Making Food with the Mind: Integrating Brain-Computer Interface and 3D Food Fabrication

Abstract

We presented “Mind-Controlled 3D Printer” that translates brain signals from the user into 3D printed food. This system integrated an EEG recording device that measures neural activities in real-time with a machine learning algorithm that classify emotional valence and arousal levels, which determine the shape and size of the food fabricated by the food 3D printer. This research introduced the opportunity for combining brain-computer interface (BCI), affective computing, and additive manufacturing technology, which will ultimately enable the automation of mind to matter materialization. We demonstrated three use cases and envisioned the future research on BCI and food fabrication.
