Abstract: In example implementations, a device is provided. The device includes a microphone, an event generator, a keyword detector, and a digital signal processor. The digital signal processor is in communication with the keyword detector. The microphone is to receive an audio signal. The event generator generates a pattern of events from the audio signal. The keyword detector detects a keyword based on the pattern of events generated by the event generator. In response to the keyword being detected, the digital signal processor is activated to analyze subsequent audio streams.

Abstract: An apparatus includes a support, a first camera, and second camera, and a processor. The support is configured to be mounted to a head of a user. The first camera is mounted on the support and positioned to capture a first image of a face of the user. The second camera is mounted on the support and positioned to capture a second image of the face of the user that is non-overlapping with the first image. The processor is mounted to the support and programmed to stitch the first image and the second image together to construct an image of the face of the user.

Abstract: Audio signal dereverberation can be carried out in accordance instructions on a machine readable storage medium, using a processor. In an example, a location of a person in a room can be determined. An audio signal received from the location of the person can be captured using beamforming. Room properties can be determined based in part on a signal sweep of the room. A dereverberation parameter can be determined based in part on the location of the person and the room properties. The dereverberation parameter can be applied to the audio signal.

Abstract: An example non-transitory computer-readable storage medium comprises instructions that, when executed by a processing resource of a computing device, cause the processing resource to generate haptics metadata using audio-haptics classification based at least in part on spatial audio associated with a digital environment. The instructions further cause the processing resource to encode the spatial audio with the haptics metadata to generate a rendering package.

Abstract: In an example, an augmented reality display system includes a reflective surface, a depth scanner and processing apparatus comprising an image processor and an image generation engine. The depth scanner may be to scan the reflective surface and a subject via the reflective surface to acquire depth data. The image processor may be to determine, based on the depth data, a viewpoint for an augmentation of a reflected image. The image generation engine may be to generate the augmentation for display on the reflective surface.

Abstract: Examples of methods for controlling machine learning model structures are described herein. In some examples, a method includes controlling a machine learning model structure. In some examples, the machine learning model structure may be controlled based on an environmental condition. In some examples, the machine learning model structure may be controlled to control apparatus power consumption associated with a processing load of the machine learning model structure.

Abstract: A communication system may include, in an example, a first computing device communicatively coupled, via a network, to at least a second computing device maintained at a geographically distinct location than the first computing device; the first computing device including: an array of audio output devices and a processor to receive transmitted speech data and metadata describing an estimated direction of arrival (DOA) of speech from a plurality of speakers at an array of microphones at the second computing device and render audio at the array of audio output devices associated with the first computing device by eliminating spatial collision during rendering; said spatial collision arising due to the low angular separation of the estimated DOA of a plurality of speakers.

Abstract: A method, an apparatus and a machine-readable medium are disclosed. The method relates to operating a user interface. The method may include obtaining, using a sensor associated with a first processing apparatus, data indicative of a pose of an control element and a gesture performed by the control element; delivering the data indicative of the pose and the gesture from the first processing apparatus to a second processing apparatus, the second processing apparatus associated with a computing device for displaying a user interface, wherein the second processing apparatus is remote from the first processing apparatus; generating, based on the data indicative of the pose, a representation of the control element to be presented on the user interface; presenting the representation of the control element on the user interface; determining, using the second processing apparatus, an operation corresponding to the performed gesture; and performing the operation in respect of the user interface on the computing device.
