1 DEIM Forum 2010 D Development of a Large-scale Visualization System Based on Sensor Network Abstract Takashi NAKANE, Masaaki EDA, Shohei YOKOYAMA, Naoki FUKUTA, and Hiroshi ISHIKAWA Department of Computer Science, Faculty of Informatics, Shizuoka University Johoku 4-5-6, Nakaku, Hamamatsu-shi, Shizuoka, Japan {cs06062,cs06015}@s.inf.shizuoka.ac.jp, {yokoyama,fukuta,ishikawa}@.inf.shizuoka.ac.jp Recently, it is said to connect with the power saving by making power consumption at home etc. visible. In the resaerch, the visualization system to tie to the power saving or more is developed by making not only power consumption but also the man action visible, and making uselessness easy to discover by using the sensor network. Moreover, the visualization system,for example when sensor network in building visualized,not only browsing sensing data with other floor but also browsing all floor at a time,and to aim at a large-scale visualization system by which the person can look down upon the entire Sensing data Key words Visualization Sensing Data 1.
