[0001] The described embodiments generally relate to electronic devices with removable components. More specifically, the present embodiments relate to head-mountable devices with deployable processing cartridges. Background Art

[0002] Head-mounted displays (HMDs) are developed to be comfortably worn for extended periods of time. The increasing desire to improve the performance, functionality, and battery life of HMDs has resulted in devices including several electronic components, each of which adds weight to the system. There is a constant balance between maximizing user comfort while maintaining or enhancing the performance and functionality of the device. Unbalanced weight distribution felt by a user when wearing a head-mounted display, especially weight distribution in front of the user's face, can negatively impact the user's experience. Therefore, there is a need for a lightweight HMD assembly that does not sacrifice performance or functionality.

[0003] Furthermore, the desire to improve functionality and performance while reducing the form factor of the device has created challenges in properly cooling or ventilating the device.Therefore, there is a need to more effectively dissipate heat from the HMD. Summary of the invention

[0028] Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover substitutions, modifications and equivalents that may be included within the spirit and scope of the described embodiments defined by the appended claims.

[0029] The desire to improve the performance, functionality, and battery life of HMDs has resulted in devices that may include several heavy electronic components, which may affect the ability to maintain user comfort. Ensuring user comfort is a challenge for conventional HMDs. Therefore, there is a need for a lightweight HMD assembly that does not sacrifice performance or functionality.

[0030] The present systems and methods provide an HMD with a removable or deployable case. The case may include one or more electronic components of the HMD. For example, the case may include at least one of a processor, a battery, a memory, a sensor, or a fan of the HMD. In some examples, the case may be referred to as a processing case, a puck, an accessory, an electronic accessory, or a processor. As used herein, a "case" may refer to any container, housing, or enclosure that carries components and is ready to be inserted into or attached to the HMD.

[0031] In some examples, the box may include a housing to house the various components of the box. The housing may be made of metal, plastic, or any other suitable material to protect and house the electronic components. The processor may be housed in an internal volume defined by the housing. As used herein, a "processor" may refer to any number of computing components capable of executing or implementing instructions of a computer program. For example, a "processor" may refer to a single-core or multi-core processor, a dedicated processor, or any other controller capable of executing instructions. In some examples, a "processor" may refer to a central processing unit or a main processor or primary processor used by an electronic device. In some examples, the processor may provide video output to the HMD. Therefore, although it may be separated from the HMD, the box may house the main processor of the HMD, and in some examples, it is the only processor.

[0032] In some examples, the box may weigh approximately 100 to 150 grams. The box may account for approximately 25% to 30% of the weight of the assembly. Therefore, removing the box from the HMD can greatly improve the wearer's comfort, even when worn for long periods of time.

[0033] The box may be housed, attached, mounted, or otherwise carried by the HMD. As used herein, an "HMD assembly," "assembly," or system may refer to the HMD (i.e., display unit) and the box, regardless of whether the box is attached to or deployed from the HMD. The HMD assembly may include an attachment interface to removably connect the box and the HMD. The attachment interface may include features present on both the box and the HMD. In some examples, the attachment interface is only on the box or the HMD and engages with a portion of the other for attachment.

[0034] The attachment interface may include any suitable connector, fastener, strap, band, magnet, Velcro, buckle, friction fit, or any other suitable system for removably attaching the case to or in the HMD. In some examples, the attachment interface is disposed in a slot defined by the HMD and is sized / shaped to accommodate the case. In some examples, the slot itself serves as the attachment interface.

[0035] The HMD may include a housing that at least partially forms a slot, hole, cavity, or recess to accommodate the box. As used herein, "slot" may refer to any hole, gap, cavity, recess, or depression, and is not limited to any particular geometry. The box may be located in the slot and may be removed according to the user's expectations. Therefore, the HMD assembly may include a variety of configurations or modes. In a first mode, the box may be positioned in the slot. When the box is positioned in the slot, the box may provide image data to the HMD via a cable connection or a direct electrical connection. In a second configuration, the box may be removed from the slot. When removed from the slot, the box may still provide image data to the HMD via a wired or wireless connection. When removed, the box may be positioned in many different convenient locations. For example, the box may be held by the user, placed in a pocket, placed on a table or desk, attached to an HMD holding band, etc.

[0036] Furthermore, the desire to improve functionality and performance while reducing the form factor of the device brings with it the challenge of adequately cooling or ventilating the device to prevent overheating. Thus, there is a need to more effectively dissipate heat from the HMD. The deployable case can advantageously reduce heat within the system by including one or more onboard fans to cool the interior volume of the case and / or the interior volume of the HMD. Furthermore, when the case is removed from the HMD, the interior of the HMD can dissipate heat more effectively through the volume of the cavity left after the case is removed.

[0037] In some examples, the box may include one or more input elements for a user to provide input to the HMD. In other words, the box may include a remote control or other input functionality for the HMD. Thus, the box may include a CPU for a controller, a power source for the HMD, and also input elements for the HMD, all without being integrally or structurally attached to the HMD.

[0038] The box may include various sensors to detect the box's environment. The sensors on the box may include visual sensors, thermal sensors, motion sensors, light sensors, force sensors, humidity sensors, audio sensors, capacitive sensors, etc.

[0039] The HMD assembly may include one or more boxes. In some examples, the assembly includes a primary box (e.g., a mother device) and a secondary box or a matching box (e.g., a child device). The primary box and the secondary box may communicate via Bluetooth or any other wireless or wired communication protocol. In some examples, both the primary box and the secondary box may be attached to or inserted into the HMD. In some examples, the primary box and the secondary box may be attached to each other before integration with the HMD. In some examples, the primary box and the secondary box may be independently integrated with the HMD (i.e., separated from each other).

[0040] In some examples, the box may include a projector to project a virtual keyboard onto a surface in front of the user. The user may then interact with the virtual keyboard to provide input to the HMD. The box may also include sensors to detect and determine input received via the virtual keyboard.

[0041] In some examples, the box may include a triangulation IMU system that can use sensor fusion with visual input to detect input on a virtual keyboard. Visual sensors from the HMD may be combined with sensors from the box to generate a virtual keyboard.

[0042] Refer to Figures 1 to Fig.13To discuss these embodiments and other embodiments. However, those skilled in the art will readily appreciate that the detailed description of these figures given herein is for illustrative purposes only and should not be construed as being restrictive. In addition, as used herein, a system, method, product, component, feature, or sub-feature comprising at least one of a first option, a second option, or a third option should be understood to refer to a system, method, product, component, feature, or sub-feature comprising one of each listed option (e.g., only one first option, only one second option, only one third option), a single listed option of multiple (e.g., two or more first options), two options at the same time (e.g., one first option and one second option), or a combination thereof (e.g., two first options and one second option).

[0043] Figure 1A A top view of a head-mountable assembly 100 is shown. Assembly 100 may include an HMD 102 (also referred to herein as a "display" or "display unit"), a retaining strap 110, and a box 104 electrically connected to HMD 102 via a wire or cable 106.

[0044] HMD 102 may include a display ( Figure 1A 102 and a frame or housing 103 of the HMD 102 attached to the display. In some examples, the display includes an opaque, less transparent, transparent, or translucent screen, including any number of lenses, for presenting image data. The housing 103 may at least partially abut one or more edges of the display. In some examples, the housing 103 may be configured to contact the user's face or head 111. In some examples, the housing 103 blocks external light and limits the user's peripheral vision. Various components of the HMD 102 may be positioned and fixed within the housing 103. For example, hardware and electronic devices that allow the functionality of the HMD 102 may be housed within the housing 103.

[0045] Assembly 100 may be worn on a user's head 111 such that HMD 102 is positioned above the user's face and disposed above one or both of the user's eyes. HMD 102 may be connected to a retaining strap 110. In some examples, retaining strap 110 may be positioned against and in contact with the sides and back of the user's head 111. In some examples, retaining strap 110 may be positioned at least partially above one or both of the user's ears. In some examples, retaining strap 110 may be positioned adjacent to one or both of the user's ears. Retaining strap 110 may extend around the user's head 111. In this manner, HMD 102 and retaining strap 110 may form a loop that may retain assembly 100 on the user's head 111. However, it should be understood that Figure 1AThe configuration shown is only one example of how the components of a modular wearable device may be arranged, and in some examples, a different number of connector strips and / or retention strips may be included.

[0046] In some examples, the box 104 may include the main controller or processor on which the HMD 102 operates. In some examples, the box 104 may include the only processor of the HMD assembly 100. In some examples, the box 104 may include a main logic board (MLB) of the HMD 102. The box 104 may include a battery that provides power to the HMD 102 via the cable 106. In some examples, the box may power an 8-watt to 12-watt system, or a system with higher or lower power requirements. In some examples, the cable 106 may establish a data or communication link between the HMD 102 and the box 104. Figure 1B Further details regarding the HMD assembly 100 are described.

[0047] Figure 1A Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 1A Examples of devices, features, components, and parts are shown.

[0048] Figure 1B A side view of the HMD assembly 100 is shown, showing the box 104 in a number of possible positions and configurations. An advantage of the disclosed deployable box 104 is the ability to position the box 104 in a desired position for the user 111. According to various embodiments described herein, the box 104 can be removed from the HMD 102, which can significantly reduce the weight of the HMD 102 on the user's head 111. Figure 1B An exemplary location of the box 104 is shown in dashed lines. The box 104 can be communicatively coupled to the HMD via a wired or wireless connection. Figure 1B The cable 106 is not shown. However, it should be understood that in each of the possible configurations, the box 104 can be electrically connected to the HMD via the cable 106 or wirelessly.

[0049] In some examples, the case 104 may be removed from the HMD 102 and positioned or attached to the retaining band 110. Figure 5 This configuration is discussed in more detail.

[0050] In some examples, box 104 may be attached to or carried by a portion of the user's body. For example, box 104 may be attached to an armband worn by the user. In some examples, the box may be worn like a necklace, belt attachment, waist bag, or any other wearable accessory. In some examples, box 104 may be sized and shaped to fit in a user's pants pocket.

[0051] In some examples, the box 104 can be set or placed on any suitable object, such as a table, desk, chair, sofa, or floor. Figures 7 to 8C As described in more detail, the box 104 can be used as an input device. Thus, in some examples, the box 104 can be released from the HMD 102 and held by the user, similar to a remote control.

[0052] The box 104 can be inserted into a slot or opening defined by the HMD 102. In some examples, the box 104 can be mounted or attached to an outer surface of the HMD 102. For example, the box 104 can be attached to the front outer surface of the HMD 102 so that the box 104 defines the exterior of the HMD 102 when attached to the HMD 102. Figure 2 Describes further details about HMD components.

[0053] The box 104 may be a companion device that communicates with the HMD 102 via a communication link. The communication link may be a physical connection, such as a wire, or may be a wireless connection, such as Bluetooth, WI-Fi, a proximity sensor, or the like.

[0054] Figure 1B Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 1B Examples of devices, features, components, and parts are shown.

[0055] Figure 2 A schematic block diagram of an HMD assembly 200 is shown. The HMD assembly 200 can be substantially similar to the components described herein, including assembly 200, including some or all of the features thereof.

[0056] It should be understood that for simplicity, Figure 2 Only selected components are shown and described in the drawings. Assembly 200 is not limited to these components and may include additional components not shown or described herein.

[0057] The assembly 200 may include a display unit or HMD 202 and a box 204 electrically connected to the HMD 202 via a cable 206. In some examples, the HMD 202 and the box 204 may communicate wirelessly. The assembly 200 may be modular (i.e., the HMD 202 and the box 204 may be attachable and detachable from each other), as opposed to the box 204 being integrally formed and configured to be permanently attached to the HMD 202. In other words, the assembly 200 may be configured to easily and at will remove the box 204 from the HMD 202.

[0058] The HMD 202 may include a display 208 , a retaining strap 210 , a slot 214 to receive the case 204 , a coupler 216 to physically connect with the case 204 , and an electrical interface 220 to electrically connect with the case 204 .

[0059] The display 208 of the HMD 202 may include an opaque, less-than-transparent, transparent, or translucent screen, including any number of lenses, for presenting image data to the wearer. The HMD 202 may include a headband or retaining strap 210. In some examples, the retaining strap 210 is a band, strap, belt, armband, or other form of support that secures the HMD 202 to the user's head.

[0060] In some examples, the HMD 202 includes a first coupler or attachment interface 216 that engages, attaches, or couples with the box 204. The first coupler 216 can be releasably coupled to the box 204. As described in more detail below, the first coupler 216 can include any suitable attachment mechanism for connecting to the box 204. The first coupler 216 can be a mechanical and / or magnetic attachment interface. In some examples, the first coupler 216 is a recess or groove defined by the box 204 that accommodates and releasably secures the box 204. In some examples, the box can be retained in the recess or groove via an interference fit, a detent feature, a magnetic interaction, or a combination thereof.

[0061] As described herein, the box 204 may include one or more electronic components required by the HMD 202. For example, the box 204 may include a processor 222 and a battery 224. In some examples, the box 204 may include a battery 224. The battery 224 may be the main power source for the HMD 202 and / or the box 204, and may be operable to electrically couple with and power components of the HMD 202 and / or components of the box 204. The battery 224 may be a rechargeable battery, such as a lithium-ion polymer battery. The battery 224 may be completely or entirely positioned within the housing of the HMD 202. In some examples, the battery 224 may be a single unit, or multiple batteries may be used as the main power source for the HMD 202 and / or the box 204.

[0062] By having the ability to remove battery 224 from HMD 202, a larger battery may be used than would otherwise be feasible using a permanent battery in HMD 202. In some examples, battery 224 is the sole or only battery used to power assembly 200. In other examples, battery 224 is an auxiliary or supplemental battery that can be used in conjunction with a battery on HMD 202 to power assembly 200.

[0063] In some examples, the box 204 may include one or more inputs 215, including but not limited to buttons, a touch pad, a directional pad, an analog stick, etc. The input 215 may be located on the exterior of the housing of the box 204. When the user manipulates the input 215, a signal may be transmitted to the HMD 202 (e.g., via the cable 206). In some examples, the signal may be transmitted to the HMD 202 wirelessly. In this way, the box 204 may be used as a remote control for the HMD 202. Figures 7 to 8C Provides further details about the input terminal.

[0064] The box 204 may include an electrical interface 232 to electrically couple with the electrical interface 220 of the HMD 202. The electrical interface 232 may include a plug or electrical connector for establishing an electrical connection between the box 204 and the HMD 202. Specifically, the electrical interface 232 may be in electrical communication with the electronic components of both the HMD 202 and 204. Power and / or data may be transmitted between the HMD 202 and the box 204. The electrical interface 232 may transmit power / data from the HMD 202 to the box 204 via the cable 206 or via a direct connection. The electrical interface 232 may be a direct electrical connection. In some examples, the electrical interface 232 may establish an electrical connection directly with the HMD 202. In some examples, the electrical interface 232 may include a cable or wire connected to the HMD 202.

[0065] In some examples, the box 204 includes a second coupler or attachment interface 230 that engages, attaches, or couples with the HMD 202. The second coupler 230 can be releasably or fixedly coupled to the HMD 202. As described in more detail below, the second coupler 230 can include any suitable attachment mechanism for connecting to the HMD 202. The second coupler 230 can be a mechanical and / or magnetic attachment interface. In some examples, the second coupler 230 can engage with a recess or groove defined by the HMD 202. Further details about the attachment interface and couplers are provided below.

[0066] In some examples, the cartridge 204 may include an output component 233. Figure 2Only one output component 233 is shown in the figure, but it should be understood that the output component 233 may include multiple physically different or combined output terminals. The output component may include various electronic components (e.g., audio components, light modules, tactile components, etc.) that produce outputs. The output component 233 can alert the user to the condition or status of the HMD 202 and / or the box 204. In some examples, the output component 2233 can signal whether the box 204 is connected (physically and / or electrically) to the HMD 202.

[0067] In some examples, the case 204 may include a cable manager 228 (also referred to as a cable management system or cable organizer). The cable manager 228 may organize, hold, or otherwise secure the cable 206 of the assembly 200. The cable may be long to accommodate situations where the accessory is not near the HMD 202 (i.e., not in the case 204). The length of the cable may interfere with the use of the HMD 202. Therefore, the cable manager 228 may be used to keep and store the cable 206 in an orderly manner. Figure 12 to Figure 13 Cable management systems are discussed in more detail.

[0068] In some examples, cartridge 204 may include sensor unit 240. Sensor unit 240 may detect or determine one or more aspects of the operating environment or physical environment of assembly 200. Figure 2 Only one sensor unit 240 is shown in the figure, but it should be understood that the sensor unit 240 may include multiple physically different or combined sensors. For example, the sensor unit 240 may include one or more of a contact sensor, a pressure sensor, a proximity sensor, a camera, a microphone, an infrared receiver, a global positioning system unit, a gyroscope sensor, an accelerometer, a capacitive sensor, a biometric sensor, a magnetometer, a radar unit, a lidar unit, an ultrasonic unit, a temperature sensor, or any other sensor capable of detecting or determining one or more aspects or conditions of the operating environment of the component 200.

[0069] In a particular example, the sensor unit 240 can determine whether the box 204 is close to or attached to the HMD 202. The sensor unit 240 can be operably coupled to the box 204 to cause the box 204 to perform one or more actions. For example, upon determining that the user is attempting to attach the box 204 to the HMD 202, the sensor unit 240 can generate a signal that triggers the first coupler 214 to attach to the box 204. In some examples, the box 204 includes an actuator that reacts to the placement of the box 204 in / on the mount, thereby causing the first coupler 214 to secure the box 204.

[0070] Figure 2Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 2 Examples of equipment, features, components and parts shown.

[0071] Figure 3 A cross-sectional side view of cartridge 304 is shown. Cartridge 304 may be substantially similar to cartridges described herein, including cartridges 104 and 204, including some or all of their features. Cartridge 304 may be removably attached to an HMD.

[0072] The box 304 may include one or more electronic components disposed within an internal volume 336 defined by a housing 334. For example, the box 304 may include a processor 322 and a battery 324 disposed or positioned within an internal volume 336 defined by the housing 334 of the box 304. In some examples, the box 304 includes a fan 326 positioned within the internal volume 336. The fan 326 may include one or more blades 327 driven by a motor 329 to generate an airflow to reduce the temperature of the internal volume 336. As described in more detail below, the fan 326 may be used to dissipate heat from one or both of the box 304 and the HMD. In some examples, the box 304 may include an integrated circuit 323, such as a system on a chip (SOC). The box 304 may include a memory 325, such as a NAND flash memory or any other suitable storage component.

[0073] In some examples, the case 304 may include a haptic member 338 positioned within the case's interior volume 336. The haptic member 338 may generate tactile or tactile feedback to the user. The haptic member 338 is a tactile actuator and may generate tactile feedback that will be felt by the user's head and / or hand. In some examples, the haptic member 338 may be used to generate an audible output, such as a buzzing sound, that may be heard by the user.

[0074] In some examples, the box 304 may include at least one inertial measurement unit 340 positioned within the interior volume 336. The inertial measurement unit (IMU) 340 may detect movement of the box 304 and may determine a position, attitude, or orientation of the box 304. The inertial measurement unit 340 may include at least one of an accelerometer, a gyroscope, or a magnetometer. In some examples, the box 304 may include multiple IMUs 340. For example, the box 304 may include a first IMU positioned at a first end of the box 304, and a second IMU positioned at a second, opposite end of the IMU.

Similarly, any of the features, components and / or parts shown or described with reference to other figures (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 3 Examples of equipment, features, components and parts shown.

[0076] Figure 4 A front view of HMD assembly 400 is shown. HMD assembly 400 can be substantially similar to assemblies described herein, including assemblies 100 and 200, including some or all features thereof.

[0077] The HMD assembly 400 may include an HMD 402 and a box 404. The HMD 402 and the box 404 may be electrically coupled via a cable 406. The HMD 402 may define a recess or slot 414 defined by a housing of the HMD 402. Figure 4 As shown, the outline of the slot 414 is depicted with dashed lines to indicate that the slot 414 is positioned in the HMD 402, such as sandwiched between two major surfaces or faces of the HMD 402. The slot 414 can be sized and shaped to removably receive the cartridge 414. The slot 414 can have a shape that substantially matches the shape of the cartridge 414.

[0078] In some examples, the HMD 402 may include a notch or groove 405a that is sized, shaped, and positioned to accommodate a user's nose. Similarly, the box 404 may include a notch or groove 405b that is sized, shaped, and positioned to accommodate a user's nose. The groove 405a in the HMD 402 and the groove 405b in the box 404 may be substantially similar or identical, so that when the box 404 is inserted into the slot 414, the grooves 405a, 405b are aligned to leave room for the user's nose. Additionally, the groove 405b in the box 404 may be used as an orientation indicator to help the user know which way to insert the box 404 into the HMD 402.

[0079] In some examples, cable 406 can be detached from HMD 402 and can be inserted into a different electronic device (such as a display, monitor, laptop computer, or a different HMD). Thus, box 404 can be operated as a portable computer. In some examples, cable 406 can be removed from box 404 and attached to different computing elements. Cable 406 can be completely removed from both box 404 and HMD 402. For example, when box 404 is positioned in HMD 402, electrical terminals or contacts on box 404 can be electrically engaged with corresponding contacts in HMD 402 to establish an electrical connection to transmit data and / or power, thereby eliminating the need for cable 406. Therefore, when box 404 is inserted into slot 414 of HMD 404, cable 406 can be completely removed from HMD assembly 400.

[0080] Figure 4 Any of the features, components and / or parts shown (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 4 Examples of devices, features, components, and parts are shown.

[0081] Figure 5 A side view of an HMD assembly 500 worn by a user 511 is shown. HMD assembly 500 may be substantially similar to, including some or all of the features of, assemblies described herein, including assemblies 100 through 800. Assembly 500 may include HMD 502, retaining strap 510, and case 504.

[0082] The HMD 502 may include a slot 514 to accommodate the box 504. The box 504 may be removed or unfolded from the slot 504 to reduce the weight of the HMD 502 in front of the user's face. By removing the box 504 from the HMD 502, the weight of the HMD 502 on the user's face is greatly reduced, allowing for increased comfort and wearing time.

[0083] In addition, the removable box 504 can be used as a counterweight by unfolding the box 504 outside the HMD 502 and attaching the box 504 to the retaining belt 510. In some examples, the box 504 can be mounted to the retaining belt 510. For example, the box 504 can be attached to the retaining belt 510 so that the box 504 is positioned behind the head of the user 511. By positioning the box 504 opposite to the HMD 502, the center of mass of the assembly 500 can be shifted from the front of the user's head to the middle or center of the user's head, thereby improving weight distribution and enhancing user comfort. In some examples, the weight of the HMD 502 and the weight of the box 504 are substantially similar. For example, the HMD 502 and the box 504 can each weigh approximately 150 grams to 300 grams.

[0084] In some examples, the retaining band 510 may include an attachment interface for attaching the box 504 to the retaining band 510. In other words, the mounting piece can be retrofitted onto an existing retaining band without modifying the existing retaining band. In some examples, the retaining band 510 includes a separate component for coupling with the mounting piece. In some examples, the mounting piece is incorporated into the retaining band 510 as an integral component of the retaining band 510. In some examples, the fabric of the retaining band 510 secures the box 504. For example, the retaining band 510 can be used as a sleeve or sheath for at least some of the boxes 504.

[0085] In some examples, the retaining band 510 can include an integrated cable management system for managing the power cable 506. For example, the retaining band 510 can include an electrical connector or access port 520 that can establish an electrical connection with the connector 532 of the box 504. Thus, the cable 506 can establish an electrical connection between the HMD 502 and the box 504. The cable 506 can be removably or permanently connected to the HMD 502 and / or the retaining band 510.

[0086] In some examples, the cable 506 may be attached to the retaining band 510, or may travel along the retaining band when the box 504 is attached to the retaining band 510. In some examples, a cable management system may be used to take up slack from the cable 506. For example, the retaining band 510 may include a hook or retainer to secure excess slack in the cable 506. The retaining band 510 may include a reel or spool to wind the cable 506.

[0087] like Figure 5 As shown, the slot 514 is accessible from the bottom of the HMD 502. In other words, an opening or aperture is defined by the bottom of the HMD 502 so that the cartridge 504 can be inserted into the HMD 502 by pushing the cartridge 504 upward into the slot 514. Likewise, to eject the cartridge 504 from the HMD 502, the cartridge 504 is released to travel downward (e.g., Figure 5514). To eject or release the cartridge 504 from the slot 514, the cartridge 504 may rely solely on the downward force of gravity, or a biasing element (such as a spring) may assist in ejecting the cartridge 504 from the slot 514. In some examples, the biasing element may selectively hold the cartridge 504 in the slot 514. In other words, the biasing element may selectively bias the cartridge 504 into or out of the slot 514 as desired. As shown and described herein, other configurations for inserting and ejecting the cartridge from the HMD are possible, including but not limited to slots located on the sides of the HMD or slots located on the top of the HMD.

[0088] In some examples, the slots 514 allow the HMD 502 to cool without the assistance of fans. Many conventional HMDs require onboard fans, which increase the overall thickness and weight of the device. Without fans, the heat of a typical system is too high to operate under steady-state contact conditions. Without the use of fans on conventional HMDs, the maximum temperature of system components may be exceeded. However, by providing the slots 514 in the HMD 502, there is better cooling of the system by allowing heat to be better dissipated from the internal components via the slots 514. Therefore, in the event that the box 504 is removed from the HMD 502, there is no need to install a fan on the HMD 504. In addition, as described herein, when the box 504 is in the HMD 502, the box 504 may include an onboard fan to help reduce heat within the box 504 and the HMD 502. Reference is made below to Figure 6 Describes further details about HMD components.

[0089] Figure 5 Any of the features, components and / or parts shown (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 5 Examples of equipment, features, components and parts shown.

[0090] Figure 6 A cross-sectional side view of an HMD assembly 600 is shown including a deployable cartridge 604. HMD assembly 600 can be substantially similar to assemblies described herein, including assemblies 100, 200, 400, and 500, including some or all features thereof.

[0091] In some examples, HMD assembly 600 can include display 645 to provide visual output to user eye 611. When box 604 is positioned in HMD 602, display 645 can be located between box 604 and user eye 611.

[0092] The HMD assembly 600 may include a removable or deployable case 604, as described herein. The HMD 602 ​​may include a frame or housing 647 defining one or more openings 614a, 614b through which the case 604 may be inserted into or removed from the HMD 602. For example, the first opening 614a may be located at the top of the HMD 602, as described herein. Figure 6 614a in the top of the HMD 602, the box 604 is less likely to accidentally fall out of the HMD 602. In some examples, the HMD 602 ​​may include both the top opening 614a and the bottom opening 614b. Thus, the HMD 602 ​​may define a through slot for selectively inserting or removing the box 604 into or from the openings 614a, 614b. In addition to providing easy and convenient access to the box 604, the through opening also improves air flow and cooling of the HMD assembly 600.

[0093] The case 604 may include a coupling member 630 to engage with a corresponding coupling member 616 on the HMD 602. In some examples, the coupling member 630 may include a magnet or magnetic attraction component located on the exterior or interior of the case 604. Similarly, the coupling member 616 may include a magnet or magnetic attraction component that is positioned to magnetically couple with the coupling member 630 of the case 604 when the case is inserted into the HMD 602. In some examples, the coupling member 616 may be fixed to the HMD 602, such as mounted to the housing 647. In some examples, the case 604 and the HMD 602 ​​may each include a plurality of magnets to secure the case 604 within the HMD 602. The strength of the magnets 616, 630 may be selected or adjusted to be strong enough to securely hold the case 604 within the HMD 602 ​​when subjected to typical movement of the HMD 602, but weak enough to be overcome by the user to remove the case 604.

[0094] In some examples, when inserted into the HMD 602, the box 604 can be positioned or sandwiched between the display 645 and other electronic components or the front of the HMD 602. As described herein, the box 604 can include a cooling fan to generate airflow to reduce the temperature of the interior of the box 604 and / or the interior of the HMD 602. In some examples, the box 604 can be intentionally positioned to allow ideal airflow to the internal components of the HMD 602 ​​when inserted, and to allow ideal passive airflow or "breathing" of the HMD 602 ​​when the box 604 is removed. Figure 7 Further details regarding the functionality of the box are described.

[0095] Figure 6Any of the features, components and / or parts shown (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 6 Examples of devices, features, components, and parts are shown.

[0096] Figure 7 A perspective view of a cartridge 704 including an input element is shown. The cartridge 704 can be substantially similar to cartridges described herein, including cartridges 104, 204, 304, 404, 504, and 604, including some or all of the features thereof.

[0097] The deployable box described herein may include several advantages, such as reducing the weight of the HMD on the user's head. Additionally, once the box is removed, it can be advantageously used as an input device for the HMD components. HMDs typically rely on user input to operate. User input is typically provided through buttons, joysticks, touch screens, or other input components. Due to limited substrate real estate and non-ideal ergonomics of the input terminals on the headset, it may be problematic to position the input terminals on the headset itself. Therefore, one solution is to provide the input terminals on a removable box so that the user can manipulate the box as a remote control.

[0098] In some examples, the box 704 may include one or more inputs, including but not limited to a button 717 and a touch pad 715. The inputs 715, 717 may be located on the exterior of the housing 736 of the box 704. When the user manipulates the inputs 715, 717, a signal may be transmitted to the HMD via the cable 706. In some examples, the signal may be transmitted to the HMD wirelessly.

[0099] In some examples, the box 704 may include one or more vents 741 to allow airflow through the interior of the box 704. The vents 741 may be positioned in a predetermined position to avoid being blocked when held by a user's hand. In addition, the position of the vents 741 may be intentionally positioned so as not to be blocked or clogged when the box 704 is inserted into the HMD. In some examples, the size and shape of the box 704 may be set to allow a comfortable and ergonomic feel when held by a user and used as a remote control. For example, the box 704 may be curved or reinforced to conform to a typical user's hand. The vents 741 may include perforations or holes in the housing 736.

[0100] In some examples, box 704 may include components designed to provide feedback to the user's hand. For example, box 704 may include a haptic engine to provide tactile or tactile feedback to the user's hand. In some examples, box 704 includes an IMU that can be used to receive orientation input from a user moving box 704. For example, a user can use box 704 as a controller to play a video game. The user can tilt the controller left or right to produce similar results in the video game. The movement of box 704 can be detected by an onboard IMU located in box 704. FIG. 8A to FIG. 8C Further details regarding the functionality and configuration of the box are described.

[0101] Figure 7 Any of the features, components and / or parts shown (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including their settings and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 7 Examples of devices, features, components, and parts are shown.

[0102] Fig. 8A A side view of a foldable box in a folded state is shown.Box 804 may be substantially similar to boxes described herein, including boxes 104, 204, 304, 404, 504, 604, and 704, including some or all of the features thereof.

[0103] In some examples, the box 804 may include a first portion 807 and a second portion 809. The first portion 807 may be adjustable or movable relative to the second portion 809. For example, the box 804 may be foldable. The first portion 807 may be pivotally connected to the second portion 809 via a hinge 813. Fig. 8A The case 804 is shown in a folded, closed, or collapsed configuration. In some examples, the case 804 can be inserted into the HMD when in the folded configuration.

[0104] Figure 8B A side view of the foldable box 804 is shown in a partially opened configuration, and Figure 8CA front view of a box 804 in an open or unfolded configuration is shown. In some examples, when the box 804 is in a folded configuration, the inputs 815, 817 may be covered or hidden. Then, when the box 804 is opened, the inputs 815, 817 may be uncovered or exposed. In other words, when the box 804 is folded, the inputs 815, 817 may be positioned in the interior of the box 804, and when the box 804 is unfolded, the inputs 815, 817 may be positioned on the exterior of the box 804. In some examples, the first portion 807 may be completely or completely separated from the second portion 809. The first portion 807 and the second portion 809 may include similar electronic components. For example, the first portion 807 and the second portion 809 may both include batteries, processors or other components. In some examples, the first portion 807 and the second portion 809 do not share components. For example, the battery may be positioned in the first portion 807, and the processor is positioned in the second portion 809.

[0105] The HMD assembly may include multiple boxes. In some examples, the assembly includes a primary box (e.g., a mother device) and a secondary box or companion box (e.g., a child device). The primary box and the secondary box may communicate via Bluetooth. In some examples, both the primary box and the secondary box may be attached to or plugged into the HMD. In some examples, the primary box and the secondary box may be attached to each other before integration with the HMD. In some examples, the primary box and the secondary box may be independently integrated with the HMD (i.e., separate from each other). Fig. 9 Further details regarding the features and functionality of the cartridge are described.

[0106] Fig. 8A , Figure 8B and / or Figure 8C Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein.

Fig. 8A , Figure 8B and / or Figure 8C Examples of equipment, features, components and parts shown.

[0107] Fig. 9 A cross-sectional top view of cassette 904 is shown including fan 926. Cassette 904 may be substantially similar to cassettes described herein, including cassettes 104, 204, 304, 404, 504, 604, 704, and 804, including some or all of the features thereof.

[0108] In some examples, the box 904 may include at least one fan 926. The fan 926 may include one or more blades 927 driven to rotate about a central axis by a motor 929. The fan 926 may generate airflow in / around the box 904 to dissipate heat generated by the electronic components of the box 904 and / or the HMD. Fig. 9 As shown, the box 904 can include at least two fans 926. The fans 926 can have the same or different sizes. The fans 926 can be positioned symmetrically or asymmetrically relative to each other in the box 904.

[0109] For clarity, Fig. 9 The fan 926 is shown uncovered, however, the fan 926 can be substantially covered by the housing 934 of the box 904. The fan 926 can be in fluid communication with ambient air outside the box 904 through vents and / or exhaust ports in the housing 934. In some examples, the fan 926 can be used as a haptic engine. For example, the fan 926 can generate vibrations that can be felt by the user as tactile feedback. The blades 927 can be off-center or eccentric so that vibrations are generated when the blades 927 rotate. In some examples, one of the blades 927 can be heavier or differently shaped than the other blades, thereby causing a vibration output.

[0110] In some examples, tactile vibrations can be generated by moving a block or protrusion into the path of a fan so that the fan impacts the block as it rotates. Repeated impacts between the block and the blades can generate a sense of vibration. In response to user input or in response to the condition of the media being displayed on the HMD, the block can be moved into contact with the fan. In some examples, tactile feedback can be generated by increasing the RPM of the fan.

[0111] Reference below Fig.10 Describes further details about the box.

[0112] Fig. 9 Any of the features, components and / or parts shown (including their arrangements and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including their arrangements and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Fig. 9 Examples of devices, features, components, and parts are shown.

[0113] Fig.10 A top view of a cartridge including a vent is shown.Cassette 1004 can be substantially similar to cartridges described herein, including cartridges 104, 204, 304, 404, 504, 604, 704, 804, and 904, including some or all of the features thereof.

[0114] In some examples, the box 1004 may include one or more vents 1041 defined by the housing 1034 of the box 1004. The vents 1041 may provide an airflow path between the interior of the box 1004 and the surrounding environment. It is a priority to prevent particles such as dust or debris from entering the internal volume of the box 1004. There are challenges in allowing sufficient airflow while preventing particles from entering. To address this challenge, the box 1004 may include a door or baffle 1043 that is movable to open or close the vent 1041. In some examples, when the box 1004 is not actively cooled via a fan, the baffle 1043 may be closed. Then, when the box 1004 is actively cooled or ventilated, the baffle 1043 may be opened. In some examples, the baffle 1043 may be electromechanically coupled to an actuator that moves the baffle 1043.

[0115] In some examples, the position of the baffle 1043 is based on whether the cartridge 1004 is inserted into or removed from the HMD. For example, when the cartridge 1004 is in the HMD, particle ingress may be less of a concern because the cartridge 1004 is located in a relatively isolated and sterile environment within the HMD. Additionally, when the cartridge 1004 is in the HMD, the need for cooling, and therefore the need for the vent 1041 to be opened, may be greater due to the increased heating caused by the cartridge 1004 being located within the HMD.

[0116] In some examples, the action of inserting the box 1004 into the HMD may cause the baffle 1043 to open. For example, when the box 1004 is inserted into the HMD, a cam, actuator, or protrusion that is structurally linked to the baffle 1043 may be engaged by a portion of the HMD, causing the baffle 1043 to open. When the box 1004 is removed from the HMD, a similar mechanism (such as a cam or protrusion) may engage a component of the HMD to close the vent 1043. In some examples, the vent 1043 is biased (e.g., by a spring) to be in an open or closed configuration. In some examples, when the box 1004 is positioned in the HMD, the vent 1043 of the box 1004 may be strategically positioned to align with certain components or airflow paths in the HMD. Similarly, when the box 1004 is removed from the HMD, additional airflow paths or vents within the HMD may be opened to allow for increased cooling. Refer to the following Fig.11 Further details regarding the features and functionality of the cartridge are described.

[0117] Fig.10 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Fig.10Examples of devices, features, components, and parts are shown.

[0118] Fig.11 A top view of a cartridge including a vent is shown.Cartridge 1104 can be substantially similar to cartridges described herein, including cartridges 104, 204, 304, 404, 504, 604, 704, 804, 904, and 1004, including some or all of the features thereof.

[0119] In some examples, the box 1104 may include one or more vents 1141 defined by the housing 1134 of the box 1104. The vents 1141 may provide an airflow path between the interior of the box 1104 and the surrounding environment. Preventing particles, such as dust or debris, from entering the interior volume of the box 1104 is a priority. There are challenges in allowing sufficient airflow while preventing particles from entering. To address this challenge, the box 1104 may include a screen or mesh 1143 that prevents particles from entering while still allowing airflow. Fig.12 Further details regarding features of HMD components are described.

[0120] Fig.11 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Fig.11 Examples of devices, features, components, and parts are shown.

[0121] Fig.12 A front view of an HMD assembly 1200 including a cable management system is shown. HMD assembly 1200 can be substantially similar to assemblies described herein, including assemblies 100, 200, 400, 500, and 600, including some or all features thereof.

[0122] The HMD assembly 1200 may include an HMD 1202 and a box 1204. The HMD 1202 and the box 1204 may be electrically coupled via a cable 1206. The HMD 1202 may define a recess or slot 1214 defined by a housing of the HMD 1202. Fig.12 As shown, the outline of the slot 1214 is depicted with a dashed line to indicate that the slot 1214 is positioned in the HMD 1202, such as between two major surfaces or faces of the HMD. The slot 1214 can be sized and shaped to removably accommodate the cartridge 1214. The slot 1214 can have a shape that substantially matches the shape of the cartridge 1214.

[0123] The box 1204 may include a cable management system for gathering, collecting or otherwise organizing the slack in the cable 1206. In some examples, the cable management system includes one or more posts 1228 around which the cable 1206 can be wound. The size and shape of the slot 1214 can be set to accommodate the cable 1206 when the box 1204 is inserted into the slot 1214. The post 1228 can be positioned on the box 1204 so that when the box 1204 is inserted into the HMD 1202, the wound cable 1206 is hidden in the HMD 1202. In addition to conveniently storing the slack in the cable 1206, the cable management system also provides a pleasing aesthetic by partially or completely hiding the cable. The post 1228 also allows the user to release only the amount of slack required at a particular moment. For example, the cable 1206 may be 10 feet long, however, the user may only need 5 feet long. Thus, the remaining 5 feet of cable 1206 can remain wrapped around pole 1228 where it is less likely to become tangled or obstruct the user. Fig.12 1204, but it should be understood that other methods of collecting cables 1206 are conceivable and possible using this method. For example, the cables 1206 can be bundled and stored in the slot 1214 between the HMD 1202 and the box 1204.

Likewise, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included, alone or in any combination, in any other examples of devices, features, components, and parts shown in other figures described herein. Fig.12 Examples of devices, features, components, and parts are shown.

[0125] Reference below Fig.13 Further details regarding features of HMD components are described.

[0126] Fig.13 A cross-sectional side view of a head-mountable system including a cable management system is shown.

[0127] HMD assembly 1300 may be substantially similar to the HMD assembly 100, 200, 400, 500, 600, and

[0128] 1200, including some or all of its features.

[0129] The HMD assembly 1300 may include a removable or deployable case 1304, as described herein. The HMD 1302 may include a frame or housing 1347 defining one or more openings 1314 through which the case 1304 may be inserted into or removed from the HMD 1302.

[0130] The case 1304 may include a coupling member 1330 to engage with a corresponding coupling member 1316 on the HMD 1302. The coupling members 1330, 1316 may include any suitable mechanical attachment mechanism, including clips, fasteners, threads, detents, protrusions, etc. In some examples, the coupling members 1330, 1316 form a push-push mechanism to release and attach the case 1304. In some examples, the coupling member 1330 may include a magnet or magnetic attraction component located on the exterior or interior of the case 1304. Similarly, the coupling member 1316 may include a magnet or magnetic attraction component that is positioned to magnetically couple with the coupling member 1330 of the case 1304 when the case is inserted into the HMD 1302. In some examples, the coupling member 1316 may be fixed to the HMD 1302, such as mounted to the housing 1347. In some examples, the case 1304 and the HMD 1302 may each include a plurality of magnets to secure the case 1304 within the HMD 1302. The strength of the magnets 1316, 1330 may be selected or adjusted to be strong enough to hold the case 1304 securely within the HMD 1302 when subjected to typical movement of the HMD 1302, but weak enough to be overcome by the user to remove the case 1304.

[0131] In some examples, the HMD assembly 1300 includes electrical connectors 1316, 1330. When the box 1304 is positioned in the HMD 1302, the electrical terminals or contacts 1330 on the box 1304 can be electrically engaged with the corresponding contacts 1316 in the HMD 402 to establish an electrical connection to transfer data and / or power. In order to establish a connection between the HMD 1302 and the inserted box 1304, any suitable plug for establishing a data connection can be used, including a USB connector, an HMDI connector, a DisplayPort connector, a VGA connector, etc. It should be understood that by electrically connecting the inserted box 1304 to the HMD 1302, the cable 1306 can be removed. In some examples, the corresponding cable connection interfaces on the box 1304 and the HMD 1302 are configured to engage each other when the cable 1306 is removed.

[0132] In some examples, when inserted into HMD 1302, box 1304 may be positioned or sandwiched between display 1345 and other electronic components or the front face of HMD 1302. As described herein, box 1304 may include a cooling fan to generate airflow to reduce the temperature of the interior of box 1304 and / or the interior of HMD 1302. In some examples, box 1304 may be intentionally positioned to allow ideal airflow to the internal components of HMD 1302 when inserted, and to allow ideal passive airflow or "breathing" of HMD 1302 when box 1304 is removed.

[0133] The box 1304 may include a cable management system. For example, the box 1304 may include one or more posts 1328. The posts 1328 may be located on any side or surface of the box 1304. Fig.13 In the example of FIG. 1 , post 1328 is shown on the side of box 1304 (eg, Fig.13 As shown, when the cable 1306 is wound and the box 1304 is inserted into the HMD 1302, the cable 1306 can be substantially or completely positioned or hidden within the HMD 1302.

[0134] Fig.13 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included, alone or in any combination, in any other examples of devices, features, components and parts shown in other figures described herein. Likewise, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included, alone or in any combination, in any other examples of devices, features, components and parts shown in other figures described herein.

[0135] To the extent applicable to the present technology, the collection and use of data obtained from various sources may be used to improve the delivery of inspirational content or any other content that may be of interest to users. The present disclosure contemplates that in some instances, such collected data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data may include demographic data, location-based data, phone numbers, email addresses, ID, home address, data or records related to the user's health or fitness level (e.g., vital sign measurements, medication information, exercise information), date of birth, or any other identifying or personal information.

[0136] The present disclosure recognizes that the use of such personal information data in the present technology can be used to benefit users. For example, the personal information data can be used to deliver targeted content that users are more interested in. Therefore, the use of such personal information data enables users to have planned control over the content delivered. In addition, the present disclosure also anticipates other uses of personal information data that benefit users. For example, health and fitness data can be used to provide insights into the user's overall health status, or can be used as positive feedback to individuals who use technology to pursue health goals.

[0137] The disclosure anticipates that entities responsible for the collection, analysis, disclosure, transmission, storage or other purposes of such personal information data will comply with sound privacy policies and / or privacy measures. Specifically, such entities should implement and adhere to the use of privacy policies and practices that are recognized as meeting or exceeding the industry or government requirements for maintaining the privacy and security of personal information data. Such policies should be easy for users to access and should be updated as changes in the collection and / or use of data occur. Personal information from users should be collected for legal and reasonable entity purposes and should not be shared or sold outside these legal purposes. In addition, such collection / sharing should be carried out after receiving the informed consent of the user. In addition, such entities should consider taking any necessary steps to protect and safeguard access to such personal information data, and ensure that other entities with access to personal information data comply with their privacy policies and procedures. In addition, such entities can subject themselves to third-party assessments to prove that they comply with widely accepted privacy policies and practices. In addition, policies and practices should be adapted to specific types of personal information data collected and / or accessed, and to applicable laws and standards including considerations of special jurisdictions. For example, in the United States, the collection or acquisition of certain health data may be governed by federal and / or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); while health data in other countries may be subject to other regulations and policies and should be handled accordingly. Therefore, different privacy measures should be advocated for different types of personal data in each country.

[0138] Regardless of the foregoing, the present disclosure also contemplates implementation schemes in which users selectively block the use or access of personal information data. That is, the present disclosure contemplates hardware elements and / or software elements to prevent or block access to such personal information data. For example, with respect to an advertising delivery service, the technology of the present invention may be configured to allow a user to choose to "opt in" or "opt out" to participate in the collection of personal information data at any time during or after registration for the service. In another example, a user may choose not to provide emotion-related data for a target content delivery service. In another example, a user may choose to limit the length of time that emotion-related data is retained, or completely prohibit the development of basic emotional conditions. In addition to providing "opt-in" and "opt-out" options, the present disclosure also contemplates providing notifications related to access or use of personal information. For example, a user may be notified that their personal information data will be accessed when downloading an application, and then the user may be reminded again just before the personal information data is accessed by the application.

[0139] In addition, it is the intention of the present disclosure that personal information data should be managed and processed in a manner that minimizes the risk of unintentional or unauthorized access or use. Once the data is no longer needed, the risk can be minimized by limiting the collection of data and deleting the data. In addition, and when applicable, including in certain health-related applications, data de-identification can be used to protect the privacy of users. De-identification can be facilitated by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of stored data (e.g., collecting location data at the city level rather than at the address level), controlling how the data is stored (e.g., aggregating data between users), and / or other methods when appropriate.

[0140] Thus, while the present disclosure broadly covers the use of personal information data to implement one or more of the various disclosed embodiments, the present disclosure also contemplates that various embodiments may also be implemented without access to such personal information data. That is, various embodiments of the present technology will not fail to function properly due to the lack of all or a portion of such personal information data. For example, content may be selected and delivered to a user by inferring preferences based on non-personal information data or an absolute minimum amount of personal information, such as content requested by a device associated with the user, other non-personal information available to a content delivery service, or publicly available information.
