Abstract (in Japanese) (See Japanese page) 
(in English) We develop an MR system that merged the real and virtual worlds in both the audio and visual sense. In this study, we suggested the method to realize the moving sound image when using "Acoustic Planetarium" as an audio presentation. This method is to interpolate the sound image position between multiple sound images on reflecting points which located by parametric loudspeakers, and showing the sight information at the sound image position. The sound image position interpolation processing was implemented based on conventional methods used for dynamic loudspeakers. And, we had subjective evaluation experiments to confirm whether it is effective even in the case of using the parametric loudspeakers. This paper presents the results and consideration of these experiments.
