RhythmSync Measurement Engine

Measure state as timing, geometry, and movement.

A research interface for mapping rhythmic inputs into coordinate-based state movement.

Each input becomes a coordinate point. Across a rolling window, the engine tracks where the system is, how it is moving, and whether organization is beginning to form.

Prototype measurement tool. Not clinical. Not diagnostic. No semantic emotion labels.

How it works

The engine computes state-space observables including vector position, entropy, dominance, distance-to-vertices, and rolling-window movement.

Research use

Designed for measurement and reproducibility. RhythmSync supports research questions about state movement, not only condition differences.

Δt note: Δt is event-locked only when an external event marker is supplied. Without an event marker, Δt proxy reflects within-window convergence timing, not event prediction.

Input signal

Enter a signal sample or short text proxy. Each analysis creates one coordinate point and updates the rolling trajectory window.

window: 0 / 5

Current coordinate point

Where the current input sits in coordination space.

A dominance ratio of 1 indicates no dominant coordinate / tie.

Timing layer / Δt

When coordination begins to stabilize before an event or shift.

Δt is event-locked only with an external event marker. In text-only/proxy mode, Δt proxy is a within-window convergence statistic.

Rolling trajectory

How state moves across the rolling window.

No window data yet.

State-space geometry

Distance-to-vertices trajectories across the rolling window.

Each input adds one coordinate point. Curves show how the point moves relative to simplex vertices v1–v5. Geometry-only.

Coordinate-space interpretation

State as movement through coordination space rather than a single arousal score.

current mode: text-only proxy + physiology-informed coordinate model

coordinate position: available after analysis

within-window movement: available after ≥2 points

global magnitude: requires physiological input

state-profile pattern: requires physiological input

Coordinate-space research gives the map. Δt research gives the timing. RhythmSync models the movement.

Physiology pattern

Optional physiology-informed pattern output when returned by the engine.

physiology_pattern: No physiology pattern returned yet.

Definitions for interpretation

state_vector s(t): 5D simplex coordinate, geometry-only. No semantic labels.
entropy: Shannon entropy, H(s) = −∑ sᵢ log sᵢ.
dominance_ratio: max(s)/second_max(s).
distance_to_vertices: distances to simplex vertices v1..v5.
windowed_trial: within-window dynamics over last ≤5 points.
Δt_proxy_ms: t_convergence − t_now, where convergence is defined within the output.
