Summary Box: ‘Heavy Rain’ creator debuts ‘Kara’

NEW TECHNOLOGY: David Cage of video game developer Quantic Dream unveiled a new way to simultaneously capture and digitize an actor’s performance ? including voice, face and body.

WHAT’S CHANGED: Unlike the methods used to capture actors’ performances in “Avatar,” Cage said the new technique used about 90 sensors placed on an actor’s face instead of a small camera mounted in front of the actor’s head. It’s also faster, less expensive and requires quiet because the audio and movement are captured together.

THE DEMO: It was shown in the form of a seven-minute non-interactive demonstration titled “Kara.”
