Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique capable of accurately acquiring information entered with an electronic pen.
[0002]
[Prior art]
Conventionally, users have filled in the necessary items such as application forms submitted to government agencies, financial institutions, private companies and others (hereinafter referred to as “various application documents”) using a ballpoint pen, etc. The documents were submitted. On the other hand, in recent years, electronic forms obtained by digitizing forms have been used in place of conventional paper forms. The electronic form is electronic data including a plurality of fields such as paper form entries. A user who creates a form reads an electronic form on a personal computer or the like and displays it on a display device, and inputs necessary items on the electronic form by operating an input device such as a keyboard or a mouse. The input items are acquired as electronic data and can be transmitted to the organization to which the form is submitted through a network or the like.
[0003]
However, when preparing various application documents to be submitted to public offices, financial institutions, private companies, etc., for users who do not have enough knowledge about how to operate personal computers, users who are not good at keyboard input, etc. It is often difficult to use the above-mentioned electronic form well. For such users, the method of pen input to a paper form is the easiest, as is conventionally done.
[0004]
In recent years, pen-type input devices called “electronic pen”, “digital pen”, and the like have appeared as effective input devices in such cases (hereinafter, referred to as “electronic pen” in this specification). A representative example is “Anot pen” developed by Swedish company Anoto. Anotopen is used in a pair with dedicated paper (hereinafter referred to as “dedicated paper”) on which a predetermined dot pattern is printed. In addition to the normal ink-type pen tip, the Anoto pen is equipped with a small camera for reading the dot pattern on the dedicated paper and a data communication unit. When a user writes characters on the special paper with an anotopen or checks an image that is designed on the special paper, the small camera detects the dot pattern on the special paper as the pen moves, and the user Entry data (also referred to as “stroke data”) such as written characters and images is acquired. This entry data is transmitted from the Anotopen to a terminal device such as a nearby personal computer or mobile phone by the data communication unit. The system using this anotopen can be used as an input device in place of the keyboard, and is very easy to use for users who are reluctant to use the personal computer and keyboard described above. On the other hand, even at the submission site of various application documents such as government offices, user entries can be obtained as entry data rather than as paper documents as before, so electronic processing is then performed directly by the server etc. There is a merit that it can be done.
[0005]
In the system as described above, the user creates an application document using an electronic pen, and fills in the entry data corresponding to the entry items on the application document via the terminal device near the electronic pen via the network. Send to. On the other hand, the submission server creates an application form based on the received entry data and performs necessary reception processing.
[0006]
[Problems to be solved by the invention]
Normally, application documents and the like include items for a user to enter a check mark with an electronic pen. Here, it is desirable that the check mark entered by the user is entered so as to fit within the item, but since it is handwritten with an electronic pen, part of the check mark often protrudes from the item. Therefore, when multiple items are provided on the same application document, the check mark is applied to two items, and it is not possible to accurately identify which item the user has selected and filled in with the check mark. It was difficult.
[0007]
In addition, when a user enters a check mark in an item and then enters an oblique line indicating cancellation on the check mark, it is difficult to distinguish the check mark from the oblique line. In other words, it has been difficult to accurately specify which item the check mark entered by the user has been canceled.
[0008]
The present invention has been made in view of the above points, and can easily and accurately identify an item selected by a user and filled with a check mark and / or an item canceled by the user. It is an object to provide an item identification system capable of acquiring information.

DETAILED DESCRIPTION OF THE INVENTION
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 invention will be described.
[0022]
[Electronic pen]
FIG. 1 is a diagram schematically showing how the electronic pen is used, and FIG. 2 is a functional 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.
[0023]
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.
[0024]
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.
[0025]
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.
[0026]
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 / Y coordinates on the dedicated paper 20 from the supplied dot pattern.
[0027]
The processor 11 acquires the writing pressure array data and the X / Y coordinate data while the description of the user is performed, and stores them in the memory 12 in association with the 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.
[0028]
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.
[0029]
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.
[0030]
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.
[0031]
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.
[0032]
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.
[0033]
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.
[0034]
In the data communication unit 13 in the above example, data transmission from the electronic pen 10 to the terminal device 25 is performed by various methods such as Bluetooth wireless transmission, wired transmission using a USB cable, and data transmission by contact with a terminal. It is possible to do it.
[0035]
Next, a method for acquiring X / 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.
[0036]
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.
[0037]
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. Note that the minimum unit for recognizing a dot pattern is 2 mm × 2 mm, and the camera 16 captures about 100 times per second.
[0038]
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.
[0039]
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.
[0040]
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.
[0041]
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.
[0042]
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.
[0043]
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.
[0044]
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.
[0045]
In the present specification, the term “printing” has a concept including not only normal printing but also printing by a printer.
[0046]
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.
[0047]
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 an item specifying server described later also serves as the inquiry server 26 and the service server 27.
[0048]
[Item identification system]
Next, the item specifying system of the present invention will be described. FIG. 7 shows a schematic configuration of the item identification system 100. The item specifying system 100 shown in FIG. 7 acquires accurate information by specifying an item selected by a user and filled with a check mark.
[0049]
As shown in FIG. 7, the item specifying system 100 is configured by connecting the terminal device 25 and the item specifying server 5 through the network 2. Here, one suitable example of the network 2 is the Internet. The terminal device 25 is a terminal capable of transmitting and receiving data via a network such as a personal computer (hereinafter referred to as “PC”) used by a user or a mobile phone. The item specifying server 5 is connected to a user database (hereinafter referred to as “DB”) 51.
[0050]
First, the outline of the item identification method by this system is described. First, the user selects an arbitrary item provided on the application form 3 using the electronic pen 10 and enters a check mark in the item. The entry data entered by the user is transmitted from the electronic pen 10 to the terminal device 25 and transmitted from the terminal device 25 to the item specifying server 5.
[0051]
The item specifying server 5 extracts the coordinate data for each stroke from the entry data based on the coordinate data of the dot pattern printed on the application form 3. Here, the stroke is a check mark or the like entered by the user using the electronic pen 10 in one operation, that is, with a single stroke. Then, the item specifying server 5 sets a reference based on the extracted coordinate data of the stroke, and acquires information on the item selected by the user and filled with a check mark by referring to the coordinate table based on the reference. Furthermore, the item specifying server 5 stores information on the items acquired in the user DB 51 using the pen ID included in the entry data as a key. According to this, the item specifying server 5 can collectively manage the information related to the items selected by the user and filled in with the check mark by the user DB 51 and easily collect the information related to the items. In the present invention, it is assumed that the user always fills out the application form 3 using the specific electronic pen 10. According to this, the item specifying server 5 can specify the user based on the pen ID that is the identification information of the electronic pen 10.
[0052]
Next, each component will be described individually. First, the application form 3 will be described. In the system of the present invention, the application form 3 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 predetermined characters and items are 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 characters and items is printed with normal (not including carbon) ink, the electronic pen 10 does not recognize it.
[0053]
An example of the application form 3 is shown in FIG. As shown in the figure, the application form 3 is printed by a question item 40, a plurality of answer items 41 to 45 corresponding to the answer to the question, sex items 46 and 47, marriage items 48 and 49, and a transmission instruction unit 79. Has been. The plurality of items 41 to 49 and the transmission instruction unit 79 are printed with respect to position coordinates on a preset dot pattern. That is, the plurality of items 41 to 49 and the transmission instruction unit 79 are defined by the position coordinates (XY coordinates) of the application form 3. The transmission instruction unit 79 corresponds to a transmission box for transmitting the transmission command described above.
[0054]
The arrangement of the items 41 to 49 shown in FIG. 8A is schematically shown in FIG. As understood from FIGS. 8A and 8B, answer items 41 to 45 are area numbers A1 to A5, gender items 46 and 47 are area numbers B1 and B2, and marriage items 48 and 49 are area numbers B3 and B3. This area is B4 and is printed in correspondence with the position coordinates on the dot pattern set according to the size and the like. That is, the areas of the area numbers A1 to A5 and B1 to B4 are defined by the position coordinates (XY coordinates) of the application form 3. The area number is information for identifying the area. For example, the area of area number A1 is a range defined by coordinates (x1, y1) to coordinates (x2, y2).
[0055]
When the user fills in the application form 3 using the electronic pen 10, the electronic pen 10 generates data indicating which coordinates of the application form 3 have been written based on the dot pattern, and stores the internal memory. 12 to store. Accordingly, in the application form 3 illustrated in FIG. 8A, when the user enters a check mark in the answer item 41, for example, the electronic pen 10 acquires the entry position coordinates of the application form 3 and stores it in the memory 12. . When the user enters a check mark in the transmission instruction unit 79 provided on the application form 3, the entry position coordinates stored in the memory 12 are entered from the electronic pen 10 to the predetermined terminal device 25 as entry data. Sent. That is, “train” is selected as the answer to the question item 40 described in the application form 3, and entry data including information that a check mark is entered in the answer item 41 is transmitted to the item specifying server 5.
[0056]
An example in which a check mark is entered in the application form 3 is shown in FIGS. As illustrated, the user selects answer item 41 “train” as an answer to question item 40 “transportation”, and answer item 44 “YES” as an answer to question item 40 “commuting time 1 hour or longer?” Suppose that a check mark is entered for each item. Further, it is assumed that the user is a married woman, and a check mark is entered in the sex item 47 and the marriage item 48. In addition, since the entry by the user is performed freehand using the electronic pen 10, as shown in FIGS. 9A to 9C, the check mark does not fit within the item selected by the user, It may affect items that are not selected. In this case, the item specifying server 5 that has acquired the entry data from the electronic pen 10 sets the check mark start point position coordinates, intermediate reference point position coordinates, and the like as a reference, and selects the item selected by the user based on the reference. Identify. Therefore, a method for the item specifying server 5 to specify an item selected by the user based on check marks applied to a plurality of items will be described below with reference to FIGS. 10 to 13.
[0057]
First, with reference to FIG. 9A and FIG. 10, a method for specifying an item based on the start point position coordinates of the check mark will be described. As shown in FIG. 9A, the start point of the check mark is included in the item selected by the user, but the part other than the start point of the check mark is applied to the item not selected by the user. The item specifying server 5 specifies an item by referring to the coordinate table with reference to the position coordinates of the start point. That is, the item specifying server 5 specifies the item having the closest position coordinate of the start point set as the reference as the item selected by the user.
[0058]
Specifically, the check mark 61 shown in FIG. 10 covers both the answer items 42 and 44, but the item including the position coordinates of the start point 62 is the answer item 44. Therefore, the item specifying server 5 specifies that the answer item 44 that means “YES” is an item selected by the user as an answer to the question item 40 “commuting time 1 hour or more?”. Further, although the check mark 63 protrudes from the marriage item 48, the item including the position coordinates of the start point 64 is the marriage item 48. Therefore, the item identification server 5 identifies the marriage item 48 that means that the user is “married” as the item selected by the user.
[0059]
Next, with reference to FIG. 9B and FIG. 11, a method for specifying an item based on the specific gravity of the line length of the check mark will be described. As shown in FIG. 9B, when the check mark is applied to a plurality of items, the item specifying server 5 refers to the coordinate table based on the specific gravity of the line length of the check mark applied to each item. To identify the item.
[0060]
Specifically, the check mark 70 shown in FIG. 11 covers both the answer items 42 and 44. In this case, the item specifying server 5 first calculates the line segment length A of the check mark 70 applied to the answer item 44 based on the position coordinates of the intersections 65 and 66 between the check mark 70 and the answer item 44. Then, the item identification server 5 calculates the line segment length B of the check mark 70 applied to the answer item 42 based on the position coordinates of the intersection 67 between the check mark 70 and the answer item 42 and the end point 68 of the check mark 70. To do. Further, the item specifying server 5 compares the line segment lengths A and B and specifies that the item corresponding to the longer one, that is, the item having the greater specific gravity of the line segment length of the check mark 70 is the item selected by the user. To do. Similarly, the check mark 71 is applied to both the marriage items 48 and 49, but since the line segment specific gravity is larger in the marriage item 48, the item specifying server 5 is the item selected by the user. Identifies it.
[0061]
Next, with reference to FIG. 9C and FIG. 12, a method for specifying an item based on the coordinates of the intermediate reference point position of the check mark will be described. As shown in FIG. 9C, when the check mark covers a plurality of items, the item specifying server 5 sets the position coordinates of the middle point of the check mark as an intermediate reference point, and based on the intermediate reference point. The item is specified by referring to the coordinate table. That is, the item specifying server 5 specifies the item having the closest position coordinate of the midpoint set as the intermediate reference point as the item selected by the user.
[0062]
Specifically, as shown in FIG. 12, the check mark 80 covers both the answer items 42 and 44. In this case, the item specifying server 5 first checks the check mark 80 based on the position coordinates of the end points 81 and 83 on the X axis of the check mark 80 and the position coordinates of the end points 82 and 83 on the Y axis. The position coordinates of the point 84 are calculated. Then, the item specifying server 5 sets the position coordinates of the midpoint 84 as an intermediate reference point, and specifies an item by referring to the coordinate table based on the intermediate reference point. That is, the item closest to the position coordinate of the midpoint 84 set as the intermediate reference point is specified as the item selected by the user.
[0063]
Furthermore, with reference to FIG. 9C and FIG. 12, a method for specifying an item on the basis of the inversion point 82 where the check mark vector is inverted will be described.

Identify items. That is, the item identification server 5 identifies the item selected by the user as the item having the closest position coordinates of the inversion point set as the reference. The inversion point means the direction of the stroke entered by the user on the X axis or the Y axis, that is, the point where the vector is inverted. Specifically, the check mark 80 is bent as indicated by a point 82 in FIG. It is a point that hits the corner.
[0064]
Specifically, as shown in FIG. 12, the check mark 80 covers both the answer items 42 and 44. In this case, the item specifying server 5 first acquires the position coordinates of the reversal point 82 where the direction of the stroke is reversed on the Y axis. Then, the item identification server 5 identifies the item by referring to the coordinate table based on the position coordinates of the inversion point 82. That is, the item specifying server 5 specifies that the item selected by the user is the item closest to the position coordinates of the inversion point 82 set as the reference.

Specifically, the reference is, as described above, the position coordinates of the start point of the stroke, the position coordinates of the intermediate reference point, the position coordinates of the inversion point, the line segment length, and the like.
[0070]
The item specifying function 506 is a function for specifying the item selected by the user by executing the item specifying program 501 and referring to the coordinate table 505 based on the reference set by the reference setting function 504. Here, the coordinate table 505 will be described with reference to FIG. The coordinate table 505 includes area numbers, area coordinate data, and item contents. The area number is information for identifying each area on the application form 3 as shown in FIG. 8B, and the area coordinate data is the position coordinates of the application form 3 indicating the arrangement of each area. The item content represents the content of each area indicated by the area coordinate data. According to this, the area of area number B3 represents “married” and the area of area number B4 represents “unmarried”. Will be shown. Specifically, the item specifying function 506 of the item specifying server 5 compares the reference set by the reference setting function 504 with the area coordinate data of the coordinate table 505 to specify the item selected by the user and filled with a check mark. And the contents of the item can be acquired.
[0071]
The information storage function 507 executes the item specifying program 501 to acquire information related to the item specified by the item specifying function 506, and stores the information in the user DB 51 using the pen ID acquired from the entry data as a key. It is. Here, the user DB 51 will be described. The user DB 51 is composed of a pen ID and item information, and stores information related to the acquired item using a pen ID that can identify the user as a key. According to this, the item specifying server 5 can collectively manage information related to the items acquired by the user's entry, and by referring to the user DB 51, it is easy to collect data related to the items at any timing. Can be created.
[0072]
[Item identification processing]
Next, an item specifying process executed by the item specifying system 100 will be described. FIG. 15 is a flowchart of the item specifying process.
[0073]
First, the user selects an arbitrary item from among a plurality of items constituting the application form 3 and enters a check mark in the item using the electronic pen 10.

Further, by entering a check mark in the sex item 47 and the marriage item 48, the user's own gender is entered. Then, the entry data is transmitted to the item specifying server 5 through the terminal device 25 by filling a check mark in the transmission instruction section 79 on the application form 3.
[0074]
The item identification server 5 acquires entry data (step S1). Then, the item specifying server 5 extracts coordinate data for each stroke from the acquired entry data (step S2). That is, the item specifying server 5 acquires coordinate data for each check mark from the entry data. Furthermore, the item specifying server 5 sets a reference for specifying the item selected by the user based on the extracted coordinate data (step S3). Specifically, the reference is, as described above, the position coordinates of the start point of the stroke, the position coordinates of the intermediate reference point, the position coordinates of the inversion point, the line segment length, and the like. And the item specific server 5 specifies the item which the user selected by referring to a coordinate table based on the set reference | standard, and acquires the information regarding the said item (step S4).
[0075]
Next, the item specifying server 5 acquires a pen ID included in the entry data. And the item specific server 5 memorize | stores the information regarding the item specified using pen ID as a key in user DB51 (step S5). Furthermore, the item specifying server 5 determines whether or not to create aggregate data for information relating to the item (step S6). When the total data is not created, the item specifying server 5 repeats steps S1 to S6. On the other hand, when creating aggregate data, the item specifying server 5 creates aggregate data based on the user DB 51 (step S7). Thus, the item specifying process ends.
[0076]
According to this, even if the check mark entered by the user using the electronic pen 10 covers a plurality of items provided on the application form 3, the item selected by the user can be easily selected. It can be accurately identified. Therefore, the item specifying server 5 can easily acquire accurate information and use the information.
[0077]
[Modification]
In the above embodiment, in the cases as shown in FIGS. 9B and 11, the items are specified based on the specific gravity of the line length of the check mark. However, the present invention is not limited to this, and the item may be specified based on the number of sampling points constituting the check mark. Here, a sampling point is a dot which comprises the stroke which the user entered using the electronic pen 10 as shown in FIG.3 and FIG.4. Usually, the more sampling points, the longer the line segment length, and the fewer sampling points, the shorter the line segment length. In the case of this item specifying method, the item specifying server 5 calculates the number of sampling points constituting the check mark. Then, the item specifying server 5 specifies, based on the calculated number of sampling points and the coordinate table, the item containing the most sampling points as the item selected by the user.
[0078]
Further, in the above embodiment, in the case as shown in FIG. 9C and FIG. 12, based on the position coordinates of the end points 81 and 83 on the X axis and the position coordinates of the end points 82 and 83 on the Y axis. A midpoint is calculated, and the calculated midpoint is set as an intermediate position coordinate. However, the present invention is not limited to this, and only the longest line segment among a plurality of line segments constituting the check mark may be considered. For example, in the above example, the midpoint may be calculated based only on the position coordinates of the end point 82 and the end point 83, and the calculated midpoint may be set as the intermediate position coordinate. Furthermore, in the above embodiment, the middle point of the check mark 80 is set to the intermediate position coordinate in the case of FIG. 9C and FIG. 12, but the present invention is not limited to this, The center of gravity of the check mark 80 may be set as the intermediate position coordinate. Specifically, the barycentric point is calculated by averaging the X coordinate and Y coordinate of the check mark start point 81, inversion point 82, and end point 83. In other words, in the present invention, either the midpoint or the center of gravity of the check mark 80 may be set as the intermediate reference point serving as a reference for specifying the selection item.
[0079]
Further, although not particularly described in the above embodiment, the stroke extracted by the item specifying server 5 from the entry data by the stroke extraction function 503 may only have a certain length. In this case, specifically, the stroke extraction function 503 determines whether or not the stroke included in the entry data is equal to or longer than a certain length, and the coordinates of the stroke whose determination result is equal to or longer than the certain length. Extract data only. According to this, even if the user uses the electronic pen 10 to perform a single operation, that is, a stroke written with a single stroke, those having a certain length or less are not considered when specifying an item. That is, if the user does not intend to fill in the electronic pen 10 ink on the application form 3 due to a user's flaw or mistake, the stroke extraction function 503 does not extract the appropriate information. The item selected by the user in consideration of only the stroke can be specified.
[0080]
The processor 11 of the electronic pen 10 stores the user's entry in the memory 12 in association with the time stamp (time information) as described above. Therefore, the data that the electronic pen 10 transmits to the predetermined terminal device 25 includes not only the entry data but also the time data based on the time stamp in which the entry data is entered, and when the item selected by the user is specified. Information on time series may be taken into consideration.
[0081]
In the above embodiment, the item specifying program 501 and the functions 502 to 507 are held by the item specifying server 5. However, the present invention is not limited to this, and the electronic pen 10 or the terminal device 25 is not limited thereto. May be owned by According to this, the information regarding the item selected by the user can be accurately acquired and used only by the terminal device 25 without using the item specifying server 5.
[0082]
[Application example]
In the above-described embodiment, the process is described in which the item specifying server 5 accurately specifies the item selected by the user when one check mark covers a plurality of items constituting the application form 3. . The present invention is applied to the process of accurately specifying the item canceled by the user when the item is canceled by applying the item specifying server 5 and writing a diagonal line on the check mark. It is also possible to do.
[0083]
With reference to FIG. 16, a method will be described in which the item specifying server 5 specifies an item canceled by the user. The item specifying server 5 first determines whether one item includes a plurality of strokes based on the coordinate data of the stroke extracted by the stroke extraction function 503 and the coordinate table 505. When the item specifying server 5 includes a plurality of strokes in one item, the item specifying server 5 specifies that the item is an item canceled by the user.
[0084]
Specifically, as shown in FIG. 16, when a check mark is entered in the answer item 44 and, further, hatched lines 94 and 95 are entered on the check mark 93 of the answer item 45, the item specifying server 5 Check marks 91 and 93 and oblique lines 94 and 95 are extracted from the data as strokes. That is, the coordinate data of the check marks 91 and 93 and the oblique lines 94 and 95 are extracted. Furthermore, the item specifying server 5 refers to the coordinate table 505 based on the extracted coordinate data, and determines whether each of the answer items 44 and 45 includes a plurality of strokes. As a determination result, the item specifying server 5 acquires that the number of strokes included in the answer item 44 is singular and the number of strokes included in the answer item 45 is plural. Then, the item specifying server 5 specifies that the answer item 45 including a plurality of strokes is an item canceled by the user. Therefore, the item specifying server 5 recognizes that the user has selected the answer item 44 and filled in the check mark as the answer to the question item 40, and stores “YES”, which is information on the answer item 44, in the user DB 51. .
[0085]
According to this, even if the user cancels the check mark entered using the electronic pen 10, the canceled item can be easily identified. Therefore, the item specifying server 5 can acquire accurate information and use the information.
[0086]
【The invention's effect】
