Meet Albert Einstein – in digital form! «Digital Einstein» is an AI-powered avatar that communicates as if you were sitting face-to-face with the original. He answers questions, asks follow-ups, reacts to moods, and occasionally surprises visitors with a touch of humor. Behind this digital twin lies a complex system of state-of-the-art technologies developed at ETH Zurich. The system combines multimodal speech processing, generative AI, 3D animation, and real-time visualizations to create a unique interactive experience. Take a seat in our chair, ask Einstein your questions, and discover how current research at ETH Zurich is enabling future technologies for digital characters. Experience firsthand how computer science and artificial “intelligence” merge into a vivid, speaking avatar.
