U-FADE: A Unified Approach To Persuasive Systems Development

Although persuasive technology continues to impact behavioural and attitudinal interventions, research has demonstrated that existing design approaches are faced with limitations that impede their effective use. Mostly, they become obsolete, as user needs change during the use of the persuasive application. This research therefore proposes the Unified Framework for Analysing, Designing and Evaluating persuasive systems U-FADE. The proposed framework integrates concepts from various existing models to provide a systematic approach that facilitates persuasive design. It addresses the issue of changing needs of users by considering external and internal activities that may promote or impede persuasion before and during implementation.
