1. An information processing device, comprising:
processing circuitry configured to:
estimate a first attribute of a first person located in at least one of a plurality of areas,
measure a first location or a movement of the first person,
estimate a second location of the first person after a predetermined time based on the first location or the movement of the first person,
set a first content corresponding to the first attribute of the first person and output a first sound through wave field synthesis so that a first sound field of the first content is spatially transmitted to the second location of the first person after the predetermined time via a plurality of speakers,
estimate a second attribute of a second person in another area of the plurality of areas and set a second content corresponding to the second attribute of the second person,
output a second sound through wave field synthesis so that a second sound field of the second content is spatially transmitted to the another area via the plurality of speakers, and
when the first person and the second person are in a same area of the plurality of areas, prioritize transmission of one of the first content and the second content to the same area and output one sound of the first sound and the second sound according to a predetermined order of priority of the first content and the second content so that a sound field of the one of the first content and the second content is spatially transmitted to the same area,
wherein a first virtual position of a first virtual sound source of the first sound is set based on a location of the first person and the movement of the first person and
a second virtual position of a second virtual sound source of the second sound is set based on a location of the second person.
