We worked closely with Childish Gambino and his music video choreographer, Sherrie Silver, to make sure the Playmoji’s dance moves rival those of Childish Gambino himself. By using ARCore’s motion tracking, light estimation, and ability to understand the real world, his Playmoji looks and feels lifelike, whether he’s in front of you or in a selfie next to you. He even reacts to your facial expressions in real time thanks to machine learning—try smiling or frowning in selfie mode and see how he responds.
