[0033] Numerous details are described herein to provide a thorough understanding of the example embodiments illustrated in the accompanying drawings. However, some embodiments may be practiced without many of the specific details, and the scope of the claims is only limited by those features and aspects specifically recited in the claims. Furthermore, well-known processes, components, and materials have not necessarily been described in exhaustive detail so as to avoid obscuring pertinent aspects of the embodiments described herein.Overview

[0034] Embodiments of this disclosure can include or be implemented in conjunction with various t pes of extended-realities (XRs) such as mixed-reality (MR) and augmented-reality (AR) systems. MRs and ARs, as described herein, are any superimposed functionality and / or sensory-detectable presentation provided by MR and AR systems within a user’s physical surroundings. Such MRs can include and / or represent virtual realities (VRs) and VRs in which at least some aspects of the surrounding environment are reconstructed within the virtual environment (e.g., displaying virtual reconstructions of physical objects in a physical environment to avoid the user colliding with the physical objects in a surrounding physical environment). In the case of MRs, the surrounding environment that is presented through a display is captured via one or more sensors configured to capture the surrounding environment (e.g., a camera sensor and / or a time-of-flight (ToF) sensor). While a wearer of an MR headsetcan see the surrounding environment in full detail, they are seeing a reconstruction of the environment reproduced using data from the one or more sensors (i.e., the physical objects are not directly viewed by the user). An MR headset can also forgo displaying reconstructions of objects in the physical environment, thereby providing a user with an entirely VR experience. An AR system, on the other hand, provides an experience in which information is provided, e.g., through the use of a waveguide, in conjunction with the direct viewing of at least some of the surrounding environment through a transparent or semi-transparent waveguide(s) and / or lens(es) of the AR glasses. Throughout this application, the term “extended reality (XR)” is used as a catchall term to cover both ARs and MRs. In addition, this application also uses, at times, a head-wearable device or headset device as a catchall term that covers XR headsets such as AR glasses and MR headsets.

[0035] As alluded to above, an MR environment, as described herein, can include, but is not limited to, non-immersive, semi-immersive, and fully immersive VR environments. As also alluded to above, AR environments can include marker-based AR environments, markerless AR environments, location-based AR environments, and projection-based AR environments. The above descriptions are not exhaustive, and any other environment that allows for intentional environmental lighting to pass through to the user would fall within the scope of an AR, and any other environment that does not allow' for intentional environmental lighting to pass through to the user would fall within the scope of an MR.

[0036] The AR and MR content can include video, audio, haptic events, sensory events, or some combination thereof, any of which can be presented in a single channel or in multiple channels (such as stereo video that produces a three-dimensional effect to a viewer). Additionally, AR and MR can also be associated with applications, products, accessories, or services, or some combination thereof, that are used, for example, to create content in an AR or MR environment and / or are otherwise used in (e.g., to perform activities in) AR and MR environments.

[0037] Interacting with these AR and MR environments described herein can occur using multiple different modalities and the resulting outputs can also occur across multiple different modalities. In one example AR or MR system, a user can perform a swiping in-air hand gesture to cause a song to be skipped by a song-providing application programming interface (API) providing playback at, for example, a home speaker.

[0038] A hand gesture, as described herein, can include an in-air gesture, a surfacecontact gesture, and / or other gestures that can be detected and determined based on movements of a single hand (e.g., a one-handed gesture performed with a user’s hand that is detected byone or more sensors of a wearable device (e.g., electromyography (EMG) and / or inertial measurement units (IMUs) of a wrist-wearable device, and / or one or more sensors included in a smart textile wearable device) and / or detected via image data captured by an imaging device of a wearable device (e.g., a camera of a head-wearable device or an external tracking camera that is set up in the surrounding environment)). “In-aif ’ generally includes gestures in which the user's hand does not contact a surface, object, or portion of an electronic device (e.g., a head-wearable device or other communicatively coupled device, such as the wrist-wearable device); in other words, the gesture is performed in open air in 3D space and without contacting a surface, an object, or an electronic device. Surface-contact gestures (contacts at a surface, object, body part of the user, or electronic device) more generally are also contemplated in which a contact (or an intention to contact) is detected at a surface (e.g., a single- or doublefinger tap on a table, on a user’s hand or another finger, on the user’s leg, a couch, and / or a steering wheel). The different hand 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, ToF sensors, sensors of an IMU, capacitive sensors, and / or strain sensors) detected by a wearable device worn by the user and / or other electronic devices in the user’s possession (e.g., smartphones, laptops, imaging devices, intermediary' devices, and / or other devices described herein).

[0039] The input modalities as alluded to above can be varied and are dependent on a user’s experience. For example, in an interaction in which a wrist- wearable device is used, a user can provide inputs using in-air or surface-contact gestures that are detected using neuromuscular signal sensors of the wrist-wearable device. In the event that a wrist-wearable device is not used, alternative and entirely interchangeable input modalities can be used instead, such as camera(s) located on the headset / glasses or elsewhere to detect in-air or surface-contact gestures or inputs at an intermediary processing device (e.g., through physical input components (e.g., buttons and trackpads)). These different input modalities can be interchanged based on desired user experiences, portability, and / or a feature set of the product (e.g., a low-cost product may not include hand-tracking cameras).

[0040] While the inputs are varied, the resulting outputs stemming from the inputs are also varied. For example, an in-air gesture input detected by a camera of a head-wearable device can cause an output to occur at a head-wearable device or control another electronic device different from the head-wearable device. In another example, an input detected using data from a neuromuscular signal sensor can also cause an output to occur at a head-wearabledevice or control another electronic device different from the head-wearable device. While only a couple examples are described above, one skilled in the art would understand that different input modalities are interchangeable along with different output modalities in response to the inputs.

[0041] Specific operations described above may occur as a result of specific hardware. The devices described are not limiting, and features on these devices can be removed or additional features can be added to these devices. The different devices can include one or more analogous hardware components. For brevity, analogous devices and components are described herein.

[0052] Figures 1A-1B illustrate examples of a display assembly mounted to a lens frame of a first type (e.g., front lens frame 102 and rear lens frame 104) and a lens frame of a second type (e.g., front lens frame 103 and rear lens frame 105), respectively, for augmented-reality glasses 100, in accordance with some embodiments. As shown in Figure 1A, the augmented-reality glasses 100 include a front lens frame 102 that is configured to couple to arear lens frame 104, and in Figure IB, the augmented-reality glasses 100 include a front lens frame 103 (distinct from front lens frame 102) that is configured to couple to a rear lens frame 105 (distinct from rear lens frame 104). The augmented-reality glasses 100 further include a display assembly 108 that is configured to couple to the front lens frame 102 and the rear lens frame 104.

[0053] As show n in Figure 1A, in an exploded view, the display assembly 108 includes a display projector assembly 106 and a lens stack (which is described in more detail with respect to Figure 3).

[0054] In some embodiments, the display assembly 108 is modular, thereby allowing the display assembly to be coupled to vary ing lens frames. In addition to being modular to fit in different frames, the display assembly 108 is also configured to be fully assembled separately from the rest of the augmented-reality glasses 100. Since the display assembly 108 is assembled separately, the display assembly 108 can be tested and / or validated without testing and / or validation of the entire augmented-reality glasses. Furthermore, such testing and / or validation can occur earlier in the manufacturing process.

[0055] As shown in Figure 1A, the fully assembled display assembly 108 is then mounted to the front lens frame 102 and the rear lens frame 104. The display projector assembly 106 includes a first connector 112 and a second connector 114. The first connector 112 and the second connector 114 are configured to couple to other components of the augmented-reality glasses 100. For example, the first connector 112 and / or the second connector 114 are configured to enable power and data transfer between the display projector assembly 106 and other components of the augmented-reality glasses.

[0056] In some embodiments, the augmented-reality glasses 100 include a disparity sensor assembly 110. The disparity’ sensor assembly 110 is configured to couple to the modular display assembly 108 and / or another modular display assembly. The disparity sensor assembly 110 may also be configured to couple to the front lens frame 102 and / or the rear lens frame 104. In some embodiments, the disparity sensor assembly 110 is also modular, and its functionality can also be checked prior to final assembly of the augmented-reality’ glasses 100.

[0057] In some embodiments, the display proj ector assembly 106 is coupled to the front lens frame 102 and / or the rear lens frame 104 such that heat is transferred from the display projector assembly 106 to other parts of the augmented-reality’ glasses 100 (e.g., to the frame, arms, or other portions of the glasses that can act as a heat sink). The display projector assembly 106 can be coupled to the front lens frame 102 and / or the rear lens frame 104 via a thermally conductive material (e.g., a thermally conductive pad and / or paste).

[0058] As shown in Figure IB, in an exploded view, the fully assembled display assembly 108 that can be mounted in the front lens frame 102 and the rear lens frame 104 (as shown in Figure 1A) can also be mounted into the front lens frame 103 and the rear lens frame 105. Stated differently, display assembly 108 and corresponding lens frame(s) are configured such that the display assembly 108 can be mounted to the lens frame(s) having different geometries, shapes, and / or dimensions.

[0059] Figure 2 illustrates an example of locating features for alignment of the display assembly and lens frames of the augmented-reality glasses, in accordance with some embodiments. The locating features described herein are universal across different (e.g., different shapes and sizes) augmented-reality glasses, thereby allowing the same modular display assembly to be assembled in the same manner across the different devices. As shown in Figure 2, the front lens frame 102 includes a temple-locating feature 202 and a nasal-locating feature 210. Additionally, the display assembly 108 includes a temple-locating feature 204 and a nasal-locating feature 212. Further, the rear lens frame 104 includes a temple-locating feature 206 and a nasal-locating feature 214. The locating features are configured to couple together such that the front lens frame 102, the display assembly 108. and the rear lens frame 104 are aligned. In one example, the locating features of the front lens frame 102 is a socket (e.g., a hole) and the locating feature of the rear lens frame 104 is a pin (e.g., a dowel), and the socket is configured to couple to the pin such that the front lens frame 102 and the rear lens frame 104 are in the correct relative location to each other. In this example, the locating features of the display assembly 108 is a notch or hole through which the pin of the rear lens frame 104 is inserted through. When the display assembly 108 is positioned between the front lens frame 102 and the rear lens frame 104. the display assembly is held in alignment with the front and rear lens frames by the pin.

[0060] In another example, the locating features of the front lens frame 102, the rear lens frame 104, and the display assembly 108 can be through holes and / or threaded to accept fasteners (e.g., a screw, a bolt, and / or other types of fasteners). For example, the templelocating feature 202 and the nasal-locating feature 210 of the front lens frame 102, and the temple-locating feature 204 and the nasal-locating feature 212 of the display assembly 108, are through holes. Additionally, the temple-locating feature 206 and the nasal-locating feature 214 of the rear lens frame 104 are threaded (e.g., a threaded insert). In this example, a first fastener is inserted along path 208 such that it interfaces with the temple-locating features of the front lens frame 102 and the display assembly 108, and is secured to the temple-locating feature 206 of the rear lens frame 104. Additionally, a second fastener is inserted along path 208 such thatit interfaces with the nasal-locating features of the front lens frame 102 and the display assembly 108, and is secured to the nasal-locating feature 206 of the rear lens frame 104. When assembled, the combination of the locating features and the fastener align the respective components.

[0061] In some embodiments, the temple-locating features 202, 204, and 206 of the front lens frame 102, the display assembly 108, and the rear lens frame 104, respectively, are configured to enable alignment during coupling of the display assembly 108 with the front lens frame 102 and the rear lens frame 104 (e.g., enabling alignment during installation of the lens assembly to the frame of the augmented-reality glasses).

[0062] In some embodiments, the nasal-locating features 210, 212, and 214 of the front lens frame 102, the display assembly 108, and the rear lens frame 104, respectively, are configured to enable alignment during coupling of the display assembly 108 with the front lens frame 102 and the rear lens frame 104 (e.g., enabling alignment during installation of the lens assembly to the frame of the augmented-reality7glasses).

[0063] In some embodiments, the temple-locating features and the nasal-locating features (in conjunction with a fixturing component when assembled with the front lens frame 102 and the rear lens frame 104) restrict movement of the display assembly 108 in an XY direction. For example, the temple-locating features and the nasal-locating features restrict lateral movement of the display assembly 108 relative to the front lens frame 102 and / or the rear lens frame 104. In some embodiments, the front lens frame 102 and / or the rear lens frame 1 4 restrict movement of the display assembly in a Z direction. For example, the front lens frame 102 restricts forward movement of the display assembly 108, and the rear lens frame 104 restricts rearward movement of the display assembly 108.

[0064] In some embodiments, the temple-locating features and the nasal-locating features are in the same relative positions to each other for different lens frame(s). For example, the temple-locating features and the nasal-locating features are present on both the front lens frame 102 and the rear lens frame 104 (as show n in Figure 1A) and the front lens frame 103 and the rear lens frame 105 (as shown in Figure IB). In this example, the locating features are in the same relative positions such that they constrain the movement of the display assembly when mounted to a respective lens frame.

[0065] Figure 3 illustrates an example of a lens stack 107 of the display assembly, in accordance with some embodiments. In some embodiments, the lens stack 107 includes a second visual image distance (VID2) lens 302, an adhesive 304. a waveguide 306, an adhesive 324, an eye-tracking component 308 (e.g., an eye-tracking flexible circuit) that includeselectrical connectors 309 and 310, an adhesive 326, a bracket 311, an adhesive 328, a first visual image distance (VID1) glass lens 312, an adhesive 314, and a VID1 plastic lens 316.

[0066] In some embodiments, the VID1 lens(es) 312 and / or 316 adjust the image from the waveguide 306 so that the image appears a specified distance from a user, and the VID2 lens 302 counteracts the VID1 lens so that the worldview is not distorted (e.g., distorted by the VID1 lens).

[0067] In some embodiments, the VID2 lens 302, waveguide 306, VID1 glass lens 312, and / or VID1 plastic lens 316 include pin and slot systems for alignment of the aforementioned components. Further, the pin and slot system is configured to align the lens stack 107 with the front lens frame 102 and / or the rear lens frame 104 of the augmented-reality glasses.

[0068] In some embodiments, a display projector assembly is configured to couple to the lens stack 107. The display projector assembly 318 may couple directly to the waveguide 306 of the lens stack 107. The display projector assembly 318 is configured to provide an image (or other optical information) to the waveguide 306 that then displays the image. For example, the display projector assembly 318 provides an image to the waveguide 306 such that a user can view the image.

[0069] In some embodiments, the display projector assembly 318 includes a liquid cry stal on silicon display engine that generates light to produce the image that is projected into the waveguide 306. The waveguide 306 takes the projected image from one location (e.g., from the display projector assembly 318) and redirects the image to a user’s eye(s) via a plurality of mirrors (e g., glass components with partial mirrors).

[0070] In some embodiments, the lens stack 107 includes an active dimming component 320 (e.g., an active dimming flexible circuit). The active dimming component is configured to change transmissivity to at least increase contrast in the display image. The active dimming component can be electrochromic.

[0071] In some embodiments, the eye-tracking component 308 is configured to wrap around a frame of the augmented-reality glasses (e.g., the front lens frame 102 and / or the rear lens frame 104). For example, the eye-tracking component 308 includes a flexible circuit that includes a plurality of light emitting diodes (LEDs) that are configured to create glints on a user’s pupil. These glints are captured by one or more eye-tracking cameras and processed to determine a direction that a user is looking. The eye-tracking component 308 can include an eye-tracking driver (e.g., the eye-tracking flexible circuit includes a driver component for the plurality of LEDs and / or the one or more cameras). The eye-tracking component 308 can be adhered (e.g., via glue and / or other adhesives) to other components of the display assembly108. In some embodiments, the eye-tracking component 308 includes separate eye-tracking subcomponents (e.g., a first eye-tracking subcomponent with a first subset of LEDs and / or camera(s) and a second eye-tracking subcomponent with a second subset of LEDs and / or camera(s)).

[0072] In some embodiments, the bracket 311 includes flanges that are configured to improve drop reliability of the lens stack 107 and / or the augmented-reality glasses. Further, the bracket 311 can electrically couple to other components of the display assembly 108 (e.g., eyetracking component 308, display projector assembly 318, and / or other components of the display assembly 108) to provide grounding for those components.

[0073] In some embodiments, one or more of the adhesives 304, 314, 324, 326, and 328 are optically transparent such that an image generated by the display assembly and displayed at the waveguide is not degraded by the adhesives.

[0074] In some embodiments, the display projector assembly 318 is configured to thermally couple to the front lens frame 102 (as shown in Figure 1A) or front lens frame 103 (as shown in Figure IB) such that heat is transferred from the display projector assembly 318 to the front lens frame 102 or 103. Transferring the heat toward the front lens frame 102 or 103 increases user comfort (e.g., heat is radiated away from the user instead of toward a user). In some embodiments, graphite is used as a thermal interface between the display projector assembly 318 and a heat sink and / or radiator (e.g., the front lens frame 102 or 103). The graphite can be used with a pressure-sensitive adhesive.

[0075] Figure 4 illustrates a flow diagram of a method of manufacturing a pair of augmented-reality glasses, in accordance with some embodiments. In some embodiments, the various operations of the methods described herein are interchangeable and / or optional.

The display subassembly includes one or more lenses (e.g., lens stack 107, shown in Figures 1A and 3) and one or more electrical components (e.g., display projector assembly 106, disparity sensor assembly 110, eye-tracking component 308, and / or activedimming component 320 shown in Figures 1A and 3) that are configured to present an augmented-reality experience. The display subassembly further includes a modular mounting system (e.g., locating features 204 and 212 shown in Figure 2) that is configured to allow the display subassembly to be inserted into the lens frame and inserted into another lens frame of a second type that is different from the first type. For example, the modular mounting system is configured to allow the display subassembly to be inserted into a first pair of glasses and inserted into a second pair of glasses that is distinct from the first pair of glasses. The second pair of glasses can differ from the first pair of glasses in shape, size, and / or other physical parameters.

[0077] (A2) In some embodiments of Al, the method of manufacture of augmented-reality glasses further includes mounting 406 a second portion of the lens frame (e.g.. rear lens frame 104 shown in Figure 1A) to the first portion of the lens frame such that the display subassembly is secured within the pair of augmented-reality glasses. For example, the display subassembly is in between (e.g., sandwiched between) the first portion of the lens frame and the second portion of the lens frame.

[0078] (A3) In some embodiments of any of A1-A2, the display subassembly is configured in accordance with the display assembly corresponding to any of embodiments Bl-Bll.

[0079] (Bl) In accordance with some embodiments, a display assembly includes one or more lenses and one or more electrical components that are configured to present an augmented-reality experience at a pair of augmented-reality glasses. The display assembly further includes a modular mounting system that is configured to allow the display assembly to be inserted into a lens frame of a first type having a first shape and inserted into a lens frame of a second type having a second shape that is different from the first shape. For example, the modular mounting system is configured to allow the display assembly to be inserted into a first pair of glasses that is square and inserted into a second pair of glasses that is heart-shaped. The second pair of glasses can differ from the first pair of glasses in other ways, such as size, materials, and / or other physical parameters.

[0080] (B2) In some embodiments of Bl, the lens frame of the first type is configured to secure the first display assembly within a first pair of augmented-reality glasses and the lens frame of the second type is configured to secure the first display assembly within a second pair of augmented-reality glasses. The lens frame of the first type is distinct from the lens frame of the second type.

[0081] (B3) In some embodiments of any of B1-B2, the display assembly includes oneor more locating features (e.g., temple-locating features 202 and 204 and nasal-locating features 210 and 212 shown in Figure 2) that are configured to align the display assembly to the lens frame of the first type and configured to align the display assembly to the lens frame of the second type.

[0082] (B4) In some embodiments of any of B1-B3, the modular mounting system includes adhesive (e.g., a pressure-sensitive adhesive) configured to allow the display assembly to be coupled to the lens frame of the first type and coupled to the lens frame of the second type.

[0083] (B5) In some embodiments of any of B1-B4, the display assembly includes a display projection device (e.g., display projector assembly 318 shown in Figure 3, such as a liquid crystal on silicon (LCoS) based display engine), a waveguide (e.g., waveguide 306 shown in Figure 3), a first lens (e.g., VID1 lens(es) 312 and / or 316 shown in Figure 3), a second lens (e.g., VID2 lens 302 shown in Figure 3), and an eye-tracking device (e.g., eye-tracking component 308 shown in Figure 3). In some embodiments, the waveguide is a geometric reflective waveguide, the first lens is a plano-concave lens, and the second lens is a planoconvex lens. The first lens and the second lens can be configured such that the world-view through a combination of the two lenses is minimally or not distorted. The eye-tracking device includes a plurality of LEDs and one or more cameras to capture reflections (e.g., glints) of the light emitted from the plurality of LEDs from a user’s pupil.

[0084] (B6) In some embodiments of any of B5. the display projection device is configured to be coupled to the lens frame of the first type and the lens frame of the second type via an adhesive that is configured to dampen vibrations from a respective lens frame to the display projection device.

[0085] (B7) In some embodiments of any of B5-B6, the display projection device is configured to be thermally coupled to the lens frame of the first type and the lens frame of the second type via a thermally conductive material to transfer heat generated by the display projection device to a respective lens frame.

[0086] (B8) In some embodiments of any of B5-B7, the display projection device is electrically coupled to additional components of the augmented-reality glasses, such as one or more batteries, cameras, or sensors via aflexible circuit (e g., first connector 112 and / or second connector 114 shown in Figure 1A). Examples of sensors include disparity sensors, inertial measurement units, geolocation sensors, temperature sensors, and / or other types of sensors.

[0087] (B9) In some embodiments of any of B1-B8, the display assembly is a first display assembly that includes a second display assembly distinct from the first displayassembly (e.g., the right display assembly 107 shown in Figure 1A). The second display assembly (e.g.. the left display assembly shown in Figure 1A) includes one or more lenses of the second display assembly and one or more electronic components of the second display assembly that are configured to present an augmented-reality experience at the pair of augmented-reality glasses. The second display assembly also includes a modular mounting system of the second display assembly configured to allow the second display assembly to be inserted into the lens frame of a first type and inserted into the lens frame of a second type.

[0088] In some embodiments, the first portion of the lens frame of the first type or the second type is configured to be proximate to a user’s left eye, and the second portion of the lens frame of the first type or the second type is configured to be proximate to the user’s right eye when respective augmented-reality glasses are donned. As such, a first display assembly that is inserted into the first portion of the lens frame of the first type or the second type is within the viewing region of the user’s left eye when the respective augmented-reality glasses are donned, and a second display assembly that is inserted into the second portion of the lens frame of the first type or the second type is within the viewing region of the user’s right eye when the respective augmented-reality- glasses are donned.

The disparity sensing device is configured detect disparity between the first lens assembly and the second lens assembly based on visual information received from the first display assembly and the second display assembly.

[0090] (C 1) In accordance with some embodiments, a pair of augmented-reality’ glasses is configured corresponding to any of B 1 -B 10.

[0091] (DI) In accordance with some embodiments, a display subassembly of a pair of augmented-reality glasses is configured corresponding to any of Bl -BIO.Example Extended-Reality Systems

[0092] Figures 5 A, 5B, 5C-1, and 5C-2 illustrate example XR systems that include AR and MR systems, in accordance with some embodiments. Figure 5A shows a first XR system 500a and first example user interactions using a wrist-wearable device 526, a head-wearable device (e.g., AR device 528), and / or an HIPD 542. Figure 5B shows a second XR system 500b and second example user interactions using a wrist-wearable device 526, an AR device 528, and / or an HIPD 542. Figures 5C-1 and 5C-2 show a third MR system 500c and third example user interactions using a wrist-wearable device 526, a head-wearable device (e.g., an MR device such as a VR device), and / or an HIPD 542. As the skilled artisan will appreciate uponreading the descriptions provided herein, the above-example AR and MR systems (described in detail below) can perform various functions and / or operations.

[0093] The wrist-wearable device 526, the head-wearable devices, and / or the HIPD 542 can communicatively couple via a network 525 (e.g., cellular, near field, Wi-Fi, personal area network, and / or wireless LAN). Additionally, the wrist-wearable device 526, the headwearable device, and / or the HIPD 542 can also communicatively couple with one or more servers 530, computers 540 (e.g., laptops, computers), mobile devices 550 (e.g., smartphones, tablets), and / or other electronic devices via the network 525 (e.g., cellular, near field, Wi-Fi, personal area network, and / or wireless LAN). Similarly, a smart textile-based garment, when used, can also communicatively couple with the wrist-wearable device 526. the head-wearable device(s), the HIPD 542, the one or more servers 530, the computers 540, the mobile devices 550, and / or other electronic devices via the network 525 to provide inputs.

[0094] Turning to Figure 5A, a user 502 is shown wearing the wrist-wearable device 526 and the AR device 528 and having the HIPD 542 on their desk. The w rist-w earable device 526, the AR device 528, and the HIPD 542 facilitate user interaction with an AR environment. In particular, as shown by the first AR system 500a, the wrist-wearable device 526, the AR device 528, and / or the HIPD 542 cause presentation of one or more avatars 504, digital representations of contacts 506, and virtual objects 508. As discussed below, the user 502 can interact with the one or more avatars 504, digital representations of the contacts 506, and virtual objects 508 via the wrist- wearable device 526, the AR device 528, and / or the HIPD 542. In addition, the user 502 is also able to directly view physical objects in the environment, such as a physical table 529, through transparent lens(es) and waveguide(s) of the AR device 528. Alternatively, an MR device could be used in place of the AR device 528 and a similar user experience can take place, but the user would not be directly viewing physical objects in the environment, such as the table 529, and would instead be presented with a virtual reconstruction of the table 529 produced from one or more sensors of the MR device (e.g., an outward-facing camera capable of recording the surrounding environment).

[0095] The user 502 can use any of the wrist-wearable device 526, the AR device 528 (e.g., through physical inputs at the AR device and / or built-in motion tracking of a user’s extremities), a smart-textile garment, an externally mounted extremity tracking device, the HIPD 542 to provide user inputs, etc. For example, the user 502 can perform one or more hand gestures that are detected by the wrist-wearable device 526 (e.g., using one or more EMG sensors and / or IMUs built into the wrist-wearable device) and / or AR device 528 (e.g., using one or more image sensors or cameras) to provide a user input. Alternatively, or additionally,the user 502 can provide a user input via one or more touch surfaces of the wrist- wearable device 526, the AR device 528, and / or the HIPD 542, and / or voice commands captured by a microphone of the wrist-wearable device 526, the AR device 528, and / or the HIPD 542. The wrist-wearable device 526, the AR device 528, and / or the HIPD 542 include an artificially intelligent digital assistant to help the user in providing a user input (e.g., completing a sequence of operations, suggesting different operations or commands, providing reminders, and / or confirming a command). For example, the digital assistant can be invoked through an input occurring at the AR device 528 (e.g., via an input at a temple arm of the AR device 528). In some embodiments, the user 502 can provide a user input via one or more facial gestures and / or facial expressions. For example, cameras of the wrist-wearable device 526, the AR device 528, and / or the HIPD 542 can track the user 502's eyes for navigating a user interface.

[0096] The wrist- wearable device 526, the AR device 528, and / or the HIPD 542 can operate alone or in conjunction to allow the user 502 to interact with the AR environment. In some embodiments, the HIPD 542 is configured to operate as a central hub or control center for the wrist-wearable device 526, the AR device 528, and / or another communicatively coupled device. For example, the user 502 can provide an input to interact with the AR environment at any of the wrist- wearable device 526, the AR device 528, and / or the HIPD 542, and the HIPD 542 can identify one or more back-end and front-end tasks to cause the performance of the requested interaction and distribute instructions to cause the performance of the one or more back-end and front-end tasks at the wrist-wearable device 526, the AR device 528, and / or the HIPD 542. In some embodiments, a back-end task is a background-processing task that is not perceptible by the user (e.g., rendering content, decompression, compression, and / or application-specific operations), and a front-end task is a user-facing task that is perceptible to the user (e.g., presenting information to the user and / or providing feedback to the user). The HIPD 542 can perform the back-end tasks and provide the wrist-wearable device 526 and / or the AR device 528 operational data corresponding to the performed back-end tasks such that the wrist-wearable device 526 and / or the AR device 528 can perform the front-end tasks. In this way, the HIPD 542, which has more computational resources and greater thermal headroom than the wrist-wearable device 526 and / or the AR device 528, performs computationally intensive tasks and reduces the computer resource utilization and / or power usage of the wrist-wearable device 526 and / or the AR device 528.

[0097] In the example shown by the first AR system 500a, the HIPD 542 identifies one or more back-end tasks and front-end tasks associated with a user request to initiate an AR video call with one or more other users (represented by the avatar 504 and the digitalrepresentation of the contact 506) and distributes instructions to cause the performance of the one or more back-end tasks and front-end tasks. In particular, the HIPD 542 performs back-end tasks for processing and / or rendering image data (and other data) associated with the AR video call and provides operational data associated with the performed back-end tasks to the AR device 528 such that the AR device 528 performs front-end tasks for presenting the AR video call (e.g., presenting the avatar 504 and the digital representation of the contact 506).

[0098] In some embodiments, the HIPD 542 can operate as a focal or anchor point for causing the presentation of information. This allows the user 502 to be generally aware of where information is presented. For example, as shown in the first AR system 500a, the avatar 504 and the digital representation of the contact 506 are presented above the HIPD 542. In particular, the HIPD 542 and the AR device 528 operate in conjunction to determine a location for presenting the avatar 504 and the digital representation of the contact 506. In some embodiments, information can be presented within a predetermined distance from the HIPD 542 (e.g., within five meters). For example, as shown in the first AR system 500a, virtual object 508 is presented on the desk some distance from the HIPD 542. Similar to the above example, the HIPD 542 and the AR device 528 can operate in conjunction to determine a location for presenting the virtual object 508. Alternatively, in some embodiments, presentation of information is not bound by the HIPD 542. More specifically, the avatar 504, the digital representation of the contact 506, and the virtual object 508 do not have to be presented within a predetermined distance of the HIPD 542. While an AR device 528 is described working with an HIPD, an MR headset can be interacted with in the same way as the AR device 528.

[0099] User inputs provided at the wrist-wearable device 526, the AR device 528, and / or the HIPD 542 are coordinated such that the user can use any device to initiate, continue, and / or complete an operation. For example, the user 502 can provide a user input to the AR device 528 to cause the AR device 528 to present the virtual object 508 and, while the virtual object 508 is presented by the AR device 528, the user 502 can provide one or more hand gestures via the wrist- wearable device 526 to interact and / or manipulate the virtual object 508. While an AR device 528 is described working with a wrist-wearable device 526, an MR headset can be interacted with in the same way as the AR device 528.Integration of Artificial Intelligence with XR Systems

[0100] Figure 5A illustrates an interaction in which an artificially intelligent virtual assistant can assist in requests made by a user 502. The Al virtual assistant can be used to complete open-ended requests made through natural language inputs by a user 502. For example, in Figure 5A, the user 502 makes an audible request 544 to summarize theconversation and then share the summarized conversation with others in the meeting. In addition, the Al virtual assistant is configured to use sensors of the XR system (e.g., cameras of an XR headset, microphones, and various other sensors of any of the devices in the system) to provide contextual prompts to the user for initiating tasks.

[0101] Figure 5A also illustrates an example neural network 552 used in Artificial Intelligence applications. Uses of Artificial Intelligence (Al) are varied and encompass many different aspects of the devices and systems described herein. Al capabilities cover a diverse range of applications and deepen interactions between the user 502 and user devices (e.g., the AR device 528, an MR device 532, the HIPD 542, and / or the wrist-wearable device 526). The Al discussed herein can be derived using many different training techniques. While the primary Al model example discussed herein is a neural network, other Al models can be used. Nonlimiting examples of Al models include artificial neural networks (ANNs), deep neural networks (DNNs), convolution neural networks (CNNs), recurrent neural networks (RNNs), large language models (LLMs), long short-term memory' networks, transformer models, decision trees, random forests, support vector machines, k-nearest neighbors, genetic algorithms, Markov models, Bayesian networks, fuzzy logic systems, and deep reinforcement learnings, etc. The Al models can be implemented at one or more of the user devices, and / or any other devices described herein. For devices and systems herein that employ multiple Al models, different models can be used depending on the task. For example, for a naturallanguage artificially intelligent virtual assistant, an LLM can be used and for the object detection of a physical environment, a DNN can be used instead.

[0102] In another example, an Al virtual assistant can include many different Al models, and based on the user’s request, multiple Al models can be employed (concurrently, sequentially or a combination thereof). For example, an LLM-based Al model can provide instructions for helping a user follow a recipe and the instructions can be based in part on another Al model that is derived from an ANN, a DNN, an RNN, etc., that is capable of discerning what part of the recipe the user is on (e.g., object and scene detection).

[0103] As Al training models evolve, the operations and experiences described herein could potentially be performed with different models other than those listed above, and a person skilled in the art would understand that the list above is non-limiting.

[0104] A user 502 can interact with an Al model through natural language inputs captured by a voice sensor, text inputs, or any other input modality that accepts natural language and / or a corresponding voice sensor module. In another instance, input is provided by tracking the eye gaze of a user 502 via a gaze tracker module. Additionally, the Al modelcan also receive inputs beyond those supplied by a user 502. For example, the Al can generate its response further based on environmental inputs (e.g., temperature data, image data, video data, ambient light data, audio data, GPS location data, inertial measurement (i. e. , user motion) data, pattern recognition data, magnetometer data, depth data, pressure data, force data, neuromuscular data, heart rate data, temperature data, and / or sleep data) captured in response to a user request by various types of sensors and / or their corresponding sensor modules. The sensors’ data can be retrieved entirely from a single device (e.g., AR device 528) or from multiple devices that are in communication with each other (e.g., a system that includes at least two of an AR device 528, an MR device 532, the HIPD 542, the wrist-wearable device 526, etc.). The Al model can also access additional information (e.g., one or more servers 530, the computers 540, the mobile devices 550, and / or other electronic devices) via a network 525.

[0105] A non-limiting list of Al-enhanced functions includes but is not limited to image recognition, speech recognition (e.g., automatic speech recognition), text recognition (e.g., scene text recognition), pattern recognition, natural language processing and understanding, classification, regression, clustering, anomaly detection, sequence generation, content generation, and optimization. In some embodiments, Al-enhanced functions are fully or partially executed on cloud-computing platforms communicatively coupled to the user devices (e.g., the AR device 528, an MR device 532, the HIPD 542, and / or the wrist-wearable device 526) via the one or more networks. The cloud-computing platforms provide scalable computing resources, distributed computing, managed Al services, interference acceleration, pre-trained models, APIs and / or other resources to support comprehensive computations required by the Al-enhanced function.

[0106] Example outputs stemming from the use of an Al model can include natural language responses, mathematical calculations, charts displaying information, audio, images, videos, texts, summaries of meetings, predictive operations based on environmental factors, classifications, pattern recognitions, recommendations, assessments, or other operations. In some embodiments, the generated outputs are stored on local memories of the user devices (e.g., the AR device 528, an MR device 532, the HIPD 542, and / or the wrist-wearable device 526), storage options of the external devices (servers, computers, mobile devices, etc.), and / or storage options of the cloud-computing platforms.

[0107] The Al -based outputs can be presented across different modalities (e.g., audiobased, visual-based, haptic-based, and any combination thereof) and across different devices of the XR system described herein. Some visual-based outputs can include the displaying of information on XR augments of an XR headset, and / or user interfaces displayed at a wrist-wearable device, laptop device, mobile device, etc. On devices with or without displays (e.g., HIPD 542), haptic feedback can provide information to the user 502. An Al model can also use the inputs described above to determine the appropriate modality and device(s) to present content to the user (e.g., a user walking on a busy road can be presented with an audio output instead of a visual output to avoid distracting the user 502).Example Augmented Reality Interaction

[0108] Figure 5B shows the user 502 wearing the wrist-wearable device 526 and the AR device 528 and holding the HIPD 542. In the second AR system 500b, the wrist-wearable device 526, the AR device 528, and / or the HIPD 542 are used to receive and / or provide one or more messages to a contact of the user 502. In particular, the wrist- wearable device 526, the AR device 528, and / or the HIPD 542 detect and coordinate one or more user inputs to initiate a messaging application and prepare a response to a received message via the messaging application.

[0109] In some embodiments, the user 502 initiates, via a user input, an application on the wrist-wearable device 526, the AR device 528. and / or the HIPD 542 that causes the application to initiate on at least one device. For example, in the second AR system 500b, the user 502 performs a hand gesture associated with a command for initiating a messaging application (represented by messaging user interface 512). The wrist- wearable device 526 detects the hand gesture and, based on a determination that the user 502 is wearing the AR device 528, causes the AR device 528 to present a messaging user interface 512 of the messaging application. The AR device 528 can present the messaging user interface 512 to the user 502 via its display (e.g., as shown by user 502’s field of view 510). In some embodiments, the application is initiated and can be run on the device (e.g., the wrist-wearable device 526, the AR device 528, and / or the HIPD 542) that detects the user input to initiate the application, and the device provides another device operational data to cause the presentation of the messaging application. For example, the wrist-wearable device 526 can detect the user input to initiate a messaging application, initiate and run the messaging application, and provide operational data to the AR device 528 and / or the HIPD 542 to cause presentation of the messaging application. Alternatively, the application can be initiated and run at a device other than the device that detected the user input. For example, the wrist-wearable device 526 can detect the hand gesture associated with initiating the messaging application and cause the HIPD 542 to run the messaging application and coordinate the presentation of the messaging application.

[0110] Further, the user 502 can provide a user input provided at the wrist- earabledevice 526, the AR device 528, and / or the HIPD 542 to continue and / or complete an operation initiated at another device. For example, after initiating the messaging application via the wristwearable device 526 and while the AR device 528 presents the messaging user interface 512, the user 502 can provide an input at the HIPD 542 to prepare a response (e.g., shown by the swipe gesture performed on the HIPD 542). The user 502’s gestures performed on the HIPD 542 can be provided and / or displayed on another device. For example, the user 502's swipe gestures performed on the HIPD 542 are displayed on a virtual keyboard of the messaging user interface 512 displayed by the AR device 528.[OHl] In some embodiments, the wrist-wearable device 526, the AR device 528, the HIPD 542, and / or other communicatively coupled devices can present one or more notifications to the user 502. The notification can be an indication of a new message, an incoming call, an application update, a status update, etc. The user 502 can select the notification via the wrist-wearable device 526, the AR device 528, or the HIPD 542 and cause presentation of an application or operation associated with the notification on at least one device. For example, the user 502 can receive a notification that a message was received at the wrist-wearable device 526, the AR device 528, the HIPD 542, and / or another communicatively coupled device and provide a user input at the wrist-wearable device 526, the AR device 528, and / or the HIPD 542 to review the notification, and the device detecting the user input can cause an application associated with the notification to be initiated and / or presented at the wrist-wearable device 526, the AR device 528, and / or the HIPD 542.

[0112] While the above example describes coordinated inputs used to interact with a messaging application, the skilled artisan will appreciate upon reading the descriptions that user inputs 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 528 can present to the user 502 game application data and the HIPD 542 can use a controller to provide inputs to the game. Similarly, the user 502 can use the wrist-wearable device 526 to initiate a camera of the AR device 528, and the user can use the wrist-wearable device 526, the AR device 528, and / or the HIPD 542 to manipulate the image capture (e.g., zoom in or out, and / or apply filters) and capture image data.

[0113] While an AR device 528 is shown being capable of certain functions, it is understood that an AR device can be an AR device with varying functionalities based on costs and market demands. For example, an AR device can include a single output modality such as an audio output modality. In another example, the AR device can include a low-fidelity displayas one of the output modalities, where simple information (e.g., text and / or low-fidelity images / video) is capable of being presented to the user. In yet another example, the AR device can be configured with face-facing light emitting diodes (LEDs) configured to provide a user with information, e.g., an LED around the right-side lens can illuminate to notify the w earer to turn right while directions are being provided or an LED on the left-side lens can illuminate to notify the wearer to turn left while directions are being provided. In another embodiment, the AR device can include an outward-facing projector such that information (e.g., text information and / or media) can be displayed on the palm of a user’s hand or another suitable surface (e.g., a table or a whiteboard). In yet another embodiment, information can also be provided by locally dimming portions of a lens to emphasize portions of the environment in which the user’s attention should be directed. Some AR devices can present AR augments either monocularly or binocularly (e.g., an AR augment can be presented at only a single display associated with a single lens as opposed to presenting an AR augmented at both lenses to produce a binocular image). In some instances an AR device capable of presenting AR augments binocularly can optionally display AR augments monocularly as well (e.g., for power-saving purposes or other presentation considerations). These examples are non-exhaustive, and features of one AR device described above can be combined with features of another AR device described above. While features and experiences of an AR device have been described generally in the preceding sections, it is understood that the described functionalities and experiences can be applied in a similar manner to an MR headset, which is described below in the following sections.Example Mixed Reality Interaction

[0114] Turning to Figures 5C-11 and 5C-2, the user 502 is shown wearing the wristwearable device 526 and an MR device 532 (e.g., a device capable of providing either an entirely VR experience or an MR experience that displays object(s) from a physical environment at a display of the device) and holding the HIPD 542. In the third AR system 500c, the wrist-wearable device 526, the MR device 532, and / or the HIPD 542 are used to interact within an MR environment, such as a VR game or other MR / VR application. While the MR device 532 presents a representation of a VR game (e.g., first MR game environment 520) to the user 502, the wrist-wearable device 526. the MR device 532, and / or the HIPD 542 detect and coordinate one or more user inputs to allow" the user 502 to interact with the VR game.

[0115] In some embodiments, the user 502 can provide a user input via the wristwearable device 526, the MR device 532, and / or the HIPD 542 that causes an action in a corresponding MR environment. For example, the user 502 in the third MR system 500c(shown in Figure 5C-1) raises the HIPD 542 to prepare for a swing in the first MR game environment 520. The MR device 532. responsive to the user 502 raising the HIPD 542, causes the MR representation of the user 522 to perform a similar action (e.g., raise a virtual object, such as a virtual sword 524). In some embodiments, each device uses respective sensor data and / or image data to detect the user input and provide an accurate representation of the user 502’s motion. For example, image sensors (e.g., SLAM cameras or other cameras) of the HIPD 542 can be used to detect a position of the HIPD 542 relative to the user 502’s body such that the virtual object can be positioned appropriately within the first MR game environment 520, sensor data from the wrist-w earable device 526 can be used to detect a velocity at which the user 502 raises the HIPD 542 such that the MR representation of the user 522 and the virtual sword 524 are synchronized with the user 502's movements, and image sensors of the MR device 532 can be used to represent the user 502’s body, boundary conditions, or real-world objects within the first MR game environment 520.

[0116] In Figure 5C-2, the user 502 performs a downward swing while holding the HIPD 542. The user 502’s downward swing is detected by the wrist-wearable device 526, the MR device 532, and / or the HIPD 542 and a corresponding action is performed in the first MR game environment 520. In some embodiments, the data captured by each device is used to improve the user’s experience within the MR environment. For example, sensor data of the wrist-wearable device 526 can be used to determine a speed and / or force at which the downward swing is performed and image sensors of the HIPD 542 and / or the MR device 532 can be used to determine a location of the swing and how it should be represented in the first MR game environment 520, which, in turn, can be used as inputs for the MR environment (e.g., game mechanics, which can use detected speed, force, locations, and / or aspects of the user 502’s actions to classify a user’s inputs (e.g., user performs a light strike, hard strike, critical strike, glancing strike, and / or miss) or calculate an output (e.g., amount of damage)).

[0117] Figure 5C-2 further illustrates that a portion of the physical environment Is reconstructed and displayed at a display of the MR device 532 while the MR game environment 520 is being displayed. In this instance, a reconstruction of the physical environment 546 is displayed in place of a portion of the MR game environment 520 when obj ect(s) in the physical environment are potentially in the path of the user (e.g., a collision with the user and an object in the physical environment are likely). Thus, this example MR game environment 520 includes (i) an immersive VR portion 548 (e.g., an environment that does not have a corollary counterpart in a nearby physical environment) and (ii) a reconstruction of the physical environment 546 (e.g., table 550 and cup 552). While the example shown here is an MRenvironment that shows a reconstruction of the physical environment to avoid collisions, other uses of reconstructions of the physical environment can be used, such as defining features of the virtual environment based on the surrounding physical environment (e.g., a virtual column can be placed based on an object in the surrounding physical environment (e.g., a tree)).

[0118] While the wrist-wearable device 526, the MR device 532, and / or the HIPD 542 are described as detecting user inputs, in some embodiments, user inputs are detected at a single device (with the single device being responsible for distributing signals to the other devices for performing the user input). For example, the HIPD 542 can operate an application for generating the first MR game environment 520 and provide the MR device 532 with corresponding data for causing the presentation of the first MR game environment 520, as well as detect the user 502’s movements (while holding the HIPD 542) to cause the performance of corresponding actions within the first MR game environment 520. Additionally or alternatively, in some embodiments, operational data (e.g., sensor data, image data, application data, device data, and / or other data) of one or more devices is provided to a single device (e.g., the HIPD 542) to process the operational data and cause respective devices to perform an action associated with processed operational data.

[0119] In some embodiments, the user 502 can wear a wrist-wearable device 526, wear an MR device 532, wear smart textile based garments 538 (e.g., wearable haptic gloves), and / or hold an HIPD 542 device. In this embodiment, the wrist-wearable device 526, the MR device 532, and / or the smart textile-based garments 538 are used to interact within an MR environment (e.g., any AR or MR system described above in reference to Figures 5A-5B). While the MR device 532 presents a representation of an MR game (e.g., second MR game environment 520) to the user 502, the wrist-wearable device 526, the MR device 532, and / or the smart textilebased garments 538 detect and coordinate one or more user inputs to allow the user 502 to interact with the MR environment.

[0120] In some embodiments, the user 502 can provide a user input via the wristwearable device 526, an HIPD 542, the MR device 532, and / or the smart textile-based garments 538 that causes an action in a corresponding MR environment. In some embodiments, each device uses respective sensor data and / or image data to detect the user input and provide an accurate representation of the user 502’s motion. While four different input devices are shown (e.g., a wrist-wearable device 526, an MR device 532, an HIPD 542, and a smart textile-based garment 538), each one of these input devices entirely on its own can provide inputs for fully interacting with the MR environment. For example, the wrist- wearable device can provide sufficient inputs on its own for interacting with the MR environment. In some embodiments, ifmultiple input devices are used (e.g., a wrist-wearable device and the smart textile-based garment 538), sensor fusion can be utilized to ensure that inputs are correct. While multiple input devices are described, it is understood that other input devices can be used in conjunction or on their own instead, such as but not limited to external motion-tracking cameras, other wearable devices fitted to different parts of a user, apparatuses that allow for a user to experience walking in an MR environment while remaining substantially stationary in the physical environment, etc.

[0121] As described above, the data captured by each device is used to improve the user’s experience within the MR environment. Although not shown, the smart textile-based garments 538 can be used in conjunction with an MR device and / or an HIPD 542.

[0122] While some experiences are described as occurring on an AR device and other experiences are described as occurring on an MR device, one skilled in the art would appreciate that experiences can be ported over from an MR device to an AR device, and vice versa.
