The Web has taken a strong post as one of the media for advertisement for long time. The Internet has an advantage of an easy access to each of customers; the fractioning of the potential customers; the transcending of the time and space; and the utilizing of the multimedia. As such, the Web as a communication tool has not only all characteristics of the existing media but also the factors such as the sound, motion, and interaction. Therefore the Web designing should be much more flexible and open than any other medias. Nevertheless, most of the Webs being created currently appear to be simply perfunctory and functional. This is because a methodological aspect has not been rooted firmly as the Web design industry has been developed too rapidly, driven by the explosive demand. Therefore, this study is designed to demonstrate the approaching method to the Web-interface designing as an alternative for such methodological aspect. In other words, it is the very stillness-motion interface designing of the Web, based on the e-advertisement concept. The Web as one of the media for advertisement gives the heaviest weight to the users emotional aspects than any other media do. Therefore, it is very important to get the differentiation and impact in the Web-interface designing through the users emotional aspects.
