Personal informatics in everyday life.

ABSTRACTPersonal informatics is becoming increasingly prevalent. The lived informatics perspective considers the everyday behaviors people experience while tracking, such as switching tools, forgetting to track, or giving up on tracking. My work furthers theory, design, and implementation of lived informatics in technology. I contribute a theoretical framework to characterize how people use self-tracking tools in practice, independent of their original motivation to track. I design and build technology for analyzing personal data, improving sharing experiences around physical activity data, and promoting food mindfulness.
