Emotion recognition using heart rate data from a wearable smartwatch.



Our data are never just numbers. They speak. Even the intangible, abstract and private can be brought to light through algorithmic mediation. The project aims therefore to raise awareness about the pervasiveness of data collection, which manage to detect and interpret every aspect of our lives, including the most intimate sphere of emotions.

—About the project

"NaN-Not (just) a Number" is an open window on one of the daily collected datasets (in this case, the biomedical measurements of a smartwatch) and its algorithmic interpretation (specifically, the stress recognition). The result is a generative artwork that, through a data-driven approach, provides a new exploratory experience of the dataset, turning it into a human-understandable language.
