1 1. MIERUKEN 1 2 MIERUKEN MIERUKEN MIERUKEN: Speech Visualization System Based on Augmented Reality Yuichiro Nagano 1 and Takashi Yoshino 2 As the spread of the Augmented Reality(AR) technology and service, we are getting at sharing and visualizing various information on real environment. In this study, we focus on speech that used to transmission of information on daily life. We think that speech visualization can support various situations in daily activities. We have developed speech visualization system MIERUKEN based on AR. In this paper, we present the result of a trial experiment and discuss the evaluation of three methods for visualized speech. 1 Graduate School of Systems Engineering, Wakayama University 2 Faculty of Systems Engineering, Wakayama University ARToolKit PTAM Augmented RealityAR 1),2) 1 ARis 2 Web GPSHMD AR AR AR 3) AR AR MIERUKEN MIERUKEN 3 AR ),5) Levin 1 : 2 ARis: 1 c 2009 Information Processing Society of Japan
