Narrowcasting visualization using particles for spatial sound conferencing

The goal of this study is to visualize duplex auditory communication filtered with narrowcasting. Narrowcasting is technology that enables media stream filtering for privacy. Audio narrowcasting has four operations (solo & mute and attend & deafen). In this research, communication from source to sink is determined according to these four operations, including “autofocus” determination of multipresent sinks, and visualized using flying particles. Soundscapes are compiled according to narrowcasting attributes. With such multimodal representation, users can more easily understand narrowcasting communication.
