Usability Testing Tools for Web Graphical Interfaces

Software design and development following a user-centered approach can benefit from the adoption of adequate usability testing tools. However, the choice of a suitable tool for a particular purpose can be a difficult task, due to the multiplicity of such tools, each one offering a variety of different features. This paper surveys usability testing tools for web graphical interfaces, selects a set of appropriate tools and evaluates them. A set of relevant evaluation features is identified and aggregated into criteria. A multicriteria additive utility function and the Analytical Hierarchy Process are proposed as evaluation methods and for establishing a ranking of a selected set of usability testing tools. Results of both methods are presented and compared.
