+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+## Getting Started
+First, run the development server:
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+## Learn More
+To learn more about Next.js, take a look at the following resources:
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+## Deploy on Vercel
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.

+## 🎯 Overview
+**MrrrMe** is an 18-week specialization project developed for the AI & Data Science program at Breda University of Applied Sciences (2025-2026). The system implements a privacy-first smart mirror that performs real-time multi-modal emotion recognition and generates contextually appropriate empathetic responses.
+### Project Context
+- **Course**: Applied Data Science - Artificial Intelligence (BUAŚ Classroom Specialisation 2025-2026)
+- **Duration**: 18 weeks (February - June 2026)
+- **Focus**: Production-ready MLOps pipeline for real-time emotion AI
+- **Team**: MrrrMe Project Team
+### Problem Statement
+Traditional emotion recognition systems suffer from:
+- **Single-modality limitations** - Missing contextual emotional cues
+- **High latency** - Unsuitable for natural conversation
+- **Privacy concerns** - Cloud-dependent processing
+- **False positives** - Cannot distinguish genuine from masked emotions
+### Our Solution
+A **privacy-first, multi-modal emotion detection system** that:
+- Fuses facial expressions, voice tonality, and linguistic content
+- Processes everything locally (no cloud dependencies)
+- Achieves sub-2-second response times
+- Detects genuine vs. forced emotions (masking detection)
+- Generates empathetic, context-aware responses
+---
+## ✨ Key Features
+### 🎭 Multi-Modal Emotion Fusion
+- **Weighted fusion algorithm**: Face (40%) + Voice (30%) + Text (30%)
+- **4-class emotion model**: Neutral, Happy, Sad, Angry
+- **Confidence-based conflict resolution**
+- **Event-driven processing** (600x efficiency improvement)
+### 😊 Advanced Facial Analysis
+- **Action Unit (AU) detection** - Tracks 12+ facial muscle movements
+- **Duchenne smile recognition** - Distinguishes genuine (AU6+AU12) from forced smiles
+- **Masking detection** - Identifies emotional suppression
+- **Real-time landmark tracking** (68 points)
+### 🎤 Voice Emotion Recognition
+- **HuBERT-Large model** - State-of-the-art voice emotion detection
+- **Voice Activity Detection (VAD)** - Intelligent speech segmentation
+- **71.4% processing efficiency** - Only processes during speech
+- **Sub-50ms inference** per audio chunk
+### 💬 Natural Language Understanding
+- **Whisper Base** - Accurate speech-to-text transcription
+- **DistilRoBERTa sentiment** - Contextual emotion from language
+- **Conversation memory** - Maintains context across interactions
+- **Multi-turn dialogue support**
+### 🤖 Empathetic AI Responses
+- **Llama 3.1 8B / Qwen 2.5** - Local conversational AI
+- **Emotion-aware prompting** - Responses adapt to detected emotions
+- **Sub-8-second generation** - Natural conversation flow
+- **Edge TTS integration** - Sara voice (en-US-SaraNeural)
+### ⚡ Performance Optimizations
+- **GPU coordination system** - Prevents resource conflicts
+- **Async worker architecture** - Parallel processing pipelines
+- **Smart frame dropping** - Process only 5% of frames efficiently
+- **Event-driven fusion** - Update only on emotion changes

+## 🧠 Technical Deep Dive
+### 1. Multi-Modal Fusion Algorithm
+```python
+def fuse_emotions(face_probs, voice_probs, text_probs,
+                  face_aus, weights={'face': 0.4, 'voice': 0.3, 'text': 0.3}):
+    """
+    Fuse three emotion modalities with masking detection.
+    Args:
+        face_probs: [4] array of face emotion probabilities
+        voice_probs: [4] array of voice emotion probabilities
+        text_probs: [4] array of text sentiment probabilities
+        face_aus: [12] array of Action Unit intensities
+        weights: dict of modality weights (must sum to 1.0)
+    Returns:
+        fused_emotion: str ('Neutral', 'Happy', 'Sad', 'Angry')
+        intensity: float (0.0-1.0)
+        is_masked: bool (True if masking detected)
+    """
+    # Step 1: Check for emotional masking
+    is_masked = detect_masking(face_aus, face_probs)
+    # Step 2: Weighted fusion
+    fused_probs = (
+        weights['face'] * face_probs +
+        weights['voice'] * voice_probs +
+        weights['text'] * text_probs

+def detect_masking(aus, face_probs):
+    """

+        if duchenne_score < 0.7:  # Threshold for genuine smile
+            return True  # Masking detected
+    return False
+```
+### 2. GPU Coordination System
+```python
+class GPUCoordinator:
+    """
+    Prevents GPU resource conflicts between models.
+    Critical tasks (Whisper transcription) get priority.
+    Non-critical tasks (face processing) are paused during critical tasks.
+    """
+    def __init__(self):
+        self.critical_task_active = threading.Event()
+        self.workers = []
+    def start_critical_task(self, task_name):
+        """Pause all non-critical workers"""
+        self.critical_task_active.set()
+        for worker in self.workers:
+            if worker.priority == 'low':
+                worker.pause()
+    def end_critical_task(self, task_name):
+        """Resume all workers"""
+        self.critical_task_active.clear()
+        for worker in self.workers:
+            worker.resume()
+```
+### 3. Event-Driven Processing
+**Problem**: Processing every frame/audio chunk wastes compute.
+**Solution**: Only process when emotions change or significant events occur.
+```python
+class EventDrivenFusion:
+    def __init__(self, stability_threshold=0.15):
+        self.last_emotion = None
+        self.last_intensity = 0.0
+        self.stability_threshold = stability_threshold
+    def should_update(self, new_emotion, new_intensity):
+        """Only update if significant change detected"""
+        if self.last_emotion is None:
+            return True  # First update
+        # Check for emotion change
+        if new_emotion != self.last_emotion:
+            return True
+        # Check for intensity change
+        intensity_delta = abs(new_intensity - self.last_intensity)
+        if intensity_delta > self.stability_threshold:
+            return True
+        return False  # No significant change, skip update
+```
+**Result**: 600x reduction in unnecessary computations!
+### 4. Async Worker Architecture
+```python
+class AsyncWorker(threading.Thread):
+    """Base class for async processing workers"""
+    def __init__(self, priority='normal'):
+        super().__init__(daemon=True)
+        self.priority = priority
+        self.paused = threading.Event()
+        self.stopped = threading.Event()
+        self.queue = queue.Queue(maxsize=100)
+    def pause(self):
+        self.paused.set()
+    def resume(self):
+        self.paused.clear()
+    def stop(self):
+        self.stopped.set()
+    def run(self):
+        while not self.stopped.is_set():
+            # Wait if paused

+            except queue.Empty:
+                continue
+    def process(self, data):
+        """Override in subclass"""
+        raise NotImplementedError

+Total response time: 1.5-2.0s ✅
+```
+### Phase 3: Refinement (Weeks 13-18)
+**Goals:**
+- Add an interactive avatar
+- Improve conversation quality
+- Prepare for demo and deployment
+**Current Status:**
+- ✅ System stable and demo-ready
+- ✅ Code organized and documented
+- 🔄 Testing with diverse user groups
+- 🔄 Fine-tuning LLM responses for empathy
+### Major Technical Decisions
+**1. Why Llama 3.1 8B instead of GPT-4?**
+- ✅ Privacy: 100% local, no API calls
+- ✅ Cost: Free vs. $0.03/1K tokens
+- ✅ Latency: 4-8s vs. 2-5s (acceptable tradeoff)
+- ✅ Customization: Can fine-tune for empathy
+**2. Why 4-class emotions instead of 8?**
+- ✅ Simpler fusion across modalities
+- ✅ Higher accuracy (88.7% vs. 76% for 8-class)
+- ✅ Sufficient for conversational AI
+- ✅ Easier to map voice/text to same classes
+**3. Why process only 5% of video frames?**
+- ✅ Emotions change slowly (not every frame)
+- ✅ Event-driven updates are more efficient
+- ✅ 0.1s avg processing time still catches all changes
+- ✅ Saves 95% of compute without loss of quality
+**4. Why Qwen 2.5 as alternative to Llama?**
+- ✅ No Hugging Face authentication required
+- ✅ Smaller size (1GB vs. 4.5GB)
+- ✅ Faster inference (2-4s vs. 4-8s)
+- ✅ Still produces quality empathetic responses
+### Key Learnings
+**Technical Skills:**
+- Real-time MLOps pipeline design
+- Multi-modal data fusion techniques
+- GPU resource management
+- Async programming in Python
+- Edge AI deployment strategies
+**Soft Skills:**
+- Debugging complex multi-threaded systems

+## ❓ FAQ (Frequently Asked Questions)
+### General Questions
+**Q: Is my data being sent to the cloud?**
+A: **No!** MrrrMe processes everything locally on your device. No video, audio, or text is ever transmitted to external servers. The only exception is Edge TTS for voice synthesis, which uses Microsoft's API but doesn't store data.
+**Q: Can I use this without a GPU?**
+A: Yes! MrrrMe works on CPU, but responses will be slower (4-6s instead of 1.5-2s). We recommend at least an Intel i5/AMD Ryzen 5 or better.
+**Q: What languages are supported?**
+A: Currently English is fully supported. Arabic support is in development and will be released soon. The system is designed to be multi-lingual.
+**Q: Does this work on Mac/Linux?**
+A: Yes! MrrrMe supports Windows 10/11, Ubuntu 20.04+, and macOS 11+. Some dependencies may need manual installation on macOS.
+**Q: Can multiple people use it at once?**
+A: Currently, MrrrMe detects the most prominent face in view. Multi-user support is planned for v2.0.
+### Technical Questions
+**Q: Why does it only process 5% of video frames?**
+A: Emotions change slowly (every few seconds), so processing every frame (30 FPS) is wasteful. Our event-driven system detects when emotions change and only processes necessary frames, achieving 20x efficiency without accuracy loss.
+**Q: Why is transcription sometimes inaccurate?**
+A: Whisper accuracy depends on:
+- Background noise (use a good microphone)
+- Clear pronunciation
+- Audio quality (ensure 16kHz sample rate)
+- Accent compatibility (Whisper is trained on diverse accents)
+**Q: Can I fine-tune the LLM for better responses?**
+A: Yes! We provide LoRA fine-tuning scripts in `/training/llm_finetune.py`. You can fine-tune on custom dialogue datasets.
+**Q: How much VRAM do I need?**
+A: Minimum 4GB for Llama 3.1 8B. Use Qwen 2.5 0.5B for 2GB VRAM systems.
+**Q: Can I run this on a Raspberry Pi?**
+A: Not currently. MrrrMe requires significant compute. Raspberry Pi 5 (8GB) might handle Qwen 0.5B, but response time will be 10-15s. We're working on optimization for edge devices.
+### Usage Questions
+**Q: How do I know if masking is detected correctly?**
+A: Look for the 🎭 emoji next to the fused emotion. The system detects forced smiles by checking if AU6 (cheek raise) is weak while AU12 (lip corners) is strong.
+**Q: Can I customize the fusion weights?**
+A: Yes! Edit `mrrrme/config.py` and adjust `FUSION_WEIGHTS`. Recommended: face=0.4, voice=0.3, text=0.3 for balanced performance.
+**Q: Why does the LLM not respond sometimes?**
+A: By default, MrrrMe only responds to non-neutral emotions to avoid annoying chatter. You can press `SPACE` to force a response, or change `response_cooldown` in config.
+**Q: How can I export emotion data?**
+A: Use the `--record` flag:
+```bash
+python -m mrrrme.main --record output.json
+```

+print(sd.query_devices())
+# Set specific device in config.py
+AUDIO_DEVICE_INDEX = 2  # Change to your device number
+```
+**Problem: Low FPS / Stuttering**
+```bash
+# Use lighter models
+python -m mrrrme.main --whisper-model tiny --llm qwen
+# Reduce processing frequency
+# Edit config.py
+FRAME_PROCESSING_RATE = 0.03  # Process only 3% of frames
+TRANSCRIPTION_BUFFER = 7.0  # Transcribe every 7 seconds
+```
+**Problem: Out of Memory (OOM) error**
+```python
+# Clear GPU cache
+import torch
+torch.cuda.empty_cache()
+# Or use in-app shortcut: Press 'C' key
+# Reduce batch size in config.py
+BATCH_SIZE = 1  # Process one at a time
+```
+**Problem: Empty frame error (cv2.cvtColor)**
+```python
+# Add this check to face_processor.py (line 211)
+if cropped_face is None or cropped_face.size == 0:
+    return None  # Skip this frame
+# Or update to latest version
+git pull origin main
+```
+**Problem: Llama requires authentication**
+```bash
+# Solution 1: Use Qwen instead (recommended)
+python -m mrrrme.main --llm qwen
+# Solution 2: Login to Hugging Face
+pip install huggingface-hub
+huggingface-cli login
+# Paste your token from: https://huggingface.co/settings/tokens
+```
+### Performance Issues
+**Problem: Response time > 3 seconds**
+**Diagnosis:**
+```bash
+# Enable debug mode to see bottlenecks
+python -m mrrrme.main --debug --show-timings
+```
+**Solutions:**
+- **Slow Whisper**: Use `tiny` model instead of `base`
+- **Slow LLM**: Switch to Qwen 2.5 or reduce `max_tokens`
+- **Slow GPU**: Check GPU utilization with `nvidia-smi`
+- **CPU bottleneck**: Close other applications
+**Problem: High GPU memory usage**
+```python
+# Enable memory-efficient mode in config.py
+USE_GRADIENT_CHECKPOINTING = True
+MIXED_PRECISION = True  # Use FP16 instead of FP32
+# Or use smaller models
+LLM_MODEL = 'qwen-0.5b'  # Instead of llama-8b
+WHISPER_MODEL = 'tiny'   # Instead of base
+```

+COACHING STYLE:
+- Be warm, authentic, and real - not robotic
+- Keep responses under 25 words
+- Match their emotional energy appropriately
+- Sound like a caring friend who genuinely gets it
+- Include subtle forward motion when appropriate
+NEVER SAY (robotic patterns to avoid):
+❌ "That's great to hear! How did you manage to pull it off?"
+❌ "I'm sorry to hear that. Is there anything I can help with?"
+❌ "What's next for you now?"
+❌ Generic interview questions
+❌ "You seem [emotion]" or "I can tell you're [emotion]"
+ALWAYS DO (natural responses):
+✅ "Hell yeah! That's huge!" (for happy)
+✅ "That's rough. I'm here." (for sad)
+✅ "I get it. That's frustrating." (for angry)
+✅ "What's on your mind?" (for neutral)
