If a content creator that creates content and a service provider that provides the content are different, the content should be reconfigured and provided. In order to provide an interface suitable for a user environment, only a limited user environment should be considered. Thus, flexibility is low when an adaptive user interface is provided. It is possible to provide a user interface, independently of the relevant designer, by redefining content, a usage environment, and a relation between a page and a service provider and dynamically providing a user interface suitable for the user environment.
