ABSTRACT
Recently, computer-based products have become associated with a great amount of daily user activities, such as work, communication, education, entertainment, and so on. eir target population has changed dramatically. Users are no longer only traditional able-bodied, skilled, and computer-literate professionals. Instead, users are potentially all citizens. At the same time, the type and context of use of information and services is radically changing due to the increasing availability of novel access platforms, such as personal digital assistants, kiosks, cellular phones, and other network-attachable equipment, which progressively enable nomadic access to information and services (Stephanidis, 2001). ese changes signal the emergence of the information society, the success of which relies to a signifi cant degree on the opportunities off ered to all citizens to obtain and maintain access to a society-wide pool of information resources and communication facilities, given the variety of context. To this end, accessibility in its broader sense (as the “ability to access” the functionality, and possible benefi t, of some system, irrespective of where and how it runs) is considered to be of paramount importance.
