Length visual illusion experimental instrument and use method thereof

Abstract

The invention relates to a length visual illusion experimental instrument and a use method thereof. The experimental instrument comprises a bottom shell with a semi-circular structure; the two side surfaces of the bottom shell are provided with a transparent plate and a side plate; the inner side surface of the transparent plate is rotationally provided with a movable plate; the movable plate is fixed relative to the transparent plate through a positioning pin; the movable plate is provided with a through strip-shaped groove opening; the movable plate located on the two sides of the strip-shaped groove opening is provided with guide blocks; the two guide blocks are jointly provided with a suction strip, so that the suction strip moves relative to the movable plate along the guide blocks; atest board is mounted between the movable board and the side board; the test board comprises a first test board and a second test board with a pure color; and the first test board is provided with aplurality of black line segments in the radial direction. A testee observes a strip-shaped sticker on the transparent plate and the test board penetrating out of the strip-shaped groove opening, subjectively judges the consistency of the length, and compares the length with the actual length to obtain the influence of parallel illusion, angle interference and color on vision judgment, thereby displaying the miraculous effect and charm of visual illusion.

Description

technical field [0001] The invention relates to the technical field of visual testing experimental instruments, in particular to a length optical illusion experimental instrument and a method for using the same. Background technique [0002] Optical illusion refers to the wrong judgment and perception based on empiricism or improper reference when people observe certain objects. There are many types of optical illusions, such as color optical illusions, motion optical illusions, geometric optical illusions and so on. Optical illusions are widely used in physics, ecology, architectural design, product design and traffic safety. [0003] Parallel line segment length illusion is a kind of visual illusion, that is, two horizontal parallel line segments of equal length are usually visually perceived as the upper line segment being longer. Previous studies have also shown that the perception of shape is often inseparable from the influence of color, and color will affect people'...

AI Technical Summary

Problems solved by technology

Previous studies have also shown that the perception of shape cannot be separated from the influence of color, and color will affect people's visual perception of objects; the smaller the wavelength of the color of the upper line segment, the less obvious the length illusion

[0004] In the prior art, there is still a lack of a comprehensive demonstration device for optical illusions that can be clearly observed, effectively distinguished, and can generate interactions.
