Description

  The present invention relates to a display device such as an HMD (head mounted display).

  Conventionally, in a display device such as an HMD (head-mounted display), there is a method (hereinafter referred to as a laser scanning method) in which laser light is two-dimensionally scanned and directly drawn on the retina of the eye. (For example, refer to Patent Document 1). Laser scanning display devices include a retinal scanning display, a retinal irradiation display, a direct retina display, a laser scanning display, a direct-view display device, an RSD (Retina Scanning Display), and a VRD (Virtual Retina Display). ), Etc.

  FIG. 1 shows an example of the structure of a glasses-type HMD. In FIG. 1, light source 101, 110 for emitting laser light, wavefront shape changing means 102, 109 for controlling the wavefront of the laser light, and scanning means 103, 108 for scanning the laser light in a two-dimensional direction are mounted on the spectacle frame. Yes. The laser light is projected toward the spectacle lens by the scanning means, reflected by the deflecting means 104 and 107 provided on the surface of the spectacle lens, is incident on the user's eye, and forms an image on the retina. Here, a half mirror, a hologram optical element (HOE), or the like is used for the deflecting means 104 and 107, and the user can view both the outside scenery and the image drawn by the laser at the same time. . For the scanning means 103 and 108, a mirror device that scans laser light in a two-dimensional direction by vibrating a single single-plate mirror in a uniaxial or biaxial direction is used.

  In addition, a conventional micro display type HMD uses a configuration in which a micro display such as a liquid crystal display or an organic EL display is used as a light source instead of a laser light source, and light from the micro display is guided to a user's eyes by a deflecting unit. ing. Further, as shown in FIG. 1, an HMD provided with display portions in the left and right eyes is hereinafter referred to as a binocular HMD.

  Normally, when a video is displayed on the left and right eyes with a binocular HMD, a fusion effect works between the images captured by humans with the left and right eyes. The fusion effect is a phenomenon in which videos viewed by the user with the left and right eyes are combined into one and recognized by the user. FIG. 3 shows an example of the fusion effect. 301 is an image displayed for the user's left eye, and 302 is an image displayed for the user's right eye. When such an image is presented to the left and right eyes, the human brain combines and recognizes the left and right images, so the user displays an image 303 in which the images 301 and 302 are combined. Is recognized as an image.

  When a defect occurs in the visual field of the user's right eye due to a disease such as glaucoma or age-related macular degeneration, the image captured by the user's right eye is originally a part of the screen lacking as shown in 302. Become. However, due to the above-described fusion effect of both eyes, even if there is a portion that is not visible with the right eye, if the left eye is normal, the human brain will recognize the image 303 without a defect. This has the effect of compensating for abnormalities in the visual field, but prevents early detection of visual field abnormalities.

Conventionally, in order to find such a visual field defect, a visual field inspection device or the like is used (see, for example, Patent Document 2).
JP 10-301055 A JP 2003-000542 A

  When the same image is displayed on the left and right eyes by the binocular HMD, even if the user has an abnormality in the visual field of one eye, the user does not notice a defect in his visual field due to the fusion effect of both eyes. The problem that disease progresses arises.

  In addition, inspection of visual field abnormalities with a conventional visual field inspection device is performed with the line of sight fixed at the center of the visual field, which forces the user to fix the eyeball, which places a heavy burden on the user and is not routinely used. Have difficulty.

  The present invention solves the above-mentioned problems. By providing the eyeglass-type HMD used by the user on a daily basis with a function of inspecting eye health, the burden on the user in visual field inspection is reduced, and medical conditions such as visual field defects are reduced. The purpose is to promote awareness.

  In order to solve the above-described conventional problems, an image display device according to the present invention is a device that displays an image on both eyes of a user, and provides inspection information for inspecting eye abnormalities in either of the left and right eyes of the user. Inspection information display means for displaying the reaction information, reaction detection means for detecting a reaction of the user to the inspection information, reaction history management means for managing the detection result of the reaction detection means as a reaction history, and the reaction history management means It comprises inspection method control means for determining at least one of display contents, display size, display time, and display position of the inspection information displayed to the user from the reaction history managed by.

  With this configuration, it is possible to detect a user's visual field loss early without being affected by the fusion effect of both eyes.

  In addition, the reaction history held by the reaction history management means of the present invention includes information on the display position, display content, display size, display time, and presence / absence of the user's reaction to the display information of the inspection information displayed to the user, When displaying test information at a display position where there has been no user response in the reaction history, the method control means includes at least a display size and a display time of the test information displayed at the display position in the past from the reaction history. One is acquired, and at least one of the display size and the display time of examination information to be newly displayed is made larger than the display size and the display time of past examination information.

  With this configuration, it is possible to gradually increase the display of information for a place where the user has not reacted, and to measure the degree of visual field loss of the user.

  In addition, the reaction history held by the reaction history management means of the present invention includes information on the display position, display content, display size, display time, and presence / absence of the user's reaction to the display information of the inspection information displayed to the user, When displaying the test information at a display position where the user's reaction has occurred in the reaction history, the method control means is configured to display a display size and a display time of the test information displayed at the display position in the past from the reaction history. At least one of them is acquired, and at least one of the display size and display time of examination information to be newly displayed is made smaller than the display size and display time of past examination information.

  With this configuration, it is possible to gradually reduce the display of information for a place where the user has reacted, and to determine in more detail the loss of the user's visual field.

  In addition, the inspection method control means of the present invention, when there is a non-reactive portion in which the user did not show a reaction in the reaction history held by the reaction history management means, when the inspection information is newly displayed, there is no reaction The vicinity of the place is determined as the display position.

  With this configuration, it is possible to focus on the visual field at a place where there is a suspicion of visual field loss.

The display position is determined at a location that is a certain distance from the position.

  With this configuration, it is possible to inspect the visual field defect in the peripheral visual field portion without prompting the user to move the line of sight.

  The image display apparatus according to the present invention further includes a line-of-sight detection unit that detects a user's line of sight, and the reaction detection unit responds to the examination information from the movement of the user's line-of-sight position detected by the line-of-sight detection unit. It is characterized by determining whether or not.

  With this configuration, it is possible to automatically obtain a response to inspection information.

  By providing the eyeglass-type HMD used by the user with a function of inspecting eye abnormalities, it becomes possible to promote awareness of medical conditions such as visual field defects.

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

(Embodiment 1)
FIG. 1 shows a configuration diagram (a plan view and a side view) of a glasses-type HMD (head-mounted display) in Embodiment 1 of the present invention. FIG. 2 is a detailed view of a part of FIG.

  In the configuration diagrams of FIGS. 1 and 2, each component and its relationship are described.

  The light sources 101 and 110 output beams. As shown in FIG. 2, the beam to be output is a laser beam obtained by combining the laser beams output from the red laser light source 211, the blue laser light source 212, the green laser light source 213, and the infrared laser light source 215, and from each color laser light source. By appropriately modulating the output of, laser light of any color can be output. Furthermore, an image can be displayed on the retina of the user's eye by performing modulation in conjunction with wavefront shape changing means and scanning means described later.

  In FIG. 2, 211 is a red semiconductor laser light source, 212 is a blue semiconductor laser light source, 213 is an infrared semiconductor laser light source, and SHG (Second Harmonic Generation: Second Harmonic Generation) that converts infrared light into green. ) It is shown as a combination of elements. Reference numeral 215 uses an infrared semiconductor laser distributed in the middle of 213 for generating the green laser. By using this configuration, the same semiconductor laser light source can be used to generate the infrared laser and the green laser, so that the number of parts and the cost can be reduced. Note that 213 may be a green semiconductor laser light source, and in that case, 215 may hold its own semiconductor laser light source. Each light source may be a solid laser, a liquid laser, a gas laser, or a light emitting diode.

  In FIG. 2, the laser light is modulated by each laser light source, but the means for modulating the light output from the laser light source may be used in combination with the laser light source to modulate the laser light.

  The light sources 101 and 110 include the light detection means 214 in FIG. The light detection means detects a beam spot diameter on the retina of the user by detecting reflected light from the retina of the user's eye.

  The light detection means 214 may be an image sensor such as a CCD camera. In this case, a retinal image may be generated by reflected light from the retina, and the beam spot diameter may be detected from the size of the beam spot reflected there.

  The wavefront shape changing means 102 and 109 change the wavefront shapes of the beams from the light sources 101 and 110, respectively, so that the spot sizes of the beams deflected by the deflecting means 104 and 107 described later are within a predetermined range. To do. Hereinafter, the “spot size” of the beam is treated as the spot size on the retina of the user's eye.

  The “wavefront shape” is a three-dimensional shape of a beam wavefront, and includes flat, spherical, and aspherical shapes.

  In FIG. 2, the focal length horizontal component changing means 201 and the focal length vertical component changing means 202 are arranged in series in the optical path, so that the horizontal curvature and the vertical curvature of the wavefront shape are independent. Can be changed. The focal length horizontal component changing unit 201 changes the curvature in the horizontal direction by changing the distance between the cylindrical lens and the mirror. The focal length vertical component changing unit 202 changes the curvature in the vertical direction by using a cylindrical lens arranged perpendicular to the cylindrical lens of the focal length horizontal component changing unit 201. In addition, both the focal length horizontal component changing unit 201 and the focal length vertical component changing unit 202 change the beam diameter along with the change in curvature.

  In addition, if the curvature in the horizontal direction is changed more greatly than in the vertical direction, the change in the horizontal direction can be handled more greatly. Therefore, when the horizontal viewing angle of the screen is desired to be larger than the vertical viewing angle, the scanning means ( This is particularly effective when the horizontal incident angle of the beam from the scanning means to the deflecting means (described later) is larger than the vertical incident angle, as in an HMD that will be described later.

  In FIG. 2, among the items representing the wavefront shape, only a part of the wavefront shape, that is, the curvature in the horizontal direction, the curvature in the vertical direction, and the diameter of each is changed. There may be means for changing the distribution of the wavefront, the shape and size of the wavefront end, and the like.

  The wavefront shape changing means in FIG. 2 changes the wavefront shape using a cylindrical lens and a mirror, but as other means, a liquid crystal lens, a variable shape lens such as a liquid lens, a diffraction element, an EO element ( An electro-optical conversion element) or the like may be used.

  Scanning means 103 and 108 two-dimensionally scan the beams from the wavefront shape changing means 102 and 109, respectively. The scanning means is a single-plate small mirror that can change the angle two-dimensionally, and is a MEMS (Micro-Electro-Mechanical-System) micromirror.

  The scanning unit may be realized by a combination of two or more types of scanning units, such as for horizontal scanning and vertical scanning.

  The deflecting units 104 and 107 change the directions of the beams scanned by the scanning units 103 and 108, respectively, toward the user's eyes. In the deflecting means 104 and 107, for example, a photopolymer layer is formed on the inner side (eye side) of the spectacle lens, a Lippmann volume hologram is formed on the photopolymer layer, and the beam from the scanning means is transmitted to the user's eye. It is made to be diffracted and focused on the pupil. The photopolymer layer may be formed with multiple holograms reflecting red, green, and blue light from each light source, or three layers of holograms corresponding to each color light may be laminated. Good. In addition, by using the wavelength selectivity of the hologram, only light of the light source wavelength is diffracted, and light of wavelengths other than the light source wavelength that occupies most of the light from the outside world is not affected by diffraction, It can be a transmissive display. Further, the reflection performance of the deflecting means may be made different between the visible light beam and the infrared beam by utilizing the wavelength selectivity of the hologram. Viewing images by creating holograms so that visible light is incident on the user's pupil and focused on the retina, and holograms are created so that infrared rays are irradiated on the upper and lower eyelids instead of the pupil. It is possible to stimulate the meibomian glands with infrared rays.

  The deflection means is not limited to deflection by a diffraction element such as a hologram, and may be a mirror such as a concave mirror or a lens such as a convex lens. The deflecting means also includes a method of changing a part of the diverging light from the screen toward the user's eyes as a result of the beam hitting the screen and diverging, such as a reflective screen or a transmissive screen.

  The control means 105 and 111 include an integrated circuit that controls each part of the HMD. The outputs of the lasers and the operations of the wavefront shape changing means and the scanning means are performed by the control means 105 and 111.

  FIG. 5 shows a functional block diagram of the control means 105 in the present embodiment. The function blocks 501 to 505 in FIG. 5 will be described later.

  The control unit may include a communication unit that wirelessly connects to a peripheral device such as a mobile phone and receives a video / audio signal. The image control unit 1804 may include a memory that stores an image to be presented to the user, or may acquire an image to be presented to the user from an external device by wireless.

  The control means 105 and 111 may be one, and the control means 105 or 111 may control the operations of the laser light source, the wavefront shape changing means, the scanning means, and the headphones corresponding to the left and right eyes.

  The headphone units 106 and 112 include speakers and output sound.

  The headphone unit may include a battery that supplies power to each unit of the HMD.

  In addition, each means and each part in FIG. 1 may be incorporated in one HMD, or may not be incorporated. For example, all the components in FIG. 1 may be included in one HMD, or the headphone unit may not be provided. Moreover, each part may be distributed. For example, the control means may be partly included in the scanning means and the wavefront shape means. 1 may be shared by a plurality of devices. For example, the laser light source may be shared by two HMDs.

  In the following, an example of processing for inspecting a user's visual acuity and visual field abnormality by displaying inspection information in the beam scanning display apparatus of FIG. 1 will be described.

  FIG. 4 shows an example of display of inspection information in the present embodiment. 401 is an image displayed on the left eye portion of the HMD in FIG. 1, and 402 is an image displayed on the right eye portion of the HMD. In this example, the examination information 403 is displayed only for the right eye. When such a display is made, there is a possibility that there is an abnormality in the visual field of the right eye on which the examination information 403 is displayed when the user does not show any response to the examination information 403. The image display device of the present invention accumulates the user's reaction history for the examination information 403 while changing the display position, display size, and display time of the examination information 403, and does not react to the examination information 403 in the visual field of the left and right eyes of the user. Determine if there is a part. In the example of FIG. 4, the examination information is displayed on the right eye, but the examination information may be displayed on either the left or right eye.

  In the present embodiment, the visual field abnormality inspection based on the inspection information is performed by executing steps 601 to 606 shown in FIG.

(Step 601 Determination of display position)
In this step, the inspection method control unit 502 determines the position where the inspection information is displayed. In the present embodiment, the inspection method control unit 502 executes the processing of steps 701 to 704 shown in FIG. 7 in this step of determining the display position X of the inspection information.

(Step 701: Determination of unreacted location)
First, the inspection method control unit 502 acquires a reaction history indicating how the past user has reacted to the inspection information from the reaction history management unit 501. FIG. 8 shows an example of the reaction history in the present embodiment. In this example, information regarding which examination information is displayed on the left and right eyes, the contents of the displayed examination information, the display position, the display time, and the presence or absence of a user's reaction to the examination information are recorded as a reaction history. . In the present embodiment, a display position where the user has not shown a reaction when the examination information has been displayed in the past is referred to as a non-reaction place, and a display position where the user has shown a reaction is referred to as a reaction place.

  The inspection method control unit 502 inspects whether or not there is a non-reactive portion from the acquired reaction history. If there is an unreacted location, the inspection method control unit 502 executes the process of step 702. If there is no unreacted part, the inspection method control unit 502 executes the process of step 703.

(Step 702: Judgment of the elapsed time from the previous display at the no-reaction point)
The inspection method control unit 502 acquires the display time A of the display most recently performed among the non-reaction points existing in the reaction history acquired from the reaction history management unit 501. At this time, when the predetermined time B has elapsed from the display time A as the current time, the inspection method control unit 502 performs the process of step 704. If the current time has not passed the display time A for a certain time B, the process of step 703 is performed.

  As the value of the fixed time B, a value recorded in advance on a recording medium in the inspection method control unit 502 may be used, or a value input by a user using the HMD using an input interface may be used. good.

(Step 703 Determination of new display position)
The inspection method control unit 502 acquires information related to the position where the information has been displayed in the past from the reaction history acquired from the reaction history management unit 501, and displays the position where the information has not been displayed in the past as the display position X of the inspection information. Determine as.

  When determining the display position X, first, it is determined at random which of the left and right eyes is displayed, then the coordinates of the display position are randomly generated, and the one that does not match the past display position is selected. Alternatively, an intermediate position between display positions displayed in the past may be determined as the display position X. Further, when there is a non-reacted location in the reaction history, a point near the non-reacted location may be determined as the display position X. At this time, the distance from the unreacted portion may be determined randomly, or a fixed value stored in the recording medium in the inspection method control means 502 may be used.

  Alternatively, the user's current line-of-sight position may be detected from the output result of the light detection means 214, and a place that deviates from the user's line-of-sight position by a certain value may be determined as the display position X. At this time, the distance from the user's line-of-sight position may be determined randomly, or a fixed value stored in the recording medium in the inspection method control means 502 may be used. A value input by the user via the input interface may be used.

  If inspection information is already displayed at all display positions, the display position displayed at the oldest time may be selected as the display position X. May be used as the display position X. Further, the position displayed most recently in the reaction history may be used as the display position X.

(Step 704 Redisplay to unreacted location)
The inspection method control unit 502 determines, as the display position X, the display position of the display most recently performed among the non-reaction points where the user did not respond from the reaction history acquired from the reaction history management unit 501. To do.

  When the inspection method control unit 502 determines the display position X by executing Steps 701 to 704, the inspection method control unit 502 performs the process of Step 602.

(Step 602 Determination of inspection information)
In this step, the inspection method control means 502 determines inspection information Y to be displayed. The inspection method control unit 502 acquires a list of inspection information that can be displayed to the user from the inspection information management unit 503. FIG. 9 shows an example of an inspection information list held by the inspection information management means 503 in the present embodiment. In this example, information on the name, the time required for display, the size of information, and the visibility is shown for each inspection information. Here, the visibility is an index indicating the visibility of the information, and a larger value is given to information that is easy for the user to see such as bright colors. The visibility of each piece of inspection information may be created in advance by the creator of the information as metadata, or may be calculated automatically by the inspection information management means 503 from the information content, size, and color information. good. Further, the user may input the visibility of each piece of inspection information from the input interface.

  The inspection method control unit 502 selects the inspection information Y to be displayed to the user from the list acquired from the inspection information management unit 503. The inspection information may be selected at random from the list. In addition, when the display position X determined in step 601 is a non-reactive portion where the user has not reacted in the past, a method of selecting information having the highest visibility as the inspection information Y may be used.

  When the inspection method control unit 502 determines the inspection information Y, the inspection method control unit 502 executes Step 603.

(Step 603 Determination of display method)
In this step, the inspection method control unit 502 determines a display method for displaying the inspection information Y selected in the previous step 602 at the display position X determined in the step 601. In the present embodiment, the inspection method control unit 502 determines the display size α and the display time β of the inspection information Y.

  When displaying in an unreacted location.

  When the display position X is a non-reaction location, the inspection method control unit 502 determines whether or not the inspection information Y has been displayed for the display position X in the past from the reaction history held by the reaction history management unit 501. Determine. When there is a history in which the inspection information Y is displayed for the display position X in the reaction history, the inspection method control unit 502 displays the display size α0 when the inspection information Y is displayed at the display position X from the reaction history and The display time β0 is acquired. When there are a plurality of histories in which the examination information Y is displayed at the display position X in the reaction history, information on the display size α0 and the display time β0 of the examination information displayed most recently is acquired.

  After obtaining the values of α0 and β0, the inspection method control means 502 determines the display size α of the inspection information Y as α1 times α0 and the display time β as β1 times β0. Here, α1 and β1 are values larger than 1, and in order to determine whether or not the user's visual field is missing, information larger than the previous time is displayed for a long time at a location where the previous user did not react. .

  As the values of α1 and β1, values recorded in advance on a recording medium in the inspection method control unit 502 may be used, or values input by the user using the HMD using the input interface may be used. good.

  When the inspection information Y has not been displayed for the display position X in the past, the inspection method control unit 502 sets the display size and the display time of the inspection information Y held by the inspection information management unit 503 as the display size α. And used as the display time β.

  When displayed at the reaction site.

  When the display position X is a reaction location, the inspection method control unit 502 determines whether or not the inspection information Y has been displayed at the display position X in the past from the reaction history held by the reaction history management unit 501. . When there is a history in which the examination information Y is displayed at the display position X in the reaction history, the examination method control unit 502 displays the display size α0 and the display time when the examination information Y is displayed at the display position X from the reaction history. Obtain β0. When there are a plurality of histories in which the examination information Y is displayed for the display position X in the reaction history, information on the display size α0 and the display time β0 of the examination information displayed most recently is acquired.

  After obtaining the values of α0 and β0, the inspection method control means 502 determines that the display size α of the inspection information Y is α2 times α0 and the display time β is β2 times β0. Here, α2 and β2 are values smaller than 1, and in order to determine whether or not the user's visual field is missing, information smaller than the previous time is displayed for a short time at the location where the previous user reacted.

  As the values of α2 and β2, values recorded in advance on the recording medium in the inspection method control unit 502 may be used, or values input by the user using the HMD using the input interface may be used. good.

  When the inspection information Y has not been displayed for the display position X in the past, the inspection method control unit 502 sets the display size and the display time of the inspection information Y held by the inspection information management unit 503 as the display size α. And used as the display time β.

  ・ When there is no reaction history corresponding to the display position X.

  If no inspection information has been displayed for the display position X in the past, the inspection method control unit 502 displays the display size and display time of the inspection information Y held by the inspection information management unit 503 as the display size α. And used as the display time β.

  Note that the inspection method control unit 502 may use a method of displaying the inspection information with a constant display size and display time regardless of the display size and display time of the inspection information held by the inspection information management unit 503. As the display size and display time at this time, values recorded in advance on the recording medium in the inspection method control unit 502 may be used, or values input by the user using the HMD using the input interface may be used. May be.

  When the display position X, the inspection information Y, the display size α, and the display time β are determined in steps 601 to 603, the inspection method control unit 502 notifies the inspection information display unit 504 of the information.

(Step 604 Display of inspection information)
In this step, control is performed so that the inspection information display unit 504 displays the inspection information Y determined by the inspection method control unit 502 in the above-described 601 to 603 with respect to the display position X with the display size α during the display period β. Do. In the present embodiment, the examination information display means 504 controls the light sources 101 and 110, the wavefront shape changing means 102 and 109, and the scanning means 103 and 108 in the HMD in FIG. Inspection information is displayed on either one.

  When the inspection information display unit 504 displays the inspection information, the reaction detection unit 505 next executes step 605.

(Step 605 Detection of reaction to inspection information)
In this step, the reaction detection unit 505 detects the user's reaction to the examination information Y displayed in the previous step 604.

  In the present embodiment, the reaction detection unit 505 measures the movement of the user's line of sight from the information of the light detection unit 214 and determines whether or not the user has turned his / her line of sight to the examination information Y.

  The reaction detection unit 505 may determine that there is a reaction when the user inputs the inspection information Y using an input interface connected to the HMD.

  When detecting the user's reaction to the examination information Y, the reaction detection unit 505 notifies the reaction history management unit 501 of the information.

(Step 606 Reaction history update)
In this step, the reaction history management unit 501 updates the reaction history according to the reaction result of the user notified from the reaction detection unit 505 in the previous step 605. In the present embodiment, the display result of the examination information performed this time is added to the reaction history table shown in FIG.

  By repeating the above steps 601 to 605, it is possible to display information for inspecting visual field abnormality in either of the user's left and right eyes, and to accumulate the user's reaction history for the display position of the inspection information. . If the user does not respond to a specific display position, there is a possibility that the visual field of that part may be lost, so the HMD displays a message warning the user of abnormal visual field. By performing this processing, it is possible to detect an abnormality in the visual field that is usually difficult to notice at an early stage.

  Note that the examination information display means 504 may display only the examination information Y, or display TV images or images from external devices connected to the HMD for the left and right eyes of the user, and display these images. You may display the test | inspection image Y so that it may overlap on. In the example of FIG. 4, the inspection information Y is an example of being superimposed on the video.
