Description

[Technical Field]

[0001] The present invention relates to a pad and a head-mounted device, and more particularly to a mounting mechanism of the head-mounted device. [Background technology]

[0002] Head-mounted displays (HMDs) are well known as devices worn on the head. HMDs are widely used due to their advantages, such as the ability to easily view images on a large screen, ease of stereoscopic vision, and the ability to move with the user.

[0003] Known HMD wearing mechanisms include one that secures the HMD to the head by tightening a belt-like member around the head, and another that provides pads on the front and back of the head and moves the pad on the back of the head back and forth to press the HMD against the head and secure it in place.

[0004] HMDs must be stable and comfortable to wear, regardless of the size and shape of each user's head. For example, they must be able to hold the display in a position and posture that allows for accurate viewing, and maintain the display's position even when the user moves their head.

[0005] In HMDs, the parts that come into contact with the user's head (pads) may be made of low-hardness, easily deformable materials such as various elastomers and their foams. By using such easily deformable materials, it is possible to ensure close contact between the pads and the head, regardless of the size or shape of the head.

[0006] Patent Document 1 discloses an HMD in which the entire wearing device is an integral structure using an elastomer. Patent Document 1 discloses that the wearing device is provided so as to encircle the outer periphery of the user's head, including the forehead, and that the wearing device is fixed to the user's head by tightening a part of the wearing device (a strap). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Special Publication No. 2023-518610 Summary of the Invention [Problem to be solved by the invention]

[0008] However, with the technology disclosed in Patent Document 1, the excessive tightness of the wearing device can easily cause discomfort to the user. Also, in order to fix the position and orientation of the display unit relative to the user's head and prevent it from shifting, it is necessary to apply strong pressure to the user's head, which can cause even greater discomfort to the user when used for long periods of time.

[0009] Even with the above-mentioned configuration using a pad, the user may experience discomfort. For example, if the pad has a high hardness, the pressure applied to the user's head by the pad varies greatly depending on the position on the pad, which can cause discomfort or a feeling of pressure. Furthermore, if the pad has a high hardness, the adhesion between the pad and the head deteriorates, causing the display unit to become more misaligned relative to the head. Reducing the pad's hardness improves the adhesion between the pad and the head, but weakens the reaction force from the pad to the head, making the display more likely to become misaligned.

[0010] The present invention aims to prevent the display unit from shifting when using an HMD and to reduce the feeling of pressure and discomfort. The object of the present invention is to provide a pad and a head-mounted device that can [Means for solving the problem]

[0011] The pad of the present invention is a pad that comes into contact with a part of the user's head when using a head-mounted display (HMD), and is characterized by having a first part and two second parts that sandwich the first part and fit around the head when using the HMD, and the second parts are harder than the first parts. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a head-mounted device that can suppress displacement of the display unit and reduce the feeling of pressure and discomfort when using an HMD. [Brief explanation of the drawings]

[0014] Hereinafter, embodiments of the present invention will be described. However, the configurations disclosed in the following embodiments, such as the functions, materials, shapes, and relative arrangements of parts, are merely examples of aspects related to the present invention and are not intended to limit the present invention. Furthermore, the problems solved by the configurations disclosed in the following embodiments or the actions or effects obtained from the disclosed configurations are not intended to limit the present invention.

[0015] (Embodiment 1) Hereinafter, a first embodiment will be described in detail with reference to the accompanying drawings. FIG. 1 is an external view of an HMD 100 according to the first embodiment. The HMD 100 has a display unit 1 and a mounting unit 2 (head-mounted device) that a user H wears on their head. The display unit 1 may be formed to be detachable from the mounting unit 2, or may be formed to be inseparable. In this specification, a direction along the circumference of the head of the user H when using the HMD 100 is referred to as a left-right direction. Furthermore, of the multiple directions along the head of the user H when using the HMD 100, a direction perpendicular to the direction along the circumference of the head of the user H is referred to as an up-down direction. Furthermore, a direction that is the front-to-back direction of the user H when using the HMD 100 is simply referred to as a front-to-back direction.

[0016] The display unit 1 delivers an enlarged virtual image of the display element to the eyes of the user H using a display element (not shown) and a display optical system (not shown). The display element may be, but is not limited to, an EL (Electro Luminescence) panel, an LCD, or the like. The display unit 1 may also include one or more cameras 11 that capture an image in front of the eyes (forward) of the user H. The HMD 100 may generate an image in which CG (Computer Graphics) or the like is superimposed on an image of real space (real image) acquired by the camera 11, and display the image on the display unit 1. However, the process of superimposing CG or the like on the captured real image may be performed by the display unit 1, or may be performed by an image processing device (not shown) such as a personal computer connected to the display unit 1 by a cable (not shown). The connection between the image processing device and the display unit 1 may be wireless, rather than wired via a cable.

[0017] 2 is a side view showing a state in which the user H is wearing the HMD 100. A first pad 3 and a second pad 4 are present between the inner surface of the wearing unit 2 and the user H. The first pad 3 and the second pad 4 may be part of the wearing unit 2 (head-mounted device), or may be auxiliary devices separate from the wearing unit 2. The wearing unit 2 shown in FIGS. 1 and 2 is a rigid body that surrounds the head of the user H, and is held on the head of the user H by a tensioning mechanism (not shown).

[0018] FIG. 3 is a top view of a state in which the user H is wearing the HMD 100. The state in FIG. 3 may be interpreted as a state in which the user H is viewing an image on the display unit 1. As shown in FIG. 3, the HMD 100 may have a joint unit 5 that connects the left and right ends of the wearing unit 2 and fits around the head of the user H. In this case, the entire wearing unit 2 does not need to be rigid, as long as the wearing unit 2 is rigid and has a hardness (rigidity) higher than that of the second pad 4 and does not deform (is difficult to deform). The joint unit 5 may be a band such as rubber, and may be arranged to fit around the head of the user H, thereby pressing the wearing unit 2 toward the head of the user H.

[0019] Here, the definitions of the forehead, back of the head, and temporal regions of the user H in embodiment 1 will be described. The forehead of the user H is assumed to be in a range of about 60° from the center of the forehead to each of the temples, the occipital region is assumed to be in a range from directly behind the user H to each of the user H's left and right ears (not shown), and the temporal region is assumed to be between the forehead and the occipital region.

[0020] The first pad 3 and the second pad 4 are pads that come into contact with a portion of the user H's head when the HMD 100 is in use. The first pad 3 and the second pad 4 are located along the user H's head and between the wearing unit 2 and the user H's head, supporting the wearing unit 2 and the head so that the wearing unit 2 does not move relative to the user H's head. The first pad 3 is positioned to correspond to the center of the user H's forehead, and two second pads 4 are positioned to sandwich the first pad 3 in a direction along the user H's head. The first pad 3 and the second pad 4 may be positioned apart from each other or in contact with each other. The hardness of the second pad 4 is higher than that of the first pad 3. The first pad 3 and the second pad 4 may be formed as a single, integrated pad, or may be formed as separate pads. When the first pad 3 and the two second pads 4 are formed as an integrated pad, the hardness may vary depending on the portion of the pad. The first pad 3 and the second pad 4 have a thickness that allows the attachment unit 2 to be sufficiently spaced apart from the head of the user H. This makes it possible to prevent the user H from feeling uncomfortable even if the attachment unit 2 is rigid. Furthermore, the attachment unit 2 has a structure that does not come into direct contact with the user H, or a structure that does not apply too strong a reaction force to the user H. This also makes it possible to prevent the user H from feeling uncomfortable.

[0021] The first pad 3 and the second pad 4 are arranged side by side in a direction along the circumference of the head of the user H and are provided at a position corresponding to the forehead (frontal region), but not on the temporal region. The attachment unit 2 is rigid and does not deform, and therefore, according to the attachment unit 2 of embodiment 1, even when the articulated portion 5 comes into contact with the temporal region of the user H, which would be uncomfortable if the attachment unit 2 were to be subjected to strong contact, the temporal region of the user H will not be compressed.

[0022] Here, consider a case where the hardness of the first pad 3 and the hardness of the second pad 4 are the same. In this case, the first pad 3 located mainly in the center of the forehead becomes more crushed, and the reaction force of the first pad 3 becomes the main force fixing the attachment unit 2. As a result, the attachment unit 2 is likely to rotate around the center of the forehead, and the position and posture of the attachment unit 2 relative to the head of the user H are likely to shift. In contrast, in embodiment 1, the hardness of the second pad 4 is higher than that of the first pad 3, so the reaction force at the position of the second pad 4 is higher than the reaction force at the position of the first pad 3. As a result, the reaction force of the second pad 4 becomes the main force fixing the attachment unit 2. In embodiment 1, there are two main fulcrums for holding the attachment unit 2 on the head of the user H, so the resistance to the rotational moment when the attachment unit 2 shifts so as to rotate relative to the head is large, making such shifting less likely to occur. Therefore, Therefore, the fastening force can be weakened compared to when the hardness of the first pad 3 and the hardness of the second pad 4 are the same.

[0023] The hardness of the first pad 3 and the hardness of the second pad 4 were measured. The effects were confirmed while changing the hardness difference between the first pad 3 and the second pad 4. As described above, in the first embodiment, the hardness of the second pad 4 is higher than that of the first pad 3. To measure the hardness difference, the hardness of the first pad 3 and the hardness of the second pad 4 were measured using an Asker rubber hardness tester, a Type E durometer conforming to JIS K 6253-3. From the measurement results, evaluation was not possible when the hardness difference was between 0 and 4, but was possible when the hardness difference was 5 or more. It was found that when the hardness difference was between 10 and 25, the user H could wear the attachment unit 2 comfortably. It was found that when the hardness difference was approximately 35 or more, the attachment unit 2 was not supported by the first pad 3 but was supported by the reaction force of the second pad 4, causing pressure to concentrate on the user H's head at the position of the second pad 4, making the user H more likely to experience discomfort. Therefore, the difference in hardness between the first pad 3 and the second pad 4 is preferably 5 or more and 35 or less, and more preferably 10 or more and 25 or less.

[0024] When using the HMD 100, the desirable length of the area where the first pad 3 and the second pad 4 are present in the direction along the circumference of the user H's head was measured. As a result of the measurement, it was found that when the length of the area where the first pad 3 and the second pad 4 are present is short, the reaction force between the first pad 3 and the second pad 4 is concentrated at a position close to the center of the user H's forehead. Furthermore, by comparing the length of the area where the first pad 3 and the second pad 4 are present when it is long and when it is short, it was found that a shorter length makes the wearing position more likely to shift. It was also found that if this length is too long, the second pad 4 will wrap around the side of the head significantly, causing discomfort. The optimal length is thought to be approximately 200 mm, which fits within the distance between the left and right temples on the forehead side of the user H in the direction along the circumference of the user H's head. To prevent the attachment unit 2 from rotating around the center of the forehead, a radius of approximately 10 mm or more is required from the center of the forehead, taking into consideration the thickness of the first pad 3 and the second pad 4 and the flexibility of the user H's skin. Therefore, the length of the area where the first pad 3 and the second pad 4 exist is preferably 20 mm or more. Furthermore, if the length of the area where the first pad 3 and the second pad 4 exist is too long, there is a possibility that the temples of the user H will be compressed. Therefore, the length of the area where the first pad 3 and the second pad 4 exist is preferably 250 mm or less, taking into consideration the length between the left and right temples on the forehead side of the user H.

[0025] We considered the vertical lengths of the first pad 3 and the second pad 4. Consider the use of a helmet, a common form of protective equipment. A helmet generally protects the wearer's head from impact by dispersing forces acting on the head. For this purpose, the pads provided inside the helmet are long in the vertical direction. However, if the vertical length is long, the pads also encase the wearer's hair, resulting in hair being present between the wearer's skin and the pad. This reduces the adhesion between the wearer's skin and the pad, making the pad more likely to slip against the wearer's skin. Because the primary purpose of a helmet is to protect the head and cushion impacts, helmets often do not take into consideration the pad's or the wearer's overall slippage. In such helmets, the vertical length of the pads is often approximately 60 mm or more. In contrast, with the wearing unit 2 of the HMD 100, there is little need to consider head protection or cushioning impacts, and minimizing slippage of the wearing unit 2 is prioritized. Therefore, it is preferable to minimize hair getting caught between the pad and the user H's skin. Through measurements, it was found that when the vertical length of the pad is 60 mm or more, hair tends to get in, and when it is 10 mm or less, the reaction force is concentrated in one place, making the user more likely to feel uncomfortable and the attachment part 2 more likely to slip off. Therefore, the vertical length of the first pad 3 and the second pad 4 is preferably 10 mm or more and 60 mm or less, and more preferably about 40 mm.

[0026] According to the first embodiment, the hardness of the first pad 3 that contacts the center of the forehead of the user H is higher than that of the first pad 4 that contacts the center of the forehead of the user H. Because the second pads 4, which are disposed on the left and right sides of the pad 3, have high hardness, the reaction force of the first pad 3 does not concentrate on the center of the user H's forehead. Furthermore, because the hardness of the second pad 4 is higher than that of the first pad 3, the reaction force at the position of the second pad 4 is higher than the reaction force at the position of the first pad 3. As a result, the reaction force of the second pad 4 becomes the main force that fixes the attachment unit 2. In the first embodiment, there are two main fulcrums for holding the attachment unit 2 on the user H's head, so the resistance to the rotational moment when the attachment unit 2 rotates relative to the head becomes large. The increased resistance to the rotational moment makes it less likely that the attachment unit 2 will be misaligned, allowing the user H to comfortably view the display unit 1. Furthermore, when the attachment unit 2 is worn, the first pad 3 collapses, widening the overall contact surface with the user H's forehead and dispersing the pressure, thereby reducing the feeling of oppression or discomfort.

[0027] (Embodiment 2) The second embodiment will be described in detail below with reference to the accompanying drawings. FIG. 4 is a top view illustrating a state in which pads are located on both the forehead and the back of the head. In FIG. 4, a user H wears the HMD 100, and a mounting unit 2 is provided on both the forehead and the back of the head of the user H. The two mounting units 2 provided on the forehead and the back of the head of the user H, respectively, are connected to each other by articulation units 5 provided on each of the user H's left and right temporal regions. In the mounting unit 2 provided on the forehead, a first pad 3 is disposed so as to correspond to the center of the user H's forehead, and in the mounting unit 2 provided on the back of the head, a first pad 3 is disposed so as to correspond to the center of the back of the head of the user H. On both the front and back mounting units 2, two second pads 4 are disposed so as to sandwich the first pad 3 in a direction along the circumference of the user H's head. The first pad 3 and two second pads 4 corresponding to the forehead and the back of the head are in contact with the user H's forehead. The first pad 3 and two second pads 4 corresponding to the back of the head are in contact with the back of the head of the user H. The articulated portions 5 are made of a member that has low rigidity and is stretchable in the front-rear direction. The articulated portions 5 are provided so that they can press each mounting unit 2 against the head of the user H by tension in the front-rear direction. The articulated portions 5 press each mounting unit 2 against the head of the user H, thereby holding each mounting unit 2 against the head of the user H. According to the second embodiment, the mounting units 2 are provided on both the front and back of the head of the user H, respectively, so that it is possible to prevent the HMD 100 and the display unit 1 from shifting at both the front and back of the head. Furthermore, according to the second embodiment, the pressing force can be distributed to both the front and back of the head of the user H, so that comfortable viewing is possible even when the clamping force on the head of the user H is relatively small compared to when using conventional HMDs.

[0028] (Embodiment 3) Hereinafter, the third embodiment will be described in detail with reference to the accompanying drawings. FIG. 5 is a top view illustrating a state in which the wearing unit 2 is not in contact with the temporal region of the user H. In FIG. 5, the user H wears the HMD 100, and the wearing unit 2 is provided to surround the user H's head. In the wearing unit 2, first pads 3 are arranged to correspond to the center of the user H's forehead and the center of the occipital region of the user H. In the direction along the circumference of the user H's head, two second pads 4 are arranged to sandwich the first pad 3 on each of the front and rear first pads 3. The first pad 3 and the two second pads 4 corresponding to the forehead and the occipital region of the user H are in contact with the user H's forehead. The first pad 3 and the two second pads 4 corresponding to the occipital region of the user H are in contact with the occipital region of the user H. The wearing unit 2 is a rigid body that surrounds the user H's head and is held on the user H's head by a tensioning mechanism (not shown). This allows the HMD 100 to be fixed to the user H's head without coming into contact with the temporal region of the user H. According to the third embodiment, the user H is less likely to feel discomfort or strangeness because the side of the head is not pressed. As a result, the side of the head of the user H is not in contact with any member regardless of the fastening force of the attachment unit 2, so that viewing can be done without feeling any pressure or discomfort on the side of the head.

[0029] (Embodiment 4) Hereinafter, the fourth embodiment will be described in detail with reference to the accompanying drawings. 6A is a top view showing a state in which a portion of a first pad 3 overlaps a portion of a second pad 4. In FIG. 6A, the first pad 3 and two second pads 4 are in contact with each other. The first pad 3 and two second pads 4 overlap so that a portion of the first pad 3 is positioned closer to the user H's head than a portion of the second pad 4. In this case, the thickness of the overlapping portion of the first pad 3 and the second pad 4 is approximately equal to the thickness of the portion where the first pad 3 and the second pad 4 do not overlap. The connection surface where the first pad 3 and the second pad 4 contact each other may be a single plane perpendicular to the up-down and left-right directions as shown in FIG. 6A, or it may not be. For example, the connection surface may be a curved surface or may be a plurality of discontinuous surfaces as shown in FIG. 6B. In addition, in the fourth embodiment, two second pads 4 overlap one first pad 3, but for example, one of the second pads 4 may overlap the first pad 3. According to the fourth embodiment, the user H is less likely to feel uncomfortable at the boundary between the first pad 3 and the second pad 4, and a comfortable viewing experience is possible.

[0030] (Embodiment 5) Hereinafter, the fifth embodiment will be described in detail with reference to the accompanying drawings. FIG. 7 is a top view of the state in which the third pad 6 is provided. In FIG. 7, the first pad 3 and the second pad 4 are in contact with each other, and the third pad 6 is located between the first pad 3, the two second pads 4, and the head of the user H. The entire surface of the third pad 6 on the side of the user H's head is in contact with the head of the user H. The third pad 6 may be formed with a hardness equal to or less than that of the first pad 3. According to the fifth embodiment, similar to the fourth embodiment, the user H is less likely to feel uncomfortable at the boundary between the first pad 3 and the second pad 4, enabling comfortable viewing. However, the first pad 3 and the second pad 4 are not limited to being in contact with each other as in the fifth embodiment, and the first pad 3 and the second pad 4 may be disposed apart from each other, for example.
