1. An information processing system comprising: a recognizing unit configured to recognize a given target on the basis of signals detected by a plurality of sensors arranged around a specific user; an identifying unit configured to identify the given target recognized by the recognizing unit; an estimating unit configured to estimate a position of the specific user in accordance with the a signal detected by any one of the plurality of sensors; and a signal processing unit configured to process signals acquired from sensors around the given target identified by the identifying unit in a manner that, when output from a plurality of actuators arranged around the specific user, the signals are localized near the position of the specific user estimated by the estimating unit.
