We introduce PlayerOne, the first egocentric realistic world simulator, facilitating immersive and unrestricted exploration within vividly dynamic environments. Gi the ven corresponding an egocentric w scene orld and image generate from the egocentric user, PlayerOne videos can that accurately are strictly construct aligned with the real-scene human motion of the user captured by an exocentric camera. PlayerOne is trained in a coarse-to-fine pipeline that first performs pretraining on ing, lar follo ge-scale wed by egocentric finetuning text-video on synchronous pairs for coarse-le motion-video vel egocentric data extracted understandfrom egocentric-exocentric video datasets with our automatic construction pipeline.
