AUTOMATIC LOCALIZATION OF AUDIO DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022869 titled 'AUTOMATIC LOCALIZATION OF AUDIO DEVICES

Simplified Explanation

The abstract describes a method for estimating the position and orientation of smart audio devices in an audio environment based on direction of arrival (DOA) data and configuration parameters. The method involves receiving DOA data from a first smart audio device corresponding to sound emitted by a second smart audio device and received by the first device. It also involves receiving configuration parameters related to the audio environment and the audio devices. A cost function is then minimized using the DOA data and configuration parameters to estimate the position and orientation of the smart audio devices.

  • The method involves receiving DOA data from smart audio devices in an audio environment.
  • Configuration parameters related to the audio environment and audio devices are also received.
  • A cost function is minimized using the DOA data and configuration parameters.
  • The estimated position and orientation of the smart audio devices are obtained.

Potential Applications:

  • Smart home systems: The method can be used to accurately locate and orient smart audio devices in a home environment, enabling better audio distribution and control.
  • Virtual reality/augmented reality: The method can assist in tracking the position and orientation of audio devices used in virtual or augmented reality applications, enhancing the immersive audio experience.
  • Conference rooms: The method can be applied to optimize the placement and alignment of audio devices in conference rooms, improving audio quality during meetings and presentations.

Problems Solved:

  • Accurate device positioning: The method solves the problem of accurately estimating the position and orientation of smart audio devices in an audio environment, which can be challenging due to sound reflections and multipath effects.
  • Configuration optimization: By considering configuration parameters, the method helps optimize the placement and settings of audio devices to achieve optimal audio performance.

Benefits:

  • Improved audio quality: By accurately estimating the position and orientation of smart audio devices, the method enables better audio distribution and localization, resulting in improved audio quality for users.
  • Enhanced user experience: The method enhances the overall user experience by providing more precise audio positioning and immersive sound in various applications.
  • Time and cost savings: The method automates the estimation process, reducing the need for manual calibration and adjustment of audio devices, leading to time and cost savings in installation and setup.


Original Abstract Submitted

a method may involve: receiving direction of arrival (doa) data corresponding to sound emitted by at least a first smart audio device of the audio environment that includes a first audio transmitter and a first audio receiver, the doa data corresponding to sound received by at least a second smart audio device of the audio environment that includes a second audio transmitter and a second audio receiver, the doa data corresponding to sound emitted by at least the second smart audio device and received by at least the first smart audio device; receiving one or more configuration parameters corresponding to the audio environment, to one or more audio devices, or both; and minimizing a cost function based at least in part on the doa data and the configuration parameter(s), to estimate a position and an orientation of at least the first smart audio device and the second smart audio device.
