Persuasive technology is broadly defined as technology that is designed to change attitudes or behaviors of the users through persuasion and social influence, but not through coercion.[1] Such technologies are regularly used in sales, diplomacy, politics, religion, military training, public health, and management, and may potentially be used in any area of human-human or human-computer interaction. Most self-identified persuasive technology research focuses on interactive, computational technologies, including desktop computers, Internet services, video games, and mobile devices,[2] but this incorporates and builds on the results, theories, and methods of experimental psychology, rhetoric,[3] and human-computer interaction. The design of persuasive technologies can be seen as a particular case of design with intent.[4]
