This group has now closed and its specifications have been republished as Working Group Notes. Discussions on model-based user interface design are expected to continue within the W3C Ubiquitous Application Design Community Group, which was set up with a view to encouraging dialog between developers and researchers.
The mission of the Model-Based UI Working Group, part of the Ubiquitous Web Activity, is to develop standards as a basis for interoperability across authoring tools for context aware user interfaces for Web-based interactive applications.
Application developers face increasing difficulties due to wide variations in device capabilities, in the details of the standards they support, the need to support assistive technologies for accessibility, the demand for richer user interfaces, the suites of programming languages and libraries, and the need to contain costs and meet challenging schedules during the development and maintenance of applications.
Model-based design of user interfaces focuses on separating out different levels of design concerns, allowing designers to focus on what they do best without becoming bogged down due to the complexity of particular delivery contexts. This is especially important given the demands to provide services on an ever increasing range of devices, including support for assistive technology for users with disabilities.
The MBUI Working Group's initial focus is on task models, and UI components and integrity constraints at a level of abstraction independent of the choice of device. Future work is anticipated on taking this to the next level — the concrete UI which involves design choices specific to broad classes of devices. Models at this level can be compiled down for specific delivery channels, guided by author supplied preferences (UI skins). Further out, we hope to address standards for interoperable exchange of rules for dynamic adaptation to the context.
Model-Based UI standards are particularly relevant to creating the user interfaces (service front-ends) for cloud provisioned services, especially custom enterprise services. If your business is a large manufacturing company, or you develop software service solutions for enterprises, we would very much like to hear from you!
The Model-Based UI Working Group has published an updated Working Draft for the MBUI Task Models specification, which enables interchange of high level models of user and system tasks in user interfaces.
Thw Model-Based UI Working Group has published an updated Working Draft for the MBUI Abstract User Interface Models specification, which enables interface of user interface designs at a level independent of particular devices and modes of interaction.
We are pleased to announce that RedHat have volunteered to host the next face to face meeting for the Model-Based User Interfaces Working Group at their facility just outside of Munich. See details.
This specification defines a meta-model and XML serialization for interchange of task models describing the logical activities that have to be carried out in order to reach the user’s goals for interactive systems.
Pisa face to face meeting agenda and minutes, we continue work on specifications for task models and abstract user interface design, as well as the glossary and introduction to model-based UI design.
Kaiserslautern face to face meeting agenda and minutes, we start work on specifications for task models and abstract user interface design, and collecting materials on use cases and business case for model-based UI techniques.
