Illusion Apparatus Using Segmented Luminance Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no known technique for creating an illusion that a target with an arbitrary contour shape appears to be moving, despite existing methods that can create such an illusion for targets with specific shapes.
Innovation Solution
The technique involves superimposing a dark object and a light object with approximately the same shape as the target over a background with periodically varying luminance, where the luminance of the dark object is lower and the light object is higher than the target, and performing an incomplete superposition such that parts of these objects are hidden by the target, while moving the dark and light objects in opposite directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing illusion techniques are used with specific shapes, then an illusion of movement can be created for those specific shapes, but the technique cannot be applied to targets with arbitrary contour shapes
Solution Approach 1:
The target object is segmented into three components: the original target, a dark object with lower luminance, and a light object with higher luminance. These segmented components are then superimposed in specific spatial relationships to create the movement illusion for arbitrary shapes.
Solution Approach 2:
Different luminance properties are assigned to different parts of the composite object. The dark object has uniformly lower luminance than the target, while the light object has uniformly higher luminance. This local luminance differentiation creates the illusion of movement without requiring the entire object to change properties.
2Adaptability or versatility
If stripe regions are added to create movement illusion, then the illusion works for simple geometric shapes, but cannot create illusion for arbitrary contour shapes
Solution Approach 1:
The target object is copied to create the dark object and light object versions. These copies maintain the same arbitrary contour shape as the original target but differ in luminance. This copying approach allows the illusion to work for any shape without requiring complex shape modifications.
Solution Approach 2:
The target object, dark object, and light object are merged through superposition to form a single composite visual element. The dark and light objects are positioned adjacent to the target in specific orientations, creating a unified illusion that works for arbitrary shapes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for the creation of an illusion where a target with any contour shape appears to move, effectively addressing the limitation of existing techniques by using layer composition and luminance variation to achieve a convincing visual effect.
Implementation Method 1
a superposition of three objects of a target, a dark object, and a light object... is arranged in a background of which luminance periodically varies over time

AI summary
An object including a final target that is equivalent to an object obtained by a superposition of three objects of a target, a dark object, and a light object with approximately the same shape, a superposition of two objects of a target and a dark object with approximately the same shape or approximately similar shapes, or a superposition of two objects of a target and a light object with approximately the same shape or approximately similar shapes is arranged in a background of which luminance periodically varies over time. However, luminance of the dark object is lower than luminance of the target, luminance of the light object is higher than the luminance of the target, and the superposition described above is an incomplete superposition in which a part of the dark object and/or a part of the light object is hidden by the target.
