First validation of persuasive criteria for designing and evaluating the social influence of user interfaces: Justification of a guideline

Abstract

Ergonomics has often produced grids to measure the ergonomic quality of goods and services. This paper seeks to establish and validate a grid to focus on the persuasive dimensions of interfaces and their effects; a grid that is robust, reliable, useful, relevant and easy to use for ergonomists, usability engineers and interaction designers. Our purpose is to develop and validate guidelines to measure and assess the persuasive dimensions of user experiences. This research based on a criteria model will become helpful in researching and designing persuasive technology. At first we propose a criteria-based approach to measure persuasive strength of interfaces; this criteria grid includes eight criteria: Credibility, Privacy, Personalization, Attractiveness, Solicitation, Priming, Commitment, and Ascendency. At the end, these criteria are validated by a sample of 30 experts, who confirmed that the proposed categorization of the criteria (from 71.30% to 83.25%). © 2011 Springer-Verlag.
