We will be, sooner or later, not only handling personal computers but also mul- purpose cellular phones, complex personal digital assistants, devices that will be context-aware, and even wearable computers stitched to our clothes...we would like these personal systems to become transparent to the tasks they will be performing. In fact the best interface is an invisible one, one giving the user natural and fast access to the application he (or she) intends to be executed. The working group that organized this conference (the last of a long row!) tried to combine a powerful scientific program (with drastic refereeing) with an entertaining cultural program, so as to make your stay in Rome the most pleasant one all round: I do hope that this expectation becomes true. July 2005 Stefano Levialdi, IEEE Life Fellow INTERACT 2005 General Chairman [1] Peter J. Denning, ACM Communications, April 2005, vol. 48, N° 4, pp. 27-31. Editors' Preface INTERACT is one of the most important conferences in the area of Human-Computer Interaction at the world-wide level. We believe that this edition, which for the first time takes place in a Southern European country, will strengthen this role, and that Rome, with its history and beautiful setting provides a very congenial atmosphere for this conference. The theme of INTERACT 2005 is Communicating Naturally with Computers.
