Responsive environments: User experiences for ambient intelligence

In this paper we review the emerging field of responsive environments as an ambient intelligence system with a focus on user experience. We see responsive environments as a combination between the scientific developments that resulted in Ambient Intelligence systems and the aesthetic motivation behind interactive art installations. This next development in Information and Communication Technologies transcends the computer screen and the localised interface towards ambient accessibility and experience. Inspired by different authors in the field of Ambient Intelligence, we redefine Responsive envi- ronments as physical spaces, such as city squares, public halls, etc, that are enhanced with the use of technology and media. The concept of responsive environments is defined in relation to ambient intelligence highlighting system-centred approach based on which it has been developed, and user-centred approach that we believe is the direction to follow. The infrastructure and technology required, notably the necessary sensors and actuators are reviewed in later sections. The user interaction is analysed with a series of examples. The different approaches to the interfaces are contributing to a better understanding of the challenges of selecting the right interaction principle. Furthermore, context awareness and user experience have an important contribution to the success of a responsive environment. An environment where the aesthetic of interaction, user engagement, access, embodiment and intimacy are also to be taken into account in the design and specifications phases.
