I believe that the current interaction design field is built on the foundation of Web 2.0. Because static web pages dominated the first stage of the development of the Internet, people did not have too much “interaction” on it, and people did not have the awareness of “interaction” with the Internet or web pages. In the era of Web 2.0, more attention was paid to user-driven, people began to notice the importance of interaction between people and dynamic pages, and more emphasis was placed on collaboration and sharing user content. So people are no longer simply acquiring information and constantly creating information at the same time.
