3D Virtual Assistant AI for Astronauts

🚀 Overview

The 3D Virtual Assistant AI for Astronauts is an advanced AI-powered system designed to assist astronauts in space missions by providing real-time voice interaction, facial animations, and intelligent responses. This system integrates AI Large Language Models (LLMs), Python FastAPI, React, Three.js, and Text-to-Speech (TTS) to create an immersive and interactive experience.

🏗️ Tech Stack

• Frontend: React, Three.js (WebGL-based 3D rendering)
• Backend: Python (FastAPI for API handling)
• AI Models: LLMs (OpenAI, LLaMA, or Custom GPT)
• Voice Processing:
  • Speech-to-Text: OpenAI Whisper, Google STT
  • Text-to-Speech: Google TTS, Amazon Polly, OpenAI TTS
• Facial Animation: BlendShapes (Viseme synchronization with speech)
• Database: PostgreSQL, MongoDB (for conversation history & user preferences)
• Deployment: Docker, AWS/GCP/Azure

🎯 Features

✅ 3D Realistic Human Assistant – Built using Three.js & Blender models
✅ Real-time Speech Recognition – Converts astronaut commands into text using AI
✅ LLM-Powered Conversation – Provides intelligent responses using LLM APIs
✅ Text-to-Speech (TTS) Synthesis – Generates lifelike voice responses
✅ Lip Sync & Facial Animations – Enhances realism using Viseme-based animation
✅ Multi-Platform Support – Works on Web (React), Desktop (Unity), and Mobile (React Native)
✅ Space Mission Integration – Provides mission status updates & real-time alerts
