The division of roles becomes more and more complex in user interface development, and the tools used in the development process vary greatly. These problems result in increase of communication cost and decrease of efficiency. This article introduces a development method based on user interface description language. First, a new user interface description language E-UIDL is proposed. Then, a series of supporting tools based on E-UIDL are designed. Next, the development process of the user interface based on E-UIDL and related tools is presented. Finally, the feasibility of the proposed method is validated.
