Reflecting on Solo Dining Behavior with Annotated Data Physicalization

Using information and communication technology (ICT) while solo dining can alleviate loneliness but may also lead to unhealthy food choices and decreased satiety. Mindful eating practices are needed to raise awareness about the impact of ICT technology on eating behavior. Our work aims to use technology to augment physical practices and generate physical artifacts by physicalizing sensor data and letting users self-annotate and make sense of the sensor data. With a toolkit that supports constructive physicalization of inertia sensor data related to the users' eating behavior, users increase their awareness of their mundane routine of solo dining with ICT devices by building personalized data physicalization and adding annotations. Results of a five-day preliminary study indicate how annotating data physicalization could be a beneficial intervention for promoting mindful eating behavior in a personal context.
