Abstract
The utility model discloses a kind of coffee wall illusion demonstrator, comprise base plate, stripe board, pull bar, guide rail; Base plate and stripe board are rectangle, and stripe board is no less than 7 pieces, and along stripe board broadside up and down by being arranged in order, the shape of every block stripe board is identical, and stripe board surface is provided with black bars alternately and white square; The length of stripe board equals the odd-multiple of its width; Every block stripe board to be flexibly connected with base plate by the guide rail of being located at its back side and can to move left and right along stripe board long side direction; Pull bar is fixed on the broadside of every block stripe board.The optical illusion pattern that the utility model can change, can hang on all kinds of scientific and technological venue, by eye observation and hands-on, is conducive to deepening the understanding to optical illusion phenomenon.
Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of optical illusion phenomenon demonstrator, is specially a kind of coffee wall illusion demonstrator.
Background technology
Optical illusion is when people observe some object, the false judgment to the object of observation formed based on empiricism or improper reference and perception.The kind of optical illusion has a lot, as geometry illusion, light and shade illusion, color illusion, shape illusion, illusion of movement, shade illusion etc.Optical illusion all has a wide range of applications in fields such as psychology, physiology, physics, design sciences.Design optical illusion is observed and identification device, is conducive to the content enriching activity to popularize scientific knowledge, excites student to probe into the interest of science secret.
Coffee wall illusion is by a kind of optical illusion of Britain psychologist Richard Gregory Late Cambrian, and in this illusion, one group of parallel lines is subject to the vision interference of the black and white square pattern be dislocatedly distributed between lines, and lines look like uneven.At present, this optical illusion pattern is all the changeless pattern be imprinted on paper, lacks a kind of Special Equipment starting to differentiate this illusion.
Summary of the invention
The purpose of this utility model is the coffee wall illusion demonstrator designing the clear demonstration of a kind of energy and be conducive to illusion resolution.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: comprise base plate, stripe board, pull bar, guide rail; Described base plate and stripe board are rectangle, stripe board is no less than 7 pieces, along stripe board broadside up and down by being arranged in order, the shape of every block stripe board is identical, stripe board surface is provided with black bars and the white square that the length of side equals stripe board width, and black bars and white square are along stripe board long side direction alternately; The length of described stripe board equals the odd-multiple of its width; Every block stripe board back side is provided with guide rail along stripe board long side direction, and stripe board to be flexibly connected with base plate by guide rail and can to move left and right along stripe board long side direction; Pull bar is fixed on the broadside of every block stripe board, for left and right push-and-pull stripe board.
The length of described stripe board is more than or equal to 9 times of its width.
The stroke of described guide rail is more than or equal to the width of stripe board.
Owing to adopting above-mentioned design, the utility model can produce following beneficial effect: utilize the every block stripe board of pull bar left and right push-and-pull, black bars (or white square) corresponding in neighbouring stripe board is made dislocation to occur and do not line up, the lines be now made up of the long limit of each piece of stripe board seem it is uneven each other, form optical illusion thus.Use each stripe board of pull bar left and right push-and-pull again, make the square pattern consistency from top to bottom in each stripe board, now the lines that form of the visible long limit of each stripe board are parallel to each other, carry out the resolution of illusion thus.The optical illusion pattern that the utility model can change, can hang on all kinds of scientific and technological venue, by eye observation and hands-on, is conducive to deepening the understanding to optical illusion phenomenon.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is formation schematic diagram of the present utility model (when forming optical illusion pattern).
Schematic diagram (when black bars and black bars consistency from top to bottom) when Fig. 2 is the utility model discriminating optical illusion.
Schematic diagram (when black bars and white square consistency from top to bottom) when Fig. 3 is the utility model discriminating optical illusion.
In figure: 1. base plate, 2. stripe board, 3. pull bar, 4. guide rail, 21. black bars, 22. white square.
Embodiment
As shown in Figure 1, the utility model comprises base plate 1, stripe board 2, pull bar 3, guide rail 4; Base plate 1 and stripe board 2 are rectangle, stripe board 2 is no less than 7 pieces, along stripe board 2 broadside up and down by being arranged in order, the shape of every block stripe board 2 is identical, stripe board 2 surface is provided with black bars 21 and the white square 22 that the length of side equals stripe board 2 width, and black bars 21 and white square 22 are along stripe board 2 long side direction alternately; The length of stripe board 2 equals the odd-multiple of its width; Every block stripe board 2 back side is provided with guide rail 4 along stripe board 2 long side direction, and stripe board 2 to be flexibly connected with base plate 1 by guide rail 4 and can to move left and right along stripe board 1 long side direction; Pull bar 3 is fixed on the broadside of every block stripe board 2, for left and right push-and-pull stripe board 2.
The length of described stripe board 2 is more than or equal to 9 times of its width.
The stroke of described guide rail 4 is more than or equal to the width of stripe board 2.
See Fig. 1, utilize the every block stripe board 2 of pull bar about 4 push-and-pull, make black bars 21 corresponding in neighbouring stripe board 2 dislocation occur and do not line up, the lines be now made up of the long limit of every block stripe board 2 seem it is uneven each other, form optical illusion thus.
See Fig. 2, by the every block stripe board 2 of pull bar about 4 push-and-pull, make black bars 21 in every block stripe board 2 all consistencies from top to bottom, now the lines that form of the visible long limit of each stripe board 2 are parallel to each other, carry out the resolution of illusion thus.
See Fig. 3, by the every block stripe board 2 of pull bar about 4 push-and-pull, white square 22 in one piece of stripe board 2 is above alignd with the black bars 21 in one piece of stripe board below, and now the lines that form of same visible each long limit of stripe board 2 are parallel to each other, carry out the resolution of illusion thus.
