Smart Loudspeaker Arrays for Self-Coordination and User Tracking

Abstract

The Internet of Things paradigm aims at developing new services through the interconnection of sensing and actuating devices. In this work, we demon-strate what can be achieved through the interaction between multiple sound devices arbitrarily deployed in space but connected through a unified net-work. In particular, we introduce techniques to realize a smart sound array through simultaneous synchronization and layout coordination of multiple sound devices. As a promising application of the smart sound array, we show that acoustic tracking of a user-location is possible by analyzing scat-tering waves induced from the exchange of acoustic signals between multiple sound objects.
