    Abstract: An augmented reality environment allows interaction between virtual and real objects. Multiple microphone arrays of different physical sizes are used to acquire signals for spatial tracking of one or more sound sources within the environment. A first array with a larger size may be used to track an object beyond a threshold distance, while a second array having a size smaller than the first may be used to track the object up to the threshold distance. By selecting different sized arrays, accuracy of the spatial location is improved.

    Abstract: An architecture for selecting and providing content items to a device includes cloud-based resources of a device management service and one or more content sources. The device is configured to receive instructions and a portion of the content item from the device management service. The instructions direct the device to obtain and buffer the content item from the content source, while simultaneously outputting the portion of the content item to a user.

    Abstract: The systems, devices, and processes described herein may asynchronously transfer audio signals from a voice-controlled device to a remote device. The audio signals may correspond to sound that is captured by multiple microphones of the voice-controlled device, which may then process the audio signals. The audio signals may also be transferred to the remote device for processing. Moreover, a determination of whether the voice-controlled device or the remote device is to process the audio signals may be based at least in part on the bandwidth of a network communicatively coupled to the voice-controlled device. The voice-controlled device may also cache and log the audio signals, and then asynchronously stream the audio signals to the remote device after the audio signals are initially processed, which may be based on the bandwidth of the network. The remote device may utilize the unprocessed audio signals to improve subsequent processing of audio signals.

    Abstract: An architecture includes a system to create an augmented reality environment in which images are projected onto a scene and user movement within the scene is captured. The augmented reality environment is hosted within a surrounding area in which various ambient conditions, external to the augmented reality environment, persist. The architecture monitors the external conditions and controls secondary devices that selectively modify the conditions as desired in cooperation with operation of the augmented reality environment to effectively enhance user experience. Alternatively or additionally, the architecture may inform the user of what changes to make, and the user manually makes the adjustments.

    Abstract: A two-dimensional (2D) image and a three-dimensional (3D) of an environment may be captured. Upon identifying a location and/or contour of an object from the 3D image, the object from the 3D image may be mapped onto the 2D image. The object, including its location and contour, may be identified from the 2D image. Based at least partly on a comparison between the object from the 3D image and the object from the 2D image, a disparity may be calculated. The location and contour of the object may be determined when it is determined that the disparity is less than or equal to a predetermined threshold. Otherwise, the object from the 3D image may be remapped onto the 2D image.
