Explainable Persuasion in Interactive Design

Persuasive technology refers to the use of digital means to influence attitude, behaviour, and decisions. While a professional design of persuasive interfaces shall consider user interests and freedom of choice as a primary requirement, principles, and methods to achieve it are yet to be introduced. In the design of persuasive interfaces, fulfilling conditions of informed consent can help establish transparency and resolve such ethical issues. This paper introduces the concept of explainable persuasion as a way to address informed consent within persuasive interfaces. We provide a definition for explainable persuasion, highlight the need for it, discuss the design approach and underline the challenges to be addressed when designing explainable persuasive interfaces.
