Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63 / 339,131, filed on May 6, 2022. Background Art

[0003] Wearable electronic devices typically have a very limited amount of space for electronic and mechanical components. Often, these components may be positioned in non-optimal locations, including locations that are prone to "desense" or signal quality loss. For example, a wearable electronic device placed on the wearer's head may lose Radio Frequency (RF) energy absorbed by the user's head. Other body parts may similarly attenuate or degrade wireless signal quality. If antennas or other components are placed in close proximity to the user's head or other body parts, this may result in reduced antenna efficiency. For example, in a pair of virtual reality goggles, if one or more antennas are placed in close proximity to the user's ears or the user's temporal region, the user's head may absorb a significant amount of incoming or outgoing signals.

[0004] Furthermore, many wearable electronic devices can implement multiple antennas to increase data throughput. For example, dual antennas can be used in series in a multiple input multiple output (MIMO) manner to transmit data in a more reliable manner or at a higher throughput. However, in this case, if the dual antennas are placed too close to each other, the antennas may suffer from poor isolation relative to each other, resulting in poor MIMO performance. In addition to the degraded MIMO performance, this lack of isolation may also reduce antenna efficiency, thereby increasing the amount of power required to operate the antenna. This in turn may reduce the battery life in the wearable device and may increase the heat generated by the wearable device. This increase in operating power may also increase the amount of RF energy absorbed by the user, and specifically the amount of RF energy absorbed by the user's head, which is limited by regulatory exposure levels.

[0046] The present disclosure generally relates to the manufacture, design, assembly, and implementation of antennas for wearable electronic devices.

[0047] As will be explained in more detail below, embodiments of the present disclosure may strategically position antennas physically separated from other electronic and mechanical components, and may also be positioned away from the user's body. In some embodiments, the antenna may be placed on a lower edge portion of a wearable electronic device. For example, in a head-mounted virtual reality display or on augmented reality glasses, one or more antennas may be placed on a lower edge near the user's cheek. In at least some embodiments, the lower edge area may be substantially free of cameras, chipsets, sensors, speakers, or other components. In addition, the antenna may be pushed forward on the lower edge away from the user's cheek. In some cases, an overmold (e.g., made of plastic) may be formed on the antenna so that the antenna does not contact the user's skin or is not in direct contact with the user.

[0048] In the embodiments described below, substantially any type of antenna architecture can be used. For example, antennas placed on the bottom edge of artificial reality glasses, or on the bottom of a virtual reality head-mounted device (HMD), or on the bottom of other types of eye-wearing devices may include loop antennas, monopole antennas, dipole antennas, slot antennas, or other types of antennas. These antennas can be connected to a system ground, which, at least in some cases, can be a metal frame or support structure to which various wearable device components are attached. In some cases, the antenna can be clamped to a portion of the metal frame, while in other cases, the antenna can be integrated into the frame. In addition, the antenna can be connected to various radio devices (e.g., WiFi radio devices), processors, controllers, or other chipsets within the wearable electronic device. In the case of using multiple antennas, the lengths of the electrical connections to the radio device or controller can be equal or substantially equal. This may help ensure that each antenna operates at the same or similar efficiency level. This may be beneficial when operating in MIMO mode, in which the signals from each antenna are combined to improve the efficiency of transmission or reception. The following will refer to Figures 1 to 3. Fig.19B Each of these embodiments is described in further detail.

[0049] Features from any of the embodiments described herein may be used in combination with each other according to the general principles described herein. These and other embodiments, features and advantages will be more fully understood after reading the following detailed description in conjunction with the accompanying drawings and claims.

[0050] Figures 1A to 1JVarious embodiments of wearable electronic devices that can implement the antenna structure described herein are shown. As described above, placing antennas (including WiFi antennas, Bluetooth antennas, global positioning system (GPS) antennas, cellular antennas, near field communication (NFC) antennas or other types of antennas) near the user's ears or temporal parts (e.g., on the temple arms of the device) may result in higher than desired RF absorption rates in the user's head. Since this area is usually also filled with other noisy electronic components, the risk of receiver sensitivity deterioration is also higher. Placing the antenna in the top portion of the wearable device may also be problematic. As used herein, the "top portion" of a wearable electronic device may refer to the brow bar portion that is located near the bridge of the user's nose and extends along their eyebrows and lower jaw. The top portion may include a plurality of different electronic components, including cameras, controllers, depth sensors, infrared sensors, inertial motion units (IMU), radio devices or other components. Therefore, antennas may not be installed in these locations, or if antennas are placed in these locations, the antennas may be too close to other components, causing interference to these components. This can result in degraded antenna sensitivity, heat dissipation issues, and potential interference with other components.

[0051] The embodiments described herein may be configured to position antennas, radios, or antenna / radio combinations in locations with few or no other components, at least partially removed from the user's head, and spaced apart from each other, thereby providing the two (or more) antennas with the isolation needed to operate effectively in MIMO mode. For example, Figure 1A The virtual reality (VR) head mounted device 100A of FIG. 1 shows an embodiment of a right antenna 101A and a left antenna 103A each positioned in a lower portion of the VR head mounted device 100A. The term "lower portion" as used herein may refer to the lower half of the device when the device is worn by a user above the user's eyes. Thus, the lower portion includes a bottom edge portion that rests below the user's eyes and curves upward, over, and downward along the user's nose.

[0052] The VR head-mounted device 100A may also include a radio device 102A positioned in the top portion of the VR head-mounted device 100A. The right antenna 101A and the left antenna 103A may each be electrically connected to the radio device 102A via metal traces or wires. Although the radio device is shown as being positioned in the middle of the upper portion of the VR head-mounted device 100A (i.e., between the eyes of the user), it can be appreciated that the radio device 102A can be positioned at substantially any position along the upper portion of the VR head-mounted device. In addition, it should be understood that the term "radio device" used herein may include multiple parts of an antenna feed structure, including amplifiers, tuners, impedance matching circuits, transmitters, receivers, filters, or other electronic components for sending or receiving wireless signals. In some cases, the radio device 102A may be one of many radio devices within the VR head-mounted device 100A, which may be positioned on the top portion or bottom portion of the head-mounted device. Further, at least in some cases, the radio device 102A may be positioned next to a processor or controller. The processor or controller may be configured to send signals to one or more radios for transmission, or may interpret or process received signals from radio 102A.

[0053] Figure 1B An embodiment of a pair of aviation goggles 100B is shown, which includes a right antenna 101B, a left antenna 103B and at least one radio device 102B, wherein the right antenna 101B and the left antenna 103B are electrically connected to the at least one radio device 102B. Figure 1AThe VR head mounted device 100A shown can position the right antenna 101B and the left antenna 103B on the bottom edge portion of the aviation goggles 100B. The bottom edge portion can be away from other electronic components, including cameras, depth sensors, processors, IMUs or other components. This positioning on the bottom edge of the goggles can provide sufficient isolation for each of the antennas 101B / 103B to operate properly in MIMO mode, or in isolation mode when necessary, in which one of the antennas operates on its own (for example, when one of the antennas is not operating or is blocked by the user's hand). In some embodiments, the right antenna 101B and the left antenna 103B can each be electrically connected separately to one or more radio devices (e.g., 102B) via traces or wires. In fact, it should be understood that in the embodiments of the present invention, each side of the wearable device can have a single antenna or can have multiple antennas, and each of these antennas can be connected to the same radio device or a different radio device. Furthermore, although the radio 102B is shown as being positioned in the center of the aviation goggle 100B, the radio 102B or other radios may be positioned on the bottom edge, in the eye bridge, in the headband, or in substantially any other location within the wearable electronic device.

[0054] Figure 1C A ski mask 100C is shown including a right antenna 101C, a left antenna 103C and at least one radio device 102C. Figure 1C In the illustrated embodiment, the right and left antennas (101C / 103C) of the ski mask 100C can be positioned in the right and left lower halves of the ski mask, respectively. In some cases, the right and left antennas 101C, 103C can be embedded in at least a portion of the frame of the ski mask. The wires or traces connecting the right and left antennas 101C, 103C to one or more radio devices can be routed along the outer edge of the ski mask 100C. In this way, the wires extending along the outer edge may not be visible to the user and may not obstruct the user's view.

[0055] Figure 1DA pair of artificial reality glasses 100D is shown, which may include a right antenna 101D and a left antenna 103D and one or more radio devices 102D. In some embodiments, the one or more radio devices 102D can be positioned on a main board (e.g., a PCB) that is at least partially disposed on a nose bridge of the artificial reality glasses 100D. The right antenna 101D and the left antenna 103D can be positioned on a bottom edge portion of the artificial reality glasses 100D, away from other electronic components or mechanical components. In addition, at least in some cases, the right antenna 101D and the left antenna 103D can be moved forward away from the user's face along the z-axis and can be positioned on the outer edge of the bottom edge (e.g., FIG. 4A to FIG. 4D ). This location can be further away from the user's cheek so that less RF radiation is absorbed by the wearer's head.

[0056] Furthermore, the right antenna 101D and the left antenna 103D can be moved rightward or leftward along the x-axis within the bottom edge portion of the artificial reality glasses 100D. Thus, at least in some cases, the right antenna 101D and the left antenna 103D can be moved toward the inner portion of the glasses (e.g., toward the user's nose) so that the antennas are at least partially placed on the inner curvature of the bottom edge portion of the artificial reality glasses 100D (e.g., toward the user's nose). 9A to 9D In addition, in other cases, the right antenna 101D and the left antenna 103D can be moved toward the outer portion of the glasses (e.g., toward the outer edges of the wearer's eyes) so that the antennas are at least partially placed on the outer curvature of the bottom edge portion of the artificial reality glasses 100D (e.g., FIG. 10A to FIG. 10D further shown).

[0057] Figure 1E to Figure 1J Various other embodiments of wearable devices 100E to 100J in which antennas may be integrated are shown. For example, Figure 1E A pair of night vision goggles 100E is shown, which may include a right antenna 101E, a left antenna 103E, and one or more radio devices 102E. As in the above example, the right antenna 101E and the left antenna 103E may be positioned on the bottom edge portion of the night vision goggles 100E. Figure 1F 3D goggles 100F, Figure 1G Safety goggles 100G, Figure 1H Protective goggles 100H, Fig. 1I Sports Goggles 100I and Figure 1JThis may also be the case with the sports eye wearable device 100J. Each of these wearable devices can have a right antenna 101E to 101J, a left antenna 103E to 103J, and one or more radio devices 102E to 102J. These antennas can be placed in the lower edge portion of these wearable devices, away from other potentially interfering electronic components, and away from the wearer's temples or ears, or other parts of the wearer's head that may absorb larger amounts of RF radiation. In each of these wearable devices 100E to 100J, the wires or traces connecting the antenna to the one or more radio devices can extend along an internal portion of the wearable device, or can extend along an external portion of the wearable device, such as FIG. 6A to FIG. 6D As shown in the embodiment of the present invention.

[0058] FIG. 2A to FIG. 2J Shows Figures 1A to 1J The same wearable device embodiment shown, but without the outer cover or housing. Thus, the internal electronic and mechanical components can be seen. For example, Figure 2A Embodiments of a virtual reality head mounted display 200A having a plurality of different internal components are included. These components may be electronic components, mechanical components, structural components, or other types of components. For example, the virtual reality head mounted display 200A may include speakers placed near the user's ears. The virtual reality head mounted display 200A may also include cameras, processors, radios, IMUs, microphones, or other components. The number of components, the size of these components, and the placement of these components may vary. FIG. 2B to FIG. 2J However, it should be understood that each of these wearable devices 200A to 200J may include different types of components placed in different locations.

[0059] In some embodiments, Figure 2A As shown, the virtual reality head-mounted display 200A may include a right antenna 201A and a left antenna 203A. The right antenna 201A (or the right antennas 201B to 201J) may be connected to a radio 202A (e.g., a WiFi radio) via a wire or trace. Similarly, the left antenna 203A (or the left antennas 203B to 203J) may be connected to the radio 202A (or the corresponding radios 202B to 202J) via a separate wire or trace. In this embodiment, the traces may be routed around the outside of the wearable device so as not to obstruct the wearer's line of sight. However, in some cases, one or more of these traces may pass through an internal portion of the wearable device (e.g., in Figure 2D The wiring is performed in the artificial reality glasses 200D).

[0060] By placing the right antenna and the left antenna in the bottom portion of the wearable device, the embodiments of the present invention can avoid or reduce interference from other electronic components or mechanical components, the antennas can be placed farther away from the user's head, resulting in higher antenna efficiency and increased antenna throughput because these embodiments can provide high isolation between the antennas due to the physical distance between the antennas. Further, since each antenna can be located at a short and symmetrical distance from the radio device 202A, placing the antennas on the bottom portion of the wearable device can additionally improve efficiency by providing similar levels of operating performance from each antenna. In addition, the wearable device 200A can implement an overmold that rests directly against the wearer's cheek. The overmold can be located between the antenna and the user's cheek. The overmold can be made of plastic or other RF transparent material and can ensure that the antenna has a buffer between the antenna and the user's skin. The following will be combined with FIG. 3A to FIG. 3D Explain this further.

[0061] FIG. 2B to FIG. 2J The other wearable devices (i.e., wearable devices 200B to 200J) may each include a speaker, a camera, a processor, a radio device (e.g., 202B to 202J), an IMU, a microphone, or other internal components. These wearable devices may also include hinges, clips, frames, or other structural elements or other components not shown. In a similar manner, each of these wearable devices 200B to 200J may include a right antenna 201B to 201J and a left antenna 203B to 203J, each of which may be electrically connected to the radio device 202B to 202J via a wire or trace. In each of these cases, the wire or trace may be routed in a manner that provides a trace of similar length for each antenna.

[0062] In addition, in each of these embodiments, substantially any type of antenna architecture may be implemented, including monopole antennas, dipole antennas, loop antennas, slot antennas, or other types of antennas. Further, although generally described herein as having two antennas, each wearable device 200A to 200J may include substantially any number of antennas and substantially any number of radio devices. In some embodiments, for example, both a WiFi antenna and a Bluetooth antenna may be placed in the bottom edge portion of the wearable device, or a WiFi antenna, a Bluetooth antenna, and a cellular antenna, or other combinations of antennas may be placed in the bottom edge portion of the wearable device. In this case, the antennas may be sufficiently spaced apart from each other along the bottom edge portion to avoid or at least reduce interference caused by other antennas or by traces leading to the corresponding WiFi, Bluetooth, cellular, or other radio devices.

[0063] FIG. 3A to FIG. 3DEmbodiments of antenna architectures 300A to 300D are shown that may include various components. FIG. 3A to FIG. 3D Although the metal trace material 310A to 310D is arranged in a particular manner, it should be recognized that the metal trace material for the antenna (e.g., 310A to 310D) can be arranged in other configurations and can include more or less trace material. In some cases, the metal trace material 310A to 310D can be arranged as a loop for a loop antenna. In other cases, the metal trace material 310A to 310D can be arranged in a monopole or dipole manner for a monopole antenna or a dipole antenna, or can be arranged as a slot for a slot antenna. In addition, the overmold portion 308A to 308D can include more or less material and can be arranged in different shapes and arranged in different positions. In different embodiments, the ground clips 303A to 303D, the cables 302A to 302D, the overmolds 306A to 306D, and other components can also be moved to different positions.

[0064] For example, different types of wearable devices (e.g. Figures 1A to 1J 100A to 100J) may have different sizes, shapes, components, and other constraints. Therefore, the components of the antenna architectures 300A to 300D may be changed to accommodate these constraints. For example, Figure 3A The virtual reality head mounted device 300A may include a frame portion 301A. Figure 3A The visible section shown in shows the lower half of the right side of the virtual reality HMD. The virtual reality HMD may include an antenna architecture with an antenna 310A, whose metal trace may begin at point 305A. Matching components 304A and other antenna feed components may be connected to antenna trace 305A. A ground clip 303A, ground pin, or other grounding mechanism may be implemented to ground the antenna 310A to the frame 301A.

[0065] Signals received by or transmitted to the antenna 310A may be communicated via a wire or cable 302A. The cable 302A may be electrically connected to the antenna 310A via clips or pins 302A to 302D, and may transmit the signal to one or more radio devices (e.g., positioned in the bridge of the nose of the wearable device). The VR headset 300A may also include a molded portion 306A, which may be injection molded or otherwise formed to provide support for the metal traces of the antenna 310A. For example, the molded portion 306A may provide support for a ring shape or a dipole shape, etc. The molded portion 306A may be connected to the overmolded portion 308A via a bonding member 307A. The bonding member 307A may be formed using glue, fasteners (e.g., screws), clips, or some other type of bonding member. The overmolded portion 308A may provide a separation layer between the antenna 310A and the user's head. For example, as Figure 3A As shown, the overmold portion 308A can rest on the user's cheek, thereby raising the antenna from the user's skin. The overmold can be made using RF transparent materials so as not to interfere with the transmission or reception of the antenna 310A.

[0066] Figure 3B Sports goggles 300B, Figure 3C The sports eye wear device 300C and Figure 3D The artificial reality glasses 300D can each include similar components, including frames 301B to 301D and antennas 310B to 310D starting at 305B to 305D. Antennas 310B to 310D can be formed on molded portions 306B to 306D, which are themselves bonded (e.g., bonded via bonding pieces 307B to 307D) to overmolded portions 308B to 308D. These wearable devices can also include grounding clips 303B to 303D attached to at least a portion of the frames 301B to 301D or other grounding structures, as well as antenna impedance matching components 304B to 304D and cables 302B to 302D that transmit signals to and from the antennas 310B to 310D. As will be further shown below, antennas 310B-310D may be moved to different locations within the bottom edge portion of the wearable device.

[0067] In this general location in the bottom edge portion of the wearable device, the antennas can be positioned away from other device components and can be isolated from each other by being placed on the right or left side of the wearable device. This isolation can increase the efficiency of each antenna and can also increase the data throughput of the device. In addition, at least in some cases, one or more antennas on the left side can be FIG. 3A to FIG. 3DMirror images of one or more antennas on the right side shown. Because the antennas are mirror images, cables 302A to 302D can extend along an interior portion of the wearable device and can extend similar (or the same) lengths. This similarity in cable lengths can ensure that each antenna has a similar (high) level of performance. If for some reason the performance of one of these antennas begins to degrade (e.g., due to occlusion by a user's hand or one of his fingers), one or more other antennas on the device can be used instead, at least for a period of time.

[0068] FIG. 4A to FIG. 4D A bottom-up stereogram of different types of eyewear devices that can be used as wearable electronic devices is shown. In fact, any of the eyewear devices described herein may include an artificial reality component or a virtual reality component that presents artificial images or virtual images to the user's eyes. For example, Figure 4A The virtual reality head mounted device 400A may include a display component that presents images to the eyes of a user (e.g., user 405A). The virtual reality head mounted device 400A may communicate with an external computer system or other electronic device via one or more antennas (including a left antenna 402A). The left antenna 402A may be placed in a bottom edge portion 407A of the virtual reality head mounted device 400A. In at least some embodiments, the top portion 406A of the virtual reality head mounted device 400A may include other electronic components and / or mechanical components, such as Figure 2A 405A. These components can be secured to a frame 401A of the virtual reality head mounted device 400A. The left antenna 402A can include antenna feed components including a grounding clip 403A that grounds the antenna 402A to a metal portion 404A that can be part of a metal frame or subframe. In this embodiment, the left antenna 402A is depicted as being positioned toward the front of the virtual reality head mounted device 400A. This can set a distance between the cheek of the user 405A and the antenna 402A. This distance can improve the operating efficiency of the antenna.

[0069] FIG. 4B to FIG. 4D Other embodiments of eye-wearable devices that can be used as wearable electronic devices are shown, including Figure 4B Sports goggles 400B, Figure 4C Sports eye wear device 400C or Figure 4DArtificial reality glasses 400D. Each of these devices 400B to 400D may include a top portion 406B to 406D or a "brow bar" portion, a bottom portion 407B to 407D or a "bottom edge" portion, a frame 401B to 401D, a left antenna 402B to 402D, a ground clip 403B to 403D, a metal portion 404B to 404D, and an associated wearer 405B to 405D of the device. In some cases, as will be further described below, the left antenna 402B to 402D can be moved along the z-axis to be closer to the user's cheek, or can be moved inwardly toward the bridge of the nose of the device along the x-axis, or can be moved outwardly along the outer edge of the device along the x-axis. In some cases, the antenna can additionally or alternatively be moved upward along the y-axis, so that the antenna moves upward along the inner curve of the device toward the bridge of the nose, or moves upward along the outer curve of the device toward the outer edge of the device. Moving the antenna to a different location may provide less interference from other components, may change the length of the cable connecting the antenna to the radio, may provide additional distance between the left and right antennas, resulting in greater isolation and higher operating efficiency, and / or may provide other operational changes in how the antennas work individually or in conjunction with each other. 7A to 10D These concepts are further explained.

[0070] FIG. 5A to FIG. 5D Eye-wearable device embodiments are shown in which different types of antenna architectures are implemented. FIG. 5A to FIG. 5D The wearable electronic devices 500A to 500D may include Figures 4A to 4D , including antennas 502A to 502D, grounding clips 503A to 503D, metal portions 504A to 504D to which the antennas are grounded, frames 501A to 501D, top portions 506A to 506D, and bottom edge portions 507A to 507D. Each of the wearable devices 500A to 500D can be worn by a user 505A to 505D. The antennas on the various devices can be different in different embodiments. For example, Figure 5A The virtual reality head mounted device 500A may include a monopole antenna, Figure 5B The sports goggles 500B may include a dipole antenna, Figure 5C The sports eyewear device 500C may include a loop antenna, Figure 5DThe artificial reality glasses 500D may include a slot antenna. These are merely examples, and it should be understood that any wearable device may include any type of antenna architecture. However, these embodiments show that different antenna architectures may be implemented in different types of wearable devices. Furthermore, it should be understood that any of these wearable devices 500A to 500D may include not only a single type of antenna architecture, but may include multiple different types of antenna architectures within the same device. Therefore, Figure 5D The artificial reality glasses 500D may include, for example, both a loop antenna and a dipole antenna, or may include, for example, a monopole antenna, a dipole antenna, and a slot antenna. Many different variations are possible and are contemplated herein.

[0071] In some cases, the wires or traces used to electrically connect the antenna to the corresponding radio device in these various embodiments may be routed differently. FIG. 6A to FIG. 6D As shown, a pair of artificial reality glasses 600A to 600D may include different wire routing embodiments. For example, Fig. 6A An embodiment is shown in which a right wire 601A connecting the right antenna to the radio 603A can run along an interior portion of the artificial reality glasses toward and ultimately over a nose bridge portion of the glasses. A left wire 602A connecting the left antenna to the radio 603A can run along an interior portion of the opposite side of the artificial reality glasses 600A toward the nose bridge but not over the nose bridge. In this way, wires 601A / 602A can be similar in length and, therefore, can provide similar operational capabilities. In some embodiments, one or more radios can be placed in the nose bridge portion of the artificial reality glasses (e.g., as shown in FIG. 1 ). Figure 2D In this case, the lengths of the conductors 601A / 602A may be the same or substantially the same. This may provide greater performance equality between the left and right antennas.

[0072] FIG. 6B to FIG. 6D Other wiring embodiments are shown in FIG. Figure 6B The artificial reality glasses 600B of FIG. 600B may have a left side wire 601B that runs along the inner portion of the artificial reality glasses 600B like wire 601A and may pass over the nose bridge portion of the glasses. However, the right side wire 602B may run from the antenna in the bottom edge portion around the outside of the glasses rim and then along the brow line to the radio device 603B. Figure 6C For the artificial reality glasses 600C, the situation may be the opposite. Figure 6C, the left wire 601C runs along the outer edge and along the brow line of the glasses to the radio device 603C, while the right wire 602C can run along the inner portion of the artificial reality glasses 600C toward the nose bridge and the radio device 603C. Fig.6D In the embodiment, the virtual reality glasses 600D may include a left wire 601D and a right wire 602D, wherein the left wire 601D is wired along the outer edge of the rim of the glasses and along the eyebrow portion to the radio device 603D, and the right wire 602D is wired along the opposite outer edge of the rim of the glasses and along the eyebrow portion to the radio device 603D.

[0073] In some cases, routing the wires along the outer edge of the rim of the glasses can avoid electronic or mechanical components located at the inner edge of the rim of the glasses. In other cases, routing the wires along the inner edge of the rim of the glasses can avoid electronic or mechanical components located at the outer edge or top edge of the rim of the glasses. Therefore, in some cases, it may be more important to avoid routing the wires through one or more components or to avoid specific components (e.g., other antennas) than to have equal length wires between the antenna and the radio device. In this way, the antenna can be intelligently routed (which may be different on each wearable device) to provide the highest level of operating efficiency while avoiding other electronic or mechanical components in the device.

[0074] 7A to 10D Various embodiments are shown in which antennas (e.g., WiFi antennas) can be placed in different portions of the bottom edge portion of the wearable electronic device. As described above, antennas can be placed on both sides of the eye-wearable device to provide separation between the antennas. On a given side of the frame 701A to 701D (e.g., 7A to 10D The antenna can also be placed in different positions within the antenna (shown on the left in FIG). These positions may affect how efficiently the antenna can operate (e.g., send or receive wireless signals). For example, in 7A to 7D , the left antennas 702A to 702D can be centered along the z-axis with respect to the user's face. For example, Figure 4A The left antenna 402A can be positioned on the outer edge of the frame 401A of the virtual reality head mounted device 400A and on the bottom edge portion 407A. 7A to 7D , the left antennas 702A to 702D can be placed between the outer edge of the virtual reality glasses 700A to 700D and the inner edge of the glasses that contacts the cheek of the user (e.g., user 705A to 705D) at a central position along the z-axis. Fig. 7AThe right antenna may be placed in a similar centered position, or may be placed in an outward position near the front face of the artificial reality glasses 700A to 700D. In other cases, the right antenna may be placed in an inward position near the inside of the bottom edge portions 707A to 707D, next to the user's cheek (although still separated from the user's cheek by the overmold and / or molded portion, such as FIG. 3A to FIG. 3D as shown).

[0075] Similarly, if FIG. 8A to FIG. 8D As shown in the embodiment of the embodiment, the left antenna 802A to 802D of the wearable electronic device 800A to 800D can be placed in an inward position of the frame 801A to 801D near the inner side of the bottom edge portion 807A to 807D. In this case, the left antenna 802A to 802D can be placed closer to the face of the user (e.g., user 805A to 805D) to avoid contact with potential other components located in the bottom edge portion 807A to 807D of the wearable electronic device 800A to 800D. In addition, in some cases, the right antenna can be placed in front of the bottom edge portion of the wearable device (e.g., FIG. 4A to FIG. 4D ), and the left antenna can be placed on the back of the bottom edge portion of the wearable device. In this case, the offset of the antenna may be greater and the antenna may experience better isolation. Therefore, FIG. 4A to FIG. 4D , 7A to 7D and FIG. 8A to FIG. 8D As shown, the antenna can be placed at the frontmost position, the middle position, or the rearmost position of the bottom edge portion of the wearable electronic device. In these wearable devices described herein (e.g., Figures 1A to 1J Different antenna placements may be used in each wearable device in 100A to 100J of the present invention. These placements may provide different spherical coverage for each antenna and may provide different levels of efficiency for MIMO and other operations with respect to the second (or third or subsequent) antenna.

[0076] 9A to 10D An embodiment is shown in which the left antenna 902A to 902D or 1002A to 1002D is moved either toward the inner portion of the wearable device or toward the outer edge of the bottom edge portion of the frame (901A to 901D or 1001A to 1001D) of the wearable device 900A and 1000A, respectively. 9A to 9D As can be seen in FIG. 1 , for example, different wearable devices 900A to 900D may place antennas at different locations. 9A to 9D, antennas 902A to 902D can be positioned away from the center of the x-axis and toward the interior portion of the wearable device. The right antenna (not shown) can also be moved in this manner, or can remain in a centered position. Moving both the left and right antennas toward the interior portion of the wearable device can reduce the length of the wires connecting the antennas to one or more radio devices, but may also place the antennas closer together. Therefore, in at least some embodiments, there can be limits on how far the right and left antennas can be moved toward the interior portion of the wearable devices 900A to 900D. In fact, in at least some cases, when the antennas are moved to different positions relative to each other or relative to other antennas, a minimum isolation threshold level for each antenna will be maintained.

[0077] exist FIG. 10A to FIG. 10D , when the wearable glasses are viewed from the front, antennas 1002A to 1002D may be positioned to the right of the center of the x-axis, such as FIG. 10A to FIG. 10D As shown. The left antennas 1002A-1002D can be moved toward the outer portion of the bottom edge of the wearable device 1000A-1000D. This may separate the antennas further on the wearable device, which may result in a higher degree of isolation for each antenna, but such placement may also result in longer wires connecting the antennas 1002A-1002D to the radio device. These longer wires may at least partially reduce the operating efficiency of the antennas, but the increased isolation of each antenna may be sufficient to offset any reduction in antenna efficiency due to longer connecting wires. In some wearable devices, it may not be feasible to route the wires through the middle of the device (e.g., in a virtual reality headset) (e.g., this may block visibility). Therefore, other routing options (e.g., such as FIG. 6A to FIG. 6D shown).

[0078] Fig.11 and Fig.12 A method for manufacturing a wearable electronic device is shown. For example, Fig.11 An exemplary manufacturing method 1100 is provided for manufacturing, assembling, or otherwise producing a wearable electronic device. Fig.11 The steps shown in can be performed by any suitable computer executable code and / or computing system (including the system described herein). In one example, Fig.11 Each of these steps shown in may represent an algorithm whose structure includes and / or is represented by multiple sub-steps, examples of which are provided in more detail below.

[0079] For example, at step 1110, method 1100 may include providing a support structure having a top portion and a first bottom portion. Figure 4AAs shown, the wearable electronic device produced using method 1100 may include a support structure or frame 401A and a top portion 406A and a first bottom portion 407A (e.g., a left bottom portion). Method 1100 may also include: at step 1120, attaching at least one wireless communication device (e.g., Figure 1A The method 1100 may further include assembling at least one antenna 402A on a first bottom portion 407A of the support structure 401A at step 1130. The antenna 402A on the first bottom portion 407A of the support structure 401 may be electrically connected to the wireless communication device 102A positioned on the top portion of the support structure.

[0080] Fig.12 The method 1200 may include manufacturing a wearable electronic device (e.g., Figure 4A 400A). The alternative method may include steps 1210, 1220, and 1230 that are similar or identical to the steps of method 1100, and may include: providing a support structure 401A having a top portion 406A and a first bottom portion 407A (step 1210), assembling at least one wireless communication device 102A on the top portion 406A of the support structure 401A (step 1220), and assembling at least one antenna 402A on the first bottom portion 407A of the support structure 401A (step 1230). The antenna 402A in the first bottom portion 407A of the support structure 401A may be electrically connected to the wireless communication device 102A positioned on the top portion of the support structure. Method 1200 may also include: at step 1240, assembling a second antenna (e.g., 101A) on a vertically offset portion of the frame or support structure 401A (e.g., at a bottom portion opposite a lens of the eyewear device). The method 1200 may also include electrically connecting the second antenna 101A to the wireless communication device 102A at step 1250. Thus, both the antenna 101A and the antennas 402A / 103A may be connected to the radio 102A or multiple radios.

[0081] The antennas (e.g., 101A / 103A) may be placed in the bottom portion of the rim of the eyewear device to avoid interference with other internal components. In addition, the antennas may be vertically offset from each other to provide greater isolation for each antenna. 7A to 10DAs shown, the antennas can be placed at different locations along the bottom portion of the edge. By increasing or decreasing the distance between the antennas, embodiments of the present invention can increase or decrease the amount of isolation provided to each antenna. In addition, moving the antennas toward the front of the wearable device can position the antennas away from the user's head and cheeks, resulting in less and less interference caused by the user's head. This can allow the wearable device to achieve better signal quality at the same amount of power, or it can allow the wearable device to increase the amount of power used by the antenna for transmission or reception. This can be beneficial in remote areas where reception is poor.

[0082] As described above, antenna 101A / 103A can be connected to a corresponding radio device 102A, which can be positioned in the nose bridge portion of the wearable electronic device. Antenna 101A / 103A can be connected to radio device 102A via cables or wires of similar or identical lengths. This can provide greater operating efficiency because each antenna can have similar operating characteristics, including similar impedance levels, similar signal reception levels, etc. In some cases, for example, an electrical connection between the antenna and the radio device can follow the inner contour of the lower right edge of the artificial reality glasses, and a second electrical connection between the second bottom portion and the radio device can follow the inner contour of the lower left edge of the artificial reality glasses (e.g., Fig. 6A ).

[0083] In some cases, the placement of the antenna may vary along the bottom edge of the wearable device (e.g., WiFi, cellular, etc.) based on the antenna type (e.g., WiFi, cellular, etc.) or antenna architecture (e.g., loop, monopole, etc.). 7A to 10D Similarly, the placement of the radios can vary along the top brow portion of the wearable device. In practice, one or more radios can be centered in the top portion of the frame, or can be off-center (e.g., Figure 2A In some cases, multiple different types of radios may be implemented in the top brow portion of the wearable device. These different types of radios may be placed on the brow bar above the user's eyes, inside the bridge of the nose, or on the outer edge of the top portion of the rim.

[0084] In some embodiments, the antennas in the bottom edge portion of the wearable electronic device can be at least partially integrated into a support structure or frame. At least in some cases, the support structure can be made of a conductive metal. Therefore, any one or more of these antennas can be grounded to the support structure. The support structure can support many different electronic components and / or mechanical components. These components can at least partially surround the antennas in the bottom edge portion of the support structure. In some cases, these components can be limited to those components that do not interfere with the operation of the antenna or only slightly affect the function of the antenna. Therefore, during the design and manufacturing process, steps can be taken to ensure that the components around or adjacent to the antenna can be such components: these components will not introduce sensitivity degradation or otherwise adversely affect the operation of the antenna.

[0085] Therefore, systems, manufacturing methods, and devices for improving antenna functionality are provided herein. In practice, the embodiments described herein can provide increased isolation by separating antennas from each other within a wearable device. In addition, sensitivity degradation can be reduced and operating efficiency can be improved by moving one or more antennas to different locations on the bottom edge portion of the wearable device (including on the front of the device), away from the user's head. Furthermore, the antenna can be moved away from other mechanical and electronic components that may interfere with the operating efficiency of the antenna.

[0107] Embodiments of the present disclosure may include various types of artificial reality systems, or be implemented in combination with various types of artificial reality systems. Artificial reality is a form of reality that has been adjusted in some way before being presented to a user, and artificial reality may include, for example, virtual reality, augmented reality, mixed reality (mixed reality or hybrid reality), or some combination and / or derivative thereof. Artificial reality content may include content generated entirely by a computer or computer-generated content combined with collected (e.g., real-world) content. Artificial reality content may include video, audio, tactile feedback, or some combination thereof, any of which may be presented in a single channel or in multiple channels (e.g., stereoscopic video that produces a three-dimensional (3D) 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 artificial reality and / or otherwise used in artificial reality (e.g., performing activities in artificial reality).

[0108] Artificial reality systems can be implemented in a variety of different form factors and configurations. Some artificial reality systems can be designed to work without a near-eye display (NED). Other artificial reality systems can include a NED that also provides visibility to the real world (e.g., Fig.13 ) or an NED that visually immerses a user in an artificial reality (e.g., Fig.14 1400 in the virtual reality system 1400). Although some artificial reality devices may be stand-alone systems, other artificial reality devices may communicate and / or coordinate with external devices to provide an artificial reality experience to a user. Examples of such external devices include handheld controllers, mobile devices, desktop computers, devices worn by a user, devices worn by one or more other users, and / or any other suitable external system.

[0109] Go to Fig.13 , the augmented reality system 1300 may include an eyewear device 1302 having a frame 1310 configured to hold a left display device 1315(A) and a right display device 1315(B) in front of the user's eyes. Display devices 1315(A) and 1315(B) may function together or independently to present an image or a series of images to the user. Although the augmented reality system 1300 includes two displays, embodiments of the present disclosure may be implemented in an augmented reality system having a single NED or more than two NEDs.

[0110] In some embodiments, the augmented reality system 1300 may include one or more sensors, such as sensor 1340. Sensor 1340 may generate measurement signals in response to the movement of the augmented reality system 1300 and may be located on substantially any portion of the frame 1310. Sensor 1340 may represent one or more of a variety of different sensing mechanisms, such as a position sensor, an inertial measurement unit (IMU), a depth camera assembly, a structured light emitter and / or detector, or any combination thereof. In some embodiments, the augmented reality system 1300 may or may not include sensor 1340, or may include more than one sensor. In embodiments where sensor 1340 includes an IMU, the IMU may generate calibration data based on the measurement signals from sensor 1340. Examples of sensor 1340 may include, but are not limited to, accelerometers, gyroscopes, magnetometers, other suitable types of sensors that detect movement, sensors for error correction of an IMU, or some combination thereof.

[0111] In some examples, the augmented reality system 1300 may also include a microphone array having a plurality of acoustic transducers 1320(A) to 1320(J) (collectively referred to as acoustic transducers 1320). Acoustic transducers 1320 may represent transducers that detect changes in air pressure caused by sound waves. Each acoustic transducer 1320 may be configured to detect sound and convert the detected sound into an electronic format (e.g., an analog format or a digital format). Fig.13 The microphone array in can include, for example, ten acoustic transducers: 1320(A) and 1320(B), which can be designed to be placed in the corresponding ears of the user; acoustic transducers 1320(C), 1320(D), 1320(E), 1320(F), 1320(G) and 1320(H), which can be located at various positions on the frame 1310; and / or acoustic transducers 1320(I) and 1320(J), which can be located on the corresponding neckband 1305.

[0112] In some embodiments, one or more of acoustic transducers 1320(A) to 1320(J) may be used as an output transducer (e.g., a speaker). For example, acoustic transducers 1320(A) and / or 1320(B) may be earbuds, or any other suitable type of earphone or speaker.

[0113] The configuration of the acoustic transducer 1320 of the microphone array may vary. Fig.13 1310, but the number of acoustic transducers 1320 may be more or less than ten. In some embodiments, using a greater number of acoustic transducers 1320 may increase the amount of audio information collected and / or the sensitivity and accuracy of the audio information. In contrast, using a smaller number of acoustic transducers 1320 may reduce the computing power required for the associated controller 1350 to process the collected audio information. In addition, the position of each acoustic transducer 1320 of the microphone array may vary. For example, the position of the acoustic transducer 1320 may include a defined position on the user, a defined coordinate on the frame 1310, an orientation associated with each acoustic transducer 1320, or some combination thereof.

[0114] The acoustic transducers 1320(A) and 1320(B) can be located on different parts of the user's ear, such as behind the pinna, behind the tragus, and / or in the auricle or ear cavity. Alternatively, in addition to the acoustic transducer 1320 in the ear canal, additional acoustic transducers 1320 can be present on or around the ear. Having an acoustic transducer 1320 located near the user's ear canal can enable the microphone array to collect information about how sound reaches the ear canal. By positioning at least two acoustic transducers 1320 on both sides of the user's head (e.g., as binaural microphones), the augmented reality system 1300 can simulate binaural hearing and capture a 3D stereo field around the user's head. In some embodiments, acoustic transducers 1320(A) and 1320(B) may be connected to augmented reality system 1300 via wired connection 1330, while in other embodiments, acoustic transducers 1320(A) and 1320(B) may be connected to augmented reality system 1300 via a wireless connection (e.g., a Bluetooth connection). In other embodiments, acoustic transducers 1320(A) and 1320(B) may not be used in conjunction with augmented reality system 1300 at all.

[0115] The acoustic transducers 1320 on the frame 1310 can be positioned in a variety of different ways, including along the length of the temples, across the bridge, above or below the display devices 1315(A) and 1315(B), or some combination thereof. The acoustic transducers 1320 can also be oriented so that the microphone array can detect sounds from a wide range of directions around the user wearing the augmented reality system 1300. In some embodiments, an optimization process can be performed during the manufacture of the augmented reality system 1300 to determine the relative positioning of each acoustic transducer 1320 in the microphone array.

[0116] In some examples, the augmented reality system 1300 may include or may be connected to an external device (e.g., a paired device), such as a neckband 1305. The neckband 1305 generally represents any type or form of paired device. Therefore, the discussion below on the neckband 1305 may also be applied to various other paired devices, such as charging boxes, smart watches, smart phones, wristbands, other wearable devices, handheld controllers, tablet computers, laptop computers, other external computing devices, etc.

[0117] As shown, the neckband 1305 can be coupled to the eye-wear device 1302 via one or more connectors. These connectors can be wired or wireless and can include electronic components and / or non-electronic components (e.g., structural components). In some cases, the eye-wear device 1302 and the neckband 1305 can operate independently without any wired or wireless connection between them. Although Fig.13 Components of the eyewear device 1302 and components of the neckband 1305 are shown located in example locations on the eyewear device 1302 and the neckband 1305, but these components can be located in other locations on the eyewear device 1302 and / or the neckband 1305 and / or distributed differently on the eyewear device 1302 and / or the neckband 1305. In some embodiments, components of the eyewear device 1302 and components of the neckband 1305 can be located on one or more additional peripheral devices that are paired with the eyewear device 1302, the neckband 1305, or some combination thereof.

[0118] Pairing an external device, such as a neckband 1305, with an augmented reality eyewear device can enable the eyewear device to achieve the form factor of a pair of glasses and still provide sufficient battery power and computing power for the expanded capabilities. Some or all of the battery power, computing resources, and / or additional features of the augmented reality system 1300 can be provided by a paired device, or shared between a paired device and the eyewear device, thereby reducing the weight, thermal distribution, and form factor of the eyewear device as a whole while still retaining the desired functionality. For example, the neckband 1305 can allow components that would otherwise be included on the eyewear device to be included in the neckband 1305 because the user can bear a heavier weight load on their shoulders than the user bears on their head. The neckband 1305 can also have a larger surface area to diffuse and disperse heat to the surrounding environment over the larger surface area. Thus, the neckband 1305 can allow for greater battery power and computing power than would otherwise be possible on a standalone eyewear device. Because the weight carried in the neckband 1305 can be less invasive to the user than the weight carried in the eye-wearing device 1302, the user can tolerate wearing a lighter eye-wearing device and carrying or wearing a paired device for a longer period of time than the user can tolerate wearing a heavy stand-alone eye-wearing device, thereby enabling the user to more fully integrate the artificial reality environment into their daily activities.

[0119] The neck strap 1305 can be communicatively coupled to the eyewear device 1302 and / or other devices. These other devices can provide certain functions (e.g., tracking, positioning, depth map construction, processing, storage, etc.) for the augmented reality system 1300. Fig.13 In an embodiment of the present invention, the neckband 1305 may include two acoustic transducers (e.g., 1320 (I) and 1320 (J)), which are part of the microphone array (or potentially form their own microphone sub-array). The neckband 1305 may also include a controller 1325 and a power supply 1335.

[0120] The acoustic transducers 1320(I) and 1320(J) of the neckband 1305 may be configured to detect sound and convert the detected sound into an electronic format (analog or digital). Fig.13In an embodiment of the present invention, the acoustic transducers 1320(I) and 1320(J) can be positioned on the neckband 1305, thereby increasing the distance between the acoustic transducers 1320(I) and 1320(J) of the neckband and other acoustic transducers 1320 positioned on the eye-wear device 1302. In some cases, increasing the distance between the acoustic transducers 1320 of the microphone array can improve the accuracy of beamforming performed via the microphone array. For example, if the acoustic transducers 1320(C) and 1320(D) detect a sound, and the distance between the acoustic transducers 1320(C) and 1320(D) is greater than, for example, the distance between the acoustic transducers 1320(D) and 1320(E), the source location of the detected sound can be determined to be more accurate than the source location of the sound determined when the sound is detected by the acoustic transducers 1320(D) and 1320(E).

[0121] The controller 1325 of the neckband 1305 can process information generated by sensors on the neckband 1305 and / or on the augmented reality system 1300. For example, the controller 1325 can process information from the microphone array that describes the sound detected by the microphone array. For each detected sound, the controller 1325 can perform a Direction-Of-Arrival (DOA) estimate to estimate the direction from which the detected sound arrives at the microphone array. When the microphone array detects a sound, the controller 1325 can fill the audio data set with this information. In an embodiment where the augmented reality system 1300 includes an inertial measurement unit, the controller 1325 can calculate all inertial and spatial operations based on the IMU located on the eye-wearing device 1302. The connector can transmit information between the augmented reality system 1300 and the neckband 1305 and between the augmented reality system 1300 and the controller 1325. The information can be in the form of optical data, electronic data, wireless data, or any other transmittable data form. Moving the processing of information generated by the augmented reality system 1300 to the neck strap 1305 can reduce the weight and heat of the eye-wearing device 1302, making the eye-wearing device more comfortable for the user.

[0122] The power supply 1335 in the neckband 1305 can provide power to the eye-wearing device 1302 and / or the neckband 1305. The power supply 1335 can include, but is not limited to, lithium-ion batteries, lithium polymer batteries, disposable lithium batteries, alkaline batteries, or any other form of power storage device. In some cases, the power supply 1335 can be a wired power supply. Including the power supply 1335 on the neckband 1305 instead of on the eye-wearing device 1302 can help better distribute the weight and heat generated by the power supply 1335.

[0123] As mentioned, some artificial reality systems can substantially replace one or more of a user's sensory perceptions of the real world with a virtual experience, rather than mixing the artificial reality with actual reality. An example of this type of system is a head-mounted display system that largely or completely covers the user's field of view, such as Fig.14 1400. Virtual reality system 1400 may include a front rigid body 1402 and a strap 1404 shaped to fit around a user's head. Virtual reality system 1400 may also include output audio transducers 1406 (A) and 1406 (B). Fig.14 Not shown, but the front rigid body 1402 may include one or more electronic components, including one or more electronic displays, one or more inertial measurement units (IMUs), one or more tracking transmitters or detectors, and / or any other suitable device or system for creating an artificial reality experience.

[0124] Artificial reality systems may include various types of visual feedback mechanisms. For example, the display device in the augmented reality system 1300 and / or the display device in the virtual reality system 1400 may include one or more liquid crystal displays (LCD), light emitting diodes (LED) displays, micro LED displays, organic LED (OLED) displays, digital light projection (DLP) micro displays, liquid crystal on silicon (LCoS) micro displays, and / or any other suitable type of display screen. These artificial reality systems 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 the user's refractive error. Some of these artificial reality systems may also include an optical subsystem having one or more lenses (e.g., concave or convex lenses, Fresnel lenses, adjustable liquid lenses, etc.), through which the user may view the display screen. These optical subsystems can be used for a variety of purposes, including collimating light (e.g., making an object appear to be at a greater distance than it is physically at), amplifying light (e.g., making an object appear larger than its actual size), and / or relaying light (e.g., relaying light to a viewer's eye). These optical subsystems can be used in a direct-view architecture (e.g., a single lens configuration that directly collimates light but causes so-called pincushion distortion) and / or a non-direct-view architecture (e.g., a multi-lens configuration that produces so-called barrel distortion to eliminate pincushion distortion).

[0125] In addition to or in lieu of using a display screen, some of the artificial reality systems described herein may include one or more projection systems. For example, a display device in the augmented reality system 1300 and / or a display device in the virtual reality system 1400 may include a micro-LED projector that projects light into the display device (using, for example, a waveguide), 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 artificial reality content and the real world simultaneously. The display device may achieve this using any of a variety of different optical components, including waveguide components (e.g., holographic waveguide elements, planar waveguide elements, diffractive waveguide elements, polarizing waveguide elements, and / or reflective waveguide elements), light manipulation surfaces and elements (such as diffractive elements and gratings, reflective elements and gratings, and refractive elements and gratings), coupling elements, and the like. The artificial reality system may also be configured with any other suitable type or form of image projection system, such as a retinal projector used in a virtual retinal display.

[0126] The artificial reality systems described herein may also include various types of computer vision components and subsystems. For example, the augmented reality system 1300 and / or the virtual reality system 1400 may include one or more optical sensors, such as a two-dimensional (2D) camera or a 3D camera, a structured light emitter and detector, a time-of-flight depth sensor, a single beam rangefinder or a scanning laser rangefinder, a 3D laser radar (LiDAR) sensor, and / or any other suitable type or form of optical sensor. The artificial reality system may process data from one or more of these sensors to identify the user's location, map the real world, provide the user with content about the real-world surroundings, and / or perform various other functions.

[0127] The artificial reality system described herein may also include one or more input audio converters and / or output audio converters. The output audio converter may include a voice coil speaker, a ribbon speaker, an electrostatic speaker, a piezoelectric speaker, a bone conduction converter, a cartilage conduction converter, an ear tragus vibration converter, and / or any other suitable type or form of audio converter. Similarly, the input audio converter may include a condenser microphone, a dynamic microphone, a ribbon microphone, and / or any other type or form of input converter. In some embodiments, a single converter may be used for both audio input and audio output.

[0128] In some embodiments, the artificial reality systems described herein may also include tactile (i.e., haptic) feedback systems that may be incorporated into headwear, gloves, clothing, handheld controllers, environmental devices (e.g., chairs, floor mats, etc.), and / or any other type of device or system. The tactile feedback system may provide various types of skin feedback including vibration, force, traction, texture, and / or temperature. The tactile feedback system may also provide various types of kinesthetic feedback, such as motion and compliance. Tactile feedback may be implemented using motors, piezoelectric actuators, fluid systems, and / or various other types of feedback mechanisms. The tactile feedback system may be implemented independently of other artificial reality devices, within other artificial reality devices, and / or in combination with other artificial reality devices.

[0129] By providing tactile perception, auditory content, and / or visual content, artificial reality systems can create a complete virtual experience or enhance the user's real-world experience in various situations and environments. For example, an artificial reality system can assist or expand a user's perception, memory, or cognition in a specific environment. Some systems can enhance the user's interaction with other people in the real world, or can achieve a more immersive interaction with other people in the virtual world. Artificial reality systems can also be used for educational purposes (e.g., for teaching or training in schools, hospitals, government organizations, military organizations, commercial enterprises, etc.), entertainment purposes (e.g., for playing video games, listening to music, watching video content, etc.), and / or for access purposes (e.g., as hearing aids, visual aids, etc.). The embodiments disclosed herein can implement or enhance the user's artificial reality experience in one or more of these situations and environments and / or in other situations and environments.

[0130] As noted, artificial reality systems 1300 and 1400 can be used with various other types of devices to provide a more engaging artificial reality experience. These devices can be tactile interfaces with transducers that provide tactile feedback and / or collect tactile information about the user's interaction with the environment. The artificial reality systems disclosed herein can include various types of tactile interfaces that detect or transmit various types of tactile information, including tactile feedback (e.g., feedback detected by the user via nerves in the skin, which feedback may also be referred to as skin feedback) and / or kinesthetic feedback (e.g., feedback detected by the user via receptors located in muscles, joints, and / or tendons).

[0131] Haptic feedback may be provided by an interface positioned within the user's environment (e.g., a chair, table, floor, etc.) and / or by an interface on an item that may be worn or carried by the user (e.g., a glove, wristband, etc.). As an example, Fig.15A vibrotactile system 1500 in the form of a wearable glove (haptic device 1510) and a wristband (haptic device 1520) is shown. The haptic device 1510 and the haptic device 1520 are shown as examples of wearable devices and include a flexible wearable textile material 1530 that is shaped and configured to be positioned against a user's hand and wrist, respectively. The present disclosure also includes a vibrotactile system that can be shaped and configured to be positioned against other human body parts (e.g., fingers, arms, heads, torsos, feet, or legs). As an example and not limitation, the vibrotactile system according to various embodiments of the present disclosure may also be in the form of a glove, a headband, an armband, a sleeve, a headgear, a sock, a shirt, or pants, as well as other possible forms. In some examples, the term "textile" may include any flexible wearable material, including woven fabrics, non-woven fabrics, leather, cloth, flexible polymer materials, composite materials, and the like.

[0132] One or more vibrotactile devices 1540 may be at least partially positioned within one or more corresponding pockets formed in textile material 1530 of vibrotactile system 1500. Vibrotactile devices 1540 may be positioned in appropriate locations to provide a vibrotactile sensation (e.g., tactile feedback) to a user of vibrotactile system 1500. For example, Fig.15 As shown, the vibrotactile device 1540 can be positioned against the user's thumb, one or more other fingers, or wrist. In some examples, the vibrotactile device 1540 can be flexible enough to conform to or bend with one or more corresponding body parts of the user.

[0133] A power source 1550 (e.g., a battery) for applying voltage to the vibrotactile device 1540 to activate it can be electrically coupled to the vibrotactile device 1540, for example, via conductive wiring 1552. In some examples, each of these vibrotactile devices 1540 can be independently electrically coupled to the power source 1550 for individual activation. In some embodiments, the processor 1560 can be operatively coupled to the power source 1550 and configured (e.g., programmed) to control the activation of the vibrotactile device 1540.

[0134] The vibrotactile system 1500 can be implemented in various ways. In some examples, the vibrotactile system 1500 can be an independent system with integrated subsystems and components for operating independently of other devices and systems. As another example, the vibrotactile system 1500 can be configured to interact with another device or system 1570. For example, in some examples, the vibrotactile system 1500 can include a communication interface 1580 for receiving signals from another device or system 1570 and / or sending signals to another device or system 1570. Another device or system 1570 can be a mobile device, a game console, an artificial reality (e.g., virtual reality, augmented reality, mixed reality) device, a personal computer, a tablet computer, a network device (e.g., a modem, a router, etc.), a handheld controller, etc. The communication interface 1580 can enable communication between the vibrotactile system 1500 and another device or system 1570 via a wireless (e.g., Wi-Fi, Bluetooth (BLUETOOTH), cellular, radio, etc.) link or a wired link. If present, communication interface 1580 may communicate with processor 1560 , such as providing signals to processor 1560 to activate or deactivate one or more of vibrotactile devices 1540 .

[0135] The vibrotactile system 1500 may optionally include other subsystems and components, such as a touch-sensitive pad 1590, a pressure sensor, a motion sensor, a position sensor, an illumination element, and / or a user interface element (e.g., an on / off button, a vibration control element, etc.). During use, the vibrotactile device 1540 may be configured to be activated for a variety of different reasons, such as in response to user interaction with a user interface element, a signal from a motion or position sensor, a signal from the touch-sensitive pad 1590, a signal from a pressure sensor, a signal from another device or system 1570, etc.

[0136] Although the power supply 1550, the processor 1560 and the communication interface 1580 are Fig.15 1520, but the present disclosure is not limited thereto. For example, one or more of the power supply 1550, the processor 1560, or the communication interface 1580 may be positioned within the haptic device 1510 or within another wearable textile.

[0137] Haptic wearables (e.g., combined with Fig.15 The haptic wearable shown and described may be implemented in various types of artificial reality systems and environments. Fig.16An exemplary artificial reality environment 1600 including a head-mounted virtual reality display and two haptic devices (i.e., gloves) is shown, and in other embodiments, any number of these components and other components, and / or combinations of these components and other components may be included in the artificial reality system. For example, in some embodiments, there may be multiple head-mounted displays, each head-mounted display having an associated haptic device, wherein each head-mounted display and each haptic device communicate with the same console, portable computing device, or other computing system.

[0138] Head mounted display 1602 generally represents any type or form of virtual reality system, such as Fig.14 1400 in the virtual reality system 1400. The haptic device 1604 generally represents any type or form of wearable device worn by a user of the artificial reality system that provides tactile feedback to the user to give the user a sense of physical engagement with a virtual object. In some examples, the haptic device 1604 can provide tactile feedback by applying vibration, motion, and / or force to the user. For example, the haptic device 1604 can limit or enhance the movement of the user. To give a specific example, the haptic device 1604 can limit the forward movement of the user's hand so that the user feels that his or her hand has physically contacted the virtual wall. In this specific example, one or more actuators within the haptic device can achieve physical movement restriction by pumping fluid into an inflatable bladder of the haptic device. In some examples, the user can also use the haptic device 1604 to send an action request to the console. Examples of action requests include, but are not limited to, requests to start an application and / or terminate an application and / or requests to perform a specific action within an application.

[0139] Although tactile interfaces can be used with virtual reality systems (such as Fig.16 ), but tactile interfaces can also be used with augmented reality systems (such as Fig.17 shown). Fig.17 17 is a stereoscopic diagram of a user 1710 interacting with an augmented reality system 1700. In this example, the user 1710 may wear a pair of augmented reality glasses 1720, which may have one or more displays 1722 and be paired with a haptic device 1730. In this example, the haptic device 1730 may be a wristband including a plurality of strap elements 1732 and a tensioning mechanism 1734 connecting the plurality of strap elements 1732 to each other.

[0140] One or more of the plurality of band elements 1732 may include any type or form of actuator suitable for providing tactile feedback. For example, one or more of the plurality of band elements 1732 may be configured to provide one or more of various types of skin feedback, including vibration, force, traction, texture, and / or temperature. In order to provide such feedback, the plurality of band elements 1732 may include one or more of various types of actuators. In one example, each of the band elements 1732 may include a vibrotactile (e.g., a vibrotactile actuator) configured to vibrate in unison or independently to provide one or more of various types of tactile sensations to the user. Alternatively, only a single band element or a subset of the plurality of band elements may include a vibrotactile.

[0141] The haptic devices 1510, 1520, 1604, and 1730 may include any suitable number and / or type of tactile transducers, sensors, and / or feedback mechanisms. For example, the haptic devices 1510, 1520, 1604, and 1730 may include one or more mechanical transducers, one or more piezoelectric transducers, and / or one or more fluid transducers. The haptic devices 1510, 1520, 1604, and 1730 may also include various combinations of transducers of different types and forms that work together or independently to enhance the user's artificial reality experience. In one example, each of the plurality of band elements 1732 of the haptic device 1730 may include a vibrating tactile (e.g., a vibrating tactile actuator) that is configured to vibrate in unison or independently to provide one or more of various types of tactile sensations to the user.

[0142] Fig.18A An exemplary human-machine interface (also referred to herein as an EMG control interface) configured to be worn around the forearm or wrist of a user as a wearable system 1800 is shown. In this example, the wearable system 1800 may include sixteen neuromuscular sensors 1810 (e.g., EMG sensors) arranged circumferentially around an elastic band 1820, the inner surfaces of which are configured to contact the user's skin. However, any appropriate number of neuromuscular sensors may be used. The number and arrangement of neuromuscular sensors may depend on the specific application in which the wearable device is used. For example, a wearable armband or wristband may be used to generate control information for controlling an augmented reality system, a robot, controlling a vehicle, scrolling through text, controlling a virtual avatar, or any other suitable control task. As shown, the sensors may be coupled together using flexible electronics incorporated into a wireless device. Fig.18B Shown through Fig.18A. In some embodiments, the output of one or more of the plurality of sensing components may optionally be processed using hardware signal processing circuitry (e.g., for performing amplification, filtering, and / or rectification). In other embodiments, at least some of the signal processing on the output of the sensing component may be performed in software. Thus, signal processing on the signal sampled by the sensor may be performed by hardware, software, or by any suitable combination of hardware and software, as aspects of the technology described herein are not limited in this respect. Reference is made below to Fig.19A and Fig.19B A non-limiting example of a signal processing chain for processing recorded data from sensor 1810 is discussed in more detail.

[0143] Fig.19A and Fig.19B An exemplary schematic diagram of the internal components of a wearable system with an EMG sensor is shown. As shown, the wearable system may include a wearable portion 1910 ( Fig.19A ) and a dongle portion 1920 (which communicates with the wearable portion 1910 (eg, via Bluetooth or another suitable wireless communication technology) Fig.19B ).like Fig.19A As shown, the wearable portion 1910 may include a skin contact electrode 1911, and an example of the skin contact electrode 1911 is combined with Fig.18A and Fig.18B The output of skin contact electrode 1911 may be provided to analog front end 1930, which may be configured to perform analog processing (e.g., amplification, noise reduction, filtering, etc.) on the recorded signal. The processed analog signal may then be provided to analog-to-digital converter (ADC) 1932, which may convert the analog signal into a digital signal that may be processed by one or more computer processors. Examples of computer processors that may be used according to some embodiments are Fig.19A 1934. As shown, the MCU 1934 may also include inputs from other sensors (e.g., IMU sensor 1940) and power and battery module 1942. The output of the processing performed by the MCU 1934 may be provided to an antenna 1950 for transmission to Fig.19B The dongle portion 1920 is shown in FIG.

[0144] The dongle portion 1920 may include an antenna 1952 that may be configured to communicate with an antenna 1950 included as part of the wearable portion 1910. Communication between the antenna 1950 and the antenna 1952 may be performed using any suitable wireless technology and protocol, non-limiting examples of which include radio frequency signaling and Bluetooth. As shown, the signal received by the antenna 1952 of the dongle portion 1920 may be provided to a host computer for further processing, display, and / or enabling control of a particular physical object or one or more virtual objects.

[0145] Although reference FIG. 18A to FIG. 18B and FIG. 19A to FIG. 19B The examples provided are discussed in the context of interfaces with EMG sensors, but the techniques described herein for reducing electromagnetic interference may also be implemented in wearable interfaces with other types of sensors, including but not limited to mechanomyography (MMG) sensors, sonomyography (SMG) sensors, and electrical impedance tomography (EIT) sensors. The techniques described herein for reducing electromagnetic interference may also be implemented in wearable interfaces that communicate with a computer host via wires and cables (e.g., Universal Serial Bus (USB) cables, fiber optic cables, etc.).
