The IFIP Advances in Information and Communication Technology series is a publication that covers various aspects of information and communication technology. The series is edited by A. Joe Turner and includes contributions from a wide range of experts in the field. The series includes a variety of topics such as computer science, software engineering, education, information technology applications, communication systems, system modeling and optimization, information systems, and the relationship between computers and society. IFIP, the International Federation for Information Processing, was founded in 1960 under the auspices of UNESCO. It is a non-profit organization that supports information processing within its member countries and encourages technology transfer to developing nations. IFIP operates through a number of technical committees, which organize events and publications. The most important events are the IFIP World Computer Congress, open conferences, and working conferences. The IFIP World Computer Congress is the flagship event of IFIP, where both invited and contributed papers are presented. Contributed papers are rigorously refereed and the rejection rate is high. The congress received 642 papers for the 17 conferences, and selected 319 from those, representing an acceptance rate of 49.69% (averaged over all conferences). The congress was hosted by the Australian Computer Society, ACS. It was run as a federation of co-located conferences offered by the different IFIP technical committees, working groups and special interest groups, under the coordination of the International Program Committee. The conference included 17 parallel conferences, focusing on topics ranging from artificial intelligence to entertainment computing, human choice and computers, security, networks of the future and theoretical computer science. The conference History of Computing was a valuable contribution to IFIP's 50th anniversary, as it specifically addressed IT developments during those years. The conference e-Health was organized jointly with the International Medical Informatics Association (IMIA), which evolved from IFIP Technical Committee TC-4 "Medical Informatics". The symposium on Human–Computer Interaction was held as part of the IFIP World Computer Congress 2010. The symposium received 56 contributions, 19 submission were accepted as long presentations and 7 as short ones. Additionally, five submissions were accepted as poster presentations. The selection was carried out carefully by the International Program Committee. The result is a set of interesting and stimulating papers that address such important issues as specification and modeling, user-centered development, usable systems, social and cultural problems, mobile and Web applications and interaction. The interest shown in the conference was truly world-wide: if we consider both full and short papers, we had authors from Europe, South America, Canada, Japan, Singapore, and South Africa. The final program of the symposium included one technical invited speaker: Penelope Sanderson from The University of Queensland on “The Power and the Puzzles of Auditory Interfaces.” This is a very interesting topic for many application domains.The IFIP Advances in Information and Communication Technology series is a publication that covers various aspects of information and communication technology.
