User-centered Interface Design
Nowadays, it is a fact that using a computer more and more often implies interacting with some kind of visual formalism. Practically, any application has a graphic interface, in which the various operations necessary to interact with it are achieved by pressing buttons, selecting items from menus, manipulating icons, etc.
This is the result of a continuing process starting with the birth of computer science and destined to lead human-computer interaction towards models which are ever closer to the user and his or her way of conceiving communication with the machine. However, the very great expressive power characterizing some visual systems may lead, if not properly managed, to interaction models which are hard to control from the human-computer interaction point of view.
Our research is focused on the development of new interaction paradigms for visual interfaces (with special attention to the Web), as well as on the identification of Usability criteria for their design.
