Description

[Technical field]

[0001] The present invention relates to a display device, and more particularly to a configuration that opens up a user's peripheral vision. [Background technology]

[0002] Known display devices that are placed in front of a user include a head mounted display (HMD) that is worn on the user's head and a handheld display (HHD) that is held in the user's hand. These display devices often have a configuration in which the display device is placed in front of the user's eyes and covers both of the user's eyes in order to improve the immersive feeling of virtual reality (VR) or mixed reality (MR).

[0003] Covering the user's eyes improves the sense of immersion, but prevents the user from detecting dangers in the surroundings. Patent Document 1 discloses a display device that opens the user's peripheral vision while being placed in front of the user's eyes. Opening the peripheral vision reduces the sense of immersion, but increases safety (allowing the user to detect dangers in the surroundings). In addition, the continuity of the peripheral vision and the image is expected to improve mixed reality.

[0004] In order to hold the display device in front of the user's eyes, the display device may be connected to a holding member. Patent Documents 1 and 2 disclose techniques for connecting a display device to a holding member and using it as an HMD or HHD. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2019-125965 A [Patent Document 2] JP 2016-171461 A [Patent Document 3] JP 2021-114756 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the conventional techniques disclosed in Patent Documents 2 and 3 do not take into consideration the opening of peripheral vision. As a result, the peripheral vision is not opened and the user may not be able to sense surrounding danger. The conventional technique disclosed in Patent Document 1 takes into consideration the opening of peripheral vision, but does not take into consideration the connection of the display device to the holding member. As a result, when the display device is connected to the holding member, the peripheral vision is not opened and the user may not be able to sense surrounding danger. With an HHD, the user's hand may cover the peripheral vision.

[0007] The present invention aims to open up a user's peripheral vision when a display device connected to a holding member (or a display device having a part corresponding to the holding member) is placed in front of the user's eyes. [Means for solving the problem]

[0008] A first aspect of the present invention is a display device that is placed in front of a user for use, characterized in that the display device has a shape that opens up the user's peripheral vision when placed in front of the user's eyes, and has a connection portion at the top or bottom of the display device that is electrically and physically connected to a holding member that holds the display device.

[0009] A second aspect of the present invention is a display device that is placed in front of a user and used by the user, comprising a main body portion having a shape that opens up the user's peripheral vision when the display device is placed in front of the user's eyes, and a handheld portion that is held in the user's hand, the handheld portion having a shape that forms a gap between the left and right ends of the display device so as not to obstruct the user's peripheral vision in the left and right directions.

[0010] A third aspect of the present invention is a hand-held member that is held in the hand of a user with a display device that the user places in front of them for use connected to it, the hand-held member having a shape that forms a gap between the left and right ends of the display device so as not to obstruct the user's peripheral vision in the left and right directions when the display device is connected, and the display device has a shape that opens up the user's peripheral vision when the display device is placed in front of the user. Effect of the Invention

[0011] According to the present invention, it is possible to open up the user's peripheral vision when a display device connected to a holding member (or a display device having a portion corresponding to the holding member) is placed in front of the user's eyes.

[0013] (Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

[0014] FIG. 1 is a perspective view of a display device 11 according to a first embodiment. A user uses the display device 11 by placing it in front of the user's eyes. Therefore, when the user uses the display device 11, the user's eyes 13 are placed on the rear side of the display device 11. The display device 11 has a display unit 16 on the rear side. When the display device 11 is placed in front of the eyes 13, the display unit 16 projects an image onto the eyes 13. The display unit 16 includes a display panel such as a liquid crystal panel or an organic EL panel, and a prism (ocular optical system) that projects an image displayed on the display panel onto the eyes 13. The display unit 16 may be a retinal projection type display unit.

[0015] The display device 11 has, at its top, a connection portion 12 for connection to a holding member that holds the display device 11. The plane 14 is a horizontal plane on which the optical axis of the display unit 16 (eyepiece optical system) is located. 2 is provided above plane 14. Plane 14 may be interpreted as a horizontal plane on which the center of the image projected onto eye 13 is located. Furthermore, display device 11 has an imaging section 15 on the front side that captures an image of real space. Imaging section 15 is used, for example, to estimate the position and orientation of display device 11. Display unit 16 may project an image of real space captured by imaging section 15 onto eye 13. Note that display device 11 does not necessarily have to have imaging section 15.

[0016] 2 is a perspective view of a headband-shaped wearing member 21 as an example of a holding member for holding the display device 11. The user connects the display device 11 to the wearing member 21 and wears the wearing member 21 on the head. This positions the display device 11 in front of the eyes 13. The wearing member 21 has a connection section 22 with the display device 11. The wearing member 21 may have a power source or an image processing device. The wearing member 21 may have a cable for wired connection with an external device or a communication device for wireless connection with an external device.

[0017] FIG. 3 is a perspective view showing a state in which the display device 11 is connected to the mounting member 21. The connection portion 12 of the display device 11 is connected to the connection portion 22 of the mounting member 21. As a result, the display device 11 is electrically and physically connected to the mounting member 21. By connecting the display device 11 to the mounting member 21, power is supplied from the mounting member 21 to the display device 11 via the connection portions 22 and 12. For example, power is supplied to the display device 11 from a power source (internal power source) that the mounting member 21 has, or power is supplied to the display device 11 from an external device (external power source) connected to the mounting member 21 via the mounting member 21. The display device 11 is driven (performs a main operation) by the power supplied from the mounting member 21. The display device 11 may have a power source such as a small secondary battery. The electrical or physical connection between the display device 11 and the mounting member 21 may be auxiliary (additional) at a portion other than the connection portions 12 and 22.

[0018] As described above, according to the first embodiment, the connection part 12 with the mounting member 21 is provided on the upper part of the display device 11, and the display device 11 is connected to the mounting member 21 so as to be suspended from the mounting member 21. The display device 11 has a shape that opens up the peripheral vision of the user when the display device 11 is placed in front of the user's eyes 13 (a shape that does not cover the eyes 13). This makes it possible to open up the peripheral vision of the user in the left, right, and downward directions even in a state in which the display device 11 connected to the mounting member 21 is placed in front of the eyes 13 (a state in which the mounting member 21 to which the display device 11 is connected is worn on the user's head).

[0019] In addition, when dangers in the upward direction should be detected more than dangers in the downward direction, the connection part with the holding member may be provided at the bottom of the display device (for example, below the optical axis of the eyepiece optical system). This allows the user's peripheral vision to be opened in the left, right, and upward directions even when the display device connected to the holding member is placed in front of the user's eyes. In many cases, it is desirable to be able to detect dangers in the left and right directions, so the peripheral vision in the left and right directions is opened.

[0020] (Embodiment 2) Hereinafter, the second embodiment of the present invention will be described with reference to Figures 4 and 5. Note that in the following, the same points as in the first embodiment (for example, the same configuration as in the first embodiment) will not be described, and only the points different from the first embodiment will be described.

[0021] Fig. 4 is a perspective view showing a state in which the display device 11 is connected to a holding member. In Fig. 4, the holding member is a helmet-type mounting member 31. The mounting member 31 can be suitably used in situations where the safety of the user's head is important. Compared to wearing a headband-type mounting member on the head and then putting on a helmet, using the helmet-type mounting member 31 places less strain on the user.

[0022] Fig. 5 is a perspective view showing a state in which the display device 11 is connected to a holding member. In Fig. 5, the holding member is a glasses-type wearing member 41. The wearing member 41 can be suitably used in situations where portability or comfort during long-term use is important.

[0023] As described above, in the second embodiment, similarly to the first embodiment, even when the display device connected to the holding member is placed in front of the user's eyes, the user's peripheral vision can be opened in the left, right, and downward (or upward) directions. Note that the holding member is not limited to the above-mentioned one, and various holding members can be used depending on the usage method or usage environment.

[0024] (Embodiment 3) Hereinafter, a third embodiment of the present invention will be described with reference to Figures 6 to 11. In the following, a description of the same points as in the first embodiment (for example, the same configuration as in the first embodiment) will be omitted, and only points different from the first embodiment will be described.

[0025] Fig. 6 is a perspective view of a display device 11 according to the third embodiment. Fig. 7 is a perspective view of a hand-held member 51 as an example of a holding member for holding the display device 11. A user connects the display device 11 to the hand-held member 51 and holds the hand-held member 51 with his / her hand. The hand-held member 51 has a base part 53 held by the user's hand and a connection part 52 with the display device 11. The display device 11 may be interpreted as a main body part, the hand-held member 51 as a hand-held part, and the combination of the display device 11 and the hand-held member 51 as a display device.

[0026] FIG. 8 is a perspective view showing a state in which the display device 11 is connected to a hand-held member 51. A connection portion 12 provided on an upper portion of the display device 11 is connected to a connection portion 52 of the hand-held member 51. As a result, the display device 11 is electrically and physically connected to the hand-held member 51. By connecting the display device 11 to the hand-held member 51, power is supplied from the hand-held member 51 to the display device 11 via the connection portions 52 and 12. For example, power is supplied to the display device 11 from a power source (internal power source) possessed by the hand-held member 51, or power is supplied to the display device 11 from an external device (external power source) connected to the hand-held member 51 via the hand-held member 51. The display device 11 is driven (performs a main operation) by the power supplied from the hand-held member 51. The display device 11 may have a power source such as a small secondary battery. The electrical or physical connection between the display device 11 and the hand-held member 51 may be auxiliary (additional) at a portion other than the connection portions 12 and 52.

[0027] In the third embodiment, the connection part 12 with the hand-held member 51 is provided on the upper part of the display device 11, and the display device 11 is connected to the hand-held member 51 so as to be suspended from the hand-held member 51. The display device 11 has a shape that opens the peripheral vision of the user when the display device 11 is placed in front of the user's eyes 13 (a shape that does not cover the eyes 13). The hand-held member 51 has a shape that forms a gap between the left and right ends of the display device 11 so as not to block the peripheral vision of the user in the left and right directions when the display device 11 is connected to the hand-held member 51. The hand-held member 51 has a shape that opens the lower side of the display device 11 when the display device 11 is connected to the hand-held member 51. This allows the peripheral vision of the user to be opened in the left, right, and downward directions even when the display device 11 connected to the hand-held member 51 is placed in front of the user's eyes.

[0028] The gap (space) between the hand-held member 51 and the left and right ends of the display device 11 will be described with reference to Fig. 9. Fig. 9 is a cross-sectional view showing a cross section obtained by plane 14 (the horizontal plane on which the optical axis of the display unit 16 (ocular optical system) is located) in Fig. 8. In Fig. 9, eye 13 is located on the optical axis of the display unit 16.

[0029] Distance L1 is the eye distance of the user with respect to the display device 11, for example, the distance from the display unit 16 to the center of the eye 13. Distance L1 depends on the eye relief of the display unit 16. It may be the distance obtained by adding the distance (generally 10 mm) from the pupil position of eye 13 to the center of rotational motion. Distance L2 is the length of the above-mentioned gap on plane 14, and is the distance from the left end of display device 11 to the left end (inner wall) of hand-held member 51. Distance L2 is also the distance from the right end of display device 11 to the right end (inner wall) of hand-held member 51. Distance L3 is the length of hand-held member 51 in the front-to-rear direction.

[0030] Angles θ1 to θ3 are angles of the user's line of sight with respect to the optical axis of the display unit 16 (eyepiece optical system). Angle θ1 is the angle when the user views the left edge (or right edge) of the image, and is approximately half the angle of view of the image. Angle θ1 is the angle at which shading by the display device 11 begins. Angle θ2 is the angle when the user views the left edge (or right edge) of the display device 11. Angle θ2 is the angle at which shading by the display device 11 ends. Angle θ3 is the angle when the user views the left edge (or right edge) of the hand-held member 51. Angle θ3 is the angle at which shading by the hand-held member 51 begins.

[0031] Because angle θ3 is greater than angle θ2, the user can view the surroundings through the gap between the display device 11 and the hand-held member 51. Because the user holds the outside of the hand-held member 51, the user's hand does not block the peripheral vision.

[0032] 10 and 11 are diagrams showing comparative examples. FIG. 10 is a perspective view showing a state in which a display device 101 is connected to a hand-held member 501. FIG. 11 is a cross-sectional view showing a cross section obtained by plane 14 (a horizontal plane on which the optical axis of the display unit (eyepiece optical system) is located) in FIG. 10. FIGS. 10 and 11 are similar to FIGS. 8 and 9, but angle θ3 is smaller than angle θ2. Therefore, the user cannot see the surroundings through the gap between the display device 101 and the hand-held member 501.

[0033] As described above, in the third embodiment as well, when the display device connected to the holding member is placed in front of the user's eyes, the user's peripheral vision can be opened up in the left, right, and downward directions.

[0034] The hand-held member 51 may have a power source or an image processing device. The hand-held member 51 may have a cable for wired connection with an external device, or may have a communication device for wireless connection with an external device. When the hand-held member 51 has a cable, it is preferable that the hand-held member 51 has a shape that guides the cable. The hand-held member 51 may have a cable that functions as a connection part 52.

[0035] It is preferable that the distance L3 is 50 mm or more so that the width from the second finger to the fifth finger of the user falls within the distance L3, which is the length in the front-rear direction of the hand-held member 51. This can prevent the user's fingers (e.g., the fifth finger) from entering the peripheral visual field.

[0036] Considering the effective visual field of the human eye, it is preferable that the angle θ3 at which blocking by the hand-held member 51 starts is 30 degrees or more. In other words, it is preferable that the visual field in the left-right direction blocked by the hand-held member 51 is in a range of 30 degrees or more with respect to the optical axis of the eyepiece optical system.

[0037] The hand-held member 51 is connected to the display device 11 so as to enclose the display device 11, and it is preferable that the display device 11 does not protrude from the hand-held member 51 in six directions, i.e., up, down, front, back, left and right. In other words, it is preferable that the display device 11 fits within a space in which the hand-held member 51 is inscribed when the display device 11 is connected to the hand-held member 51. This allows the hand-held member 51 to hit the floor before the display device 11 when the display device 11 connected to the hand-held member 51 is dropped or placed on the floor, so that the display device 11 can be protected. The entire hand-held member 51 may protrude from the display device 11, but the hand-held member 51 may have a partial convex portion so that a part of the hand-held member 51 protrudes from the display device 11.

[0038] It is preferable that the difference (θ2-θ1) between the angle θ1 at which shading by the display device 11 starts and the angle θ2 at which shading by the display device 11 ends is small. When an image of real space is displayed, the smaller the difference (θ2-θ1), the easier it is for the user to feel a continuous connection between the image and the peripheral vision.

[0039] (Embodiment 4) Hereinafter, the fourth embodiment of the present invention will be described with reference to Figures 12 to 15. Note that in the following, the same points as in the third embodiment (for example, the same configuration as in the third embodiment) will not be described, and only the points different from the first embodiment will be described.

[0040] 12 is a perspective view of a display device 11 according to embodiment 4. The display device 11 has, at its upper portion, a positioning portion 17 for positioning with a holding member, in addition to the connection portion 12.

[0041] FIG. 13 is a perspective view of a hand-held member 61 as an example of a holding member for holding the display device 11. The hand-held member 61 has a connection portion 52, a base portion 63, a face contact portion 64, a filter 65, a positioning portion 66, and a slip stopper 67. The hand-held member 61 (base portion 63) has a cylindrical shape, unlike the hand-held member 51 (base portion 53) of the third embodiment. The base portion 63 also has an attachment surface for the filter 65. The face contact portion 64 is provided on the back side of the base portion 63. When using the display device 11 to which the hand-held member 61 is connected, the user brings the face contact portion 64 into contact with the forehead. The filter 65 covers the front surface of the hand-held member 61, and protects the display device 11 connected to the hand-held member 61, for example. In FIG. 13, the filter 65 is separated from the base portion 63, but the filter 65 is attached to the attachment surface of the base portion 63. The positioning portion 66 is formed on the upper portion of the base portion 63 and is used for positioning with the display device 11. The anti-slip portion 67 is formed on at least a part (for example, the left and right parts) of the surface of the hand-held member 61 (base portion 63).

[0042] The positioning portions 17, 66 are provided at positions different from the connecting portions 12, 52 in order to reduce the external force required to connect the connecting portions 12 and 52. The connecting portion 12 and the connecting portion 52 are connected in the vertical direction, and the positioning portions 17, 66 have a shape that suppresses movement in directions other than the vertical direction.

[0043] Fig. 14 is a perspective view showing a state in which the display device 11 is connected to a hand-held member 61. The filter 65 is omitted in Fig. 14. Fig. 15 is a cross-sectional view showing a cross section obtained by a plane 18 (a vertical plane perpendicular to the plane 14) in Fig. 14. In Fig. 15, an eye 13 is positioned on the optical axis of the display unit 16.

[0044] Angles θ1 to θ4 are angles of the user's line of sight with respect to the optical axis of the display unit 16 (eyepiece optical system). Angle θ1 is the angle when the user views the bottom edge of the image. Angle θ1 is the angle at which shading by the display device 11 begins. Angle θ2 is the angle when the user views the bottom edge of the display device 11. Angle θ2 is the angle at which shading by the display device 11 ends. Angle θ3 is the angle when the user views the bottom edge of the front of the hand-held member 61. Angle θ3 is the angle at which shading by the hand-held member 61 begins. Angle θ4 is the angle when the user views the bottom edge of the back of the hand-held member 61. Angle θ4 is the angle at which shading by the hand-held member 61 ends.

[0045] As shown in FIG. 15, the lower portion of the base 63 is configured away from the user's eyes, the angle θ3 is smaller than the angle θ2, and the angle θ4 is approximately equal to the angle θ2. This allows the user's peripheral vision to be opened in the left, right, and downward directions even though the base 63 has a cylindrical shape. Although the first finger may intrude into the peripheral vision in the downward direction, By providing the non-slip surface 67 outside the plane 18 in the left-right direction, the user will naturally place his / her first finger on the non-slip surface 67, which can prevent the first finger from entering the peripheral vision.

[0046] As described above, in the fourth embodiment as well, when the display device connected to the holding member is placed in front of the user's eyes, the user's peripheral vision can be opened up in the left, right, and downward directions.

[0047] At least a part of the hand-held member 61 (base portion 63) may be made of a transparent material. This allows the peripheral vision to be opened even if the angle θ4 at which the shielding by the hand-held member 61 ends is greater than the angle θ2 at which the shielding by the display device 11 ends. At least a part of the hand-held member 61 (base portion 63) may be made of an elastic material. For example, the base portion 63 partially using an elastic material may be produced by two-color molding. This allows the protection performance of the display device 11 to be improved.

[0048] Since the base portion 63 has a cylindrical shape, the display device 11 may have a connection portion 12 for connecting to the hand-held member 61 at a lower portion of the display device 11.

[0049] The face contact part 64 may be provided so as to be shiftable forward and backward with respect to the hand-held member 61 (base part 63). This allows the user to use the display device 11 in a positional relationship that is more suited to the user, improving convenience. The hand-held member 61 does not have to have the face contact part 64.

[0050] The anti-slip material 67 may be provided by any method. For example, a sheet-like anti-slip material 67 may be attached to the base portion 63 with double-sided tape, or may not be attached in this manner. By providing the anti-slip material 67, the stability of holding the hand-held member 61 (the hand-held member 61 to which the display device 11 is connected) can be improved. Note that the hand-held member 61 does not have to have the anti-slip material 67.

[0051] The filter 65 may be provided in any manner. For example, the filter 65 may be attached to the front surface of the base portion 63 with double-sided tape. The filter 65 may be embedded in the base portion 63. In that case, the base portion 63 may not have a surface to which the filter 65 is attached. The filter 65 may be a neutral density filter. This can improve the visibility of the image captured by the imaging unit 15 in a bright environment. The hand-held member 61 may not have the filter 65.

[0052] As long as the user's peripheral vision is not obstructed, the hand-held member 61 may have a configuration for reducing the external force required to connect the connection part 12 and the connection part 52. For example, the display device 11 and the hand-held member 61 may each be provided with two magnets that attract each other when the connection part 12 and the connection part 52 are connected.
