We have one project about cyber-physical systems. One of the important topics in
researches on cyber-physical systems is the analysis of big data to be collected from
the physical world. As one of the analysis methods, information visualization is use-
ful. Currently, we have been developing two types of visualization tools using
Intelli-
gentBox
system for our cyber-physical system project. The first one is for the analysis
of human movements because human movements are very important cues for the
analysis of human activities. The left figure of Figure 8 shows a screen image of such
web content. This is the building of our graduate school consisting of several floors.
To simplify a 3D model for the building, we employ 2D floor map images and use the
texture mapping mechanism. It is very easy to visualize the building and display hu-
man movements. In this case, glyphs have a different color, a different size and a
different shape to specify several attribute values of their corresponding persons and
move on a floor. So, we can understand persons' activities from glyphs' movements.
