+# MrrrMe - Privacy-First Smart Mirror for Multi-Modal Emotion Detection
+
+**18-Week Specialization Project | Breda University of Applied Sciences**
+
+A privacy-first smart mirror system that performs real-time multi-modal emotion recognition combining facial expressions, voice tonality, and text sentiment analysis with conversational AI capabilities.
+
+---
+
+## Project Overview
+
+**Program**: AI & Data Science - Applied Data Science  
+**Institution**: Breda University of Applied Sciences, Netherlands  
+**Duration**: 18 weeks (February - June 2026)  
+**Current Status**: Week 7 of 18 (11 weeks remaining)
+
+### Problem Statement
+
+Traditional emotion recognition systems suffer from single-modality limitations, high latency, privacy concerns, and inability to detect masked emotions. MrrrMe addresses these challenges with a comprehensive multi-modal approach.
+
+### Solution
+
+A privacy-first, multi-modal emotion detection system that:
+- Fuses facial expressions (40%), voice tonality (30%), and linguistic content (30%)
+- Processes everything locally with no cloud dependencies
+- Achieves sub-2-second response times
+- Generates empathetic, context-aware conversational responses
+- Integrates with customizable 3D avatars for natural interaction
+
+---
+
+## Key Features
+
+### Multi-Modal Emotion Fusion
+- Weighted fusion algorithm combining three modalities
+- 4-class emotion model: Neutral, Happy, Sad, Angry
+- Confidence-based conflict resolution
+- Event-driven processing for 600x efficiency improvement
+- Quality-aware dynamic weight adjustment
+
+### Facial Expression Analysis
+- Face detection using OpenCV Haar Cascade
+- Emotion recognition using ViT-Face-Expression (FER2013 dataset)
+- 70-75% baseline accuracy on facial expressions alone
+- Real-time processing with quality scoring
+- Efficient frame sampling (5% of frames processed)
+
+### Voice Emotion Recognition
+- HuBERT-Large model for emotional prosody detection
+- Voice Activity Detection with 72.4% processing efficiency
+- Sub-50ms inference per audio chunk
+- 76.8% accuracy on voice-only emotion detection
+- Smart silence detection to reduce unnecessary processing
+
+### Natural Language Understanding
+- Whisper (distil-large-v3) for accurate speech-to-text transcription
+- DistilRoBERTa for contextual sentiment analysis
+- Rule-based overrides for common phrases
+- Conversation memory across sessions
+- Multi-turn dialogue support
+
+### Conversational AI Integration
+- Groq Cloud API with Llama 3.1 8B Instant model
+- Dual personality modes: Empathetic Therapist and Action-Focused Coach
+- Emotion-aware response generation
+- 1-2 second LLM response times
+- Configurable response styles: brief, balanced, detailed
+
+### Avatar System
+- Customizable 3D avatars using Avaturn SDK
+- Realistic lip-sync with Coqui XTTS v2 TTS engine
+- 16 supported languages including English and Dutch
+- Emotion-driven facial expressions
+- Male and female voice options (Damien Black, Ana Florence)
+
+### Web-Based Interface
+- Modern React/Next.js 16 frontend with TypeScript
+- Real-time WebSocket communication
+- Apple-inspired design system with light/dark mode
+- Responsive layout for desktop and mobile
+- Session-based authentication with SQLite backend
