- the image analysis unit 43 acquires eye information related to the eyes 1a and 1b of the user (step 201). Based on the acquired eye information, change of the viewing state and notification of predetermined information are executed (step 102).
- the change of the viewing state is, for example, arbitrary movement of the content viewing state such as movement of the left and right lens systems 22a and 22b, movement of the display 21, movement of the display position of the image, adjustment of the mounting band part 11, etc. Processing is included. In addition, notification of a predetermined alarm or the like can be said to be a change in the viewing state.
- FIG. 6 is a flowchart showing an example of processing performed when the use of the HMD 100 starts.
- the user turns on the power of the HMD 100
- the notification unit 50 shown in FIG. 3 notifies the user of that (Step 202).
- the notification method is not limited, and for example, sound may be output from the headphone unit 12, or predetermined color light may be output to the outside of the base unit 10 or the cover unit 14. Alternatively, processing may be performed such that the entire display 21 blinks.
- the notification to the user may be executed by the vibration of the base 10 or the like by the vibration mechanism.
- step 203 the search for the eye area of the user is started (step 203). Specifically, detection of the eye area 56 of the left eye 1 a and the eye area 56 of the right eye 1 b is executed by the image analysis unit 43 shown in FIG. 3. Then, it is determined whether the left and right eye regions 56 can not be detected at all (step 204).
- step 205 it is determined whether the HMD 100 is physically moving. This determination is performed by the state analysis unit 48, for example, based on the detection result of the 9-axis sensor.
- the proximity type camera used for fingerprint imaging etc. is provided in sensor part 31 as judgment processing of Step 205, the user's skin etc. are imaged with the proximity type camera and the movement direction and distance of the skin pattern are measured. Good. For example, it is also possible to estimate the movement distance by the cumulative movement distance from the time of calibration. Further, it may be determined whether the HMD 100 is physically moving or not based on an image captured by a camera (including an IoT or the like) placed at a distant place. For example, face detection is performed on the face to which the HMD 100 is attached, and the position of the LED marker attached to the HMD is detected. It is possible to determine whether there has been physical movement from the relationship between the face detection result and the LED markers of the HMD.
- Step 206 the process waits until the HMD 100 stops (Step 206). That is, it waits until the state of the user or the HMD 100 settles down. Then, after waiting for a predetermined time, the process returns to step 203.
- an instruction to prompt the user to change the wearing state is notified so that the left eye camera 23a and the right eye camera 23b can capture the eye 1 of the user.
- Step 207 an announcement indicating that the position of the HMD 100 should be corrected manually is output. Thereafter, the process returns to step 203.
- step 208 it is determined whether all the left and right eye regions 56 can be detected. If there is an area to be lost in the left and right eye areas 56 (No in step 208), it is estimated in which direction of the left, right, upper, and lower the HMD 100 deviates (step 209).
- the band adjustment unit 47 generates a control signal based on the amount of deviation estimated in step 209 and outputs the control signal to the band adjustment mechanism 25. That is, a control signal is output to the band adjustment mechanism 25 so that the left-eye camera 23a and the right-eye camera 23b can be used to take an image of the user's eye 1. Then, the length and the position of the temporal band 17 and the top band 18 of the mounting band 11 are changed by the band adjustment mechanism 25 (step 210).
- the length of the temporal band 17 or the like is adjusted. If it is estimated that a shift occurs in the vertical direction, the length of the top band 18 or the like is adjusted. Of course, such processing is not limited.
- the band on the temporal side described in FIG. 6 corresponds to the temporal band 17, and the band on the parietal region corresponds to the parietal band 18.
- step 211 If all the left and right eye regions 56 can be detected (Yes in step 208), setting of the initial position is performed (step 211).
- FIG. 7 is a flowchart showing an example of setting of the initial position.
- FIG. 8 is a schematic view for explaining an example of setting of the initial position shown in FIG.
- the setting of the initial position is to set the state of the user's left and right eyes 1 with respect to the image display mechanism 20 to an initial state in which contents can be appropriately viewed properly when the HMD 100 starts to be used.
- the above-described initial state in which the content can be appropriately viewed corresponds to “when the user's eye is in a predetermined state”.
- the initial state can also be said to be a predetermined viewing state.
- the reference image 60 is displayed at a predetermined position on the display 21 (step 301). For example, as shown in FIG. 8A, a point image given a predetermined color such as green is displayed as a reference image 60 at substantially the center of the display 21. Then, the left and right eye images 55 photographed in that state are analyzed (step 302).
- the reference image 60P is arranged with a predetermined size and position with respect to the left and right eyes 1P of the user. Specifically, it is determined whether the size and position of the reference image 60P are in a predetermined state (step 303).
- a predetermined state As shown in FIG. 8B, in the left and right eye images 55, it is determined whether or not the reference image 60P is displayed smallest and clearly at the center of the pupil.
- This state is a state in which the image light of the diffusely emitted reference image 60 is formed to the smallest size, and the user's left and right eyes 1 are focused on the reference image 60 displayed on the display 21.
- this state is a state in which the above-described initial state is realized.
- the left and right lens systems 22a and 22b are moved (step 304). That is, a control signal is generated by the mechanism drive unit 45 and is output to the drive mechanism 26. The drive mechanism 26 moves the left and right lens systems 22a and 22b based on the input control signal.
- the lens system 22 is appropriately moved with reference to the X, Y, and Z axes so as to be in a focused state (the state shown in FIG. 8B).
- the lens system 22 has XYZ axes so as to be in the in-focus state even when the size deviates to the left with respect to the center of the pupil. It is moved appropriately as a standard.
- any driving method capable of controlling the size and position of the reference image 60P may be performed.
- the predetermined state (that is, the initial state) of step 303 is realized when reference image 60P becomes the smallest at the center position. Good.
- the predetermined allowable range is set for the position and the size, and the size and the position of the reference image 60P are included in the allowable range, the predetermined state (that is, the initial state) of step 303 is realized. It may be determined.
- the size, the position, and the inclination of the left and right eye regions 56 are stored in the storage unit 30.
- the size (for example, the number of pixels) of the long axis 57 of the eye area 56 shown in FIG. 4 is stored as the size of the eye area 56.

Equivalent to. Further, the eye image captured in the initial state corresponds to a reference eye image.
- the shape, size, color and the like of the reference image 60 are not limited, and may be designed arbitrarily. For example, an image of a building, a vehicle or a balloon, a predetermined logo mark, or the like may be displayed as the reference image 60. Further, the conditions set for the reference image 60P in the eye image 55 and the conditions for determining that the initial state is realized are not limited. That is, conditions on the size and position of the reference image 60P may be set arbitrarily, and parameters (brightness value and blur degree) other than the size and position may be adopted as conditions on the realization of the initial state.
- a reference image 60 of a simple shape such as a point image shown in FIG. 8

- the content image or the like may be displayed at a position according to the position of the reference image 60 when the initial state is realized. .
- the setting of the initial position can be said to be setting processing of the focus and the display position before viewing the content.
- FIG. 9 is a flowchart showing an operation example of the HMD 100 after setting of the initial position. Steps 401 to 410 are substantially the same as steps 201 to 210 shown in FIG. Immediately after the setting of the initial position is completed, in most cases, the process proceeds from step 408 Yes to step 411. It is also possible that the user walks or runs within the virtual reality (VR) while viewing the content. In such a case, it is conceivable that the HMD 100 may be displaced, but execution of steps 401 to 410 can automatically advance to step 411.
- VR virtual reality
- step 411 it is determined by the shift calculating unit 44 shown in FIG. 3 whether or not the inclination of the major axis 57 of the eye region 56 is changed as compared with the inclination of the major axis 57 in the initial state.
- the display control unit 46 moves the display position of the image (content image) displayed on the display 21. Specifically, the display coordinate axis with respect to the display 21 is rotated at a rotation angle corresponding to the change of the inclination of the long axis 57 (step 412). As a result, it is possible to correct the inclination of the image generated due to the rotational displacement of the HMD 100 or the like.
- the deviation calculation unit 44 determines whether the shape, size and position of the eye area 56 change as compared to the shape, size and position of the eye area 56 in the initial state. Is determined (step 413). If there is no change in the shape, size and position of the eye area 56, the change of the viewing state is not performed, and the process returns to step 403.
- the mechanism drive unit 45 If there is a change in the shape, size, and position of the eye region 56, the mechanism drive unit 45 generates a control signal according to the change and outputs the control signal to the drive mechanism 26.
- the position and angle of each of the display 21, the lens system 22a for the left eye, and the lens system 22b for the right eye are adjusted (step 414). Specifically, the position and angle of each of the display 21, the left-eye lens system 22a, and the right-eye lens system 22b are adjusted such that the state of the user's eye 1 with respect to the image display mechanism 20 approaches the initial state. Be done.

- movement of the display 21 and the lens system 22 may be performed without using table information.
- the movement amount may be calculated by calculation each time based on the deviation amount, and the operation of the drive mechanism 26 may be appropriately controlled.
- FIG. 10 is a schematic view showing an example of movement of the lens system 22 according to the amount of deviation.
- the base 10 on which the left-eye camera 23 a and the right-eye camera 23 b are installed is moving in a direction away from the user's eye 1.
- the left and right lens systems 22 are moved closer to the user's eyes in order to correct the influence of this shift, ie, to approach the initial state.
- the base 10 on which the left-eye camera 23 a and the right-eye camera 23 b are installed is moving in a direction approaching the eye 1.

- the display 12 and the lens system 22 may be moved so that the sizes of the left and right eye regions 56 become substantially equal.
- the change of the viewing state and the predetermined notification are executed based on the eye information on the eye 1 of the user. That is, based on eye information, movement of at least a part of the image display mechanism 20, adjustment of the mounting band portion 11, and notification of predetermined information are executed. Thereby, for example, it is possible to realize a high quality viewing experience for the user who uses the HMD 100.
- movement or the like of the lens system 22 is automatically executed based on eye information on the user's eye 1 even while viewing content.
- it is also possible to correct the influence of the deviation without, for example, the user noticing, without disturbing the viewing of the content.
- Even when manual adjustment is required it is also possible to determine the amount of deviation based on eye information and to notify the user of an appropriate adjustment method. Moreover, it is also possible to notify whether it is the most appropriate position. That is, it is possible to execute an effective guide for the user.
- notification or an alert is displayed using text that is blurred or visible, an image that can be recognized even if blurred, a symbol, a mark, and the like.
- notification or alarm is executed by voice or the above-mentioned verberation or the like.
- the notification method is appropriately changed based on the measurement result. For example, processing such as emphasizing a notification to wake up, turning off content, turning off the power of the HMD 100 itself, and the like may be considered.
- the HMD 100 If it is determined that the HMD 100 is shifted to the left or right, it is possible to guide the user to move the head instantaneously using the content and to correct the shift. For example, sound is used to move the sound quickly from the right ear to the left ear. Alternatively, the display 21 displays an image moving quickly to the left and right. This content causes the user to feel that something has moved on the screen, and the user momentarily moves his head to follow it. It is also possible to guide the movement of the head by this. Furthermore, it is also possible to guide the user to move the head instantaneously using both sound and image movement.
- the HMD 100 It is also possible to correct the displacement of the HMD 100 by changing the holding force of the mounting band portion 11. For example, when one side of the mounting band 11 is loosened and the other side is closed by using a predetermined button operation from the user, head movement (acceleration application), and voice input as a trigger, the entire HMD 100 moves. It is also possible to return to the normal position.
- FIG. 11 is a flowchart showing an outline of another process that can be executed by the HMD 100.

- processing etc. which move at least one copy of image display mechanism 20 may be performed based on information different from eye information.
- information and eye information may be combined to execute the change of the viewing state and the predetermined notification. This makes it possible to realize a high quality viewing experience.
- the lens system 22 and the like are moved so as to approach the initial state when a shift occurs.
- the movement of the display 21 or the lens system 22 may be performed such that the state of the user's eye 1 with respect to the image display mechanism 20 is another state different from the initial state. That is, the viewing state may be changed such that the view state is intentionally changed to a position where the focus is blurred or the display position of the image is shifted.
- the content is a game or the like
- an appropriate item e.g. glasses
- the degree of blur of the field of view can be adjusted according to the physical condition or awakening state of the avatar in the content. For example, it is possible to sense the state of the user and reflect it on the avatar, or to adjust the degree of blur depending on the state of the avatar in the content. For example, in a fighting game, a shooting game, etc., the view is blurred when damage or death occurs. When the right eye is turned, it is also possible to blur only the right eye. In addition, it is also possible to blur the field of view when sleepiness is strong.
- the lens system 22 or the like is moved based on eye information so that the view is realized.
- the focal length is moved so as to be close, and in the case of hyperopia, the lens system 22 or the like is moved so that the focal length is far.

- the viewing state is changed based on the viewing time of the content. For example, when the content is used beyond the specified time, it is possible to blur the view to make the user aware of tiredness and prompt a break. For example, as the set time of content (90 minutes, etc.) is approached, myopia is gradually turned on (the focal distance is reduced) to make the tired eyes feel. It can be said that this corresponds to the power mode of the television. At this time, it is also possible to determine whether or not the user is tired from biological information (brain waves, pulse, blood flow, etc.). In addition, it is also possible to display a message such as "enter tired eye mode" in the corner of the display 21. In addition, it is also possible to provide the user with content such as an image or music for healing tired eyes, for example, when there is use beyond the specified time or when it is determined that the user is tired by biological information.
- the viewing state is changed based on the state information on the state of the user. It is the processing according to the above-mentioned awakening degree, and the processing according to living body information. For example, when the mechanism etc. which monitor the physical condition of the user who wears HMD100 are provided, a display state may be changed using the monitoring result. For example, when it is determined that the user is tired from the biological information, the user is gradually brought into myopia (the focal length is reduced) to make the tired eyes feel. In addition, it is also possible to display a message such as "enter tired eye mode" in the corner of the display 21. It is also possible to provide the user with content such as images and music for healing tired eyes.
- the reliability determination unit 49 shown in FIG. 3 will be described.
- the reliability determination unit 49 determines the reliability of the detection result by the biosensor 38 based on the amount of movement (correction amount) from the initial state in the display 21 and the left and right lens systems 22. For example, as the movement amount of the lens system 22 is larger, it is determined that the HMD 100 is deviated with respect to the head. That is, it is highly probable that the detection terminal portions such as the electroencephalogram sensor and the myoelectric sensor are not sufficiently in contact with the predetermined position of the body, and the reliability of the detected signal is set low. This makes it possible to effectively use the detection result of the biological sensor 38.
- the detection terminal portion of the biological sensor 38 is in sufficient contact with the skin.
- the mechanism drive unit 45 it is determined whether the detection terminal unit is sufficiently in contact with the skin, and the reliability of the detection result is determined. It is possible.

- the information to be used may be weighted.
- the method of weighting is not limited, and may be set arbitrarily.
- each of the display 21, the lens system for left eye 22a, and the lens system for right eye 22b can be moved is described as an example.
- the present invention is not limited to this, and only the display 21 may be moved, or only the left and right lens systems 22 may be moved. Further, other members constituting the image display mechanism 20 may be movable. In addition, there may be a case where only movement of part of the image display mechanism 20 is possible as the change of the viewing state.
- the lens system 22 or the like is frequently moved by the mechanism driving unit 45, it may be determined that the tightening degree of the mounting band portion 11 is loose. If it is determined that the degree of tightening is loose, the mounting band 11 is automatically adjusted based on, for example, eye information. Alternatively, notification of urging adjustment of the mounting band portion 11 is executed.
- the present technology it is also possible to view the content in a state in which the tightening degree of the mounting band portion 11 is relaxed. For example, by executing the process shown in FIG. 9 at a high speed, it is possible to prevent the influence of the misalignment of the HMD 100 due to the loose tightening. As a result, it is not necessary to tighten the mounting band portion 11, and the mounting load on the user can be sufficiently reduced. Further, since a mechanism for finely adjusting the mounting band portion 11 is not required, simplification, downsizing and weight reduction of the apparatus are realized. Moreover, the trouble of wearing is reduced.
