A Framework Based on Ajax and Semiotics to Build Flexible User Interfaces

Different users have different needs; thus, user interfaces, especially in the web, should be flexible to deal with these differences. In this work we present the FAN Framework (Flexibility through AJAX and Norms) for implementation of tailorable user interfaces. The framework is based on the semiotic concept of norms and was developed with web technologies such as Ajax and PHP. The proposed framework was applied to the Vilanarede system, an inclusive social network system developed in the context of e-Cidadania project, and tested with real users. We present the tests results and a discussion about the advantages and drawbacks of the proposed solution, as well as a preliminary analysis of the use of two tailorable functionalities during the first year.
