Does real-time HRV biofeedback training improve emotion-related heart rhythm oscillation modes in subhealth subjects?
A wearable HRV biofeedback system may help subhealth subjects manage negative emotions by transforming their heart rhythm into positive oscillation modes.
Negative emotion has a wide range of pernicious impacts on people, ranging from the failure in real-time task performance to the development of chronic health conditions. An unobtrusive wearable biofeedback system for personalized emotional management has been designed and presented in this paper. The system integrated heart rate variability (HRV) biofeedback to wearable biosensor platform, which could function both as an early stress warning system as well as a visual interface to manipulate subject's affective state. The designed and developed system would help subject to transform the negative emotion state into positive through real-time HRV biofeedback training. The results indicated that the real-time HRV biofeedback is significantly effective in cases of negative emotion. With the aid of the developed biofeedback system, the subhealth subjects could transform heart rhythm from negative emotion to positive emotion-related oscillation mode.
