This project investigates the implications surrounding increased data collection in a domestic setting. Applying a research through design approach, the project uses sketching and prototyping as a way to materialize and explore the field. Topics such as privacy and Big Data are explored, and the complex relationship between people and data gathering is investigated. This relationship is embodied in the final prototype, an interactive creature named Tomo, which feeds on the data people produce in their homes. The design of Tomo seeks to communicate these issues applying theory on information visualization, facilitating attachment between humans and computational artefacts and expression of emotion in robotics.
