Abstract: The present disclosure relates to routers and quality of service (QoS) systems and methods that base decisions on the identification of one or more users of computing devices within the environment. Profiles and/or attributes associated with the users may be created and dynamically updated to optimize user experience. For example, the routers may dynamically adapt QoS settings to regulate bandwidth, latency and other parameters to prioritize users and/or optimize a specific user's experience based on the user's priority, personal profile, and/or other attributes.

Abstract: A system may utilize sound localization techniques, such as time-difference-of-arrival techniques, to estimate an audio-based sound source position from which a sound originates. An optical image or depth map of an area containing the sound source location may then captured and analyzed to detect an object that is known or expected to have produced the sound. The position of the object may also be determined based on the analysis of the optical image or depth map. The position of the sound source may then be determined based at least in part on the position of the detected object or on a combination of the audio-based sound source position and the determined position of the object.
