DETAILED DESCRIPTION

[0023] A wearable electronic device and a case for the wearable electronic device that can charge the wearable electronic device and additional devices are described herein. The wearable electronic device can be charged wirelessly by the case, and exposed connectors can be limited or absent from the wearable electronic device, reducing weight, improving portability, and limiting damage potential given the lack of cabling between the wearable electronic device and the case. The case can be configured to provide updates to the wearable electronic device and provide power according to a priority algorithm to charge both the wearable electronic device and other devices according to needs of the user. The case for the wearable electronic device can function as a portable power pack and replace the need for separate batteries or cables, reducing the number of components to be carried or accessed by the user of the wearable electronic device.

[0024] The wearable electronic device includes a lens, an inductive coil positioned around the lens, a storage device, and a transceiver. The inductive coil wirelessly charges the wearable electronic device and provides a data interface to send and receive wireless data signals. The storage device stores settings of the wearable electronic device and software that controls the wearable electronic device. The transceiver transmits an identifier of the wearable electronic device and receives a software update for the wearable electronic device, the software update based on the identifier of the wearable electronic device.

[0025] The case for the wearable electronic device includes an interior portion to accommodate the wearable electronic device therein, a lid attached to the case, a first set of inductive coils positioned in the interior portion of the case, and a second set of inductive coils disposed on an outer surface of the lid. The first set of inductive coils wirelessly charges the wearable electronic device and provides a data interface between the wearable electronic device and the case when the wearable electronic device is positioned in the interior portion of the case. When the lid is in a closed position, additional devices may be wirelessly charged by the second set of inductive coils when the additional devices are placed on a corresponding one of the second set of inductive coils.

[0026] The case may also include a sensor located on an exterior of the case and a storage device. The sensor captures map information of a physical environment where the case is located. The storage device stores the map information captured by the sensor. Alternatively, the sensor features of the case may be included in an embodiment of the case that does not include the second set of inductive coils.

[0027] A method for wirelessly charging multiple devices positioned on a charging device is also described herein. The charging device receives charging parameters from each device positioned on the charging device. The charging parameters include a current charge level, a target charge level, and a maximum charge level. The charging device selects a device positioned on the charging device with a highest charging priority. The charging device charges the selected device at a high power level until the selected device has reached its target charge level. The charging device charges devices other than the selected device that are positioned on the charging device at a low power level. The charging device charges the selected device at the low power level after the selected device has reached its target charge level and until the selected device has reached its maximum charge level.

[0028] FIG. 1 is a diagram of a wearable electronic device 100 in the form of glasses. As an example, the wearable electronic device 100 may be a device that is configured to display computer-generated content to a user in conjunction with a view of a physical environment around the user. The wearable electronic device 100 includes a first lens 102 and a second lens 104 connected by a nosepiece 106. A first arm 108 extends away from the first lens 102. A second arm 110 extends away from the second lens 104. The first lens 102 includes a first inductive coil 112. The second lens 104 includes a second inductive coil 114. In some examples, a single inductive coil (not shown) is present and surrounds either the first lens 102 or the second lens 104.

[0029] The first inductive coil 112 and/or the second inductive coil 114 are used in connection with corresponding inductive coil(s) of a separate device (some examples of a separate device are described below) to provide wireless power and a wireless data link (by sending and receiving wireless data signals) in accordance with inductive charging principles. In some implementations, the wireless data link may be established according to a data communications protocol such as Universal Serial Bus (USB) or near-field communications (NFC). In some implementations, the first inductive coil 112 and the second inductive coil 114 may function as an antenna.

[0030] In some implementations, the first inductive coil 112 and the second inductive coil 114 are made of one or more wire loops. In some implementations, the first inductive coil 112 surrounds a see-through portion of the first lens 102 and the second inductive coil 114 surrounds a see-through portion of the second lens 104. In some implementations, the first inductive coil 112 and the second inductive coil 114 may take different shapes, provided that the positioning of the first inductive coil 112 and the second inductive coil 114 does not interfere with the user wearing the wearable electronic device 100 from seeing through the first lens 102 and the second lens 104.

[0031] In some implementations, the wearable electronic device 100 includes electronic components 116, 118 (shown by dashed lines in FIG. 1). The electronic components 116, 118 may include a battery, a processor, a storage device, a transceiver, and control electronics. The electronic components 116, 118 are not individually shown for simplicity. The electronic components 116, 118 may be positioned in the first arm 108, in the second arm 110, or in both the first arm 108 and the second arm 110 as shown. The electronic components 116, 118 are connected to the first inductive coil 112 and the second inductive coil 114 via wiring extending through the first arm 108 and/or the second arm 110. In some implementations, the electronic components 116, 118 may be connected to the first inductive coil 112 and the second inductive coil 114 by an electromagnetic connection or by an electrical connection. [0032] The battery may be charged by power received via the first inductive coil 112 and/or the second inductive coil 114. The battery may provide power to the processor, the storage device, the transceiver, and the control electronics. The transceiver may send and receive data via the first inductive coil 112 and/or the second inductive coil 114. In some implementations, the processor may cause data to be sent and received via the first inductive coil 112 and/or the second inductive coil 114. In some implementations, the wearable electronic device 100 may include a frame (not shown) that surrounds the first lens 102 and the second lens 104, and the first inductive coil 112 and the second inductive coil 114 may be embedded in the frame.

[0033] In some implementations, the wearable electronic device 100 includes display components 120, 122 which may be powered by the battery. As shown in FIG. 1, the display component 120 is located on an upper portion of the first lens 102 and the display component 122 is located on an upper portion of the second lens 104. In some implementations, the display components 120, 122 may be located in other positions provided that the display components 120, 122 are located adjacent to the first lens 102 and the second lens 104. In some implementations, the display components 120, 122 are light emitting display components coupled with an optical combiner (not shown) included in the first lens 102 and the second lens 104 to overlay content (via emitted light) onto a physical environment scene that the user sees through the first lens 102 and the second lens 104. In some implementations, only one of the display components 120, 122 is present. In some implementations, the display components 120, 122 may have a different shape than that shown in FIG. 1, but the shape of the display components 120, 122 does not affect the operation of the display components 120, 122.

[0034] FIG. 2 is a diagram of a wearable electronic device 200 in the form of goggles, for example, sports goggles or a diving mask. The wearable electronic device 200 may be a device that is configured to display computer-generated content to a user in conjunction with a view of a physical environment around the user. The wearable electronic device 200 includes a lens 202. In some implementations, the lens 202 is shaped to accommodate the user’s nose in the middle of the lower portion of the lens 202. A first arm 208 extends away from one side of the wearable electronic device 200 and a second arm 210 extends away from an opposite side of the wearable electronic device 200.

[0035] A first inductive coil 212 is positioned on one end of the lens 202 and a second inductive coil 214 is positioned on an opposite end of the lens 202. The first inductive coil 212 and the second inductive coil 214 are used in connection with corresponding inductive coils of a separate device (some examples of a separate device are described below) to provide wireless power and a wireless data link (by sending and receiving wireless data signals) in accordance with inductive charging principles. In some implementations, the wireless data link may be established according to a data communications protocol such as Universal Serial Bus (USB) or near-field communications (NFC). In some implementations, the first inductive coil 212 and the second inductive coil 214 may function as an antenna. [0036] The first inductive coil 212 and the second inductive coil 214 are positioned such that when the user is wearing the wearable electronic device 200, the user can see through the lens 202 without having their vision obstructed by the first inductive coil 212 or the second inductive coil 214. In some implementations, the first inductive coil 212 and the second inductive coil 214 are made of one or more wire loops. In some implementations, the first inductive coil 212 and the second inductive coil 214 may take different shapes, provided that the positioning of the first inductive coil 212 and the second inductive coil 214 does not interfere with the user from seeing through the lens 202. In some implementations, there may be only one inductive coil (not shown) in the wearable electronic device 200.

[0037] In some implementations, the wearable electronic device 200 includes electronic components 216, 218 (shown by dashed lines in FIG. 2). The electronic components 216, 218 may include a battery, a processor, a storage device, a transceiver, and control electronics.

The electronic components 216, 218 are not individually shown for simplicity. The electronic components 216, 218 may be positioned in the first arm 208, in the second arm 210, or in both the first arm 208 and the second arm 210. The electronic components 216, 218 are connected to the first inductive coil 212 and the second inductive coil 214 via wiring extending through the first arm 208 and/or the second arm 210. In some implementations, the electronic components 216, 218 may be connected to the first inductive coil 212 and the second inductive coil 214 by an electromagnetic connection or by an electrical connection. [0038] The battery may be charged by power received via the first inductive coil 212 and/or the second inductive coil 214. The battery may provide power to the processor, the storage device, the transceiver, and the control electronics. The transceiver may send and receive data via the first inductive coil 212 and/or the second inductive coil 214. In some implementations, the processor may cause data to be sent and received via the first inductive coil 212 and/or the second inductive coil 214. In some implementations, the wearable electronic device 200 may include a frame that surrounds the lens 202, and the first inductive coil 212 and/or the second inductive coil 214 may be embedded in the frame.

[0039] In some implementations, the wearable electronic device 200 includes display components 220, 222 which may be powered by the battery. As shown in FIG. 2, the display component 220 is located on an upper left portion of the lens 202 and the display component 222 is located on an upper right portion of the lens 202. In some implementations, the display components 220, 222 may be located in other positions provided that the display components 220, 222 are located adjacent to the lens 202. In some implementations, the display components 220, 222 are light emitting display components coupled with an optical combiner (not shown in FIG. 2) included in the lens 202 to overlay content (via emitted light) onto a physical environment scene that the user sees through the lens 202. In some implementations, only one of the display components 220, 222 is present. In some implementations, the display components 120, 122 may have a different shape than that shown in FIG. 1, but the shape of the display components 120, 122 does not affect the operation of the display components 120, 122.

[0040] In some implementations, the wearable electronic devices 100, 200 include associated control software. The control software may be stored in the storage device and executed by the processor or the control electronics. The transceiver in the wearable electronic devices 100, 200 transmits an identifier associated with the wearable electronic devices 100, 200 via the inductive coils to receive a software update that is specific to the wearable electronic devices 100, 200. The wearable electronic devices 100, 200 then receive the software update via the inductive coils and the transceiver. In some implementations, the processor in the wearable electronic devices 100, 200 causes the inductive coils to transmit an identifier associated with the wearable electronic devices 100, 200 to receive a software update that is specific to the wearable electronic devices 100, 200. The wearable electronic devices 100, 200 then receive the software update via the inductive coils.

[0041] In some implementations, different configurations of the wearable electronic devices 100, 200 have different identifiers so that a software update received by the wearable electronic devices 100, 200 is specific to that configuration of the wearable electronic devices 100, 200. Different software updates can thus be received by the wearable electronic devices 100, 200 based on the different identifiers. For example, the wearable electronic device 100 may include a feature to automatically tint the lenses 102, 104 based on an amount of ambient light. If the wearable electronic device 200 does not include this feature, the wearable electronic device 200 does not need to receive a software update relating to this feature.

[0042] By customizing the software update based on the configuration of the wearable electronic devices 100, 200, a user of the wearable electronic devices 100, 200 may receive a smaller software update which may be received by the wearable electronic devices 100, 200 faster than a more general software update that includes updates for all possible features and configurations of the wearable electronic devices 100, 200 even if the user’s wearable electronic devices 100, 200 do not include such features. Providing a smaller software update is beneficial to a user of the wearable electronic devices 100, 200 if the wearable electronic devices 100, 200 include a low-speed data interface because the update will be received faster by the wearable electronic devices 100, 200. In some implementations, settings of the wearable electronic device 100, 200 may be updated in a similar manner as a software update, utilizing the respective identifiers of the wearable electronic devices 100, 200 to ensure that the settings specific to the wearable electronic devices 100, 200 are updated.

[0043] It is noted that in some implementations, using the identifier in conjunction with the wearable electronic device to receive a device-specific software update may be used in other wearable electronic devices other than the wearable electronic devices 100, 200. For example, using the identifier to receive a device-specific software update may be used with any type of wearable electronic device that is capable of presenting a computer-generated environment to a user of the wearable electronic device, such as a device including a housing with content display components and inductive coils (e.g., a virtual reality (VR) headset). [0044] FIG. 3 is a top view of a charging device 324 that is charging two electronic devices 300. The charging device 324 is a powered device capable of providing wireless power and/or wireless data to a corresponding device that is configured to receive wireless power and/or wireless data (i.e., the electronic devices 300). As an example, the charging device 324 may be a charging mat or a laptop computer. The charging device 324 has an outer surface 326 with multiple inductive coils 328. In some implementations, the inductive coils 328 may be made of one or more wire loops. The inductive coils 328 are positioned relative to the outer surface 326 so that the inductive coils 328 can establish an inductive charging and/or data communication connection with the electronic devices 300 when the inductive coils of electronic devices 300 are placed on corresponding inductive coils 328 on the outer surface 326.

[0045] As an example, the inductive coils 328 may be located under a material (e.g., glass, plastic, synthetic rubber, textile, aluminum, etc.) that makes up the outer surface 326. As an example, the inductive coils 328 may be embedded in a material that defines the outer surface 326. The number of inductive coils 328 included in the charging device 324 may vary and may correspond in size and shape to the inductive coils in the electronic devices 300. In some implementations, the outer surface 326 may include visual indicators to identify where the inductive coils 328 are located and to enable proper placement of the electronic devices 300 on the inductive coils 328. The electronic devices 300 may include the wearable electronic devices 100, 200, the cases 530, 630, 730, 930, 1030, or other wirelessly chargeable devices such as the wirelessly chargeable devices 748, 750 described herein. The two electronic devices 300 shown in FIG. 3 are exemplary and the number of electronic devices 300 that may be charged by the charging device 324 corresponds to the number of inductive coils 328 included in the charging device 324.

[0046] FIG. 4 is a top view of a charging device 424 that is charging a single electronic device 400. The electronic device 400 may include the wearable electronic devices 100, 200, the cases 530, 630, 730, 930, 1030, or other wirelessly chargeable devices such as the wirelessly chargeable devices 748, 750 described herein. The charging device 424 is a powered device capable of providing wireless power and/or wireless data to a corresponding device that is configured to receive wireless power and/or wireless data (i.e., the electronic device 400). As an example, the charging device 424 may be a charging mat or a cellular telephone. The charging device 424 has an outer surface 426 with one inductive coil 428. In some implementations, the inductive coil 428 may be made of one or more wire loops. The inductive coil 428 is positioned relative to the outer surface 426 so that the inductive coil 428 can establish an inductive charging and/or data communication connection with the electronic device 400 when an inductive coil of the electronic device 400 is placed on the inductive coil 428 on the outer surface 426.

[0047] As an example, the inductive coil 428 may be located under a material (e.g., glass, plastic, synthetic rubber, textile, aluminum, etc.) that makes up the outer surface 426. As another example, the inductive coil 428 may be embedded in a material that defines the outer surface 426. The inductive coil 428 is sized and shaped such that when the electronic device 400 is placed on the inductive coil 428, the inductive coil(s) of the electronic device 400 at least partially overlaps the inductive coil 428. In some implementations, the outer surface 426 may include a visual indicator (not shown) to identify where the inductive coil 428 is located to enable proper placement of the electronic device 400 on the inductive coil 428.

[0048] FIG. 5 is a diagram of a case 530 for charging a wearable electronic device with a lid 532 in an open position. The case 530 is positioned in contact with a charging device 524. The wearable electronic device is not shown in FIG. 5 to avoid obscuring the features described herein, though can be similar to the wearable electronic device 100 or the wearable electronic device 200. An interior portion 534 of the case 530 includes a first inductive coil 536 and a second inductive coil 538. In some implementations, the first inductive coil 536 and the second inductive coil 538 may be made of one or more wire loops. The interior portion 534 of the case 530 is sized and shaped to accommodate the wearable electronic device therein when the lid 532 is in a closed position.

[0049] The charging device 524 is a powered device capable of providing wireless power and/or wireless data to the case 530 while the case 530 rests on the charging device 524. That is, the case 530 (as well as other electronic devices, not shown) may be configured to receive wireless power and/or wireless data from the charging device 524 upon contact between the case 530 and the charging device 524. As an example, the charging device 524 may be a charging mat, a laptop computer, or another electronic device (not shown).

[0050] The first inductive coil 536 and the second inductive coil 538 within the case 530 are sized and shaped to correspond with the inductive coils in the wearable electronic device. When the wearable electronic device is placed in the interior portion 534 and the inductive coils of the wearable electronic device are placed on the first inductive coil 536 and the second inductive coil 538, the wearable electronic device may be wirelessly charged by the case 530 and/or receive data from the case 530. In some implementations, the interior portion 534 may include a visual indicator (not shown) to identify where the first inductive coil 536 and the second inductive coil 538 are located to enable proper placement of the wearable electronic device.

[0051] In some implementations, the interior portion 534 may be configured (for example, by including contours to the interior portion 534) so that when the wearable electronic device is positioned in the interior portion 534, the inductive coils of the wearable electronic device are precisely aligned with the first inductive coil 536 and the second inductive coil 538. By having a precise alignment between the inductive coils of the wearable electronic device and the first inductive coil 536 and the second inductive coil 538, the wireless charging and/or the wireless data transfer will be more efficient (e.g., a faster power transfer and/or a faster data transfer).

[0052] FIG. 6 is a partial see-through diagram of a case 630 for charging a wearable electronic device 600 with a lid 632 in a closed position. The wearable electronic device 600 may be similar to the wearable electronic device 100 or the wearable electronic device 200. The lid 632 has an outer surface 626 with a first inductive coil 640 and a second inductive coil 642. In some implementations, the first inductive coil 640 and the second inductive coil 642 may be made of one or more wire loops. The first inductive coil 640 and the second inductive coil 642 are positioned relative to the outer surface 626 so that the first inductive coil 640 and the second inductive coil 642 can establish an inductive charging and/or data communication connection with an electronic device (not shown in FIG. 6) when an inductive coil of the electronic device is placed on the corresponding first inductive coil 640 and/or the second inductive coil 642 on the outer surface 626.

[0053] As an example, the first inductive coil 640 and the second inductive coil 642 may be located under a material (e.g., glass, plastic, synthetic rubber, textile, aluminum, etc.) that makes up the outer surface 626. As an example, the first inductive coil 640 and the second inductive coil 642 may be embedded in a material that defines the outer surface 626. In some implementations, the outer surface 626 may include visual indicators to identify where the first inductive coil 640 and the second inductive coil 642 are located, to enable proper placement of the electronic device(s) on the first inductive coil 640 and the second inductive coil 642. In some implementations, the outer surface 626 may include one inductive coil or more than two inductive coils.

[0054] A battery 644 is located at a bottom of an interior portion of the case 630 (shown in FIG. 6 by a dashed outline). The wearable electronic device 600 is shown in FIG. 6 in the interior portion of the case 630 (shown by a dash-dot outline) and is positioned on inductive coils located in the interior portion of the case 630 and above the battery 644 (the inductive coils are not shown in FIG. 6). A power cable connector 646 is located on an exterior of the case 630 and is sized and shaped to receive a power cable. Additional electronics in the case 630 (not shown in FIG. 6) provide power from the power cable connector 646 to the battery 644, to the inductive coils in the interior portion of the case 630, and to the first inductive coil 640 and the second inductive coil 642. The case 630 may simultaneously provide wireless power to the wearable electronic device 600 and any devices (not shown, such as mobile devices, music players, wireless speakers, etc.) placed on the first inductive coil 640 and/or the second inductive coil 642. The case 630 may also be configured for wireless charging, for example, using a charging device (not shown) similar to the charging devices 324, 424, 524. [0055] FIG. 7 is a diagram of a case 730 for charging a wearable electronic device (not shown) with a lid 732 in a closed position and two wirelessly chargeable devices 748, 750 being charged on an outer surface 726 of the lid 732. The case 730 may be constructed in a similar manner as the case 630 and may include a battery therein (not shown). A power cable connector 746 is located on an exterior of the case 730 and is sized and shaped to receive a power cable (not shown). The case 730 may also be configured for wireless charging, for example, using a charging device (not shown) similar to the charging devices 324, 424, 524. [0056] The outer surface 726 includes a first inductive coil 740 and a second inductive coil 742. In some implementations, the first inductive coil 740 and the second inductive coil 742 may be made of one or more wire loops. The first inductive coil 740 and the second inductive coil 742 are positioned relative to the outer surface 726 so that the first inductive coil 740 and the second inductive coil 742 can establish an inductive charging and/or data communication connection with the wirelessly chargeable devices 748, 750 when respective inductive coils (not shown) of the wirelessly chargeable devices 748, 750 are placed on the corresponding first inductive coil 740 and/or the second inductive coil 742 on the outer surface 726. The wirelessly chargeable devices 748, 750 may include mobile devices, music players, wireless speakers, etc.

[0057] As an example, the first inductive coil 740 and the second inductive coil 742 may be located under a material (e.g., glass, plastic, synthetic rubber, textile, aluminum, etc.) that makes up the outer surface 726. As an example, the first inductive coil 740 and the second inductive coil 742 may be embedded in a material that defines the outer surface 726. In some implementations, the outer surface 726 may include visual indicators (not shown) to identify where the first inductive coil 740 and the second inductive coil 742 are located to enable proper placement of the wirelessly chargeable devices 748, 750 on the first inductive coil 740 and the second inductive coil 742. The number of wirelessly chargeable devices that may be charged or may receive data by placing the devices on the outer surface 726 corresponds to a number of inductive coils on the outer surface 726. For purposes of illustration, only two wirelessly chargeable devices 748, 750 are shown in FIG. 7.

[0058] FIG. 8 is a flowchart of a method 852 for charging multiple devices positioned on a charging device. The method 852 may be implemented in connection with a charging device capable of charging multiple devices, such as the charging devices 324, 524, the case 630, or the case 730. The devices to be charged by the charging device may include the wearable electronic devices 100, 200, 600, the electronic device 300, the cases 530, 630, 730 (for example, when charged using the charging devices 324, 524), or the wirelessly chargeable devices 748, 750.

[0059] As devices are positioned on the charging device, the charging device receives charging parameters from each device (operation 854). The charging device may receive the charging parameters via inductive coils or other wireless protocols (e.g., WiFi or Bluetooth®) if the charging device includes the corresponding equipment. The charging parameters for each device include a current charge level of the device, a target charge level for the device, and a maximum charge level of the device. In some implementations, the charging parameters may also include an identifier of the device.

[0060] The charging device selects a device with a highest charging priority (operation 856). In some implementations, the highest charging priority is assigned to the device with a lowest current charge level. In some implementations, the highest charging priority is assigned based on the identifier of the device. In some implementations, the highest charging priority is assigned to the wearable electronic device 100, the wearable electronic device 200, the electronic device 300, or the wearable electronic device 600, if present. In some implementations, the highest charging priority is assigned to the case 530, the case 630, or the case 730, if present.

[0061] The selected device with the highest charging priority is charged at a high power level (operation 858). The other devices positioned on the charging device are charged at a low power level (operation 860). The high power level provides more power than the low power level so that the device being charged at the high power level charges faster than devices being charged at the low power level. When the charging device is charging multiple devices, it may not be possible for the charging device to provide a same power level to all of the devices for charging, for example, due to a total maximum power draw of the charging device or due to heat dissipation constraints of the charging device. By differentiating between the devices based on the charging priority of the devices, the high power level, and the low power level, the charging device is able to provide at least some power to all of the devices positioned on the charging device.

[0062] If the selected device has not reached its target charge level (operation 862), then the selected device remains charging at the high power level (operation 858) and the other devices remain charging at the low power level (operation 860). Once the selected device has reached its target charge level (operation 862), then the selected device is charged at the low power level (operation 864) and the device with a next highest priority level is selected (operation 866). The device with the next highest priority level is then charged at the high power level (operation 858) and the method 852 continues, selecting each device positioned on the charging device for the high power level, until all devices positioned on the charging device have been charged to their maximum charge levels.

[0063] In some implementations, the charging device may support additional communication protocols (e.g., WiFi or Bluetooth®) to enable the charging device to receive the charging parameters from devices that do not support wireless data transfer via the inductive coils. In some implementations, the target charge level is 80% of the maximum charge level. In some implementations, the charging device includes a user interface so that a user may be alerted when a device has reached its target charge level and/or its maximum charge level.

[0064] FIG. 9 is a diagram of a case 930 for charging an electronic device (e.g., the wearable electronic device 100, the wearable electronic device 200, the electronic device 300, or the electronic device 400). A lid 932 of the case 930 is shown in a closed position. A power cable connector 946 is located on an exterior of the case 930 and is sized and shaped to receive a power cable (not shown). The case 930 may receive power wirelessly, for example, using a charging device (not shown) such as the charging devices 324, 424, 524. One or more sensors 968, 970, 972 are positioned in different places on the exterior of the case 930. The number of sensors shown in FIG. 9 is exemplary, and any number of sensors, in any size and shape, may be located on the exterior of the case 930.

[0065] The sensors 968, 970, 972 are used to capture features of a physical environment where the case 930 is located. For example, if the case 930 is located in a room of a home, the sensors 968, 970, 972 may capture the location of furniture in the room to “map” the room for a computer-generated environment by capturing map information for use by the wearable electronic device that receives updates from the case 930. The map information may be in any format usable by the wearable electronic device in connection with rendering the computer-generated environment. The sensors 968, 970, 972 may be audio or video sensors, for example, or may include a visible spectrum camera, an infrared camera, a depth camera, or a LiDAR sensor.

[0066] In some implementations, when the case 930 has completed mapping the room, the case 930 wirelessly transmits the map information to the wearable electronic device. By using the sensors 968, 970, 972 on the case 930 to map the room, a user of the wearable electronic device may be placed into a computer-generated environment as soon as the wearable electronic device is worn and the user does not need to wait for the wearable electronic device to separately map the room using sensors that are located on the wearable electronic device. In some implementations, the case 930 includes a storage device (not shown) that stores the map information for later transmission to the wearable electronic device (for example, a next time the wearable electronic device is placed in the case 930 or is located near the case 930). In some implementations, if the physical environment has changed, the sensors 968, 970, 972 may detect the changes, update the map information with the changes, and store the updated map information. In some implementations, the updated map information is stored separately as a smaller update to enable a faster update for the wearable electronic device.

[0067] FIG. 10 is a diagram of a case 1030 for charging an electronic device (e.g., the wearable electronic device 100, the wearable electronic device 200, the electronic device 300, or the electronic device 400). A lid 1032 of the case 1030 is shown in a closed position. A power cable connector 1046 is located on the exterior of the case 1030 and is sized and shaped to receive a power cable (not shown). The case 1030 may receive power wirelessly, for example, using a charging device (not shown) such as the charging devices 324, 424, 524. [0068] Several user interface elements are located on an exterior of the case 1030. For example, a display 1074, a first control component 1076, a second control component 1078, a microphone 1080, and a speaker 1082 may be located on the exterior of the case 1030. The display 1074 may include a touchscreen display. The first control component 1076 and the second control component 1078 may be, for example, a touch control, a button, a switch, an indicator light, or a haptic feedback element. The microphone 1080 and the speaker 1082 may be used to interact with a voice controlled system. The user interface elements 1074- 1082 shown in FIG. 10 are exemplary in size, shape, and function, and additional or different user interface elements may be located on the exterior of the case 1030. The user interface elements 1074-1082 permit a user to receive information relating to the case 1030, the wearable electronic device (e.g., as stored within the case 1030), or general information, and to interact with features of the case 1030 or the wearable electronic device.

[0069] Methods and systems described herein may be used to experience simulated environments, described, for example, using the term computer-generated reality (CGR). CGR refers to content that can be experienced with a device that allows a user to interact with the simulated environment. Simulation of the environment may be achieved by display of content using a device in conjunction with movement tracking of a user or the device as interaction occurs. For example, user gestures, user gaze, and device position may all indicate a user’s interaction with the simulated environment.

[0070] The term CGR is intended to cover the term virtual reality (VR) where a user is isolated from a surrounding physical environment while electronic content is presented for interaction to user, such as through a head-mounted device. That is, VR may provide inputs, such as haptic, audible, visual, or other inputs while the user experiences the simulated environment. The term CGR is also intended to cover the term mixed reality (MR) where a user both experiences the surrounding physical environment and receives electronic content for interaction. For example, visual and audible inputs can be layered over a view of the surrounding physical environment. A variety of devices, including the devices and systems described herein, can be used to implement and experience CGR.

[0071] Methods and systems described herein may include collecting and storing data that includes personal information that can be used to identify, locate, or contact a specific user. Use of personal information can improve a user’s experience. Collection of such personal information will be for valid uses and will be performed with user consent. Handling of such personal information will comply with security protocols, laws of various jurisdictions, and established privacy practices. Personal information may be used to improve a user’s experience at the discretion of the user, but the methods and systems will function as described in the absence of personal information.
