Overview• Serenoa is aimed at developing a novel, open platform for

enabling the creation of context sensitive service front-ends (SFEs)

• Context-sensitive SFE provides a user interface (UI) that– exhibits some capability to be aware of the context

• User• Platform• Environment

– and to react to changes of this context in a continuous way

• Goal: improving people’s satisfaction and performance compared to traditional SFEs based on manually designed UIs

Task & Domain (T&D)

Reification: from high- to lower-level T&D → AUI AUI → CUI: e.g., a GUI, a vocal UI CUI → FUI: e.g., HTML, VB for GUI

VoiceXML, X+V for Vocal UI

Abstraction: from low- to higher-level FUI → CUI: e.g., reverse HTML CUI → AUI: e.g. for changing modality AUI → T&D: e.g., for recovering task

Reflexion: at the same level FUI: e.g. transcoding CUI: e.g., graceful degradation AUI: e.g., restructuring T&D: e.g., for retasking

Standardization action with W3C• Step 1: W3C Incubator Group on Model-

Based User Interface Design– The Cameleon Reference Framework is a

reference for expressing the levels of abstraction during user interface development

– Recommended in the final report athttp://www.w3.org/2005/Incubator/model-based-ui/XGR-mbui-20100504/ (July 2010)

Standardization action with W3C• Step 2: Serenoa partners join their effort – IDEAL2 (CTIC):

– Maria (ISTI): http://giove.isti.cnr.it/tools/MARIA/home

– UsiXML (UCL): www.usixml.eu, www.usixml.org

Standardization action with W3C• Step 3: W3C Charter Group on Model-Based User

Interface Design (http://www.w3.org/wiki/Model-Based_User_Interfaces)– Also see http://www.w3.org/2011/mbui/– Started Feb. 2012, end in Nov. 2013– Lead by Dave Raggett <dsr@w3.org>

• Contents– Introduction to MBUI– Glossary of MBUI terms– Task meta-model– Abstract user interface meta-model

Task meta-model

Abstract UI meta-model(work in progress)

Next steps• Finalizing the meta-models and interchange

formats– UML2.0 Class Diagram and OWL2 Full ontology– XML Schema

• Coverage of use cases• Software implementation compliant with the

W3C MBUI format• Quill – A Collaborative model-based UI editor

using WebSockets– http://www.w3.org/2012/quill/
