Illusion Experience - Jastrow Illusion
★Exhibit Content: Popular science on the principle of the Jastrow illusion (classic geometric size optical illusion) ★Interaction: Mechanical interactive experience ★Operation: (1) Compare the sizes of the upper and lower panels; (2) Rotate the panels to change their positions, and then compare which panel appears larger? ★Exhibit Description: The exhibit consists of a square tube skeleton + 2.0mm cold-rolled steel automotive paint main frame, acrylic high-definition UV-printed double sector rings + serrated decorative pattern panels, rotating transmission mechanism + anti-slip operating handle, etc. It is a recommended exhibit for the KexMall exhibit mall. Through the rotatable mechanical structure, visitors can personally control the position of the sector rings and intuitively verify the principle of the Jastrow illusion. ★Scientific Principle: The Jastrow illusion refers to the optical illusion where two curves of equal length, with the lower one appearing longer than the upper one; similarly, two identical sector rings, with the lower one appearing larger than the upper one. The Jastrow illusion is a classic geometric size optical illusion discovered by American psychologist Jastrow. Its core principle stems from the human eye's spatial contrast and curvature perception bias: two completely equal-length curves (or two identical sector rings), when surrounded by an arc-arranged serrated decorative ring, the lower sector ring, due to visual contrast, curvature guidance, and spatial filling effects, causes the brain to mistakenly perceive it as 'larger and longer than the upper sector ring'.
