Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques fail to create the illusion that a stationary physical object is moving, despite successfully achieving this effect for displayed objects on screens.
Innovation Solution
A system comprising an image generation device, an object generation device, and a video presentation device, where luminance varying areas are created along the contour of a stationary object's area on a screen, with their luminance varying based on the object and background luminance, to match the object's contour and create the illusion of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If luminance varying areas are provided along two facing sides of a stationary object area on a screen, then the illusion that the stationary object is moving is given, but the technique does not work for physical objects that actually exist in space
Solution Approach 1:
A video presentation device displaying a stationary object area with luminance varying areas is introduced as an intermediary between the actual physical object and the observer. The video presentation creates a visual illusion that combines with the real object to produce the moving illusion effect, enabling the technique to work for physical objects that exist in space.
Solution Approach 2:
A contour-matching stationary object area is created on the video presentation device that copies the outline shape of the actual physical object. This contour matching ensures that the luminance varying areas in the video presentation align with the physical object's boundaries, enabling the illusion effect to be applied to physical objects.
2Measurement precision
If the luminance of luminance varying areas is varied with time to create movement illusion, then the illusion effect is enhanced, but the system complexity increases
Solution Approach 1:
The luminance of the luminance varying areas is varied periodically with time in a predetermined pattern. This periodic variation creates a rhythmic visual effect that enhances the movement illusion while using a simple, repeatable control pattern that does not require complex control systems.
Solution Approach 2:
The luminance parameter of the luminance varying areas is changed with time to create the movement illusion. By controlling only the luminance parameter while keeping other parameters constant, the system achieves enhanced illusion effect with minimal complexity increase.
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 system effectively gives the perception that a stationary physical object is moving by synchronizing the luminance variations with the object's contour on the screen, enhancing the illusion of movement.
Implementation Method 1
luminance of the luminance varying area varies with time in a luminance range based on luminance of the object and luminance of the background area

AI summary
A feeling is given that a stationary object that actually exists as a physical object is moving. In an illusion showing system including: an object; and a video presentation device that presents video for superimposition that includes a stationary object area having a substantially identical contour as a contour of the object, at least one luminance varying area located along a contour of the stationary object area, and a background area other than the stationary object area and the luminance varying area, and in which luminance of the luminance varying area varies with time in a luminance range based on luminance of the object and luminance of the background area, the object and the video for superimposition are shown so that a contour of the stationary object area of the video for superimposition presented by the video presentation device substantially matches a contour of the object.
