The 12 CMCC Coherence Features

Human interaction is governed by cognitive and neuromuscular constraints. CORROBORATE extracts 12 cross-channel temporal features across 4 distinct biomechanical groups.

1. Interactive Feature Sandbox & Parameter Tester

Adjust simulated motor timing parameters in real-time to watch how the mathematical coherence score responds.

MIDTGroup A: Attentional Exclusivity

Mouse Idle During Typing Ratio

Measures whether cursor movement halts while keystrokes are being emitted.

Biomechanical Basis & Literature:

Card-Moran-Newell KLM homing model dictates that an attending human hand cannot operate the mouse and keyboard simultaneously. High mouse velocity during typing indicates automated multi-threading or synthetic desync.

Typical Human Range0.92 – 1.00
Bot / Splice Range0.10 – 0.65
Parameter Slider50 ms
0 ms1000 ms
COHERENT (AUTHENTIC)
0.929

Parameter aligns within calibrated genuine human motor limits.

Comprehensive formulas, cognitive definitions, and expected threshold boundaries derived from the FYP proposal.

Group A: Attentional Exclusivity
MIDT0.92 – 1.00

Mouse Idle During Typing Ratio

Measures whether cursor movement halts while keystrokes are being emitted.

Biomechanical Basis:Card-Moran-Newell KLM homing model dictates that an attending human hand cannot operate the mouse and keyboard simultaneously. High mouse velocity during typing indicates automated multi-threading or synthetic desync.
Typical Human: 0.92 – 1.00
COC250ms – 550ms

Concurrent Operation Cost

Penalizes zero-latency transitions between distinct modality channels.

Biomechanical Basis:Physical transit time of moving the dominant hand between pointing device and home row (~400ms homing operator, Card et al. 1980).
Typical Human: 250ms – 550ms
PPX< 0.02

Parallel Pointer-Key Cross-Rate

Instantaneous cross-channel event density within micro-windows.

Biomechanical Basis:Cognitive bottleneck theory (Pashler 1994) confirms central attentional limits prevent concurrent motor programming for distinct effectors.
Typical Human: < 0.02
Group B: Causal Ordering & Motor Transitions
PPF80ms – 400ms lead

Pointer Precedes Focus Latency

Checks if cursor trajectory physically leads focus acquisition.

Biomechanical Basis:In pointer-driven interactions, visual targeting (gaze) precedes ballistic cursor movement, which precedes element activation.
Typical Human: 80ms – 400ms lead
KOL180ms – 420ms

Keystroke Onset Lag

Latency between clicking into an input field and the first character keydown.

Biomechanical Basis:Cognitive decision time to process input focus plus motor initiation of keystroke cadence (~150-450ms).
Typical Human: 180ms – 420ms
STI200ms – 600ms

Scroll-to-Interact Latency

Settling time between viewport deceleration and subsequent interaction.

Biomechanical Basis:Visual fixation duration required to re-acquire target coordinates following page motion.
Typical Human: 200ms – 600ms
ABC300ms – 1100ms

Action-Before-Commit Hesitation

Pre-submission micro-pauses reflecting task confirmation.

Biomechanical Basis:Final verification hesitation observed in genuine human transactions.
Typical Human: 300ms – 1100ms
CIANormal distribution around center

Click-to-Input Alignment

Spatial-temporal bounding of clicks relative to input bounding boxes.

Biomechanical Basis:Fitts' Law motor distribution around visual center of clickable targets.
Typical Human: Normal distribution around center
Group C: Rhythm & Identity Coupling
IPCPositive correlation (r > 0.45)

Inter-Channel Pace Correlation

Correlation between mouse velocity cadence and typing speed bursts.

Biomechanical Basis:Individual arousal level and cognitive tempo co-modulate across all motor modalities.

Rhythm Variance Consistency

Stability of micro-pause distributions across form episodes.

Biomechanical Basis:Unique individual motor profile (biometric fingerprint consistency).
Typical Human: 0.25 – 0.55
Group D: Task-Structural Coherence
FEC1.0

Field-Episode Completeness

Validates that entry, keystroke modification, and blur form a complete episode.

Biomechanical Basis:Human mental model processes form fields as discrete cognitive chunks.
Typical Human: 1.0
FTI> 0.85

Form-Traversing Interleaving Pattern

Logical progression across DOM elements versus random injection.

Biomechanical Basis:Visual flow adheres to layout reading order (Z-pattern / F-pattern).
