Researchers now scan a person's face to build a photorealistic 3D avatar that mimics their expressions in real time for telepresence.
Digital humans scan a real person's face and body to build a realistic 3D model, then drive its expressions and movements in real time using motion capture or AI trained on how faces naturally move. This lets the avatar mimic subtle expressions closely enough to feel lifelike, whether for video calls, customer service, or film.

Earlier photorealistic faces often fell into the 'uncanny valley,' feeling unsettling rather than convincing, and recent progress in digital humans has focused on smoothing those subtle imperfections.
