Description

A Method of Embedding Dark Patterns in Layout

technical field

The invention belongs to the technical field of printing and typesetting, and in particular relates to a method for embedding dark lines in a layout.

Background technique

For a long time, people have been developing how to transmit or connect electronic information with paper media, such as the relatively mature barcode technology, as shown in Figure 2. Now, Japan has launched a mobile phone that can directly recognize barcodes, and then can use it to realize the connection from magazines to the Internet; major express companies at home and abroad have adopted two-dimensional barcodes to manage logistics, enabling people to track items on the Internet the shipping status of . Our country has also applied two-dimensional barcode technology in the office field, implementing more secure management of various official documents.

However, as a way of cross-media connection, barcode technology has obvious defects. One is that the information capacity is limited, and the current capacity of the two-dimensional barcode is about 1KB; the other is that continuing to increase the complexity of the barcode will lead to the complexity of scanning and identification equipment, and the cost will be greatly increased; the third is that the location of the barcode must be found when scanning items , it is not convenient to use; Fourth, a large number of barcodes are piled up on the item packaging, which will damage the aesthetics of the item package and interfere with human reading. It is difficult to achieve the effect of "invisibility" in information-intensive publications, and it is also difficult to Present or connect richer multimedia information in a limited layout.

Another type of "reading machine" that seems to be related to paper media multimedia technology actually relies on machines other than books to perceive the coordinates input by users, and manually maintains the strict alignment between books and machines. Strictly speaking, such technologies do not add any information to paper media. Its disadvantage is that it must be equipped with a relatively bulky coordinate board or receiving device, which is not easy to carry, and cannot solve the problem of synchronous page turning well.

In recent years, the international community has focused on the following three aspects:

First, continue the idea of barcodes and continue to explore possible marking forms. Print the barcode directly on the blank space of the paper as described above. Regardless of one-dimensional or two-dimensional, although it is possible to establish a simple connection of some multimedia data, barcodes often damage the beauty of the page when users require greater information expression. Therefore, some researchers continued the idea of barcodes, designed and implemented some simple graphic codes, which can obtain good interactive effects in some specific environments.

Second, the human-computer interaction environment built with augmented reality and pattern recognition technology

PaperLink (Arai, T., Aust, D., Hudson, S.: PaperLink: A Technique for Hyperlinking from Real Paper to Electronic Content, Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, pp.327-334, 1997) is a An earlier system that linked a camera device with a pen and paper, which was able to record manual markings and convert them into electronic content. Technologies such as Interactive Paper, PADD (Paper Augmented Digital Documents), Insight Lab, and LivePape can all be regarded as extended paper interfaces (Augmented Paper Interfaces), that is, to record and output physical paper or desktop, and perceive it through the "vision" of the computer The user's actions on the paper. Drive file operations or capture information based on the interaction of the user's finger, pen, or a series of gestures with the paper. In the past, these technologies needed to limit paper to a plane, but the newly proposed Paperwindow can be used in three-dimensional space, depicting a more humane digital paper simulation environment.

The downside of such methods is that they are still exploratory and rely on complex camera or scanning equipment.

Third, represent and arrange data with fine patterns

The "active form" proposed by Nakagawa uses a special fine pattern as the border of the table, uses the direction and combination of tiny slashes to represent data, and uses them to isolate the data handwritten by the user so that the device can analyze it adaptively and recognition (Shimamura, T., Bilan Zhu, Masuda, A., Onuma, M., Sakurada, T., Nakagawa, M.: A Prototype of an Active Form System, Proceedings of the Seventh International Conference on Document Analysis and Recognition, pp .921-925, 2003). The "DataGlyph" proposed by David L. Hecht also uses slashes "\" and "/" to record data. See the document "Printed Embedded Data Graphical User Interfaces" (IEEE Computer, March 2001). The length, width, and color of the page can be used to synthesize graphics and even images, in order to achieve the purpose of recording a large amount of information without destroying the appearance of the page. In terms of not damaging the page, Koichi Kise also proposed another method to record more information. This method is to record data by printing a fine dot matrix on the blank background of the page. Several dots form a unit. Different arrangements in the area can constitute different coded information, and these points appear smaller compared with the text on the page, so as to reduce their interference to human reading (Kise, K., Miki, Y., Matsumoto, K .: Stippling Data on Backgrounds of Pages-Toward Seamless Integration of Paper and Electronic Documents, Proceedings of the Seventh International Conference on Document Analysis and Recognition, pp.1213-1217, 2003).

However, it is not easy to apply obscurity to the actual publishing and printing field. People usually do it as follows:

1. For dark lines such as barcodes whose dark lines are not fine enough, people mainly use the blank area of the publication layout to lay information, and manually paste the dark picture on the blank area, which is inefficient and cannot achieve the effect of synchronizing the dark lines with the content .

2. For fine dark lines that do not interfere with human reading, in order to achieve the effect of synchronizing with the content, it is necessary to manually select a large number of dark picture pictures, and use manual alignment to place the dark lines in a suitable position.

The production efficiency of the above method is low, which hinders the development and application of dark pattern technology to a certain extent, and also limits the cross-media connection of paper media.

Contents of the invention

In view of the defects in the prior art, the purpose of the present invention is to provide a method for embedding dark lines in the layout, which can solve the problems that the embedding of dark lines cannot be synchronized with the corresponding content and the low efficiency of manual embedding, and does not affect the printed matter. The beauty of the text does not interfere with people's reading.

In order to achieve the above purpose, the technical solution adopted by the present invention is: a method for embedding dark lines in a layout, comprising the following steps:

a. Unified numbers for all dark grain units;

b. Establish the corresponding data table of dark pattern unit and character or character string, described character string is word or sentence;

c. Select the target content to add the dark grain unit, issue the command to add dark grain, the typesetting system will automatically search the corresponding data table to see if there is a dark grain unit corresponding to the content, if not, end the processing, if yes, then Automatically add a dark pattern mark to the target content, and mark its corresponding dark pattern number;

d. The typesetting system automatically calculates the typesetting area of the current target content according to the dark pattern mark, and fills the typesetting area where the target content is located with the corresponding numbered dark pattern unit;

e. The typesetting system generates a PS file, that is, a page description language file, and the dark pattern information is written into the PS file.

Further, the character string includes numbers, Chinese characters, Chinese words, English letters and English words.

Further, in step c, when the selected target content corresponds to multiple dark pattern units, the user selects, and then marks the content and marks its corresponding dark pattern number.

Further, in step d, after marking the target content with a dark pattern, when the typesetting system sends out the typesetting system, first lay the blank code on the entire layout, and then replace the blank code with the corresponding dark pattern unit, and the blank code is A shaded unit that does not point to any character or string is specified by the user or the system.

Furthermore, when replacing, the blank codes on the left edge and the upper edge of the typesetting area are respectively replaced with isolation codes. The isolation codes are dark pattern units that do not point to any characters or character strings, and are specified by the user or the system.

Further, in step d, when adding the dark pattern, the dark pattern corresponding to the character is embedded in the layout area of each character in units of characters. Or, taking a word as a unit, a dark pattern corresponding to the word is embedded in the layout area of each character in the word. Or, taking a sentence as a unit, embedding a dark pattern corresponding to the sentence in the layout area of each character in the sentence.

Further, the dark grain unit is formed of 10-20 fine dots, preferably 16 fine dots. When filling the typesetting area where the target content is located with the corresponding numbered dark grain unit in step d, the size of the filled dark grain unit is between 0.8mm*0.8mm and 1.5mm*1.5mm, preferably 1.35mm*1.35mm . The printing accuracy during printing is greater than or equal to 1200dpi.

Further, the dark grain unit is a picture in BMP format. In step e, the picture in the BMP format of the dark grain unit is converted into a picture in the EPS format of the spot color space, and then the dark grain unit is output in the PS file output. On the spot color version.

The effect of the present invention is that: by adopting the method described in the present invention, the dark pattern can be automatically embedded in the correct position in the layout, and the position can be either a blank area in the layout or an area with content. And it will not damage the aesthetics of the layout after printing. This facilitates the cross-media connection of publications. The method of the present invention can be applied not only to the field of publishing and printing, but also to the field of logistics, etc. The invisible label made according to the method of the present invention can conveniently and quickly realize the distribution of articles.

Detailed ways

Below in conjunction with accompanying drawing of description and specific embodiment, the present invention is further elaborated:

Example 1:

As shown in Figure 1, a method for embedding dark lines in a layout includes the following steps:

(1) Unified numbering for all dark grain units;

In this embodiment, the dark pattern to be embedded is Clevercode (smart code). Clevercode is the most refined and concealed dark pattern in the graphic expression of the dark pattern unit in the current research. It consists of 16 fine patterns in total of 4*4 The dots are arranged in an area of about 1.35mm*1.35mm according to a certain arrangement, and different dark patterns can be produced according to different arrangements of the dots. At present, 65536 different dark patterns (or dark pattern units or dark pattern pictures) can be formed ), its number is: 0-65535, and the file format of the dark pattern is a BMP image. When printing with ordinary carbon-containing ink, the accuracy is greater than 1200dpi, which can be recognized by existing recognition equipment, and the printed dark lines are difficult to distinguish with the naked eye.

(2) Establish a data correspondence table between dark pattern units and character strings (characters, words or sentences).

The specific number of the dark grain units can be determined according to the needs of users. In this embodiment, 65536 dark pattern units of Clevercode, 21003 characters encoded by GBK and 26000 commonly used English words establish a dark pattern corresponding data table. For the spare dark pattern unit, the user can create a data table corresponding to the custom content and the dark pattern number according to the needs;

(3) Select the target content to add dark lines, select the command to add dark lines, and the typesetting system automatically retrieves the data correspondence table;

In this embodiment, the English word "China" is embedded in the Clevercode dark pattern unit, first select "China", issue the command to add dark patterns, and the typesetting system automatically retrieves the corresponding data table,

1) If there is no dark pattern unit corresponding to "China" in the data correspondence table, the typesetting system will not process it;

2) If there is a unique dark-grain unit corresponding to "China" in the data correspondence table, the typesetting system will automatically mark it with a dark-grain mark and mark its corresponding dark-grain unit number;

For the dark pattern corresponding data table created by the Clevercode dark pattern unit, sometimes a character string corresponds to more than two dark pattern units. When the typesetting system retrieves more than two corresponding dark pattern units, the typesetting system prompts the user to make a choice. For example, adding a dark pattern to "￥", the typesetting system retrieves two corresponding dark pattern units: No. 196 (corresponding to RMB) and No. 197 (corresponding to Japanese Yen). At this time, the system prompts the user to select "RMB" or "Japanese Yen". ", the user selects RMB, then marks No. 196 dark pattern unit; selects Japanese Yen, then marks No. 197 dark pattern unit.

At the same time, for polyphonic characters, the dark pattern corresponding data table established by the Clevercode dark pattern unit allows users to mark the corresponding dark pattern unit to be added by selecting the required pronunciation.

(4) In order to make the printed layout have the same gray scale, the typesetting system arranges the entire typesetting area from the starting point coordinates into meaningless blank codes, which are similar to other Clevercode dark pattern units The dark pattern picture is a dark pattern unit that does not point to any character or character string, and is specified by the user or the system.

(5) The typesetting system calculates the typesetting area of "China" according to the dark mark made in step (3). Firstly, the coordinates of the starting point of the first character "C" recorded by the program is the starting point of the typesetting area; the height is the character height, which is determined by the font size; The coordinates of the upper left corner of the layout area and the width and height of the layout area. When "China" does not fit in a line and needs to be changed, the system will mark the position where the line needs to be changed, which is equivalent to dividing "China" into two parts to add the same dark pattern. The first part is the first character of "China". C" to the end of the line, and the second part is the character "a" from the beginning of the line to the end of "China".

(6) The typesetting system replaces the blank codes in the typesetting area with the target dark pattern. At the same time, in order to reduce the interference during hardware recognition, the blank codes on the left edge and upper edge of the typesetting area are replaced by isolation codes. The isolation codes are also Similar to other Clevercode dark pattern units, it is a dark pattern unit that does not point to any character or character string, and is specified by the user or the system.

In this embodiment, a corresponding dark pattern unit is embedded in the typesetting area of each character of the English word "China", and a total of 56 dark pattern units are repeatedly embedded, as shown in FIG. 5 .

(7) The typesetting system generates a PS (page description language) file, and the dark pattern information is written into the PS file;

In this embodiment, the picture in BMP format of the dark texture unit in step (1) is converted into a picture in EPS format of the spot color space, and the dark texture unit is output on the spot color plate when the PS file is output.

(8) After the PS file is interpreted by RIP, the dark grain picture in the printed layout is printed, as shown in Figure 4.

Example 2:

Other steps are the same as in Example 1, the difference is that in step (3), select the target content to add dark lines, select the command to add dark lines, the typesetting system automatically retrieves the data correspondence table, and adds dark lines in units of characters To add, such as: embed the dark pattern unit corresponding to "C" in the typesetting area where the letter "C" is located, embed the dark line unit corresponding to "h" in the typesetting area where the letter "h" is located, and in other i, In the typesetting areas where the three letters n and a are respectively located, dark pattern units corresponding to the three letters are respectively embedded.

When calculating the typesetting area of each letter, the method used is to obtain the width of the corresponding letter from the font library according to the current font and font size, and all the letters have the same height, which is the height of the current line, so that the typesetting of each letter The area can be calculated as character width * character height.

The method described in the present invention has extremely wide applications, for example, it can be used in the field of logistics and used to make invisible labels for various commodities. The relevant information about the commodity can be known through the invisible label on each commodity and the corresponding identification equipment. For example, adopt the method of embedding dark patterns in the layout of the present invention and the smart code described in Embodiment 1, and embed the text below the corresponding text of the relevant materials such as the outer packaging box of the commodity, the product manual, the product certificate, etc. Corresponding dark grain unit. On the one hand, the embedded dark lines do not affect the appearance of these materials and do not interfere with people's reading. On the other hand, through the corresponding handheld identification device, it is possible to identify the dark lines embedded in these materials, and further know the relevant information (text, words, etc.) Send out the voice information of the corresponding characters and words. For example, if a product is a refrigerator, a dark pattern unit corresponding to the word "refrigerator" is embedded in the layout area where the word "refrigerator" is located on the outer packaging box of the refrigerator. When the word "refrigerator" is used, the voice of "refrigerator" will be issued. Of course, the dark pattern unit corresponding to the word "refrigerator" can also be embedded in any other position specified by the user, such as under the picture of the refrigerator on the outer packing box or in other areas.

Since the invisible label composed of high-precision dark grain unit pictures is difficult to distinguish with the naked eye, it can be placed anywhere on the item package, and can be placed under text or pictures without affecting the appearance of the item package; at the same time, it is easy to be identified , There is no need to find the location of the label when reading, as long as it is combined with the identification device, the Internet connection of the item can be well realized, so that the storage of item information and anti-counterfeiting verification can be better realized, and the logistics distribution can be realized conveniently and quickly.

In addition, it can also be seen from the above embodiments that the method of the present invention can be used to embed the desired dark lines in any layout that the typesetting system can output. These dark lines can be related to each character or string in the layout. The corresponding dark pattern can also be a dark pattern defined by the user. Through the handheld identification device, these embedded dark pattern units can be read and identified, and then the characters, character strings (words or characters) corresponding to these dark pattern units can be further obtained through the handheld identification device itself or other information processing devices connected to the handheld identification device. sentences) and emit corresponding sounds, or obtain user-defined pictures, sounds, videos and other information. It is not difficult to imagine that if all kinds of publications in the future adopt the method described in the present invention to embed the smart code described in Embodiment 1, then these publications can solve the problem of reading for the blind by combining hand-held identification devices. People only need to put the hand-held identification device on the pages of these publications, and then send out the corresponding sound information through the hand-held identification device, so that they can know the text content or other information content on the page without looking at them, which will completely solve the blind reading problem. problems, and such publications do not interfere with the naked eye reading of normal people.

Certainly, the method described in the present invention is not limited to the examples described in the specific implementation, for example, the dark pattern unit to be embedded in step (1) can also be other types of dark pattern units, and is not limited to the examples Clevercode mentioned in Clevercode. The specific number of different dark pattern units can be set and produced according to the needs of users, and it is not necessary to produce 65536 different dark pattern units. For the dark grain units arranged by fine dots, the number and arrangement of fine dots in each dark grain unit can also be flexibly set. During typesetting, the size of each dark-grain unit can be flexibly adjusted according to the size of the font. For example, for a large font, the size of the dark-grain unit can be appropriately larger, and for a small font, the size of the dark-grain unit can be appropriately smaller Whether the size is appropriate depends on whether the final printed dark lines interfere with people's reading and affect the appearance of the layout. Of course, those skilled in the art can derive other implementations according to the technical solutions of the present invention, which also belong to the technical innovation scope of the present invention.
