INTERACT 2007 was the 11th of a series of INTERACT international conf- ences supported by the IFIP Technical Committee 13 on Huma – Computer Interaction. This year, INTERACT was held in Rio de Janeiro (Brazil), or- nized by the Informatics Department at the Pontifcia Universidade Catlica do Rio de Janeiro, with the support of PETROBRAS, CGI. BR (Comit Gestor da Internet no Brasil), and Microsoft. Likeitspredecessors,INTERACT2007highlighted,toboththeacademicand industrialworld,theimportanceofthehuman–computerinteraction(HCI)area and its most recent breakthroughs on current applications. Both experienced HCI researchers and professionals, as well as newcomers to the HCI ?eld, int- ested in designing or evaluating interactive software, developing new interaction technologies, or investigating overarchingtheories of HCI, found in INTERACT 2007 a great forum to communicate with people with similar interests, to - courage collaboration, and to learn. INTERACT 2007 had “socially responsible interaction as its special theme. Human beings have evolved for many millennia; during most of that time, our major social contacts were within small, tightly knit groups who shared a c- mon language culture and physical context. In the last historical eyeblink, we rather suddenly ?nd ourselves part of a global community. We have very d- ferent cultures, languages, perspectives, and physical contexts. Moreover, as a species, we face the possibility of bringing about our own extinction if we c- not solvesome exceedinglychallengingproblems. Our individual brainpowerhas notincreasedsigni?cantlyin the last100,000years. Computing andcommuni- tion technologieso?er some potential, however,to increasegreatly our collective intelligence and creativity.
