Abstract

The ICT (Information and Communication Technologies) infrastructure has been tremendously changed during the last couple of decades and the result made a big change in the computing environment. Due to this drastic advance, now we are enjoying a convenient living environment that we couldn’t have ever experienced before. In addition to this situation, the prospective emerging technologies such as the cloud computing and the mobile computing are newly approached and trying to realize a new life infrastructure combined with so-called a whole-cyber complex that is becoming fully connected and proportional to our real world. These results of this evolutionary transformation are part of essential components of the world with the augmented three dimensional common user interface to a single unified cyber-physical space.
