In recent years, we often see e-catalogs instead of paper catalogs. A typical e-catalog is only changed just an electronic file of a paper catalog. But depending on the design, this catalog seems that various things can be done. For example, when user looks e-catalog, Our e-catalog system obtains user gaze information, analyses the favorite designs of the user and presents the products that he/she prefers at turning each page. According to that can provide an original catalog for each user. An overview of this system is shown in the figure below.


As a prototype of such a system, we are constructing an interactive evolutionary computation system based on running shoes. As shown in the figure below, the interface that presents the design is an image of a catalog, and this catalog uses interfaces of various design arrangements.


This system uses the user’s gaze information for design evaluation.Because of based on the catalog, this system targets at only a single user.

In addition, as introduced in the Analysis of Human Kansei Evaluation, users have a wide range of tastes. We consider this item in the e-catalog system, and devise of an evolutionary computation for multimodal retrieving.
