[0024] Figure 10 Illustrated examples of variations of wearable devices. Detailed Implementation

[0025] In the following text, specific embodiments in which this technology is applied will be described in detail with reference to the accompanying drawings.

[0026] Examples of wearable device components

[0027] refer to Figures 1-4 Examples of embodiments of wearable devices to which this technology is applied are described.

[0028] Figure 1 The illustration shows a perspective view of the wearable device 11 as seen from the upper left side. Figure 2 The illustration shows a perspective view of the wearable device 11 as viewed from the upper right side. Figure 3 The diagram illustrates the plan view of wearable device 11. Figure 4 The illustration shows a front view of the wearable device 11.

[0029] As illustrated in the diagram, the wearable device 11 is configured such that the right front unit 21R is connected to the rear unit 22 via the right ear hook portion 23R, and the left front unit 21L is connected to the rear unit 22 via the left ear hook portion 23L. A user can wear the wearable device 11 with the right ear hook portion 23R hooked to the right ear and the left ear hook portion 23L hooked to the left ear, allowing the rear unit 22 to pass through the back of the neck for AR functionality.

[0030] The right front unit 21R is positioned in front of the user's right ear when the user wears the wearable device 11, and includes a light guide plate 31, an optical engine block 32, a movable connection block 33, and a microphone block 34.

[0031] The light guide plate 31 is positioned in front of the right eyeball when the user wears the wearable device 11 and guides the image display light projected from the optical engine block 32 to the right eyeball. For example, the light guide plate 31 is made of transparent glass or resin, and the user can view the image formed by the image display light in a way that is superimposed on the surrounding environment.

[0032] The optical engine block 32 is formed by incorporating, for example, a light source, a microdisplay, a projection lens, etc., and uses a light guide plate 31 to project image display light for displaying images to the user.

[0033] For reference below Figure 8 and Figure 9 The movable connecting block 33 is connected to the optical engine block 32 and also to the microphone block 34, so that the light guide plate 31 and the optical engine block 32 can rotate about two axes with the center of the user's right eye as a reference.

[0034] The microphone block 34 is formed by incorporating a microphone, speaker, etc., and its rear end is fixed to the right ear hook portion 23R. For example, the microphone block 34 can be formed by, for example, Figure 2 As shown in the diagram, multiple circular holes formed in the microphone block 34 collect the user's voice, ambient sounds, etc. At a predetermined position inside the wearable device 11, the right side pad 41R and the cheekbone support 42 are attached to the microphone block 34.

[0035] The right-side pad portion 41R is formed to include a pad with cushioning properties. For example, such as... Figure 3 As shown in the diagram, the right side pad 41R is configured to protrude toward the interior of the wearable device 11, and the pad is configured to fit against the area near the front of the right ear when the user wears the wearable device (see description below). Figure 5 A slit is provided in the rear side of the right pad 41R, through which the sound output from the speaker incorporated in the microphone block 34 is transmitted to the user's right ear.

[0036] The cheekbone support 42 is made of a flexible, slender, plate-like component, for example, such as Figure 3 As shown in the diagram, the light guide plate 31 and the optical engine block 32 extend from the proximal portion to the distal portion of the wearable device 11, extending from the microphone block 34 toward the inside of the wearable device 11. The cheekbone support 42 is provided to support the weight of the right side of the wearable device 11, since the wearable device 11 is formed such that the weight is biased toward the right side where the light guide plate 31 and the optical engine block 32 are provided.

[0037] The cheekbone support 42 is formed such that when the user wears the wearable device 11, its distal portion fits against the vicinity of the right cheekbone (see description below). Figure 5 This provides stable support for the right anterior unit 21R. For example, the zygomatic support 42 is formed internally using a thin, elongated plate-like component such as aluminum or thermoplastic resin, and externally using a soft component such as silicone or polyurethane foam. This allows the zygomatic support 42 to be bent into appropriate shapes to accommodate various bone structures and maintain its curved shape.

[0038] The left front unit 21L is positioned in front of the left ear when the user wears the wearable device 11, and is formed with a switch block 35.

[0039] The switch block 35 is formed by incorporating a power switch, an operation switch, etc., and its rear end is fixed to the left ear hook portion 23L. Note that the switch block 35 also incorporates a microphone, a speaker, etc. At a predetermined position inside the wearable device 11, the left side pad portion 41L is attached to the switch block 35.

[0040] The left side pad portion 41L is formed to include a pad with cushioning properties. For example, such as... Figure 3 As shown in the diagram, the left pad 41L is configured to protrude toward the interior of the wearable device 11, and the pad is also configured to fit against the area near the front of the left ear when the user wears the wearable device (see description below). Figure 6 A slit is provided in the rear side of the left pad 41L, through which the sound output from the speaker in the incorporated switch block 35 is transmitted to the user's left ear.

[0041] The rear unit 22 is positioned behind both ears when the user wears the wearable device 11, and includes a main substrate 51, a battery block 52, and a neckband 53.

[0042] The main substrate 51 is formed by incorporating a main substrate for controlling the operation of, for example, the wearable device 11, with its front end fixed to the right ear hook portion 23R and its rear end fixed to one end of the neck strap 53. Note that the main substrate is electrically connected to at least the optical engine block 32.

[0043] The battery block 52 is formed by incorporating, for example, a battery for powering the wearable device 11, with its front end fixed to the left ear hook portion 23L and its rear end fixed to the other end of the neckband 53. Note that the battery powers at least the optical engine block 32.

[0044] The neckband 53 is formed by incorporating wires that electrically connect the main substrate block 51 and the right front unit 21R to the battery block 52 and the left front unit 21L, and couples the blocks arranged on the right side of the wearable device 11 to the blocks arranged on the left side of the wearable device 11. The neckband 53 is made of, for example, an elastomer having a force pointing inwards towards the inside of the wearable device 11, and can generate wearing pressure when the user wears the wearable device.

[0045] For example, when the user is not wearing the wearable device 11, the neckband 53 is in a curved shape such that the distance between the right front unit 21R and the left front unit 21L is less than the head. Then, the user expands the curved shape of the neckband 53 so that the distance between the right front unit 21R and the left front unit 21L is greater than the head, and puts on the wearable device 11 so that the head is sandwiched between the right front unit 21R and the left front unit 21L. In the wearable device 11 worn in this manner, the neckband 53 is configured to have a force that returns to its original curved shape, thus generating appropriate wearing pressure on the user's head.

[0046] As described above, the wearable device 11 is configured such that the right front unit 21R and the left front unit 21L are coupled through the rear unit 22, and can be easily put on and taken off, thereby further improving user-friendliness. For example, when the user does not need to use the wearable device 11 for a short period of time, the user can use the wearable device 11 by removing it from their head and hanging it around their neck. At this time, since the wearable device 11 is configured to clamp the user's head by the wearing pressure of the neck strap 53, the user can easily attach and detach the wearable device 11.

[0047] In addition, unlike traditional goggle-style wearable devices, wearable device 11 can avoid problems such as leaving pressure marks or causing discomfort due to tightness around the entire head.

[0048] The wearable device 11 includes a light guide plate 31 with a frameless structure. For example, in conventional eyeglass-style wearable devices, a frame is provided to support the periphery of the light guide plate, while the wearable device 11 is formed without such a frame. This allows the wearable device 11 to display an image formed by image display light in a way that is superimposed on the surrounding environment, without obstructing the user's view due to a frame or similar obstruction. Note that the light guide plate 31 is formed by attaching cover plates to both sides, while its outer periphery is chamfered for safety.

[0049] like Figure 3 As shown in the diagram, the wearable device 11 is configured such that the pad on the right side 41R protrudes from the microphone block 34 toward the interior of the wearable device 11, and the pad on the left side 41L protrudes from the switch block 35 toward the interior of the wearable device 11. Therefore, when worn by a user, the wearable device 11 has gaps between the right front unit 21R and the left front unit 21L and the sides of the user's face. Thus, for example, even when a user wearing glasses uses the wearable device 11, with the temples of the glasses passing through these gaps, the user can wear the wearable device 11 while wearing glasses.

[0050] Support structure for wearable devices

[0051] refer to Figure 5 and Figure 6 Describe the support structure when a user wears wearable device 11.

[0052] Figure 5 The illustration shows a right view of wearable device 11 in a state where it is worn by a user. Figure 6 The diagram illustrates the left view of a wearable device when it is worn by a user.

[0053] Wearable device 11 is configured to be fixed to the user's head by a support structure, such as... Figure 5 As shown in the diagram, the right side of the user's face is supported by four support points P11 to P14, and as... Figure 6 As shown in the diagram, the left side of the user's face is supported by three support points P21 to P23.

[0054] Support point P11 is the area near the front of the user's right ear where the right ear pad 41R is placed; support point P12 is the area near the upper side of the user's right ear root where the right ear hook 23R is placed; and support point P13 is the area near the back of the user's right ear root where the right ear hook 23R is placed.

[0055] Support point P14 is the location where the tip of the cheekbone support 42 fits against the area near the cheekbone on the right side of the user's face. For example, the cheekbone support 42 is configured such that support point P14 is located approximately directly below the center of gravity of the light guide plate 31, optical engine block 32, movable connecting block 33, and microphone block 34, and supports the weight of the right front unit 21R, which includes these components, in a balanced manner.

[0056] Support point P21 is the area where the left side pad 41L fits against the front of the user's left ear; support point P22 is the area where the left ear hook 23L fits against the upper side of the user's left ear root; and support point P23 is the area where the left ear hook 23L fits against the back side of the user's left ear root.

[0057] Therefore, by setting support points P11-P13 and P21-P23 symmetrically supporting both sides of the user's face, and support point P14 supporting the weight that is biased to the right due to the optical engine block 32, the wearable device 11 can improve its stability when worn by the user. This prevents the wearable device 11 from shaking and allows a stable image to be displayed to the user.

[0058] The wearable device 11 is also configured such that, when worn by a user, the weight of the blocks positioned in front of the ears and the weight of the blocks positioned behind the ears are substantially the same. This allows the wearable device 11 to achieve balanced weight distribution in the front-to-back direction when worn by a user, and further improves stability. Furthermore, when... Figure 5and Figure 6 As shown in the diagram, when viewed from the side, the wearable device 11 is configured such that the main substrate block 51, the battery block 52, and the neck strap 53 are positioned lower than the other blocks, thereby further lowering the center of gravity to improve stability.

[0059] The shape of wearable devices

[0060] refer to Figure 7 Describe the shape of the wearable device 11 when viewed from the side. Note that... Figure 7 In the description, the right front unit 21R and the left front unit 21L are collectively referred to as the front unit 21, and the right ear hook portion 23R and the left ear hook portion 23L are collectively referred to as the ear hook portion.

[0061] like Figure 7 As shown in the diagram, when viewed from the side, the wearable device 11 is tilted downwards such that a straight line L2 extends rearwards from the ear hook portion 23 along the rear unit 22 relative to a substantially horizontal straight line L1 extending forward from the ear hook portion 23 along the front unit 21. This allows the wearable device 11 to have a shape in which the rear unit 22 is tilted relative to the front unit 21 at an angle θ between the straight lines L1 and L2. That is, assuming the direction in which the front unit 21 is attached to the ear hook portion 23 is horizontal, the rear unit 22 is located lower than the front unit 21 and tilts downwards and rearwards to attach to the ear hook portion 23.

[0062] Therefore, when a user wears the wearable device 11, the rear unit 22 is positioned low behind the user's head (near the back of the head and between the neck) so as to be tilted below the ears. This allows for miniaturization of the wearable device 11 while ensuring sufficient space behind the user's ears or head, and avoids the rear unit 22 affecting the user's hairstyle. Furthermore, when the user uses a cochlear implant, hearing aid, etc., the wearable device 11 is configured such that the rear unit 22 can be positioned so as not to interfere with the cochlear implant, hearing aid, etc.

[0063] The wearable device 11 can employ a structure that allows the angle θ to be changed at the ear hook portion 23. That is, the wearable device 11 is shaped as shown in... Figure 7 The upper side of the structure has a large angle θ, but the rear unit 22 can be moved relative to the front unit 21, such that, as shown in the diagram... Figure 7 The angle θ shown on the lower side is relatively small. Of course, the wearable device 11 can be fixedly attached to the rear unit 22 by using the angle θ between the front unit 21 and the rear unit 22 as any angle θ within the range of angle θ shown in the diagram.

[0064] Note that if the angle θ between the front unit 21 and the rear unit 22 is too small, the wearable device 11 is expected to become unstable due to its high center of gravity. Conversely, if the angle θ between the front unit 21 and the rear unit 22 is too large, the rear unit 22 is expected to bump against the user's neck when the user looks up. Therefore, the wearable device 11 is preferably configured to have an angle θ in the range of 10° to 25°, more preferably in the range of 15° to 20°.

[0065] Mobile mechanisms of wearable devices

[0066] Reference Figure 8 and Figure 9 Describes the movable mechanism of wearable device 11.

[0067] As described above, the wearable device 11 is configured such that the light guide plate 31 and the optical engine block 32 can rotate around two axes with reference to the vicinity of the center of the user's right eyeball via the movable connecting block 33.

[0068] Figure 8 Figure A illustrates a top view of the light guide plate 31 and the optical engine block 32 from the side. Figure 8 The diagram B shows a right view near the light guide plate 31 and the optical engine block 32.

[0069] In the wearable device 11, the movable mechanism is configured such that the light guide plate 31, the optical engine block 32, and the movable connecting block 33 are arranged along the direction indicated by the white arrow, around a direction perpendicular to the light guide plate 31. Figure 8 The axis, as shown in the diagram A, rotates in the direction of the intersection of the dashed lines, for example, within a range of +4.5° to -4.5°. For example, a rotating hinge is built into the connection between the movable connecting block 33 and the microphone block 34, having a structure that allows sliding about this axis along an arc shown in the dashed diagram. This allows the light guide plate 31, the optical engine block 32, and the movable connecting block 33 to rotate relative to the microphone block 34 according to the movement of the rotating hinge.

[0070] In the wearable device 11, the movable mechanism is configured such that the light guide plate 31 and the optical engine block 32 are arranged along the direction indicated by the white arrow, around a direction perpendicular to the direction of the light guide plate 31 and the optical engine block 32. Figure 8 The axis, in the direction of the intersection of the orthogonal dashed lines shown in Figure B, rotates, for example, within the range of +90° to -90°, more preferably within the range of +7.5° to -7.5°. For example, a rotary hinge is built into the connection between the movable connecting block 33 and the optical engine block 32, having a structure that allows sliding about this axis along the arc shown in the dashed diagram. This allows the light guide plate 31 and the optical engine block 32 to rotate relative to the movable connecting block 33 according to the movement of the rotary hinge.

[0071] Wearable device 11 is configured such that when worn by a user, it is perpendicular to... Figure 8 The axis in the direction of the intersection of the lines drawn at the orthogonal point shown in diagram A and the perpendicular to the axis. Figure 8 The axis along the direction of the intersection of the orthogonal lines shown in diagram B is located near the center of the user's right eyeball. Thus, the wearable device 11 can rotate the light guide plate 31 and the optical engine block 32 around two axes with the center of the user's right eyeball as a reference.

[0072] Figure 9 The diagram illustrates a plan view of the wearable device 11, in which the user's right eye (Eye) is expected to be located when the user wears the wearable device 11, and the EyeBox, which indicates the range of the image formed by the image display light visible to the eye (Eye), is shown with a double-dotted line.

[0073] Figure 9 The central part of the diagram illustrates the state in which the light guide plate 31 and the optical engine block 32 are arranged in the reference position. Figure 9 The left-hand diagram illustrates the light guide plate 31 and the optical engine block 32, which are rotating to the left relative to the reference position. Figure 9 The right-hand diagram illustrates the light guide plate 31 and the optical engine block 32, which are rotating in a rightward direction relative to the reference position.

[0074] As shown in the figure, by rotating the light guide plate 31 and the optical engine block 32 relative to the center of the user's right eye (Eye), which serves as a reference point, the wearable device 11 can adjust the display position of the image formed by the image display light without deviating it from the EyeBox. The wearable device 11 is configured such that even when rotating the light guide plate 31 and the optical engine block 32 to adjust the display position of the image formed by the image display light, the distance from the user's right eye (Eye) to the light guide plate 31 remains constant. Therefore, the wearable device 11 can adjust the display position left and right while minimizing changes in the display distance (exit pupil distance) of the image formed by the image display light.

[0075] Similarly, when the wearable device 11 is viewed from the side, the light guide plate 31 and the optical engine block 32 are rotated with reference to the center of the user's right eye (see...). Figure 8 (B) can minimize the variation in the display distance of the image formed by the display light, thereby allowing the display position to be adjusted up and down.

[0076] By forming a movable mechanism, the light guide plate 31 and the optical engine block 32 are arranged about the axis of rotation of the optical engine block 32 at the center rear of the optical engine block 32 (e.g., Figure 8 A upwards, Figure 8(From B to the left), it can also make wearable device 11 more streamlined.

[0077] Variations of wearable devices

[0078] refer to Figure 10 This describes a variation of the wearable device 11.

[0079] exist Figure 10 In the wearable device 11A shown in the diagram, and Figure 1 The components common to the wearable device 11 are indicated by the same reference numerals, and their detailed descriptions are omitted.

[0080] That is, through a structure including a right ear hook portion 23R, a left ear hook portion 23L, a light guide plate 31, an optical engine block 32, a movable connecting block 33, a microphone block 34, a switch block 35, a right side pad portion 41R, a left side pad portion 41L, and a cheekbone support member 42, similar to Figure 1 The wearable device 11 forms wearable device 11A.

[0081] On the other hand, wearable device 11A and Figure 1 The wearable device 11 shown in the diagram differs in that the neckband 53R is connected to the right ear hook portion 23R, the neckband 53L is connected to the left ear hook portion 23L, and a substrate battery block 61 is disposed between the neckband 53R and the neckband 53L.

[0082] The substrate battery block 61 is constructed by incorporating separately incorporated battery cells. Figure 1 The main substrate block 51 and the main substrate and battery in the battery block 52 are formed. That is, the substrate battery block 61 is formed by... Figure 1 The main substrate block 51 and the battery block 52 are integrated into a single unit.

[0083] and Figure 1 Similar to wearable device 11, wearable device 11A can further improve user-friendliness. In addition, wearable device 11A can also achieve a lower center of gravity through the substrate battery block 61, thereby improving stability when worn by the user.

[0084] Note that this embodiment describes a structure in which the light guide plate 31 and optical engine block 32 are arranged on the right side of the user's head to project image display light to the user's right eye. However, this structure can also be reversed by swapping the left and right sides. That is, the wearable device 11 can be configured such that the light guide plate 31 and optical engine block 32 are arranged on the left side of the user's head so that image display light is projected to the user's left eye. Note that the wearable device 11 can also be configured such that the light guide plate 31 and optical engine block 32 are provided on both sides to allow image display light to be projected to both of the user's eyes.

[0085] Alternatively, the wearable device 11 can be configured such that the arrangement of the microphone block 34 and the switch block 35 is interchanged, with the microphone block 34 located in the left front unit 21L and the switch block 35 located in the right front unit 21R. A bone conduction speaker can be used as the speaker incorporated into the microphone block 34 and the switch block 35. In this case, sound can be transmitted through the pads on the right side pad 41R and the left side pad 41L, which are in contact with the area near the front of the left and right ears.

[0086] Note that, provided there is no contradiction, each of the various techniques described in this specification can be implemented independently in a single component. Of course, any of the various techniques can also be combined. For example, part or all of the techniques described in any embodiment can be combined with part or all of the techniques described in other embodiments. Any part or all of the foregoing techniques can be combined with other techniques not described above.

[0087] Examples of combinations

[0088] Note that this technology can be configured as described below.

[0090] A front unit, comprising at least an optical engine block and a light guide plate, wherein the optical engine block is configured to project image display light for displaying an image to a user, and the light guide plate is configured to guide the image display light to the user's eyes, and the front unit is positioned in front of the user's ears when the user wears the wearable device; and

[0091] The rear unit, comprising at least a substrate block in which a substrate is incorporated and a battery block in which a battery is incorporated, is positioned behind the user's ears when the wearable device is worn.

[0092] In the aforementioned front unit, a right front unit positioned in front of the user's right ear and a left front unit positioned in front of the user's left ear are independently provided, and

[0093] The right front unit and the left front unit are coupled through the rear unit.
