This AR project is an interactable installation, the real/physical iPad will set on a pedestal, the audience should pick it up to see the real-time rendering of the physical environment and there will be several virtual/ augmented iPads showing up behind the camera. The structure of this augmented sculpture is an invisible chain, and each layer will appear or disappear by moving the physical iPad(which is the AR camera) on the y-axis. Its oscillation is constrained by the AR camera, and it will always facing the center pivot of the AR camera. Each layer has 12 frames delayed effect, which attempted tray aspects of reality beyond visual perception. From multi perspectives, this dynamic form creates the fourth dimension and curved the physical space.
