A Model for Universal Usability on the Web.
Rui Lopes, Luís M. Carriço · 2008
This paper presents a theoretical model to study the univer-sal usability of the Web, i.e., how usable websites are to a wide range of audiences. We define a set of universal usabil-ity metrics (UUM) to be applied into Web portions (e.g., websites, clusters) at different abstraction levels. Model in-stances afford studying evolution patterns of the Web (e.g., Reachability, Verticality) from a universal usability perspec-tive. This leverages new knowledge that can be used to both explain adequacy of websites to the particularities of users, as well as pointing out future directions for Web standards.
