摘要： An audio system for near and far field signal enhancement that uses a contact transducer. The audio system includes a microphone array, the contact transducer, and a controller. The microphone array detects sounds from a local area. The sounds from the local area include a voice of a user of the audio system. The contact transducer may be in contact with the head of the user. The contact transducer detects tissue based vibrations that are generated by the user and pass through tissue of the user prior to being detected by the contact transducer. The controller identifies the voice of the user in the detected sounds using the detected tissue based vibrations and a model, and updates a sound filter based on the identified voice of the user. The audio content is modified using the updated sound filter, and is presented by at least one audio system.

摘要： A display panel has an array of pixels backlighted by a backlight including a lightguide and a plurality of out-coupling gratings. The locations of the out-coupling gratings are coordinated with positions of pixels in the array of pixels. The backlight may include a light-conducting transparent slab or an array of linear waveguides running parallel to the rows of the pixel array, with the gratings formed in the slab or in the waveguide. Wavelength composition and polarization of the light emitted by the waveguide may be matched to the transmission spectral bands and transmission polarization of the display panel.

摘要： In one embodiment, a computing system may receive, from a second computing system, video streams of a scene, the video streams including at least a first image and a second image that are simultaneously captured by a first camera and a second camera of the second computing system, respectively. The system may determine, using a sensor system, a viewpoint of a viewer with respect to a display region of a monoscopic display associated with the first computing system. The system may generate an output image of the scene by blending, according to blending proportions computed using the viewpoint of the viewer, corresponding portions of the first image and the second image. The system may display the output image in the display region of the monoscopic display.

摘要： In one embodiment, a method includes the steps of capturing an image from a camera viewpoint, the image depicting a physical keyboard, detecting one or more shape features of the physical keyboard depicted in the image by comparing pixels of the image to a predetermined shape template, the predetermined shape template representing visual characteristics of spaces between keyboard keys, accessing predetermined shape features of a keyboard model associated with the physical keyboard, and determining a pose of the physical keyboard based on comparisons between (1) the detected one or more shape features of the physical keyboard and (2) projections of the predetermined shape features of the keyboard model toward the camera viewpoint.

摘要： In one embodiment, a computing system receives one or more signals indicative of light intensities captured by one or more cameras. These signals are captured in a plurality of frames at a first frame rate. The computing system calculates light intensity metrics for each frame of the plurality of frames based on the one or more signals captured in the respective frames. The computing system detects one or more peaks based on the light intensity metrics associated with one or more frames of the plurality of frames. The one or more frames were captured in a predetermined time period. The computing system determines a likelihood of perceptible flicker based on the detected one or more peaks. The computing system generates a notification indicating the likelihood of perceptible flicker in response to a determination that the likelihood of perceptible flicker exceeds a predetermined threshold.

摘要： An eye tracking unit that includes one or more transmitters that transmit a signal (e.g., a radar signal or an ultrasonic sound) at an eye, one or more receivers that receive a reflection of the signal generated by interaction of the signal with the eye, and an eye orientation estimation module that estimates an orientation of the eye based on the reflected signal received by the one or more ultrasonic receivers and based on a model of the eye. The eye tracking unit may be part of a head-mounted display (HMD) that includes a display element configured to display content to a user wearing the HMD. The model of the eye may be trained by displaying a visual indicator on the electronic element and detecting a reflected signal corresponding to the eye looking at the visual indicator.

摘要： Disclosed herein are systems and methods for using microlens arrays for parallel micropatterning of features. A method includes emitting a laser beam providing the laser beam to a lenslet array including a plurality of lenslets, and generating, from the laser beam, a plurality of laser sub-beams using the lenslet array. Each one of the plurality of laser sub-beams is generated by a corresponding one of the plurality of lenslets. Each lenslet of the plurality of lenslets has the same shape.

摘要： An electronic device includes a microphone array configured to capture audio data, one or more sensors configured to detect an orientation of the microphone array, and digital signal processing (DSP) logic, and an interface. The DSP logic processes, based on the orientation of the microphone array detected by the one or more sensors, the audio data captured by the microphone array to form audio input data. The interface configured to transmit the audio input data over a communications channel to be output by another electronic device.

摘要： Disclosed herein are techniques for eye tracking in near-eye display devices. In some embodiments, an illuminator for eye tracking is provided. The illuminator includes a light source configured to be positioned within a field of view of an eye of a user; a first reflector configured to shadow the light source from a field of view of a camera; and a second reflector configured to receive light from the light source that is reflected by the eye of the user, and to direct the light toward the camera.

摘要： Embodiments of the disclosure are directed to index-gradient antireflective coatings that include a differential concentration of nanovoids versus thickness of the coating. In one embodiment, an index-gradient antireflective coating may have an index of refraction that varies from a first value to that of a second material. In another embodiment, the substrate may be optically transparent, and made of, for example, polymer, glass, or ceramics. The index-gradient antireflective coating can be fabricated using a non-uniform spin-coating process, by successive thermal evaporation, or by a chemical vapor deposition (CVD) process. In another embodiment, the spin-coating process can include multiple steps that include different concentrations of monomers to solvent, different spin-speeds, or different annealing times/temperatures. Similarly, the thermal evaporation can include multiple steps that include different concentrations of monomers, initiators, solvents, and associated processing parameters. Various other methods, systems, apparatuses, and materials are also disclosed.
