User Interfaces for Smart Environments

User Interfaces for Smart Environments
• High heterogeneity and dynamics:– Interaction devices are unknown at design time– Users are unknown– Environment is unknown
• Requirements:– Personalization – Adaptation– End-User Development

Roles of run-time UI models
1. Make the design rationale available at runtime2. Provide an abstract view on the UI and its state at
runtime3. Provide means of influencing the UI at runtime

Some open issues
• How can we distinct runtime and design time information in runtime UI models?
• How can the runtime information flow into the models so they are up-to-date at runtime?
• What does a UI language contain if a ubiquitous UI has no fixed size, no fixed interaction device, no fixed user and is not executed in a fixed context?
• What parts of models can be adapted automatically at runtime?
• How can we evaluate the usability of the adapted applications?

Model to System Connection at Runtime
• Common in large, (self-) adaptive systems• Staikopoulos et al., Mutual dynamic adaptation of models and service
enactment in alive*, 2008:– Adaptations performed on the running system via transformations of
the system model• Kuhn and Verwaest, Fame, a polyglot library for meta-modeling at
runtime, 2008– FAME (Polyglot Library)– Adaptation of software at runtime through modifications of models
and meta-models

System to Model Connection at Runtime
• Many approaches based on state charts and stateful model elements• Monitoring state machines enables debugging and tracing of
occurrences in the system on model level• Maoz, Model-Based Traces, 2008
– Model is updated at runtime via traces• Graf and Müller-Glaser, Gaining insight into executable models during
runtime: Architecture and mappings, 2007– Driver Layer between the model and the system with a set of operations– Inspecting and debugging model-based embedded systems at runtime

Model-System Cycle at Runtime
• Cycle between the model and the system– Models reflect the state of the system– The system reacts to changes in the model
• Blair et al., [email protected], 2009:– [email protected] is a causally connected self-
representation of the associated system
