A multi-viewpoint approach to support collaborative user interface generation

Human-Computer Interaction (HCI) addresses the study, planning and design of the interaction between people and computers through User Interfaces (UIs). The co-design and co-development of these UIs involve different stakeholders as Developers, Functional Analysts, Usability Experts among others, all of them responsible for different UI elements (respectively implementation, functional requirements, usability). Collaboration between stakeholders has been identified as a key factor for UI design and development. This article proposes a multi-viewpoint approach to support collaboration in a UI co-design and co-development process. The article discusses the process itself and the different viewpoints manipulated by all the involved stakeholders. We propose an implementation of our approach in a model-based multi-viewpoint prototype. We show the feasibility of this approach implementing it on a case-study and a multi-viewpoint prototype.
