Summary: "Swinging 3D lamp" is a multiuser and naked-eye three-dimensional (3D) display technique using a common projector and printed media. This technique creates 3D optical illusions of motion parallax by superimposing dynamic luminance patterns on a static two-dimensional image in a real environment. The basic idea involves combining "wiggle stereoscopy," a method of creating 3D images by exploiting motion parallax, with "dynamic luminance projection," a projection technique making static images dynamic. However, in some cases, it does not work well when just combining these methods. This challenge was overcome by adding a depth-of-field effect on the original image. The proposed technique is useful for simple and eye-catching 3D displays in public spaces because of the fact that depth information can be presented on the common printed images and that multiple people can perceive the depth without special glasses or equipment.
