51 Using Multiple Perspectives to Model the User in Ambient Intelligence

According to the decentralization of modeling tasks caused by user who is essentially nondeterministic and highly individual in Ambient Intelligence (AmI) environment, an interactive model based on multi-agent is firstly introduced to abstract the interaction between user and AmI environment. Secondly, the user is characterized by a mental model, a plan model, and a behavior model, which cooperatively describes both the static features and the dynamic behavior, and formal methods to describe these models are discussed at detail. Finally, the path which maps a natural scenario into a real system shows the benefits of using these models to design and develop AmI systems.
