A Framework for Analysing, Designing and Evaluating Persuasive Technologies (original) (raw)

The use of interactive technology for changing, shaping or reinforcing attitude or behaviour which is commonly known as persuasive technology is currently attracting attention in information systems research. Persuasive technology combines the positive attributes of interpersonal interaction and mass communication to achieve optimal persuasion. It aims to accommodate individual difference during persuasion: a situation which is not commonly characterised with mass media persuasion. Amidst the benefits it brings to behavioural and attitudinal change interventions, current research have demonstrated that there is a lack of methods for its design. Consequently, most of the existing persuasive technology applications do not follow systematic processes during the design phases. As an attempt to remedy this situation, the Persuasive Systems Design (PSD) model has been introduced. However, although the PSD model provides a guide on what should be considered during analysis, design and evaluation, it fails to provide adequate information on how it should be done. Thus designers know what to do but not how to do it. To address this limitation, this study presents the 3-Dimensional Relationship between Attitude and Behaviour (3D-RAB) model and the Unified Framework for Analysing, Designing and Evaluating persuasive technology (U-FADE). The 3D-RAB argues that by analysing and identifying the various levels of cognitive dissonance of users before and during behaviour interventions, designers can craft persuasive messages to enhance persuasion. The U-FADE on the other hand expands the PSD model to include the 3D-RAB model and provide steps that can be followed to develop persuasive technology applications. The model and the framework were validated and it was observed that the U-FADE and the 3D-RAB are both effective for persuasive technology design.
