This book constitutes the thoroughly refereed post-proceedings of the Second International Conference on Persuasive Technology for Human Well-Being, PERSUASIVE 2007, held in Palo Alto, CA, USA, in April 2007.

The 37 revised full papers presented were carefully reviewed and selected from numerous submissions for inclusion in the book. The papers are organized in topical sections on technology that motivates health behavior, persuading people with video games, new form factors for persuasive technology, surrounded by high-tech persuasion, controlling people by using digital punishment, technology that motivates groups to unify, how peers influence you online, new insights into web persuasion, persuasive agents on the screen, using digital images to persuade, persuasion via mobile phones, insights into persuasion principles, and perspectives on persuasive technology.

Can computers change what you think and do? Can they motivate you to stop smoking, persuade you to buy insurance, or convince you to join the Army?
"Yes, they can," says Dr. B.J. Fogg, director of the Persuasive Technology Lab at Stanford University. Fogg has coined the phrase "Captology"(an acronym for computers as persuasive technologies) to capture the domain of research, design, and applications of persuasive computers.In this thought-provoking book, based on nine years of research in captology, Dr. Fogg reveals how Web sites, software applications, and mobile devices can be used to change people's attitudes and behavior. Technology designers, marketers, researchers, consumers-anyone who wants to leverage or simply understand the persuasive power of interactive technology-will appreciate the compelling insights and illuminating examples found inside.
Persuasive technology can be controversial-and it should be. Who will wield this power of digital influence? And to what end? Now is the time to survey the issues and explore the principles of persuasive technology, and B.J. Fogg has written this book to be your guide.

Improving your life is much easier than you think. Whether it's losing weight, sleeping more, or restoring your work/life balance - the secret is to start small. For years, we've been told that being more healthy and productive is a matter of willpower: that we should follow the latest fad and make constant changes to our lifestyles. But whether in our diets, fitness plans or jobs, radical overhauls never work. Instead we should start with quick wins - and embed new, tiny habits into our everyday routines. The world expert on this is Silicon Valley legend BJ Fogg, pioneering research psychologist and founder of the iconic Behaviour Design Lab at Stanford. Now anyone can use his science-based approach to make changes that are simple to achieve and sticky enough to last. In the hugely anticipated Tiny Habits, BJ Fogg shows us how to change our lives for the better, one tiny habit at a time. Based on twenty years research and his experience coaching over 40,000 people, it cracks the code of habit formation. Focus on what is easy to change, not what is hard; focus on what you want to do, not what you should do. At the heart of this is a startling truth - that creating happier, healthier lives can be easy, and surprisingly fun.
