Context Modeling

Chair: Joelle Courtaz

Although context is recognized as a first class concept in ubiquitous computing, there is no clear working definition that could lead to a sound computational model for the development of context-sensitive systems.

Firstly, the group discussed a number of issues and notions related to that of context: What is a situation? How does it relate to a task and a context? Is there a need for revisiting task modelling as well as its role in the design process?

Secondly, the group looked into a taxonomy of context widgets (or contextors) based on A. Dey's and J. Coutaz's work, including aggregators and abstractors (interpreter).

See the summary slides of the context modeling group.
