EcoIsland visualizes the user's current eco-friendly behavior as an island shared by his/her family members. Several persuasive techniques developed in behaviorism, social psychology, and economy are used to offer incentives to him/her to encourage eco-friendly behavior. We examine and compare the implementation and effectiveness of different types of persuasive techniques in several user studies. %@ 978-1-60558-376-1
