Abstract: PROBLEM TO BE SOLVED: To provide a method and system for detecting a position of a user of a home television game machine. SOLUTION: A speaker 506 mounted in a remote controller is used to reproduce a signal of a predetermined reproduced sound, the reproduced sound is observed respectively by two microphones properly provided in the vicinity of a television screen, CSP (while mutual correlation) coefficients of a signal of an observation sound respectively observed and the signal of the reproduced sound are calculated, and distances between the speaker inside the remote controller and the microphones are calculated, thereby acquiring longitudinal and lateral absolute positions of the remote controller with respect to a microphone array. An interference sound of an environmental sound or noise is canceled by the correlation calculation. COPYRIGHT: (C)2010,JPO&INPIT
