| Abstract(in English) | We have developed parametric loudspeaker drive system with interface to indicate irradiation point of the speaker explicitly on the picture. Calculating irradiation position was used disparity image generated by stereo camera images. As a result of irradiation direction control experiment, it was able to be output beam to indicated direction with an error $pm 1^{circ}$ in azimuth and elevation angle. Also, as a result of evaluation of spot transmission system assumed that audio transmission from several people to a specific person, when beam was focused on subjects, they were able to recognize about 98 % that beam was focused on themselves, and when beam was focused on other than them, the average percentage of correct answers increased as the distance between subjects increased, they were able to recognize about 94 % at 150 cm. The effectiveness of spot transmission system has been confirmed. |
