Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 591,088, filed on October 17, 2023, entitled “Charging Case with Retention Mechanism for Retaining and Facilitating Charging of Smart Glasses Via Nose Bridge of Smart Glasses,” and U.S. Non-Provisional Patent Application No. 18 / 791,341, filed on July 31, 2024, the disclosures of which are incorporated herein by reference in their entirety. Technical Field

[0003] The present disclosure generally relates to a portable charging box that is configured to charge a pair of smart glasses (e.g., head-mounted augmented reality glasses) when the pair of smart glasses are secured into the portable charging box, the portable charging box including components configured to ensure that the pair of smart glasses remain in contact with charging contacts of the portable charging box. Background Art

[0004] Conventional smart glasses require frequent charging due to their compact nature and high power requirements. These limitations pose a problem for users who wish to use smart glasses in public (i.e., not at home) because of the inconvenience of worrying about finding a power outlet in an unfamiliar location and then being tethered to that charging location for a significant period of time. Even if the device can be charged using a mobile battery charger, ensuring that the glasses continue to charge while they are being moved can be a problem because the charging connection may be disconnected.

[0005] Therefore, there is a need to address one or more of the above challenges. A brief summary of solutions to the above problems is described below. Summary of the invention

[0006] The exemplary portable charging case described herein solves the above-mentioned problems, including being able to charge a pair of smart glasses while on the go and ensuring uninterrupted charging when the pair of smart glasses are charged within the portable charging case. Uninterrupted charging is ensured by one or more components described herein, which are configured to hold the smart glasses in a position so that the charging contacts of the portable charging case remain in contact regardless of orientation. In addition, it is convenient to have the charging case include a battery configured to charge the battery of a pair of smart glasses because the user can extend the interval between the needs to plug the portable charging case into a power source.

[0007] An example of a portable charging case for smart glasses (e.g., see FIG. 1A to FIG. 5D The portable charging case described in any of the figures in FIG. 1 includes a glasses holding portion of the charging case (e.g., Figure 1A and Figure 1B The glasses holding portion 106 is shown to have a shape that follows the contour of the inner surface 120 of the charging case, the portable charging case being, for example, a smart glasses case that largely reflects the appearance and shape of a traditional glasses case, the glasses holding portion defining a contour along the inner surface of the portable charging case (e.g., a leaf spring component or a component including a spring (e.g., a leaf spring, a torsion spring, a coil spring, etc.)). The glasses holding portion is configured to apply resistance to firmly hold the smart glasses along the contour (e.g., reference FIG. 1A to FIG. 5D In some embodiments, the glasses holding portion is a portable charging case, such that the material of the charging case is configured to apply resistance by being able to deflect to securely hold the smart glasses along the contour. In this embodiment, fewer parts are required and the charging case can be made smaller. The portable charging case also includes a holding bracket (e.g., Figure 1A to Figure 1B A glasses holding bracket 108 is shown, Figure 2 A glasses holding bracket 200 is shown, Figure 3 A glasses holding bracket 300 is shown, Figure 4 A deployable mechanism 401 is shown as a retaining bracket, Figure 5A A holding bracket 501 is shown, which is connected to a glasses holding portion (e.g., Figure 1A to Figure 1B The eyeglass holding portion 106 is shown, Figure 2 The eyeglass holding portion 204 is shown, Figure 3 The eyeglass holding portion 302 is shown, Figure 4 and Figure 5A 502) is shown to be coupled to the glasses holding bracket, which may include an outer / inner protective surface of the portable charging case 500, and the glasses holding bracket is configured to be coupled to the nose pads of the smart glasses (e.g., reference FIG. 1A to FIG. 5DThe nose pads 112A and 112B described above apply force to hold the smart glasses in place, thereby facilitating the charging case's electrical contacts (e.g., Figure 1A and Figure 1B In some embodiments, the retaining bracket is configured to mate with a detent on the smart glasses so that when the smart glasses are fully inserted, the retaining bracket rests in the detent, thereby ensuring that less movement occurs when the smart glasses are fully inserted.

[0008] In another exemplary embodiment, a portable charging case for smart glasses includes a cavity configured to accommodate a pair of smart glasses. The portable charging case also includes a cover and a clasp, the cover being configured to enclose the cavity, the clasp attaching the cover to another portion of the portable charging case. The portable charging case also includes a light integrated into the portion of the clasp to which the other portion of the portable charging case is attached, and the light is configured to provide (i) charging status information of the portable charging case and (ii) charging status information of a pair of smart glasses inserted into the cavity. The charging status information may indicate whether the charging case has power, whether the charging case is charging, whether the glasses have power, whether the glasses are charging, or a combination of charging statuses. For example, FIG. 8A to FIG. 9 A portable charging case is shown included, the buckle having an integrated light that indicates the charging status of the portable charging case and the charging status of a pair of smart glasses enclosed within the charging case.

[0024] Numerous details are described herein to provide a thorough understanding of the exemplary embodiments shown in the accompanying drawings. However, some embodiments may be practiced without many of these specific details, and the scope of the claims is limited to only those features and aspects specifically recited in the claims. In addition, well-known processes, components, and materials are not necessarily described in detail to avoid obscuring the relevant aspects of the embodiments described herein.

[0025] Embodiments of the present disclosure may include artificial reality systems of various types or embodiments, or may be implemented in combination with artificial reality systems of various types or embodiments. As described herein, artificial reality (AR) is any superimposed functionality and / or sensory perceptible presentation provided by an artificial reality system within a user's physical environment. Such artificial reality may include and / or represent virtual reality (VR), augmented reality, mixed artificial reality (MAR), or some combination thereof and / or a variation of one of them. For example, a user may perform an air swipe gesture to skip a song by providing an application programming interface (API) for a song: the API provides playback at, for example, a home speaker. The AR environment described herein includes, but is not limited to: VR environments (including non-immersive VR environments, semi-immersive VR environments, and fully immersive VR environments); augmented reality environments (including marker-based augmented reality environments, markerless augmented reality environments, location-based augmented reality environments, and projection-based augmented reality environments); mixed reality; and other types of mixed reality environments.

[0026] Artificial reality content may include fully generated content or generated content combined with captured (e.g., real-world) content. Artificial reality content may include video, audio, haptic events, or some combination thereof, any of which may be presented in a single channel or in multiple channels (such as stereoscopic video that produces a three-dimensional effect to the viewer). In addition, in some embodiments, artificial reality may also be associated with applications, products, accessories, services, or some combination thereof, which are used, for example, to create content in the artificial reality and / or otherwise be used in the artificial reality (e.g., to perform activities in the artificial reality).

[0027] As described herein, gestures may include air gestures, surface contact gestures, and / or other gestures that can be detected and determined based on the movement of a single hand (e.g., a single-handed gesture performed by a user's hand detected by one or more sensors of a wearable device (e.g., electromyography (EMG) and / or an inertial measurement unit (IMU) of a wrist wearable device) and / or detected via image data collected by an imaging device of the wearable device (e.g., a camera of a head wearable device)) and other gestures that can be detected and determined based on the combined movement of the user's hands. In some embodiments, air means that the user's hand does not contact a surface, object, or part of an electronic device (e.g., a head wearable device or other communicatively coupled device, such as a wrist wearable device). In other words, the gesture is performed in open air in 3D space and does not contact a surface, object, or electronic device. More generally, surface contact gestures (contact at a surface, object, user body part, or electronic device) are also contemplated in which contact (or intent to contact) is detected at a surface (e.g., a single-finger tap or a double-finger tap on a table, on a user's hand or another finger, on a user's lap, on a sofa, on a steering wheel, etc.). The different gestures disclosed herein can be detected using image data and / or sensor data (e.g., neuromuscular signals sensed by one or more biopotential sensors (e.g., EMG sensors) or other types of data from other sensors (such as proximity sensors, time-of-flight (ToF) sensors, sensors of inertial measurement units, etc.)) detected by a wearable device worn by a user and / or other electronic devices owned by the user (e.g., a smartphone, a laptop, an imaging device, an intermediate device, and / or other devices described herein).

[0028] As described herein, a portable charging case configured to protect and charge a pair of smart glasses similar to those described above will be discussed in detail. Figure 1A and Figure 1B Components of a portable charging case configured to charge smart glasses are shown in accordance with some embodiments. Figure 1A A series 100 is shown showing the smart glasses 102 being inserted into a portable charging case 104 . Figure 1A Also shown is how the glasses retaining portion 106 and the glasses retaining bracket 108 operate together to ensure that the smart glasses 102 are retained in the portable charging case for charging.

[0029] The first step 110 of the sequence is shown, where the smart glasses 102 have just begun to be inserted into the portable charging case 104. As shown in the first step 110, the glasses holding bracket 108 has a cylindrical shape, and the cylindrical shape is configured so that the glasses holding bracket can move along the nose pads 112A and 112B of the smart glasses.

[0030] In order to move the glasses holding bracket 108 along the nose pads 112A and 112B, the glasses holding bracket 108 is coupled to the glasses holding portion 106 that is at least partially configured to bend. For example, the glasses holding portion 106 is a leaf spring 114 that is coupled to the charging box (or to the intermediate component 117 of the charging box) at one end 116, and the other end 118 of the leaf spring is coupled to the glasses holding bracket 108. In some embodiments, the glasses holding portion 106 has a shape that follows the contour of the inner surface 120 of the charging box.

[0031] A second step 122 of the sequence is shown, where the smart glasses 102 are partially inserted into the portable charging case 104. As shown in the second step 122, the nose pads 112A and 112B move along the glasses holding bracket 108 and ultimately deflect (e.g., bend) the glasses holding portion 106 (e.g., leaf spring 114).

[0032] The third step 124 shows that the smart glasses 102 are fully inserted into the portable charging box 104. As shown in the third step 124, the nose pads 112A and 112B no longer push the glasses holding bracket 108, and the glasses holding portion 106 (e.g., the leaf spring 114) eventually returns to its resting state. In some embodiments, the resting state includes at least some preload on the leaf spring to ensure that a predetermined resistance is maintained. Once the smart glasses 102 are fully inserted, the charging pads on the smart glasses 102 contact the charging contacts 126A and 126B of the charging box, which can be spring-loaded charging contacts configured to charge the smart glasses 102. The glasses holding bracket 108 combines the spring-loaded contacts and the glasses holding bracket 108 so that the portable charging box 104 can continuously charge the smart glasses 102 in any orientation. The shape of the nose pads is such that when fully inserted, the glasses holding bracket contacts the nose pads and the glasses holding portion is in its undeflected state.

[0033] Figure 1B An exploded view of the eyeglass holding bracket 108 and the eyeglass holding portion 106 including the intermediate member 117 is shown in accordance with some embodiments. Figure 1B The eyeglass retaining bracket 108 is shown coupled to the eyeglass retaining portion 106 via one or more fasteners 128. In some embodiments, the eyeglass retaining bracket 108 and the eyeglass retaining portion 106 are integrally formed with one another. Figure 1B The glasses retaining portion 106 is also shown coupled to the intermediate component 117 via one or more additional fasteners 132. In some embodiments, the intermediate component 117 includes a cavity 128 configured to accommodate one or more electronic components for charging the smart glasses 102. In some embodiments, the intermediate component 117 includes a magnet 130 configured to further control the movement of the glasses retaining portion 106 (e.g., by controlling the movement of a leaf spring, wherein a portion of the leaf spring 114 is made of a ferrous material). In some embodiments, the magnet 130 is coupled to the leaf spring 114 and the intermediate component 117 is made of a ferrous material.

[0034] Figure 2 An alternative embodiment is shown in which the glasses retaining bracket 200 has a rounded rectangular surface 202 according to some embodiments. In some embodiments, the rounded rectangular surface 202 is selected to control the tactile sensation felt at the smart glasses 102 when the smart glasses 102 are inserted into the portable charging case 104 (not shown). Figure 2Also shown is a glasses holding portion 204 coupled to the glasses holding bracket 200. In this example, the glasses holding portion 204 itself is not a leaf spring and can be made of the same material as the glasses holding bracket 200. In this example, the glasses holding bracket can include a coil spring or a torsion spring (not shown, see Figure 3 As an example, a torsion spring is used to control the movement of the glasses holding bracket 200 when the smart glasses 102 are inserted into the charging box. Figure 2 Another intermediate portion 206 is also shown, which may be configured to Figure 3 The coil springs shown work together.

[0035] Figure 3 Another glasses retaining bracket 300, glasses retaining portion 302, and release mechanism 304 configured to eject smart glasses 102 are shown in accordance with some embodiments. Figure 3 The middle portion 306 is shown coupled to the glasses charging case 300, and the glasses holding portion 302 is coupled to the middle portion 306 via a hinge 308. The hinge 308 includes a torsion spring 310 configured to control movement of the glasses holding portion 302 relative to the middle portion 306 (e.g., rotation of the glasses holding portion 302 about the hinge 308). Figure 3 The glasses holding portion 302 is shown coupled to the glasses holding bracket 300, and the glasses holding bracket 300 has a triangular surface 314. In some embodiments, the torsion spring is configured to maintain the surface of the glasses holding portion 302 in contact with the middle portion 306 in its static state. In some embodiments, the static state includes: the torsion spring has a preload, which ensures that the smart glasses remain in place after insertion.

[0036] Figure 3 Further shown is a release mechanism 304 configured to eject the smart glasses 102 from the portable charging case 104. The release mechanism can be activated via a button 316 placed on an exterior portion of the portable charging case 104. In some embodiments, the release mechanism is configured to push the button 316 against a portion 318 of the torsion spring 310 via a coil spring 320 or another component to cause rotation of the glasses retaining portion 302, which allows the smart glasses 102 to be ejected and / or more easily removed from the portable charging case 104. The release mechanism can be configured to work with the other embodiments described.

[0037] Figure 3 Also shown are charging contacts 332A and 332B being at least partially held in place by springs 334A and 334B, respectively, which ensure that the charging contacts 332A and 332B remain in contact with the electrical contacts on the bridge of the smart glasses 102. Figure 3The eyeglass retaining bracket 300 is also shown to have a triangular surface 336 .

[0038] Figure 4 Another embodiment of a glasses holding bracket and glasses holding portion according to some embodiments is shown, wherein the glasses holding bracket includes a deployable mechanism configured to retain the smart glasses within a portable charging case. Figure 4 The first pane 400 shows the deployable mechanism 401 in its undeployed state (e.g., the two spring-loaded posts 404A and 404B are in an unextended state), and the second pane 402 shows the deployable mechanism 401 in its deployed state (e.g., the two spring-loaded posts 404A and 404B are in an extended state). A rear view 406 is shown to illustrate the deployable mechanism 401 and how it is spring loaded via spring 406. In some embodiments, multiple springs may be used. The deployable mechanism 401 is configured so that when the smart glasses 102 are fully inserted into the portable charging case 104, they are in the deployed state shown in the second pane 402, so that the smart glasses are held in place by the two spring-loaded posts 404A and 404B.

[0039] Figure 5AAnother embodiment is shown in which the retaining bracket 501 and the eyeglass retaining portion 502 are coupled to the portable charging case 500 such that the eyeglass retaining portion 502 does not move relative to the portable charging case 500 in accordance with some embodiments. In this example, the deflection shown in the previously described examples instead occurs at the portable charging case, for example, the material of the portable charging case acts as a spring (e.g., by having a flexible center portion (e.g., a polymer shell (e.g., a polycarbonate shell, an acrylonitrile-butadiene-styrene copolymer (ABS) shell, etc.), a composite material (e.g., a polycarbonate with glass fiber), etc.). When the portable charging case is made of a material that can elastically deform when the smart glasses 102 are inserted into the portable charging case 500, the portable charging case acts as a spring. In other words, when the nose pads 112A and 112B pass over the retaining bracket 501, the portable charging case deflects. After the nose pads 112A and 112B pass over the retaining bracket 501, the portable charging case 500 returns to its undeflected state. When the portable charging case 500 is in its undeflected state, the charging case provides sufficient pressure to keep the smart glasses in contact with the charging contacts while the portable charging case 500 is in its undeflected state. The charging box 500 can be in any physical orientation (e.g., sideways, inverted, etc.). In some embodiments, the portable charging box 500 is produced in part or in whole using various materials that produce desired textures and / or rely on sustainable materials. In some embodiments, the exterior of the portable charging box is made of completely sustainable materials, or the sustainable material is a layer that provides a desired decorative finish (e.g., a finish using natural materials, recycled materials, etc.). In some embodiments, the selected material can be used to further control the amount of elastic deformation that occurs when the smart glasses 102 are inserted and removed. In some embodiments, the portable charging box 500 does not include a battery for mobile charging and serves as a traditional glasses holder, but is still configured to charge the smart glasses when the charger is inserted into the portable charging box 500. By building the charging connector into the charging box, charging contacts can be used on the smart glasses instead of large traditional connectors (e.g., USB type-c ports) to better control the size of the smart glasses. In some embodiments, the portable charging box 500 includes a battery for mobile charging (i.e., charging when not plugged into a constant power source (e.g., a wall socket)).

[0040] Figure 5A The portable charging case is also shown to include an indicator light 514 (e.g., a multi-color LED) that is configured to illuminate to communicate different charging states of the portable charging case (e.g., indicating that the charge level of the charging case is above or below a threshold charge state (e.g., 20% or a battery capacity configured to be capable of providing a full charge to the smart glasses), indicating that the charging case is charging, indicating the charge level of a battery located in the smart glasses contained within the charging case, etc.).

[0041] Figure 5B A back side 504 of a portable charging case 500 is shown according to some embodiments. Figure 5B It is shown that in this embodiment, the portable charging case does not completely enclose the smart glasses 102. For example, the portable charging case is configured to cover sensitive portions of the smart glasses (e.g., lenses and electronic components located within the bridge of the nose). In some embodiments, FIG. 5A to FIG. 5D The portable charging box is configured to cover the entire smart glasses 102.

[0042] Figure 5C According to some embodiments FIG. 5A to FIG. 5B A cross-sectional view 506 of the portable charging case 500 is shown. Figure 5C It is shown that the holding bracket 501 and the glasses holding portion 502 can be permanently formed with the portable charging box. In some embodiments, the holding bracket 501 is directly attached to and contacts the portable charging box 500 (ie, not attached to the glasses holding portion 502). Figure 5C The portable charging case 500 is shown to include a charging port 508 (e.g., a USB Type-C port), and the portable charging case 500 is configured to receive power and transmit the power to one or more pogo pins 510 for contacting the smart glasses 102.

[0043] Figure 5D A decorative covering that may be placed on a portable charging case 500 is shown in accordance with some embodiments. Figure 5D A decorative exterior 512 of a portable charging case is shown that can be attached, for example, via lamination. In this example, the decorative exterior 512 is made of a natural material (e.g., leaves) and has a design corresponding to leaves. In some embodiments, the decorative portion covers only the exterior (e.g., surfaces that do not contact the lenses of the smart glasses), but in other embodiments, the decorative portion is also present on at least one interior surface of the portable charging case 500 (e.g., surfaces that contact the lenses of the smart glasses). In some embodiments, the interior material is a microfiber or synthetic suede so that the lenses of the smart glasses are not damaged by contact with the portable charging case 500 during insertion and removal. In some embodiments, the interior material is configured to cover at least a portion of the glasses retaining portion 502 so that the interior appears seamless when fully assembled. In some embodiments, the exterior material can be a synthetic leather, a natural leather, a woven or knitted material, a plastic material, and / or a sustainable material (e.g., recycled plastic-derived materials, organic materials (e.g., bamboo), etc.). The above-described decorative coverings are also applicable to reference Figures 1A to 4Other portable charging cases described. In some embodiments, a single pair of smart glasses can be configured to work with any of the charging cases described above, for example, if the user expects to be away from the charger for a long time, the user can use a portable charging case that includes a portable battery, or when the user wants to use a lighter carrying case, the user can use a portable charging case that does not include a portable battery.

[0044] (A1) According to some embodiments, a portable charging case for smart glasses (e.g., referring to FIG. 1A to FIG. 5D The portable charging box described in any of the figures in the figure) includes a glasses holding portion of the charging box (for example, FIG. 1 shows that the glasses holding portion 106 has a shape that follows the contour of the inner surface 120 of the charging box), the portable charging box is, for example, a smart glasses box that largely reflects the appearance and shape of a traditional glasses box, and the glasses holding portion defines a contour along the inner surface of the portable charging box (for example, a leaf spring component or a component including a spring (for example, a leaf spring, a torsion spring, a coil spring, etc.)), wherein the glasses holding portion is configured to apply resistance to firmly hold the smart glasses along the contour (for example, reference FIG. 1A to FIG. 5D In some embodiments, the glasses holding portion is a portable charging case, such that the material of the charging case is configured to apply resistance by being able to deflect to securely hold the smart glasses along the contour. In this embodiment, fewer parts are required and the charging case can be made smaller. The portable charging case also includes a holding bracket (e.g., Figure 1A to Figure 1B A glasses holding bracket 108 is shown, Figure 2 A glasses holding bracket 200 is shown, Figure 3 A glasses holding bracket 300 is shown, Figure 4 A deployable mechanism 401 is shown as a retaining bracket, Figure 5A A holding bracket 501 is shown, which is connected to a glasses holding portion (e.g., Figure 1A to Figure 1B The eyeglass holding portion 106 is shown, Figure 2 The eyeglass holding portion 204 is shown, Figure 3 The eyeglass holding portion 302 is shown, Figure 4 and Figure 5A 502) is shown to be coupled to the glasses holding bracket, which may include an outer / inner protective surface of the portable charging case 500, and the glasses holding bracket is configured to be coupled to the nose pads of the smart glasses (e.g., reference FIG. 1A to FIG. 5D The nose pads 112A and 112B described above apply force to hold the smart glasses in place, thereby facilitating the charging case's electrical contacts (e.g., Figure 1AIn some embodiments, the retaining bracket is configured to mate with a stopper on the smart glasses so that when the smart glasses are fully inserted, the retaining bracket rests in the stopper, thereby ensuring that less movement occurs when the smart glasses are fully inserted.

[0045] (A2) In some embodiments of A1, the electrical contacts of the charging case are spring pins (e.g., the electrical contacts are coupled to springs to push the electrical contacts into the electrical contacts of the smart glasses, i.e., charging can continue regardless of the spatial orientation of the charging case and the smart glasses). In some embodiments, the spring pins are configured to maintain electrical connection with electrical contacts on the smart glasses (e.g., on the nose pads or bridge of the smart glasses) for charging (e.g., charging the battery of the smart glasses via another battery located in the charging case). For example, Figure 3 The charging contacts 332A and 332B are shown to be at least partially held in place by springs 334A and 334B, respectively, and the springs ensure that the charging contacts 332A and 332B remain in contact with the electrical contacts on the bridge of the smart glasses 102.

[0046] (A3) In some embodiments of any one of A1 to A2, the glasses holding bracket is a cylindrical rod (e.g., wherein the cylindrical rod is configured to extend along the contour of the nose pad of the smart glasses). Figure 1A to Figure 1B Both show a glasses holding bracket 108 having a cylindrical shape.

[0047] (A4) In some embodiments of any one of A1 to A2, the glasses holding bracket has a rounded rectangular surface (e.g., wherein the rounded rectangular surface is configured to extend along the contour of a nose pad of the smart glasses). Figure 2 The eyeglass holding bracket 200 is shown having a rounded rectangular surface 202 .

[0048] (A5) In some embodiments of any one of A1 to A2, the glasses retaining bracket has a triangular surface (e.g., wherein the triangular surface conforms to the shape of the nose pad and nose bridge of the smart glasses). Figure 3 The eyeglass retaining bracket 300 is also shown to have a triangular surface 336 .

[0081] Example AR System

[0082] Fig. 6A and Figure 6B An exemplary AR system is shown in accordance with some embodiments. Fig. 6A A first AR system 600a and a first exemplary user interaction using a wrist wearable device 603 , a head wearable device (eg, AR device 700 ), and / or a handheld intermediate processing device (HIPD) 607 are shown. Figure 6B A second AR system 600b is shown, along with a second exemplary user interaction using the wrist wearable device 603, the AR device 700, and / or the HIPD 607. As will be appreciated by those skilled in the art upon reading the description provided herein, the above-described exemplary AR systems (described in detail below) can perform various functions and / or operations.

[0083] Fig. 6A A user 602 is shown wearing a wrist wearable device 603 and an AR device 700, and a HIPD 607 is placed on the user's desk. The wrist wearable device 603, the AR device 700, and the HIPD 607 facilitate the user's interaction with the AR environment. In particular, as shown in the first AR system 600a, the wrist wearable device 603, the AR device 700, and / or the HIPD 607 enable the presentation of one or more avatars 604, digital representations 606 of contacts, and virtual objects 608. As described below, the user 602 can interact with one or more avatars 604, digital representations 606 of contacts, and virtual objects 608 via the wrist wearable device 603, the AR device 700, and / or the HIPD 607.

[0084] The user 602 can provide user input using any of the following: wrist wearable device 603, AR device 700, and / or HIPD 607. For example, the user 602 can perform one or more gestures to provide user input, and the one or more gestures are detected by the wrist wearable device 603 (e.g., using one or more EMG sensors and / or IMUs) and / or by the AR device 700 (e.g., using the AR device described below). Figure 7A to Figure 7B-1 and Figure 7B-2Alternatively or additionally, the user 602 can provide user input through one or more touch surfaces of the wrist wearable device 603, the AR device 700 and / or the HIPD 607 and / or voice commands collected by microphones of the wrist wearable device 603, the AR device 700 and / or the HIPD 607. In some embodiments, the wrist wearable device 603, the AR device 700 and / or the HIPD 607 include a digital assistant to help the user provide user input (e.g., complete a sequence of operations, suggest different operations or commands, provide reminders, or confirm commands). In some embodiments, the user 602 can provide user input through one or more facial gestures and / or facial expressions. For example, the camera of the wrist wearable device 603, the AR device 700 and / or the HIPD 607 can track the eyes of the user 602 to navigate the user interface.

[0085] The wrist wearable device 603, the AR device 700, and / or the HIPD 607 can operate alone or in combination to allow the user 602 to interact with the AR environment. In some embodiments, the HIPD 607 is configured to operate as a central hub or control center for the wrist wearable device 603, the AR device 700, and / or another communication coupling device. For example, the user 602 can provide input to interact with the AR environment at any one of the wrist wearable device 603, the AR device 700, and / or the HIPD 607, and the HIPD 607 can identify one or more back-end tasks and front-end tasks to perform the requested interaction and distribute instructions to perform one or more back-end tasks and front-end tasks at the wrist wearable device 603, the AR device 700, and / or the HIPD 607. In some embodiments, the back-end task is a background processing task that is not perceptible to the user (e.g., rendering content, decompression, or compression), and the front-end task is a user-perceptible user-oriented task (e.g., presenting information to the user, or providing feedback to the user, etc.). HIPD 607 can perform backend tasks and provide operation data corresponding to the performed backend tasks to wrist wearable device 603 and / or AR device 700, so that wrist wearable device 603 and / or AR device 700 can perform frontend tasks. In this way, HIPD 607, which has more computing resources and greater thermal headroom than wrist wearable device 603 and / or AR device 700, performs computing-intensive tasks and reduces computer resource utilization and / or power usage of wrist wearable device 603 and / or AR device 700.

[0086] In the example shown in the first AR system 600a, the HIPD 607 identifies one or more backend tasks and frontend tasks associated with the following user request and distributes instructions to cause the one or more backend tasks and frontend tasks to be performed: a user request to initiate an AR video call with one or more other users (represented by the avatar 604 and the digital representation 606 of the contact). In particular, the HIPD 607 performs the backend tasks for processing and / or rendering image data (and other data) associated with the AR video call, and provides the AR device 700 with the operating data associated with the performed backend tasks, so that the AR device 700 performs the frontend tasks for presenting the AR video call (e.g., presenting the avatar 604 and the digital representation 606 of the contact).

[0087] In some embodiments, HIPD 607 can be operated as a focus or anchor point for information presentation. This allows user 602 to know generally where the information is presented. For example, as shown in the first AR system 600a, avatar 604 and digital representation 606 of the contact are presented above HIPD 607. In particular, HIPD 607 and AR device 700 operate in combination to determine the location for presenting avatar 604 and digital representation 606 of the contact. In some embodiments, information can be presented within a predetermined distance (e.g., within five meters) from HIPD 607. For example, as shown in the first AR system 600a, virtual object 608 is presented on a table at a distance from HIPD 607. Similar to the above example, HIPD 607 and AR device 700 can be combined to operate to determine the location for presenting virtual object 608. Alternatively, in some embodiments, the presentation of information is not constrained by HIPD 607. More specifically, the avatar 604 , the digital representation of the contact 606 , and the virtual object 608 do not have to be presented within a predetermined distance of the HIPD 607 .

[0088] User input provided at the wrist wearable device 603, the AR device 700, and / or the HIPD 607 is coordinated so that the user can use any device to start an operation, continue an operation, and / or complete an operation. For example, the user 602 can provide user input to the AR device 700 to cause the AR device 700 to present a virtual object 608, and when the virtual object 608 is presented by the AR device 700, the user 602 can provide one or more gestures via the wrist wearable device 603 to interact with and / or manipulate the virtual object 608.

[0089] Figure 6BThe user 602 is shown wearing the wrist wearable device 603 and the AR device 700 and holding the HIPD 607. In the second AR system 600b, the wrist wearable device 603, the AR device 700, and / or the HIPD 607 are used to receive one or more messages and / or provide one or more messages to contacts of the user 602. In particular, the wrist wearable device 603, the AR device 700, and / or the HIPD 607 detect and coordinate one or more user inputs to launch a messaging application and prepare a response to a message received via the messaging application.

[0090] In some embodiments, the user 602 launches an application on the wrist wearable device 603, the AR device 700, and / or the HIPD 607 via user input, which causes the application to be launched on at least one device. For example, in the second AR system 600b, the user 602 performs a gesture associated with a command for launching a messaging application (represented by the messaging user interface 612); the wrist wearable device 603 detects the gesture; and based on determining that the user 602 is wearing the AR device 700, the AR device 700 presents the messaging user interface 612 of the messaging application. The AR device 700 can present the messaging user interface 612 to the user 602 through its display (e.g., as shown in the field of view 610 of the user 602). In some embodiments, the application is launched and can be run on the device (e.g., the wrist wearable device 603, the AR device 700, and / or the HIPD 607) that detects the user input to launch the application, and the device provides another device running data to cause the messaging application to be presented. For example, the wrist wearable device 603 can detect user input for launching a messaging application, launch and run the messaging application, and provide operation data to the AR device 700 and / or the HIPD 607 so that the messaging application is presented. Alternatively, the application can be launched and run on a device other than the device that detects the user input. For example, the wrist wearable device 603 can detect a gesture associated with launching a messaging application, and cause the HIPD 607 to run the messaging application and coordinate the presentation of the messaging application.

[0091] In addition, the user 602 can provide user input provided at the wrist wearable device 603, the AR device 700, and / or the HIPD 607 to continue and / or complete an operation initiated at another device. For example, after launching a messaging application via the wrist wearable device 603, and when the AR device 700 presents the messaging user interface 612, the user 602 can provide input at the HIPD 607 to prepare a response (e.g., as shown by a sliding gesture performed on the HIPD 607). The gesture of the user 602 performed on the HIPD 607 can be provided and / or displayed on another device. For example, the sliding gesture performed by the user 602 on the HIPD 607 is displayed on the virtual keyboard of the messaging user interface 612 displayed by the AR device 700.

[0092] In some embodiments, the wrist wearable device 603, the AR device 700, the HIPD 607, and / or other communication coupling devices may present one or more notifications to the user 602. The notification may be an indication of a new message, an incoming call, an application update, a status update, etc. The user 602 may select the notification via the wrist wearable device 603, the AR device 700, the HIPD 607, and cause an application or operation associated with the notification to be presented on at least one device. For example, the user 602 may receive a notification that a message is received at the wrist wearable device 603, the AR device 700, the HIPD 607, and / or other communication coupling devices, and provide user input at the wrist wearable device 603, the AR device 700, and / or the HIPD 607 to view the notification, and the device detecting the user input may cause the application associated with the notification to be launched and / or presented at the wrist wearable device 603, the AR device 700, and / or the HIPD 607.

[0093] Although the above example describes coordinated input for interacting with a messaging application, a person skilled in the art will understand upon reading this specification that user input can be coordinated to interact with any number of applications, including but not limited to gaming applications, social media applications, camera applications, web-based applications, financial applications, etc. For example, the AR device 700 can present gaming application data to the user 602, and the HIPD 607 can use a controller to provide input to the game. Similarly, the user 602 can use the wrist wearable device 603 to activate the camera of the AR device 700, and the user can use the wrist wearable device 603, the AR device 700, and / or the HIPD 607 to manipulate (e.g., zoom in or out, or apply a filter) image acquisition and acquire image data.

In some embodiments, the wearable accessory device and / or the intermediate processing device may be configured to couple with the AR device 700 via a coupling mechanism in electronic communication with a coupling sensor 724, wherein the coupling sensor 724 may detect when the electronic device becomes physically or electronically coupled with the AR device 700. In some embodiments, the AR device 700 may be configured to couple with a housing (e.g., a portion of the frame 704 or the temple arm 705), which may include one or more additional coupling mechanisms configured to couple with additional accessory devices. Fig. 7A The components shown in may be implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing components and / or application specific integrated circuits (ASICs).

[0101] The AR device 700 includes mechanical eyeglass components including a frame 704 configured to hold one or more lenses (e.g., one or two lenses 706-1 and 706-2). It will be appreciated by those of ordinary skill in the art that the AR device 700 may include additional mechanical components, such as hinges configured to allow portions of the frame 704 of the AR device 700 to fold and unfold, a bridge configured to span the gap between the lenses 706-1 and 706-2 and rest on the user's nose, a nose pad configured to rest on the bridge of the nose and provide support for the AR device 700, a temple cover configured to rest on the user's ear and provide additional support for the AR device 700, a temple arm 705 configured to extend from the hinge to the temple cover of the AR device 700, and the like. It will be further appreciated by those of ordinary skill in the art that some examples of the AR device 700 may not include any of the mechanical components described herein. For example, a smart contact lens configured to present AR to a user may not include any components of the AR device 700.

[0102] Lenses 706-1 and 706-2 can be separate displays or display devices (e.g., waveguides for projected representations). Lenses 706-1 and 706-2 can act together or independently to present an image or a series of images to a user. In some embodiments, lenses 706-1 and 706-2 can operate in conjunction with one or more display projector assemblies 707A and 707B to present image data to a user. Although AR device 700 includes two displays, embodiments of the present disclosure can be implemented in an AR device having a single near-eye display (NED) or more than two NEDs.

[0103] The AR device 700 includes electronic components, many of which will be described below with respect to FIG. Figure 7C Describe in more detail. Fig. 7A 700 , including sensors 723 - 1 , 723 - 2 , 723 - 3 , 723 - 4 , 723 - 5 , and 723 - 6 that may be distributed along a majority of the frame 704 of the AR device 700 . Figure 7C The AR device 700 also includes a left camera 739A and a right camera 739B located on different sides of the frame 704. And the eye-mounted device includes one or more processors 748A and 748B (e.g., an integrated microprocessor such as an ASIC) embedded in a portion of the frame 704.

[0104] Figure 7B-1 and Figure 7B-2An exemplary visual depiction of a VR device 710 (e.g., a head mounted display (HMD) 712, also referred to herein as an AR head mounted viewer, a head wearable device, a VR head mounted viewer, etc.) is shown. The HMD 712 includes a front body 714 and a frame 716 (e.g., a band or strap) shaped to fit around a user's head. In some embodiments, the front body 714 and / or the frame 716 include one or more electronic components for facilitating presentation of and / or interaction with an AR and / or VR system (e.g., a display, a processor (e.g., processor 748A-1), an IMU, a tracking transmitter or detector, or a sensor). In some embodiments, as Figure 7B-2 As shown, HMD 712 includes an output audio converter (e.g., audio converter 718). In some embodiments, as Figure 7B-2 As shown, one or more components such as one or more output audio transducers 718 and frame 716 (e.g., part or all of frame 716 and / or one or more output audio transducers 718) can be configured to be attached and detached from (e.g., removably attachable to) HMD 712. In some embodiments, coupling the removable component to HMD 712 enables the removable component to be in electronic communication with HMD 712. VR device 710 includes electronic components, many of which will be described below with respect to Figure 7C Describe in more detail.

[0105] Figure 7B-1 to Figure 7B-2 VR device 710 is also shown with one or more cameras, such as left camera 739A and right camera 739B, which can be similar to the left camera and right camera on frame 704 of AR device 700. In some embodiments, VR device 710 includes one or more additional cameras (e.g., cameras 739C and 739D), which can be configured to enhance the image data obtained by cameras 739A and 739B by providing more information. For example, camera 739C can be used to provide color information that cameras 739A and 739B cannot recognize. In some embodiments, one or more of cameras 739A to 739D can include an optional infrared (IR) cut filter that is configured to remove IR light received at the corresponding camera sensor.

[0106] The VR device 710 may include a housing 790 that stores one or more components of the VR device 710 and / or additional components of the VR device 710. The housing 790 may be a modular electronic device configured to couple with the VR device 710 (or AR device 700) and supplement and / or expand the capabilities of the VR device 710 (or AR device 700). For example, the housing 790 may include additional sensors, cameras, power supplies, and processors (e.g., processor 748A-2) that improve and / or increase the functionality of the VR device 710. Figure 7C Examples of different components included in housing 790 are described.

[0107] Alternatively or additionally, in some embodiments, a head wearable device such as a VR device 710 and / or an AR device 700 includes or is communicatively coupled to another external device (e.g., a pairing device), such as a HIPD 607 and / or an optional neckband. The optional neckband may be coupled to the head wearable device via one or more connectors (e.g., a wired connector or a wireless connector). The head wearable device and the neckband may operate independently without any wired or wireless connection between them. In some embodiments, components of the head wearable device and components of the neckband may be located on one or more additional peripheral devices, neckbands, or some combination thereof that are paired with the head wearable device. In addition, the neckband is intended to represent any suitable type or form of paired device. Therefore, the discussion of the neckband below may also be applied to various other paired devices, such as smart watches, smart phones, wristbands, other wearable devices, handheld controllers, tablet computers, or laptop computers.

[0108] In some cases, pairing an external device such as an intermediate processing device (e.g., HIPD 607, an optional neckband, and / or a wearable accessory device) with a head wearable device (e.g., AR device 700 and / or VR device 710) enables the head wearable device to achieve a form factor similar to a pair of glasses while still providing sufficient battery power and computing power to achieve expanded capabilities. Some or all of the battery power, computing resources, and / or additional features of the head wearable device can be provided by the paired device, or shared between the paired device and the head wearable device, thereby reducing the weight, thermal distribution, and form factor of the head wearable device as a whole, while still allowing the head wearable device to retain its desired functionality. For example, the intermediate processing device (e.g., HIPD 607) can allow components that would otherwise be included in the head wearable device to be included in the intermediate processing device (and / or wearable device or accessory device), thereby shifting the weight load from the user's head and neck to one or more other parts of the user's body. In some embodiments, the intermediate processing device has a large surface area over which to diffuse and disperse heat to the surrounding environment. Thus, the intermediate processing device may allow for greater battery power and computing power than a standalone head wearable device. Because the weight carried in the intermediate processing device is less intrusive to the user than the weight carried in the head wearable device, the user may tolerate wearing a lighter eye-mounted device and carrying or wearing a paired device for longer periods of time than the user would tolerate wearing a heavier eye-mounted device alone, thereby enabling the user to more fully integrate the AR environment into their daily activities.

[0109] In some embodiments, the intermediate processing device is communicatively coupled to the head wearable device and / or other devices. These other devices can provide certain functions (e.g., tracking, positioning, depth map construction, processing and / or storage) for the head wearable device. In some embodiments, the intermediate processing device includes a controller and a power supply. In some embodiments, the sensor of the intermediate processing device is configured to sense additional data in an electronic format (analog or digital) that can be shared with the head wearable device.

[0110] The controller of the intermediate processing device processes information generated by the intermediate processing device and / or sensors on the head wearable device. The intermediate processing device such as HIPD 607 can process information generated by one or more of its sensors and / or information provided by other communication coupling devices. For example, the head wearable device may include an IMU, and the intermediate processing device (neckband and / or HIPD 607) can calculate all inertial operations and spatial operations from the IMU located on the head wearable device. Additional examples of processing performed by communication coupling devices such as HIPD 607 are provided.

[0111] The AR system may include various types of visual feedback mechanisms. For example, the display device in the AR device 700 and / or the display device in the VR device 710 may include one or more liquid crystal displays (LCD), light emitting diodes (LED) displays, organic LED (OLED) displays, and / or any other suitable type of display screen. The AR system may include a single display screen for both eyes, or a display screen may be provided for each eye, which may provide additional flexibility for zoom adjustment or correction of refractive errors associated with user vision. Some AR systems also include an optical subsystem having one or more lenses (e.g., conventional concave or convex lenses, Fresnel lenses, or adjustable liquid lenses), through which the user can view the display screen. In addition to or instead of using a display screen, some AR systems include one or more projection systems. For example, the display device in the AR device 700 and / or the display device in the VR device 710 may include a micro-LED projector (e.g., using a waveguide) that projects light into the display device, such as a transparent combiner lens that allows ambient light to pass through. The display device may refract the projected light toward the user's pupil and may enable the user to view both the AR content and the real world simultaneously. The AR system may also be configured with any other suitable type or form of image projection system. As described above, some AR systems may substantially replace one or more sensory perceptions of the user's real world with a virtual experience, rather than combining artificial reality with actual reality.

[0112] Although the exemplary head wearable devices are described herein as AR device 700 and VR device 710, respectively, either or both of the exemplary head wearable devices described herein can be configured to present a fully immersive VR scene presented in substantially all of the user's field of view, and additionally or alternatively, present a more subtle augmented reality scene presented in a portion (less than all) of the user's field of view.

[0113] In some embodiments, the AR device 700 and / or the VR device 710 may include a tactile feedback system. The tactile feedback system can provide various types of skin feedback, including vibration, force, traction, shear, texture and / or temperature. The tactile feedback system can also provide various types of kinesthetic feedback, such as motion and compliance. Tactile feedback can be implemented using motors, piezoelectric actuators, fluid systems and / or various other types of feedback mechanisms. The tactile feedback system can be implemented independently of other AR devices, implemented in other AR devices, and / or in combination with other AR devices (e.g., wrist wearable devices that can be integrated into headwear, gloves, tights, handheld controllers, environmental devices (e.g., chairs or foot pads), and / or any other type of device or system (such as wrist wearable devices 603, HIPD 607, clothing based on smart textiles)) and / or other devices described herein.

[0114] Figure 7C A computing system 720 and an optional housing 790 are shown, each of which illustrates components that may be included in a head wearable device (e.g., AR device 700 and / or VR device 710). In some embodiments, more or fewer components may be included in the optional housing 790, depending on the practical constraints of the respective head wearable device described. Additionally or alternatively, the optional housing 790 may include additional components that expand and / or enhance the functionality of the head wearable device.

[0115] In some embodiments, computing system 720 and / or optional housing 790 may include one or more peripheral device interfaces 722A and 722B, one or more power systems 742A and 742B (including charging input 743, PMIC 744, and battery 745), one or more controllers 746A and 746B (including one or more haptic controllers 747), one or more processors 748A and 748B (as defined above, including any of those examples provided), and memory 750A and 750B, all of which may be in electronic communication with each other. For example, one or more processors 748A and / or 748B may be configured to execute instructions stored in memory 750A and / or 750B, which instructions may cause a controller in one or more controllers 746A and / or 746B to cause operations to be performed at one or more peripheral devices of peripheral device interfaces 722A and / or 722B. In some embodiments, each of the operations described may occur based on power provided by power systems 742A and / or 742B.

[0116] In some embodiments, the peripheral device interface 722A may include one or more devices configured as part of the computing system 720, many of which have been defined above. For example, the peripheral device interface may include one or more sensors 723A. Some exemplary sensors include: one or more coupling sensors 724, one or more acoustic sensors 725, one or more imaging sensors 726, one or more EMG sensors 727, one or more capacitive sensors 728, and / or one or more IMUs 729. In some embodiments, the sensor 723A also includes a depth sensor 767, a light sensor 768, and / or any other type of sensor defined above or described with respect to any other embodiment discussed herein.

[0117] In some embodiments, the peripheral device interface may include one or more additional peripheral devices, including one or more NFC devices 730, one or more GPS devices 731, one or more LTE devices 732, one or more Wi-Fi and / or Bluetooth (WiFi / BT) devices 733, one or more buttons 734 (e.g., including slidable or otherwise adjustable buttons), one or more displays 735A, one or more speakers 736A, one or more microphones 737A, one or more cameras 738A (e.g., including a first camera 739-1 to an nth camera 739-n similar to a left camera 739A and / or a right camera 739B), one or more tactile devices 740, and / or any other type of peripheral device defined above or described with respect to any other embodiments discussed herein.

[0118] The head wearable device may include various types of visual feedback mechanisms (e.g., presentation devices). For example, the display device in the AR device 700 and / or the display device in the VR device 710 may include one or more liquid crystal displays (LCDs), light emitting diode (LED) displays, organic LED (OLED) displays, micro-LEDs, and / or any other suitable type of display screen. The head wearable device may include a single display screen (e.g., configured to be viewed by both eyes) and / or may provide a separate display screen for each eye, which may provide additional flexibility for zoom adjustment or correction of refractive errors associated with user vision. Some embodiments of the head wearable device also include an optical subsystem having one or more lenses (e.g., conventional concave or convex lenses, Fresnel lenses, or adjustable liquid lenses) through which the user can view the display screen. For example, each display 735A may be coupled to each of the lenses 706-1 and 706-2 of the AR device 700. The display 735A coupled to each of the lenses 706-1 and 706-2 may act together or independently to present an image or a series of images to the user. In some embodiments, the AR device 700 and / or VR device 710 includes a single display 735A (e.g., a near-eye display) or more than two displays 735A.

[0119] In some embodiments, the first group of one or more displays 735A can be used to present an augmented reality environment, and the second group of one or more displays 735A can be used to present a VR environment. In some embodiments, one or more waveguides are used in conjunction with presenting AR content to a user of the AR device 700 and / or VR device 710 (e.g., as a means of delivering light from a display projector assembly and / or one or more displays 735A to the user's eyes). In some embodiments, one or more waveguides are fully or partially integrated into the AR device 700 and / or VR device 710. In addition to or instead of using a display screen, some AR systems may include one or more projection systems. For example, a display device in the AR device 700 and / or a display device in the VR device 710 may include (e.g., using a waveguide) a micro-LED projector that projects light into the display device, such as a transparent combiner lens that allows ambient light to pass through. The display device can refract the projected light toward the user's pupil, and can enable the user to view both AR content and the real world at the same time. The head wearable device may also be configured with any other suitable type or form of image projection system. In some embodiments, additionally or alternatively, one or more waveguides are provided for one or more displays 735A.

[0120] In some embodiments of the head wearable device, ambient light and / or a real-world real-time view (e.g., a real-time feed of the surrounding environment that a user would normally see) can pass through a display element of a corresponding head wearable device that presents aspects of the AR system. In some embodiments, the ambient light and / or real-world real-time view can pass through a portion (not all) of the AR environment presented within the user's field of view (e.g., a portion of the AR environment is co-located with physical objects in the user's real-world environment that is within a specified boundary (e.g., a guardian boundary) configured to be used by the user when interacting with the AR environment). For example, a visual user interface element (e.g., a notification user interface element) can be presented at the head wearable device, and a certain amount of ambient light and / or real-world real-time view (e.g., 15% to 50% of the ambient light and / or real-world real-time view) can pass through the user interface element so that the user can distinguish at least a portion of the physical environment on which the user interface element is displayed.

[0121] The head wearable device may include one or more external displays 735A for presenting information to the user. For example, the external display 735A may be used to display the current battery level, network activity (e.g., connected, disconnected), current activity (e.g., playing games, talking, meeting, or watching movies), and / or other relevant information. In some embodiments, the external display 735A may be used to communicate with other elements. For example, a user of the head wearable device may cause the external display 735A to present a "Do Not Disturb" notification. The user may also use the external display 735A to share any information collected by one or more components of the peripheral device interface 722A and / or generated by the head wearable device (e.g., during the operation and / or execution of one or more applications).

[0122] The memory 750A may include instructions and / or data that may be executed by one or more processors 748A (and / or processor 748B of housing 790) and / or a memory controller of one or more controllers 746A (and / or controller 746B of housing 790). The memory 750A may include one or more operating systems 751, one or more applications 752, one or more communication interface modules 753A, one or more graphics modules 754A, one or more AR processing modules 755A, and / or any other type of module or component defined above or described with respect to any other embodiment discussed herein.

[0123] The data 760 stored in the memory 750A may be used in conjunction with one or more of the applications and / or programs discussed above. The data 760 may include profile data 761, sensor data 762, media content data 763, AR application data 764, and / or any other type of data defined above or described with respect to any other embodiment discussed herein.

[0124] In some embodiments, the controller 746A of the head wearable device processes information generated by the sensor 723A on the head wearable device and / or another component of the head wearable device and / or another component communicatively coupled to the head wearable device (e.g., a component of the housing 790, such as a component of the peripheral device interface 722B). For example, the controller 746A can process information from the acoustic sensor 725 and / or the imaging sensor 726. For each detected sound, the controller 746A can perform a Direction-Of-Arrival (DOA) estimate to estimate the direction from which the detected sound arrived at the head wearable device. When one or more acoustic sensors 725 detect a sound, the controller 746A can populate an audio data set with information (e.g., represented by sensor data 762).

[0125] In some embodiments, a physical electronic connector can transmit information between a head wearable device and another electronic device, and / or between one or more processors 748A and a controller 746A of a head wearable device. This information can be in the form of optical data, electrical data, wireless data, or any other transmittable form of data. Moving the processing of information generated by the head wearable device to an intermediate processing device can reduce weight and heat in the eye-mounted device, making the eye-mounted device more comfortable and safer for the user. In some embodiments, an optional accessory device (e.g., an electronic neckband or HIPD 607) is coupled to the head wearable device via one or more connectors. The connector can be a wired connector or a wireless connector, and can include electronic components and / or non-electronic (e.g., structural) components. In some embodiments, the head wearable device and the accessory device can operate independently without any wired or wireless connection between them.

[0126] The head wearable device may include various types of computer vision components and subsystems. For example, the AR device 700 and / or the VR device 710 may include one or more optical sensors, such as a two-dimensional (2D) camera or a three-dimensional (3D) camera, a ToF depth sensor, a single beam or scanning laser rangefinder, a 3D laser radar (LiDAR) sensor, and / or any other suitable type or form of optical sensor. The head wearable device may process data from one or more of these sensors to identify the user's location and / or various aspects of the user's real-world physical environment, including the location of real-world objects in the real-world physical environment. In some embodiments, the methods described herein are used to map the real world, provide users with context about the real-world environment, and / or generate interactive virtual objects (which may be replicas or digital twins of real-world objects that can interact with the AR environment), as well as various other functions. For example, Figure 7B-1 and Figure 7B-2 A VR device 710 is shown having cameras 739A to 739D that can be used to provide depth information for creating a voxel field and a two-dimensional (2D) grid to provide object information to the user for collision avoidance.

[0127] The optional housing 790 may include components similar to those described above with respect to the computing system 720. For example, the optional housing 790 may include a corresponding peripheral device interface 722B, which includes more or fewer components than those described above with respect to the peripheral device interface 722A. As described above, the components of the optional housing 790 may be used to enhance and / or expand the functionality of the head wearable device. For example, the optional housing 790 may include corresponding sensors 723B, speakers 736B, displays 735B, microphones 737B, cameras 738B, and / or other components for collecting and / or presenting data. Similarly, the optional housing 790 may include one or more processors 748B, controllers 746B, and / or memory 750B (including corresponding communication interface modules 753B, one or more graphics modules 754B, and one or more AR processing modules 755B), which may be used alone and / or in combination with components of the computing system 720.

[0128] The above 7A to 7C The technology described in the can be used with different head wearable devices. In some embodiments, the head wearable device (e.g., AR device 700 and / or VR device 710) can be used in combination with one or more wearable devices such as wrist wearable device 603 (or components of the wrist wearable device) and HIPD 607.

[0129] FIG. 8A to FIG. 8B A portable charging case 800 is shown including an LED ring 802 integrated with a buckle 804 of the portable charging case 800 according to some embodiments. Fig. 8A The portable charging case 800 is shown in a closed position 806, wherein the LED ring 802 is visible to indicate the charging status of the portable charging case 800 and / or a pair of smart glasses (not shown) housed within the portable charging case 800. In some embodiments, the clasp 804 is configured to fully or partially hold the lid portion 808 closed. In some embodiments, one or more magnets can be configured to fully or partially hold the lid portion closed. Fig. 8A Also shown is the LED ring 802 without illuminating the center portion 810, which will be referred to as Fig. 9 Further details are described. In some embodiments, the clasp is also magnetic and couples with the LED ring 802. In some embodiments, the clasp is a button and clips in place.

[0130] Figure 8B The portable charging case 800 is shown in an open position 812, wherein the LED ring 802 is still visible to the user and still provides a reference to the Fig. 8A Same functions as described above. Figure 8B As shown, additional magnets 814A and 814B can be placed on the portable charging box 800 to additionally secure the charging box when the charging box is in a closed position. In some embodiments, the position of the additional magnets 814A and 814B can vary with the number of magnets. For example, in some embodiments, one or more magnets 816 surround the LED ring 802, and in some cases, one or more magnets 816 are multiple magnets with different polarities to adjust the force required to loosen the fastener. In this example, the fastener 804 can be made of a ferrous material that is configured to attach to one or more magnets 816.

[0131] Fig. 9 According to some embodiments Fig. 8A and Figure 8BA cross-sectional view of an LED ring is shown. As shown in the first pane 900, a buckle portion including an LED ring is shown. As will be clear, only the ring portion (also referred to as a light ring) 902 emits light, while the center portion and the side portions do not emit light, thereby providing a light ring to the user. In some embodiments, the portable charging box 800 is configured to have different colors while still maintaining the same light ring without light bleeding into the surrounding area 903. In some embodiments, light leakage is reduced by adding titanium dioxide to the surrounding area to increase opacity. This addition of titanium dioxide is useful for surrounding areas with lighter colors (e.g., brown plastic). In some embodiments, the material of the surrounding area is composed of polycarbonate and ABS and at least titanium dioxide accounting for 0.1% to 5% of the total mass of the material. In some embodiments, excessive titanium dioxide can cause aesthetic problems on the surface, and therefore, adding more than 5% titanium dioxide to the material is not preferred.

[0132] Fig. 9 A cross-sectional view 908 of the LED ring (including the LED ring) is shown in the second pane, and different materials are also shown to display the LED ring to the user. For example, the cross-sectional view shows three areas (e.g., continuous side areas 904A and 904B and center portion 906 (these portions correspond to surrounding area 903) in which light from the LED is blocked to produce ring portion 902) that include titanium dioxide material to reduce light leakage. Although titanium dioxide is required for lighter colors, it is not necessarily required for darker colors (e.g., black). The cross-sectional view 908 also shows a location (also referred to as a cavity) 910 where one or more LEDs will be located. Fig. 9 Also shown is providing a first dose of material to the surrounding area 903 and then providing a second dose of material to create a ring portion 902 including locations 910 for LEDs, thereby creating a light pipe.

[0133] Fig.10 The fixing positions on a pair of smart glasses according to some embodiments are shown, so that smart glasses of other designs can be docked with a portable charging case while maintaining these points. Fig.10 As shown, in one example, certain parts of a pair of smart glasses remain fixed, but the shape and size of non-fixed positions are allowed to vary, thereby forming a modular smart glasses platform that allows the creation of multiple smart glasses with different shapes that can all be connected to a single portable charging box. By allowing commonality between certain parts (e.g., having the same portable smart charging box), having a modular platform reduces the number of stock keeping units (SKUs) required for the product.

[0134] Fig.10An example location is shown where a pair of smart glasses 1000 has fixed areas 1002, 1004, and 1006 that allow the pair of smart glasses to interface with a portable charging case (e.g., couple and receive a charge). In some embodiments, these fixed areas are located around the bridge of the nose 1008 of a pair of smart glasses 1000, as in this example, which is where the portable smart glasses are configured to receive a charge and are secured within a portable charging case. This is shown in the enlarged area 1010, which shows how the pair of smart glasses 1000 is coupled to a location 1012 within a portable charging case 1014. In some embodiments, these locations can be different depending on where the pair of smart glasses 1000 receives a charge and / or how the pair of smart glasses are configured to be secured within a portable charging case 1014.

[0145] (D8) In some embodiments of D7, a common fixing location is located on each nose pad and nose bridge. For example, Fig.10 A pair of smart glasses 1000 is shown with example locations of fixed areas 1002, 1004, and 1006 that allow the pair of smart glasses to interface with (e.g., couple to and receive a charge from) a portable charging case.

[0146] (D9) In some embodiments of any one of D1 to D8, the light ring is produced using a first dose of colored material and a second dose of translucent material. For example, Fig. 9 It is shown providing a first dose of material to a surrounding area 903 and then providing a second dose of material to produce a ring portion 902 that includes locations 910 for LEDs.

[0147] (D10) In some embodiments of D9, titanium dioxide is added to the first dose of colored material to increase the opacity of the material to prevent light from leaking from the lamp into the first dose of colored material. In some embodiments, titanium dioxide is only required for lighter colors (such as brown), while black does not require titanium dioxide. Fig. 9 A surrounding area 903 is shown having a different color than the light ring 902 .

[0148] (D11) In some embodiments of D1 to D10, titanium dioxide comprises 0.1% to 5% by volume (or mass) of the first dose material. In some embodiments, titanium dioxide comprises 3% to 5% by volume or mass of the first dose material. In some embodiments, titanium dioxide comprises 0.3% to 0.5% by volume or mass of the first dose material.

[0149] (D12) In some embodiments of any one of D1 to D11, the light ring is generated by a light pipe illuminated by a multi-color LED. The light pipe is made of a second material and allows one or more LEDs to be inserted into the light pipe. For example, Fig. 9 A cavity 910 configured to receive an LED is shown.

[0150] (D13) According to the portable charging case of the embodiment, the color of the buckle matches the color of the portable charging case. For example, a brown charging case will have a first dose of material that is also brown, or a black charging case will have a first dose of material that is also black.
