摘要： Systems and methods are provided herein for providing spatial audio cues for notifying a user of a user interface (“UI”) element in augmented reality (“AR”). This may be accomplished by a system determining a location and orientation of a device, and then determining an estimated augmented reality view using the location and orientation of the device. The system may then determine whether a UI element is within the augmented reality view. If the UI element is within the augmented reality view, the system can play an audio cue signaling a position of the UI element using audio spatialization. After hearing the audio cue, the user may then view the UI element in AR using the device.

摘要： Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program, method, and user interface to facilitate a camera sharing session between two or more users. A request for an image depicting an image target is received from a first device associated with a first user. A notification of the request is transmitted to a second device associated with a second user. Image data comprising at least one image generated by a camera communicatively coupled to the second device is received from the second device and the image data is transmitted to the first device. A reward is provided to the second user based on the image data including a depiction of the image target.

摘要： An optical module and an electronic device are disclosed. The optical module comprises a beam splitting assembly, a beam combining assembly, a first dimmer assembly and a second dimmer assembly. The beam splitting assembly is configured to divide the incident light into a first light beam and a second light beam that propagate in different directions. The first dimming assembly is located on the light path of the first light beam, and the second dimming assembly is located on the light path of the second light beam. The beam combining assembly is located at the intersection position, so that the first light beam and the second light beam entering the beam combining assembly exit concurrently along the same direction.

摘要： Methods and apparatuses for applying anti-reflective structures to a waveguide of an augmented reality display device include producing two initial molds: one formed with high precision for diffractive optical structures, and one formed with lower precision for anti-reflective structures. The two initial molds are imprinted into a single resist layer to form an integrated mold, which is then usable to simultaneously form both diffractive optical structures and anti-reflective structures. Accordingly, the cost of producing the anti-reflective structures is minimized while the efficiency of forming the diffractive optical structures and anti-reflective structures is maximized.

摘要： An adjustment image of a projected image is captured by a disparity image sensor. A first defocus factor in generated response to comparing the adjustment image with a reference image driven onto a display projector assembly the generated the projected image. A second defocus factor is generated in response to an alignment of a first intensity profile of the adjustment image and a second intensity profile of the adjustment image. A focusing lens of the display projector assembly is adjusted in response to at least one of the first defocus factor and the second defocus factor.

摘要： An optical system and a head mounted display are disclosed. The optical system comprises: a third lens, a second lens and a first lens arranged successively along a propagation direction of incident light. There are two adjacent Fresnel surfaces in the optical system, and at least one of the Fresnel surfaces has a curved base. The present disclosure provides a solution of short-focus and lightweight optical structure, in which, compared with a flat base, the use of Fresnel surface having a curved base can improve the imaging quality to a certain extent, and can reduce the total optical length and the total weight of the optical system.

摘要： A method for coating an optical substrate with an anti-reflection multilayered stack is provided. The method includes depositing a stack of dielectric layers having alternate index of refraction over a substrate, to form an anti-reflective coating. The method also includes depositing a first layer of low refractive index material on top of the stack of dielectric layers, etching the first layer of low refractive index material with a solvent at a selected temperature, and conformally depositing a sealant material over the first layer of low refractive index material to complete the anti-reflective coating. A headset for virtual reality, augmented reality, or mixed reality applications including optical components having an anti-reflection coating fabricated per the above method is also provided.
