A visual tool for user-interface development

VITUID is a visual tool for user interface development. It aims to help user-interface designers, who may be non-programmers, to specify and create interactive, graphical user interfaces through graphical interaction. VITUID lets designers specify the user command set and the human-computer dialogs by building a tree and specifying the behavior of each dialog via a dialog-control word, adopting the object-oriented approach. The main strategy of VITUID is to separate a user interface into an application-dependent part and an application-independent part and then let the designer specify only the application-dependent part.
