## 🌟 Overview

The WIA-AUG-004 standard defines comprehensive protocols and frameworks for sensory enhancement technologies, including sensory range expansion, multi-sensory integration, sensory substitution systems, and novel sense development.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to expand human sensory capabilities safely and effectively, enabling people to perceive and interact with the world in new and enhanced ways while maintaining sensory health and preventing overload.

## 🎯 Key Features

- **Sensory Modality Classification**: Standardized categorization of all human senses
- **Enhancement Spectrum**: Clear framework from restoration to new sense development
- **Range Expansion Protocols**: Safe methods to expand sensory perception ranges
- **Multi-Sensory Integration**: Protocols for combining multiple enhanced senses
- **Sensory Substitution**: Standards for replacing one sense with another
- **Perception Calibration**: Methods to calibrate enhanced sensory perception
- **Overload Protection**: Mechanisms to prevent sensory overload and damage
- **Cross-Modal Mapping**: Standards for translating between sensory modalities

## 📊 Core Concepts

### 1. Sensory Modality Types

```
Primary Senses:
├── Visual (Light: 380-750nm)
├── Auditory (Sound: 20Hz-20kHz)
├── Tactile (Touch, pressure, vibration)
├── Olfactory (Chemical detection - smell)
├── Gustatory (Taste receptors)
├── Proprioceptive (Body position)
└── Vestibular (Balance, spatial orientation)

Extended Senses:
├── Thermoception (Temperature)
├── Nociception (Pain)
├── Equilibrioception (Balance)
└── Interoception (Internal states)
```

### 2. Enhancement Types

```
Restoration: Normal range → Impaired → Normal
Augmentation: Normal range → Extended range
New Sense: No existing sense → Novel perception
Substitution: Missing sense → Alternative sense
```

### 3. Sensory Range Formula

```
Enhanced Range = Base Range × Enhancement Factor × Safety Margin
```

Where:
- `Base Range` = Normal human sensory range
- `Enhancement Factor` = Augmentation multiplier (1.0-10.0)
- `Safety Margin` = Overload protection factor (0.8-0.95)

### 4. Integration Quality Score

```
Integration Score = (Sync × Fidelity × Bandwidth) / Latency
```

Where:
- `Sync` = Temporal synchronization (0-1)
- `Fidelity` = Signal accuracy (0-1)
- `Bandwidth` = Information throughput
- `Latency` = Processing delay (ms)

## 🔧 Components

### TypeScript SDK

```typescript
import {
  classifySensory,
  enhanceModality,
  calibratePerception,
  preventOverload,
  mapCrossModal,
  integrateMultiSensory
} from '@wia/aug-004';

// Classify sensory enhancement
const classification = classifySensory({
  modality: 'VISUAL',
  enhancementType: 'AUGMENTATION',
  targetRange: { min: 300, max: 1000, unit: 'nm' }
});

// Enhance a sensory modality
const enhanced = enhanceModality({
  modality: 'AUDITORY',
  baseRange: { min: 20, max: 20000, unit: 'Hz' },
  enhancementFactor: 2.5,
  safetyMargin: 0.9
});

// Calibrate perception
const calibration = calibratePerception({
  modality: 'TACTILE',
  sensitivity: 0.8,
  resolution: 100,
  adaptationRate: 0.5
});

// Prevent overload
const protection = preventOverload({
  currentIntensity: 85,
  threshold: 90,
  recoveryTime: 500
});

console.log(enhanced.newRange);
console.log(calibration.isCalibrated);
```

### CLI Tool

```bash
# Classify sensory enhancement
wia-aug-004 classify --modality visual --type augmentation

# Enhance modality
wia-aug-004 enhance --modality auditory --factor 2.5

# Calibrate perception
wia-aug-004 calibrate --modality tactile --sensitivity 0.8

# Check overload protection
wia-aug-004 protect --intensity 85 --threshold 90

# Map cross-modal
wia-aug-004 map --from visual --to auditory

# Integrate multiple senses
wia-aug-004 integrate --modalities visual,auditory,tactile
```

## 🌈 Sensory Enhancement Categories

| Modality | Normal Range | Enhanced Range | Enhancement Factor | Use Cases |

6. **Cross-Modal Safety**: Preventing interference between different senses
7. **Neural Plasticity Monitoring**: Tracking brain adaptation to new inputs
