5. Gent, 21 maart 2005 Context-Aware User Interfaces Distributable user interfaces  Distributing parts of a user interface over “appropriate” available devices

6. Gent, 21 maart 2005 Context-Aware User Interfaces Examples: context-aware rendering of downloaded user interface models  Instant Messaging application Downloading the models to Desktop computer, TV, PDA, smart phone  Render the interface adapted to context  Museum visit: Abstract user interface models stored at the artifact's information services are pushed to client devices when necessary  Render the interface adapted to context
