The research activity in this area is mainly focused on study, design, evaluation, and implementation of interactive computing systems for human use, primarily within the framework of national and international projects that can be methodologically positioned in the so-called 2nd and 3rd paradigms of the Human-Computer Interaction (HCI). The 2nd paradigm is based on the metaphor of “interaction as information communication”, and its primary goal is optimizing the accuracy and the efficiency of information transfer among computers and their users, while the 3rd paradigm is based on the metaphor of “interaction as phenomenologically situated” and refocuses attention from single user / single computer paradigm towards collaboration and communication through physically shared objects. According to the very nature of these areas, research activities of the IDEA group are carried on at both methodological level and application level, within the context of an interdisciplinary approach that calls into question researchers fIrom HCI-related areas as well as from specific project-related application domains. In particular, research lines with a more methodological nature refer to ambient and notification systems, content-based information retrieval, Information Systems and Design Research, computer-mediated communication, while application-oriented research lines fall in the fields of Adaptive Learning Systems, Disaster Management Systems, e-care, Social Networks, Technology Enhanced Learning support systems based on virtual worlds and gamification. Furthermore industrial research is carried on in the field of distributed ambient security applications, including digital video multi source/multi client systems.
