Detailed Description

An electronic device, such as a head-mounted device, may have a display for displaying an image and a lens for presenting the image to an eye box for viewing by a user. Different users have different eyeglass prescriptions and facial shapes. To accommodate prescriptions and facial shapes for a given application, the electronic device may be provided with removable portions tailored to a given user. The removable portion (which may sometimes be referred to as a removable housing portion or removable light seal) may include a user-customized lens (which may sometimes be referred to as a prescription lens or vision correction lens) and may have a shape that matches the face of the user.

FIG. 1 is a schematic diagram of an exemplary electronic device of the type that may include a removable custom fitting light seal with a vision correcting lens. The device 10 of fig. 1 may be a head-mounted device (e.g., goggles, glasses, helmets, and/or other head-mounted devices). In one exemplary configuration, the device 10 is a head-mounted device such as a pair of goggles (sometimes referred to as virtual reality goggles, mixed reality goggles, augmented reality glasses, or the like).

As shown in the exemplary cross-sectional top view of the device 10 of fig. 1, the device 10 may have a housing, such as the housing 12 (sometimes referred to as a head-mounted support structure or head-mounted support). The housing 12 may include a front portion, such as front portion 12F, and a removable rear portion, such as rear portion 12R. When the device 10 is worn on the user's head, the rear portion 12R abuts the user's face and helps block stray light from reaching the user's eyes. Because of these light sealing properties, the rear portion 12R may sometimes be referred to as a light seal. To improve comfort, the shape of the portion 12R may match the shape of the user's face, so the removable rear portion 12R may sometimes be referred to as a custom fit removable light seal or custom fit removable housing portion.

The front 12F of the device 10 has a main portion 12M (sometimes referred to as a main unit) and other head-mounted support structures such as a headband 12T. The main portion 12M may have a rigid housing formed of a housing wall of polymer, glass, metal, and/or other materials. When the housing 12 is worn on the head of a user, the front of the housing 12 may face outwardly away from the user, the rear of the housing 12 may face the user, and the eyes of the user may be located in the eye box 36.

The device 10 may have electrical and optical components for displaying images to the eye box 36 when the device 10 is worn. These components may include left and right optical assemblies 20 (sometimes referred to as optical modules). Each optical assembly 20 may have an optical assembly support 38 (sometimes referred to as a lens barrel or optical module support) and rails 22 along which the optical assemblies 20 may slide to adjust the optical assembly-to-optical assembly spacing to accommodate different user pupils.

Each assembly 20 may have a display 32 with an array of pixels for displaying an image and a lens 34 (sometimes referred to as a main lens, a fixed lens, or a system lens). In each assembly 20, the display 32 and the lens 34 may be coupled to and supported by a support 38. During operation, images displayed by display 32 may be presented to eye box 36 through lens 34 for viewing by a user. Some users have vision defects (e.g., refractive errors, such as myopia, hyperopia, and/or astigmatism). These vision defects may be corrected with a user-specific prescription lens, such as vision correction lens 50. As shown in fig. 1, lens 50 may be aligned with lens 34 such that an image displayed by display 32 is presented to eye box 36 through lens 34 and overlapping lens 50.

As shown in fig. 1, the rear portion 12R may include a rear housing structure, such as a rear housing layer 52. Layer 52 may include rigid portions (e.g., polymer layers, polymer frames, etc.) and/or flexible portions (e.g., flexible polymer layers, flexible fabric layers, etc.). Layer 52 (sometimes referred to as a custom fit layer or custom fit rear housing structure) may have a shape that is custom (or semi-custom) to fit the facial shape of the user (e.g., such that layer 52 exactly or closely matches the facial features of the user such as the user's nose size and shape, cheek position, forehead shape, etc.). By tailoring layer 52 in this manner, a rear 12R that is different for different users may be created, allowing each user to choose a rear 12R that fits their face and is thus comfortable for the user.

The portion 12R may have magnets, clips, and/or other temporary attachment structures that allow the portion 12R to be removably attached to the front portion 12F. For example, the rear portion 12R may have magnets 54 that mate with corresponding magnets 56 attached to the main portion 12M of the front portion 12F. In the event that it is desired to share the device 10 between multiple users, each user may be provided with a different respective rear 12R tailored to that user. When a given user is ready to use device 10, the back 12R of the given user may be magnetically attached or otherwise removably attached to the front 12F, thereby customizing device 10 for the given user.

Each rear portion 12R may be provided with a vision correction lens 50 tailored to the user associated with the rear portion. The lens 50 may be attached to the layer 52 using a press fit connection, clips, adhesive, screws, mating threaded lens holders, and/or other permanent and/or semi-permanent attachment mechanisms. During normal use, lens 50 generally does not need to be removed from rear portion 12R. Instead, the posterior portion 12R, which includes both the face-customized structure of layer 52 and the eye-customized structure of lens 50, may be attached to and removed from the anterior portion 12F as a unit. This simplifies the process of customizing the device 10 for different users.

The walls of the housing 12 may separate an interior region 28 of the device 10 from an exterior region 30 surrounding the device 10. In the interior region 28, the optical assembly 20 may be mounted on the rail 22. The guide rail 22 may be attached to the central housing portion 12C. If desired, the outer ends of the rails 22 may be unsupported (e.g., the outer end portions of the rails 22 may not directly contact the housing 12 such that the ends float relative to the housing 12 in the interior region 28).

The device 10 may include control circuitry and other components such as component 40. The control circuitry may include memory, processing circuitry formed by one or more microprocessors, and/or other circuitry. To support communication between the device 10 and external devices, the control circuitry may include wireless communication circuitry. The component 40 may include sensors such as force sensors (e.g., strain gauges, capacitive force sensors, resistive force sensors, etc.), audio sensors (such as microphones), touch sensors and/or proximity sensors (such as capacitive sensors), optical sensors (such as optical sensors that emit and detect light), ultrasonic sensors and/or other touch sensors and/or proximity sensors, monochrome and color ambient light sensors, image sensors, sensors for detecting position, orientation, and/or motion (e.g., accelerometers, magnetic sensors (such as compass sensors, gyroscopes, and/or sensors such as inertial measurement units that include some or all of these sensors)), radio frequency sensors, depth sensors (e.g., structured light sensors and/or depth sensors based on stereoscopic imaging devices), optical sensors (such as light detection and ranging (laser radar) sensors that collect time-of-flight measurements), humidity sensors, vision inertial sensors, and/or other sensors. In some arrangements, the device 10 may use sensors to collect user input (e.g., button press input, touch input, etc.). The sensor may also be used to collect environmental motion (e.g., device motion measurements, temperature measurements, ambient light readings, etc.).

The optical component 20 may have a gaze tracker sensor 62 (sometimes referred to as a gaze tracker). The sensor 62 may include one or more light sources, such as infrared light emitting diodes that emit infrared light to illuminate the eyes of the user in the eye box 36. The sensor 62 also includes an infrared camera for capturing images of the user's eyes and measuring the reflection (flash) of infrared light from each of the infrared light sources. By processing these eye images, the sensor 62 may track the user's eyes and determine the user's gaze point.

The spacing between the eyes of different users is different. The eye-to-eye spacing of users is referred to as their interpupillary distance. To accommodate users with different interpupillaries, the spacing between the left and right optical assemblies 20 in the device 10 may be adjusted. The device 10 may have a left actuator and a right actuator (e.g., a motor), such as motor 48. Each motor 48 may be used to rotate an elongated threaded shaft, such as a screw 44. A nut 46 is provided on each screw 44. The nut has threads that engage threads on the threaded rod 44. When the screw is rotated, the nut on the screw is driven in either the +X or-X direction (depending on whether the screw is rotated clockwise or counter-clockwise). This, in turn, moves the optical assembly 20 attached to the nut in either the +x or-X direction along its optical assembly rail 22. Each assembly 20 (e.g., support 38) may have a portion that receives one of the rails 22 such that the assembly is guided along the rail. By controlling the movement of the motor 48, the spacing between the left and right optical components of the device 10 can be adjusted to accommodate the interpupillary distances of different users. For example, if the user has closely spaced eyes, the assemblies 20 may be moved inwardly (toward each other) and if the user has widely spaced eyes, the assemblies 20 may be moved outwardly (away from each other).

In addition to adjusting the spacing between the assemblies 20 such that the display 32 and the lenses 34 are spaced apart a distance that matches the user's pupil distance, the lens-to-lens spacing of the vision correction lens 50 in the rear portion 12R should match the user's pupil distance. The lens-to-lens spacing of the lenses 50 on the rear portion 12R may be adjustable or fixed. In the exemplary adjustable lens pitch arrangement, the rear layer 52 is flexible such that the layer 52 can stretch to accommodate variations in the lens-to-lens pitch of the lens 50. In an exemplary fixed lens spacing arrangement, the rear layer 52 may have one or more rigid portions that resist or prevent variations in spacing between the lenses 50.

As an example, consider a situation in which the rear portion 12R is customized to accommodate a person having a small nose and a large interpupillary distance. In this case, the layer 52 is provided with a nose bridge portion having a small nasal recess, and the lens 50 is mounted on the layer 52 remotely. When a user desires to use the device 10, the rear layer 12R is moved to near the rear of the front 12F so that the rear 12R may be coupled to the front 12F (e.g., the magnet 54 on the rear 12R may be moved into alignment with the magnet 56 on the front so that the magnetic attraction pulls the rear 12R onto the front 12F). The motor 48 may adjust the position of the optical assembly 20 to match the user's pupil distance to ensure that the lenses 34 are spaced the same amount as the lenses 50 on the rear portion 12R.

The device 10 (e.g., circuitry in the front 12F) may obtain information about the proper spacing for the components 20 during or prior to attaching the rear 12R. As an example, a gaze tracker sensor 62 (e.g., an image sensor in the sensor 62) or other image sensor may capture an image of a fiducial, bar code, or other information (see, e.g., fiducial 64) on one or in the vicinity of one or both of the lenses 50. The fiducials 64 may act as codes that contain information about the pupil distance of the user associated with the rear portion 12R and thus the spacing between the lenses 50 on the rear portion 12R. In response to obtaining the pupil distance information from section 12R, motor 48 may adjust the pitch of assembly 20 to match the pitch of lens 50 and the pupil distance of the user. Other arrangements may be used to obtain the pupil distance information from the rear portion 12R if desired. As an example, the device 10 (e.g., front 12F) may have a sensor such as sensor 58 that reads encoded pupil information from a code (encoded information) 60 on portion 12R using optical sensing, radio frequency sensing, magnetic sensing, resistive sensing, and/or other types of sensing. If desired, other components (see, e.g., component 40) may include wireless communication circuitry (e.g., near field communication circuitry orA circuit). The radio circuit may communicate wirelessly with a corresponding wireless transceiver, such as transceiver 61 in portion 12R. Encoded information (e.g., a code representing the pupil distance of portion 12R) may be communicated from portion 12R to portion 12F by wireless communication (e.g., near field communication, local area network wireless communication, and/or other wireless communication) such that motor 48 may adjust the pitch of optical assembly 20 to match the lens-to-lens pitch of lens 50 in portion 12R (e.g., to match the pupil distance of the user). As demonstrated by these examples, portion 12F (e.g., sensor and/or wireless transceiver circuitry) may extract pupil distance information from the customized light seal (portion 12R) and thus motor 48 may be used to adjust the optical assembly pitch of assembly 20.

Fig. 2 is a rear view of a portion of rear portion 12R, showing how lens 50 may be mounted to layer 52. Layer 52 may comprise flexible and/or rigid materials. If desired, layer 52 may include a rigid frame structure, a foam ring (e.g., a soft peripheral ring that acts as a cushion between device 10 and the face of the user), and/or other structures (see, e.g., exemplary structure 52', which may include a cushion ring, a frame structure, a lens support, etc.). Layer 52 may have a custom fit adapted to provide comfort to a particular user (or group of similar users). For example, a custom fitting recess having a three-dimensional nose shape (such as a nose bridge portion NB) may be configured to rest comfortably on or near the nose of a user. Other portions of the rear portion 12R (e.g., the overall shape of the layer 52) may also be customized to accommodate the face of the user. The lenses 50 may maintain a fixed lens-to-lens spacing in the layer 52 (e.g., in the case of adjusting the spacing between the assemblies 20 before the rear portion 12R is attached to the front portion 12F), or the layer 52 may be flexible such that the spacing between the lenses 50 may be adjusted as the lenses 50 travel with the assemblies 20 (e.g., in the case of the lenses 50 being snapped into place or otherwise coupled to the support 38 before the assemblies 20 move with the motor 48).

The motor 48 may be omitted if desired. In this type of arrangement, the front 12F and rear 12R may be provided with structures that cooperate to adjust the optical assembly spacing to match the user's pupil distance (e.g., by moving the assembly 20 by an amount specified by the rear 12R attached to the device 10). As an example, consider the arrangement of fig. 3. Fig. 3 is a top view of a portion of the apparatus 10, showing how the rear portion 12R and the front portion 12F may have mating mechanical structures, such as a gear 70 in the front portion 12F and a toothed track 72 in the rear portion 12R. Gear 70 may be attached to one or more shafts, such as shaft 44. When portion 12R is not present, a spring, such as spring 76, may be used to rotate shaft 44 such that optical assemblies 20 are spaced apart a maximum resting distance. When rear portion 12R is attached to portion 12F, track 72 and gear 70 interact to adjust the spacing between assemblies 20.

The toothed track 72 in the rear portion 12R may have a length L that matches the separation distance between the lenses 50 in the rear portion 12R and thus matches the pupil distance of the user. As an example, if the spacing between lenses 50 is small (because portion 12R has been customized for users with small interpupillary distances), length L may be larger. If the spacing between lenses 50 is large (and the user's pupil distance is large), the length L may be smaller. When portion 12R is attached to portion 12F (e.g., by sliding portion 12R in direction 74), the teeth on toothed track 72 will engage corresponding teeth in gear 70, rotating shaft 44 about axis 80 by an amount proportional to length L. Rotation of the shaft 44 will in turn rotate the nut 46 of fig. 1, thereby moving the optical assemblies 20 toward each other by an amount proportional to L. When L is small, the optical assemblies 20 will move toward each other by a correspondingly small amount, and the resulting spacing between the assemblies 20 will match the large user pupil distance. When L is larger, the optical assemblies 20 will move toward each other by a correspondingly larger amount, and the resulting spacing between the assemblies 20 will match the small user pupil distance. Other types of cooperating mechanical structures in the portions 12F and 12R (e.g., pin and cone based structures, worm gear and mating toothed member based structures, ramp and wheel based structures, etc.) may be used to mechanically adjust the spacing of the assemblies 20 when the portion 12R is attached to the portion 12F, if desired. The use of cooperating mechanical structures such as toothed rail 72 and gear 70 of fig. 3 is illustrative.

Fig. 4 and 5 are cross-sectional side views of portions of the apparatus 10, showing how the lenses 50 and 34 may be mounted. In the exemplary arrangement of fig. 4, the lens 34 is attached to the support 38 using an adhesive 90. Lens surface 92 and support surface 94 serve as reference surfaces (fiducials) to help accurately establish a desired spacing between lens 34 and display 32 in support 38. The surface 92 may be formed on a protruding portion of the lens 34, such as portion 34P, may be formed on a non-protruding flat portion of the lens 34, may be formed on a beveled edge of the lens 34, and/or may be formed on other portions of the lens 34. Portion 12R may have a support such as a portion of layer 52 (e.g., a frame structure or other portion 52' of layer 52, etc.) having a reference surface such as surface 96 attached to a corresponding reference surface such as surface 98 of lens 50 with adhesive 100. The surface 98 may be formed on a protruding portion of the lens 50, a flat portion of a non-protruding portion of the lens 50, a beveled edge of the lens 50, and/or other portions of the lens 50. When portion 12R is attached to portion 12F, the mating reference surfaces of layer 52 and support 38 meet at interface 102. The location of interface 102 relative to surfaces 96 and 98 and relative to surfaces 92 and 94 helps to accurately establish the desired spacing between lenses 50 and 34 and between lenses 50 and the display in support 38.

With the mounting arrangement of fig. 5, portion 12R (e.g., layer 52) may have a reference surface attached to a corresponding reference surface of lens 50 with adhesive 120, and may have a reference surface attached to lens 34 with adhesive 122. In this type of configuration, lens 34 travels with lens 50 in portion 12R, and the remainder of assembly 20 forms part of portion 12F. Magnets or other removable attachment structures may be used to attach portions 12R and 12F (e.g., at interface 124 between support 38 and lens 34). In another embodiment, both lens 50 and lens 34 may be fixedly attached to support 38 such that optical assembly 20 forms part of removable rear housing portion 12R, while the remainder of device 10 is part of spaced front portion 12F.

In some embodiments, the sensor may collect personal user information. To ensure that the privacy of the user is preserved, all applicable privacy rules should be met or exceeded, and best practices for handling personal user information should be followed. Users may be allowed to control the use of their personal information according to their preferences.
