Abstract
We present a multiuser, wide-angle, and naked-eye three-dimensional (3D) display technique called a “swinging 3D lamp.” This technique creates 3D optical illusions of motion parallax by superimposing dynamic luminance patterns on a static two-dimensional (2D) 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 can be difficult to obtain sufficient depth information when combining these methods. This was overcome by adding a depth-of-field (DOF) 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 RGB images of common printed media and that multiple people can perceive the depth without special glasses or equipment.
