AcqKnowledge calculates heart rate variability (HRV) using the Welch Periodogram and least squares de-trending methods.
To properly select the parameter values needed for the calculation of the Power Spectral Density, which is the “work-horse” tool for Heart Rate Variability analysis, a brief tutorial is presented, including an R-R Interval Processing Approach.
The Welch Periodogram is a method by which a large time-sampled waveform can be frequency-transformed by partitioning the data into shorter segments, transforming each segment, then, averaging the results over all the segments to create a composite frequency space waveform.
Synchronizing Data from Multiple Participants Performing a dyadic experiment takes more planning than single-participant studies. Data must be tightly synchronized, equipment must remain inobtrusive, and the experimental paradigm drives the optimal setup. Join us to learn how to record high-quality synchronized data for a wide range of applications.
What You Will Learn: – How to synchronize data from two participants – Recording options: ECG, EDA, EEG, fNIRS, Video – Collaborative virtual environments – Data analysis techniques – Practical tips—and advice on working with children – New ideas about your research
