Brief report – 2nd Version




This is a mid-term design report from the group of Paradox and Illusion project, the group members are QIAN Xicheng, KURNIAWAN Anselmus krisma adi, YANG Bingxi, SUBIA VALDEZ Rafael, NIKOLAKOPOULOU Vasiliki and HU Yiang. To deal with the project, the group members have done a series of theoretic research about various types of paradoxes and illusions. This report contains results of our first stage research, which can be separated in 3 parts: Illusions’ information, design description and evaluation.


Definition and Principles

Visual illusions:

Moire effect is the appearance, when two regularly spaced sets of lines are superimposed, of a new set of lines (moiré pattern) passing through the points where the original lines cross at small angles(Encyclopedia Britannica, 2008). The reason why moire pattern is caught by our eyes results from the way in which people interpret visual sense: “the perceptual magnification of small stimulus differences” (Spillmann, 1993, p303). In a moire pattern animation (shown in the demonstration video), the change of moire patterns is so fast and pronounced, while the grating just slightly moves. Therefore, the moire patterns stand out and become strong stimuli which are easy to be recognized by the human mind.

Simultaneous effect is of paramount importance to all who are concerned with color(Johannes Itten, 1970). Simultaneous contrast identified by Michel Eugène Chevreul refers to the manner in which the colors of two different objects affect each other. The effect is more noticeable when shared between objects of complementary color(Hazel Rossotti, 1985). For example, when a light color is surrounded by a dark color, it looks brighter than it actually is.

Design Description

There are several optional forms of the studio project about paradox and illusion.

Option 1: Interactive Installation.

The installation will display in a room with projection and painted panels. Certain designed images are projected on the wall with panels in front, and when audience passed by, the Moire Pattern illusion would appear. To go our research further, we combine another visual illusion, Simultaneous Contrast, to Moire Pattern. We will observe and experiment how color blending effects visual sense based on the illusions’ combination, which is a new area that few people have ever done a similar research previously. In addition, a proper sonic effect will help audience feeling the illusion deeply.



Option 2: Digital work based on software




Evaluation & Audience

This work illustrates the relationship between art and science. It also stimulates our project group to research on more possibilities based on the principles of Moire Effect and Simultaneous Effect through experience and research. Besides, the work will calls for a deeper thinking about time, space and interaction.
