Description

  The present invention relates to an idea extraction support system and method, and in particular, uses a camera, a wireless input device, and special paper, which are suitable for use in creating an idea by a plurality of people using the KJ method or the like. The present invention relates to an idea extraction support system and method.

  As a technique used when an individual or a plurality of persons create new knowledge or aggregate ideas possessed by each person, a method called a KJ method is known. In the KJ method, ideas and opinions extracted by brainstorming and the like are written to a card one by one, and the grouping is repeated for collecting and classifying the contents that are close to each other, thereby organizing the relationships between the groups. It is a method. And in this work, discovery of the essence of ideas and creation of new ideas are performed.

  When the KJ method is performed, a sticky note is generally used as the above-described card, and a method of sticking the sticky note on a dummy paper or the like is often used. However, such a method has a problem that it takes time and effort to record information such as an idea written on a tag by digitization or the like. For digitization, it is possible to take a method of storing it as an image with a digital camera or the like. However, considering that it will be used later, a task of writing a keyword as an idea written on a tag occurs.

  On the other hand, there is a case where the KJ method is performed by using a KJ method tool or the like without using a sticky note and projecting the state onto a projector. In this case, since the keyword is digitized in an information device such as a personal computer, it is easy to write the keyword or hold the grouped result.

  However, the above-described method using the KJ method tool takes time and effort to input keywords from a keyboard or the like, interrupting the thinking of the KJ method work, and comparing each card by hand. It is difficult to achieve the original purpose of the KJ Law, which is to create new ideas and inspiration during grouping work, and joint work and consensus building by multiple people Is difficult.

As a conventional technique related to an idea extraction support method as a solution to the above-described problem, for example, a technique described in Patent Document 1 is known. This prior art uses a sticky note with a code having an area for entering characters, and uses an image identification means that reads the code identifier, the image of the entry area and the position of the code from the sticky note, in the idea extraction process. Information can be digitized.

Information acquired by the camera 301 (for example, handwriting information such as a character trajectory, stroke order, and speed) is recognized as an image by the image processor 304. This information and the pen pressure information acquired from the pen pressure sensor 302 are temporarily stored as pen information in the memory 306 and then sent to the information acquisition terminal 103 via the communication unit 307.

  FIG. 4 is a diagram illustrating a configuration example of the card 102 using a special sheet with a wireless tag. The card 102 is a device to which a wireless tag 402 is attached and a special pattern for identifying information such as which position of which card is filled with characters and the like is printed. As shown in FIG. 4, the card 102 includes a dot pattern 401 and wireless tags 402 in which dots printed at equal intervals are arranged on the surface of the card. The dot pattern 401 is a mechanism for creating a pattern by combining the arrangement of dots drawn in a grid pattern. In brainstorming and KJ method, by making the combination of the dot pattern 401 printed on the card as the paper to be used unique, it is possible to identify each card 102 and the entry position of characters etc. in the card It becomes. The dot pattern 401 is photographed by the camera 301 of the input device 101 together with the entered character information and recognized as an image by the image processor 304.

  The mount 107 is basically the same as the card 102 except for the size. As with the card 102, a plurality of cards 102 are prepared for writing an idea on one mount made of special paper with a wireless tag, and information on each card is stored in the paper identification DB 206 in advance. Are registered as correspondence information between the dot pattern and the card.

  FIG. 5 is a diagram illustrating a configuration example of the sheet identification DB 206. The paper identification DB 206 includes columns of a paper identifier 501, dot pattern information 502, and tag identifier 503. The paper identifier 501 is a unique identifier assigned to each card 102. The dot pattern information 502 holds a special information type for identifying each card or an image of a dot pattern printed on the card. The tag identifier 503 is a unique identifier uniquely assigned to the wireless tag 402 attached to each card 102. Note that there is only one combination of the paper identifier 501, dot pattern information 502, and tag identifier 503 for any paper identifier 501, dot pattern information 502, and tag identifier 503. Therefore, it is possible to specify the card 102 from either of the dot pattern information 502 and the tag identifier 503.

  The pen information controlled by the pen information image acquisition processing unit 201 of the information acquisition terminal 103 and sent from the communication unit 307 of the input device 101 to the information acquisition terminal 103 is sent to the information management server 104 via the communication unit 218. The image data processing unit 203 recognizes characters. At the same time, the paper information is also compared with the dot pattern of the paper identification DB 206 by the image data processing unit 203 to specify the paper and the position of the pen information described on the paper. These pieces of information are stored in the character information DB 205 as information in which the identifier of the card 102, the position of the pen information written on the card 102, the written contents, and the image of the pen information are associated with each other.

  When brainstorming or KJ method is performed using the system, each of a plurality of participants writes information on one or a plurality of cards 102 held by each participant using the input device 101. Information on these cards is stored in the character information DB 205 of the information management server 104 as described above. The cards 102 on which information is recorded by each of a plurality of participants are placed on the mount 107, and cards on which information that is considered to be related are recorded are grouped together. At this time, the relationship between the grouped information is also written on the mount 107, but the relationship may be expressed by connecting with a line. In this case, the image data processing unit 203 cannot recognize the line information as character information, and thus it is difficult to record the information. It can be obtained by looking at an image of information, or it can be obtained as character information by writing a character explaining the relevance in the vicinity of a line image on the mount.

  FIG. 6 is a diagram illustrating a configuration example of the character information DB 205. The character information DB 205 includes columns of a paper identifier 601, a description information position 602, a description content 603, and a pen information image 604. The paper identifier 601 is a unique identifier assigned to each card 102 and is the same as the paper identifier 501 described with reference to FIG. The description information position 602 holds information indicating in which part (position) on the card 102 pen information is described. This information is the distance in the horizontal and vertical directions with the lower left corner of the card 102 as the base point. The description content 603 holds the pen information recognized by the image data processing unit 203, and the pen information image 604 holds the image recognized by the image processor 304 before being recognized by the image data processing unit 203. .

  FIG. 8 is a diagram illustrating a method for calculating the description information position 602 in the image data processing unit 203. The image data processing unit 203 calculates the position of the leftmost pen information of the leftmost character described on the card 102. That is, the image data processing unit 203 uses the lower left corner of the card 102 as a base point, measures the distances in the horizontal axis direction 801 and the vertical axis direction 802 from the base point, and sets these distances as a description information position 602 as a pair. The distance can be measured by using a dot pattern printed on the card 102. Note that the card 102 is handled assuming that the attachment position of the wireless tag 402 of the card to which the wireless tag 402 is attached is the upper left corner.

  FIG. 9 is a diagram for explaining an example in which a plurality of cards 102 are placed on a mount 107 and characters are written on the mount, and acquisition of character position information on the mount.

  As shown in FIG. 9, in order to perform brainstorming and the KJ method, a plurality of cards on which information is written are grouped on the mount 107, and each group is surrounded by an ellipse as shown by a dotted line. . Then, the relationship between a group in one ellipse and a group in another ellipse is shown connected by a dotted line with an arrow, and a character string representing the relationship is written on the mount 107 near the dotted line.

  The writing of the information described on the mount 107 using the special paper with the wireless tag as described above to the description information position 602 of the character information DB 205 is performed by a process different from the card 102. That is, the image data processing unit 203 of the information management server 104 measures the distance between recognized characters, determines that a character described within a certain distance is a character string, and determines a character having a certain distance from another character. After performing processing for determining a character string, the character information DB 205 holds the record as a record different from the card 102 character information.

  In FIG. 9, the image data processing unit 203 measures the distances in the horizontal axis direction 906 and the vertical axis direction 907 from the base point for each of the characters 901 to 905 written on the mount 107, and then between the characters. The characters 901, 902, and 903 within a certain distance are determined as one character string 908, and the characters 904 and 905 are determined as one character string 909. Note that the character string 908 and the character string 909 are determined to be separate character strings because there is a certain distance or more.

  The wireless tag 402 is a wireless tag with a built-in battery called active RFID, and emits a signal by itself. For example, the wireless tag 402 transmits information of the own tag every several seconds. The tag information reading unit 210 receives information from the wireless tag 402 on the card 102, and if the card 102 has not moved for a certain time after moving on the mount 107, the position of the card 102 on the mount 107 is determined. Is calculated. The position information of the card 102 on the mount 107 calculated by the tag information reading unit 210 is written in the position information DB 207. For the movement of the card 102 on the mount 107 and the detection of the position of the card 102 on the mount, the method described in Patent Document 1 described above can be used.

  FIG. 7 is a diagram illustrating a configuration example of the position information DB 207. The position information DB 207 includes columns of time 701, tag identifier 702, and tag position information 703. At the time 701, the time when the signal is emitted from the wireless tag 402 is held, and the tag position information 703 indicates the distance in the horizontal direction and the vertical direction of the wireless tag 402 when the lower left of the mount 107 is used as a base point. Is retained. The tag identifier 702 is a unique identifier assigned to each wireless tag 402.

  FIG. 10 is a diagram illustrating a method for calculating the paper position information 602 in the tag recognition processing unit 204. The tag recognition processing unit 204 calculates the position of the wireless tag 402 of the card 102 placed on the mount 107. The calculation of this position is performed by measuring the distance in the horizontal axis direction 1001 and the vertical axis direction 1002 from the base point. At this time, the cards 102 may overlap. Further, by unifying the sizes of the cards 102 other than the mount 107 and measuring the distance between the wireless tags 402, it is possible to recognize how the keywords described in the cards 102 are grouped.

  Information stored in the character information DB 205, the paper identification DB 206, and the position information DB 207 by the processing described above can be viewed and processed from the user terminal 105 through the display unit 209. The display unit 209 is based on a thought process browsing screen showing the transition of brainstorming or KJ method work, a reproduction information providing screen for reproducing the situation before the interruption when the work is resumed, and the computerized information. A KJ method work screen for continuing the work is displayed on the user terminal 105 in accordance with a request from the user terminal 105. These display screens are created by the data processing unit 208.

  FIG. 11 is a diagram illustrating an example of a thought process browsing screen displayed on the user terminal 105. When the user terminal 105 requests a thought process browsing screen to the information management server 104, the display unit 209 in the server 104 displays a thought at a certain time as shown in FIG. 11A created by the data processing unit 208. The process browsing screen 1102 is transmitted to the user terminal 105 and displayed. This display screen is a screen for displaying a state where a plurality of cards 102 are placed on the mount 107 as a transition state at that time, and a time display 1101 that can change the time is also displayed.

  Then, by moving the time using the cursor of the time display 1101, a browsing screen 1103 showing the transition state of each card at the time of the moved position as shown in FIG. It can be grasped. By setting the time display 1101, the time can be automatically advanced or manually advanced. The thinking process browsing screen can be created by combining the position information DB 207 and the character information DB 205, and the description content 603 is displayed on the card 102, or the transition of the tag position information 703 at each time 701 is displayed using animation. Can also be easily realized.

  FIG. 12 is a diagram illustrating an example of a reproduction information provision screen displayed on the user terminal 105. This reproduction information provision screen is also a screen that is displayed when a request for a reproduction information provision screen is made from the user terminal 105 to the information management server 104, as in the case of FIG. It is a screen that reproduces the situation used in the storming and KJ table. This screen is composed of a screen 1203 showing a state where a plurality of cards 102 are placed on the mount 107 and a reproduction support screen 1202.

  On this reproduction information providing screen, when the mouse is placed on each card 102 on which characters such as keywords are written, a label position 1201 is shown. At the same time, a tag identifier 1203, an arrangement position 1204, A current position 1205 is displayed. Based on the information obtained from the wireless tag 402 and the tag recognition processing unit 204, the current position 1205 displays the tag position information of the card 102 that the user is holding (mouse is on). The The user can drag and move the card so that the current position 1205 matches the arrangement position 1204, and can easily reproduce the same situation as before the interruption.

  FIG. 13 is a diagram illustrating an example of a work screen when work by the KJ method displayed on the user terminal 105 is performed on the screen of the user terminal 105. This work screen is composed of a screen 1302 showing a state in which a plurality of cards 102 are placed on the mount 107 and a toolbar 1301. In this work screen, the situation used in the brainstorming or KJ method is reproduced on the screen, and the work performed on the desk can be performed through the user terminal 105 by using the function of the toolbar 1301. Further, since this work information is also stored electronically, it is possible to reproduce information reflecting work performed on the user terminal on the desk by updating the position information DB 207.

  According to the present embodiment, in the process of extracting ideas to be digitized when brainstorming or KJ method is performed on a desk, the user can concentrate on the work such as KJ method without being aware of the work of extracting the idea, and the idea extraction.
