摘要： A head-mounted apparatus include an eyepiece including a variable dimming assembly and a frame mounting the eyepiece so that a user side of the eyepiece faces a towards a user and a world side of the eyepiece opposite the first side faces away from the user. The dynamic dimming assembly selectively modulates an intensity of light transmitted parallel to an optical axis from the world side to the user side during operation. The dynamic dimming assembly includes a variable birefringence cell having multiple pixels each having an independently variable birefringence, a first linear polarizer arranged on the user side of the variable birefringence cell, the first linear polarizer being configured to transmit light propagating parallel to the optical axis linearly polarized along a pass axis of the first linear polarizer orthogonal to the optical axis, a quarter wave plate arranged between the variable birefringence cell and the first linear polarizer.

摘要： This disclosure is related to systems and methods for rendering audio for a mixed reality environment. Methods according to embodiments of this disclosure include receiving an input audio signal, via a wearable device in communication with a mixed reality environment, the input audio signal corresponding to a sound source originating from a real environment. In some embodiments, the system can determine one or more acoustic properties associated with the mixed reality environment. In some embodiments, the system can determine a signal modification parameter based on the one or more acoustic properties associated with the mixed reality environment. In some embodiments, the system can apply the signal modification parameter to the input audio signal to determine a second audio signal. The system can present the second audio signal to the user.

摘要： This disclosure describes in-plane switching mode liquid crystal geometric phase tunable lenses that can be integrated into an eyepiece of an optical device for the correction of non-emmetropic vision, such as in an augmented reality display system. The eyepiece can include an integrated, field-configurable optic arranged with respect to a waveguide used to project digital imagery to the user, the optic being capable of providing a tunable Rx for the user including variable spherical refractive power (SPH), cylinder refractive power, and cylinder axis values. In certain configuration, each tunable eyepiece includes two variable compound lenses: one on the user-side of the waveguide with variable SPH, cylinder power, and axis values; and a second on the world side of the waveguide with variable SPH.

摘要： A head mounted display can include a frame, an eyepiece, an image injection device, a sensor array, a reflector, and an off-axis optical element. The frame can be configured to be supported on the head of the user. The eyepiece can be coupled to the frame and configured to be disposed in front of an eye of the user. The eyepiece can include a plurality of layers. The image injection device can be configured to provide image content to the eyepiece for viewing by the user. The sensor array can be integrated in or one the eyepiece. The reflector can be disposed in or on the eyepiece and configured to reflect light received from an object for imaging by the sensor array. The off-axis optical element can be disposed in or one the eyepiece. The off-axis optical element can be configured to receive light reflected from the reflector and direct at least a portion of the light toward the sensor array.

摘要： In some embodiments, a near-eye, near-eye display system comprises a stack of waveguides having pillars in a central, active portion of the waveguides. The active portion may include light outcoupling optical elements configured to outcouple image light from the waveguides towards the eye of a viewer. The pillars extend between and separate neighboring ones of the waveguides. The light outcoupling optical elements may include diffractive optical elements that are formed simultaneously with the pillars, for example, by imprinting or casting. The pillars are disposed on one or more major surfaces of each of the waveguides. The pillars may define a distance between two adjacent waveguides of the stack of waveguides. The pillars may be bonded to adjacent waveguides may be using one or more of the systems, methods, or devices herein. The bonding provides a high level of thermal stability to the waveguide stack, to resist deformation as temperatures change.

摘要： This document describes imaging and visualization systems in which the intent of a group of users in a shared space is determined and acted upon. In one aspect, a method includes identifying, for a group of users in a shared virtual space, a respective objective for each of two or more of the users in the group of users. For each of the two or more users, a determination is made, based on inputs from multiple sensors having different input modalities, a respective intent of the user. At least a portion of the multiple sensors are sensors of a device of the user that enables the user to participate in the shared virtual space. A determination is made, based on the respective intent, whether the user is performing the respective objective for the user. Output data is generated and provided based on the respective objectives respective intents.

摘要： Systems and methods for presenting audio using an audio system supporting multiple modes of operation are disclosed. In some embodiments, elements of the audio system are configured to operate in the different modes. For example, the audio system is configured to operate in a first mode and a second mode. The audio system may be operating in the first mode or the second mode based on an application running on a system or a signal generated by the system.

摘要： Disclosed herein are systems and methods for presenting an audio signal associated with presentation of a virtual object colliding with a surface. The virtual object and the surface may be associated with a mixed reality environment. Generation of the audio signal may be based on at least one of an audio stream from a microphone and a video stream form a sensor. In some embodiments, the collision between the virtual object and the surface is associated with a footstep on the surface.

摘要： A pupil separation system includes an input surface, a central portion including a set of dichroic mirrors, a first reflective surface disposed laterally with respect to the central portion, and a second reflective surface disposed laterally with respect to the central portion. The pupil separation system also includes an exit face including a central surface operable to transmit light in a first wavelength range, a first peripheral surface adjacent the central surface and operable to transmit light in a second wavelength range, and a second peripheral surface adjacent the central surface and opposite to the first peripheral surface. The second peripheral surface is operable to transmit light in a third wavelength range.
