Transforming Sociotech Design (TSD) uncovers conceptual frameworks for designing and evaluating Persuasive Technology (PT) aimed at achieving sustainable transformations of our lives towards wellbeing. TSD explains ways how PT research can be extended beyond limitations of traditional behavioral change designs. TSD embodies fundamental understanding of the essentials for designing successful transformations, known as Socially Influencing Systems, Computer-Supported Influence, Persuasive Cities, Persuasive Backfiring, and Persuasive Design for Sustainability. TSD empowers researchers and designers to create PT that makes behavioral and attitudinal changes last. Moreover, TSD also shares the knowledge about strategies from rhetoric, psychology, and neuroscience that lead to attitudinal transformations. By definition, TSD expands the way how researchers and professionals see the potential of PT in attaining long-term permanent behavioral changes at all scales, be it an individual, group, or societal levels. Everyone interested in creating innovations that successfully transform human behavior and attitude is welcome to explore more, especially PT researchers and practitioners, including designers, developers, user experience experts, psychologists, gamifyers, and nudging enthusiasts.
