We investigate conceptual models and architectures for the representation and integration of information across media boundaries. It is time to question existing document formats which are very much based on the simulation of paper on static desktop computers and to come up with innovative information concepts for the representation of open and fluid cross-media "documents".

Nowadays, the so-called Internet of Things (IoT) and Web of Things (WoT) start to play a more important role in our daily lives, given that many appliances are connected to the Internet. Solutions such as the popular If This Then That (IFTTT) enable users to define rules for implicit interactions with their IoT-enabled devices. However, existing IoT solutions do not support human-computer interactions across platform boundaries and we therefore investigate the necessary concepts and architecture for a cross-platform IoT middleware.

Context-aware applications are applications that take into account a user's context (e.g. personal preferences, characteristics, agenda) and environment (e.g. people, places and things in the user's vicinity), in order to provide an improved user experience.
