“…We have succeeded in reproducing a sound field using a multipole-loudspeaker array consisting of multiple small speakers closely arranged in a Cartesian grid. This array enables control of the directivity pattern of an arbitrary sound source while being smaller than current speaker arrays [9,10]. These technologies place importance on achieving natural communications to enable users to enjoy a sense of reality without having to wear special devices such as head mounted displays, 3D glasses, or headphones.…”

NTT Service Evolution Laboratories is conducting research on providing high-presence viewing experiences involving virtual people and objects as if they have been brought to life right in front of the viewers. This article introduces natural communication technologies providing natural and valuable user experiences by creating people, objects, and space that emulate an incredibly realistic presence and seamlessly linking them to the real world through natural interactions without any sense of latency.
