Interacting with Ambient Intelligence

Interactive systems have been the dominant computing paradigm over recent years. This paradigm is characterized by the fact that human user and the system communicate and interact explicitly using different modalities. However to come closer to visions of Ambient Intelligence, Calm Computing, Disappearing Computing, and Ubiquitous Computing new forms of interaction are required. Observing humans interacting with each other and new possibilities given by emerging technologies indicate that a new interaction model is needed. In this chapter we present the concept of implicit human computer interaction (iHCI) that takes the users context into account when creating new user interfaces for ambient intelligence. Beyond the model examples are given, application areas are described and basic implementation issues are discussed. Our research leads to a more general discussion on disappearing and invisible user interfaces. In the invisibility dilemma we explain that in many application areas there may be an inherent conflict. The transparent user interface and the added value gained by introducing technology are often opposing goals, especially combined with users that are creative in appropriating their tools.
