Description

  The present invention relates to a document structure template sheet for reproducing document information by a bar code reading / reproducing apparatus, and a document information reproduction system using the document structure template sheet.

  In braille used by a blind person, six dots are used to represent one hiragana character, and a sentence is formed by enumerating such dot patterns. However, in braille, it is difficult to represent kanji and symbols, and the size of one braille is generally limited by a frame of 6 mm × 1 cm, so that the character size cannot be reduced as with normal characters. For this reason, the Braille information requires several times more space on the paper than when represented by normal characters. Therefore, for example, in written examinations such as entrance examinations and qualification examinations, the blind person takes time to understand the problem, and it is necessary to turn many pages to review the problem.

  In Patent Document 1, a number to be input from a keyboard and a braille representing this number are written at a predetermined position of the book, and when the number represented by the braille is input from the keyboard of the information presenter, An information presentation system is disclosed in which the content of the text described in is reproduced by voice. However, with this system, the blind person can read the text next to the braille until he / she inputs the number represented by the braille printed at a predetermined position on the book and plays it as voice. I cannot judge whether it is a sentence that I want.

  The present invention enables a blind person, a learning handicapped person, etc. to grasp a relatively large amount of information described on a sheet in a systematic and easy-to-understand manner in a short period of time, and to obtain necessary information from the barcode reading / reproducing apparatus. An object of the present invention is to provide a document structure template sheet that can be efficiently reproduced through the reproduction function, and a document information reproduction system using the document structure template sheet.

According to the first aspect of the present invention, there is provided a document structure template sheet representing a document structure of document information, the template sheet having a plurality of two-dimensionally partitioned areas on its surface, and components of the document structure And a symbol or Braille indicating the document structure printed in the area of the template paper, and recorded in the area where the symbol or Braille is printed or in the vicinity thereof and recorded corresponding to the symbol or Braille. Detailed information of the document information corresponding to the component of the document structure indicated by the symbol or Braille, and the two-dimensional minimal barcode recorded corresponding to the symbol or Braille Is used to read the two-dimensional minimal bar code and store the symbol or code stored in the bar code reading / reproducing apparatus. Document structure template paper used to regenerate the detailed information of the document information corresponding to the components of the document structure indicated braille is provided.

  In the present invention, not all document information (detailed information) is represented in braille or characters on the template paper, but only the document structure is represented using symbols or braille. Here, the document structure means a document structure having, for example, a document chapter number, chapter heading, section number, section heading, paragraph number of paragraphs constituting the section, and the like as constituent elements. An area on a paper surface (a partitioned area specified by a two-dimensional coordinate position on the paper surface) on which a symbol or a Braille character representing a component of the document structure is printed, or a nearby area is associated with the symbol or Braille. An invisible two-dimensional minimal bar code is printed. Symbols or Braille representing the components of the document structure are associated with detailed information, respectively, and the detailed information is stored in the barcode reading / reproducing apparatus in association with the two-dimensional minimal barcode. Therefore, for example, if a blind person follows a braille with his / her finger while tracing the area where the braille is printed or the vicinity thereof with a barcode reading / playback device, the two-dimensional pattern associated with the character or symbol represented by the braille The barcode reading / reproducing apparatus reads the minimal barcode, and the barcode reading / reproducing apparatus reproduces detailed information associated with the two-dimensional minimal barcode. That is, the detailed information is not described on the template sheet, and only the document structure is represented on the template sheet. For this reason, people with learning disabilities and blind people can grasp the document structure in a short time as a system of information through symbols and braille, and read detailed information efficiently from the place where these symbols and braille are printed. It can be played back through a playback device. If detailed information corresponding to a specific symbol or Braille printed on the template paper is required again, it is not necessary to reproduce all the information and corresponds to a specific symbol or Braille that can be recognized from the document structure. By reading only the two-dimensional minimal barcode, the detailed information corresponding to only the symbol or Braille can be reproduced.

  In the document structure template sheet of the present invention, the two-dimensional minimum barcode may include position information on the template sheet of an area where the symbol or Braille is printed. In the sentence structure template sheet of the present invention, since a plurality of areas specified by two-dimensional coordinate positions are partitioned on the sheet surface, the position of each area on the template sheet is determined as a vertical position (row) or a horizontal position (column). Based on the above, it can be uniquely identified. For this reason, the symbol or Braille printed on the predetermined area of the template paper can be uniquely associated with the position of the area on which the symbol or Braille is printed on the template paper. Therefore, by including the positional information of the region where the symbol or Braille is printed in the two-dimensional minimal barcode printed in the region where the symbol or Braille is printed or in the vicinity thereof, the symbol or Braille, The two-dimensional minimal barcode can be uniquely associated. That is, a person who prints a two-dimensional minimal barcode on a template sheet recognizes the area on which the symbol or braille of the template sheet is printed, and converts the two-dimensional minimal barcode including the position information of the area into the area or What is necessary is just to print in the vicinity area. Further, when the two-dimensional minimal barcode includes position information, the barcode reading / playback apparatus may store the detailed information in association with the position information, and the position information is uniquely identified. The association work with the detailed information is also easy. Furthermore, it is possible to flexibly cope with a change in the printing position of the symbol or Braille due to the modification of the document structure.

  In the document structure template sheet of the present invention, the detailed information may be reproduced as sound. By reproducing the detailed information as a voice through the reproduction function of the barcode reading / reproducing apparatus, the contents of the detailed information can be known even for a blind person, a learning handicapped person with difficulty in character recognition, and an elderly person.

  In the document structure template sheet of the present invention, the symbol or Braille may be printed on the two-dimensional minimal barcode. Since the two-dimensional minimal bar code is invisible, even if a symbol or Braille is printed over it, it does not hinder the learning handicapped person or the blind person from recognizing the symbol or Braille.

  A plurality of two-dimensional minimum barcodes corresponding to the symbol or Braille may be recorded in the area where the symbol or Braille is printed. In this case, most of the two-dimensional minimum barcodes can be read even if some two-dimensional minimum barcodes are destroyed by printing symbols or braille over the two-dimensional minimum barcodes. High reading reliability can be obtained.

  According to a second aspect of the present invention, there is provided a document information reproduction system comprising the document structure template sheet of the first aspect and a barcode reading / reproducing apparatus, wherein the barcode reading / reproducing apparatus is arranged on the document structure template sheet. Corresponds to the position information on the template paper of the area where the symbol or Braille included in the two-dimensional minimal barcode is printed, and the barcode or the Braille that reads the recorded two-dimensional minimal barcode Based on the location information included in the two-dimensional barcode read by the barcode reading unit, the detailed information associated with the location information is retrieved from the storage unit based on the storage unit in which the detailed information to be associated is stored. Then, a document information reproduction system including a reproduction unit that reproduces the detailed information is provided.

  By using the document information reproduction system according to the second aspect of the present invention, a learning disabled person or a blind person can quickly grasp the document structure as an information system through symbols and Braille printed on the document structure template sheet. In addition, detailed information associated with the symbols and braille can be efficiently reproduced through the barcode reading / reproducing apparatus.

  In the document information reproduction system of the present invention, the detailed information may be reproduced as sound. By reproducing the detailed information as a voice, the contents of the detailed information can be known even for a blind person, a learning handicapped person who is difficult to recognize characters, and an elderly person.

  According to the present invention, a learning handicapped person or a blind person can grasp a relatively large amount of information described on a paper systematically and easily in a short time, and the necessary information can be obtained from the barcode. A document structure template sheet that can be efficiently reproduced through the reproduction function of the reading / reproducing apparatus can be provided.

  Hereinafter, an example in which the document structure template sheet according to the present invention is applied to an examination question sheet in an entrance examination or the like will be described. In the following description, “document structure” means the structure of an examination question that has the examination subject name, question number, question sentence paragraph number, answer number, choice number / symbol, etc. as components. To do.

  FIG. 1A is a diagram showing a part of the document structure template sheet of the present invention, and FIG. 1B is an enlarged view of one area a of the document structure template sheet 1. The document structure template sheet 1 of the present invention includes a template sheet P having a plurality of areas a which are two-dimensionally partitioned, a braille 2 printed on the surface of the template sheet P, and an area on which the braille 2 is printed. a two-dimensional minimal barcode 3 recorded in a. For convenience of explanation, the outline of the two-dimensional minimal barcode 3 is shown by a dotted line in FIG. 1B, but it is actually invisible.

  The template paper P may be any paper that can print the braille 2 or the two-dimensional minimum barcode 3. In the present embodiment, as shown in FIG. 1A, a plurality of regions a (hereinafter referred to as “cells”) are partitioned on the surface of the template paper P in the X direction and the Y direction orthogonal to the X direction. Yes. These cells a are partitioned so that their sizes are equal. Specifically, the size of one cell is about 1 cm in length and about 5 mm in width. In the present embodiment, the template paper P is divided into 40 columns in the X direction and 19 rows in the Y direction. For convenience of explanation, in FIG. 1 (a) and FIG. 1 (b), the squares are indicated by solid lines, but are not actually printed on the template paper.

  On the surface of the template paper P, braille 2 representing one of the elements constituting the document structure is printed. Each braille 2 is printed so that it fits in one cell a defined on the surface of the template paper P.

  An invisible two-dimensional minimal barcode 3 is recorded on the cell a of the template paper P on which the braille 2 is printed. The two-dimensional minimal barcode 3 has a size of about 0.5 mm square. Therefore, a plurality of two-dimensional minimum barcodes 3 including the same information can be printed on one area a of the template paper P. Therefore, even when some two-dimensional minimal barcodes 3 are destroyed by printing the braille 2 on the two-dimensional minimal barcode 3, most of the two-dimensional minimal barcodes 3 can be read. Therefore, high reading reliability can be obtained.

  The two-dimensional minimal barcode 3 includes information regarding the position on the template paper P of the cell a in which the two-dimensional minimal barcode 3 is recorded. The information on the position on the template paper P includes information such as what page, what line, what line from the beginning of the template paper P, or what number in the line the template a is, for example, 10 It is coded in hexadecimal or hexadecimal.

  Next, the barcode reading / reproducing apparatus 10 used with the document structure template sheet 1 of the present invention will be described.

  The barcode reading / reproducing apparatus 10 includes a barcode reading unit 11, a storage unit 12, and a reproducing unit 13, as illustrated in the schematic configuration diagram of FIG. Any barcode reader 11 can be used as long as it can read the two-dimensional minimal barcode 3, but in order to ensure high reading reliability, the readable range is preferably narrow. .

  As the storage unit 12, for example, a non-volatile memory or the like can be used. The storage unit 12 associates the positional information on the template paper P converted into the decimal number or the hexadecimal number included in the two-dimensional minimal barcode 3 and the detailed information corresponding to the braille 2 printed at the position. Is remembered. When reproducing the detailed information by sound, for example, as shown in FIG. 2B, the file name of the sound file in which the detailed information is recorded may be stored in association with the position information on the template paper P. .

  Then, based on the position information included in the two-dimensional minimal barcode 3 read by the barcode reading unit 11, the reproducing unit 13 retrieves detailed information corresponding to the position information from the storage unit 12 and reproduces it. When the detailed information is reproduced by voice, the voice file name corresponding to the position information may be searched and the voice file corresponding to the voice file name may be played. In this case, the audio file may be stored in the storage unit 12.

  Next, a method for creating the document structure template sheet 1 from a test question created with normal characters will be described with reference to the drawings.

  FIG. 3 and FIG. 4 are diagrams showing a part (for two pages) of a test question created with normal characters. On the first page of the test question shown in FIG. 3, the name of the test subject, the question number, and the question sentence are described. The question sentence is composed of four paragraphs. The first paragraph is underline a, the second paragraph is underline b and underline c, the third paragraph is underline d and underline e, and the fourth paragraph is underline. There is a part where f and underline g are drawn. Then, on the second page of the test question shown in FIG. 4, a sub-question number, a question sentence, an answer number, and options are described.

  First, the creator of the document structure template sheet first expresses the document structure of the first page of the test question in Braille 2 on the document structure template sheet 1, so that the test subject name, question number, The number indicating the paragraph number and the underline in the paragraph is extracted from the first page of the test question. Then, the extracted components are associated with the cells on the template sheet. Specifically, from the first page of the exam question shown in FIG. 3, the test subject name “modern society A”, the question number “first question”, the paragraph numbers “1 to 4”, and the underline in the paragraph are shown. The symbols “a to g” are extracted. Then, these extracted components are associated with the cells a on the template paper P based on a predetermined rule. For example, one paragraph of a problem sentence is expressed by one line on the template paper P, one sentence included in one paragraph is expressed by “-” on the template paper P, and a symbol indicating an underline in the paragraph is a template. When the document structure of the first page of the test question is expressed on the document structure template paper 1 based on the rule of expressing with lower case letters on the paper P, it is expressed as the first to fifth lines from the top of FIG. Is done.

  Similarly to the case of the first page, in order to represent the document structure of the second page of the test question on the document structure template sheet 1 by Braille 2, from the second page of the test question shown in FIG. Sub-question number “question 1”, which is a component of the document structure, choices “a-e” in question sentence, answer number “1”, and answer choices “1-6” (circled numbers 1-6 in FIG. 4) Is extracted. Then, these extracted components are associated with the cells a on the template paper P based on a predetermined rule. For example, the document structure of the second page of the test question is represented on the document structure template sheet based on the rule that one sub-question is represented by one line on the template sheet P and two lines when the question sentence is long. Is expressed as the seventh to eighth lines from the top of FIG. In this way, the document structure template sheet of the present invention can express the document structure for two pages of test questions written in ordinary characters with only 8 lines, so the test question document structure can be easily formed in a short time. Can grasp. In addition, it is necessary to inform the test taker about the method of decoding the document structure created according to the above rules in advance.

  Next, the creator of the document structure template sheet 1 codes the position of the cell a on the template sheet P with which the structural elements of the document structure are associated. For example, FIG. 6 shows the page number (page) of the document structure template sheet, the line number (line) in the template sheet, the number of information in the line (item), and the position (position) from the beginning of the line in the line. The number of characters (length) of the information is represented by numbers, and a part of a table in which these numbers are converted into decimal and hexadecimal codes according to a predetermined rule is shown.

  Then, the creator of the document structure template paper 1 includes a decimal or hexadecimal code indicating the position of the cell a on the template paper P in the two-dimensional minimal bar code 3 and prints it on the cell a. At this time, as described above, since the two-dimensional minimal barcode 3 is very small, a large number of the same two-dimensional minimal barcode 3 can be printed on one cell a. Furthermore, the creator of the document structure template sheet 1 prints Braille 2 representing the component of the document structure associated with the cell a on the cell a. That is, the document structure template sheet 1 as shown in FIG. 1 can be created by printing the braille 2 from the two-dimensional minimal barcode 3 printed on the grid a.

  It should be noted that the creator of the document structure template sheet 1 reads the barcode as described above so that the blind person can reproduce the necessary information from the document structure template sheet 1 through the barcode reading / reproducing apparatus 10. The storage unit 12 of the playback apparatus 10 associates a decimal or hexadecimal code representing the position of the cell a on the template paper P with detailed information corresponding to the braille 2 printed on the cell a. It is necessary to memorize it. Here, the detailed information means detailed information on the components of the document structure, such as the content of one paragraph of the question sentence of the test question and the content of one option.

  In the document structure template sheet 1 of the present invention described above, since the plurality of cells a specified by the two-dimensional coordinate position are partitioned on the surface of the sheet, the position of each cell a on the template sheet P is set to the vertical position (row ), Horizontal position (row), and the like. For this reason, the braille 2 printed on the predetermined grid a of the template paper P can be uniquely associated with the position on the template paper P of the grid a on which the braille 2 is printed. The two-dimensional minimal barcode 3 printed on the grid a on which the Braille 2 is printed includes the position information of the grid a on which the Braille 2 is printed. Therefore, the Braille 2 and the two-dimensional minimal The barcode 3 is uniquely associated with the position information of the cell a. Therefore, a person who prints the two-dimensional minimal barcode 3 on the template paper P knows the position of the grid a on which the braille 2 is printed on the template paper P, and then encodes the position of the grid a to store the two. It may be included in the dimension minimum barcode 3 and printed on the cell a. In addition, since the two-dimensional minimal barcode 3 includes position information, the barcode reading / reproducing apparatus 10 may store detailed information in association with the position information, and the position information is uniquely specified. Therefore, the association work with the detailed information is also easy. Furthermore, even if the position for printing Braille is changed due to, for example, correction of the document structure, the changed position can be easily specified, and the position information stored in the barcode reading / reproducing apparatus 10 can be changed. The position information can be easily corrected later.

  Next, a method for using the document structure template sheet 1 of the present invention will be described. First, the blind person grasps the structure of the whole test question by tactile reading a plurality of Braille characters 2 printed on the surface of the template paper P. Then, the barcode reading unit 11 of the barcode reading / reproducing apparatus 10 is placed over a portion of the whole test question where a detailed information is desired, for example, a Braille portion indicating one sentence in the question sentence. Then, the barcode reading unit 11 recognizes the two-dimensional minimum barcode 3 recorded on the cell a on which the braille 2 is printed, and reads the position information on the template paper P included in the two-dimensional minimum barcode 3. In the storage unit 12 of the barcode reading / reproducing apparatus, position information on the template paper P and audio data of detailed information corresponding to the braille 2 recorded at the position are stored in advance in association with each other. Thereby, the audio data of the detailed information associated with the position information read from the two-dimensional minimum barcode 3 is reproduced by the reproduction unit 13 of the barcode reading / reproducing apparatus 10.

  Specifically, the blind person who has read the document structure template sheet 1 shown in FIG. 1 (a) reads the first question of the test question in the first row from the top (the top row is the 0th row). The structure of the first paragraph of the question sentence is shown, and the Braille 2a printed from the beginning of the first line to the seventh square a1 (the first line is assumed to be the zeroth square) is the first paragraph in the first paragraph. Can understand what is meant by a sentence. When it is desired to know the detailed contents of the first sentence in the first paragraph, the blind person holds the barcode reading unit 11 over the cell a1 on which the braille 2a is printed. As shown in FIG. 6, the cell a1 can be specified as the seventh cell from the first page, the first line, and the beginning of the template paper. When the position on the template paper is coded into a decimal number according to a predetermined rule, "530" The position information “530” is included in the two-dimensional minimal barcode 3 recorded in the cell a1. When the barcode reading unit 11 reads the position information “530” from the two-dimensional minimal barcode 3, the reproduction unit 13 of the barcode reading / reproducing apparatus 10 generates an audio file of detailed information associated with the position information “530”. A search is made from the storage unit 12, and the audio file is reproduced. As a result, the blind person is corroding the hull of the first sentence of the first question of the first question, the first sentence of “Spaceship Earth,” and the ship's fuel is running out. I am trying to get into a situation I have never experienced. Can be heard by voice.

  In the present invention, as the barcode reading / reproducing apparatus 10, for example, an IC recorder having a barcode reader attached to the tip which is already commercially available can be used. Further, a bar code reader may be connected to a personal computer, and audio information associated with the position information read by the bar code reader may be reproduced by an audio reproducing device built in the personal computer. In these cases, the IC recorder or personal computer needs to store in advance the positional information on the template paper and the voice data of the detailed information corresponding to the braille recorded at that position in association with each other.

  As described above, the present invention can be used as a document information reproduction system including a document structure template sheet and a barcode reading / reproducing apparatus. Blind persons can systematically understand the entire structure of the test questions in a short time by using the document information reproduction system, and only the detailed information about the necessary parts from the test questions is displayed on the barcode. It is possible to efficiently reproduce through the reproducing function of the reading / reproducing apparatus 10. When performing a test using the document information reproducing system of the present invention, it is desirable to provide an opportunity for the examinee to practice in advance how to use the document structure template sheet 1 and the barcode reading / reproducing apparatus 10.

  In the embodiment of the present invention described above, Braille 2 is printed on the surface of the document structure template sheet 1, but the question number, the symbol of options, etc., which are constituent elements of the document structure, are not the Braille 2. It may be printed with letters or symbols. In this case, since the structure of the test question can be grasped without reading all the long sentences of the test question, a learning handicapped person having a disability in character recognition can also take the test. Also, both braille and normal characters or symbols may be printed on the document structure template sheet. In this case, both the blind and learning disabled can use one document structure template sheet, and the document structure template sheet becomes general-purpose.

  In the above embodiment, the example in which the detailed information is reproduced as sound has been described. However, the reproduction of the detailed information is not limited to reproduction by sound. For example, the detailed information may be displayed with normal characters on a display such as a personal computer. In this case, a healthy person can read only necessary portions as characters on a display such as a personal computer using a document structure template sheet on which normal characters or symbols are printed. In addition, the characters may be displayed on a display such as a personal computer and may be played back by voice.

  Further, in the above embodiment, a plurality of the same two-dimensional minimal barcodes associated with the braille are recorded in the grid in which the braille is printed. Is not limited to the same grid as the one printed. For example, a document structure template sheet is created based on a predetermined rule that a two-dimensional minimum barcode is recorded in the vicinity of the upper, lower, left, or right side of a square printed with Braille, i.e., near the square printed with Braille. May be. In this case, the blind person may adjust the barcode reading unit to a predetermined vicinity of the printing position of the braille, and let the barcode reading unit read the two-dimensional minimal barcode recorded in the vicinity while touching the braille. Can do.

  As mentioned above, the example in which the document structure template sheet of the present invention is applied to the examination question sheet in the entrance examination etc. has been described. However, the document structure template sheet of the present invention is not limited to the entrance examination etc. It can also be applied to other books. For example, on one page of the document structure template sheet of the present invention, section numbers, section headings and paragraph numbers of paragraphs constituting each section are printed in Braille or normal characters on one page of the book. The two-dimensional minimum barcode associated with the Braille or normal character is printed in the area where the Braille or normal character is printed or in the vicinity thereof. Then, the barcode reading / reproducing apparatus stores detailed information associated with the two-dimensional minimal barcode as voice information. As a result, blind persons, persons with learning disabilities who have difficulty in recognizing characters, and the elderly can touch the area where the paragraph numbers are printed on the document structure template sheet by touching the barcode reading / playback device. The content of the paragraph corresponding to the number can be reproduced as audio information by the barcode reading / reproducing apparatus.
