摘要： Technology is disclosed for optimizing a near-eye display using a waveguide. A first waveband for a first color narrower than the full spectral bandwidth for the first color and a second waveband for a second color adjacent to the first color in the visible spectrum are generated in image light of an image generation unit like a microdisplay. The first waveband and the second waveband are coupled into a same layer of a diffractive waveguide. An input grating of the same layer of the waveguide has a grating wavelength band approximately matching a waveband extensive with the first waveband and the second waveband. A converted green light emitting diode (LED) may be used for obtaining a first waveband centered around 515nm in some examples. One of more of the wavebands may be obtained using filters, for example filters using dichroic mirrors, quantum dots or a combination of these.

摘要： Technology is described for reducing display update time for a near-eye display (NED) device. A point of focus in the NED field of view is identified, often based on natural user input data. A communication module of a computer system communicatively coupled to the NED device transmits lossless priority data, an example of which is user focal region image data, using one or more communication techniques for satisfying lossless transmission criteria. Allowed loss image data is identified based at least in part on its distance vector from a point of focus in the display field of view. An example of allowed loss image data is image data to be displayed outside the user focal region. The allowed loss image data is transmitted and extracted from received image data allowing for lossy transmission.

摘要： Light guide techniques are described. In one or more implementations, an apparatus includes a housing, a light guide supported by the housing, a light engine disposed within the housing and optically coupled to the light guide, and one or more modules disposed within the housing and implemented at least partially in hardware. The one or more modules are configured to cause the light engine to output a user interface for display using the light guide along an image plane focused at infinity.

摘要： Various technologies are applied to focus audio received from a plurality of microphones of a mobile device. A camera can be used to portray a scene, and a selection within the scene can focus audio to a desired audio focus region. Techniques can account for movement of the mobile device or an object being tracked. Pre-computed audio filters can be used to customize the audio focus process to account for a particular mobile device geometry.

摘要： A system and method are disclosed for determining a depth map using TOF with low power consumption. In order to disambiguate, or de-alias, the returned distance(s) for a given phase shift, the system may emit n different frequencies of light over n successive image frames. After n frames of data are collected, the distances may be correlated by a variety of methodologies to determine a single distance to the object as measured over n image frames. As one frequency may be emitted per image frame, the depth map may be developed while consuming low power.

摘要： Examples of the disclosure describe user environment aware single channel acoustic noise reduction. A noisy signal received by a computing device is transformed and feature vectors of the received noisy signal are determined. The computing device accesses classification data corresponding to a plurality of user environments. The classification data for each user environment has associated therewith a noise model. A comparison is performed between the determined feature vectors and the accessed classification data to identify a current user environment. A noise level, a speech level, and a speech presence probability from the transformed noisy signal are estimated and the noise signal is reduced based on the estimates. The resulting signal is outputted as an enhanced signal with a reduced or eliminated noise signal.
