人类视觉系统使用投射阴影来判断物体的三维布局。这个装置的目的是展示纸材料的深度和透明度的新视觉错觉，这是由传统的光影投射图案引起的。因此，这个装置集中在感性而不是技术方面。照亮目标对象，对象的空间附近变暗以产生对象的阴影的视觉印象。通过控制投射阴影的模糊度和/或对象与其阴影之间的空间距离，引起对象布局的感知变化。观众可以交互式地享受视觉体验，其中纸上的物体和字母感知地漂浮在空中。我们还表明，它是可能的编辑材料外观的真实的对象通过操纵的形状的阴影，一个不透明的彩色纸似乎是一个透明的彩色电影漂浮在空气中。
The human visual system uses cast shadows to judge the three-dimensional layout of an object. The purpose of this installation is to demonstrate novel visual illusions of depth and transparency for paper materials, which is induced by the conventional light projection of cast shadow patterns. Thus, this installation focuses on perceptual rather than technical aspects. Illuminating a target object, the spatial vicinity of the object is darkened to produce the visual impression of a shadow of the object. By controlling the blurriness of the cast shadow and/or spatial distance between the object and its shadow, a perceptual change in the layout of the object is induced. The audience can interactively enjoy visual experiences wherein objects and letters on a paper perceptually float in the air. We also demonstrate that it is possible to edit the material appearance of a real object by manipulating the shape of the shadow; an opaque colored paper appear to be a transparent color film floating in the air.
