<Background and Purpose of Development>
Usually, live delivery using 3D models requires large equipment and physical space (studio, etc.), and the delivery itself is a large undertaking due to the need for staff and other resources. With “Niji3D,” using the iPhoneX's Face Tracking with ARKit (face recognition used in the NijiSanji app) and the Oculus Touch controller for the Oculus Rift, it is now possible for a single person to easily deliver a realistic 3D presentation.
