from the head. The bag 2a may be a high-density polyethylene box, but when used in the state of watching a movie, the chair cushion may hit the back of the head. If the bag portion 2a is pushed with a cushion, the movement of the weight canceller 2 may be stopped. Therefore, it may be replaced with a hard acrylic box or the like.

  An expansion / contraction part 10 is provided in the member 6. By expanding and contracting the stretchable part 10, the eye relief can be freely changed from 2 mm of the naked eye to 15 mm when wearing glasses. This stretchable part is provided with a one-touch stopper (not shown) and can be fixed at an arbitrary length. Moreover, although this expansion-contraction part 10 is being fixed above the HMD main-body part 1 like glasses, since a balance may worsen when it faces down, you may fix in the gravity center vicinity of a HMD main-body part.

  The expansion / contraction of the expansion / contraction part 10 generates a gap between the face and the HMD main body 1, and external light is reflected from the lens surface of the eyepiece 9 in the HMD main body 1, thereby deteriorating the image appearance. There is a possibility. Since it is desirable to leave a gap to the extent that the eyepiece does not become cloudy due to sweat without stagnating the air inside, a lightweight and light-shielding member such as a foam sheet such as polypropylene is attached to the periphery of the HMD body 1, You may adjust it so that length may be changed according to the expansion-contraction of the expansion-contraction part 10, and a moderate clearance gap may be maintained.

  The member 6 and the belt 7 are coupled in the vicinity of the ear, and a rotating mechanism 11 that rotates the member 6 around the coupling position of the member 6 and the belt 7 is installed at the portion, and the HMD main body 1 is connected to the eye. It has a structure that can be evacuated from the front.

  The mobile phone 12a has a large size of 6 inches. When the mobile phone 12a is fixed to the mobile phone fixing portion 14a, the mobile phone 12a is inserted from the side along the position fixing pins 15 installed at three locations, and the mobile phone 12a is pressed by the restraining spring 16. Can be fixed. Since it is a three-point support with two points on the lower side where gravity is applied, the structure is less likely to cause backlash. When the portable size is small, a washer 17 is fitted into the position fixing pin 15 to adjust the width to be suppressed.

  An electronic device arranged on the mobile phone fixing unit 14a is shown. The USB transmitting / receiving device 19 for connecting the USB terminal 20 to the mobile phone 12a and responding sends the output of the triaxial accelerometer 21 on the mobile phone fixing unit 14a and the power supply from the mobile phone 12a to the electronic device. Do it. Further, it plays a role of transmitting image data from the USB camera 23 arranged on the left and right USB camera installation bases 22 installed on the extension line of the eye position to the mobile phone 12a. Further, a USB terminal 24 is installed on the mobile phone fixing part 14a. This can be connected to an external battery by wire, and has a structure in which power can be supplied as necessary when the battery capacity of the mobile phone 12a decreases. The cable of the USB terminal 24 may be divided into a plurality of branches so that power can be supplied to other electronic devices on the mobile phone fixing unit 14a.

  Although an external battery having a weight of 100 g to 250 g can be used instead of the weight canceller 2, the battery needs to be configured to be removable. In this case, the cable of the USB terminal 24 is extended to the back of the head along the belt 4 or the belt 7, and the cable 3 connecting the HMD main body 1 and the weight canceller 1 is a unit (not shown) for mounting a battery. ). The battery can be removed by removing the battery from the unit and disconnecting from the USB terminal 24. By attaching a battery to this unit, it becomes an alternative to the weight canceller 2. This battery can be installed as a general-purpose product, and a separate battery is prepared in advance and can be replaced stably for a long time.

  In general, a battery becomes heavier and larger in size as its capacity increases. On the other hand, a small capacity has a small capacity but is lighter and smaller in size. Since the weight canceller 2 is designed to be balanced with the HMD body 1 in weight, if a battery is used instead, a battery with a fixed weight must be used. However, it is possible to balance the weight of the unit + battery with the HMD body 1 by adjusting the weight of the unit itself using a weight such as lead, etc., by attaching a battery to the above unit. Can be used. For example, when using an HMD while sitting on a reclining chair, the weight counter 2 can be kept out of the way during reclining by using a small battery. Also, when using the HMD for a long time, it is not necessary to replace the battery for a long time by using a large battery with a large capacity.

  Further, by connecting a controller (not shown) from the outside to the USB terminal 24, the screen operation on the mobile phone 12a can be easily performed. A wide range of controllers are available, from game controllers to wired and wireless mice. The USB terminal 20 can be routed with a cord so that any mobile phone can be connected to the USB. Since the output result of the triaxial accelerometer 21 is sent to the mobile phone 12a as angular displacement information corresponding to the orientation of the face of the wearer wearing the main body 1, the 3D image display application software of the mobile phone 12a is used. The virtual image of the wearer's line-of-sight direction can be displayed as an image.

  The image data from the left and right USB cameras 23 is transmitted to the mobile phone 12a and displayed as an image of the left and right eyes. The virtual image in the direction of the wearer's line of sight using the above-described 3D image display application software is superimposed. It is possible to easily enjoy MR (mixed & reality) images.

  Thus, since the mobile phone fixing unit 14a is completely electrically independent from the eyepiece lens installation unit 13 that is attached to the wearer as an HMD, a developer who develops an application for a mobile phone can also use the mobile phone. By purchasing only the fixed portion 14a, it is possible to develop application software using various mobile phones without wearing the HMD for a long time.

  The eyepiece lens 29d is a two-lens using a high refractive index plastic (refractive index 1.74). The lens surface is composed of three aspherical surfaces with a conic constant of less than 0, realizing high optical performance after realizing an eyepiece lens diameter of 50 mm. This ensures a viewing angle of 120 ° with the naked eye and 100 ° with glasses.

  Two openings 28 for viewing images are provided on the eyepiece lens installation unit 13 corresponding to both eyes. A fixed guide 27 for fixing the eyepiece lens is provided above and below each opening, and a moving guide 30 is provided at the same size position so that the eyepiece unit 29d can be fitted in common. By shifting the movement guide 30 portion, the eyepiece unit 29d can be removed and replaced with another eyepiece. Furthermore, the groove | channel 31 is formed so that a nose and the eyepiece lens installation part 13 may not interfere.

  The focal length of the eyepiece unit 29d can be adjusted by moving the movement guide 18b of the mobile phone fixing unit 14a along the fixing guide 18a of the eyepiece lens installation unit 13. If a nearsighted person wants to enjoy an image with a wide viewing angle by removing his / her glasses, the focus can be adjusted properly in this area.

  The eyepiece lens installation portion 13 has a structure in which the movement guide 18b of the mobile phone fixing portion 14 can be fitted along the fixed guide 18a from the direction of the arrow in the side view, but the fixed guide 18a and the guide 18b are in common positions. An opening 32 that is large enough to allow a finger to enter from below is opened.

  Usually, when light enters from here, it becomes difficult to see the screen of the mobile phone, so an elastic body 33 such as a rubber plate with a cut in the center is attached. When the mobile phone application software is started, or when the lower side of the screen of the mobile phone is touched, such as when software is stopped or software is changed, a command can be issued with the HMD attached. Since the touch is performed only on one eye side, the actual image becomes translucent, and the mobile phone software can be controlled while viewing the application image.
