  1. Towards a Model-Based Framework for the Development of Adaptive Multimodal User Interfaces for Ambient Assisted Living Environments Marco Blumendorf and Sahin Albayrak DAI-LaborFakultät IV – Elektrotechnik und InformatikTechnische Universität Berlin

  2. Agenda • Motivation • A Runtime Architecture for Adaptive Multimodal User Interfaces • User Interface Models • The Multi Access Service Platform • Conclusion HCI International 2009

  3. Ambient Assisted Living Environments are Smart Environments and reflect Ubiquitous Computing Paradigms HCI International 2009

  4. “Ubiquitous Computing” (Mark Weiser, 1991) “In the 21st century the technology revolution will move into the everyday, the small and the invisible.” HCI International 2009

  5. Smart Objects Smart Devices Smart Networks Smart Environments HCI International 2009

  6. Interaction in Smart Environments used interaction modalities HCI International 2009

  7. Challenges • Complex, distributed system to interact with • Different capabilities and skills of users • Personalization of UIs • Context adaptivity • Continuous, flexible and coherent interaction • Excellent interaction experience • Lack of development tools, methodologies and runtime support HCI International 2009

  8. Agenda • Motivation • A Runtime Architecture for Adaptive Multimodal User Interfaces • User Interface Models • The Multi Access Service Platform • Conclusion HCI International 2009

  9. Requirements • Connect interaction resources • Integrate context • Host the applications • Support UI features(Multimodality, Distribution, Adaptation, …) HCI International 2009

  21. Abstraction Layers See also Szekely 1996, Cameleon Reference Framework (Calvary et al. 2003) Similar concepts can be found e.g. in UsiXML (Limbourg et al. 2004) and TERESA (Berti et al. 2004) HCI International 2009

  22. Mediation Process See also Szekely 1996, Cameleon Reference Framework (Calvary et al. 2003) Similar concepts can be found e.g. in UsiXML (Limbourg et al. 2004) and TERESA (Berti et al. 2004) HCI International 2009

  23. Adding State and Execution Logic • Definition Elements- static structure and constant elements • Situation Elements - state of the model and changing elements • Execution Elements - interpretation process altering state (and definition) at runtime Dynamic Executable Model See e.g. Breton & Bézivin 2001 for details HCI International 2009

  24. Adding State and Execution Logic HCI International 2009

  25. Agenda • Motivation • A Runtime Architecture for Adaptive Multimodal User Interfaces • User Interface Models • The Multi Access Service Platform • Conclusion HCI International 2009

  26. Implementation The Multi-Access Service Platform (MASP) implements the presented concepts Features • Multimodal interaction • Dynamic distribution • Adaptation Different applications have been implemented. HCI International 2009

  27. A Meta UI for Smart Environments HCI International 2009

  28. The Multimodal Cooking Assistant HCI International 2009

  29. Agenda • Motivation • A Runtime Architecture for Adaptive Multimodal User Interfaces • User Interface Models • The Multi Access Service Platform • Conclusion HCI International 2009

  30. Results • We can build models of multimodal applications that dynamically change the used modalities. • Applications can be distributed and dynamically configured at runtime. • A follow me mode shows automatic reconfiguration based on context information. • Dynamic layout changes according to the distance of the user to the screen have been realized. HCI International 2009

  31. Open issues and future work • Technology and software engineering centric • Next Step: Study how to deploy the features properly to provide integration into environment and the required excellent user experience! • Additional Aspects: • multi-user and multi-application scenarios have not been adequately addressed yet • tools also covering runtime issues and moving towards end-user development and customization • integration of natural language processing and models-based development HCI International 2009
