A multidimensional classification model for the interaction in reactive media rooms

We are already living in a world where we are surrounded by intelligent devices which support us to plan, organize, and perform our daily life. Their number is constantly increasing. At the same time, the complexity of the environment and the number of intelligent devices must not distract the user from his original tasks. Therefore a primary goal is to reduce the user's mental workload. With the emergence of newly available technology, the challenge to maintain control increases, while the additional value decreases. After taking a closer look at enriched environments, there will come up the question of how to build a more intuitive way for people to interact with such an environment. As a result the design of proper interaction models appears to be crucial for AmI systems. To facilitate the design of proper interaction models we are introducing a multidimensional classification model for the interaction in reactive media rooms. It describes the various dimensions of interaction and outlines the design space for the creation of interaction models. By doing so, the proposed work can also be used as a meta-model for interaction design.
