Illusion Experience - Ponzo Illusion

Optics & Eye Health

★Exhibit Content: Ponzo Illusion ★Interaction: Mechanical interactive experience ★Operation: 1. Take a look and judge whether the two straight lines below the figure are equal in length. 2. Turn the handwheel and observe what changes. ★Exhibit Description: Through an interactive mechanical structure, the exhibit allows visitors to personally verify the mechanism behind this visual illusion: in the initial state, two metal rods of equal length against a perspective background create a visual bias of "the upper one longer and the lower one shorter"; after turning the handwheel to adjust the position/length of the rods, visitors can intuitively compare the difference between objective length and visual perception, deeply understand that "seeing is not necessarily believing," and reveal the processing limitations of the human visual system affected by experience and perspective. Recommended exhibit for the KexMall exhibit mall. ★Scientific Principle: The Ponzo illusion, also known as the railway track illusion, is a classic geometric optical illusion, referring to two horizontal line segments of exactly equal length that, against a background of a pair of diagonal lines converging into the distance (simulating railway tracks or perspective lines), cause the upper line segment to be perceived as longer. Its core principle stems from the human eye's perspective perception experience: the brain automatically interprets the diagonal lines converging toward the center as "space extending into the distance" based on the perspective rule in life that "railway tracks converge into the distance," and then mistakenly believes that of two horizontal line segments of exactly equal length, the upper line segment (seemingly "far away") is longer than the lower line segment (seemingly "near").
