Abstract:
Persuasive technologies for promoting physical fitness, good nutrition and other healthy
behaviors have been growing in popularity. Despite their appeal, the design and evaluation
of these technologies remains a challenge and usually require a fully functional prototype
and long term deployment just like any other information system. Hence, the focus of this
paper is to review some persuasive and behavioral change models used in designing and
evaluating persuasive technologies and identify their inherent limitations. To achieve the
stated objectives, the systematic review method of research was done to understand the
various persuasive system models and relevant information was extracted using the
Inductive approach. Currently, the Persuasive System Design (PSD) framework is
considered to be one of the commonly and most comprehensive framework for designing
and evaluation of persuasive systems. However, some of its design features overlap and are
difficult to analyze. This review research has brought to light the need to extend the PSD
theoretical model with a measurable and integrated usability model which can adequately
measure the efficiency and effectiveness of persuasive design outputs at the early phase of
persuasive system development in future studies.
