Description

  The present invention relates to a technique capable of extracting and processing specific information from information entered with an electronic pen.

  Usually, when attending a lecture or attending a meeting, a user often takes notes on a university note or a loose leaf composed of a plurality of ruled lines. Unlike electronic data, information written on such a paper medium cannot be easily deleted or sorted. Therefore, if information described on the paper medium can be managed as electronic data on a server or personal computer (hereinafter referred to as “PC”), it is convenient because deletion and sorting can be easily performed. .

  In this way, when information written on paper media is managed as electronic data on a server or PC, a user who visually recognizes a university note or loose leaf whose contents have been memo punched or entered as image data with a scanner. It is necessary to drool.

  However, inputting electronic data based on a handwritten university note or loose leaf takes time and effort, and causes a problem that the burden on the user is heavy. Furthermore, the punch input may cause human error due to manual work.

  In addition, information written on paper media that is not divided into multiple items, such as university notes and loose leaves, is not clearly linked to each other, so the corresponding electronic data is divided based on the user's intention. There is also a problem that it is difficult to subdivide and manage on a server or a PC.

  Preferred embodiments of the present invention will be described below with reference to the drawings. First, an outline of an electronic pen used as an input device in the system of the present embodiment will be described.

[Electronic pen]
FIG. 1 is a diagram schematically showing how the electronic pen is used, and FIG. 2 is a block diagram showing the structure of the electronic pen. As shown in FIG. 1, the electronic pen 10 is used in combination with a dedicated paper 20 on which a dot pattern is printed. The electronic pen 10 includes a pen tip portion 17 similar to a normal ink pen, and a user writes characters on the dedicated paper 20 in the same manner as a normal ink pen.

  As shown in FIG. 2, the electronic pen 10 includes a processor 11, a memory 12, a data communication unit 13, a battery 14, an LED 15, a camera 16, and a pressure sensor 18 therein. The electronic pen 10 includes an ink cartridge (not shown) as a component similar to a normal ink pen.

  The electronic pen 10 does not convert the locus of the ink drawn on the dedicated paper 20 by the pen tip unit 17, but converts the locus coordinates of the movement of the electronic pen 10 on the dedicated paper 20 into data. While the LED 15 illuminates the vicinity of the pen tip 17 on the dedicated paper 20, the camera 16 reads the dot pattern printed on the dedicated paper 20 and converts it into data. That is, the electronic pen 10 can acquire a stroke generated when the user moves the electronic pen 10 on the dedicated paper 20 as image data or vector data.

  The pressure sensor 18 detects the pressure applied to the pen tip portion 17 when the user writes characters on the dedicated paper with the electronic pen 10, that is, the writing pressure, and supplies the detected pressure to the processor 11. The processor 11 switches the LED 15 and the camera 16 on and off based on the writing pressure data given from the pressure sensor 18. That is, when the user writes characters or the like on the dedicated paper 20 with the electronic pen 10, writing pressure is applied to the pen tip portion 17. Therefore, when the writing pressure exceeding the predetermined value is detected, it is determined that the user has started the description, and the LED 15 and the camera 16 are operated.

  The camera 16 reads the dot pattern on the dedicated paper 20 and supplies the pattern data to the processor 11. The processor 11 calculates X and Y coordinates on the dedicated paper 20 from the supplied dot pattern.

  The processor 11 acquires writing pressure array data and X and Y coordinate data while the user's description is performed, and stores them in the memory 12 in association with a time stamp (time information). Therefore, data corresponding to the description content of the user is stored in the memory 12 in time series. The capacity of the memory 12 can be about 1 Mbyte, for example.

  All the acquired data is held in the memory 12 until a transmission instruction is given by the user. When the user issues a transmission instruction, the data communication unit 13 transmits the data in the memory 12 to the terminal device 25 within a predetermined distance from the electronic pen 10. Basically, once a transmission instruction is given, the electronic pen 10 transmits all the data stored in the memory 12 to the terminal device 25, so that the memory 12 is cleared. Therefore, when it is desired to transmit the same information to the terminal device 25 again after transmission, the user needs to write the description on the dedicated paper 20 again. In this case, the user only has to trace characters written on the dedicated paper 20 with an ink pen.

  The electronic pen 10 itself does not include a function button such as a transmission button, and a transmission instruction and other instructions are performed by a user checking the dedicated box provided at a predetermined position on the dedicated paper 20 with the electronic pen 10. Executed. A transmission instruction is associated with the position coordinates of the dedicated box in advance. When the processor 11 receives the position coordinates of the dedicated box, the processor 11 supplies data in the memory 12 to the data communication unit 13 and transmits the data to the terminal device 25. To do. The electronic pen 10 can indicate completion of data transmission by vibration of the electronic pen.

  The battery 14 is for supplying power to each element in the electronic pen 10, and the electronic pen 10 itself can be turned on / off by a cap (not shown) of the electronic pen, for example.

  As described above, the electronic pen 10 has a function of acquiring coordinate data and writing pressure data corresponding to characters and the like described on the dedicated paper 20 by the user and transmitting them to the nearby terminal device 25. Since the pen tip portion 17 is a normal ink pen, the content described on the dedicated paper 20 remains as an original original. That is, at the same time as describing the original paper, its contents can be digitized in the form of coordinate data in real time.

  According to the standard function of the electronic pen 10, data obtained by the electronic pen 10 is in principle in the form of coordinate data or vector data, and is not text data. However, as a standard function, the electronic pen 10 has a function of converting text into alphanumeric characters by describing it in a dedicated area provided on the dedicated paper 20.

  Also, the electronic pen 10 can hold property information (pen information and pen owner information) regarding the pen itself and its owner, and can be referred to from an application. As the pen information, a battery level, a pen ID, a pen manufacturer number, a pen software version, a subscription provider ID, and the like can be held. The pen owner information can hold nationality, language, time zone, email address, free memory capacity, name, address, fax / phone number, mobile phone number, and the like.

  In the data communication unit 13 in the above example, the electronic pen 10 is connected to the terminal device 25 by various methods such as Bluetooth (registered trademark) wireless transmission, wired transmission using a USB cable, and data transmission by contact with a terminal. It is conceivable to perform data transmission.

  Next, a method for acquiring X and Y coordinate data of contents described by the user with the electronic pen will be described. As described above, a predetermined dot pattern is printed on the dedicated paper 20. The camera 16 of the electronic pen 10 does not read the locus of ink described on the dedicated paper 20 by the user, but reads the dot pattern on the dedicated paper 20. Actually, as shown in FIG. 1, the illumination area by the LED 15 and the shooting area of the camera 16 (located in the illumination area) are deviated from the position where the pen tip portion 17 contacts the dedicated paper 20.

  The dot pattern is printed with a special ink containing carbon, and the camera 16 can recognize only the pattern with the special ink. Even if ruled lines or frames are printed on dedicated paper with inks other than dedicated ink (not including carbon), the electronic pen does not recognize them. Therefore, when creating forms such as various application forms using dedicated paper, input frames, ruled lines, cautions, etc. are printed with ink other than dedicated ink.

  In the dot pattern, as illustrated in FIG. 3, the position of each dot is associated with data. In the example of FIG. 3, the 2-bit information of 0 to 3 is displayed by shifting the dot position vertically and horizontally from the reference position (intersection of vertical and horizontal lines) of the grid. The position coordinates on the dedicated paper are determined by the combination of information expressed in this way. As illustrated in FIG. 4A, 36 dots are arranged in a grid within a range of 2 mm in length and width, and the data array (FIG. 4B) indicated by these dots is displayed on the dedicated paper. Are associated with the position coordinates. Therefore, when the camera 16 of the electronic pen 10 captures a dot pattern as shown in FIG. 4A, the processor 11 changes the data array shown in FIG. 4B based on the dot pattern data input from the camera 16. The position coordinates on the dedicated paper (that is, where the dot pattern is located on the dedicated paper) corresponding to the acquired position are calculated in real time. The minimum unit for recognizing the dot pattern is 2 mm × 2 mm, and the camera 16 takes about 100 shots per second.

  Next, the dedicated paper will be described. An example of the structure of the dedicated paper is shown in FIG. As shown in the figure, the dedicated paper 20 has a dot pattern 32 printed on a mount 30 and a design 34 such as a ruled line printed thereon. The mount 30 is usually paper, and the dot pattern 32 is printed with dedicated ink containing carbon as described above. Further, the design 34 is printed with normal ink or the like. The dot pattern and the design may be printed at the same time, or one of them may be printed first.

  An example of the design 34 is shown in FIG. FIG. 6 shows an example of a certain application form 36 in which a plurality of entry fields 38 and a transmission box 39 are printed. Although it is not clearly shown in FIG. 6 and will be described in detail later, a dot pattern is actually printed on the entire surface of the application form 36, and an entry box 38 and a transmission box 39 are formed on the entire surface using ordinary ink. It is printed. The user can enter the necessary items in each entry field 38 of the application form 36 using the electronic pen 10 in the same manner as a conventional application form without being aware of the dot pattern.

  The area on the dedicated paper 20 can be roughly divided into two types. One is an entry area, in which the content described by the electronic pen 10 is handled as information as it is. In the example of FIG. 6, a plurality of entry fields 38 correspond to this. The other is a functional element, and when the corresponding area is checked with the electronic pen 10, actions, instructions, etc. defined in advance for the area are executed. The transmission box 39 in the example of FIG. 6 corresponds to this.

  The transmission box 39 is used when giving an instruction to transmit data stored in the electronic pen 10 to the nearby terminal device 25 as described above. When the user checks the transmission box 39 with the electronic pen 10, the electronic pen 10 reads the dot pattern in the transmission box. The pattern is associated with a transmission instruction, and the processor 11 in the electronic pen 10 issues a command to transmit data stored in the memory 12 to the data communication unit 13.

  The assignment of dot patterns is usually performed for each application (paper type). In other words, the dot patterns in a certain application form do not overlap in one sheet, but the same dot pattern is printed on the same application form. Therefore, when the user inputs necessary items with the electronic pen 10, it can be specified from the coordinate data on the application form which item of the application form the input item is for.

  As described above, by printing a predetermined design on the dedicated paper on which the dot pattern is printed, various application forms using the dedicated paper can be created. If the user uses the electronic pen 10 and fills in necessary items in a normal manner, the electronic data is automatically acquired.

  In the above example, the dot pattern is printed on the dedicated paper with carbon-containing ink. However, the dot pattern can be printed on ordinary paper using a printer and carbon-containing ink. Furthermore, the design on the dedicated paper can also be formed by a printer instead of printing. When dot patterns are formed on paper by a printer, different dot patterns can be formed on each sheet. Therefore, it is possible to identify and distinguish each of these sheets by the difference in the formed dot patterns.

  In the present specification, the term “printing” has a concept including not only normal printing but also printing by a printer.

  Next, transmission processing of data acquired by the electronic pen will be described with reference to FIG. The data acquired by the electronic pen 10 is mainly data of items input by the user, but usually does not include information on where the service server that is the transmission destination of the data is. Instead, information specifying the application or service related to the dedicated paper is included in the dot pattern on the dedicated paper, and the information is acquired from the dedicated paper during the user's input operation. Therefore, the terminal device 25 that has received the entry data from the electronic pen 10 first makes an inquiry to the inquiry server 26 to which service server 27 the data input to the dedicated paper should be transmitted. The inquiry server 26 has information on a corresponding service server for each dedicated paper, and in response to an inquiry from the terminal device 25, information (such as a URL) of the service server 27 that performs a service related to the dedicated paper. Reply to the terminal device 25. Then, the terminal device 25 transmits the entry data acquired from the electronic pen to the service server 27.

  In the above example, the terminal device 25, the inquiry server 26, and the service server 27 are separately configured. However, some or all of them may be configured as one device. In the present embodiment, it is assumed that a server described later also serves as the inquiry server 26 and the service server 27.

[Information processing system]
Next, the entry information processing system of this embodiment will be described. FIG. 7 shows a schematic configuration of the entry information processing system 100. The entry information processing system 100 shown in FIG. 7 is not divided into a plurality of items, and an electronic pen 10 is used by a user on an electronic pen form (hereinafter referred to as “notebook”) configured by a plurality of ruled lines. The entry information entered using is subdivided according to the user's intention, and predetermined processing is performed.

  As shown in FIG. 7, the entry information processing system 100 is configured by connecting a terminal device 25 and a server 5 through a network 2. Here, one suitable example of the network 2 is the Internet. The terminal device 25 is a terminal that can exchange data via the network 2 such as a PC or a mobile phone used by a user. The server 5 is connected to an entry information database (hereinafter referred to as “DB”) 7.

  First, the outline of the method for subdividing entry information by this system will be described. The notebook 3 is created as the above-mentioned dedicated paper, and is composed of a plurality of ruled lines as shown in FIG. Here, note 3 is set with a row confirmation mark 40 necessary for the user to intentionally indicate a specific area and a column confirmation mark 60 necessary for indicating a format arbitrarily set by the user. ing.

  The user enters predetermined contents into the note 3 using the electronic pen 10. At this time, although details will be described later, the user can arbitrarily set the format of the note 3 by entering a vertical line passing through the column confirmation mark. In addition, the user can specify and subdivide a predetermined area from the contents entered in the note 3 by entering a horizontal line, parentheses, or a rectangle passing through the line confirmation mark.

  The electronic pen 10 acquires stroke data corresponding to the entered contents, temporarily stores it in the memory 12 in the electronic pen 10, and then transmits the stroke data to the terminal device 25. The terminal device 25 receives the stroke data from the electronic pen 10 and transmits it to the server 5 through the network 2. The server 5 acquires the stroke data as entry information indicating the contents entered by the user on the note 3. Further, the server 5 extracts the row confirmation mark and the column confirmation mark included in the entry information, and grasps the format set and the specified area based on the position information of each mark. Here, the fact that a row confirmation mark and a column confirmation mark are included means that entry information passing through the coordinates where each confirmation mark is located on the dot pattern of the note 3 is included. That is, the row confirmation mark and the column confirmation mark included in the entry information are each confirmation mark when there is entry information passing through the coordinates where each confirmation mark is located. Then, the server 5 performs predetermined processing on the entry information according to the set format and the specified area.

  In this way, the server 5 can perform predetermined processing by subdividing the entry information entered by the user using the electronic pen 10 in accordance with the intention of the user.

  Note that a transmission box is not described in the note 3 shown in FIG. 8 for the sake of convenience, but it is assumed that a transmission box having the same function as the transmission box 39 shown in FIG.

[Note]
Next, note 3 will be described. In the system of the present embodiment, the notebook 3 as shown in FIG. 8 is created as the dedicated paper described above. That is, as illustrated in FIG. 5, a predetermined dot pattern 32 is printed on the mount 30, and a predetermined mark or ruled line is printed thereon. As described above, the dot pattern 32 is printed with ink containing carbon so that the electronic pen 10 can recognize it. On the other hand, since the design 34 such as a mark or a ruled line is printed with normal (not including carbon) ink, the electronic pen 10 does not recognize it.

  Here, the process performed when the user enters a line passing through the row confirmation mark or the column confirmation mark on the notebook 3 will be described in detail.

(I) Storage Processing The upper part of FIG. 9 shows an example in which a paragraph area is specified by a horizontal line passing through a line confirmation mark provided in the note 3. In the present embodiment, the server 5 acquires the stroke data received from the electronic pen 10 as image data. That is, since the entry information is image data, the server 5 does not perform processing such as character recognition based on the stroke data. Although details will be described later, coordinate data defining each mark provided on the note 3 is stored in advance in a coordinate table.

  It is assumed that the user enters predetermined lecture contents in the note 3 using the electronic pen 10 and further enters a horizontal line 51 passing through the line confirmation marks 40a and 40b as shown in the upper part of FIG. The electronic pen 10 generates data indicating which coordinate of the note 3 has been entered based on the dot pattern and stores the data in the internal memory 12. Accordingly, when the entry is made as shown in FIG. 9, the electronic pen 10 acquires the entry position coordinates on the notebook 3 and stores them in the memory 12. When the user enters a check mark in a transmission box provided on the notebook 3, the entry position coordinates stored in the memory 12 are transmitted from the electronic pen 10 to the terminal device 25. That is, the server 5 acquires, as entry information, information indicating that the lecture content and the horizontal line 51 passing through the line confirmation marks 40a and 40b are entered on the notebook 3 based on the entry position coordinates.

  The server 5 that has acquired such entry information recognizes that a horizontal line 51 passing through the line confirmation marks 40a and 40b has been entered in the note 3 with reference to a coordinate table described later. Then, the server 5 identifies the area from the beginning of the note 3 to the horizontal line 51 as the paragraph area 50 and assigns an area ID “A01” for identifying the area to the paragraph area 50. Then, the server 5 stores image data representing the contents described in the paragraph area 50 using the area ID “A01” as a key in the entry information DB 7 shown in FIG.

  In this way, when the user uses the electronic pen 10 to write a line passing through the two line confirmation marks on the notebook 3, the server 5 identifies the area separated by the line as a paragraph area. Then, a storage process for storing the contents described in the paragraph area in the entry information DB 7 using the area ID as a key is performed. It should be noted that when the horizontal line for specifying the paragraph area passes through two line confirmation marks, that is, both ends of the horizontal line are line confirmation marks, the user can use the electronic pen 10 as a condition for specifying the paragraph area. When writing using, it is possible to prevent malfunction when the line touches the line confirmation mark by mistake and to distinguish the horizontal line for identifying the paragraph area from the horizontal line being written. .

(Ii) Deletion Process The lower part of FIG. 9 shows an example in which a deletion area is specified by a diagonal line passing through a line confirmation mark provided in the note 3. A user enters a predetermined lecture content in the note 3 using the electronic pen 10, and as shown in the lower part of FIG. 9, a diagonal line 54a passing through the line confirmation marks 40c and 40f and a diagonal line passing through the line confirmation marks 40d and 40e. 54b is further entered. In this case, the server 5 that has acquired the entry information refers to a coordinate table (to be described later) and notes that the entry information includes a diagonal line 54a passing through the line confirmation marks 40c and 40f and a diagonal line 54b passing through the line confirmation marks 40d and 40e. Recognize that 3 was entered. Then, the server 5 identifies the area surrounded by the line confirmation marks 40c to 40f included in the oblique lines as the deletion area 53, and deletes the image data representing the contents described in the deletion area 53 from the acquired entry information. .

  As described above, when the user uses the electronic pen 10 to write two diagonal lines passing through the two line confirmation marks on the notebook 3, the server 5 deletes the area surrounded by the line confirmation marks from the deletion area. And delete processing for deleting the contents described in the deletion area from the acquired entry information.

  In the example of the deletion process described above, the user enters two oblique lines that pass through the four line confirmation marks in order to specify the deletion area. However, the present invention is not limited to this. The deletion area may be specified by one oblique line passing through two row confirmation marks. Further, the server 5 may perform gray-out processing when the deletion area is specified by one oblique line, and may perform deletion processing when the deletion area is specified by two oblique lines. Here, the grayout process is a process that does not delete the contents described in the deletion area from the acquired entry information but prevents the server or PC user from performing editing for management. . That is, the grayed-out entry information can be viewed but cannot be edited or edited.

(Iii) Extraction Processing The upper part of FIG. 10 shows an example in which the extraction area is specified by parentheses that pass through the line confirmation mark provided in the note 3. It is assumed that the user uses the electronic pen 10 to write a predetermined lecture content in the note 3 and further fills in parentheses 56 passing through the line confirmation marks 40i and 40k as shown in the upper part of FIG. In this case, the server 5 that has acquired the entry information refers to a coordinate table to be described later and recognizes that the parenthesis 56 that passes through the line confirmation marks 40i and 40k is entered in the note 3 in the entry information. Then, the server 5 specifies the area from the upper line confirmation mark 40i to the lower line confirmation mark 40k as the extraction area 57, and performs predetermined processing on the image data representing the contents described in the extraction area. . Here, it is assumed that the predetermined processing is preset and depends on the application.

  In the above example, the line for specifying the extraction area is shown in parentheses, but the present invention is not limited to this, and the extraction area is specified if two or more line confirmation marks pass vertically. Shall be able to.

  In this way, when the user uses the electronic pen 10 to enter a line passing vertically through two or more line confirmation marks on the notebook 3, the server 5 extracts the area indicated by the line confirmation mark as the extraction area. And a predetermined process is performed on the contents described in the extraction area.

  The lower part of FIG. 10 shows an example in which the extraction area is specified by a rectangle passing through the line confirmation mark provided in the note 3. It is assumed that the user enters predetermined lecture contents in the note 3 using the electronic pen 10 and further enters a rectangle 58 passing through the line confirmation marks 40m to 40p as shown in the lower part of FIG. In this case, the server 5 that has acquired the entry information refers to a coordinate table to be described later and recognizes that the rectangle 58 passing through the line confirmation marks 40m to 40p is entered in the note 3 in the entry information. Then, the server 5 specifies the area surrounded by the line confirmation marks 40m to 40p as the extraction area 59, and performs predetermined processing on the image data representing the contents described in the extraction area.

  In the above example, the line for specifying the extraction area is a rectangle, but the present invention is not limited to this, and three or more line confirmation marks can be passed so as to surround the specific area. It is assumed that the extraction area can be specified.

  In this way, when the user uses the electronic pen 10 to write a line passing through three or more line confirmation marks on the notebook 3 so as to surround a specific area, the server 5 can display the line confirmation marks. The indicated area is specified as an extraction area, and a predetermined process is performed on the contents described in the extraction area.

(Iv) Format Processing FIG. 11 shows an example in which the format is specified by the vertical line passing through the column confirmation mark provided in the note 3.

  Here, note 3 is set such that when a vertical line passing through the leftmost column confirmation marks 60a and 60b is entered, the left side of the vertical line is regarded as a date entry area. Note that it is difficult for the user to recognize characters entered in the date entry area with the electronic pen 10. Therefore, it is used together with the horizontal line for specifying the paragraph area described in (i) above, and the time of the first stroke entered in the date entry area after the paragraph area is specified by the horizontal line is acquired as the entry date. In addition, when a vertical line passing through the center column confirmation marks 60c and 60d is entered, it is set that the vertical line is regarded as a column line. To consider as a column line means that the image data included in the entry information is divided on the left and right, and the next on the left side is stored and processed as the right side.

  Note that the column information can be arbitrarily set other than the above example.

  In this way, in the note 3, when a vertical line passing through a predetermined column confirmation mark is entered, what information is entered in a column constituted by the vertical line is preset. Information set in each column based on the vertical line passing through such a column confirmation mark is referred to as column information.

  When the user wants to set the format in which the notebook 3 is divided into two columns and the date and time of entry is set in the left column and the lecture contents are written in the right column, the electronic pen 10 is used to set the format. As shown in FIG. 11, a vertical line 61 passing through the column confirmation marks 60a and 60b is entered. The user enters the entry date and time on the left side of the vertical line 61 and the lecture content on the right side. In this case, the server 5 that has acquired the entry information refers to a coordinate table described later and recognizes that the vertical line 61 passing through the column confirmation marks 60a and 60c is entered in the note 3 in the entry information. Then, based on the column information set in advance, the server 5 has the note 3 in which the area on the left side of the vertical line 61 is the date entry area, and the area on the right side of the vertical line 61 is entered in the date entry area. Set the format to be information written on the date. Therefore, when storing the entry information in the entry information DB 7, the server 5 stores the information entered on the right side of the vertical line 61 in association with the date entry area.

  In this way, when the user uses the electronic pen 10 to enter a vertical line that passes through the column confirmation mark on the notebook 3, the server 5 stores the column information that is set in advance in association with the column confirmation mark. Based on this, the format intended by the user is grasped, and processing according to the format is performed on the entry information.

(V) Category Processing FIG. 12 shows an example in which the format is specified by the vertical line passing through the column confirmation mark provided in the note 3 and the paragraph area is specified by the horizontal line passing through the row confirmation mark.

  Here, note 3 is set such that when a vertical line passing through the leftmost column confirmation marks 60e and 60f is entered, the left side of the vertical line is regarded as a date entry area. In addition, when a vertical line passing through the center column confirmation marks 60g and 60h is entered, it is assumed that the left side of the vertical line is regarded as a company name entry area.

  Note 3 also includes a classification designation box 80 for designating which category to classify for each paragraph. In the classification designation box 80, the user enters the alphabets A to Z using the electronic pen 10, and the user can freely determine which category the A to Z corresponds to. . It should be noted that the correspondence between the predetermined alphabet and the category can be entered on the back of the notebook. The entry in the classification designation box 80 is not limited to the alphabet, and any character or symbol can be applied as long as it is associated with the category.

  In addition, on the note 3 shown in FIG. 12, the classification designation box 80 is provided at a ratio of one to the three ruled lines. However, the present invention is not limited to this, and an arbitrary number is specified for each paragraph. If the need for entering the alphabet is high and the design permits the provision of a plurality of classification designation boxes 80 in the notebook 3, the number of classification designation boxes 80 is not limited.

  If the user wants to set up a format that divides Note 3 into three columns and enters the date and time of entry in the left column, the company name in the middle column, and the meeting contents in the right column, the electronic pen 10, the vertical lines 71 passing through the column confirmation marks 60e and 60f and the vertical lines 72 passing through the column confirmation marks 60g and 60h are entered as shown in FIG. Then, according to the set format, the user enters the date and time “2003/10/27” on the left side of the vertical line 71, the company name “ABC Association” on the left side of the vertical line 72, and the vertical line 72 Enter the contents of the meeting with ABC Association on the right. Since the content of the conference is a category corresponding to the alphabet “A”, the user enters “A” in the classification designation box 80a.

  Further, when there is a meeting with another company on the same day, as shown in FIG. 12, the user first separates the information into horizontal lines up to the vertical line 71 passing through the line confirmation mark 40r in order to divide the information into paragraphs. Enter 90. Then, in accordance with the set format, the user enters the company name “Company D” on the left side of the vertical line 72 and the content of the meeting with the D company on the right side of the vertical line 72. Since the contents of the meeting are categories corresponding to the alphabet “C”, the user enters “C” in the classification designation box 80b.

  Further, when there is a meeting with another company on the next day, as shown in FIG. 12, the user first separates the paragraphs into pieces of information by dividing the information into horizontal lines 91 passing through the line confirmation marks 40s and 40t. Fill in. Then, according to the set format, the user enters the entry date “2003/10/28” on the left side of the vertical line 71, the company name “E company” on the left side of the vertical line 72, and the E on the right side of the vertical line 72. Fill out the meeting details with the company. Since the content of the meeting is a category corresponding to the alphabet “B”, the user enters “B” in the classification designation box 80c.

  In this case, the server 5 that has acquired the entry information first refers to a coordinate table to be described later, and a vertical line 71 that passes through the column confirmation marks 60e and 60f and a vertical line that passes through the column confirmation marks 60g and 60h. Recognize that 72 is entered in note 3. Then, based on the column information set in advance, the server 5 has the notebook 3 in which the area on the left side of the vertical line 71 is a date entry area, the area on the left side of the vertical line 72 is a company name entry area, The area on the right side of the vertical line 72 is set to a format that is an area for entering information on a meeting held with the company entered in the company name entry area on the date entered in the date entry area.

  In addition, the server 5 that has acquired the entry information recognizes that the horizontal line 90 from the line confirmation mark 40r to the vertical line 71 has been entered in the note 3 with reference to a coordinate table described later. Then, the server 5 identifies the area from the beginning of the note 3 to the horizontal line 90 as the small paragraph area 82 and assigns an area ID “AM01” for identifying the area to the small paragraph area 82. Further, the server 5 recognizes that the alphabet entered in the classification designation box 80a corresponding to the small paragraph area 82 is “A”. At this time, the server 5 recognizes “A” by recognizing the entry information corresponding to the classification designation box 80a. Then, the server 5 stores the image data representing the contents described in the small paragraph area 82 and the category “A” using the area ID “AM01” as a key in the entry information DB 7 shown in FIG.

  Thus, in the above (i) to (iii), the horizontal line dividing the entry information into paragraph areas is based on the premise that both ends pass the line confirmation mark, but as in (iv) and (v), When a vertical line passing through the column confirmation mark is used in combination, a horizontal line passing through the row confirmation mark at one end and passing through the range of xmm to the left and right of the predetermined vertical line can also be applied. Thereby, although details will be described later, the entry information can be subdivided and further stored and processed as a hierarchical structure.

  Next, the server 5 recognizes that the horizontal line 91 including the line confirmation marks 40s and 40t has been entered in the note 3 by referring to a coordinate table described later based on the acquired entry information. Then, the server 5 specifies the area from the beginning of the note 3 to the horizontal line 91 as the large paragraph area 83 and assigns an area ID “AL01” for identifying the area to the large paragraph area 83. Further, the server 5 recognizes that the alphabet entered in the classification designation box 80 b corresponding to the large paragraph area 83 is “C”. Then, the server 5 stores image data representing the contents described in the large paragraph area 83 and the category “C” in the entry information DB 7 shown in FIG. 7 using the area ID “AL01” as a key. In this way, when the entry information is subdivided by the horizontal line 91 whose both ends are row confirmation marks, a horizontal line 90 whose one end is a row confirmation mark is entered between the beginning and the horizontal line 91. When the small paragraph area 82 is specified by the server 5, the server 5 specifies the area from the beginning including the small paragraph area 82 to the horizontal line 91 as the large paragraph area 83.

  Next, the server 5 refers to a coordinate table, which will be described later, based on the acquired entry information, identifies the area after entry of the horizontal line 91 as the large paragraph area 84, and identifies the area as the large paragraph area 84. Area ID “AL02” is assigned. Further, the server 5 recognizes that the alphabet entered in the classification designation box 80 c corresponding to the large paragraph area 84 is “B”. Then, the server 5 stores image data representing the contents described in the large paragraph area 84 and the category “B” in the entry information DB 7 shown in FIG. 7 using the area ID “AL02” as a key.

  In this way, when the user uses the electronic pen 10 to write on the notebook 3 by using the horizontal line whose both ends are row confirmation marks and the horizontal line whose one end is a row confirmation mark, the server 5 It is possible to subdivide the entry information and store and process each information as a hierarchical structure. Further, the subdivided storage information can be classified into a predetermined category, and the result of the classification can be associated and stored and processed.

[server]
Next, the server 5 will be described in detail. FIG. 13 shows the internal configuration of the entry information processing system 100, particularly the server 5.

  As shown in FIG. 14, the coordinate table 503 stores coordinate data, ruled lines, and column information using the confirmation mark ID and the box ID as keys. The confirmation mark ID is information for identifying the row confirmation mark and the column confirmation mark provided in the note 3, and “Lxx” is assigned to the row confirmation mark and “Cxx” is assigned to the column confirmation mark. The box ID is information for identifying the classification designation box provided in the note 3 and is assigned “Bxx”. The coordinate data is position coordinates on the note 3 indicating the area where the confirmation mark ID or the confirmation mark or the classification designation box indicated by each box is arranged. Further, the ruled line is stored only when corresponding to the line confirmation mark, and is information indicating the ratio of the ruled line on the note 3. Specifically, the ruled line “3” as shown in FIG. 14 is such that the row confirmation mark to which the confirmation mark ID “L001” is assigned is provided on the notebook 3 at a ratio of one to the three ruled lines. Represents that. The column information is stored only when it corresponds to the column confirmation mark, and what information is entered in the column on the note 3 configured by entering a vertical line passing through the column confirmation mark. It is the information which shows. The server 5 can identify the format intended by the user by referring to the column information based on the entry information.

  The line confirmation mark specifying function 505 extracts the line confirmation mark included in the entry information by referring to the coordinate table 503 based on the entry information acquired by the entry information acquisition function 502 and determines the position on the note 3. It is a function to identify. Further, it is a function of specifying a horizontal line, a diagonal line, parentheses, and a rectangle for specifying each area included in the entry information based on the line confirmation mark specifying the position.

  The crossing line specifying function 506 is a function for specifying a vertical line where one end that does not pass through the line check mark intersects, other than the line that passes through the line check mark among the horizontal lines specified by the line check mark specifying function. . In addition, when both ends are other than those that pass through the row confirmation mark and one end that does not pass through the row confirmation mark does not intersect with any vertical line, the horizontal line is not applied to the process.

  The area specifying function 507 is a function for specifying each area based on the horizontal line, the oblique line, the parenthesis, and the rectangle specified by the line confirmation mark specifying function 505 and the intersection line specifying function 506. The paragraph area specifying function 571 included in the area specifying function 507 is a function for specifying the paragraph area included in the entry information by the horizontal line specified by the line confirmation mark specifying function 505 and the intersection line specifying function 506. The large paragraph area specifying function 572 included in the paragraph area specifying function 571 is a function for specifying a large paragraph area by a horizontal line specified by the line check mark specifying function 505 and having both ends passing through the line check mark. The small paragraph area specifying function 573 specifies a small paragraph area by a horizontal line specified by the line check mark specifying function 505 and the intersection line specifying function 506, one end passing through the line check mark and the other end crossing the vertical line. It is a function.

  A deletion area specifying function 574 included in the area specifying function 507 is a function for specifying a deletion area by a hatched line specified by the line confirmation mark specifying function 505. The extraction area specifying function 575 is a function for specifying an extraction area with parentheses or a rectangle specified by the line confirmation mark specifying function.

  The column confirmation mark specifying function 509 extracts the column confirmation mark included in the entry information by referring to the coordinate table 503 based on the entry information acquired by the entry information acquisition function 502 and determines the position on the note 3. It is a function to identify.

  The format specifying function 510 is a function for specifying the format of the note 3 intended by the user based on the position of the column check mark specified by the column check mark specifying function 509 and the corresponding column information.

  The category specifying function 511 extracts the information entered in the classification designation box by referring to the coordinate table 503 based on the entry information acquired by the entry information acquisition function 502, and character-recognizes the information. This function specifies the category entered in the classification designation box. Further, the specified category is a function for associating the specified category with the paragraph area specified by the paragraph area specifying function 571.

  The entry information processing function 512 stores the image data of the contents described in the area specified by the area specifying function 507 in association with the category specified by the category specifying function 511 according to the format specified by the format specifying function 510, This is a function for performing predetermined processing. Here, the predetermined process is a process depending on the application or a process arbitrarily designated by the user.

[Entry information processing]
Next, storage processing, deletion processing, extraction processing, formatting processing, and category processing executed by the entry information processing system 100 will be described. Note that the storage process, the deletion process, the extraction process, and the formatting process can be performed independently or in parallel. In addition, the category processing can be performed alone or in parallel with the deletion processing and the extraction processing.

(I) Storage Process First, the storage process executed by the entry information processing system 100 will be described. FIG. 15 is a flowchart of the storage process. The user first enters a character string in the notebook 3 using the electronic pen 10 (step S1). Here, the character string is, for example, lecture content or conference content. Further, when the user wants to divide and subdivide the lecture contents that have been entered, the user uses the electronic pen 10 on the notebook 3 to enter horizontal lines that pass through the row confirmation mark (Δ) at both ends (step S2). Then, the entry information is transmitted to the server 5 via the terminal device 25 by entering a check mark in the transmission box on the note 3 (step S3).

  The server 5 acquires the entry information and extracts coordinate data for each stroke from the entry information (step S4). Then, the server 5 refers to the coordinate table 503 based on the extracted coordinate data for each stroke to determine whether or not the line information mark is included in the entry information (step S5). If the line information mark is not included in the entry information (step S5; No), the server 5 completes the storage process by storing the image data acquired as the entry information in the entry information DB 7 shown in FIG. S13). On the other hand, when the line confirmation mark is included in the entry information (step S5; Yes), the server 5 determines whether or not a horizontal line passing through the line confirmation mark at both ends is specified (step S6). If a horizontal line that passes through the line confirmation mark at both ends is not specified (step S6; No), the server 5 performs a deletion process or an extraction process to be described later (step S11).

  On the other hand, when a horizontal line passing through the line confirmation mark is specified at both ends (step S6; Yes), the server 5 specifies a paragraph area based on the horizontal line and assigns an area ID to the paragraph area (step S7). Further, the server 5 acquires image data corresponding to the specified paragraph area from the acquired entry information (step S8), and stores the image data in the entry information DB 7 using the assigned area ID as a key (step S9). ). Then, the server 5 determines whether or not the processing in steps S7 to S9 has been performed on all the horizontal lines included in the entry information (step S10). If not, the processing is repeated. On the other hand, if so, the storage process is completed.

  As described above, according to the storage process, when the user uses the electronic pen 10 to write a line passing through the two row confirmation marks on the notebook 3, the server 5 is separated by the line. The area can be specified as a paragraph area, and the contents described in the paragraph area can be stored in the entry information DB 7 using the area ID as a key. That is, it becomes possible to subdivide and store the entry information in accordance with the user's intention.

(Ii) Deletion Process Next, the deletion process executed by the entry information processing system 100 will be described. FIG. 16 is a flowchart of the deletion process. The user first enters a character string in the notebook 3 using the electronic pen 10. Here, if the content of the character string is incorrect and the user wishes to delete it, the user enters two diagonal lines that pass through the line confirmation mark for the erroneous content on the note 3. . Then, by filling a check mark in the transmission box on the note 3, the entry information is transmitted to the server 5 via the terminal device 25.

  The server 5 acquires the entry information and extracts coordinate data for each stroke from the entry information (step S24). Then, the server 5 refers to the coordinate table 503 based on the extracted coordinate data for each stroke, and determines whether or not a line confirmation mark (Δ) is included in the entry information (step S25). When the line information mark is not included in the entry information (step S25; No), the server 5 completes the storage process by storing the image data acquired as the entry information in the entry information DB 7 shown in FIG. S35). On the other hand, when the line confirmation mark is included in the entry information (step S25; Yes), the server 5 determines whether or not diagonal lines passing through the line confirmation mark are specified at both ends (step S27). If the diagonal lines that pass through the line confirmation mark at both ends are not specified (step S26; No), the server 5 performs a storage process or an extraction process (step S31).

  On the other hand, when a diagonal line that passes through the row confirmation mark is identified at both ends (step S26; Yes), the server 5 identifies a deletion area based on the diagonal line, and whether or not there are two diagonal lines indicating the deletion area. Is determined (step S28). When there are not two diagonal lines indicating the deletion area (step S28; No), the server 5 performs gray-out processing on the image data corresponding to the deletion area (step S32). That is, processing is performed so that the user cannot operate the image data. Further, the server 5 assigns an area ID to the deletion area, and stores the image data in the entry information DB 7 using the area ID as a key (step S33).

  On the other hand, when there are two diagonal lines indicating the deletion area (step S28; Yes), the server 5 deletes the image data corresponding to the deletion area from the entry information (step S29). Then, the server 5 determines whether or not the processing of steps S27 to S30 has been performed for all the oblique lines included in the entry information (step S30), and if not, the processing is repeated. On the other hand, if so, the deletion process is completed.

  As described above, according to the deletion process, the user uses the electronic pen 10 to enter the diagonal line passing through the two line confirmation marks on the note 3 so that the server 5 is surrounded by the line confirmation marks. The area can be identified as a deletion area, and the contents described in the deletion area can be deleted from the acquired entry information.

(Iii) Extraction Processing Next, extraction processing executed by the entry information processing system 100 will be described. FIG. 17 is a flowchart of the extraction process. The user first enters a character string in the notebook 3 using the electronic pen 10. Here, when the user wants to extract the contents of the character string and perform a predetermined process, the user can use parentheses or line confirmation that both ends pass line confirmation marks for the content to be extracted on the note 3. Fill in a square that passes 3 or more marks. Then, by filling a check mark in the transmission box on the note 3, the entry information is transmitted to the server 5 via the terminal device 25.

  The server 5 acquires the entry information and extracts coordinate data for each stroke from the entry information (step S41). Then, the server 5 refers to the coordinate table 503 based on the extracted coordinate data for each stroke, and determines whether or not a line confirmation mark (Δ) is included in the entry information (step S42). When the line information mark is not included in the entry information (step S42; No), the server 5 completes the storage process by storing the image data acquired as the entry information in the entry information DB 7 shown in FIG. S49). On the other hand, when the entry information includes a line confirmation mark (step S42; Yes), the server 5 determines whether or not a bracket that passes through the line confirmation mark at both ends or a quadrangle that passes through three or more line confirmation marks is specified. Is determined (step S43). If the parentheses passing through the line confirmation mark or the quadrangle passing through the three or more line confirmation marks are not specified (step S43; No), the server 5 performs a storage process or a deletion process (step S47).

  On the other hand, when a bracket that passes through the line confirmation mark or a square that passes through three or more line confirmation marks is identified (step S43; Yes), the server 5 identifies the extraction area based on the bracket or the square ( Step S44). Furthermore, the server 5 acquires image data corresponding to the specified extraction area from the entry information, and performs a predetermined process on the image data (step S45). Then, the server 5 determines whether or not the processing of steps S44 and 45 has been performed on all parentheses or squares included in the entry information (step S46), and if not, repeats the processing. On the other hand, if so, the extraction process is completed.

  As described above, according to the extraction process, the server 5 uses the electronic pen 10 to write on the notebook 3 a line that passes through three or more line confirmation marks so as to surround a specific area. The area indicated by the line confirmation mark can be specified as the extraction area, and a predetermined process can be performed on the contents described in the extraction area.

(Iv) Format Processing Next, format processing executed by the entry information processing system 100 will be described. FIG. 18 is a flowchart of the format process. When the user wants to set the note 3 to an arbitrary format, first, a vertical line passing through the column confirmation mark (O) is entered according to the column information (step S71). Further, the user uses the electronic pen to enter a character string in accordance with the format (step S73). Then, by filling a check mark in the transmission box on the note 3, the entry information is transmitted to the server 5 via the terminal device 25.

  The server 5 acquires the entry information and extracts coordinate data for each stroke from the entry information (step S74). Then, the server 5 refers to the coordinate table 503 based on the extracted coordinate data for each stroke, and determines whether or not the column information mark is included in the entry information (step S75). When the column information mark is not included in the entry information (step S75; No), the server 5 completes the storage process by storing the image data acquired as the entry information in the entry information DB 7 shown in FIG. S81). On the other hand, when the column confirmation mark is included in the entry information (step S75; Yes), the server 5 identifies the vertical line passing through the column confirmation mark and sets it on the note 3 based on the vertical line and the column information. The specified format is specified (step S76). Then, the server 5 determines whether or not the process of step S76 has been performed on all the vertical lines included in the entry information (step S77). If not, the process is repeated. On the other hand, if it is performed, image data is acquired from the entry information in accordance with the specified format (step S78). Then, the format processing is completed by storing the acquired image data in the entry information DB 7 (step S79).

  As described above, according to the format process, the server 5 sets the vertical line passing through the column confirmation mark on the notebook 3 by using the electronic pen 10 so that the server 5 is set in advance in association with the column confirmation mark. Based on the column information, the format intended by the user can be grasped, and the processing according to the format can be performed on the entry information. That is, the user can easily set an arbitrary format.

(V) Category Processing Next, category processing executed by the entry information processing system 100 will be described. FIG. 19 is a flowchart of category processing. When the user wants to set the note 3 to an arbitrary format, first, a vertical line passing through the column confirmation mark is written according to the column information. Further, the user uses the electronic pen 10 to enter a character string in accordance with the format. At this time, when the user wants to divide and subdivide the contents of the entered character string, the user uses the electronic pen 10 on the notebook 3 to enter horizontal lines that pass through the row confirmation mark at both ends or one end. Further, the user enters the category of each subdivided paragraph in the corresponding classification designation box. Then, by filling a check mark in the transmission box on the note 3, the entry information is transmitted to the server 5 via the terminal device 25.

  The server 5 acquires the entry information and extracts coordinate data for each stroke from the entry information (step S91). Then, the server 5 refers to the coordinate table 503 based on the extracted coordinate data for each stroke, and determines whether or not the column confirmation mark (◯) is included in the entry information (step S92). When the column confirmation mark is not included in the entry information (step S92; No), the server 5 proceeds to step S95. On the other hand, when the column confirmation mark is included in the entry information (step S92; Yes), the server 5 identifies the vertical line passing through the column confirmation mark and sets it on the note 3 based on the vertical line and the column information. The specified format is specified (step S93). Then, the server 5 determines whether or not the process of step S93 has been performed on all the vertical lines included in the entry information (step S94). If not, the process is repeated.

  On the other hand, if it is performed, it is determined by referring to the coordinate table 503 based on the extracted coordinate data for each stroke, whether or not a line confirmation mark (Δ) is included in the entry information (step S95). ). When the line confirmation mark is not included in the entry information (step S95; No), the server 5 is entered in the classification designation box by referring to the coordinate table 503 based on the extracted coordinate data for each stroke. The entry information is acquired as classification entry information, and the category is specified by character recognition of the classification entry information (step S110). Further, the server 5 associates the image data acquired as entry information with the specified category and stores it in the entry information DB 7 shown in FIG. 7 (step S111), and completes the category processing.

  On the other hand, when the line confirmation mark is included in the entry information (step S95; Yes), the server 5 determines whether or not a horizontal line passing through the line confirmation mark at both ends is specified (step S96). When the horizontal line that passes through the row confirmation mark is not identified at both ends (step S96; No), the server 5 identifies the vertical line that is located at the other end of the horizontal line that passes through the row confirmation mark (step S103). Then, the server 5 identifies a small paragraph area based on the position coordinates of the line confirmation mark through which one end of the horizontal line passes, and assigns an area ID to the small paragraph area (step S104). If the vertical line located at the other end cannot be specified even if the horizontal line passes through the row confirmation mark, category processing is performed assuming that the horizontal line does not exist. Here, the case where the vertical line cannot be specified is a case where there is no end of the horizontal line within xmm on the left and right of all the vertical lines. Then, the server 5 performs the process of step S98. On the other hand, when a horizontal line that passes through the line confirmation mark is specified at both ends (step S96; Yes), the server 5 identifies a large paragraph area based on the position coordinates of the line confirmation mark through which the horizontal line passes, and the large paragraph area An area ID is assigned to (step S97). Furthermore, the server 5 acquires the entry information entered in the classification designation box corresponding to each paragraph area as the classification entry information by referring to the coordinate table 503 based on the extracted coordinate data for each stroke, A category is specified by character recognition of the classification entry information (step S98). Then, the server 5 acquires image data corresponding to each paragraph area identified in steps S97 and S10 according to the format identified in step S93 (step S99). Further, the server 5 stores the image data corresponding to each paragraph area in the entry information DB 7 in association with the category specified in step S98 (step S100). Then, the server 5 determines whether or not the processing of steps S96 to S100 has been performed on all the horizontal lines included in the entry information (step S101). If not, the processing is repeated. On the other hand, if so, the category process is completed.

  As described above, according to the category processing, the user uses the electronic pen 10 to fill in the note 3 by using the horizontal line whose both ends are row confirmation marks and the horizontal line whose one end is a row confirmation mark. Thus, the server 5 can subdivide the entry information and store and process each information as a hierarchical structure.

  In the present embodiment, entry information is subdivided in category processing, and the paragraph area when storing in a hierarchical structure is two types of large paragraph and small paragraph, but the present invention is not limited to this, It can be arbitrarily set, and a hierarchical structure with a plurality of types of paragraph areas can be configured according to the format.

  Further, in this embodiment, the row confirmation mark and the column confirmation mark are provided on the notebook 3 with the configuration as shown in FIG. 8, but the present invention is not limited to this and is arbitrarily set. It is possible. Therefore, in the present embodiment, the line indicating the paragraph area is a horizontal line, but the paragraph dividing line indicating the paragraph area is not limited to the horizontal line but may be a diagonal line or the like. Similarly, the line indicating the format is a vertical line, but the format designation line indicating the format is not limited to the vertical line, and may be a diagonal line or the like.

  With this entry information processing system, entry information entered by a user in a notebook that is not divided into a plurality of items can be easily and accurately divided and processed based on the user's intention.
