Enhancing persuasive features of Behaviour Change Support Systems: The role of U-FADE

The introduction of Behaviour Change Support Systems (BCSS) has enhanced the ability of utilizing computing technology and information systems for changing or altering human behaviour or attitude. Yet, some existing BCSS applications are faced with limitations that impede their effective use because they become obsolete as user needs change during it use. The Unified Framework for Analysing, Designing and Evaluating persuasive systems (UFADE), has been introduced to address these limitations. However, the framework has not been applied in the development of any BCSS application. This research evaluates the U-FADE by applying its design principles to an existing weight management application (ObiMo Pet). Our findings support claims that U-FADE is capable of facilitating BCSS development. It was also observed that by applying the framework, extra system features are identified which may possibly enhance the persuasiveness of the application.
