Human Choice and Computers: Issues of Choice and Quality of Life in the Information Society presents different views about how terrorist actions are influencing political and social discussions and decisions, and it covers questions related to legitimacy and power in the Information Society. Ethical principles are important guidelines for responsible behavior of IT professionals. But even under strong external pressure, long ranging aspects such as education and the roles of developing countries in the Information Society are important to discuss, especially to enable all to actively participate in information processes.

This book integrates a wide range of research topics related to and necessary for the development of proactive, smart, computers in the human interaction loop, including the development of audio-visual perceptual components for such environments; the design, implementation and analysis of novel proactive perceptive services supporting humans; the development of software architectures, ontologies and tools necessary for building such environments and services, as well as approaches for the evaluation of such technologies and services. The book is based on a major European Integrated Project, CHLI (Computers in the Human Interaction Loop), and throws light on the paradigm shift in the area of HCI that rather than humans interactive directly with machines, computers should observe and understand human interaction, and support humans during their work and interaction in an implicit and proactive manner.

This book constitutes the refereed proceedings of the 15th IFIP TC 9 International Conference on Human Choice and Computers, HCC15 2022, in Tokyo, Japan, in September 2022. The 17 full papers presented were carefully reviewed and selected from 32 submissions. Summaries of 2 keynote presentations are also included. The papers deal with the constantly evolving intimate relationship between humans and technology.

INTERACT 2009 was the 12th of a series of INTERACT international c- ferences supported by the IFIP Technical Committee 13 on Human–Computer Interaction. This year,INTERACT washeld in Uppsala (Sweden), organizedby the Swedish Interdisciplinary Interest Group for Human–Computer Interaction (STIMDI) in cooperation with the Department of Information Technology at Uppsala University. Like its predecessors, INTERACT 2009 highlighted, both to the academic and to the industrial world, the importance of the human–computer interaction (HCI) area and its most recent breakthroughs on current applications. Both - perienced HCI researchers and professionals, as well as newcomers to the HCI ?eld, interested in designing or evaluating interactive software, developing new interaction technologies, or investigating overarching theories of HCI, found in INTERACT 2009 a great forum for communication with people of similar int- ests, to encourage collaboration and to learn. INTERACT 2009 had Research and Practice as its special theme. The r- son we selected this theme is that the research within the ?eld has drifted away from the practicalapplicability of its results and that the HCI practice has come to disregard the knowledge and development within the academic community.

The principal message of the ‘Human Choice and Computers’ (HCC) tradition and its associated conferences over the years is that there are choices and alternatives. In this volume, Social Informatics takes two directions. The first supports readers in interpreting of the meaning of Social Informatics. The second, more extensive part develops an overview of various applications of Social Informatics. Researchers inspired by Social Informatics touch many areas of human and social life.

Focuses on systems that help people choose for themselves. Realizing this potential requires an understanding of how people make everyday choices and the design strategies and computing technologies that can be used to support these processes. This work offers a compact synthesis of research on these topics.
