Technical Field

[0002] This disclosure generally relates to asymmetric multi-battery architectures for head-mounted wearable devices and power management techniques thereof. Background Technology

[0003] The battery designs used in most wearable devices, including head-mounted devices, typically utilize symmetrical battery designs. However, as additional electronics are added to smart glasses, extended reality (XR) head-mounted displays, and other head-mounted wearables, space constraints mean that symmetrical battery designs will become unsuitable and / or will require designers to sacrifice some functionality of these new head-mounted devices. Furthermore, as more power-intensive features are added to such head-mounted devices, peak power consumption periods can cause system shutdowns and degrade the user experience.

[0004] Therefore, it is necessary to address one or more of the challenges mentioned above. A brief overview of the solutions to these problems is described below. Summary of the Invention

The first battery is configured to be housed within the first temple portion and has a first shape. The second battery is configured to be housed within the second temple portion and has a second shape different from the first shape. One or more programs include instructions for performing a plurality of operations. The operations include: during a first time period and based on determining that the capacity of the first battery is sufficient to power electronic components in the first temple portion, supplying power from the first battery to the electronic components in the first temple portion.

[0025] Numerous details are described herein to provide a thorough understanding of the exemplary embodiments illustrated in the accompanying drawings. However, some embodiments may be practiced without many of these specific details, and the scope of the claims is limited to those features and aspects specifically recited in the claims. Furthermore, well-known processes, components, and materials are not necessarily described exhaustively to avoid obscuring relevant aspects of the embodiments described herein.

[0026] Overview Embodiments of this disclosure may include different types of extended reality (XR), or a combination of different types of XR, such as mixed reality (MR) systems and augmented reality (AR) systems. As described herein, MR and AR are any overlay of functional and / or sensorily detectable presentations provided by MR and AR systems within a user's physical environment. Such MR may include and / or represent virtual reality (VR), in which at least some aspects of the surrounding environment are reconstructed in the virtual environment (e.g., displaying a virtual reconstruction of physical objects in the physical environment to avoid collisions between the user and physical objects in the surrounding physical environment). In the case of MR, the surrounding environment presented through the display is captured by one or more sensors configured to capture the surrounding environment (e.g., camera sensors, time-of-flight (ToF) sensors). While the wearer of an MR headset can see full details of the surrounding environment, what they see is an environmental reconstruction reproduced using data from one or more sensors (i.e., the user cannot directly see physical objects). MR headsets may also forgo displaying a reconstruction of objects in the physical environment, thereby providing the user with a fully VR experience. On the other hand, AR systems provide an experience in which information is provided, for example, by using waveguides and combining them with one or more transparent or translucent waveguides and / or lenses through an AR head-mounted viewer to directly view at least some of the surrounding environment. Throughout this application, the term "extended reality (XR)" is used as a general term encompassing both AR and MR. Furthermore, this application sometimes uses "head-wearable device" or "head-mounted viewer" as a generic term to cover XR head-mounted viewers such as AR head-mounted viewers and MR head-mounted viewers.

[0027] As described above, the MR environment described herein may include, but is not limited to, non-immersive VR environments, semi-immersive VR environments, and fully immersive VR environments. As described above, AR environments may include marker-based AR environments, markerless AR environments, location-based AR environments, and projection-based AR environments. The above description is not exhaustive, and any other environment that allows intentional ambient lighting to pass through to reach the user will fall within the scope of AR, while any other environment that does not allow intentional ambient lighting to pass through to reach the user will fall within the scope of MR.

[0028] 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 (e.g., stereoscopic video that creates a three-dimensional effect for the viewer). Furthermore, AR and MR can be associated with applications, products, accessories, services, or some combination thereof, for example, for creating content in an AR or MR environment and / or otherwise using it in an AR or MR environment (e.g., performing activities in an AR or MR environment).

[0029] The interactions with these AR and MR environments described in this article can occur in several different modes, and the resulting outputs can also occur across multiple different modes. In one example of an AR or MR system, a user can make an air swipe gesture to skip a song via an application programming interface (API) provided by a song that is played, for example, at a home speaker.

[0030] As described herein, gestures can include air gestures, surface contact gestures, and / or other gestures that can be detected and determined based on: single-hand movement (e.g., a single-hand gesture made by a user's hand, detected by one or more sensors of a wearable device (e.g., an electromyography (EMG) and / or an inertial measurement unit (IMU) of a wrist wearable device and / or one or more sensors included in a smart textile wearable device), and / or the single-hand gesture is detected by image data captured by an imaging device of the wearable device (e.g., a camera of a head wearable device, an external tracking camera positioned in the surrounding environment). "Air" generally includes gestures in which a portion of a user's hand does not contact a surface, object, or electronic device (e.g., a head wearable device or other communication-coupled device, such as a wrist wearable device); in other words, the gesture is made in open space in 3D space and does not contact a surface, object, or electronic device. More generally, surface contact gestures (contacts on surfaces, objects, user body parts, or electronic devices) are also considered, in which contact (or intention to contact) is detected at the surface (e.g., on a table, on the user's hand or another finger, on the user's leg, a sofa, or a steering wheel with a single or two-finger tap). The various gestures disclosed herein can be detected using image data and / or sensor data (e.g., neuromuscular signals sensed by one or more bioelectric sensors (e.g., EMG sensors) or other types of data from other sensors (e.g., proximity sensors, ToF sensors, IMU sensors, capacitive sensors, strain sensors) detected by wearable devices worn by the user and / or other electronic devices owned by the user (e.g., smartphones, laptops, imaging devices, intermediate devices, and / or other devices described herein).

[0031] The input modes described above can be diverse and depend on the user experience. For example, in interactions using a wrist-worn wearable device, a user can provide input using air gestures or surface contact gestures detected by the neuromuscular signal sensors of the wrist-worn wearable device. In the absence of a wrist-worn wearable device, alternative and fully interchangeable input modes can be used, such as one or more cameras located on a head-mounted viewer or elsewhere to detect air gestures or surface contact gestures, or input at an intermediate processing device (e.g., via physical input components such as buttons and touchpads). These different input modes can be interchanged based on the desired user experience, portability, and / or product feature set (e.g., low-cost products may not include a handheld tracking camera).

[0032] Different inputs result in different outputs. For example, an air gesture input detected by a camera on a head-mounted wearable device can cause the output to occur at the head-mounted wearable device or to control another electronic device different from the head-mounted wearable device. In another example, input detected using data from a neuromuscular signal sensor can also cause the output to occur at the head-mounted wearable device or to control another electronic device different from the head-mounted wearable device. While only a few examples have been described above, those skilled in the art will understand that different input patterns and different output patterns in response to the input are interchangeable.

In some embodiments, the first battery 222 and the second battery 227 are configured to power both the first electronics 224 and the second electronics 229. In some embodiments, the first battery 222 is a small battery (e.g., smaller than the first battery 202 and the second battery 207), and the second battery 227 is a large battery (e.g., larger than the first battery 202 and the second battery 207, such as...).

In the multi-asymmetric battery configuration, a first temple 230 (e.g., first temple 104) includes a first electronic component 234, a first battery 232a, and a second battery 232b, and a second temple 235 (e.g., second temple 106) includes a second electronic component 239 and a third battery 237. In some embodiments, the first battery 232a, the second battery 232b, and the third battery 237 are configured to power both the first electronic component 234 and the second electronic component 239. In some embodiments, the first battery 232a and the second battery 232b are small batteries (e.g., smaller than the first battery 202 and the second battery 207), and the third battery 237 is a large battery (e.g., larger than the first battery 202 and the second battery 207, such as...). Figure 2D (As shown). In some embodiments, the first electronic component 234 is smaller than the second electronic component 239, such as... Figure 2D As shown. In some embodiments, the respective arrangement, size, shape and / or weight of the first battery 232a, the second battery 232b and the first electronic component 234 and / or the third battery 237 and the second electronic component 239 are also configured such that the first temple 230 and the second temple 235 are balanced with each other, thereby improving the wearing experience.

[0051] Figure 2E Another asymmetric battery configuration according to some embodiments is illustrated. In this alternative asymmetric battery configuration, a first temple 240 (e.g., first temple 104) includes a first electronic component 244, a first battery 242, and an energy storage device 243, and a second temple 245 (e.g., second temple 106) includes a second electronic component 249 and a second battery 247. In some embodiments, the first battery 242, the second battery 247, and the energy storage device 243 are configured to power both the first electronic component 244 and the second electronic component 249. In some embodiments, the first battery 242 is a small battery (e.g., smaller than the first battery 202 and the second battery 207), and the second battery 247 is a large battery (e.g., larger than the first battery 202 and the second battery 207, such as...). Figure 2E (As shown). In some embodiments, the first electronic component 244 is smaller than the second electronic component 249, such as... Figure 2E As shown. In some embodiments, the respective arrangement, size, shape and / or weight of the first battery 242, energy storage device 243 and first electronic component 244 and / or second battery 247 and second electronic component 249 are also configured such that the first temple 240 and the second temple 245 are balanced with each other, thereby improving the wearing experience.

[0052] According to some embodiments, the head-mounted wearable device 100 is configured to operate from multiple batteries (e.g., reference 100). Figures 1 to 2EThe first battery 108, the second battery 110, the auxiliary battery, the first battery 202, etc. (described) supply multiple electronic components (e.g., reference) Figures 1 to 2E The first electronic component 112, the second electronic component 114, the additional electronic component, the first electronic component 204, etc., are described as being powered. In some embodiments, executable instructions stored in memory, when executed by a processor of the head-worn wearable device 100 and / or a processor of another device communicatively coupled to the head-worn wearable device 100, determine that power is supplied from a corresponding battery among a plurality of batteries to a corresponding electronic component among a plurality of electronic components. In some embodiments, this determination is based on which battery among the plurality of batteries is (physically and electronically) closest to the corresponding electronic component. For example, as... Figure 2E As shown, if the second electronic component 249 requires power, the second battery 247 will be determined to power the second electronic component 249 because the second battery 247 is closer to the second electronic component 249 (both physically and electronically) than the first battery 242. In some embodiments, this determination is based on which of the plurality of batteries has a larger available capacity (e.g., measured in watt-hours (Wh) and / or ampere-hours (Amp-hr)). For example, as Figure 2E As shown, if the second electronic component 249 requires power, and if the first battery 242 has a larger available capacity than the second battery 247, then the first battery 242 will be determined to supply power to the second electronic component 249. In some embodiments, a corresponding electronic component among a plurality of electronic components requires more power than a single battery among a plurality of batteries can provide. In this case, executable instructions determine that power is supplied from one or more corresponding batteries among a plurality of electronic components to the corresponding electronic component. For example, as... Figure 2E As shown, if the capacity of the first battery 242 is insufficient to power the first electronic component 244, both the first battery 242 and the second battery 247 will be determined to power the first electronic component 244. In some embodiments, determining to power a corresponding electronic component from a plurality of batteries and / or more than one corresponding battery is also based on: component information obtained from the plurality of electronic components indicating the corresponding power requirements of the plurality of electronic components; battery information obtained from the plurality of batteries indicating the corresponding available capacity of each of the plurality of batteries; user-specific power management settings; user behavior data; and / or thermal constraints of the plurality of batteries, the plurality of electronic components, the head wearable device 100 and / or any other component thereof.

[0053] In some embodiments, the energy storage device 243 is a high-capacity capacitor (e.g., a supercapacitor, ultracapacitor, tantalum capacitor, etc.) and / or another battery. The energy storage device 243 is configured to power the first electronic component 244, the second electronic component 249, and / or any other component of the head-worn wearable device 100. In some embodiments, the energy storage device 243 is configured to power the device to mitigate the risk of power shortage caused by voltage spikes and / or transient power demand spikes in the various electronic components of the head-worn wearable device 100. Examples of the energy storage device 243 that can power the device to mitigate the risk of power shortage include: (i) recording live video (image and audio data), (ii) making a video call with another user on another device, (iii) transmitting large data files via wireless communication components, (iv) performing calculations for a contextual AI program, and (v) performing visual translation of text captured by the camera of the head-worn wearable device 100.

[0054] Multiple batteries (e.g., reference) Figures 1 to 2E The respective capacities of the described first battery 108, second battery 110, auxiliary battery, first battery 202, etc., range from 100 megawatt-hours (mWh) to 4000 mWh. In some embodiments, the capacity of the larger battery is 0.5 to 10 times larger than that of the smaller battery. In some embodiments, the capacity of the larger battery ranges from 250 mWh to 2000 mWh, and the capacity of the smaller battery ranges from 125 mWh to 1000 mWh.

[0055] According to some embodiments, using an asymmetric battery configuration can present challenges when simultaneously charging two or more batteries in a head-worn wearable device 100. In some embodiments, each of the two or more batteries has a different battery capacity and / or different individual cell voltages, different charging times, different charging efficiencies, and / or different thermal considerations. Therefore, the charging voltage is determined based on headroom and the voltage of the largest battery among the two or more batteries. In some embodiments, the first individual cell voltage of a first battery among the two or more batteries is greater than the second individual cell voltage of a second battery among the two or more batteries, and the first battery will charge the second battery (cross-charging) if the discharge path of the smaller battery is uncontrolled. Cross-charging can result in undesirable power flows from one or more fully charged batteries to one or more partially charged batteries, leading to unnecessary power losses and unnecessary heat generation at the two or more batteries and / or multiple electronic components of the head-worn wearable device 100. Cross-charging can also result in unnecessary charge and discharge cycles, thereby reducing the corresponding cycle life of the two or more batteries. Furthermore, cross-charging may trigger the overcurrent protection mechanisms of two or more batteries, which could lead to unnecessary shutdown of the head-worn wearable device 100 and / or damage to those two or more batteries and / or multiple electronic components. Therefore, to prevent cross-charging, the discharge path of the smaller battery can be disabled when the charging voltage is lower than the first cell voltage, and enabled when the charging voltage is greater than or equal to the first cell voltage.

[0056] Figure 3A cross-charging prevention circuit 300, according to some embodiments, is shown to prevent a higher-voltage battery 310 from charging a lower-voltage battery 305. The higher-voltage battery 310 has a first voltage, and the lower-voltage battery 305 has a second voltage less than the first voltage. In some embodiments, the capacity of the lower-voltage battery 305 (e.g., between 125 mWh and 1000 mWh) is less than the capacity of the higher-voltage battery 310 (between 250 mWh and 2000 mWh). In some embodiments, the cross-charging prevention circuit 300 includes one or more electrical loads 312a to 312b (e.g., multiple electronic components of a head-mounted wearable device 100) that draw power from the higher-voltage battery 310 and / or the lower-voltage battery 305. In some embodiments, the cross-charging prevention circuit 300 includes one or more line impedances 314 generated by one or more wires electrically coupled to one or more electrical loads 312a to 312b, the higher-voltage battery 310, and / or the lower-voltage battery 305. The cross-charging prevention circuit 300 also includes a first charging path regulator 320a located between the lower voltage battery 305 and one or more electrical loads 312a to 312b, and a second charging path regulator 320b located between the higher voltage battery 310 and one or more electrical loads 312a to 312b. Each corresponding charging path regulator includes a charging transistor represented by a charging switch 324 and a charging body diode 322, and a discharging transistor represented by a discharging switch 328 and a discharging body diode 326. In some embodiments, the charging transistor and the discharging transistor are field-effect transmitters (FETs), such as metal-oxide-semiconductor field-effect transmitters (MOSFETs). In some embodiments, the charging transistor and the discharging transistor are controlled by a circuit controller (e.g., a processor of the head-worn wearable device 100 and / or a processor of another device communicatively coupled to the head-worn wearable device 100, as referenced). Figure 1 (As described) Control. The circuit controller can determine whether the lower voltage battery 305 is undergoing cross-charging by monitoring the current supplied to / from the lower voltage battery 305 and / or the current supplied to / from the higher voltage battery 310.

[0057] According to some embodiments, when the lower-voltage battery 305 does not have sufficient voltage to prevent cross-charging, the first charging path regulator 320a can enter a disable mode, a redirection mode, and / or a regulation mode to limit the cross-charging current supplied to the lower-voltage battery 305. In disable mode, the circuit controller turns off the charging transistor, preventing cross-charging current from being supplied to the lower-voltage battery 305. In redirection mode, the circuit controller turns on the charging transistor and turns off the discharging transistor. Therefore, the cross-charging current is limited by the forward voltage of the discharge diode 326. In regulation mode, the circuit controller turns on the charging transistor and turns on the discharging transistor. Therefore, the charging transistor becomes saturated, thereby limiting the cross-charging current to the saturation current of the charging transistor.

[0058] In some embodiments, the circuit controller can regulate the discharge current supplied by the lower-voltage battery 305 and / or the higher-voltage battery 310 to one or more electrical loads 312a to 312b by entering a regulated discharge mode. In the regulated discharge mode, the circuit controller turns on the charging transistor and the discharging transistor. Therefore, the discharging transistor becomes saturated, thereby limiting the discharge current to the saturation current of the discharging transistor. In some embodiments, before causing the first charging path regulator 320a to enter a disabled mode, a redirection mode, and / or a regulating mode, the circuit controller determines whether the higher-voltage battery 310 and / or the lower-voltage battery 305 is being charged (e.g., the head-mounted wearable device 100 is coupled to a charging device). If the higher-voltage battery 310 and / or the lower-voltage battery 305 is being charged, the circuit controller will not cause the first charging path regulator 320a to enter a disabled mode, a redirection mode, and / or a regulating mode.

[0059] In some embodiments, in response to determining that a higher-voltage battery 310 and / or a lower-voltage battery 305 among two or more batteries is being charged (e.g., the head-worn wearable device 100 is coupled to a charging device), the circuit controller obtains the larger battery voltage of the larger battery (e.g., with a capacity between 250 mWh and 2000 mWh) and the smaller battery voltage of the smaller battery (e.g., with a capacity between 125 mWh and 1000 mWh). In some embodiments, the initial charging voltage is the headroom voltage of the cross-charging prevention circuit 300. Based on determining that the smaller battery voltage is greater than the larger battery voltage, the circuit controller deactivates the discharge path of the smaller battery (if the smaller battery's discharge path is activated) and charges the larger battery with the charging voltage. Based on determining that the larger battery voltage is greater than the smaller battery voltage, the circuit controller activates the discharge path of the smaller battery (if the smaller battery's discharge path is deactivated) and charges both the larger and smaller batteries with the charging voltage. In some embodiments, the charging voltage is the sum of the larger battery voltage and the headroom voltage of the cross-charging prevention circuit 300. In some embodiments, when charging the larger and smaller batteries, the circuit controller monitors the voltages of the larger and smaller batteries to determine whether the voltage of the larger battery reaches and / or exceeds the voltage of the smaller battery, and / or whether the voltage of the smaller battery reaches and / or exceeds the voltage of the larger battery. Based on the determination that charging of the higher-voltage battery 310 and / or the lower-voltage battery 305 of the two or more batteries is no longer permitted (e.g., the head-worn wearable device 100 is decoupled from the charging device), the circuit controller activates the discharge path of the smaller battery (if the discharge path of the smaller battery has been deactivated).

[0060] Figure 4A and Figure 4B Two battery management techniques, according to some embodiments, are illustrated for managing the use of two or more batteries to power each of a plurality of electronic components in a head-worn wearable device. In some embodiments, the two battery management techniques may be performed alternately or simultaneously at the head-worn wearable device 100. In some embodiments, a processing device and / or a system-on-chip (SoC) component (e.g., according to one or more battery management techniques) controls two or more batteries to minimize energy waste, maximize energy efficiency, prevent undervoltage, and / or maximize the total battery life of the head-worn wearable device 100. In some embodiments, the two or more batteries include a larger battery (e.g., with a capacity between 250 mWh and 2000 mWh) and a smaller battery (e.g., with a capacity between 125 mWh and 1000 mWh).

The first method 400 includes using a smaller and a larger battery to power the device during low-load computing tasks (e.g., one or more low-load tasks performed at the head-mounted wearable device 100, such as streaming music online, making audio calls, sending messages, etc.), and using only the larger battery to power the device during high-load computing tasks (e.g., one or more low-load tasks performed at the head-mounted wearable device 100, such as capturing video, transmitting large amounts of data via Wi-Fi, performing computations for a contextual AI program). The first method 400 includes initiating one or more computing tasks at the head-mounted wearable device 100 (402), for example, in response to user input and / or instructions received from another device. The first method 400 also includes classifying the one or more computing tasks as low-load or high-load computing tasks (404). Based on the determination that the one or more computing tasks are high-load computing tasks, the first method 400 further includes: determining whether the battery power of the larger battery is sufficient to perform and / or enable the execution of the one or more computing tasks (406). In some embodiments, determining whether the battery power of the larger battery is sufficient to perform and / or enable the execution of the one or more computing tasks includes: determining whether the battery power of the larger battery meets a battery power threshold. In some embodiments, the battery power threshold is based on the one or more computing tasks and / or battery temperature. Based on the determination that the battery power of the larger battery is sufficient to perform and / or enable the execution of the one or more computing tasks, the first method 400 further includes: deactivating the discharge path of the smaller battery (408). The first method 400 further includes: allowing the larger battery to power the head-worn wearable device 100 while enabling the execution of the one or more computing tasks at the head-worn wearable device 100 and / or another device (410). The first method 400 further includes: determining whether the discharge path of the smaller battery is active (412). Based on the determination that the discharge path of the smaller battery is inactive, the first method 400 further includes: reactivating the discharge path of the smaller battery (414), and the first method 400 terminates (416).

[0062] Based on determining that one or more computing tasks are low-load computing tasks, the first method 400 further includes: allowing the larger and smaller batteries to power the head-mounted wearable device 100 while the computing tasks are being performed (410). The first method 400 further includes: determining whether the discharge path of the smaller battery is active (412). Based on determining that the discharge path of the smaller battery is active, the first method 400 terminates (416).

[0063] Based on determining that one or more computing tasks are high-load computing tasks and determining that the battery power of the larger battery is insufficient to execute and / or cause the execution of one or more computing tasks, the first method 400 further includes: preventing the head-mounted wearable device 100 from executing and / or causing the execution of one or more computing tasks (418). The first method 400 further includes: determining whether the discharge path of the smaller battery is active (412). Based on determining that the discharge path of the smaller battery is active, the first method 400 terminates (416).

[0064] Figure 4B A second battery management method (also referred to as a second method) 450 for managing two or more batteries of a head-mounted wearable device 100, according to some embodiments, is illustrated. The second method 450 includes using a task checklist to determine whether to use both a smaller battery and a larger battery, use only the smaller battery, use only the larger battery, and / or not use either battery to power one or more computational tasks performed at the head-mounted wearable device (e.g., one or more tasks performed at the head-mounted wearable device 100, such as listening to music online, making an audio call, sending a message, capturing video, transferring large amounts of data via Wi-Fi, performing computations for a contextual AI program, etc.). According to some embodiments, for each corresponding computational task and each corresponding battery temperature range, the task checklist includes a corresponding smaller battery power threshold and a corresponding larger battery power threshold. For example, the task checklist may include a first smaller battery power threshold and a first larger battery power threshold of 75% battery power and 25% battery power for performing and / or performing a live streaming task within a first battery temperature range of 20°C to 30°C; a second smaller battery power threshold and a second larger battery power threshold of 55% battery power and 20% battery power for performing and / or performing a live streaming task within a second battery temperature range of 10°C to 20°C; and a third smaller battery power threshold and a third larger battery power threshold of 35% battery power and 15% battery power for performing and / or performing a live streaming task within a third battery temperature range of 0°C to 10°C. Furthermore, the task checklist may include a fourth smaller battery power threshold of 50% battery power and a fourth larger battery power threshold of 30% battery power for performing and / or enabling the execution of Wi-Fi data transmission tasks within a first battery temperature range of 20°C to 30°C, and a fifth smaller battery power threshold of 35% battery power and a fifth larger battery power threshold of 25% battery power for performing and / or enabling the execution of Wi-Fi data transmission tasks within a second battery temperature range of 10°C to 20°C. In some embodiments, when the head-mounted wearable device 100 is idle (e.g., not performing and / or enabling the execution of any computing tasks), the task checklist may also include a corresponding smaller idle battery power threshold and a corresponding larger idle battery power threshold for each respective battery temperature range.

[0065] The second method 450 includes: initiating one or more computing tasks at the head-mounted wearable device 100 (452) (e.g., in response to user input and / or instructions received from another device). The second method 450 also includes: determining whether one or more computing tasks are permitted (454) based on a task checklist, the current battery temperature range, the current larger battery charge, and the current smaller battery charge (e.g., given one or more computing tasks and the current battery temperature, at least one of the smaller and larger batteries has a corresponding current battery charge greater than a corresponding battery charge threshold). Based on the determination that one or more computing tasks are permitted, the second method 450 further includes: selectively deactivating the discharge path of the smaller battery or the discharge path of the larger battery and / or abandoning the deactivation of the discharge path of the smaller battery and the discharge path of the larger battery based on a task checklist (e.g., deactivating the discharge path of the larger battery if the current larger battery charge is below a corresponding larger battery charge threshold, deactivating the discharge path of the smaller battery if the current smaller battery charge is below a corresponding smaller battery charge threshold, and / or not deactivating the discharge path of the larger battery and the discharge path of the smaller battery if the current larger battery charge is not below a corresponding larger battery charge threshold and the current smaller battery charge is not below a corresponding smaller battery charge threshold) (456). The second method 450 further includes: allowing the larger battery and / or the smaller battery to power the head-mounted wearable device 100 while enabling one or more computing tasks to be executed on the head-mounted wearable device 100 and / or another device (458). The second method 450 further includes: determining whether the discharge path of the smaller battery and / or the discharge path of the larger battery is active or inactive (460). Based on the determination that both the discharge paths of the smaller battery and the larger battery are active, the second method 450 ends (466).

[0066] Based on the determination that at least one of the discharge paths of the smaller battery and the larger battery is inactive, the second method 450 further includes: determining whether reactivation of the discharge path of the larger battery and / or the discharge path of the smaller battery is permitted based on a task checklist, a new battery temperature range, a new larger battery charge, and / or a new smaller battery charge (462). Based on the determination that reactivation of the discharge path of the larger battery and / or the discharge path of the smaller battery is permitted (e.g., the corresponding new battery charge is greater than the corresponding idle battery charge threshold), the second method 450 further includes: reactivating the corresponding discharge path (464), and the second method 450 ends (466). Based on the determination that reactivation of the discharge path of the larger battery and / or the discharge path of the smaller battery is not permitted (e.g., the corresponding new battery charge is less than the corresponding idle battery charge threshold), the corresponding discharge path remains deactivated, and the second method 450 ends (466).

[0067] Based on the determination that one or more computing tasks are not permitted (e.g., given one or more computing tasks and the current battery temperature, at least one of the smaller and larger batteries has a corresponding current battery charge less than a corresponding battery charge threshold), the second method 450 further includes: causing one or more computing tasks not to be performed at the head-mounted wearable device 100 and / or another device (468). In some embodiments, the second method 450 further includes: determining whether the discharge path of the smaller battery and / or the discharge path of the larger battery is active or inactive (460), as described above.

Alternatively or additionally, user 602 may provide user input via one or more touch surfaces of the wrist-worn wearable device 626, the AR device 628, and / or the HIPD 642; and / or voice commands acquired by the microphones of the wrist-worn wearable device 626, the AR device 628, and / or the HIPD 642. The wrist-worn wearable device 626, AR device 628, and / or HIPD 642 include an artificial intelligence digital assistant to help the user provide user input (e.g., complete a series of actions, suggest different actions or commands, provide reminders, confirm commands). For example, the digital assistant can be invoked via input occurring at AR device 628 (e.g., via input at the temple of AR device 628). In some embodiments, the user 602 can provide user input via one or more facial gestures and / or facial expressions. For example, the camera of the wrist-worn wearable device 626, AR device 628, and / or HIPD 642 can track the user 602's eyes to navigate the user interface.

[0139] The wrist-worn wearable device 626, AR device 628, and / or HIPD 642 can operate individually or in combination to allow user 602 to interact with the AR environment. In some embodiments, HIPD 642 is configured to operate as a central hub or control center for the following devices: wrist-worn wearable device 626; AR device 628; and / or another communication-coupled device. For example, user 602 can provide input at any of the wrist-worn wearable device 626, AR device 628, and / or HIPD 642 to interact with the AR environment, and HIPD 642 can identify one or more backend and frontend tasks to perform the requested interaction and issue instructions to perform the one or more backend and frontend tasks at the wrist-worn wearable device 626, AR device 628, and / or HIPD 642. In some embodiments, backend tasks are user-insensible background processing tasks (e.g., rendering content, decompression, compression, application-specific operations), while frontend tasks are user-insensible user-facing tasks (e.g., presenting information to the user or providing feedback to the user). HIPD 642 can perform backend tasks and provide operational data corresponding to the backend tasks performed to the wrist wearable device 626 and / or AR device 628, enabling the wrist wearable device 626 and / or AR device 628 to perform frontend tasks. In this way, HIPD 642 (which has more computing resources and greater thermal headroom than the wrist wearable device 626 and / or AR device 628) performs computationally intensive tasks and reduces the computing resource utilization and / or power consumption of the wrist wearable device 626 and / or AR device 628.

[0140] In the example shown in the first XR system 600a, HIPD 642 identifies one or more backend and frontend tasks associated with a user request to initiate an AR video call with one or more other users (represented by avatar 604 and contact digital representation 606); and HIPD 642 issues instructions to execute the one or more backend and frontend tasks. Specifically, HIPD 642 executes backend tasks for processing and / or rendering image data (and other data) associated with the AR video call and provides operational data associated with the executed backend tasks to AR device 628, causing AR device 628 to execute frontend tasks for presenting the AR video call (e.g., presenting avatar 604 and contact digital representation 606).

[0141] In some embodiments, HIPD 642 serves as a focal point or anchor point for information presentation. This allows user 602 to generally know where the information is presented. For example, as shown in the first XR system 600a, an avatar 604 and a digital representation 606 of a contact are presented above HIPD 642. Specifically, HIPD 642 and AR device 628 operate in combination to determine the location for presenting the avatar 604 and the digital representation 606 of the contact. In some embodiments, information can be presented within a predetermined distance from HIPD 642 (e.g., within five meters). For example, as shown in the first XR system 600a, a virtual object 608 is presented on a table at a distance from HIPD 642. Similar to the examples above, HIPD 642 and AR device 628 can operate in combination to determine the location for presenting the virtual object 608. Alternatively, in some embodiments, the presentation of information is not constrained by HIPD 642. More specifically, the avatar 604, the digital representation of the contact 606, and the virtual object 608 do not need to be presented within the predetermined distance of the HIPD 642. Although the AR device 628 is described as working with the HIPD, the MR head-mounted viewer can interact in the same way as the AR device 628.

[0142] The user input provided at the wrist wearable device 626, AR device 628, and / or HIPD 642 is coordinated to enable the user to initiate, continue, and / or complete an operation using any device. For example, user 602 can provide user input to AR device 628 to cause AR device 628 to present virtual object 608, and while AR device 628 presents virtual object 608, user 602 can provide one or more gestures via wrist wearable device 626 to interact with and / or manipulate virtual object 608. Although AR device 628 is described as working in conjunction with wrist wearable device 626, MR head-mounted viewer can interact in the same manner as AR device 628.

[0143] Integration of Artificial Intelligence and XR Systems Figure 6A An interaction is illustrated where an AI virtual assistant can assist with requests made by user 602. The AI ​​virtual assistant can be used to fulfill unlimited requests made by user 602 through natural language input. For example, in... Figure 6A In the middle, user 602 issues an audible request 644 to summarize the conversation and then share the summarized conversation with others in the meeting. Additionally, the AI ​​virtual assistant is configured to use the sensors of the XR system (e.g., the camera, microphone, and various other sensors of any device in the XR headset) to provide contextual cues to the user to initiate tasks.

[0144] Figure 6A An example neural network 652 used in artificial intelligence applications is also shown. The uses of artificial intelligence (AI) are diverse and encompass many different aspects of the devices and systems described herein. AI capabilities cover a wide range of applications and enhance the interaction between user 602 and user devices such as AR device 628, MR device 632, HIPD 642, and wrist-worn wearable device 626. The AI ​​discussed herein can be obtained using many different training techniques. While the primary AI model example discussed herein is a neural network, other AI models can also be used. Non-limiting examples of AI models include artificial neural networks (ANNs), deep neural networks (DNNs), convolutional 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 learning, among others. The AI ​​models can be implemented on one or more user devices and / or any other device among the user devices described in this paper. For devices and systems employing multiple AI models as described in this paper, different models can be used depending on the task. For example, an LLM can be used for a natural language AI virtual assistant, while a DNN can be used instead for object detection in a physical environment.

[0145] In another example, an AI virtual assistant may include many different AI models, and multiple AI models may be employed (concurrently, sequentially, or a combination of concurrent and sequential employment) based on the user's request. For example, an LLM-based AI model may provide instructions to help the user follow a recipe, and these instructions may be based in part on another AI model derived from ANNs, DNNs, RNNs, etc., capable of identifying which part of the recipe the user is performing (e.g., object and scene detection).

[0146] As AI training models evolve, the operations and experiences described herein may be performed using models different from those listed above, and those skilled in the art will understand that the list above is non-limiting.

[0147] User 602 can interact with the AI ​​model through natural language input, text input, or any other input modality that accepts natural language and / or the corresponding sound sensor module, acquired by a sound sensor. In another instance, input is provided by tracking the user 602's eye gaze via a gaze tracker module. Additionally, the AI ​​model can receive input beyond that provided by user 602. For example, the AI ​​can further generate its response based on environmental input acquired by various types of sensors and / or their corresponding sensor modules in response to a user request (e.g., temperature data, image data, video data, ambient light data, audio data, GPS location data, inertial measurement results (i.e., user motion) data, pattern recognition data, magnetometer data, depth data, pressure data, force data, neuromuscular data, heart rate data, temperature data, sleep data). Sensor data can be acquired entirely from a single device (e.g., AR device 628) or from multiple devices communicating with each other (e.g., a system including at least two of AR device 628, MR device 632, HIPD 642, wrist-worn wearable device 626, etc.). The AI ​​model can also access additional information (e.g., one or more servers 630, one or more computers 640, one or more mobile devices 650 and / or one or more other electronic devices) via network 625.

[0148] A non-limiting list of AI enhancements 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, the AI ​​enhancements are executed, wholly or partially, on a cloud computing platform coupled to a user device (e.g., AR device 628, MR device 632, HIPD 642, wrist-worn wearable device 626) via one or more network communications. The cloud computing platform provides scalable computing resources, distributed computing, managed AI services, perturbation acceleration, pre-trained models, APIs, and / or other resources to support the full computational requirements of the AI ​​enhancements.

[0149] Example outputs derived from using AI models may include natural language responses, mathematical calculations, charts displaying information, audio, images, videos, text, meeting minutes, predictions based on environmental factors, classification, pattern recognition, recommendations, evaluations, or other operations. In some embodiments, the generated outputs are stored on the local memory of a user device (e.g., AR device 628, MR device 632, HIPD 642, wrist-worn wearable device 626), storage options of external devices (servers, computers, mobile devices, etc.), and / or storage options of a cloud computing platform.

[0150] AI-based outputs can be presented across different modalities (e.g., audio-based modalities, vision-based modalities, haptic modalities, and any combination thereof) and across different devices within the XR system described herein. Some vision-based outputs may include XR enhancements on XR headsets, or information displayed on user interfaces on wrist-worn wearables, laptop devices, mobile devices, etc. Haptic feedback may provide information to user 602 on devices with or without displays (e.g., HIPD 642). The AI ​​model may also use the aforementioned inputs to determine the appropriate modality for presenting content to the user and one or more devices (e.g., audio output may be presented instead of visual output to a user walking on a busy road to avoid distracting user 602).

[0151] Example of augmented reality interaction Figure 6B A user 602 is shown wearing a wrist-worn wearable device 626 and an AR device 628, and holding a HIPD 642. In the second AR system 600b, the wrist-worn wearable device 626, the AR device 628, and / or the HIPD 642 are used to receive one or more messages and / or provide one or more messages to the user 602's contacts. Specifically, the wrist-worn wearable device 626, the AR device 628, and / or the HIPD 642 detect and coordinate one or more user inputs to initiate a messaging application and prepare a response to messages received via the messaging application.

[0152] In some embodiments, user 602 launches an application via user input on a wrist wearable device 626, AR device 628, and / or HIPD 642, the user input causing the application to launch on at least one device. For example, in a second AR system 600b, user 602 executes a gesture associated with a command (represented by the messaging user interface 612) for launching a messaging application; wrist wearable device 626 detects the gesture; and based on determining that user 602 is wearing AR device 628, causes AR device 628 to present the messaging user interface 612 of the messaging application. AR device 628 may present the messaging user interface 612 to user 602 via its display (e.g., as shown in user 602's field of view 610). In some embodiments, the application is launched and can run on a device (e.g., wrist wearable device 626, AR device 628, and / or HIPD 642) that detects user input to launch the application, and that device provides other device operation data to cause the messaging application to be presented. For example, the wrist-worn wearable device 626 can detect user input for launching a messaging application, launch and run the messaging application, and provide operational data to the AR device 628 and / or HIPD 642 to enable the presentation of the messaging application. Alternatively, the application can be launched and run on a device other than the one that detects the user input. For example, the wrist-worn wearable device 626 can detect gestures associated with launching the messaging application and enable the HIPD 642 to run the messaging application and coordinate its presentation.

[0153] Furthermore, user 602 can provide user input at the wrist wearable device 626, AR device 628, and / or HIPD 642 to continue and / or complete an operation initiated at another device. For example, after launching a messaging application via the wrist wearable device 626, and when the AR device 628 displays the messaging user interface 612, user 602 can provide input at HIPD 642 to prepare a reply (e.g., indicated by a swipe gesture performed on HIPD 642). The gesture performed by user 602 on HIPD 642 can be provided and / or displayed on another device. For example, a swipe gesture performed by user 602 on HIPD 642 is displayed on the virtual keyboard of the messaging user interface 612 displayed by AR device 628.

[0154] In some embodiments, the wrist wearable device 626, AR device 628, HIPD 642, and / or other communication-coupled devices may present one or more notifications to the user 602. The notification may be an indication of a new message, incoming call, application update, or status update, etc. The user 602 may select a notification via the wrist wearable device 626, AR device 628, or HIPD 642, causing an application or action associated with the notification to be presented on at least one device. For example, the user 602 may receive a notification of a received message at the wrist wearable device 626, AR device 628, HIPD 642, and / or other communication-coupled devices, and provide user input at the wrist wearable device 626, AR device 628, and / or HIPD 642 to view the notification. The device that detects the user input may cause the application associated with the notification to be launched and / or the application associated with the notification to be presented on the wrist wearable device 626, AR device 628, and / or HIPD 642.

[0155] While the examples above describe coordinated input for interaction with messaging applications, those skilled in the art will recognize upon reading this description that user input can be coordinated to interact with any number of applications, including but not limited to gaming applications, social media applications, camera applications, web-based applications, and financial applications. For example, AR device 628 can present game application data to user 602, while HIPD 642 can use a controller to provide input to the game. Similarly, user 602 can use wrist wearable device 626 to activate the camera of AR device 628, and the user can use wrist wearable device 626, AR device 628, and / or HIPD 642 to manipulate image capture (e.g., zoom in or out, or apply filters) and capture image data.

[0156] While AR device 628 is shown to be capable of certain functions, it should be understood that AR devices can be AR devices with different functions based on cost and market demand. For example, an AR device may include a single output modality such as an audio output modality. In another example, an AR device may include a low-fidelity display as one of the output modalities, capable of presenting simple information (e.g., text and / or low-fidelity images / videos) to the user. In yet another example, an AR device may be configured with face-facing light-emitting diodes (LEDs) configured to provide information to the user; for example, when providing direction, an LED around the right lens may illuminate to notify the wearer to turn right, or an LED on the left lens may illuminate to notify the wearer to turn left. In another embodiment, an AR device may include an outward-facing projector, enabling the display of information (e.g., text information, media) on the user's palm or other suitable surface (e.g., a table, a whiteboard). In yet another embodiment, information may also be provided by locally darkening portions of the lens to emphasize portions of the environment to which the user's attention should be directed. Some AR devices can render AR augmentations in a monocular or binocular manner (e.g., AR augmentations can be rendered on a single display associated with a single lens, rather than at two lenses to produce a binocular image). In some instances, AR devices capable of rendering AR augmentations in a binocular manner may also optionally display AR augmentations in a monocular manner (e.g., for energy-saving purposes or other presentation considerations). These examples are not exhaustive, and features of one AR device described above can be combined with features of another AR device described above. Although the features and experiences of AR devices have been described in general terms in the preceding sections, it should be understood that the described features and experiences can be applied in a similar manner to MR headsets, which will be described in the following sections.

[0157] Example of mixed reality interaction Go to Figure 6C-1 and Figure 6C-2The image shows a user 602 wearing a wrist-worn wearable device 626 and an MR device 632 (e.g., a device capable of providing a full VR or MR experience, which displays one or more objects from the physical environment on the device's display) and holding a HIPD 642. In the third AR system 600c, the wrist-worn wearable device 626, the MR device 632, and / or the HIPD 642 are used for interaction within an MR environment (e.g., a VR game or other MR / VR application). Although the MR device 632 presents a representation of the VR game to the user 602 (e.g., a first MR game environment 620), the wrist-worn wearable device 626, the MR device 632, and / or the HIPD 642 detect and coordinate one or more user inputs to allow the user 602 to interact with the VR game.

[0158] In some embodiments, user 602 may provide user input that elicits movement in the corresponding MR environment via wrist-worn wearable device 626, MR device 632, and / or HIPD 642. For example, user 602 in a third MR system 600c (such as...) Figure 6C-1 (As shown) The user 602 raises HIPD 642 in preparation for swinging it in the first MR game environment 620. MR device 632 responds to the user 602 raising HIPD 642 by causing the user's MR representation 622 to perform a similar action (e.g., raising a virtual object, such as virtual sword 624). In some embodiments, each device uses corresponding sensor data and / or image data to detect user input and provide an accurate representation of the user 602's movement. For example, the image sensor of HIPD 642 (e.g., a Simultaneous Localization and Mapping (SLAM) camera or other camera) can be used to detect the position of HIPD 642 relative to the user 602's body, allowing the virtual object to be properly positioned within the first MR game environment 620; sensor data from the wrist-worn wearable device 626 can be used to detect the speed at which the user 602 raises HIPD 642, synchronizing the user's MR representation 622 and virtual sword 624 with the user 602's movement; and the image sensor of MR device 632 can be used to represent the user 602's body, boundary conditions, or real-world objects within the first MR game environment 620.

[0159] exist Figure 6C-2In this scenario, user 602 performs a downward swing while holding HIPD 642. Wrist wearable device 626, MR device 632, and / or HIPD 642 detect the downward swing of user 602 and execute the corresponding action within the first MR gaming environment 620. In some embodiments, data captured by each device is used to enhance the user's experience within the MR environment. For example, sensor data from wrist wearable device 626 may be used to determine the speed and / or force of the downward swing, and image sensors from HIPD 642 and / or MR device 632 may be used to determine the location of the swing and how it should be represented within the first MR gaming environment 620. This can then be used as input to the MR environment (e.g., a game mechanic that can classify the user's input using aspects of the detected speed, force, location, and / or user 602's action (e.g., the user performs a tap, a hit, a critical strike, a glancing strike, a miss) or can calculate an output (e.g., damage amount)).

[0160] Figure 6C-2 It is also shown that, when displaying the MR game environment 620, a portion of the physical environment is reconstructed and displayed on the monitor of the MR device 632. In this example, when one or more objects in the physical environment are potentially in the user's path (e.g., the user is likely to collide with objects in the physical environment), a reconstruction 646 of the physical environment is displayed in place of a portion of the MR game environment 620. Thus, this example MR game environment 620 includes: (i) an immersive VR portion 648 (e.g., an environment that has no necessary counterpart in the nearby physical environment); and (ii) a reconstruction 646 of the physical environment (e.g., a table 650 and a cup 652). Although the example shown here is an MR environment that displays a reconstruction of the physical environment to avoid collisions, other uses of the reconstruction of the physical environment can be employed, such as defining the characteristics of the virtual environment based on the surrounding physical environment (e.g., virtual pillars can be placed based on objects in the surrounding physical environment, such as trees).

[0161] Although the wrist-worn wearable device 626, MR device 632, and / or HIPD 642 are described as detecting user input, in some embodiments, the user input is detected at a single device (where this single device is responsible for distributing signals to other devices for executing the user input). For example, HIPD 642 may run an application for generating a first MR game environment 620 and provide the MR device 632 with corresponding data for rendering the first MR game environment 620, as well as detect movement of the user 602 (while holding HIPD 642) to cause a corresponding action to be performed within the first MR game environment 620. 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., HIPD 642) for processing, causing the corresponding device to perform an action associated with the processed operational data.

[0162] In some embodiments, user 602 may wear a wrist-worn wearable device 626, wear an MR device 632, wear a textile-based smart garment 638 (e.g., a wearable haptic glove), and / or hold a HIPD 642 device. In this embodiment, the wrist-worn wearable device 626, the MR device 632, and / or the textile-based smart garment 638 are used in an MR environment (e.g., as referenced above). Figure 6A and Figure 6B Interaction within any AR or MR system described. Although the MR device 632 presents a representation of an MR game to the user 602 (e.g., a second MR game environment 620), the wrist wearable device 626, the MR device 632, and / or the textile-based smart clothing 638 detect and coordinate one or more user inputs to allow the user 602 to interact with the MR environment.

[0163] In some embodiments, user 602 may provide user input that elicits movement in the corresponding MR environment via wrist wearable device 626, HIPD 1542, MR device 632, and / or textile-based smart clothing 638. In some embodiments, each device uses corresponding sensor data and / or image data to detect user input and provide an accurate representation of user 602's movement. Although four different input devices are shown (e.g., wrist wearable device 626, MR device 632, HIPD 642, and textile-based smart clothing 638), each of these input devices can provide input for fully interactive with the MR environment completely independently. For example, the wrist wearable device itself can provide sufficient input for interacting with the MR environment. In some embodiments, if multiple input devices (e.g., wrist wearable device and textile-based smart clothing 638) are used, sensor fusion can be utilized to ensure that the input is correct. Although multiple input devices are described, it should be understood that other input devices can be used in combination or individually, such as, but not limited to, external motion-tracking cameras, other wearable devices mounted on different parts of the user's body, and devices that allow the user to experience walking in the MR environment while remaining substantially stationary in the physical environment.

[0164] As described above, the data captured by each device is used to enhance the user's experience within the MR environment. Although not shown, the textile-based smart clothing 638 can be used in conjunction with MR devices and / or HIPD 642.

[0165] Although some experiences are described as taking place on AR devices and others on MR devices, those skilled in the art will recognize that experiences can be transferred from MR devices to AR devices and vice versa.
