Executive Summary

Motion Autocomplete is a sophisticated AI system that predicts physical movements and prepares context before actions occur. The system has evolved through 8 generations, with the current implementation featuring:

• ✅ Kinetic Chain Detection - Fully implemented via precursor detection
• ✅ Temporal Echo Patterns - Markov transitions + time-of-day patterns
• ✅ Bio-Sync Features - Circadian rhythm, HRV, respiratory coupling (newly added)
• ✅ Smart Home Integration - Zone-based device orchestration
• ✅ Voice Override - Natural language control

1. Kinetic Chain Implementation

Status: ✅ COMPLETE

The kinetic chain system is implemented through the Precursor Detector (`src/intent/precursor-detector.ts`), which detects micro-movements that precede major actions.

How It Works

The body broadcasts intent before conscious action. The system detects these precursors with 500-2000ms of lead time:

Kinetic Chain Patterns

The system recognizes biomechanically-grounded patterns:

Pre-Stand Sequence:
  weight-shift → hand-preparation → postural-adjustment → standing
  (2000ms window, +25% confidence boost)

Desk Departure:
  screen-disengage → grip-release → postural-adjustment → walking
  (3000ms window, +30% confidence boost)

Refreshment Seeking:
  weight-shift → gaze-redirect → screen-disengage → kitchen
  (2500ms window, +15% confidence boost)

Rest Preparation:
  muscle-tension → breathing-change → postural-adjustment → lying
  (4000ms window, +20% confidence boost)

#### Code Location
- `src/intent/precursor-detector.ts` - Core precursor detection
- `src/intent/intent-engine.ts` - Intent inference from chains
- `src/sensors/sensor-fusion.ts` - Multi-sensor data fusion

2. Temporal Echo Patterns

Status: ✅ COMPLETE

The system learns and uses temporal patterns at multiple scales.

2.1 Markov Transition Matrix

Location: `src/predictor/engine.py` (TransitionMatrix class)

Records observed transitions and calculates probabilities:

# Example learned transitions
sitting_down → rising_from_chair (0.45)
sitting_down → reaching (0.30)
sitting_down → leaning (0.25)

standing_up → walking_generic (0.50)
standing_up → sitting_down (0.35)
standing_up → stretching (0.15)

The matrix updates in real-time as movements are observed, with probability normalization.

2.2 Time-of-Day Patterns

Location: `src/predictor/engine.py` (TemporalPredictor class)

Learns hourly movement patterns:

2.3 Goal Profile Time Biases

Location: `src/intent/intent-engine.ts`

Each intent category has hourly bias weights (0-1):

// Peak hours for refreshment-seeking: 8, 10, 14, 16
timeOfDayBias: [0.3, ..., 0.9(8), 0.6(9), 0.9(10), ..., 0.9(14), ...]

// Peak hours for rest-seeking: 13, 22, 23
timeOfDayBias: [0.3, ..., 0.9(13), ..., 0.9(22), 0.9(23), ...]

2.4 Historical Pattern Learning

The system continuously learns from outcomes:
- Records actual vs predicted movements
- Adjusts confidence based on historical accuracy
- Teaches precursor detector new patterns
- Maintains 7-day rolling history

---

3. Bio-Sync Features

Status: ✅ COMPLETE (Enhanced)

Bio-sync features align predictions with biological rhythms.

3.1 Circadian Rhythm Engine (Gen 8)

Location: `src/bio/circadian-rhythm.ts`

Chronotype Detection:
- Early Bird (wake ~5:30, peak 7-11)
- Intermediate (wake ~7:00, peak 9-12)
- Night Owl (wake ~9:00, peak 14-18)

Circadian Phases:

Activity Alignment Scoring:

// Scores how well an activity fits the current phase
scoreActivityAlignment('deep-work', 9am) → 100%  // Peak cognitive
scoreActivityAlignment('deep-work', 2pm) → 40%   // Midday dip

3.2 HRV-Based Readiness (NEW)

Location: `src/bio/bio-sync.ts`

Calculates readiness from Heart Rate Variability:

interface HRVMetrics {
  sdnn: number;        // Standard deviation of NN intervals
  rmssd: number;       // Root mean square of successive differences
  lf: number;          // Low frequency (sympathetic)
  hf: number;          // High frequency (parasympathetic)
  lfHfRatio: number;   // Autonomic balance
  readinessScore: number; // 0-100
}

// Higher RMSSD = more parasympathetic = more recovered
// Lower LF/HF ratio = better balance

3.3 Respiratory Coupling (NEW)

Location: `src/bio/bio-sync.ts`

Synchronizes movement initiation with breath phase:

getBreathCoupledMovementTiming() → {
  waitMs: 0,              // Exhale phase - optimal for movement
  phase: 'now',
  reason: 'Exhale phase - optimal for movement initiation'
}

// Research shows movement is most efficient when initiated during exhale

3.4 Ultradian Rhythm Tracking (NEW)

Location: `src/bio/bio-sync.ts`

Tracks 90-120 minute energy cycles:

interface UltradianCycle {
  cycleNumber: number;      // Which 90-min cycle since wake
  phaseMinutes: number;     // Minutes into current phase
  energy: 'rising' | 'peak' | 'falling' | 'trough';
  nextTransition: number;   // Minutes until next phase
  recommendedActivity: string;
}

// Cycle phases: 0-25% rising, 25-50% peak, 50-75% falling, 75-100% trough

3.5 Fatigue Modeling (NEW)

Location: `src/bio/bio-sync.ts`

interface FatigueModel {
  muscularFatigue: number;   // From recent activity
  cognitiveLoad: number;     // From focus time
  postureStrain: number;     // From static positions
  overallFatigue: number;    // Composite (0-100)
  recoveryNeeded: number;    // Minutes of rest needed
}

3.6 Movement Readiness Assessment (NEW)

Location: `src/bio/bio-sync.ts`

getMovementReadiness() → {
  readyForMovement: true/false,
  confidence: 0.85,
  blockingFactors: ['High fatigue', 'Low HRV'],
  enhancingFactors: ['Peak energy phase', 'Good coherence'],
  suggestedAction: 'Movement appropriate' | 'Rest recommended'
}

4. Smart Home Integration

Status: ✅ COMPLETE

Location: `src/smarthome/device-orchestrator.ts`

Zone-Based Orchestration

Predictive Preparation

1. Precursor detected → Start device preparation
2. Intent inferred → Queue relevant actions
3. Confidence > 70
4. Arrival confirmed** → Complete transitions

Circadian-Aware Lighting

getRecommendedLighting() → {
  temperature: 4500, // Kelvin based on phase
  brightness: 76     // % based on energy level
}

---

5. Voice Override System

Status: ✅ COMPLETE

Location: `src/voice/voice-override.ts`

Wake Words: "hey home", "ok motion", "computer" (customizable)

---

6. Sensor Fusion

Status: ✅ COMPLETE

Location: `src/sensors/sensor-fusion.ts`

Combines multiple sensor inputs with weighted confidence:

---

7. Privacy & Health Features

Status: ✅ COMPLETE

Health Insights: `src/health/pattern-insights.ts`
- Sitting time alerts (>60 min threshold)
- Eye strain detection (20-20-20 rule)
- Standing goal tracking
- Afternoon energy dip detection

Privacy Principles:

- Fix strict type checking issues in `src/index.ts`

2. Missing Exports:
- Add `BioSync` to main module exports
