Description

Information display device

Introduction

The invention relates to an improved apparent-animation device for information display.

The Background of the Art

The WO 98/48401 International Patent Application discloses a device for supplying highway advertising having an advertising board placed near to a public road and containing different advertising elements, mainly text and/or picture elements, in which in front of the broadsheet, in the direction of cars nearing the broadsheet on the road, modifying part(s) freeing and/or covering the advertising elements at least partly is (are) fixed at a distance creating an impression of movement for persons sitting in the cars.

According to the previously cited patent application the essence of the device lies in its making the impression of an apparent movement for a viewer approaching the advertising board by having modifying part(s) covering at least a part of the surface of the advertising board, practically anterior board(s) and the viewer approaching the device has the impression of the displacement of the anterior board in relation to the board arranged behind this anterior board which is naturally only a visual fallacy induced by the anterior board's being nearer to the approaching person than the rear board. The above cited patent application contains an instruction to arrange the board by the side of the highway and that the device provides the required effect when the viewer is moving towards the broadsheet of the device. It is obvious that in general the above mentioned device can also be realized as an apparent-animation device for information display which has basic information display board for the display of visual information having an information display surface which comprises elements of visual information and modifying parts and the advertising board can be realized as a special embodiment of that. This device can also be used e.g. as traffic security signal board for example in such a manner that the arrows signing the direction of avoiding or the strips of a crossing point for pedestrians seem to move in the picture and in this way also attract the attention to the possible danger. The above disclosed device can obviously be used not only arranged near to highways but also near to other kinds of routes.

Here should be mentioned the meaning of some definitions used in this text for explaining and helping the reader understand more easily the expressions used in the further part of the specification.

It is possible that the device is arranged near to a plurality of routes at the same time, but only those routes are relevant to the subject-matter of the invention that have such section(s) that the device has modifying part(s) at least partially freeing and/or covering element(s) of visual information, said modifying parts placed in front of the basic information display board viewed from the direction of the viewer approaching the basic information display board along the said route- sections, arranged at a distance from the basic board that creates an impression of movement for the viewer.

Two different courses can belong to a route and a person on course can move along the given continuous route using any of these two courses especially with regard to its part where the device is arranged. The route can make bends, so the person moving all along it in a given course can approach the device in certain route-sections and in other route-sections can get farther from it during the same trip and there may also be route-sections where the driver neither approaches nor gets farther from the device. So the route has route-sections and one of the two courses can be ordered to them (this is the so-called approaching course) such that the viewer moving along the said route-section in the said course is getting nearer and nearer to the device in a monotone way in accordance with the advance along the route. The route or a continuous part of that can be covered with route-sections contacting each other at their end-points i.e. continuing in each other. According to the definitions used in this application the approaching course is always the same at any point within the relevant route-section. The approaching course of two relevant route-sections contacting each other at their end-points i.e. continuing in each other can be co-directional or reverse within a continuous route. An example of this latter case is the case of appointing the two route-sections in such a manner that their common point is the only point of the route to be positioned nearest to the device, which may be e.g. a point of the curve included by the route. If the possible longest relevant route-section is to be appointed around one part of the route, the end-points of the section should be appointed as far in both directions, as is possible without the turn of the approaching course: in this case a relevant route-section can be appointed which can continue at neither of its end- points in such other relevant route-sections that the approachig courses of the sections are co-directional : in this case the end-points of the appointed relevant route-section can not be crossed over without the turn of the approaching course ordered to the given point of the route. These route-sections are the relevant route- sections for the longest continuous approaching and these are relevant in the case of examining the function of the device.

The Summary of the Invention

An improved embodiment of the information display device according to the invention is formed as a device of increased security. The apparent-animation device known from the instruction of the above mentioned WO 98/48401 International Patent Application can attract the attention of the viewer to itself if it makes the impression of movement, advantageously that of an accelerated movement. However, the text of the cited document does not give any instructions about the angle enclosed by the plane of the basic information display board and the direction of the axis of the route-section passing by it, but its drawings show the basic board in front view from the aspect of the viewer, which means that the basic board of the device is arranged perpendicularly to the direction of the axis of the route. This arrangement really ensures the fairly quick apparent animation as well as makes the device more easily visible from farther, so the aims of the above mentioned specification are completely realized.

However, our recognition lies in that contrary to the cited instruction and technical fore-judgement based on it the perpendicular value of the angle between the basic information display board and the axis direction of the route-section passing by it has been approved in respects newly recognized rather disadvantageous, so the adjustment of the above mentioned angle to other values according to these new respects results in new advantages which have not been recognized yet. By adjusting the above mentioned angle to new values the effect can namely be significantly decreased that the apparent animation effect of the device can detract the attention of the driver in a disadvantageous measure from the traffic. The device can suddenly detract the attention of the persons moving by car in the route- sections of the route near to the device from the traffic in a disadvantageous measure if the apparent movement suddenly appears or accelerates just when the driver gets very near to the device. The sudden, unexpected occurrence of the apparent movement and its direction positioned for the driver very laterally to the course can make together the driver turn suddenly and quickly his/her eyes and attention to a lateral direction, which is extraordinarily dangerous for the participants of traffic. It is safer if the apparent movement appears sooner and begins gradually for the viewer being farther from the device.

The aim relating to this is to make an apparent-animation device of increased security arranged near to the route in an appropriate angle which offers an apparent animation of a speed whose irregularity is acceptable for the viewer moving along the route-section positioned nearest to the device with a steady speed.

According to the results of our examinations the larger the angle between the information display surface of the device and the axis of the route is, the more uneven is the change of the speed of the apparent animation in function of time for the viewer moving in the route-section positioned nearest to the device. From this point of view the perpendicular position is the most disadvantageous of the angles between 0 and 90°. In the case of arranging the basic information display board parallel to the route the apparent animation speed remains steady, but in the case of increasing the above mentioned angle to direction from 0 to 90°, the speed of the apparent animation in function of time gets more and more uneven, which means that there will first be an apparent animation of a speed perceptible for the participant of the traffic only nearer and nearer to the device (and more and more laterally to him her), but in this case the animation accelerates immediately very quickly. In appropriate ways e.g. by means of computational means the very significant increase of the unevenness of the speed of the apparent animation in the case of increasing the above mentioned angle to 90° can definitely be demonstrated. It has been established that the unevenness of the speed of the apparent animation is very significantly decreased by decreasing the above mentioned angle from 90° even with a slightest value. This means that the unevenness of the speed of the movement is already significantly lower in the case of the above mentioned angle being at least somewhat less than 90 degrees than in the case of an angle of 90°. If the angle is 85° or even smaller, this advantageous effect is even more significant.

The angle between the axis of the route and plane of the basic board being about 45° is the most advantageous position from the point of view that it unifies the effects which are advantageous for the viewers staying near to and far from the device.

So the apparent-animation device of increased security is essentially formed as a device for the display of advertisement or other visual information having a basic information display board arranged near to route(s) and provided with an information display surface containing elements of visual information e.g. advertisement elements, preferably text(s) and/or picture(s), the basic information display board being arranged near to one or more continuous relevant route - section(s) being part(s) of some relevant route(s) such that viewed from the viewpoint of a viewer being at any point of the relevant route-section and moving along the full length of the relevant route-section in approaching course and thus getting nearer and nearer to the device as a monotonous function of the viewer's moving along the route, in front of the information display surface otherwise at least partially directly visible for the viewer of the basic information display board, arranged with a space distance providing for the viewer an impression of movement the device has modifying part(s) at least partially freeing and/or covering elements of visual information arranged in the information display surface of the basic information display board, the device according to the invention being such that the smallest positive angle between the plane fitting best to the information display surface of at least one of its basic information display boards, i.e. its basic plane and the tangent line touching the axis of the relevant route being nearest to the device at its point being nearest to the device, i.e. its orientation angle is smaller than 90°.

The advantage of the device realized in this manner in comparison to the known solutions lies in its offering an apparent animation of a speed unevenness acceptable for the viewer moving along the route-section positioned near-by to the device and detracts less the attention of the driver. Further on, its other advantage is that the apparent animation lasts finally longer, which eases the interpretation of the sight. From this point of view it is advantageous if the above mentioned orientation angle is smaller than 85°, more advantageously smaller than 80 or 70° or is under these values. The orientation angle is advantageously larger than or equal to 45° at the same time. Another improved embodiment of the information display device according to the invention can be realized as an approximately dimensionally stable apparent- animation device. According to the instruction of the above mentioned WO 98/48401 International Patent Application the essence of the known apparent- animation device for supplying highway advertising lies in its attracting the attention of the viewer to itself by making the impression of an apparent movement and in which an animation of the highest possible, but at least a minimum speed is necessary for achieving the required effect, for which the highest possible driving speed and biggest possible distance between the modifying part and basic information display board are desirable so that the apparent animation is quick enough, which increases the effect of advertisement in this way.

According to our recignition, however, contrary to the instruction known for the person skilled in the art and technical fore-judges based on this instruction, a certain delimitation of the distance between the modifying part and the basic information display board and its adjustment according to utterly new aspects have advantages which have not been recognized yet, namely in the case of adjusting the distance in a new manner considering the other circumstances of the function of the device the apparent size of the modifying part relative to the basic board i.e. the real size of the surface part in the plane of the basic board covered by the modifying part changes in a significantly smaller measure for the viewer during a single viewing process. This is very advantageous in the case of applications in which the viewer should preferably not recognize that the modifying part is not arranged in the plane of the basic information display board, so the adverse effect in which the picture in the modifying part seems to be enlarged in an appreciable measure, and so the modifying part actually seems to be out of the plane of broadsheet, can be eliminated.

The aim of the invention based on the above mentioned recognition is to realize an apparent-animation information display device properly arranged along the route which has an approximately dimensionally stable apparent animation effect.

The viewer has the impression that the apparent size of the modifying part is equal to the real size of the surface part in the plane of the basic board covered by the modifying part from his/her eyes. In the case of supposing the existence of an essentially planar basic information display board and a planar (e.g. circle plate shaped) modifying part whose plane is displaced at space distance from and parallel with that of the basic board the proportion between the apparent linear size (in the case of the present example the diameter) of the modifying part and its appropriate real linear size (in the case of the present example its diameter) is the same for the viewer being in viewing distance from the plane of the basic board as that between the above mentioned viewing distance and the difference between the said viewing distance and the above mentioned space distance. This means that the viewer has the impression that the modifying part is linearly enlarged in front of the basic information display board, where the linear amplification can be expressed by means of the ration fraction, the counter of which contains the distance between the viewer and the plane of the basic information display board and the denominator of which contains the difference between the above mentioned distance and the distance between the modifying part and the plane of the basic information display board:

lin.am = (distance between the viewer and plane of the basic board) (distance between the viewer and plane of the basic board)- -(distance between the modifying part and plane of the basic board) We recognized that the cause of the animation of a given modifying part being dimensionally unstable in a disturbing measure is that the linear- amplification-values determined by the space distance belonging to the modifying part in the device on the one hand and the typically occurring said viewing- distance-values originated from the correlation between the device and the route on the other hand are included in such a too wide interval that makes the changing of the linear amplification during the relatively short viewing time too conspicuous for the viewer.

So the viewer is not disturbed by the too low or increased measure of the linear amplification, but exclusively by its changing in an excessive measure during the viewing. According to our observations the disturbing effect arises when the rate between the maximum and minimum values of the linear amplification taking place during the viewing is higher than 1.60.

The essence of the recognition relating to the apparent-animation device with an approximately dimensionally stable animation - lies in that it is necessary for achieving the desired approximately dimensionally stable animation effect to determine the rate of 1.60 as the maximum rate between the maximum and minimum values of the linear amplification as a function of the viewing planar distance during the effective viewing of a given device carried out by the viewer. If the manner of arranging the device near to the route is chosen so that it is advantageous for the effect of advertisement and the basic board can also be seen very well relatively far from its plane, it can be supposed that the minimum value of the linear amplification can be supposed to be 1.0. (In the case of a calculation carried out with an accuracy of one decimal figure this situation remains when the viewer can see the basic board from a distance from the plane of the basic board which is 22 times larger than that between the basic board and modifying part, which means in the case of a space distance of 3 metres that the viewer can already see the basic board when in a distance of 66 metres from the plane of the basic board.) On the basis of this supposition the requirement can be concluded that the value of the linear amplification can never be more than 1.60 during the effective view, which exactly means that the viewer during the effective view should stay at least 2.7 times farther from the plane of the basic board than the modifying part.

The picture arranged in the basic information display board can be seen without any aberration in the case of viewing it from a direction perpendicular to the information display surface. In the case of viewing the basic board arranged in a vertical plane from a horizontal direction positioned farther and farther from perpendicular, the height of the picture elements remains the original size while their apparent width decreases and the picture becomes unenjoyably distorted after a while. According to our observations the person viewing the basic board can see the picture elements of the basic board with such low distortion in the case of which the dimensionally stable animation is important when the viewer views at least one point of the information display surface of the basic information display board from a direction perpendicular to the surface or from one that differs at most 45 degrees from perpendicular. So the period of effective view is the period when the view takes place from these effective viewing points.

So the approximately dimensionally stable animation can only be realized when the modifying element is arranged at most at such a distance from the plane of the basic information display board that equals 0.37 times the smallest distance at which the viewer approaches the plane of the basic board while staying within the region of the effective viewing points. As it is known the viewer moves along the route, so the path of the viewer can be approximated very well by the axis of the route.

The approximately dimensionally stable apparent animation device can be realized as a device for the display of advertisement or other visual information having a basic information display board arranged near to route(s) and provided with an information display surface containing elements of visual information e.g. advertisement elements, preferably text(s) and/or picture(s), the basic information display board being arranged near to one or more continuous relevant route- section(s) being part(s) of some relevant route(s) such that viewed from the viewpoint of a viewer being at any point of the relevant route-section and moving along the full length of the relevant route-section in approaching course and thus getting nearer and nearer to the device as a monotonous function of the viewer's moving along the route, in front of the information display surface otherwise at least partially directly visible for the viewer of the basic information display board, arranged with a space distance providing for the viewer an impression of movement the device has modifying part(s) at least partially freeing and/or covering elements of visual information arranged in the information display surface of the basic information display board, the device according to the invention being such that at least one of its modifying parts is arranged at most in a 0.37 times smaller distance from the plane fitting best to the information display surface, i.e. the basic plane than the possible smallest distance between the basic plane and the part of the axis of at least one relevant route-section not continuing at either of its ends in a relevant route-section having the same approaching course as that of the previously mentioned relevant route-section, the part being such that the smallest positive angle between the basic plane and the shortest straight sections connecting the points of the part with the information display surface is at least 45 degrees.

The device realized according to the aboves has the advantage in comparison with the other solutions that it has an apparent dimensionally stable animation effect to the viewer during the effective view period. Further on, the advantage of the device according to the invention lies in its requiring so similar accommodation effect in the eyes of the viewer viewing the basic board and the modifying part which also makes the device appear to be monoplane. If the device should have at least one modifying part formed in the above mentioned manner arranged in a distance from the above mentioned basic plane which is maximum one third, more advantageously one fifth and more advantageously at most one tenth, or even less, of the distance between the above mentioned basic plane and above mentioned part of the axis, the apparent dimensionally stable animation effect can be utilised more effectively.

Further on the apparent dimensionally stable animation effect can be utilised more effectively, if the majority of the above mentioned modifying parts of the device, more advantageously all the modifying parts meet the above mentioned criteria, and it is advantageous if the majority, even more advantageously all of the relevant route-sections not continuing at any of their ends in relevant route-sections having co-directional approaching courses meet the criteria. Additionally, the above mentioned criteria are preferably also fulfilled in such a manner that the possible smallest angle mentioned in the criteria is 30°, but more advantageously only 20°.

A further improved embodiment of the apparent animation device according to the invention is formed as a one-way device. The essence of the device disclosed in the WO 98/48401 International Patent Application lies in that the viewer moving along the route in the so-called approaching course, i.e. thus getting nearer and nearer to the device has the impression that the modifying part is, relative to the background board, moving rightwards when the line of the momentary course of the viewer passes left of the modifying part and vice versa : the modifying part seems to move leftwards when the line of the viewer's course passes right of the modifying part. The above mentioned document contains no instruction about how exactly to arrange the device near to the route, but it is obvious that there are a lot of possibilities all of which ensure the above mentioned apparent animation effect.

Since there is usually a two-way traffic on the most routes, such a situation can occur during the realization of the device that the viewers moving along certain route-sections in the course approaching the device and viewing the device can see that the given animation takes place rightwards while the viewers approaching along other route-sections and viewing the device can see that the same animation takes place leftwards. In the case of certain applications e.g. certain advertising pictures, however, animation only makes sense in one direction and e.g. the sight of an aircraft flying backwards has no good effect of advertisement. This problematic situation can typically occur in the case of certain winding routes or as well in the case of more than one routes positioned near to the device, so near to busy highway junctions, consequently scenes having a high advertising efficiency. The aim concerning this recognition is very important because offers a solution for allowing the installation of apparent-animation devices at the most possible locations, but at the same eliminating the problems caused by reverse animation.

According to our recognition a new and more effective arrangement can be formed considering so far unknown and new points of view and circumstances which can realize the aims very well. Contrary to the technical fore-judgement, the recognition is based on the thought that the harmful effect is not actually caused by a part of the viewers approaching the device being able to see the reverse animation provided they look at the device but the actual harmful effect is caused by several viewers actually watching the reverse animation take place. So a quite new criterion has been composed concerning the improved device.

According to the above the particularity of the apparent-animation device lies in its attracting and keeping the attention to itself due to the apparent movement of its modifying part in comparison to the basic information display board. According to our observation the apparent-animation device attracts the attention of the moving person as soon as the apparent movement of the modifying part takes place for the moving person in front of the information display surface of the basic information display board and then really sustains the attention of the viewer. According to a further recognition the above mentioned apparent movement for attracting the attention should take place on one hand in the peripheral field of view and on the other hand in the so-called visual sphere of action of the device in order that the device can attract the attention of the viewer to itself and engage it.

As it is known, the human eye (and also his/her seeing attention) is focussed in a certain direction at any moment, i.e. the viewing direction and can only see the objects positioned in this direction sharply enough. However, the human eye can perceive certain things (e.g. especially movement) in a certain measure in an angle differing a bit from the angle of view. This process is called peripheral seeing which is possible only when the peripheral sight element is positioned within the peripheral angle of view. The largeness of the peripheral angle of view depends on a plurality of factors (e.g. advancing speed of the person looking in the advancing direction), and can be different for each person and in addition it can be influenced by the size, speed and other features of the peripheral sight elements. According to our observation the largeness of the peripheral angle of view related to the direction of motion for a person moving by car on the highway concerning the perception of the apparent movement induced by the modifying part of the apparent-animation device along the road is between 20 and 45°.

The visual sphere of action of the device is the sphere from within which the viewers can see the device most sharply. Within this sphere the route-section is positioned which is near enough to the device so that the viewers staying along this route-section can see the picture elements arranged in the device sharply enough. According to our observation the advertising and other picture elements arranged in display boards (typically in advertising billboards) are practically detailed to such an extent that the viewers staying not farther from the point of the nearby route which point is positioned nearest to the board than the triple of the width of the board can see the board detailed enough. From farther than this above mentioned distance some details of the picture arranged in the board are not visible any more. Moving off the board, the picture in the board is getting less visible, so the apparent animation has no more importance for viewers approaching the board from a too large distance.

As far as the one-way apparent-animation device is concerned, the main recognition lies in that in order that the device provides the person participating in the traffic with its animation effect, it is necessary for the person participating in the traffic and typically looking in the direction of his/her course to notice that within his/her peripheral field of view the modifying part is in apparent motion in front of the information display surface of the basic board. For the viewer who does not notice this no apparent animation takes place. So in order that for a certain group of the persons moving along the route (in this case, for example, for the group moving along the disadvantageous route-section) there is no apparent animation taking place at the device, it is necessary that within their peripheral field of view during their motion within the visual sphere of action of the device there is no apparent motion of the modifying part taking place relative to the basic board.

So the one-way apparent-animation device is formed as a device for the display of advertisement or other visual information having a basic information display board arranged near to route(s) and provided with an information display surface containing elements of visual information e.g. advertisement elements, preferably text(s) and/or picture(s), the basic information display board being arranged near to one or more continuous relevant route-section(s) being part(s) of some relevant route(s) such that viewed from the viewpoint of a viewer being at any point of the relevant route-section and moving along the full length of the relevant route-section in approaching course and thus getting nearer and nearer to the device as a monotonous function of the viewer's moving along the route, in front of the information display surface otherwise at least partially directly visible for the viewer of the basic information display board, arranged with a space distance providing for the viewer an impression of movement the device has modifying part(s) at least partially freeing and/or covering elements of visual information arranged in the information display surface of the basic information display board, the device according to the invention being such that it has at least one such modifying part, regarding which at least one relevant route has essential points, the essential points being all such points of the axis lines of all the relevant route- sections of the relevant route not continuing at any of their ends in any relevant route-sections having co-directional with theirs approaching courses that are at most at a distance from the nearest point of the relevant route to the basic information display board which distance corresponds to the triple of the width of the information display surface of the basic board and in which points the line of the course does not intersect with the modifying part, and for all such peripheral essential points at which the smallest absolute value of the angles between the vector of the approaching course starting from the essential point on the one hand and the vectors starting from the essential point and pointing to the modifying part on the other hand, i.e. the peripheral view angle, is smaller than 20 degrees the vectors of approaching course starting from the peripheral essential points avoid the modifying part either exclusively from the left or exclusively from the right. The device realized in this way has the advantages in comparison to other solutions that it practically offers at most an apparent animation process of the desired direction to any viewer approaching the device in any course.

For a more advantageous application of the one-way apparent animation the above mentioned conditions should exist on more, preferably all, of the relevant routes arranged near to the device, preferably serving for automobile or other vehicle traffic or other kind of traffic. The said criterions are preferably met also if the said distance is fivefold or more advantageously eight-fold or twelve-fold of the width of the said surface of the basic board or even more from the points of the route positioned nearest to the basic board. The above conditions can also be fulfilled more advantageously in the case of a peripheral angle of view of 25 or more advantageously of 30, 40, 45, 50 or 75°or even more.

Further on, it is advantageous when the majority of the above mentioned modifying parts of the device, but more advantageously all the modifying parts meet the above criteria. Disclosure of the drawing

Fig. 1/1 shows a top- view of the device according to the invention. The subject-matter of the invention is disclosed more detailed on the basis of one drawing No 1/1 showing an advantageous embodiment of the device. The city route is the highway 1, the barrier line of which indicates the axis 2 of the highway. The basic information display board is formed as a broadsheet board 3, arranged in an essentially vertical plane and seated onto the ground. The surface of the broadsheet board is covered by a broadsheet 4 which is the information display surface. The sizes of both the basic information display board 3 and its information display surface 4 are as follows: width w=18 metres and the height is 11 metres. The modifying part 5 is arranged in front of the broadsheet 4 in a plane parallel to that of the broadsheet and in a distance t=3 meters from the broadsheet 4, the upper edge of which is parabolic shaped so that it can also utilise the horizontal apparent animation for achieving vertical effects. The material of the modifying part 5 is metal plate, its surface is covered by a broadsheet, its height is between 3 and 6 metres and its width is m = 4.8 metres.

The device contains a picture planned for an animation taking place rightwards, so the viewer moving by car in the approaching course 6 at the point P of the axis 2 of the highway 1, which point P is at a distance of r = 5 * w = 90 meters from the nearest to the device point R of the highway 1 the point R being at n = 18 meters distance from the device, practically looking in the direction e of his/her own movement, and in the meantime noticing and afterwards going on watching the apparent movement of the modifying part 5 in front of the broadsheet 4, is provided all the time with an animation of proper animation direction (which is rightwards), as his/her course direction always avoids the modifying part 5 from the left i.e. in such a way that the modifying part 5 stays right of the course direction. The viewer moving in course 6 is provided with an animation of a significant speed already well before reaching point Q, the nearest point of the axis 2 of the highway 1 to the device, because the angle (alfa) = 45° between the tangent of axis 2 at point Q and the plane of broadsheet 4 is much smaller than 90 degrees, in fact, it is the ideal 45 degrees. Thus the viewer can also control his/her own attention when arriving quite near to the device.

The viewer arriving by car from the other end of the highway 1 in the opposite course 7 could first perceive animation having arrived in the point S of the axis 2 of the highway 1, because this is his/her first situation when the modifying part 5 seems to be positioned in front of the broadsheet viewed by viewer. At this moment the course of the viewer is the straight line g and he/she should look to the side relative to that in an angle χ=58° in order to view modifying part 5, so the viewer will not begin to view the animation which would seem to be reverse for him her, because the apparent animation taking place in the direction of the straight line f is not within his/her peripheral field of view.

The straight line drawn from the edge of the broadsheet 4 to the point Q encloses a smallest positive angle of (180°-β)=45° with the plane of the broadsheet 4. The axis 2 of the highway 1 approaches the plane of the broadsheet 4 at most in a distance of a=15 metres - this distance is the fivefold of the distance t=3 metres between the modifying part 5 and the plane of the broadsheet 4 - in a geometrical region essential for the dimensional accuracy of the modifying part 5, thus the viewer approaching in course 6 is all the time provided with an approximately dimensionally stable apparent animation.
