Breathing Dynamics Showcase

Use this page when you need deterministic high-vs-low entropy figures plus appendix cases for rising variability, not-ready breathing, and stale breathing input.

This page uses entropy_high and entropy_low as the canonical pair for showing how the breathing waveform becomes accepted extrema, derived interval and amplitude series, and then the published entropy-oriented telemetry. The feature family follows the breathing-dynamics framing described by Goheen et al. (2025), while remaining explicit that this repository applies those features to the repo's calibrated ACC-derived breathing waveform rather than to a respiration belt signal.

Computation Path

WaveformSamples
-> AcceptedExtrema
-> IntervalSeries / AmplitudeSeries
-> Interval.SampleEntropy / Amplitude.SampleEntropy
  • Dynamics.Diagnostics.WaveformSamples exposes the breathing waveform used for the dynamics solve.
  • Dynamics.Diagnostics.AcceptedExtrema exposes the accepted peaks and troughs extracted from that waveform.
  • Dynamics.Diagnostics.IntervalSeries and AmplitudeSeries expose the derived breath timing and excursion-depth series.
  • Dynamics.Telemetry.Interval.SampleEntropy, Dynamics.Telemetry.Amplitude.SampleEntropy, and TrackingState expose the final downstream values and edge states published by the app.

Interpretation Notes

  • The waveform plotted here is a normalized ACC-derived breathing signal, so the amplitude axis is intentionally reported in arbitrary units.
  • The feature family is methodologically aligned to the cited breathing-dynamics paper, but the signal source is an app-specific adaptation and should be described that way in manuscripts.

Appendix And Edge States

The appendix figure keeps the extra publication cases in the same bundle:

flat_breathing keeps entropy unavailable because the excursion never clears the acceptance thresholds. breathing_pause documents the Stale end state after the waveform stops updating near the end of the scenario.
