Abstract
We propose a technique to give motion illusions to static paper objects. Previous studies have reported visual
illusions wherein a static “virtual” object apparently moves on the basis of the luminance interaction between
object’s contours and the object’s background. However, no studies have proposed a method to give motion
illusion to a static “real” object. This study found a phenomenon in which a paper objects having bright and dark
contours apparently moved against the background with dynamic luminance modulation. Manipulating the contour
patterns could also produce not only a simple illusory movement such as translation but also relatively complex
illusory movements such as expansion, contraction, and rotation. We call this technique Danswing (Dance +
swing) papers. By utilizing the Dancing papers, it is possible to gather customer’s attention towards an actually
static, but perceptually dynamic, objects.
