Abstract

A display system aligns the location of its exit pupil with the location of a viewer's pupil by changing the location of the portion of a light source that outputs light. The light source may include an array of pixels that output light, thereby allowing an image to be displayed on the light source. The display system includes a camera that captures image(s) of the eye and negatives of the eye image(s) are displayed by the light source. In the negative image, the dark pupil of the eye is a bright spot which, when displayed by the light source, defines the exit pupil of the display system, such that image content may be presented by modulating the light source. The location of the pupil of the eye may be tracked by capturing the images of the eye.

Abstract

A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.

Abstract

A display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. The wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The images may be formed by an emissive micro-display. Each pixel formed by the micro-display may be formed by one of a group of light emitters, which are at different locations such that the emitted light takes different paths to the eye to provide different amounts of parallax disparity.

Abstract

Diffraction gratings provide optical elements, e.g., in a head-mountable display system, that can affect light, for example by incoupling light into a waveguide, outcoupling light out of a waveguide, and/or multiplying light propagating in a waveguide. The diffraction gratings may be configured to have reduced polarization sensitivity such that light of different polarization states, or polarized and unpolarized light, is incoupled, outcoupled, multiplied, or otherwise affected with a similar level of efficiency. The reduced polarization sensitivity may be achieved through provision of a transmissive layer and a metallic layer on one or more gratings. A diffraction grating may comprise a blazed grating or other suitable configuration.

Abstract

A display system includes a waveguide assembly having a plurality of waveguides, each waveguide associated with an in-coupling optical element configured to in-couple light into the associated waveguide. A projector outputs light from one or more spatially-separated pupils, and at least one of the pupils outputs light of two different ranges of wavelengths. The in-coupling optical elements for two or more waveguides are inline, e.g. vertically aligned, with each other so that the in-coupling optical elements are in the path of light of the two different ranges of wavelengths. The in-coupling optical element of a first waveguide selectively in-couples light of one range of wavelengths into the waveguide, while the in-coupling optical element of a second waveguide selectively in-couples light of another range of wavelengths. Absorptive color filters are provided forward of an in-coupling optical element to limit the propagation of undesired wavelengths of light to that in-coupling optical element.

A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive image information outputted by the HMD. For example, the HMD-to-eye vertical alignment may be different between the left and right eyes. The wearable device may determine if the HMD is level on the user's head and may then provide the user with a left-eye alignment marker and a right-eye alignment marker. Based on user feedback, the wearable device may determine if there is any left-right vertical misalignment and may take actions to reduce or minimize the effects of any misalignment.

Abstract

Several unique configurations for interferometric recording of volumetric phase diffractive elements with relatively high angle diffraction for use in waveguides are disclosed. Separate layer EPE and OPE structures produced by various methods may be integrated in side-by-side or overlaid constructs, and multiple such EPE and OPE structures may be combined or multiplexed to exhibit EPE/OPE functionality in a single, spatially-coincident layer. Multiplexed structures reduce the total number of layers of materials within a stack of eyepiece optics, each of which may be responsible for displaying a given focal depth range of a volumetric image. Volumetric phase type diffractive elements are used to offer properties including spectral bandwidth selectivity that may enable registered multi-color diffracted fields, angular multiplexing capability to facilitate tiling and field-of-view expansion without crosstalk, and all-optical, relatively simple prototyping compared to other diffractive element forms, enabling rapid design iteration.

Abstract

The disclosure describes an improved drop-on-demand, controlled volume technique for dispensing resist onto a substrate, which is then imprinted to create a patterned optical device suitable for use in optical applications such as augmented reality and/or mixed reality systems. The technique enables the dispensation of drops of resist at precise locations on the substrate, with precisely controlled drop volume corresponding to an imprint template having different zones associated with different total resist volumes. Controlled drop size and placement also provides for substantially less variation in residual layer thickness across the surface of the substrate after imprinting, compared to previously available techniques. The technique employs resist having a refractive index closer to that of the substrate index, reducing optical artifacts in the device. To ensure reliable dispensing of the higher index and higher viscosity resist in smaller drop sizes, the dispensing system can continuously circulate the resist.

Abstract

In an example method of forming a waveguide part having a predetermined shape, a photocurable material is dispensed into a space between a first mold portion and a second mold portion opposite the first mold portion. A relative separation between a surface of the first mold portion with respect to a surface of the second mold portion opposing the surface of the first mold portion is adjusted to fill the space between the first and second mold portions. The photocurable material in the space is irradiated with radiation suitable for photocuring the photocurable material to form a cured waveguide film so that different portions of the cured waveguide film have different rigidity. The cured waveguide film is separated from the first and second mold portions. The waveguide part is singulated from the cured waveguide film. The waveguide part corresponds to portions of the cured waveguide film having a higher rigidity than other portions of the cured waveguide film.

Abstract

Systems and methods for displaying a virtual reticle in an augmented or virtual reality environment by a wearable device are described. The environment can include real or virtual objects that may be interacted with by the user through a variety of poses, such as, e.g., head pose, eye pose or gaze, or body pose. The user may select objects by pointing the virtual reticle toward a target object by changing pose or gaze. The wearable device can recognize that an orientation of a user's head or eyes is outside of a range of acceptable or comfortable head or eye poses and accelerate the movement of the reticle away from a default position and toward a position in the direction of the user's head or eye movement, which can reduce the amount of movement by the user to align the reticle and target.

Abstract

Disclosed herein are systems and methods for setting, accessing, and modifying user privacy settings using a distributed ledger. In an aspect, a system can search previously stored software contracts to locate an up-to-date version of a software contract associated with a user based on a request for access to user data for the particular user. Then, the system determines that the user data is permitted to be shared. The system transmits, to a data virtualization platform, instructions to extract encrypted user data from a data platform. The system can then make available, to a data verification system, a private encryption key and details associated with the software contract to verify that the private encryption key and the user data match. Then the system transmits, to the data virtualization platform, the private encryption key so that the data virtualization platform can decrypt the encrypted user data.

Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using depth data to update camera calibration data. In some implementations, a frame of data is captured including (i) depth data from a depth sensor of a device, and (ii) image data from a camera of the device. Selected points from the depth data are transformed, using camera calibration data for the camera, to a three-dimensional space that is based on the image data. The transformed points are projected onto the two-dimensional image data from the camera. Updated camera calibration data is generated based on differences between (i) the locations of the projected points and (ii) locations that features representing the selected points appear in the two-dimensional image data from the camera. The updated camera calibration data can be used in a simultaneous localization and mapping process.

Abstract

Methods are disclosed for fabricating molds for forming waveguides with integrated spacers for forming eyepieces. The molds are formed by etching features (e.g., 1 μm to 1000 μm deep) into a substrate comprising single crystalline material using an anisotropic wet etch. The etch masks for defining the large features may comprise a plurality of holes, wherein the size and shape of each hole at least partially determine the depth of the corresponding large feature. The holes may be aligned along a crystal axis of the substrate and the etching may automatically stop due to the crystal structure of the substrate. The patterned substrate may be utilized as a mold onto which a flowable polymer may be introduced and allowed to harden. Hardened polymer in the holes may form a waveguide with integrated spacers. The mold may be also used to fabricate a platform comprising a plurality of vertically extending microstructures of precise heights, to test the curvature or flatness of a sample, e.g., based on the amount of contact between the microstructures and the sample.

The method also includes coating an interior surface and an exterior surface of each of the set of piezoelectric elements with a first conductive material. The method also includes providing a fiber optic element having an actuation region and coating the actuation region of the fiber optic element with a second conductive material. The method also includes joining the interior surfaces of the set of piezoelectric elements to the actuation region of the fiber optic element and poling the set of piezoelectric elements. The method also includes forming electrical connections to the exterior surface of each of the set of piezoelectric elements and the fiber optic element.
