In this context, "information design" becomes our subject. And in the era of "multimedia revolution", this subject is practically "multimedia information design." We expect a breakthrough in mathematics education by means of the new media power.

Practically, those who can read a text are those who posess a similar image to the one that the writer of the text tried to represent in the form of text. Developping an image from a text is a blind jump. (Descripting my coffee cup by means of letters will be a hard work, and I cannot expect others to imaginate a similar coffee cup.)

Here comes the "multimedia. " If images can be presented in the form of image (for example, by means of the virtual 3D), it is the best.

Thus, I made it one of my projects to design mathematical subjects (primarily, in elementary school mathematics) in the form of visual image, by means of multimedia.
