Personal informatics in the wild: hacking habits for health & happiness.

Personal informatics is a class of systems that help people collect personal information to improve self-knowledge. Improving self-knowledge can foster self-insight and promote positive behaviors, such as healthy living and energy conservation. The development of personal informatics applications poses new challenges in human-computer interaction and creates opportunities for applications in various domains related to quality of life, such as fitness, nutrition, wellness, mental health, and sustainability. This workshop will continue the conversations from the 3 previous CHI workshops through discussions on practical lessons from previous research and development experiences. In particular, this workshop will extend this ongoing work through a focus on rapid prototyping and deployment in the wild. Topics covered will include designing interfaces for collecting and reflecting on personal data, building robust applications, and infrastructures to make applications easier to create.
