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 head-mounted displays (HMDs) worn on the user's head and handheld displays (HHDs) held in the user's hands. These display devices often have a configuration that covers both of the user's eyes when placed in front of the user 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 around them. Patent Document 1 discloses a display device that opens the user's peripheral vision while positioned directly in front of the user. Opening the peripheral vision reduces the sense of immersion, but increases safety (allowing the user to detect dangers around them). In addition, the continuity between the peripheral vision and the image is expected to improve mixed reality.

[0004] The display device may be connected to a holding member so as to be held in front of the user's eyes. 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] Japanese Patent Application Publication No. 2019-125965 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-171461 [Patent Document 3] Patent Publication No. 2021-114756 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the conventional technologies disclosed in Patent Documents 2 and 3 do not take into consideration the opening of peripheral vision. As a result, peripheral vision is not opened and the user may not be able to detect danger in the surroundings. The conventional technology 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, peripheral vision is not opened and the user may not be able to detect danger in the surroundings. With HHD, the user's peripheral vision may be covered by their hands.

[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 and used, characterized in that the display device has a shape that opens up the user's peripheral vision when placed in front of the user, and has a connection part 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 itself and the left and right edges 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 handheld member that is held in the hand of a user when a display device that the user places in front of them is connected to the handheld member, the handheld 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 having a shape that opens up the user's peripheral vision when the display device is placed in front of the user. [Effects of the Invention]

[0011] According to the present invention, the user's peripheral vision can be opened up 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. [Brief explanation of the drawings]

[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 display unit.

[0015] The display device 11 has, at its top, a connection part 12 for connecting 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 (ocular 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 unit 15 on the front side that captures an image of real space. Imaging unit 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 unit 15 onto eye 13. Note that display device 11 does not necessarily have to have imaging unit 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 unit 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 may have 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. This electrically and physically connects the display device 11 to the mounting member 21. By connecting the display device 11 to the mounting member 21, power is supplied to the display device 11 from the mounting member 21 via the connection portions 22 and 12. For example, power may be supplied to the display device 11 from a power source (internal power source) included in the mounting member 21, or power may be 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 its 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. A supplementary (additional) electrical or physical connection between the display device 11 and the mounting member 21 may be made at a location other than the connection portions 12 and 22.

[0018] As described above, according to the first embodiment, the connection portion 12 with the wearing member 21 is provided on the upper part of the display device 11, and the display device 11 is connected to the wearing member 21 so as to be suspended from the wearing member 21. The display device 11 has a shape that opens up the user's peripheral vision 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 allows the user's peripheral vision to be opened in the left, right, and downward directions even when the display device 11 connected to the wearing member 21 is placed in front of the eyes 13 (when the wearing member 21 to which the display device 11 is connected is worn on the user's head).

[0019] In addition, if it is more important to detect dangers in the upward direction than dangers in the downward direction, the connection portion 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 open to 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 open.

[0020] (Embodiment 2) Hereinafter, a second embodiment of the present invention will be described with reference to Figures 4 and 5. Note that, 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.

[0021] Fig. 4 is a perspective view showing the display device 11 connected to a holding member. In Fig. 4, the holding member is a helmet-type wearing member 31. The wearing member 31 can be suitably used in situations where the safety of the user's head is important. Compared to wearing a headband-type wearing member on the head and then putting on a helmet, using the helmet-type wearing 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, 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. Note that, 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 a third embodiment. Fig. 7 is a perspective view of a handheld member 51 as an example of a holding member for holding the display device 11. A user connects the display device 11 to the handheld member 51 and holds the handheld member 51 with their hand. The handheld member 51 has a base portion 53 held by the user's hand and a connection portion 52 for connecting to the display device 11. The display device 11 may be interpreted as a main body portion, the handheld member 51 as a handheld portion, and the combination of the display device 11 and the handheld 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 the upper portion of the display device 11 is connected to a connection portion 52 of the hand-held member 51. This electrically and physically connects the display device 11 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 may be supplied to the display device 11 from a power source (internal power source) possessed by the hand-held member 51, or power may be 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 its 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. A supplementary (additional) electrical or physical connection between the display device 11 and the hand-held member 51 may be made at a location other than the connection portions 12 and 52.

[0027] In the third embodiment, a connection portion 12 for connecting to a hand-held member 51 is provided on the upper portion 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 up the user's peripheral vision 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 gaps between the left and right ends of the display device 11 so as not to obstruct the user's peripheral vision in the left and right directions when the display device 11 is connected to the hand-held member 51. The hand-held member 51 also has a shape that opens up the bottom side of the display device 11 when the display device 11 is connected to the hand-held member 51. This allows the user's peripheral vision to be open 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, the eye 13 is located on the optical axis of the display unit 16.

[0029] The 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. The distance L1 is determined by the eye relief of the display unit 16. It may be the distance obtained by adding the distance (typically 10 mm) from the pupil position of eye 13 to the center of rotational movement. Distance L2 is the length of the gap on plane 14, and is the distance from the left edge of display device 11 to the left edge (inner wall) of handheld member 51. Distance L2 is also the distance from the right edge of display device 11 to the right edge (inner wall) of handheld member 51. Distance L3 is the length of handheld member 51 in the front-to-rear direction.

[0030] Angles θ1 to θ3 are angles of the user's line of sight relative to the optical axis of the display unit 16 (ocular 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 larger than angle θ2, the user can see the surroundings through the gap between display device 11 and handheld member 51. Because the user holds the outside of handheld member 51, the user's hands do 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 the display device 101 is connected to the handheld member 501. FIG. 11 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 (ocular 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 handheld 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, the user's peripheral vision can be opened up in the left, right, and downward directions.

[0034] The handheld member 51 may have a power source or an image processing device. The handheld 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. If the handheld member 51 has a cable, it is preferable that the handheld member 51 has a shape that guides the cable. The handheld member 51 may have a cable that functions as the connection portion 52.

[0035] It is preferable that the distance L3 be 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 (for example, the fifth finger) from entering the peripheral visual field.

[0036] Considering the effective field of view of the human eye, it is preferable that the angle θ3 at which blocking by the hand-held member 51 begins is 30 degrees or more. In other words, it is preferable that the horizontal field of view blocked by the hand-held member 51 be 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 the space inscribed by the hand-held member 51 when the display device 11 is connected to the hand-held member 51. This ensures that when the display device 11 connected to the hand-held member 51 is dropped or placed on the floor, the hand-held member 51 hits the floor before the display device 11, thereby protecting the display device 11. The entire hand-held member 51 may protrude from the display device 11, or 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 begins 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 more easily the user will perceive a continuous connection between the image and his or her peripheral vision.

[0039] (Embodiment 4) Hereinafter, a fourth embodiment of the present invention will be described with reference to Figures 12 to 15. Note that, in the following, a description of the same points as in the third embodiment (for example, the same configuration as in the third embodiment) will be omitted, and only 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 top, a positioning portion 17, separate from the connection portion 12, for positioning with the holding member.

[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 non-slip surface 67. Unlike the hand-held member 51 (base portion 53) of the third embodiment, the hand-held member 61 (base portion 63) has a cylindrical shape. The base portion 63 also has an attachment surface for the filter 65. The face contact portion 64 is provided on the rear side of the base portion 63. When using the display device 11 connected to the hand-held member 61, the user contacts the face contact portion 64 with their forehead. The filter 65 covers the front of the hand-held member 61 and protects, for example, the display device 11 connected to the hand-held member 61. Although the filter 65 is separated from the base portion 63 in FIG. 13, 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 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 direction between the connecting portions 12 and 52 is 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 handheld member 61. The filter 65 is omitted in Fig. 14. Fig. 15 is a cross-sectional view showing a cross section obtained by plane 18 (a vertical plane perpendicular to plane 14) in Fig. 14. In Fig. 15, the 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 relative to the optical axis of the display unit 16 (ocular 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 their 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, 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 shielding by the hand-held member 61 ends is greater than the angle θ2 at which shielding by the display device 11 ends. Also, 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 may be produced by two-color molding, with a portion of the elastic material being used. 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 handheld member 61 at the bottom of the display device 11.

[0049] The face-contacting portion 64 may be provided so as to be shiftable forward and backward relative to the hand-held member 61 (base portion 63). This allows the display device 11 to be used in a position that is more suited to the user, improving convenience. Note that the hand-held member 61 does not necessarily have to have the face-contacting portion 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 it may not be attached in this way. By providing the anti-slip material 67, it is possible to improve the stability of holding the hand-held member 61 (the hand-held member 61 to which the display device 11 is connected). Note that the hand-held member 61 does not have to have the anti-slip material 67.

[0051] The filter 65 may be provided by any method. 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 does not need to have a surface on 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 does not need to have the filter 65.

[0052] To the extent that it does not interfere with the user's peripheral vision, handheld member 61 may have a configuration for reducing the external force required to connect connecting portion 12 and connecting portion 52. For example, display device 11 and handheld member 61 may each be provided with two magnets that attract each other when connecting connecting portion 12 and connecting portion 52.
