Abstract
The invention relates to a demonstration device generating suspension visual illusions, which consists of a head fixing device, an observation model, a special guide rail for the motion of the model and a background board, wherein the head fixing device is fixed at one end of the guide rail; the observation model is arranged on the special guide rail and can move forwards and backwards; and the background board is fixed at the other end of the special guide rail. The bottom color of the background board is white, the center is provided with a black spot, and the center of the background board and the observation model are positioned at the same horizontal line. When the demonstration device is used, an observer stares at the black spot, the observation model is moved slowly towards the observer, then the observer can see that a suspended 'train' blocks the black spot on the background board, and the observer is closer to the observation board, the suspended 'train' is more larger; by adjusting the distance between two 'train' models, the user finds that the distance is more closer, the suspended 'train' is more larger; and when the user stares at the two 'train' models, the suspended 'train' cannot be seen.
Description
One, technical field
The present invention relates to a kind of apparatus for demonstrating and demenstration method that is used to demonstrate effect optical visual, belong to the experimental demonstration device technical field.
Two, background technology
Britain visual science man Ai Ersaikeer (Al Seckel) visual experiment of having reported a kind of " finger of suspension " in " The Art Of Optical Illusions " of showing.This experiment is that both hands are placed on and about 4 centimetres of eyes fronts, stretch out forefinger by finger tip also keep with eyes at same horizontal line, about 3 centimetres at interval on two finger tips, eyes stare at from more than ten centimetre of wall far away of finger and see, will see the finger of a suspension.To point and shift near face gradually, and can find that the finger that suspends will become big.If stare at finger rather than wall, will this phenomenon can not occur.Above-mentioned achievement in research is being done lecture experiment for the university students and middle school students, and it is very useful perhaps doing scientific popularization work in popular science propaganda education department.But The above results is the artificial result who observes on the one hand, its is can be because of the consistance of the difference of the intensity of observer's sight, bimanual movements different with degree of stability not to observe stable result, on the other hand, only depend on people's moving forward and backward with the hands, can cause the tired out of people's arm.Up to the present, also there are not a kind of Special Equipment that is used to observe and method.
Three, summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of reasonable in design, easy to manufacture, easy to use, can effectively observe the apparatus for demonstrating and the demenstration method that produce suspension visual illusions.
Produce the apparatus for demonstrating of suspension visual illusions, by head fixing device, observe model, the exclusive guideway and the background board that are used for model sport form, head fixing device is fixed on an end of guide rail; Observe model and be installed on the exclusive guideway, can move forward and backward; Background board is fixed on the other end of exclusive guideway.The background board background color is a white, and the center is provided with a stain, and background board center and observation model are on same horizontal line.
Described observer's head fixing device is a stationary installation of the adjustable size joint of person's head according to the observation.The device two ends constitute by regulating crooked material.
Described observation model is made up of model, support and the square groove of two train shapes, and " train " model is rack-mount, and distance can be regulated between two " train " model.
Described exclusive guideway is a kind of line slideway, and length is 40 centimetres, and its cross section is a rectangle, is slightly less than the internal diameter of square groove, can insert in the square groove.
Described background board center is meant on same horizontal line with the observation model, two " train " model height is consistent with the centre-height of background board in the observation model, when the observer observed, by observing model, the stain at background board center was in the center of two " train " model spacing.
Produce the demenstration method of suspension visual illusions, its concrete demenstration method is:
(1) observer is placed on head in the head fixing device, and two sections of regulating devices are fixed head, and two " train " model spacing is transferred to about 3 centimetres, by the centre of two " train " model spacing, keeps a close watch on the stain on the background board.
(2) slowly move towards observer's direction and observe model, can see that a suspension " train " blocked the stain on the background board, it is near more from the observer to observe model, and " train " of suspension is big more.
(3) observer is placed on head in the head fixing device, and two sections of regulating devices are fixed head, and two when keeping a close watch on two " train " model, slowly move towards observer's direction and to observe model, then can not see " train " of suspension.
(4) observer is placed on head in the head fixing device, and two sections of regulating devices are fixed head, and " train " of seeing suspension regulates distance between two " train " model afterwards, finds that distance is near more, and " train " of suspension is big more.
The present invention promptly can be used as experimental demonstration device and the method that effect optical visual is observed, also can be used as a kind of game device and method, make people particularly the teenager in the process of recreation, when strengthening game-play enjoyment, deepened perceptual knowledge to effect optical visual.
