Various components of these devices, such as displays, visors, headbands, speakers, batteries, and other components, work together to provide an immersive and comfortable experience. For various reasons, users of wearable devices may prefer to set the displays of these devices at different distances from their eyes. Therefore, wearable devices including displays that can be adjusted relative to the user's eyes are desirable. SUMMARY OF THE INVENTION

[0025] Reference will now be made in detail to 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. Instead, it is intended to cover alternatives, modifications, and equivalents that may be included in the spirit and scope of the described embodiments as defined by the appended claims.

[0026] The following disclosure relates to wearable electronic devices (e.g., head-mounted devices (HMDs)). More specifically, the present example relates to an HMD including a display whose position is adjustable relative to a user's eyes.

[0027] In some examples, a wearable device may include a display unit and a fixed strap extending from the display unit. The wearable device may be secured to a user's head by the fixed strap such that a display of the display unit is positioned in front of the user's eyes. Depending on user preferences, activities performed while wearing the wearable device, the position of the user's body, the user's surrounding environment, etc., the user may prefer to set the display at different distances from their eyes.

[0028] The wearable device of the present disclosure includes a display that is adjustable relative to the eyes of a user of the wearable device. More specifically, the display is adjustable such that the distance between the user's eyes and the display is adjustable. As will be discussed in detail below, the wearable device may include an actuator that can be used to adjust the position of the display relative to the user's eyes. The actuator may include an automatic actuator (e.g., a motor, etc.), a manual actuator (e.g., a dial, a button, a slidable actuator, a spring-loaded actuator, a telescoping actuator, a linkage, a combination thereof, etc.), a combination thereof, etc. The wearable device may include one actuator and be limited to adjusting the distance between the display and the user's eyes, or may include multiple actuators and further adjust the angle of the display relative to the user's eyes. Providing an actuator for the wearable device to adjust the position of the display relative to the user's eyes can improve user comfort, allow a single wearable device to be used by users with different facial features, allow the wearable device to better fit user preferences, allow different positions of the display for different activities and different body positions of the user, maintain a comfortable relative distance between the user and the display while wearing the wearable device, etc.

[0029] These and other embodiments are discussed below with reference to Figures 1A through 4C However, those skilled in the art will readily understand that the detailed descriptions given herein with respect to these figures are for illustrative purposes only and should not be construed as limiting. Additionally, as used herein, a system, method, article of manufacture, component, feature, or sub-feature that includes at least one of a first option, a second option, or a third option should be understood to refer to a system, method, article of manufacture, component, feature, or sub-feature that may include one (e.g., only one first option, only one second option, only one third option) of each of the listed options, multiple 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 a combination thereof (e.g., two first options and one second option).

[0030] Figure 1A and Figure 1BTop and side views of a head - mountable device (HMD) 100 worn on a user's head 101 are respectively illustrated. The HMD 100 may include a display 102, a face interface 106, a first frame 110, a second frame 114, a strip 116, a strap 118, a cover 120, and a device seal 122. As will be discussed in detail below, the second frame 114 may be coupled to the first frame 110 by an actuator 112 that allows adjustment of the relative position of the second frame 114 with respect to the first frame 110. This configuration also allows adjustment of the relative position of the display 102 with respect to the user's eyes. Although the particular device 100 may be referred to as an HMD, it should be understood that the terms wearable device, wearable electronic device, HMD device, and / or HMD system may be used to refer to any wearable device, including smart glasses.

[0031] The display 102 may include one or more optical lenses or displays configured to be positioned in front of the user's eyes. The display 102 may include a display 104 configured to present an augmented reality visualization, a virtual reality visualization, or other suitable visualization to the user. The display 104 may be at least partially positioned within or on the second frame 114. The second frame 114 may be the housing of the display 102. In some examples, the device seal 122 includes the second frame 114 (e.g., the second frame 114 may be part of the device seal 122). The second frame 114, the display 102, and the device seal 122 may together form a display housing.

[0032] The device seal 122 may include the face interface 106, the cover 120, the first frame 110, and electrical components. The device seal 122 may also be referred to as a light seal or a face interface configured to seal the user's eyes from ambient light. In some examples, the device seal 122 may refer to the portion of the HMD 100 that engages or shields a part of the user's face. The device seal 122 may include portions of the HMD 100 that conform to, contact, or abut the regions of the user's face (e.g., the face interface 106). The face interface 106 may conform to the regions of the user's face (e.g., press against and take the shape of these regions). In some examples, the face interface 106 may include a flexible (or semi - flexible) material that spans the forehead region, partially wraps around the eyes, and contacts the zygomatic and / or maxillary regions of the user's face.

[0033] The cover 120 may include a seal, a facial interface, an environmental seal, a dust seal, an air seal, etc. positioned between the display 102 and the user's face. The cover 120 may be a non-rigid or deformable woven fabric. The cover 120 may be elastically deformable. In some examples, the cover 120 may be a plastic, rubber, or polymeric material. In some examples, the cover 120 may be rigid. In some examples, the cover 120 may expand and contract, such as when the distance between the first frame 110 and the second frame 114 is adjusted. The cover 120 may be formed of an elastic material, an accordion-shaped material, a stretchable material, etc. The cover 120 may form an eye box through which the user may view the display 102. It should be understood that, in addition to a complete seal, the term "seal" may also include a partial seal or a suppressant (e.g., a partial light seal that blocks some ambient light or a complete light seal that blocks all ambient light when the HMD 100 is worn).

[0034] The first frame 110 may be coupled to the facial interface 106 via a connector 108. In some examples, the connector 108 allows the facial interface 106 to translate and / or rotate relative to the first frame 110. The connector 108 may movably constrain the facial interface 106 to the first frame 110. In other words, the connector 108 may provide controlled movement between the facial interface 106 and the first frame 110, which may be used to ensure that the facial interface 106 conforms to or otherwise adapts to the facial features of the user's head 101. In some examples, the connector 108 may be provided adjacent to the facial features of the user's head (such as the forehead region, the cheekbone region, and / or the maxilla region). However, the connector 108 may be provided in any desired orientation. The connector 108 may include one or more joints (e.g., pivot joints, soft joints, flex joints, spring joints, etc.) that allow (or actively provide) the translation and / or rotation of the facial interface 106 relative to the first frame 110.

[0035] The strap 116 and / or the band 118 may hold the HMD 100 relative to the user's head 101. The strap 116 may be connected to the device seal 122 and may extend distally towards the rear of the user's head 101. In some examples, the strap 116 may be an extension of the display housing, such as the device seal 122. The strap 116 may be coupled to the left and right sides of the device seal 122 to physically and / or electrically couple the strap 116 to the device seal 122. The strap 116 may be further physically and / or electrically coupled to the display 102 directly or through the device seal 122. The strap 116 is configured to hold the display 102 in a fixed position relative to the user's head 101 (e.g., such that the display 102 remains in front of the user's eyes). For example, the strap 116 may extend above the user's ears. In some examples, the strap 116 may rest on the user's ears to secure the HMD 100 via friction between the strap 116 and the user's head 101. For example, the strap 116 may apply opposing pressure to the sides of the user's head 101 to secure the HMD 100 to the user's head 101. Optionally, the straps 116 may be connected to each other via the band 118, which may press the HMD 100 against the user's head 101. The strap 116 may include sensors, buttons, speakers, and / or other electrical components. Hinges and / or other mechanisms may be used to couple the strap 116 to the device seal 122. In some examples, the strap 116 may be integrally formed as parts of the device seal 122.

[0036] The second frame 114 may be coupled to the first frame 110 by an actuator 112. The actuator 112 may be provided to allow adjustment of the relative position of the first frame 110 and the second frame 114. This may be used to control the relative position of the display 104 and the user's eyes. The actuator 112 may provide control over the distance D 1 (e.g., varying the distance between the user's eyes and the display 104), the pitch angle between the first frame 110 and the second frame 114 (e.g., the angle in the pitch axis 130 parallel to the longitudinal axis of the display 102), the yaw angle between the first frame 110 and the second frame 114 (e.g., the angle in the yaw axis 132 perpendicular to the longitudinal axis of the display 102 and the longitudinal axis of the strap 116), or any other desired variable in the relative position of the first frame 110 and the second frame 114. In some examples, the distance D 1The range can be from about 5 mm to about 45 mm, from about 5 mm to about 38 mm, from about 15 mm to about 36 mm, etc. The actuator 112 can provide a stroke of about 5 mm, about 10 mm, about 15 mm, about 20 mm, up to about 40 mm, etc. The actuator 112 can be coupled to the first frame 110 and / or the second frame 114 through a ball joint or other joint that allows the actuator 112 to pivot relative to the first frame 110 and / or the second frame 114, which allows adjustment of the pitch angle, yaw angle, and other relative angles between the first frame 110 and the second frame 114. Providing the actuator 112 to adjust the relative position of the first frame 110 and the second frame 114 can improve user comfort, increase or otherwise improve the user's field of view of the display 104, accommodate users with different facial features and personal preferences, provide a more immersive experience to the user when wearing the HMD 100, etc.

[0037] In some examples, the actuator 112 can be positioned between the first frame 110 and the second frame 114 at a position aligned with a feature on the user's face, such as aligned with the user's forehead and the user's cheekbone and / or maxilla area. In some examples, the HMD 100 can include four actuators 112, two actuators 112 positioned to be aligned with the user's forehead, and two of the actuators 112 aligned with the user's cheekbone and / or maxilla area. The HMD 100 can include more or fewer actuators 112, and the actuators can be positioned at any desired position between the first frame 110 and the second frame 114. Providing a greater number of actuators 112 can provide control over a greater number of variables (e.g., axial relationships) in the relative position of the first frame 110 and the second frame 114. For example, a single actuator 112 can be provided to allow adjustment of the distance between the first frame 110 and the second frame 114. Two actuators 112 can be provided to allow adjustment of the distance between the first frame 110 and the second frame 114, and the angle between the first frame 110 and the second frame 114 along a first axis. Three actuators 112 can be provided to allow adjustment of the distance between the first frame 110 and the second frame 114, and the angles between the first frame 110 and the second frame 114 along a first axis and a second axis. Any number of actuators 112 can be provided, depending on the number of variables in the relative position of the first frame 110 and the second frame 114 that are desired to be controlled.

[0038] Any suitable actuator can be used for actuator 112. Actuator 112 can be actuated manually or automatically, such as in response to a signal from a processor or other electronic device. In an example where actuator 112 is actuated automatically, actuator 112 can include a motor controlled by HMD 100. The motor can include a piezoelectric motor, an LVDT electromagnetic actuator, a micro hydraulic actuator, a brushed or brushless DC motor, a stepper motor, any other suitable motor, etc. In an example where actuator 112 is actuated manually, HMD 100 can provide a prompt to the user to adjust actuator 112. Manually actuating actuator 112 can include a dial, a button, a slidable actuator, a ratchet strap, a spring-loaded actuator, a telescoping actuator, etc. Actuator 112 can be used in combination with a linkage or can include a linkage, such as a scissor linkage, a Hoecken linkage, a rack and pinion linkage, a pulley, a lead screw, etc. The linkage can convert the rotational movement of actuator 112 into a translational movement of the second frame 114 relative to the first frame 110, or can convert other movement of actuator 112 into a desired movement of the second frame 114 relative to the first frame 110. In Figure 1A and Figure 1B the example illustrated in, actuator 112 is disposed perpendicular to the longitudinal axes of the display 102 and the strip 116; however, actuator 112 can be disposed at any desired angle relative to the display 102 and the strip 116, and a linkage can be used to produce a desired movement of the second frame 114 relative to the first frame 110 regardless of the position of actuator 112.

[0039] Actuator 112 can be non-backdrivable. For example, actuator 112 can include a non-backdrivable motor or a detent. The detent can include a button, a hole and a pin, a fastener, a ratchet and pawl, a combination thereof, etc. Actuator 112 can be non-backdrivable in one direction or in multiple directions. Providing a non-backdrivable actuator 112 prevents the second frame 114 from moving relative to the first frame 110 from a certain position unless actuator 112 is actuated. In an example where actuator 112 includes a detent, the detent can be disengaged (such as by pressing a button), actuator 112 can be used to move the second frame 114 relative to the first frame 110, and the detent can be engaged (such as by releasing the button). This prevents the display 102 from collapsing towards the user's face when the display 102 contacts an external object. This also prevents unwanted movement of the display 102 relative to the user's eyes when using HMD 100.

[0040] In some examples, the HMD 100 may be used while a user performs activities of various activity types. These activity types may include dynamic activities, static activities, activities of different degrees of immersion, etc. The actuator 112 may adjust the relative position of the second frame 114 and the first frame 110 based on the activity type for which the HMD 100 is used. For example, the distance between the second frame 114 and the first frame 110 may be increased by the actuator 112 for dynamic activities, where the increased relative distance is desired and optical quality is less important. The distance between the second frame 114 and the first frame 110 may be decreased by the actuator 112 for static activities and immersive activities, where optical quality and field of view are more important. Thus, the actuator 112 may be included to improve optical quality, comfort, corresponding positioning, and field of view in the HMD 100.

[0041] In some examples, the HMD 100 may include one or more sensors, and the actuator 112 may be used to adjust the relative position of the first frame 110 and the second frame 114 (e.g., the relative position of the user's eyes and the display 102) based on signals generated by the sensors. For example, the HMD 100 may include an inward-facing optical sensor that detects and tracks the gaze of the user of the HMD 100. The actuator 112 may move the second frame 114 relative to the first frame 110 corresponding to the direction of the user's gaze. In some examples, an application accessed by the HMD 100 may use the actuator 112 to move the second frame 114 relative to the first frame 110 to prompt the user to gaze in a desired direction. In some examples, the HMD 100 may include an inward-facing optical detector that detects and analyzes the facial features of the user of the HMD 100, etc. These facial features may be used by the HMD 100 to determine the optimal viewing distance of the user, and the actuator 112 may move the second frame 114 relative to the first frame 110 to provide the user with the optimal viewing distance. In some examples, the HMD 100 may include an outward-facing optical detector, an inertial measurement unit, etc., which may detect the environment around the user, as well as the user's interaction with their environment or movement through their environment. This environmental data may be used with the actuator 112 to move the second frame 114 relative to the first frame 110 to provide the user with a warning or other indication about their proximity to obstacles in their environment. In some examples, the environmental data may be used with the actuator 112 to move the second frame 114 relative to the first frame 110 to prompt the user to move in a desired direction, such as moving away from a boundary in the user's environment. In some examples, the environmental data may be used to detect or anticipate undesirable environmental conditions. In the case of detecting or anticipating undesirable or uncomfortable environmental conditions, the actuator 112 may move the second frame 114 away from the first frame 110 to maintain a comfortable relative positioning of the user's face and the display 102.

[0042] In some examples, the actuator 112 may move the second frame 114 relative to the first frame 110 based on the user's body position, the duration of use of the HMD 100, etc. For example, the HMD 100 may anticipate that the user desires a more immersive experience with better optical quality when sitting or lying down, and use the actuator 112 to reduce the distance between the second frame 114 and the first frame 110. The HMD 100 may anticipate that the user desires a less immersive experience and less attention to optical quality when standing or moving, and use the actuator 112 to increase the distance between the second frame 114 and the first frame 110. This may also improve comfort when the user is moving while wearing the HMD 100 by increasing the distance of the display 102 from the user's face. When the HMD 100 is worn for a long period of time, the HMD 100 may adjust the distance between the second frame 114 and the first frame 110 via the actuator 112 to adjust the pressure exerted by the HMD 100 on the user's head 101, thereby improving user comfort.

[0043] In some examples, the actuator 112 may be used to position the second frame 114 relative to the first frame 110 based on a user profile stored in the HMD 100. The user profile may be specific to an individual user of the HMD 100 and may be selected by the user or automatically selected based on the user's physical characteristics. The user profile may include the user's preference for the relative position of the second frame 114 and the first frame 110. The user profile may be specific to the type of activity selected when using the HMD 100. The user profile may be updated over time based on user feedback and the analysis of the user by the HMD 100 while the user is using the HMD 100.

[0044] The actuator 112 may be positioned at an intermediate position along the strip 116, the band 118, and / or the cover 120. For example, the strip 116 may be coupled to the display 102 and / or the second frame 114, and the actuator 112 may be disposed at an intermediate position along the length of the strip 116. In some examples, the band 118 may be coupled to the display 102 and / or the second frame 114 (e.g., the strip 116 may be omitted and the band 118 may be directly coupled to the display 102 and / or the second frame 114), and the actuator 112 may be disposed at an intermediate position along the length of the strip 116. In some examples, the cover 120 may be coupled to the display 102 and may extend distally at least partially around the actuator 112 to be coupled to the face interface 106. Thus, adjusting the relative position of the first frame 110 and the second frame 114 may adjust the length of the strip 116, the band 118, and / or the cover 120. The strip 116, the band 118, and / or the cover 120 may be formed of a flexible elastic material, may include telescoping elements, may include bellows-shaped elements, etc.

[0045] Although the actuator 112 has been described as being coupled to the first frame 110 and the second frame 114, the relative position of the display 102 with respect to the user's eyes can be adjusted by actuators disposed at different orientations of the HMD 100. In some examples, the first frame 110 can be omitted, and the second frame 114 can be coupled to the face interface 106 by the actuator 112. In some examples, the first frame 110 can be omitted, the second frame 114 can be coupled to the face interface 106 by the connector 108, and the strip 116 can be coupled to the display 102 by the actuator 112. In some examples, the first frame 110 can be omitted, the second frame 114 can be coupled to the face interface 106 by the connector 108, and the strip 116 can be coupled to the device seal 122 by the actuator 112.

[0046] Figure 2 A side view of the HMD 200 worn on the user's head 201 is illustrated. The HMD 200 includes a display 202 adjustably coupled to a device seal 204. The HMD 200 can be the same as or similar to the HMD 100 illustrated and discussed with respect to Figure 1A and Figure 1B including the same or similar components. For example, the HMD 200 includes a display 202 coupled to the device seal 204, a strip 206 coupled to the display 202 and / or the device seal 204, and a band 208 coupled to the strip 206. The position of the display 202 relative to the device seal 204 can be adjusted by actuators that can be coupled between the display 202 and the device seal 204, or between the display 202 and the strip 206.

[0047] Figure 2 The movement of the display 202 relative to the device seal 204 is illustrated, which can be provided by actuators coupled to the display 202 and either the device seal 204 and / or the strip 206. The distance between the display 202 and the device seal 204 can be adjusted in a direction 210 parallel to the longitudinal axis of the strip 206 and perpendicular to the display surface of the display 202. The pitch angle between the display 202 and the device seal 204 can be adjusted in a direction 212 about a pitch axis 214 parallel to the longitudinal axis of the display 202. The yaw angle between the display 202 and the device seal 204 can be adjusted in a direction 216 about a yaw axis 218 perpendicular to the longitudinal axis of the display 202 and the longitudinal axis of the strip 206.

[0048] The actuator may be coupled between the display 202 and the device seal 204, or between the display 202 and the strip 206. In an example where the actuator is coupled between the display 202 and the device seal 204, the device seal 204 may include a first frame to which the actuator may be coupled, the display 202 may include a second frame, and the actuator may be coupled to the second frame. The actuator may adjust the relative position of the display 202 and the device seal 204 by adjusting the relative position of the second frame and the first frame, as discussed above with respect to Figure 1A and Figure 1B . In an example where the actuator is coupled between the display 202 and the strip 206, the actuator may be coupled to the strip 206 and the frame of the display 202. The actuator may adjust the relative position of the display 202 and the device seal 204 by adjusting the relative position of the frame of the display and the strip 206.

[0049] Any number of actuators may be coupled between the display 202 and the device seal 204, or between the display 202 and the strip 206. Providing a greater number of actuators may increase the cost of the HMD 200 and may provide control over a greater number of variables in the relative positions of the display 202 and the device seal 204. For example, a single actuator may provide control over the relative positions of the display 202 and the device seal 204 in the direction 210; two actuators may provide control over the relative positions of the display 202 and the device seal 204 in the directions 210 and 212 or 216; three actuators may provide control over the relative positions of the display 202 and the device seal 204 in the directions 210, 212, and 216. The actuator may be oriented in the direction 210, a direction parallel to the pitch axis 214, a direction parallel to the yaw axis 218, or any other direction. Linkages may be provided between the display 202 and the device seal 204 or between the display 202 and the strip 206 to control the relative movement of the display 202 and the device seal 204 regardless of the orientation of the actuator.

[0050] Figures 3A through 3C HMDS 300A - 300C including various actuators 308A - 308C are respectively illustrated. HMDS 300A - 300C may be associated with respect to Figures 1A through 2The exemplified and discussed HMDs 100, 200 are the same or similar and include the same or similar components. For example, the HMDs 300A - 300C may include a display 302 that includes a display 304. The display 302 may be coupled to a display frame 306. A strip 312 may be coupled to the display 302, the display frame 306, and / or a device seal 310. The actuators 308A - 308C may be coupled to the display 302 and the device seal 310, coupled to the display 302 and the strip 312, or may be disposed at an intermediate position on the strip 312. The actuators 308A - 308C may be used to adjust the position of the display 302 relative to the device seal 310 (such as the distance in direction 314 between the display 302 and the device seal 310), and the relative angle between the display 302 and the device seal 310.

[0051] In Figure 3A it, the actuator 308A may include a motor or other linear actuator. The actuator 308A may provide precise, controlled actuation of the movement in direction 314 between the display 302 and the device seal 310. Multiple actuators 308A may be included to provide control of the relative position of the display 302 and the device seal 310 in additional dimensions. The actuator 308A may be an automatic actuator that is controlled by the HMD 300A in response to content provided by the HMD 300A, feedback provided by sensors of the HMD 300A, user selections provided through the HMD 300A, etc. The actuator 308A may be a non - reversibly drivable motor.

[0052] In Figure 3BIn [the example], the actuator 308B may include a ratchet or detent-based extension. In some examples, the actuator 308B may include a ratchet and pawl that are non-backdrivable in one or both directions. In some examples, the actuator 308B may include a pin and hole arrangement that is non-backdrivable in two directions. For example, holes 316 may be provided along the length of the post of the actuator 308B, and pins may be inserted into the corresponding holes 316 to maintain the desired position between the display 302 and the device seal 310. The post may be coupled to the display 302, and the pins may be coupled to the device seal 310 or the strip 312, or vice versa. In some examples, the actuator 308B may include a fastener and may be non-backdrivable in two directions. The actuator 308B may provide a discrete amount of movement of the position of the display 302 relative to the device seal 310 in the direction 314. The actuator 308B may engage or disengage with a dial, a button, etc. The actuator 308B may disengage from the button and engage through a spring. Multiple actuators 308B may be included to provide control of the relative position of the display 302 and the device seal 310 in additional dimensions. The actuator 308B may be a manual actuator, and the HMD 300B may provide commands or instructions to the user to adjust the actuator 308B. The user may actuate the actuator 308B in response to content provided by the HMD 300B, feedback provided by the sensors of the HMD 300B, user selections provided through the HMD 300B, etc.

[0053] In Figure 3CIn [the device], the actuator 308C may include a pop-out extension. The actuator 308C can be a helical spring type, a pneumatic spring type, a chemical spring type, etc. The actuator 308C can be used, for example, in a situation or event where the relative positioning of the modified display 302 with respect to the user is about to occur, to quickly move the display 302 away from the device seal 310 in the direction 314. The sensors and software of the HMD 300C can detect objects around the HMD 300C and the movement of the user of the HMD 300C, and can detect or anticipate the fall of the user of the HMD 300C or the interaction with objects around the HMD 300C. When the expected action or environmental conditions warrant, the HMD 300C can trigger the actuator 308C to move the display 302 away from the device seal 310 and the user's face. In other words, the controller of the HMD 300C can trigger the actuator 308C to move the display 302 away from the device seal 310 by sending a signal to the actuator 308C, so that the actuator 308C moves the display 302 away from the device seal 310 in response to the expected action or environmental conditions. In some cases, such triggering may include releasing a pin, ratchet, button, other fastener, etc. that holds the actuator 308C in the initial position, so that the actuator 308C moves the display 302 away from the device seal 310. This can ensure a comfortable distance between the components of the display and the user's face when wearing the HMD 300C. The actuator 308C can be held in place by a stop device (e.g., a pin, ratchet, button, other fastener, etc.), and when the HMD 300C detects environmental conditions that will modify the relative positioning of the display 302 with respect to the user, the stop device can be released, thus triggering the actuator 308C. The actuator 308C can be non-reverse drivable, or can be reverse driven by a variable amount of force (e.g., the actuator can include a spring with variable stiffness), which can allow some controlled movement between the display 302 and the device seal 310. The actuator 308C can be an automatic actuator, and these automatic actuators pop the display 302 away from the device seal 310 in a controlled manner in response to a signal from the HMD 300C.

[0054] Figures 4A through 4C Illustrated are HMDs 400.i - 400.iii (collectively referred to as HMD 400) having actuators 408 in different positions. The HMDs 400.i - 400.iii can be related to Figures 1A through 3CThe exemplified and discussed HMDs 100, 200, 300A - 300C are the same or similar and include the same or similar components. For example, the HMDs 400.i - 400.iii may include a display 402, which includes a display 404. The display 402 may be coupled to a display frame 406. A strip 412 may be coupled to the display 402, the display frame 406, and / or a device seal 410. An upper actuator 408U and a lower actuator 408L may be coupled to the display 402 and the device seal 410, coupled to the display 402 and the strip 412, or may be disposed at an intermediate position on the strip 412. The actuator 408 may be used to adjust the position of the display 402 relative to the device seal 410 (such as the distance between the display 402 and the device seal 410), and the relative angle between the display 402 and the device seal 410. Figures 4A through 4C The actuator 408 and the HMD are respectively illustrated in a first position i, a second position ii, and a third position iii.

[0055] In Figure 4A , the upper distance 414U.i defined by the upper actuator 408U.i and the lower distance 414L.i defined by the lower actuator 408L.i may be the same and relatively small. In Figure 4B , the upper distance 414U.ii defined by the upper actuator 408U.ii and the lower distance 414L.ii defined by the lower actuator 408L.ii may be the same and relatively large. In Figure 4C , the upper distance 414U.iii defined by the upper actuator 408U.iii may be greater than the lower distance 414L.iii defined by the lower actuator 408L.iii. As exemplified in Figure 4C , this changes the pitch angle of the display 402 relative to the device seal 410. The HMD 400 may also include left and right actuators 408 that can change the yaw angle of the display 402 relative to the device seal 410. Any number of actuators 408 may be included to change the relative position of the display 402 and the device seal 410 in any number of dimensions.

[0056] In Figures 4A through 4C 's example, the display 402 is coupled to the strip 412. As Figures 4A through 4CIllustrated in the example, when the position of the display 402 is adjusted relative to the device seal 410, the length of the strip 412 can be changed. This can be achieved by providing an actuator 408 at an intermediate position along the strip 412, by coupling the actuator 408 between the display 402 and the strip 412, or by including flexible materials, accordion-shaped materials, telescoping features, etc. in the strip 412. In some examples, the strip 412 can be coupled to the device seal 410, in which case the strip 412 can be rigid and not change when the actuator 408 moves. In some examples, the device seal 410 can include a cover that prevents ambient light from penetrating between the display 402 and the user's face. The cover can include flexible materials, accordion-shaped materials, telescoping features, etc., such that the cover blocks ambient light regardless of the position of the actuator 408.

[0057] To the extent applicable to the present technology, data collected and used from various sources can be used to improve the delivery of heuristic content or any other content that a user may be interested in. The present disclosure anticipates that, in some instances, the 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 can include demographic data, location-based data, phone numbers, email addresses, IDs, home addresses, 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.

[0058] The present disclosure recognizes that the use of such personal information data in the technology of the present invention can be used to benefit the user. For example, the personal information data can be used to deliver target content that the user is more interested in. Thus, the use of such personal information data enables the user to have planned control over the delivered content. In addition, the present disclosure also anticipates other uses of personal information data that are beneficial to the user. For example, health and fitness data can be used to provide insights into the user's overall health condition, or can be used as positive feedback for individuals who use technology to pursue health goals.

[0059] The present disclosure anticipates that entities responsible for the collection, analysis, disclosure, transmission, storage, or other use of such personal information data will comply with sound privacy policies and / or privacy practices. Specifically, such entities should implement and adhere to privacy policies and privacy practices that are recognized as meeting or exceeding industry or government requirements for maintaining the privacy and security of personal information data. Such policies should be accessible to users and should be updated as the collection and / or use of data changes. Personal information from users should be collected for legitimate and reasonable entity purposes and should not be shared or sold outside of those legitimate purposes. Additionally, such collection / sharing should occur after receiving informed consent from the user. Further, such entities should consider taking any necessary steps to protect and secure access to such personal information data and to ensure that other entities with access to personal information data comply with the privacy policies and procedures of other entities. Additionally, such entities may subject themselves to third-party assessments to demonstrate their compliance with widely accepted privacy policies and privacy practices. Moreover, the policies and practices should be adapted to the specific types of personal information data being collected and / or accessed and to the applicable laws and standards, including considerations of particular 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. Thus, different privacy practices should be asserted for different types of personal data in each country.

[0060] Notwithstanding the foregoing, the present disclosure also anticipates embodiments where users selectively block the use or access of personal information data. That is, the present disclosure anticipates that hardware elements and / or software elements may be provided to prevent or block access to such personal information data. For example, in the case of an advertising delivery service, the inventive technology may be configured to allow a user to select "opt-in" or "opt-out" of participating in the collection of personal information data during or at any time after registering for the service. In another example, a user may choose not to provide emotion-related data for a targeted content delivery service. In another example, a user may choose to limit the length of time emotion-related data is kept or to completely prohibit the development of underlying emotional states. In addition to providing "opt-in" and "opt-out" options, the present disclosure also anticipates providing notifications related to the access or use of personal information. For example, a user may be notified when downloading an application that the user's personal information data will be accessed, and then reminded again just before the personal information data is accessed by the application.

[0061] 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 inadvertent or unauthorized access or use. Once the data is no longer needed, the risk can be minimized by restricting data collection and deleting the data. Additionally, and when applicable, including in certain health-related applications, data de-identification can be used to protect the privacy of the user. De-identification can be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of the data stored (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 among users), and / or other methods.

[0062] Accordingly, 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 the various embodiments may also be implemented without access to such personal information data. That is, the various embodiments of the inventive technology will not fail to operate due to the lack of all or a portion of such personal information data. For example, preferences can be inferred by relying on non-personal information data or an absolute minimum amount of personal information such as the content requested by a device associated with the user, other non-personal information available to a content delivery service, or publicly available information, and content can be selected and delivered to the user based thereon.

[0063] For purposes of illustration, the foregoing description uses specific names to provide a thorough understanding of the described embodiments. However, it will be apparent to those skilled in the art that no specific details are required in order to practice the described embodiments. Accordingly, the foregoing description of the specific embodiments described herein is presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the embodiments to the precise forms disclosed. It will be apparent to those of ordinary skill in the art that many modifications and variations are possible in light of the above teachings.
