HRV (Heart Rate Variability) gives significant information on Autonomic Nervous System (ANS)’s regulating function and balance status. The variation of heart rate during short term (5 minutes) is analyzed in our system with the method of time domain and frequency domain to provide the degree of balance and activity of autonomic nervous system.
How we visualise bio-data and map in the interface?
IBI (interbeat interval) is connected to velocity of fish.
SDNN (Stand deviation of normalized IBI) is connected to the bubbles and transparency of fish.
