Considering Gut Biofeedback for Emotion Regulation
This work addresses the problem of limited emotion regulation tools for researchers and practitioners by introducing a potential new measurement method, though it appears incremental as it builds on known autonomic nervous system measures.
The paper proposes using electrogastrography (EGG) to measure gastrointestinal activity as a novel approach for inferring human emotions, highlighting the neglect of gut signals in existing biofeedback applications.
Recent research in the enteric nervous system, sometimes called the second brain, has revealed potential of the digestive system in predicting emotion. Even though people regularly experience changes in their gastrointestinal (GI) tract which influence their mood and behavior multiple times per day, robust measurements and wearable devices are not quite developed for such phenomena. However, other manifestations of the autonomic nervous system such as electrodermal activity, heart rate, and facial muscle movement have been extensively used as measures of emotions or in biofeedback applications, while neglecting the gut. We expose electrogastrography (EGG), i.e., recordings of the myoelectric activity of the GI tract, as a possible measure for inferring human emotions. In this paper, we also wish to bring into light some fundamental questions about emotions, which are often taken for granted in the field of Human Computer Interaction, but are still a great debate in the fields of cognitive neuroscience and psychology.
