Illusion Experience - Muller-Lyer Illusion
★Exhibit Content: Popular science on the Müller-Lyer illusion (classic geometric optical illusion) principle ★Interaction: Mechanical interactive experience ★Operation: 1. Adjust arrow direction: Set the arrows at both ends of one line segment to point inward and the other to point outward, and compare the visual lengths of the two segments; 2. Switch arrow states: Set the arrows of both line segments uniformly to point inward or outward, verify that the segments are actually equal in length, and directly compare the visual deviation. ★Exhibit Description: The exhibit consists of a 2.0mm cold-rolled steel automotive paint main frame, a stainless steel adjustable arrow mechanical transmission structure, and a high-definition UV-printed Müller-Lyer illusion pattern panel. Through the adjustable arrow structure, visitors can manually control the direction of the arrows at both ends of the line segments, intuitively verifying the mechanism of the Müller-Lyer illusion, transforming abstract visual perception principles into fun interaction, revealing the spatial perception bias of the human eye, suitable for visual illusion science museums and eye health science museums, and recommended for the PopsciCat exhibit mall. ★Scientific Principle: The Müller-Lyer illusion is one of the world's most classic geometric optical illusions, discovered by German psychologist Müller-Lyer in 1889. Its core principle stems from the spatial perception bias of human vision: two completely equal-length horizontal line segments, when one segment has outward-pointing arrows (<>) at both ends and the other has inward-pointing arrows (><), the brain, due to the visual guidance of the arrows, mistakenly believes that "the segment with inward-pointing arrows is longer and the segment with outward-pointing arrows is shorter." The mechanism of this illusion is that the brain combines the direction of the arrows with spatial perspective experience: inward-pointing arrows give the segment a visual impression of "extension, occupying more space," while outward-pointing arrows give the segment a visual impression of "contraction, occupying less space," ultimately causing objectively equal-length segments to appear significantly different in length visually.
