The Priority Programme further implements two obligatory mechanisms to ensure the cohesion and cross-fertilisation among projects: (a) reference scenarios and (b) tandem projects. (c) One of the following three reference scenarios should be addressed within the proposals:

Personal smart spaces

• A personal home space is characterised by being familiar to the individual and family and friends, but only rarely including strangers. It is a space shared by different people live together and using the available interaction paradigms. Several typical interactive devices may be found in this home, including those designed for entertainment, devices brought to the home by visitors, as well as devices for interaction with the home as a smart space. This space contains less “noise” than a public smart space; rather it is characterised by privacy and intimacy.

Public smart spaces

• A public smart space is characterised as a space typically unfamiliar to the individual. We find multiple interactive displays, cameras, sensors and actuator technologies in a larger area, perhaps several meters, so thata t least some of the interactive technologies are unreachable. A public smart space is a space in which multiple persons can be present who are strangers to each other. The space can be either indoors or outdoors and may involve contextual “noise” such as acoustic noise, lighting conditions, temperature, or the weather.

Smart control rooms

• Control spaces are characterized by ensembles of devices of varying functions that are jointly contributing to a professional and potentially safety-critical task. While each of the devices has an individual interface, meaning, and interaction, the individual interacting in this space is contributing to a common goal.
