Model-driven development of user interfaces: Promises and challenges

In this paper we discuss promises and challenges of model-driven development of user interfaces. MDD's defining characteristic is that development's primary focus and products are models rather than computer programs. These aspects are very important for HCI, as user interface development is complex, multidisciplinary activity, while the implementation platforms do not directly support many of important high-level HCI concepts. Joining MDD and HCI can bring many advantages to both fields. In the case of HCI, it would enable more efficient development of user interfaces, usage of existing standards, tools, and wider acceptance of these results. On the other hand, integrating human-computer interaction accomplishments into the MDD approach can lead toward creation of more complete and better accessible solutions. Still, there are many open problems. One of the main challenges is the absence of the formal description of relevant HCI concepts, which in MDD should serve as the metamodel.
