Graphical User Interfaces, Usability, and Accessibility

Almost always, using a computer means interacting with visual formalisms. However, some visual systems may lead to interaction models which are counterintuitive and difficult to control. The research of Marco Porta in this area has 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 effective design. Moreover, the interaction with mobile robots and advanced web query systems has been considered, also in the context of European projects.
