[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 792,443, filed April 22, 2025, entitled “WEARABLE ELECTRONIC DEVICE,” the entire disclosure of which is incorporated herein by reference. Technical Field

[0002] This disclosure generally relates to electronic devices. More specifically, this disclosure relates to head-mounted electronic devices. Background Technology

[0003] Various components of a head-mounted display (HMD), such as a display screen, viewing frame, mounting arms, speakers, batteries, waveguides, and others, work together to provide immersive alternative reality, mixed reality, and virtual reality experiences. These components are typically housed within the HMD. These components can add significant weight to the HMD. During prolonged use, this weight can lead to discomfort. In some traditional configurations, weight is distributed via a strap through a pad on the HMD for the user's nose, mounting arms that distribute weight to the user's ears, etc. HMDs can be used in a variety of environments and during a variety of activities. These scenarios can range from working in an office to hiking or mountain biking outdoors. However, the weight of the HMD can cause discomfort during extended use. Therefore, a lighter HMD is needed to increase user comfort during prolonged use. Summary of the Invention

[0004] In at least one example of this disclosure, a head-mounted display device (HMD) may include: a first display assembly, which may include a first display and a first housing surrounding the first display; a second display assembly, which may include a second display and a second housing surrounding the second display; a first fixing arm extending from the first housing; and a second fixing arm extending from the second housing. The HMD may also include: a data transmission cable electrically coupled to the first display and extending through the first fixing arm; and an electrical port coupled to the first and second displays via the data transmission cable, the data transmission cable extending uninterruptedly between the electrical port and the first display, and the electrical port being connectable to an external computing unit capable of controlling the visual output of the first and second displays.

[0005] In at least one example, the HMD does not contain computing components. In at least one example, the external computing unit includes a processor and is capable of transmitting all control signals received by the first and second displays via data transmission cables. In at least one example, the first and second display assemblies are passively cooled. In at least one example, a first housing defines a first internal volume, and a second housing defines a second internal volume isolated from the first internal volume by the first and second housings. The HMD also includes a bridging member extending between and connecting the first and second housings, and the data transmission cables extend through the bridging member. In at least one example, the HMD also includes power cables extending through a second mounting arm and electrically coupled to the second and first displays.

In one example, the wearable display device may further include a data transmission cable electrically coupled to the first display screen and extending through a first temple arm. In one example, the wearable display device may further include an electrical port electrically coupled to the first and second displays screens via the data transmission cable, the data transmission cable extending between the electrical port and the first display screen, without electrically coupling to any intermediate processing components between the electrical port and the displays screens. In at least one example, neither the first display module nor the second display module includes a cooling fan. In at least one example, the first and second housings may include vents. In at least one example, the wearable display device may further include a bridging member extending between the first and second housings to separate and couple the first and second housings.

[0008] In another example of this disclosure, the HMD may include a first display assembly, which may include a first display, a first housing surrounding the first display and defining a first outer surface, a first lens coupled to the first housing, and a first cover coupled to the first housing opposite to the first lens, with the first display disposed between the first lens and the first cover. The HMD may also include a second display assembly, which may include a second display, a second housing surrounding the second display and defining a second outer surface separate from and isolated from the first outer surface, a second lens coupled to the second housing, and a second cover coupled to the second housing opposite to the second lens, with the second display disposed between the second lens and the second cover. The first display may block light from passing between the first lens and the first cover, and the second display may block light from passing between the second lens and the second cover.

[0009] In at least one example, the first cover and the second cover are opaque. In at least one example, the HMD may further include a bridging member extending between and connecting the first housing and the second housing, a first fixing arm extending from the first housing, and a second fixing arm extending from the second housing. In at least one example, the HMD may further include a data transmission cable extending through the first fixing arm and electrically coupled to the first display and the second display, and a power cable extending through the second fixing arm and electrically coupled to the first display and the second display. Attached Figure Description

[0010] This disclosure will be readily understood from the following detailed description taken in conjunction with the accompanying drawings, in which the same reference numerals denote the same structural elements: Figure 1 An isometric view illustrating an example of a head-mounted device (HMD); Figure 2A A top view of an example HMD is shown; Figure 2B This is a front view of an example HMD; Figure 3A The example of the front equiaxed portion of an HMD is shown; Figure 3B An example of the rear isometric portion of an HMD is shown; Figure 4A An exploded view of an example HMD is shown; Figure 4B Examples are given by Figure 2B A cross-sectional view of an example HMD cut by the cutting line AA; and Figure 5 A side view of an example HMD is shown. Detailed Implementation

[0011] 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 single preferred embodiment. Rather, it is intended to cover alternatives, modifications, and equivalents that may be included within the substance and scope of the described embodiments as defined by the appended claims.

[0012] This disclosure relates generally to electronic devices. More specifically, this disclosure relates to head-mounted devices (HMDs). HMDs can be worn on a user's head to provide immersive experiences in virtual reality (VR), augmented reality (AR), and mixed reality (MR). HMDs can be used in a variety of different environments and during a variety of different activities. These scenarios can be working in an office or going outdoors for mountain biking or hiking. For example, if a user does not have access to a computer or computer monitor, the user can wear an HMD in a non-office environment and complete work using the HMD. In this example, the HMD can display multiple computer monitors to the user as if the user were in an office environment. In another example, a user can wear an HMD to watch a sporting event as if they were sitting on the floor of a stadium while they were in the comfort of their own home. However, current HMDs include various components (such as a display screen, viewing frame, mounting arms, speakers, batteries, waveguides, and other components) that are typically housed within the HMD. These components can add significant weight to the HMD worn on the user's head. This can lead to user fatigue after prolonged use. Therefore, users cannot wear an HMD all day or during a typical eight-hour work shift without feeling fatigued or uncomfortable. The numerous components also require energy storage from the battery, which can increase the device's weight.

[0013] The following disclosure relates to a lightweight HMD that can be worn by a user during an eight-hour work shift or throughout the day. In at least one example, the HMD may be free of computing and cooling components, thereby limiting the required onboard battery capacity and reducing the overall weight of the device. Without the added weight of computing components and the cooling components required for computing, the weight of the HMD is significantly reduced. Therefore, the HMD can be worn by the user for a longer period of time.

[0014] In at least one example, the HMD may include a first display module, which may include a first lens, a first housing surrounding the first lens and defining a first internal volume, and a first display screen disposed within the first internal volume, the first display screen being able to project light through the first lens. The HMD may also include a second display module, which may include a second lens, a second housing surrounding the second lens and defining a second internal volume isolated from the first internal volume by the first and second housings, and a second display screen disposed within the second internal volume, the second display screen being able to project light through the second lens. In this way, the HMD may include two separate housings having separate lenses and display screens.

[0015] In at least one example, the HMD may include a first fixed arm extending from a first housing and a second fixed arm extending from a second housing. The HMD may include a data transmission cable electrically coupled to a first display and extending through the first fixed arm, and an electrical port electrically coupled to the first and second displays via the data transmission cable. The electrical port may be connected to an external computing unit that can control the visual output of the first and second displays. In at least one example, the HMD may also include a power cable extending through the second fixed arm and electrically coupled to the second and first displays. In at least one example, the external computing unit may include a processor, battery, cooling fan, etc. In this way, the HMD does not include a cooling fan or computing unit. This can significantly reduce the weight of the HMD, increasing comfort during extended use without sacrificing any performance.

[0016] The following text is for reference only. Figures 1 to 5 These and other embodiments are discussed. However, those skilled in the art will readily understand that the detailed descriptions given herein with respect to the accompanying drawings are for illustrative purposes only and should not be construed as limiting. Furthermore, as used herein, a system, method, article of manufacture, component, feature, or sub-feature including at least one of the first, second, or third options should be understood to refer to a system, method, article of manufacture, component, feature, or sub-feature that may include one option of each listed option (e.g., only one first option, only one second option, only one third option), multiple options of a single listed option (e.g., two or more first options), two options simultaneously (e.g., one first option and one second option), or combinations thereof (e.g., two first options and one second option).

[0017] Figure 1 An isometric view of a head-mounted device 100 (HMD 100) is illustrated. HMD 100 can be any device or system that can be worn on a user's head, such as head-mounted electronic devices, optical devices, smart glasses, mixed reality goggles, etc. Figure 1As shown, HMD 100 may include a first display assembly 102 and a second display assembly 104. In at least one example, when HMD 100 is worn, the first display assembly 102 and the second display assembly 104 may be positioned in front of the user's eyes. For example, the first display assembly 102 may be in front of the right eye, and the second display assembly 104 may be in front of the left eye, or vice versa. The first display assembly 102 may include a first display (not illustrated) and a first housing 106 surrounding the first display. In this way, the first display is positioned in front of the user's eyes. The second display assembly 104 may include a second display and a second housing 108 surrounding the second display, wherein the second display is positioned in front of the user's eyes. In this way, HMD 100 defines two separate housings having independent display assemblies.

[0018] In at least one example, the HMD 100 may include a first fixing arm 110 extending from a first housing 106 and a second fixing arm 112 extending from a second housing 108. In at least one example, the first fixing arm 110 and the second fixing arm 112 may rest on the user's ear to distribute the weight of the HMD 100. In at least one example, the first fixing arm 110 and the second fixing arm 112 may also include curved portions at their distal ends to secure behind the user's ear, thereby increasing the stability of the HMD 100 during all types of activity. In at least one example, the HMD 100 may include a strip, strap, or the like instead of fixing arms.

[0019] In at least one example, the HMD 100 may include a data transmission cable electrically coupled to the first display and extending through the first fixed arm 110 (e.g., Figure 2A (As illustrated). In at least one example, the HMD 100 may also include an electrical port 114, which can be electrically coupled to a first display and a second display via a data transmission cable. The electrical port can be connected to an external computing unit that can control the visual output of the first and second displays. Although the electrical port 114 is... Figure 1The display is illustrated as being located on the second fixed arm 112, but it should be understood that it can be located on the first fixed arm 110 or on both the first fixed arm 110 and the second fixed arm 112. Furthermore, it should be understood that the electrical port 114 can be located at any position along the first fixed arm 110 and the second fixed arm 112, and can be located at the distal ends of the first fixed arm 110 and the second fixed arm 112. The external computing unit may include a processor that can transmit all control signals received by the first and second displays via data transmission cables. In at least one example, the external computing unit may also include memory, storage devices, power supplies, etc. In this way, the HMD 100 does not house computing components, and neither the first display assembly 102 nor the second display assembly 104 includes a cooling fan. The following text refers to... Figure 4A and Figure 4B Discussed in more detail, the first display assembly 102 and the second display assembly 104 may include cooling vents to cool the electronic components housed within them. Without computing components, the weight of the HMD 100 can be significantly reduced, increasing comfort and allowing users to wear the HMD 100 for longer periods.

[0020] like Figure 1 As illustrated, HMD 100 may further include a first cover 116 coupled to a first housing 106 opposite to a first display screen and a second cover 118, separate from the first cover 116, coupled to a second housing 108 opposite to a second display screen. In at least one example, the first cover 116 and the second cover 118 may be opaque. In this way, HMD 100 can be used for VR because the user cannot see through the first display assembly 102 and the second display assembly 104. Furthermore, the first cover 116 and the second cover 118 prevent light from the first and second displays from leaking from the front of the first display assembly 102 and the second display assembly 104. In at least one example, HMD 100 may also include an eyecup or occluder (not illustrated) that can be fixed to the first housing 106 and the second housing 108. In this example, the eyecup can be fixed to the user's eye socket to achieve full levitation with HMD 100. This can further reduce light leakage from the display to the user's eyes, which can increase immersion. Furthermore, the eye cup can distribute the load onto the eye socket, which will further distribute the weight of the HMD 100 for more comfortable use. In at least one example, the HMD 100 may include a shield coupled to the first fixation arm 110 and the second fixation arm 112, which can block light from the user's environment when the user wears the HMD 100.

[0021] Figure 1Any of the features, components, and / or parts of the illustrated electronic device (including their arrangement and configuration) may be included, individually or in any combination, in any of the other examples of devices, features, components, and parts shown in the other figures. Similarly, any of the features, components, and / or parts shown in the other figures (including their arrangement and configuration) may be included, individually or in any combination. Figure 1 Examples of devices, features, components, and parts are shown.

[0022] Figures 2A to 2B Various views of the HMD 100 are shown. Figure 2A Examples Figure 1 A top view of the HMD 100. Figure 2B Examples Figure 1 The image shows a front view of the HMD 100. The HMD 100 may include a first display assembly 102 and a second display assembly 104. The first display assembly 102 may include a first lens 220, a first housing 106 surrounding the first lens 220 and defining a first internal volume 224, and a first display screen 228 disposed within the first internal volume 224, the first display screen being able to project light through the first lens 220. Figure 2A As illustrated, the first lens 220 can be positioned in front of the user's eyes such that when light projected from the first display screen 228 passes through the first lens 220, the light is directed to the user's eyes. Figure 2A and Figure 2B As illustrated, the first housing 106 may define a first outer surface 244. The second display assembly 104 may include a second lens 222, a second housing 108 surrounding the second lens 222 and defining a second internal volume 226 isolated from the first internal volume 224 by the first housing 106 and the second housing 108, and a second display screen 230 disposed in the second internal volume 226, the second display screen being able to project light through the second lens 222. Figure 2A and Figure 2B As illustrated, the second housing 108 may define a second outer surface 246 that is separate from and isolated from the first outer surface 244. In this way, the first display assembly 102 and the second display assembly 104 can both operate independently of each other as separate display assemblies.

[0023] In at least one example, the HMD 100 may also include a bridging member 232 extending between the first housing and the second housing to separate and couple the first housing 106 and the second housing 108. Figure 2A and Figure 2BAs illustrated, the bridging member 232 can separate the first housing 106 and the second housing 108 from each other. When a user wears the HMD 100, the bridging member 232 can rest on the user's nose bridge to secure the HMD 100 to the user's face, aligning the first display 228 with the user's eyes and the second display 230 with the user's other eye. In conventional HMDs, the user's nose bridge can bear most of the HMD's weight, and fatigue may occur on the user's nose, which can make wearing the HMD for extended periods difficult and uncomfortable. In this disclosure, the HMD 100 is lighter to increase the comfort of wearing the HMD 100.

[0024] In at least one example, the HMD 100 may include a first retaining arm 110 extending from a first housing 106 and a second retaining arm 112 extending from a second housing 108. In at least one example, the first retaining arm 110 and the second retaining arm 112 may rest on the user's ear to distribute the weight of the HMD 100. The first retaining arm 110 and the second retaining arm 112 may remove the weight of the HMD 100 from the user's bridge of the nose to increase comfort when wearing the HMD 100. Figure 2A As illustrated, the first fixing arm 110 and the second fixing arm 112 may be defined and coupled to the proximal end 234 and the distal end 236 of the first housing 106 and the second housing 108.

[0025] In at least one example, the HMD 100 may also include a data transmission cable 238 electrically coupled to the first display screen 228 and extending through the first fixed arm 110. The data transmission cable 238 can transmit data to the first display assembly 102 and the second display assembly 104. The HMD 100 also includes an electrical port 114 electrically coupled to the first display screen 228 and the second display screen 230 via the data transmission cable 238. The data transmission cable 238 can extend uninterruptedly between the electrical port 114 and the first display screen 228 without being electrically coupled to any intermediate processing components between the electrical port and the first display screen 228. Figure 2A As illustrated, the data transmission cable 238 may extend from the electrical port 114 of the second fixed arm 112, through the second display assembly 104, through the bridge 232, through the first display assembly 102, and through the first fixed arm 110.

[0026] In at least one example, the HMD 100 may further include a power cable 240 extending through the second mounting arm 112 and electrically coupled to the second display 230 and the first display 228. In this example, the power cable 240 can transfer power from an external power source to the first display assembly 102 and the second display assembly 104. In this example, the HMD 100 may include a data transmission cable 238 extending through the first mounting arm 110 and electrically coupled to the first display 228 and the second display 230, and a power cable 240 extending through the second mounting arm 112 and electrically coupled to the first display 228 and the second display 230. The power cable 240 is electrically coupled to an electrical port 114. Figure 2A As illustrated, electrical port 114 may be defined in the distal end 236 of the second retaining arm 112. In at least one example, the first retaining arm 110 may define a data port 242 located in the distal end 236 of the first retaining arm 110, such as Figure 2A As illustrated, the data transmission cable 238 can be electrically coupled to the data port 242. It should be understood that the electrical port 114 can be located in the first fixed arm 110 or the second fixed arm 112, or in a belt, etc., and the data port 242 can be located in the first fixed arm 110 or the second fixed arm 112, or in a belt, etc.

[0027] In at least one example, the HMD 100 may include a single port in either the first mounting arm 110 or the second mounting arm 112, which can transmit power and data to the first display assembly 102 and the second display assembly 104. For example, a power / data cable may extend through the first mounting arm 110 to transmit power and data to the first display screen 228, and through the bridging member 232 to transmit power and data to the second display screen 230. In this way, an external computing unit can be electrically coupled to a single port on the HMD 100. This increases ease of manufacture and user comfort when wearing the HMD 100.

[0028] In these examples, the HMD 100 does not contain a computing unit, and an external computing unit can be electrically coupled to the HMD 100. The external computing unit may include a processor, memory, storage unit, battery, etc. The external computing unit can be electrically coupled to the HMD 100 via electrical port 114 and data port 242. In this example, the external computing unit may be a small device (e.g., disc-shaped, square-shaped, etc.) that can be placed in a user's pocket when wearing the HMD 100. The external computing unit may include a wire extending from and coupled to electrical port 114 to provide power to the first fixed arm 110 and a wire coupled to data port 242 to provide data to the HMD 100. In one example, the HMD 100 may include a single power / data port, and a wire extending from the external computing unit may be electrically coupled to the power / data port to transmit both data and power. In this way, the HMD 100 does not contain a heavy computing unit and a cooling fan for the computing unit. Therefore, the HMD 100 can be lighter than a conventional HMD and can be worn by a user for extended periods.

[0029] Figure 2A and Figure 2B Any of the features, components, and / or parts of the illustrated electronic device (including their arrangement and configuration) may be included, individually or in any combination, in any of the other examples of devices, features, components, and parts shown in the other figures. Similarly, any of the features, components, and / or parts shown in the other figures (including their arrangement and configuration) may be included, individually or in any combination. Figure 2A and Figure 2B Examples of devices, features, components, and parts are shown.

[0030] Figures 3A to 3B Examples Figure 1 Various views of a portion of the HMD 100. Figure 3A The front isometric view of this part of the HMD 100 is shown as an example. Figure 3B This example shows a rear isometric view of this section of the HMD 100. (See example...) Figure 3A and Figure 3B As illustrated, the HMD 100 may include a first display assembly 102, which may include a first housing 106, a first lens 220, and a first cover 116, the first cover being coupled to the first housing 106 opposite to the first lens 220. The first display assembly 102 may also include a first display (not illustrated) disposed between the first lens 220 and the first cover 116. Figure 3A and Figure 3B As illustrated, the HMD100 may also include a first retaining arm 110 extending from the first housing 106.

[0031] like Figure 3AAs illustrated, the first cover 116 may cover a large portion of the front surface 348 of the first display assembly 102. In at least one example, the first cover 116 may be opaque to block light from entering through the front surface 348 of the first display assembly 102. In this way, the first display assembly 102 and the first display screen can provide the user with the most immersive experience without light entering the device. In at least one example, the first housing 106 may surround the first cover 116, such as... Figure 3A As illustrated. In at least one example, the first housing 106 110 may define a solid front surface 348 excluding the first cover 116. In this way, light can still be blocked from entering through the first housing 106. In this way, the first cover 116 and the first housing 106 may define a smooth and aesthetically pleasing appearance.

[0032] like Figure 3B As illustrated, the first lens 220 may cover a large portion of the rear surface 350 of the first display assembly 102. A first housing 106 may surround the first lens 220. The first lens 220 may be positioned within the first display assembly 102 such that it is aligned with the user's eyes when the user wears the HMD 100. Figure 3B As illustrated, the first lens 220 can be a square lens. In at least one example, the first lens 220 can be a square lens, a circular lens, an octagonal lens, etc.

[0033] As discussed above, the first fixing arm 110 may include an eye cup (not shown) that is coupled to the rear surface 350. In this example, the eye cup may be shaped according to the shape of the first lens 220. When a user wears the HMD 100, the eye cup can be fixed to the user's eye socket to distribute the weight of the HMD 100 and hold the HMD 100 to the user's face. For example, a user may wear the HMD 100 during exercise, and the eye cup can hold the HMD 100 to the user's face during movement. Furthermore, the eye cup can block external light interference from the display screen that passes through the first lens 220 and is directed to the user's eyes. In this way, the HMD 100 with the eye cup can provide a more immersive experience.

[0034] Figure 3A and Figure 3B Any of the features, components, and / or parts of the illustrated electronic device (including their arrangement and configuration) may be included, individually or in any combination, in any of the other examples of devices, features, components, and parts shown in the other figures. Similarly, any of the features, components, and / or parts shown in the other figures (including their arrangement and configuration) may be included, individually or in any combination. Figure 3A and Figure 3B Examples of devices, features, components, and parts are shown.

[0035] Figure 4A and Figure 4B Examples Figure 1 Various views of the HMD 100. Figure 4A An exploded view of the HMD 100 is shown. Figure 4B Examples are given by Figure 2B The image shows a cross-sectional view of the HMD 100 taken by cutting line AA. In at least one example, the HMD 100 may include a first display assembly 102, which may include a first display screen 228, a first housing 106 surrounding the first display screen 228, a first lens 220 coupled to the first housing 106, and a first cover 116 coupled to the first housing 106 opposite to the first lens 220. Figure 4A and Figure 4B As illustrated, a first housing 106 may be disposed between the first lens 220 and the first cover 116. Although not illustrated, it should be understood that the HMD 100 may include a second display screen 230, a second housing 108 surrounding the second display screen, a second lens coupled to the second housing, and a second cover coupled to the second housing opposite to the second lens. Therefore, the second housing may be disposed between the second lens and the second cover. In this way, the HMD 100 may define two distinct housings that are separate from each other.

[0036] like Figure 4A and Figure 4B As illustrated, a first display screen 228 may be disposed between the first lens 220 and the first cover 116. In at least one example, the first display screen 228 may block light from passing between the first lens 220 and the first cover 116. The first display screen 228 is positioned to direct light supplied by the first display screen 228 through the first lens 220 to the user's eyes without allowing light to leak into the front of the first display assembly 102, which could otherwise reduce immersion and the quality of the displayed image. In this example, a second display screen may block light from passing between the second lens and the second cover.

[0037] In at least one example, the first lens 220 may be surrounded by a first housing 106. For example... Figure 4A As illustrated, the first lens 220 may be disposed within the first housing 106 to form a flush interface. In another example, such as Figure 4B As illustrated, the first lens 220 may be positioned on the first housing 106. In this example, the first lens 220 covers the rear surface 350 of the first housing 106.

[0038] In at least one example, the first cover 116 may cover the front surface 348 to block light from entering the first display assembly 102. In another example, the first cover 116 may be positioned within the first housing 106 to form a flush interface. In at least one example, the first cover 116 may be opaque to block light from entering the HMD 100. In this way, when the HMD 100 is worn, the user cannot look out through the HMD 100. The user will be immersed solely in the content displayed on the screen.

[0039] In at least one example, HMD 100 may include an external computing unit. In a conventional HMD, the computing unit may be housed within the HMD, which can significantly increase the weight of the HMD. In this way, the computing unit generates heat during operation, and a conventional HMD must include a cooling fan to cool the computing unit during operation. In this disclosure, HMD 100 does not include computing components, and the first display assembly 102 and the second display assembly do not include cooling fans. In at least one example, HMD 100 may include a printed circuit board (PCB) 452 disposed within a first housing 106. PCB 452 may include multiple resistors, capacitors, diodes, sensors, transistors, integrated circuits, etc. PCB 452 may be electrically coupled to a first display screen 228 to control the first display screen 228 during operation of HMD 100.

[0040] In at least one example, the first housing 106 may include at least one vent 454. For example... Figure 4A and Figure 4B As illustrated, the first housing 106 may include vents 454 on the top and bottom. In at least one example, the first housing 106 may include one vent 454, two vents 454, three vents 454, four vents 454, etc. The vents 454 can allow cool air to enter the HMD 100 to cool limited computing components (e.g., PCB 452, first display 228, etc.). In this way, the HMD 100 can passively cool the components without using energy-consuming cooling fans that may add weight. Therefore, the HMD 100 of this disclosure can significantly reduce weight to increase comfort for extended use.

[0041] In at least one example, HMD 100 may further include a bridging member 232 that can connect the first display assembly 102 and the second display assembly. As discussed above, bridging member 232 can separate the first display assembly 102 and the second display assembly to form and can be positioned on the bridge of the user's nose when the HMD 100 is worn. In at least one example, bridging member 232 can electrically couple the first display assembly 102 and the second display assembly. In this example, HMD 100 may include power cables, data cables, and / or power / data cables that can electrically couple the first display assembly 102 and the second display assembly via bridging member 232.

[0042] Figures 4A to 4B Any of the features, components, and / or parts of the illustrated electronic device (including their arrangement and configuration) may be included, individually or in any combination, in any of the other examples of devices, features, components, and parts shown in the other figures. Similarly, any of the features, components, and / or parts shown in the other figures (including their arrangement and configuration) may be included, individually or in any combination. Figure 4A and Figure 4B Examples of devices, features, components, and parts are shown.

[0043] Figure 5 A side view of HMD 100 is illustrated. In at least one example, HMD 100 may include: a first display assembly 102, which may include a first housing 106; and a first fixing arm 110 extending from the first housing 106. Although not illustrated, HMD 100 may include: a second display assembly, which may include a second housing; and a second fixing arm extending from the second housing. In one example, HMD 100 may include a strap or band that secures the first display assembly 102 and the second display assembly to the user's face and positions them in front of the user's eyes. The fixing arm secures HMD 100 to the user's face when the user engages in various activities (e.g., office work, walking, exercising, etc.).

[0044] In at least one example, HMD 100 may include an electrical port 114, which may be disposed in a first fixing arm 110, a second fixing arm, a belt, a strip, a first housing 106, etc. HMD 100 may not contain a computing component and may include an external computing unit 556. External computing unit 556 may include a processor that transmits all control signals to HMD 100. In at least one example, external computing unit 556 may include a battery that transmits power to HMD 100. In at least one example, external computing unit 556 may also include a cooling fan, memory, storage device, etc.

[0045] The HMD 100 may also include an external computing unit power cable 558 that electrically couples the electrical port 114 to the external computing unit 556. In at least one example, the external computing unit power cable 558 may extend from the electrical port 114, allowing the user to place the external computing unit 556 in a pocket while wearing the HMD 100. In at least one example, the external computing unit power cable 558 may vary based on the desired activity. For example, in an office environment, a shorter cable may be desired to rest the external computing unit 556 on a desk while the user is working. In another example, in an exercise environment, a longer cable may be desired to position the external computing unit 556 in a pocket. In yet another example, the external computing unit 556 may be attached to a fixed arm or strap or band. In this example, a shorter external computing unit power cable 558 may be desired.

[0046] Although illustrated as a single cable, the external computing unit power cable 558 can be two cables (e.g., a power cable and a data transmission cable). In this example, the power cable can be electrically coupled to a data port (such as electrical port 114), and the data transmission cable can be electrically coupled to a data port (such as...). Figure 2A (Data port 242 is illustrated). In another example, the external computing unit power cable 558 may be a single conductor extending from the external computing unit 556, which may be divided into a power cable and a data transmission cable.

Similarly, any of the features, components, and / or parts shown in the other figures (including their arrangement and configuration) may be included, individually or in any combination. Figure 5 Examples of devices, features, components, and parts are shown.

[0048] Within the limits applicable to the techniques of this invention, the collection and use of data available from various sources can be used to improve the delivery of inspirational content or any other content that a user may be interested in. This 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 specific individuals. Such personal information data may include demographic data, location-based data, telephone numbers, email addresses, Twitter accounts, etc. ®ID, home address, data or records related to the user's health or health level (e.g., vital sign measurements, medication information, exercise information), date of birth, or any other identifying or personal information.

[0049] This disclosure recognizes that the use of such personal information data in the techniques of this invention can benefit users. For example, the personal information data can be used to deliver targeted content that is of interest to the user. Therefore, the use of such personal information data enables users to have planned control over the delivered content. Furthermore, this disclosure also anticipates other uses of personal information data that are beneficial to users. For example, health and fitness data can be used to provide insights into a user's overall health status or as positive feedback for individuals using technology to pursue health goals.

[0050] This disclosure anticipates that entities responsible for the collection, analysis, disclosure, transmission, storage, or other use of such personal information data will comply with robust privacy policies and / or privacy practices. Specifically, such entities should implement and adhere to privacy policies and measures recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy and security of personal information data. These policies should be readily accessible to users and should be updated as data collection and / or use change. Personal information from users should be collected for legitimate and reasonable entity purposes and should not be shared or sold outside of these legitimate purposes. Furthermore, such collection / sharing should be conducted only after receiving informed consent from users. Additionally, such entities should consider taking any necessary steps to protect and safeguard the right to access such personal information data and ensure that other entities with access to such personal information data comply with their privacy policies and procedures. Furthermore, such entities may be subject to third-party assessments to demonstrate their compliance with widely accepted privacy policies and practices. Moreover, policies and measures should be adapted to the specific types of personal information data collected and / or accessed, and to applicable laws and standards, including considerations of specific 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 in other countries, health data 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.

[0051] Regardless of the foregoing, this disclosure also anticipates implementation schemes that allow users to selectively block the use or access to personal information data. That is, this disclosure anticipates providing hardware and / or software components to prevent or block access to such personal information data. For example, in the case of advertising delivery services, the technology of this invention may allow users to opt-in or opt-out at any time during or after registration for the service to participate in the collection of personal information data. In another example, users may choose not to provide emotion-related data for a targeted content delivery service. In yet another example, users may choose to limit the duration for which emotion-related data is retained, or to completely prohibit the development of basic emotional states. In addition to providing "opt-in" and "opt-out" options, this disclosure also anticipates providing notifications related to access to or use of personal information. For example, users may be notified when downloading an application that their personal information data will be accessed, and then reminded again just before the application accesses the personal information data.

[0052] Furthermore, the intent of this disclosure is that personal information data should be managed and processed in a manner that minimizes the risk of unintentional or unauthorized access or use. Once data is no longer needed, this risk can be minimized by restricting data collection and deleting data. Additionally, and where applicable, including in certain health-related applications, data deidentification can be used to protect user privacy. Deidentification can be facilitated, where appropriate, 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 the address level), controlling how data is stored (e.g., aggregating data among users), and / or other methods.

[0053] Therefore, while this disclosure broadly covers the use of personal information data to implement one or more of the various disclosed embodiments, it is also contemplated that various embodiments can be implemented without access to such personal information data. That is, various embodiments of the present invention will not become inoperable due to the absence of all or part of such personal information data. For example, preferences can be inferred based on non-personal information data or a minimal amount of personal information such as content requested by a device associated with a user, other non-personal information available to the content delivery service, or publicly available information, thereby selecting content and delivering it to the user.
