Abstract
Acoustic vector data is sensed via acoustic vector sensor configurations in mobile devices and used to generate sound fields. From these sound fields, positioning and orientation of the mobile device is derived. The sound fields and features derived from them are classified to provide mobile device position and other information about the environment from which the sound fields are captured. Additionally, sound fields are analyzed to detect gestural input and trigger associated programmatic actions.
