Can things in one’s household(e.g. lightings, TVs, refrigerators) help people to become more healthy? Conventional health promoting products, such as activity trackers, provide health interventions to encourage health behavior change. However, these products provide a pre-fabricated solutions for desired behavior, often dismissing the personalized needs. Contrary to proposing automated solutions for target behavior, recent works investigate the creation of user-driven solutions for effective behavior change. With the growing market of Do-it-yourself(DIY) styles in IoT products, this study attempts to apply DIY methods for creating personalized and precise health behavior change interventions. In this study, we will propose a DIY IoT intervention design tool for users to develop their own health interventions by exploring how people assemble interactions with multiple IoT devices.
Health-related IT products (e.g., Fitbit) support persuasive technologies to reinforce an individual's desired behaviors. While these products are dedicated to certain health behaviors, such as walking or specific types of sports, IoT at home can be integrated more broadly throughout one's daily life. To address this opportunity, this paper aims to shed light on the use of domestic IoT that can foster changes toward healthy behaviors through a 3-week explorative field trial. This paper reports two major goals of health-promoting technologies using IoT as well as different persuasive techniques according to the temporal phases of before, during, and after the health behaviors.
