Description

Visual illusion demonstration device

Technical Field

The invention relates to an optical illusion demonstration device, which is an optical science and technology exhibit used in a science and technology museum and belongs to optical education instruments.

Background

Visual illusions refer to a particular perception of disagreement with objective facts that are formed based on perceptual experience, inappropriate reference, or the like, as a person or animal observes an object.

Understanding the principles of optical illusion first must understand the formation of visual effects. When light reflected by an external object carries information on the surface of the object to pass through the cornea and aqueous humor, the light enters the eyeball from the pupil and is focused on the retina to form an object image. The object image stimulates the photoreceptor cells on the retina, and nerve impulses generated by these photoreceptor cells are transmitted along the optic nerve to the visual center of the cerebral cortex, i.e., the occipital lobe portion of the cerebral cortex, where the nerve impulses are converted into a view recognized in the brain. The generation of the scenes is processed, and the scenes are in cooperative work of 'angle feeling', 'image feeling', 'three-dimensional feeling', and the like, and the images are restored in a brain virtual space according to the shot information, and the restoration is equal to the outward projection of the images. The virtual position can be roughly aligned with the original physical position, which is the scene we see.

Any visual information that our eyes provide to us is usually ambiguous and the information provided by itself is not sufficient to allow us to give a definite interpretation of real world objects. In fact, there are often a number of different interpretations that are believed to be different. It is however noted that only one interpretation can be made at a time, and that no mixed-up singularity of several interpretations occurs. The different interpretations of the visual image are illustrative of what is mathematically called an "ill-posed problem". There are many possible solutions to any one ill-posed problem that are equally justified without the addition of any information. To obtain a true solution, mathematically so-called "constraints" need to be used. The vision system must derive inherent assumptions on how best to interpret the input information. Our common sense of sight is that there is no uncertainty as to what we are looking at, since the brain combines together the information provided by many salient features of the visual scene, such as shape, color, motion, etc., and gives the most reasonable interpretation of all these different visual cues when taken together.

The object is not easy to be found in the background with the same or similar color, the front part and the back part of the yellow and blue squares are respectively in the gray background and the same color background at the same time in the process of simultaneously advancing the two squares, the front end of the motion direction is obviously observed, the eyes can clearly catch the motion of the square, the other square looks static, the processes are staggered, and the staggered visual illusion of the motion and the static is generated through the active judgment of the brain, as shown in figure 10. At present, the visual illusion is displayed through media and is not displayed through a real object.

Disclosure of Invention

The invention aims to solve the technical problem that the visual illusion video is converted into an entity form, so that the magic phenomenon which can be observed only through two eyes can be actually operated, the interactivity and the interestingness are enhanced, and related concepts, principles and the like are popularized to audiences better.

In order to solve the problems, the invention provides a demonstration device for showing visual illusion to the public, which comprises a main body and a display stand, wherein the main body comprises an outer barrel, a lower barrel and an upper barrel, and the display stand comprises an infrared motion detection trigger, a control circuit and a rotary table. The outer barrel is made of transparent organic glass material, is positioned on the outermost layer and is connected with the exhibition table surface, and the other parts except the observation area are pure white. The lower cylinder is made of transparent organic glass material and is positioned between the outer cylinder and the upper cylinder, the cylinder opening is upwards arranged on the rotary table, a limiting cylinder is arranged in the cylinder, and four groups of small blue-yellow squares are attached to the upper half part of the lower cylinder. The upper barrel is made of transparent organic glass material, is positioned at the innermost layer, is provided with a limiting hole and is installed downwards to sleeve the limiting barrel of the lower barrel; the upper barrel is divided into an upper part and a lower part, the upper half part of the upper barrel is adhered with dark stripes, and the lower half part of the upper barrel is a gray background; the upper barrel is provided with a handle, and the upper barrel can be lifted through the handle, so that the blue and yellow small blocks move in the dark stripes and the gray background.

Compared with the prior art, the invention has the advantages that the optical illusion in the media is actually displayed in front of the audience in a mechanical simulation mode, and the audience can interactively operate and experience the optical illusion phenomenon more intuitively.
