A context visualization model for wearable computers

Context-aware systems observe the user´s current context and apply this information to the user´s benefit. When implementing context-awareness, several issues need to be considered and this paper concentrates on presenting the context information to the user. The key components needed to construct the context are identified, and a model, which allows using different visualization techniques for the context, is proposed. In order to make the model more concrete, four use cases are presented, and the expandability of the model is discussed.
