Abstract

PROBLEM TO BE SOLVED: To obtain a means which arouses the psychological action not dependent upon the symbols (characters and meaning graphics) requiring learning with a meaning transmission means using visual stimuli. SOLUTION: This device has a structure combining a lenticular lens array 4 and zebra patterns 3 having arbitrary pitches and has the effect of generating optical beat patterns 6. As an observer 5 moves, these beat patterns 6 are visible as if the patterns move in a direction backward from the moving direction of the observer 5 or in a forward direction. The observer 5 is psychologically aroused of the deceleration or acceleration action by such effect.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a state change of an observer,
Also, the present invention relates to a display device that generates a visual flow pattern in which a display pattern changes in response to a change in the surrounding environment.

[0002]

2. Description of the Related Art When an arbitrary meaning is directly transmitted to a person, a method of projecting a visual pattern such as a sign, a character, and an image, a method of using an auditory stimulus such as voice or music, and a method of producing a Braille. The method can be broadly divided into a method using a representative tactile stimulus. In particular, visual communication plays a role of most of the means of communication in modern society without being compared with other means of communication due to the large amount of information and the speed of transmission.

[0003] There are various forms and methods for transmitting meaning by this visual stimulus. Some of the above-mentioned conventions, such as the above-mentioned symbols and letters, consist of a display pattern that follows the learning items.The installer of this pattern who wants to convey his intention and the observer who wants to read the meaning communicate with each other. There are many common ways of communicating based on common recognition and knowledge. Specific examples include books and traffic signs. These achieve the meaning transfer by acquiring knowledge called learning. In addition, this learning mode and level can be classified into more detailed forms, but will not be described further here.

As another form of means for transmitting meaning by visual stimulus, a meaning transmission method using an abstract expression, such as a picture or a photograph, that is, an image can be included in the meaning transmission by visual stimulus. This evokes a psychological sensation based on experience, and can transmit meaning without requiring learning in advance. For example, things that are used for the purpose of communicating occupations and business types, such as car pictures and vegetable pictures on signs, etc., and visual indications called pictograms and isotypes with simple and easy-to-understand designs that slightly abstract the form and emphasize the features and so on.
Pictograms are installed mainly in places where people from different languages, such as international conferences and exhibitions, gather to gain common recognition, semantic communication, and guidance, and various excellent designs have been proposed. Some of them have become international standards and are used, for example, for emergency exit guidance signs.

[0005] There are also paintings, such as paintings, that express aesthetic sensations or express what the creator intends, specifically or abstractly. These, as described above, are not for understanding by learning, but for raising cognitive understanding based on experience, such as seeing and knowing cars and vegetables.

[0006] Images can be further classified into several types, such as still images, moving images, and three-dimensional images, according to their modes. However, from the viewpoint of exerting an action of evoking a psychological sensation without requiring learning, It is considered the same, and detailed description is omitted. In addition, there are many things that combine the characteristics of symbols and images, such as subtitled movies and decorated character designs.

Further, several forms can be seen in the display means for visually transmitting an arbitrary meaning in response to the state or environment of the observer. There is known a structure in which a display pattern changes depending on a position where an observer stands or an observation angle with respect to display. As shown in FIG. 4, the lenticular lens array 1 has a light condensing function and a plurality of display patterns 2 divided in the generatrix direction of each lens of the lenticular lens array 1. The display pattern 2 is a lenticular lens. The display pattern 2 is arranged in parallel with the array 1 so that the distance (substrate thickness) is substantially equal to the focal length of each lenticular lens, and the display pattern 2 is obtained by dividing 2 or 3 images into a number of strips. As shown in FIG. 5 (3), it is stuck alternately. It has a structure in which two image patterns (1) and (2) in the figure are installed for each divided strip. The lenticular lens and the array pitch of the image divided into strips are defined so that the focus of each lenticular lens is focused on any one image when viewing the entire display structure from an appropriate observation place. From the viewpoint of the previous observation, only one image pattern is apparently extracted and displayed. When the display is moved while maintaining the distance from the display in the direction perpendicular to the generatrix of the lenticular lens array 1 and the display is viewed, the focal position of each lenticular lens is aligned with the next or another image strip, and in an instant The whole display image is replaced with another image. When the display returns to the original observation position, the apparent display image returns to the original position.

This display can change its display content in response to the observer's position and observation angle. In other words, the most distinctive feature is that the display structure does not unilaterally transmit the contents to be displayed to the observer but has a structure depending on the state (position, angle) of the observer.

This display mode can be installed semi-permanently without exchanging energy, even if the display is variable, to obtain the effect.

[0010]

However, in the above-mentioned means for directly transmitting arbitrary meaning to a person, in particular, in the method of projecting a visual pattern such as a symbol, a character, and an image, the former is used. The two require learning in order to understand this, and cannot understand things outside the scope of learning, such as those related to foreign languages and different cultures, and cannot communicate or read intentions. In the latter image, the atmosphere of the entire display and the direct image of the subject itself can be quickly understood, but there is a limit in accurate transmission of information, and there is a tendency to emphasize one-sided scenes. Further, there is a problem that time is required for creation and image processing, and it takes time to transmit information in total.

In the case of pattern display, particularly in the case where the display pattern (image) is switched depending on the state (observation position) of the observer, the image is switched only at that observation position and can be used as observation position information. Since the number of screens is limited, it is difficult to obtain sufficient accuracy as position information.
Furthermore, the state does not correspond to the moving speed of the observer, and the state of the observer cannot be read from the display pattern for other operations.

The present invention solves the above-mentioned problems, and the display pattern changes continuously in response to the state or change of the observer. It is another object of the present invention to provide a visual flow pattern generator that does not require energy supply for display.

[0013]

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is directed to a substantially planar zebra pattern comprising a row of a plurality of staggered lines each having an arbitrary width and arranged substantially linearly and substantially parallel to each other. A plurality of focal lengths each having an optical axis perpendicular to a generatrix parallel to each line direction of this zebra pattern,
And a visual flow pattern generator comprising a lenticular lens array having lenticular lenses having the same arrangement pitch, wherein a distance between the zebra pattern and the lenticular lens array is set to a substantially focal length of the lenticular lens, and A visual flow pattern generator, wherein the relationship between the arrangement pitch of the lenticular lens array and the arrangement pitch of the light and shade lines of the zebra pattern is 4: 1 or more irrespective of the focal length of the lenticular lens. When the display pattern is observed from the observer by adopting such a configuration, a light and shade pattern having an arrangement pitch larger than the arrangement pitch of the lenticular lens array is observed, and the pattern display is perpendicular to the observer's pattern display. Apparent in response to movement in direction In which a light pattern is observed to move to the opposite direction of the direction of the movement.

According to a second aspect of the present invention, the substantially planar zebra pattern has a plurality of concentric circle area patterns, and the lenticular lens array has an optical axis and a focal point at the center of the concentric circle pattern having a positive refractive power. This is a visual flow pattern generation device characterized by having a configuration that replaces a circular area lens with the camera. By adopting such a configuration, it can respond not only to the left and right directions but also to the vertical movement of the observer. In other words, the light and shade pattern is apparently observed to move in the direction opposite to the direction of the movement.

(Embodiment 1) FIG. 1 is a main partial view for explaining Embodiment 1 of the present invention. The principle of the visual flow pattern generator according to the first embodiment of the present invention will be described with reference to FIG. The lenticular lens array 4 includes a zebra pattern 3 designed in the vertical direction on the paper and a lenticular lens array 4 having a generatrix along the zebra pattern disposed at an arbitrary distance, and the arrangement is such that an observer is located ahead of the optical axis of the lenticular lens. . The focal lengths of the lenticular lenses are equal to each other, and the focal lengths are substantially equal to the distance between the zebra pattern 3 and the lenticular lens array 4. Therefore, when an arbitrary lenticular lens array 4 is observed from an observer 5 with a sufficient distance, the entire surface becomes a dark color or a light color of the zebra pattern 3 and is projected to the field of view. When the viewpoint position of the observer 5 is further moved along the direction in which the lenticular lens array 4 is arranged, the convergence position of each lens on the lens having the observer as the object point is parallel to the movement direction of the observer 5, and Move in the opposite direction. This convergence position moves from the dark portion or the light portion of the zebra pattern 3 to the adjacent portion, and the lenticular lens array 4 looks as if the observer 5 has receded.

When the entire lenticular lens array 4 is viewed from the position of the observer 5, a light and shade pattern having a pitch larger than the arrangement pitch of the lenticular lens array 4 is observed. This can be regarded as an apparent beat pattern 6 caused by a slight deviation between the pitch of the convergence position of the lenticular lens array 4 and an arbitrary integral multiple of the density pitch of the zebra pattern 3 as shown in the figure. The pitch of the beat pattern 6 is such that the smaller the deviation, the larger the pitch, and the larger the deviation, the smaller the pitch. When the observer 5 moves, the beat pattern 6 also moves apparently. This moving direction is determined by the sign of the difference between the integral multiple of the pitch of the zebra pattern 3 and the convergent pitch. If this is positive, the beat pattern 6 appears to move along the observer's movement direction, and if negative, the beat pattern 6 moves in the opposite direction to the movement direction.

FIG. 2 is an overall view for explaining the first embodiment of the present invention. Further, the effect of the apparent movement of the beat pattern 6 on the observer 5 will be described with reference to FIG. In the same figure, when the beat pattern 6 moves in the opposite direction with the movement of the observer 5 (Va) (Vb), the observer 5 usually recognizes his / her own movement, excluding acceleration / deceleration felt by the body. It is generally dominant to observe the flow of the surrounding scenery visually. It is natural, but the side view seems to have moved backward by the amount I moved. However, in the light-fluid pattern generator of the present invention, the beat pattern 6 observed with the movement of the observer 5 moves the observer 5 (Va).
In the opposite direction (Vb), the observer's own speed of movement around the lenticular lens array is faster than the actual one, and the visual and psychological cognitive speed Vs is The difference between the moving speed Va of the observer 5 and the flow speed Vb of the beat pattern is Va − (− Vb) = Va + Vb. By feeling your own moving speed faster than it actually is, for example, if you need to slow down the car due to traffic safety, you can usually write “slow down!” Or a traffic sign (speed limit) in sentences. Is notified to the driver (observer), and the driver recognizes this and moves to a deceleration operation. However, both text and symbols need to be learned, slowing down people such as foreigners who can not read the text and those who do not learn enough symbols (such people will not drive, but are tired) There is a possibility that the operation may fall into a dangerous state such as a delay.

According to the light flow pattern generation device of the present invention, learning is not required, and the apparent peripheral pattern moving speed perceived by the observer appears to be accelerated, so that deceleration can be naturally induced. In particular, it can be installed semi-permanently without the need for energy supply to achieve the effect.

(Embodiment 2) FIG. 3 is an overall view (perspective view) for explaining Embodiment 2 of the present invention. The operation of the visual flow pattern flowing device according to the second embodiment of the present invention will be described with reference to FIG. 2 is a cross-sectional view taken along a two-dot chain line in the top view. In the top view in the same figure, a two-dimensional area lens 7 as an upper structure is shown on the left side. On the right side, a concentric circle area pattern 8 as a lower structure is shown. In the sectional view, the hierarchical structure of the two-dimensional area lens 7 and the concentric area pattern 8 is shown. The operation will be further described. In the figure, an observer (not shown) observes a concentric area pattern 8 having substantially the same diameter as the condensing lens as a whole through a two-dimensional area lens 7. Each condensing lens has the same diameter as each other and has a focal length substantially equal to the distance between the condensing lens and the concentric area pattern 8. Has the effect of projecting by expanding it over the entire condenser lens. The density pitch viewed from the center of the concentric circle area pattern 8 is an arbitrary integral multiple thereof and the arrangement pitch of the condenser lens is slightly shifted, so that a beat pattern appears on the whole. Is a mottled pattern (not shown) as a whole, and the display pattern appears to flow in response to not only the back and forth movement of the observer but also the up and down movement, and evokes the psychological effect described in the first embodiment. Is what you can do.

[0021]

According to the light flow pattern generating apparatus of the present invention, no learning is required, and the apparent pattern moving speed of the surroundings perceived by the observer appears to be accelerated, so that the deceleration can be naturally induced. In particular, it can be installed semi-permanently without the need for energy supply to achieve the effect. Conversely, traffic congestion caused by deceleration, such as at the entrance of a tunnel, can be reduced.
