Abstract: In an information network, an interactive display allows a user to choose products or elements on one screen axis (Y) and compare their characteristics or attributes on a second screen axis (X), thereby aiding a user to select a product from all available information according to the user's individual requirements. The information network includes at least one knowledge site containing product information for access by a user through a terminal. The terminal includes a processor coupled to an interactive display and a storage disk. The processor includes a Java operating system; an application program for processing product information by categories in terms of elements and attributes, and a browser enabling a user to access and interact with the knowledge site through Java applets. The disk contains product information by category received from the knowledge site and transformed into the form of HTML parameters within HTML files.
