Abstract:We propose a real-time indoor dynamic acoustic field generation system of a spot audio towards a particular person.
Many audio interaction systems that are appearing in mobile interactions and personal recognition by audio recognition techniques are nowadays increasing its accuracy. In these fields, continuous sound propagation for individuals is highly desired. However, sound waves have low directivity thus widely received by unintentional hearers. To solve this problem, continuous efforts have been made, such as audible-sound directions loudspeakers and ultrasound-based super directional loudspeakers.
