As the interocular distance, the distance between the centers of the pupils may be adopted, or the distance between the inner side of the right eye and the inner side of the left eye (distance between the eyes) may be adopted.
(A2) Convergence angle: The convergence angle is an angle representing a difference (binocular parallax) between an image seen by the user's right eye and an image seen by the left eye.

(A3) Relative position of the eye and the optical element: The relative distance between the eye and the optical element is, for example, a value representing a deviation between the center of the pupil and the center of the half mirror as the optical element. This value may be stored separately from left and right, or a value obtained by averaging left and right may be stored. That is, the shift between the center of the pupil of the right eye of the user and the center of the half mirror in the right light guide plate 261 and the center of the pupil of the left eye of the user and the half mirror in the left light guide plate 262 Deviations from the center of the image may be stored separately. Moreover, the value which averaged both may be memorize | stored.

(A4) Angle between the eye and the optical element: The angle between the eye and the optical element is represented by the rotation angle (θr, θp, θy) of the half mirror when the image display unit 20 is mounted on the user's head. . For example, the center of the half mirror is the origin, and the roll axis, pitch axis, and yaw axis that are orthogonal to each other at the origin are defined. In this case, the roll angle θr of the rotation angles (θr, θp, θy) is an angle formed by the optical axis direction of the half mirror and the roll axis. Similarly, the pitch angle θp is an angle formed by the optical axis direction of the half mirror and the pitch axis. The yaw angle θy is an angle formed by the optical axis direction of the half mirror and the yaw axis. The angle between the eye and the optical element can be calculated based on the measurement value of the 9-axis sensor 66.

(A5) dominant eye: The dominant eye is information representing the eye on the side often used when the user looks at an object.
(A6) Color information: Information representing characteristics of a sense (color vision) for sensing the color of the user's eyes.
(A7) Brightness: A value representing the brightness of the virtual image VI (FIG. 3) formed by the image display unit 20.
(A8) Display position adjustment: a value used for adjusting (shifting) the position of the virtual image VI (FIG. 3) formed by the image display unit 20. Note that the interocular distance of the information a1 and the convergence angle of the information a2 can be adjusted by adjusting the display position.

  A method for determining some of the information is, for example, as follows. The CPU 140 recognizes and tracks the reference real object corresponding to the image through the camera 61 while displaying the calibration image on the image display unit 20. In this state, the user UR moves the position of the calibration image on the image display unit 20 via the user interface (trackpad 14 or the like). Then, at the timing when the user UR perceives that the calibration image and the reference real object overlap each other (at least one of position, size, and orientation substantially matches) via the image display unit 20. The CPU 140 is notified via the interface. In accordance with the acquired notification, the CPU 140 can acquire a parameter corresponding to the detection result (position or the like) of the reference real object at the timing, and can determine the information based on the parameter.

  The setting writing process in FIG. 4 is executed by the cooperation of the writing unit 142 and the setting unit 146 of the HMD 100. A start trigger of the setting writing process can be arbitrarily determined. For example, the start trigger may be that initial setting processing has been performed on the HMD 100. For example, acquisition of a process start request from a user may be used as a start trigger, and acquisition of a process start request from the OS 150 of the HMD 100 or a specific application may be used as a start trigger.

  In step S100, the user UR inputs a user ID and setting information. The user ID is identification information uniquely assigned to the user UR. The setting information is the information a1 to a8 described above. In step S100, the setting unit 146 of the HMD 100 may display an input screen using a GUI (Graphical User Interface) on the image display unit 20 in order to assist input by the user UR. In addition, the setting unit 146 automatically calculates at least a part of the information a1 to a8 by using a detection value by the 9-axis sensor 66, an outside scene image acquired by the camera 61, various sensors (not shown), and the like. May be. For input by the user UR, in addition to input using various keys of the control unit 10, input using a foot switch, input using eye movement, input by gesture, and input by voice can be used.

  In step S102, the setting unit 146 of the control unit 10 acquires the user ID and setting information input in step S100. In step S104, the setting unit 146 of the control unit 10 adjusts the HMD 100 based on the setting information acquired in step S102. Specifically, the setting unit 146 uses information a1 to a8 included in the setting information as various programs (for example, the OS 150, the image processing unit 160, and other application programs) related to the formation of virtual images in the image display unit 20. Store in an appropriate location in the storage area to be referenced. Thereby, after step S104, a virtual image is formed based on the new setting information. Note that adjusting the HMD 100 based on the setting information as in step S104 is also simply referred to as “setting”.

  In step S106, the setting unit 146 of the control unit 10 guides the user UR to touch the NFC mark 19 with the card 300. This guidance may be a mode in which a guidance screen is displayed on the image display unit 20 or a mode in which guidance voices are supplied to the left and right earphones 32 and 34. In step S <b> 108, the user UR touches the NFC mark 19 with the card 300.

  In step S110, the NFC communication unit 136 of the control unit 10 detects the touch of the NFC tag of the card 300. In step S110, instead of detecting touch, it may be detected that the NFC tag of the card 300 is within the communicable range of the NFC reader of the NFC communication unit 136 of the control unit 10. In step S112, the setting unit 146 of the control unit 10 writes the setting information acquired in step S102 to the NFC tag of the touched card 300. At this time, the setting unit 146 writes the user ID acquired in step S102 in association with the device ID of the HMD 100 and the setting information. The device ID of the HMD 100 is identification information uniquely given to the HMD 100 and is stored in advance in the storage unit 120 of the HMD 100. Step S <b> 112 is executed via the writing unit 142.

  FIG. 5 is a diagram illustrating a result of the setting writing process. As a result of the setting writing process (FIG. 4), one entry (information) in which the user ID, the device ID, and the setting information are associated is added as the medium information 302 to the NFC tag of the card 300.

In the example of FIG. 5, the NFC tag of the card 300 stores the following two entries E1 and E2.
(E1) Setting information about the HMD 100 identified by the device ID “1” of the user identified by the user ID “1”.
(E2) Setting information regarding the HMD 100 identified by the device ID “2” of the user identified by the user ID “1”.

  In this way, the NFC tag of the card 300 can store a plurality of setting information for various HMDs 100 of various users by a combination of the user ID and the device ID. When the card 300 is occupied by one user, in other words, when there is no need to store setting information of a plurality of users on the card 300, the user ID may be omitted.

  As described above, according to the setting writing process of the first embodiment, the setting unit 146 closes the setting content input by the user UR to the control unit 10 of the head-mounted display device (HMD 100). Stored in the storage medium (the NFC tag of the card 300). For this reason, the setting unit 146 reads the setting contents (setting information) once performed by the user UR from the storage medium close to the head-mounted display device in the setting reading process executed after the second time. It can be easily acquired and reused.

A-4. Setting read processing:
FIG. 6 is a sequence diagram illustrating a procedure of setting read processing. In the setting reading process of the first embodiment, setting information is acquired from the NFC tag of the card 300, and the HMD 100 is adjusted based on the acquired setting information.

  The setting reading process is executed by the cooperation of the reading unit 144 and the setting unit 146 of the HMD 100. The start trigger of the setting reading process can be arbitrarily determined. For example, the start trigger may be that the HMD 100 is turned on. For example, acquisition of a process start request from a user may be used as a start trigger, and acquisition of a process start request from the OS 150 of the HMD 100 or a specific application may be used as a start trigger.

  In step S <b> 200, the user touches the NFC mark 19 with the card 300. In step S202, the NFC communication unit 136 of the control unit 10 detects the touch of the NFC tag of the card 300 (or being within a communicable range).

  In step S204, the setting unit 146 of the control unit 10 acquires the setting information by reading the medium information 302 (FIG. 5) stored in the NFC tag of the touched card 300. At this time, the setting unit 146 acquires only the setting information of the own device. Specifically, the setting unit 146 acquires only an entry in which the device ID of the medium information 302 matches the device ID of the own device stored in the storage unit 120 in advance. Step S <b> 204 is executed via the reading unit 144.

  In step S206, the setting unit 146 of the control unit 10 adjusts the HMD 100 based on the setting information read in step S204. Details are the same as step S104 of FIG. Note that when there are a plurality of setting information of the own device read in step S204, the setting unit 146 may guide the user to specify setting information to be adopted prior to step S206. This guidance may be a mode in which a guidance screen is displayed on the image display unit 20 or a mode in which guidance voices are supplied to the left and right earphones 32 and 34.

  As described above, according to the setting reading process of the first embodiment, the setting unit 146 sets, in other words, the setting related to the virtual image formation in the image display unit 20 according to the medium information 302 (FIG. 5) acquired from the card 300. Then, the setting regarding how the virtual image appears can be performed (step S204). Since the medium information 302 can be acquired from the storage medium (the NFC tag of the card 300) close to the control unit 10 of the head-mounted display device (HMD 100) via short-range wireless communication, image recognition, etc. The processing content is simple compared to the above, and the processing load in the setting unit 146 is light. Further, the unit for changing the setting relating to the appearance of the virtual image can be determined by the handling of the storage medium in which the medium information 302 is stored. For example, when the storage medium is occupied by one user, the setting relating to the appearance of the virtual image can be changed for each user. For example, when the storage medium is shared by a group, the setting relating to the appearance of the virtual image can be changed for each group. As a result, it is possible to provide a head-mounted display device that can change settings related to the appearance of a virtual image for each specific unit (unit using the card 300, such as an individual unit or a group unit) with a simple configuration. be able to.

  Further, according to the setting reading process of the first embodiment, the medium information 302 (FIG. 5) stored in advance in the storage medium (the NFC tag of the card 300) is the setting information of the HMD 100. For this reason, as described in step S204, the setting unit 146 can acquire the setting information directly from the storage medium close to the control unit 10 of the head-mounted display device (HMD 100). For this reason, even in a head-mounted display device that a user uses for the first time, and even if the head-mounted display device does not include a communication means other than short-range wireless communication, with a simple configuration, The setting relating to the appearance of the virtual image can be changed for each specific unit (unit using the card 300).

  According to the setting reading process of the modification 3, the setting information is stored in the setting information storage unit 452 provided in the head-mounted display device (HMD 100a), and the setting unit 146a receives the information from the head-mounted display device. Setting information can be acquired. As described above, since the second modification does not require connection to the information processing device, even if the head-mounted display device does not include any communication means other than short-range wireless communication, the virtual image can be generated with a simple configuration. The setting relating to the appearance can be changed for each specific unit (unit using the card 300a).

C. Variations:
In the above embodiment, a part of the configuration realized by hardware may be replaced by software, and conversely, a part of the configuration realized by software may be replaced by hardware. Good. In addition, the following modifications are possible.

・ Modification 1:
In the said embodiment, it illustrated about the structure of the video display system. However, the configuration of the video display system can be arbitrarily determined without departing from the gist of the present invention, and for example, addition / deletion / conversion of components can be performed.

  For example, the video display system may include other devices in place of or in addition to the above-described devices. For example, a personal computer, NAS (Network Attached Storage) or the like may be used instead of the server. For example, other devices (not shown) such as routers and access points may be included.

  For example, the HMD and the card of the video display system may adopt short-range wireless communication using a method other than NFC. For example, the HMD and the card can be connected to each other by using short distance wireless communication as described in the above-described embodiment by using Felica (registered trademark), Mifare (registered trademark), Bluetooth (registered trademark), TransferJET, and the like. Communication can be performed. For example, when using Felica, IDm can be used instead of UID.

  For example, an IC chip (an NFC tag in the example of the above embodiment) as a storage medium may be included in other than the card. Specifically, an IC chip as a storage medium may be embedded in a device such as a smartphone or a PDA, may be embedded in a tag seal, or may be embedded in a removable HMD component. . Removable HMD parts include, for example, HMD headbands (belts for fixing the image display unit to the user's head), HMD name tags, HMD decorative parts (members for changing the appearance) ) Etc.

  For example, as the identification information of the second embodiment, various kinds of information other than the identifier uniquely given to the IC chip at the time of factory shipment can be used. For example, a UUID (Universally Unique Identifier) added later to the IC chip may be used as identification information. Arbitrary information stored in the encryption area of the IC chip (for example, a combination of employee number, personal information, a unique value automatically generated based on the user ID, etc.) may be used as identification information.

Modification 2
In the said embodiment, it illustrated about the structure of HMD. However, the configuration of the HMD can be arbitrarily determined without departing from the gist of the present invention. For example, each component can be added, deleted, converted, and the like.

The allocation of components to the control unit and the image display unit in the above embodiment is merely an example, and various aspects can be employed. For example, the following aspects may be adopted.
(I) A mode in which processing functions such as a CPU and a memory are mounted on the control unit, and only a display function is mounted on the image display unit. (Ii) Processing functions such as a CPU and a memory are provided in both the control unit and the image display unit. Aspect to be mounted (iii) A mode in which the control unit and the image display unit are integrated (for example, a mode in which the control unit is included in the image display unit and functions as a glasses-type wearable computer)
(Iv) A mode in which a smartphone or a portable game machine is used instead of the control unit. (V) The control unit and the image display unit are connected by a connection via a wireless signal transmission path such as a wireless LAN, infrared communication, or Bluetooth. The aspect which abolished the connection part (code). In this case, power supply to the control unit or the image display unit may be performed wirelessly.

  FIG. 14 is an explanatory diagram showing an external configuration of the HMD in the modification. The image display unit 20x of FIG. 14A includes a right optical image display unit 26x and a left optical image display unit 28x. These are formed smaller than the optical member of the above-described embodiment, and are respectively disposed obliquely above the left and right eyes of the user when the HMD is mounted. The image display unit 20y of FIG. 14B includes a right optical image display unit 26y and a left optical image display unit 28y. These are formed smaller than the optical member of the above-described embodiment, and are respectively disposed obliquely below the left and right eyes of the user when the HMD is mounted. Thus, it is sufficient that the optical image display unit is disposed in the vicinity of the user's eyes. The size of the optical member forming the optical image display unit is arbitrary, and the optical image display unit covers only a part of the user's eyes, in other words, the optical image display unit completely covers the user's eyes. There may be no aspect.

  For example, the HMD is a binocular transmissive HMD, but may be a monocular HMD. For example, it may be configured as a non-transparent HMD that blocks the transmission of outside scenes when the user wears the HMD, or may be configured as a video see-through in which a camera is mounted on the non-transparent HMD. For example, the earphone may adopt an ear-hook type or a headband type, or may be omitted.

  For example, instead of the image display unit worn like glasses, a normal flat display device (liquid crystal display device, plasma display device, organic EL display device, etc.) may be employed. Also in this case, the connection between the control unit and the image display unit may be either wired or wireless. In this way, the control unit can be used as a remote controller for a normal flat display device. For example, instead of an image display unit worn like glasses, an image display unit of another aspect such as an image display unit worn like a hat or an image display unit built in a body protective device such as a helmet is used. It may be adopted. For example, you may comprise as a head-up display (HUD, Head-Up Display) mounted in vehicles, such as a motor vehicle and an airplane, or another transportation means.

  For example, the NFC mark and the NFC communication unit may be provided in the image display unit instead of the control unit.

・ Modification 3:
In the above-described embodiment, an example of the setting writing process and the setting reading process has been described. However, the processing procedure shown in the above embodiment is merely an example, and various modifications are possible. For example, some steps may be omitted, and other steps may be added. The order of the steps performed may be changed.

  For example, when a condition other than “the initial setting process has been performed on the HMD” is adopted as the start trigger of the setting writing process, step S100 may be omitted. When step S100 is omitted, in step S102, the setting unit collects setting information with reference to an appropriate location (or a plurality of locations) in the storage area referred to by various programs related to virtual image formation in the image display unit. Do.

  For example, after the setting writing process is completed, the setting unit uses the confirmation function and the editing function of the setting information written in the IC chip (NFC tag in the example of the above embodiment) as a storage medium using the HMD. May be provided to a person.

  For example, after the setting reading process is completed, the setting unit may guide the user that the setting relating to the formation of the virtual image in the image display unit is automatically performed based on the IC chip as the storage medium. Good.

  For example, in the setting writing process of the second embodiment, the setting unit may present a default value of setting information to the user. The default value may be preset in the HMD or acquired from the server. The default value acquired from the server can be obtained, for example, by analyzing the information of many users' setting information stored in the setting information storage unit of the server and collecting statistics.

  For example, in the setting reading process of the second embodiment, the server transmits “recommended setting information” instead of transmitting the search result in the setting information storage unit (step S256) or together with the transmission of the search result. May be. Recommended setting information can be obtained, for example, by analyzing information on setting information of a large number of users stored in the setting information storage unit and collecting statistics. When transmitting both the search result and the recommended setting information, the setting unit of the HMD may further inquire the setting information to be adopted from the user.
