  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[System configuration of electronic pen system]
FIG. 1 is a system configuration diagram of an electronic pen system 10 according to the present embodiment. As shown in FIG. 1, the electronic pen system 10 includes answer sheets (entry sheets) 5A, 5B,... (5) distributed to a plurality of participants (students) and answers (handwriting) on the answer sheet 5. The electronic pens 1A, 1B,... (1) for transmitting the entered information to the outside by a wireless communication method such as Bluetooth (registered trademark) and the entry information transmitted from each electronic pen 1 are received. And an aggregation device (terminal device) 2 for displaying entry contents and the like on a display (display means).

  In FIG. 1, the aggregation device 2 receives the entry information directly from the electronic pens 1 </ b> A and 1 </ b> B. However, since there are many answer sheets 5 to be filled in, the number of electronic pens 1 to which the entry information is transmitted is small. When there are many cases, or when the place where the answerer answers is out of the range of wireless communication due to a remote location, etc., the aggregation device 2 relays the entry information transmitted from the other electronic pens 1C, 1D,. A transfer device 3 for transferring to is provided. At this time, transmission of data from the transfer device 3 to the aggregation device 2 may be performed by a TCP / IP communication method via a LAN, for example. An electronic pen can be used for each electronic pen 1, and a laptop personal computer or the like can be used for the aggregation device 2 or the transfer device 3. The projector 4 is a device that receives display information from the aggregation device 2 and projects and displays the screen of the aggregation device 2 on the screen 6.

[Answer sheet]
The answer sheet (entry form) 5 will be described with reference to FIG. On each answer sheet 5, a dot pattern (coded pattern) having the same pattern (indicating the same coordinate range) is printed on substantially the entire surface, and user areas 501 and 502 are defined thereon. That is, the coordinate range indicated by the dot pattern in the user area 501 of each answer sheet (entry sheet) 5 is the same, and similarly, the coordinate range indicated by the dot pattern in the user area 502 of each answer sheet (entry sheet) 5 Are the same (the coordinate ranges shown in the dot patterns of the user area 501 and the user area 502 are different and there is no overlapping range portion).

  The user area 501 is an area where the electronic pen 1 is used for entry. Specifically, in the user area 501, questions and the like are printed, and a column for entering answers, a column for entering affiliation (class) and name, and the like are provided. A user area 502 is an area used for associating the pen ID with the user ID, and characters such as “registration” are printed thereon. The entrant (student) taps the user area 502 of the answer sheet 5 with the pen tip portion 103 of the electronic pen 1 when his / her name is presented in a pen setting message to be described later (see FIG. 11). Dab). The dot pattern is printed with ink containing carbon that absorbs infrared rays, and lines and characters such as entry fields and problem contents are printed with ink that does not absorb in the infrared region.

  The user area 501 is an example of the “first area” in the present invention, and hereinafter, the user area 501 may be referred to as an “answer column”. The user area 502 is an example of the “second area” in the present invention, and the user area 502 may be referred to as a “registration column” in the following.

[Dot pattern]
Next, an Anoto dot pattern (coded pattern) printed on the answer sheet 5 will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram for explaining the relationship between the dots of the dot pattern printed on the answer sheet 5 and the values to which the dots are converted. As shown in FIG. 3, each dot of the dot pattern is associated with a predetermined value depending on its position. In other words, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left, or right is shifted from the reference position of the grid (intersection of the vertical line and horizontal line). The value of each dot can be further converted into a first bit value for the X coordinate and a second bit value for the Y coordinate. The position coordinates on the answer sheet 5 are determined by the combination of the information thus associated.

  FIG. 4A shows an arrangement of a certain dot pattern. As shown in FIG. 4A, 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a 6 × 6 dot from any part on the answer sheet 5 has a unique pattern. Has been. The dot pattern formed by these 36 dots holds the position coordinates (for example, where the dot pattern is on the answer sheet 5). FIG. 4B is a diagram in which each dot shown in FIG. 4A is converted into a corresponding value based on the regularity shown in FIG. 3 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 1 that captures an image of a dot pattern.

[Electronic pen]
Next, the electronic pen 1 will be described with reference to FIG. FIG. 5 is a schematic view showing the structure of the electronic pen 1. As shown in FIG. 5, the electronic pen 1 includes an ink cartridge 104, an LED 105, a CMOS camera 106, a pressure sensor 107, a processor 108 including a CPU, a memory 109 such as a ROM and a RAM, A communication unit 111 including a real-time clock 110, an antenna, and the like, and a battery 112 are provided.

  The tip of the ink cartridge 104 is a pen tip portion 103, and each writer taps the pen tip portion 103 of the electronic pen 1 on the answer sheet 5 or makes a stroke (handwriting while contacting the answer sheet 5). (Stroke). In this specification, the expression “entry” is also used for the tap with the electronic pen 1. The ink of the ink cartridge 104 does not include a material that absorbs infrared rays (for example, carbon). Here, the contact of the pen tip portion 103 of the electronic pen 1 with the answer sheet 5 is referred to as “pen down”, and the removal of the pen tip portion 103 from the contact (contact) state is “pen up”. Call it. A trajectory written between the pen-down and pen-up of the electronic pen 1 is one stroke, and characters, figures, etc. are composed of one or a plurality of strokes. Since the ink of the ink cartridge 104 does not include a material that absorbs infrared rays, the reading of the dot pattern by the processor 103 is not hindered.

  The battery 112 is for supplying electric power to each component in the electronic pen 1. For example, the battery 112 is configured to turn on / off the electronic pen 1 itself by attaching and detaching a cap (not shown) of the electronic pen 1. May be. The real time clock 110 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 108. The pressure sensor 107 measures the pressure applied through the ink cartridge 104 from the pen tip 103 when the writer writes characters or marks on the answer sheet 5 with the electronic pen 1 or taps on the answer sheet 5, that is, the writing pressure. The value is detected and the value is transmitted to the processor 108.

  The processor 108 switches on / off the switches of the LED 105 and the CMOS camera 106 based on the writing pressure data supplied from the pressure sensor 107. That is, when the writer enters a stroke or taps the answer sheet 5 with the electronic pen 1, the pen pressure is applied to the pen tip portion 103, and when the pressure sensor 107 detects a writing pressure higher than a predetermined value, The processor 108 determines that the writer has started filling in and activates the LED 105 and the CMOS camera 106. Then, the communication unit 111 associates pen-down information PD detected by the pressure sensor 107 with a pen ID described later, and transmits it as entry information to the aggregation device 2. Further, when the writer finishes entering one stroke and moves the electronic pen 1 away from the answer sheet 5, the pressure sensor 107 detects pen-up because no writing pressure exceeding a predetermined value is detected. Then, the communication unit 111 associates the pen-up information detected by the pressure sensor 107 with the pen ID and transmits it as entry information to the aggregation device 2.

  The LED 105 and the CMOS camera 106 are attached near the pen tip portion 103 of the electronic pen 1, and an opening 102 is formed in a portion of the housing 101 that faces the LED 105 and the CMOS camera 106. The LED 105 illuminates infrared rays toward the vicinity of the pen tip portion 103 on the answer sheet 5. The region is slightly shifted from the position where the pen tip portion 103 contacts the answer sheet 5. The CMOS camera 106 is provided with an infrared transmission filter that transmits infrared rays and blocks non-infrared rays. The CMOS camera 106 captures a dot pattern in an area illuminated by the LED 105, and the image data of the dot pattern is captured. This is supplied to the processor 108. Here, since carbon absorbs infrared rays, the infrared rays irradiated by the LED 105 are absorbed by the carbon contained in the dots. Therefore, the dot portion has a relatively small amount of infrared reflection, and the portion other than the dot has a relatively large amount of infrared reflection. By photographing with the CMOS camera 106, a threshold value is provided based on the difference in the amount of reflected infrared light, so that a dot region containing carbon can be distinguished from other regions. Therefore, even when an entry column or the like is printed on the answer sheet 5, the printed ink does not have an absorptivity in the infrared region, and thus the processor 108 can recognize the dot pattern. Note that the shooting area by the CMOS camera 106 is a range including a size of about 2 mm × about 2 mm as shown in FIG. 4A, and the shooting by the CMOS camera 106 is performed at regular intervals of about 50 to 100 times per second. Is called. Further, the CMOS camera 106 has a sufficient depth of field in order to photograph dots clearly.

  The processor 108 uses the dot pattern of the image data supplied by the CMOS camera 106 to perform X and Y coordinates (hereinafter simply referred to as “X” and “Y” coordinates) on the answer sheet 5 of the stroke (handwriting) to be entered by the entry person. "Position coordinates", "coordinate data", and "coordinate information") are calculated continuously. That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 4 (a) supplied by the CMOS camera 106 into the data array shown in FIG. 4 (b). The data is converted into a Y coordinate bit value, and X and Y coordinate data are calculated from the data array by a predetermined calculation method. The processor 108 has a rotation correction processing function for correcting the arrangement of dots on the image due to the angle of the electronic pen 1 facing the dot pattern, and is used for coordinate calculation. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, and X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. The 6 × 6 dot pattern in the answer sheet 5 does not overlap in the answer sheet 5, so when the writer enters characters or the like with the electronic pen 1, Whether it corresponds to the position can be specified by coordinate calculation by the processor 108.

  The memory 109 stores property information such as pen IDs “pen01” to “pen04”, pen manufacturer numbers, and pen software versions for identifying the electronic pens 1A to 1D. Then, the communication unit 111 associates the pen ID, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits them to the aggregation device 2 as entry information. Transmission to the aggregation device 2 by the communication unit 111 is performed instantaneously and sequentially by wireless transmission such as Bluetooth (registered trademark). Here, one or a plurality of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the aggregation device 2 is stored as stroke information by the aggregation device 2. In other words, one stroke is composed of one or a plurality of X and Y coordinates (coordinate points), and the aggregation device 2 uses one or more of the pen-down information and the pen-up information to constitute one or a plurality of strokes. Recognize coordinate attribute information.

  As described above, each time the writer enters the answer sheet 5, the electronic pens 1 </ b> A to 1 </ b> D generate entry information and transmit it to the aggregation device 2. In other words, the electronic pens 1 </ b> A to 1 </ b> D continue to generate entry information and transmit it to the aggregation device 2 while the entry person continues to fill in the answer sheet 5. Then, when the writer removes the electronic pen 1 from the answer sheet 5 (pens up), the electronic pen 1 does not detect a writing pressure exceeding a predetermined value by the pressure sensor 107, and the writer enters the information. Determined to have stopped. In this case, the pen-up electronic pen 1 stops the LED 105 and the CMOS camera 106 and stops sending the entry information to the aggregation device 2.

[Transfer device]
The transfer device 3 will be described with reference to FIG. FIG. 6 shows a system configuration diagram of the electronic pen system 10 including a functional block diagram of the transfer device 3 and a functional block diagram of the aggregation device 2.

  As shown in FIG. 6, the transfer device 3 includes a transfer reception unit 31 and a transfer transmission unit 32. The transfer receiving means 31 is means for receiving data such as entry information transmitted from the electronic pen 1 by the Bluetooth (registered trademark) wireless communication system. The transfer transmitting unit 32 is a unit that transmits data such as entry information received by the transfer receiving unit 31 to the aggregation device 2. The transmission of data to the aggregation device 2 by the transfer transmission means 32 may be performed by a TCP / IP communication system via a LAN, for example.

The transmission means 27 is a means for transmitting the display signal to the display means 26 to the projector 4 in synchronism with the projector 4 so that the same contents as the contents displayed on the display means 26 are displayed on the projector 4.

  The storage means 25 is constituted by a memory such as a ROM, a RAM, and a hard disk, and stores each user area and the position coordinates in the answer sheet 5 in association with each other. That is, as illustrated in FIG. 7A, the storage unit 25 stores user area definition information in which an area type and a position coordinate range are associated with each other for the user areas 501 and 502. The range of the user area is defined by the range from the coordinates (xn, yn) on the answer sheet 5 to the height (Y) direction Hn and the lateral (X) direction Wn, such as “(xn, yn), Hn, Wn”. Is done. Specifically, the range of the user area 501 is “(x1, y1), H1, W1”, the area type is stored as “answer column”, and the range of the user area 502 is “(X2, y2), H2, W2”, and the area type is stored as a “registration column”.

  Further, as shown in FIG. 7B, the storage unit 25 stores the user ID and the user name in association with each other as user definition information. For example, the storage unit 25 stores the user ID “U01” and the user name “Taro” in association with each other.

  Further, when the aggregation processing unit 24 (to be described later) associates the writer ID with the pen ID of the electronic pen 1 based on the entry information transmitted by each electronic pen 1, the storage unit 25 stores the pen ID and the entrant ID. Is stored as pen setting information as shown in FIG. Further, when the aggregation processing unit 24 associates the writer ID for each piece of entry information received from each electronic pen 1, the storage unit 25 identifies and stores the entry information for each writer ID. In addition, each figure of FIG. 8 is mentioned later.

  The storage unit 25 stores the learning data in a file format by executing the drawing application (program) by the aggregation processing unit 24. FIG. 9 shows a schematic structure of a data file format. As shown in FIG. 9, the learning data includes file attribute information and personal learning data for each writer ID. The file attribute information includes creation date information. In addition, the personal learning data is set by the user for categorization according to the writer ID, user stroke information including the position coordinate information of the entry information transmitted from the electronic pen 1, and the content of the answer. User color (classification) information, keyword information, and the like are included. The user stroke information includes position coordinate (XY coordinate) information calculated by the electronic pen 1, time information when written, and writing pressure information. When reading the file data, the input means 21 inputs the writer ID, the user color information, the keyword information, and the like, the aggregation processing means 24 searches for specific data, and the user stroke information is reproduced on the display means 26. Can be made.

  The aggregation processing unit 24 is a unit that aggregates and processes data from the electronic pen 1 and is configured by a processor such as a CPU that exhibits a function by executing an application program. When the aggregation processing unit 24 specifies the user ID to be associated with the pen ID and receives the entry information generated by filling in the user area 502 of the answer sheet 5 by the electronic pen 1 after the identification, the aggregation processing unit 24 includes the entry information. The included pen ID is associated with the identified user ID. Specifically, first, the aggregation processing unit 24 displays a pen setting button for associating the pen ID and the user ID on the screen by the drawing application, and associates the pen ID with the pen ID when the pen setting button is selected. A pen setting target user list in which user names corresponding to each of a plurality of target user IDs are displayed is displayed (see FIG. 10). Next, when one user name is selected from a plurality of user names shown in the pen setting target user list, the aggregation processing unit 24 specifies a user ID corresponding to the user name and uses the drawing application. A message prompting the user to tap the user area 502 (registration field) of the answer sheet 5 with the electronic pen 1 associated with the user ID (hereinafter referred to as “pen setting message” as appropriate) is displayed on the screen (see FIG. 11). ).

  Next, when the aggregation processing unit 24 receives the entry information including the position coordinates, the pen ID, and the like from the electronic pen 1, the user area and the range of the position coordinates in the user area definition information shown in FIG. , The user area 502 (registration field) on the answer sheet 5 is identified as the entry information tapped with the electronic pen 1, and the pen ID included in the entry information is as described above. Is associated with the specified user ID and stored in the storage means 25 as pen setting information shown in FIG. In this case, the aggregation processing unit 24 uses only the pen ID included in the entry information received within a predetermined time after displaying the pen setting message (may be after specifying the user ID) for association with the user ID. . When such association ends, the aggregation processing unit 24 displays a message indicating that the association between the pen ID and the user ID has ended (hereinafter referred to as “association end message” as appropriate) (see FIG. 12).

  Note that an option such as “all users” is also prepared in the pen setting target user list. When “all users” is selected, the aggregation processing unit 24 associates the pen ID with the user ID as described above. By performing the processing in order for each of the plurality of user IDs that are targets to be associated with the pen ID, all of the plurality of user IDs are associated with the pen ID.

  When the aggregation processing unit 24 receives the entry information including the position coordinates, the pen ID, and the like from the electronic pen 1 after associating the pen ID and the user ID as described above, the aggregation processing unit 24 illustrated in FIG. With reference to the relationship between the user area and the range of position coordinates in the user area definition information, if the user area 501 (answer column) on the answer sheet 5 is identified as the entry information that has been tapped or entered with the electronic pen 1, With reference to the pen setting information stored in the storage means 25, the writer ID associated with the pen ID included in the entry information is specified, and associated with the stroke information for the user area 501 of the answer sheet 5, The information is stored in the user stroke information storage area for each writer ID in the storage means 25. Therefore, since the writer ID is set in the aggregation device 2 via the pen ID in the position coordinates for the user area 501 of the answer sheet 5, a plurality of writers use the same electronic pen 1 (FIG. 8). (See (b)), even when the same writer uses different electronic pens 1 (see FIG. 8 (c)) Can be stored in the storage means 25 and recognized.

  In addition, when the aggregation processing means 24 receives the entry information about the user area 501 of the answer sheet 5 and the pen ID included in the entry information is not associated with the user ID, the aggregation ID is used as the entry ID. Are stored in the storage means 25, and the stroke information for the user area 501 of the answer sheet 5 is stored in the user stroke information storage area in the storage means 25 in association with the pen ID as the writer ID. Then, when the user ID is specified and associated with the pen ID later, the aggregation processing unit 24 refers to the learning data file in the storage unit 25 and receives the writer ID received before the association. The stroke information about the user area 501 of the answer sheet 5 associated with the same pen ID is newly associated with the specified user ID as the writer ID and stored in the user stroke information storage area in the storage unit 25. Therefore, even if the entry is started in the user area 501 of the answer sheet 5 before associating the pen ID with the user ID, if the pen ID and the user ID are associated with each other later, the aggregation device 2 performs processing means. 24, the identified user ID can be stored in the storage unit 25 retrospectively in association with the position coordinates of the user area 501, and the position acquired by the aggregation device 2 after being entered in the user area 501 after that. The coordinates can also be stored in the storage means 25 in association with the same writer ID.

  Further, the aggregation processing means 24 displays the entry contents on the display means 26 based on the learning data including the stroke information for the user area 501 of the answer sheet 5 and corresponds to the user ID associated with the writer ID. Display the user name. Since the entry contents by the electronic pen 1 and the user name corresponding to the user ID are displayed on the display means 26, the operation article of the aggregation device 2 can recognize both the entry person and the entry contents by the person. it can. Further, the aggregation processing unit 24 causes the transmission unit 27 to transmit the same signal as the display signal to the display unit 26 to the projector 4 in order to synchronize and display the same contents as the display unit 26.

  Hereinafter, specific functions of the aggregation processing unit 24 will be described in detail.

[Screen display by drawing application]
Next, with reference to FIGS. 10 to 13, a specific window based on the drawing application (also referred to as “drawing application window”) displayed on the display screen of the display means 26 will be described. Here, an example of a screen displayed when the association between the pen ID and the user ID is performed is mainly shown.

  FIG. 10 shows a pen setting target user list 202 displayed when the pen setting button 201 is selected in the drawing application window. First, before describing the pen setting button 201 and the pen setting target user list 202, the basic configuration of the drawing application window will be described.

  Based on the entry information generated when the electronic pen 1 fills in the user area 501 of the answer sheet 5, the user stroke information stored as individual learning data in the storage unit 25 by the aggregation device 2 is stored by the aggregation processing unit 24. The image is drawn in the user stroke information display area 50 of the display means 26. When the user stroke information to be drawn is larger than the user stroke information display area 50 in enlarged display or the like, the aggregation processing unit 24 enables the horizontal scroll bar 51 and the vertical scroll bar 52 so that the entire user stroke information can be displayed. To do.

  In FIG. 10, for convenience of explanation, a screen in which only the image of the answer sheet 5 on which the stroke information is not drawn is displayed in the user stroke information display area 50 is illustrated. Further, although the registration field (user area 502) is not displayed in the image of the answer sheet 5, the registration field (user area 502) may be displayed. The content described in this paragraph applies to FIGS. 11 to 13 as well.

  In addition, the aggregation processing unit 24 has, as function buttons, a selection user display button 53, a comparison list display button 54, a reproduction display button 56, a selection image output button 57, a display size change list 58, a reduction display button 59, An enlarged display button 61, page feed functions 62 and 63, rotation display buttons 64 and 66, a user control display button 67, a pen setting button 201, and the like are displayed, and each process is performed by selecting a function button with the mouse of the input means 21. Run.

  The selected user display button 53 is a button for displaying user stroke information corresponding to one user name selected from a user selection list 69 described later. The comparison list display button 54 is a button for displaying a list of user stroke information corresponding to a plurality of user names at the same time. The reproduction display button 56 is a button for reproducing and displaying user stroke information one stroke at a time. The selected image output button 57 is a button for outputting user stroke information within an arbitrary selection range as image data. By providing this function, it is possible to easily create a model answer collection that can be used as a reference from the information entered by each student.

  The display size change list 58 is a list indicating the display size of the user stroke information currently drawn in the user stroke information display area 50. The user can arbitrarily select and change the display size from the pull-down menu using the mouse. The reduction display button 59 is a function for reducing the display size of the user stroke information drawn in the user stroke information display area 50. The enlargement display button 61 is a function for enlarging the display size of the user stroke information drawn in the user stroke information display area 50. The page feed functions 62 and 63 are buttons for displaying the answer sheet 5 having different page addresses (paper dot patterns). The rotation display buttons 64 and 66 are buttons for rotating the user stroke information drawn in the user stroke information display area 50 by 90 degrees. By providing such a function, the paper orientation on the display can be easily changed. The user control display button 67 is a function for switching display / non-display of the user control list 68. By making it non-displayed, the user stroke information display area 50 can be enlarged.

  In addition, file data storage, application settings, and the like may be prepared as function menus in the same manner as general applications. As a pull-down menu for the file menu 84, a list of execution functions related to general management of the application such as a menu for reading and saving file data, a menu for saving in image format, and a menu for closing the application is prepared. It is convenient to keep it.

  In addition, since the file format for saving file data has a structure in which user stroke information for each user is associated with setting information, when reading the file data, user ID (entry ID), user color information, keyword information, etc. It is possible to search for specific data and display the searched user stroke information in the user stroke information display area 50.

  As a pull-down menu of the display menu 91, it is convenient to prepare a list of execution functions related to application display, such as a full-screen display menu that hides the window frame and maximizes the display area of the application. Further, as a pull-down menu of the tool menu 92, a pen management menu for displaying the connection status of the electronic pen 1 (for example, the IP address of the transfer device 3) and an image of the answer sheet 5 as a background for displaying user stroke information It is convenient to prepare a list of execution functions related to application settings such as a paper management menu to be set and a menu for displaying application information. When these buttons and menus are selected, each function is executed by the aggregation processing means 24.

  Here, when the operator of the aggregation device 2 selects the pen setting button 201, the aggregation processing unit 24 displays the pen setting target user list 202. The pen setting target user list 202 shows user names (Taro, Jiro,...) Corresponding to a plurality of user IDs to be associated with the pen ID, and selects a user name to be associated with the pen ID. It can be done. The user name shown in the pen setting target user list 202 corresponds to the user name stored in the storage unit 25 as user definition information (see FIG. 7B). The pen setting target user list 202 also displays an option such as “all users” for associating all of the plurality of user IDs with the pen ID.

  When the operator selects a desired user name from the pen setting target user list 202 with the mouse of the input unit 21, the aggregation processing unit 24 specifies a user ID corresponding to the selected user name. On the other hand, when the operator selects “all users” from the pen setting target user list 202 with the mouse of the input unit 21, the aggregation processing unit 24 specifies an arbitrary user ID from among a plurality of user IDs. When “all users” is selected, the aggregation processing unit 24 finishes associating the identified user IDs with the pen IDs, and selects a plurality of user IDs that have not been associated with the pen IDs so far. The user ID is identified from among the user IDs, and the process of associating the identified user ID with the pen ID is repeated. In this way, the aggregation processing unit 24 associates all of the plurality of user IDs with the pen ID.

  FIG. 11 shows a message box 203 that is displayed in the drawing application window after a user name is selected in the pen setting target user list 202 (that is, after a user ID corresponding to the user name is specified). Yes. Here, a case where “Taro” is selected as the user name (that is, a case where the user ID “U01” is specified) is taken as an example. In this case, the aggregation processing unit 24 selects “Taro (U01) to prompt the user to tap the registration field (user area 502) of the answer sheet 5 with the electronic pen 1 associated with“ U01 ”which is the user ID of“ Taro ”. Display a message box 203 showing a pen setting message such as “tap the pen to be associated with” in the registration field. Thereafter, when receiving the entry information about the user area 502 of the answer sheet 5 from the electronic pen 1, the aggregation processing unit 24 associates the pen ID included in the entry information with the user ID “U01”.

  FIG. 12 shows a message box 204 displayed when the association between the pen ID and the user ID is completed in the drawing application window. Here, a case where the pen ID “pen01” is associated with the user ID “U01” of the user name “Taro” is taken as an example. In this case, the aggregation processing unit 24 displays a message box 204 in which an association end message such as “The association between the pen 1A (pen01) and Taro (U01) has ended” is displayed.

  FIG. 13 shows an example of a drawing application window that is displayed after the association with the pen ID is completed for all of the plurality of user IDs.

  As shown in FIG. 13, the aggregation processing unit 24 displays a user selection list 69 in the user control list 68. The user selection list 69 is a list for selecting user stroke information displayed in the user stroke information display area 50 by a user name. The aggregation processing unit 24 includes a user name corresponding to the writer ID (user ID) associated with each user stroke information acquired from the electronic pen 1 and stored in the storage unit 25 as individual learning data, and a color classification button 71. Information of each user such as user color (classification) information and keywords selected by ˜76 is displayed in the user selection list 69. In the user name column of the user selection list 69, the user name corresponding to the writer ID of the individual learning data stored in the storage unit 25 is displayed by the aggregation processing unit 24. That is, the user name corresponding to the user ID set as the writer ID is displayed by the association between the pen ID and the user ID as described above (note that the pen ID is set as the writer ID). In this case, a pen ID is displayed).

  When the operator selects a desired user from the user selection list 69 with the mouse of the input means 21 and clicks the selected user display button 53, the aggregation processing means 24 displays the stroke information of the selected user on the answer sheet 5. Along with the image, it is displayed in the user stroke information display area 50. In FIG. 13, the user name “Saburo” is selected from the user selection list 69, and the electronic pen 1 having a pen ID associated with the user ID “U03” of the user name “Saburo” is displayed in the user stroke information display area 50. The entry content entered in is displayed together with the image of the answer sheet 5. Further, it is possible to directly input characters into the keyword column of the user selection list 69 using the keyboard of the input unit 21, and the aggregation processing unit 24 stores the input characters as keyword information of the personal learning data file. 25 (see FIG. 9).

  In addition to the user selection list 69, the user control list 68 displays color classification buttons 71 to 76, a list order sort button 78, a color order sort button 79, a classification graph display button 81, a reload button 82, and the like.

  The color classification buttons 71 to 76 are buttons for setting user color (classification) information for each user displayed in the user selection list 69. The button 71 is a button for setting red, the button 72 for blue, the button 73 for yellow, the button 74 for green, the button 75 for brown, and the button 76 for white. When the operator of the aggregation device 2 selects a specific user name in the user selection list 69 with the mouse of the input unit 21 and selects a desired button among the color classification buttons 71 to 76, the aggregation processing unit 24 A column for displaying the color classification of the selected user name in the user selection list 69 is displayed in the designated color. With this function, the operator instructor can see the answer contents of the writer (students) displayed in the user stroke information display area 50, categorize the way of thinking, etc., and make the colors easier to see. it can. The user color (classification) information may be set to white when not set.

  The list order sort button 78 is a button for rearranging the user list displayed in the user selection list 69 in order of user ID (name list order). The color order sort button 79 is used to display the user list displayed in the user selection list 69 so that the users having the same color information attached by the operation of the color classification buttons 71 to 76 are arranged in succession. It is a button for rearranging in order of information. The classification graph display button 81 is a button for displaying the number of users for each user color information attached by operating the color classification buttons 71 to 76 in the user stroke information display area 50 as a bar graph or the like.

  The reload button 82 is a button for returning the user stroke information of the user selected in the user selection list 69 to the state when the learning data file is saved. With this function, when the instructor who is the operator selects the reload button 82 with the mouse, the aggregation processing unit 24 performs electronic processing after the previous file storage based on the writer ID associated with the selected user. The user stroke information received from the pen 1 and stored in the storage area for each writer ID in the storage means 25 is cleared, the user stroke information up to the time when the file was saved last time is read and displayed in the user stroke information display area 50. . This function can be used when an individual user wants to redo an answer.

[Processing flow]
Next, a processing flow performed in the present embodiment will be described with reference to FIGS.

  FIG. 14 is a processing flow showing a function for setting a writer ID in entry information transmitted by each electronic pen 1. This processing flow is performed when a user name is selected in the pen setting target user list 202 (that is, when “all users” is not selected).

  First, in the aggregation device 2, the aggregation processing unit 24 determines whether or not the pressing of the pen setting button 201 is detected (step S201). When the aggregation processing unit 24 detects the pressing of the pen setting button 201 (step S201: Yes), the aggregation processing unit 24 displays the pen setting target user list 202 (step S202) (see FIG. 10). Then, the aggregation processing unit 24 specifies the user ID corresponding to the user name selected in the pen setting target user list 202 as the user ID to be associated with the pen ID (step S203), and specifies the message ID in the message box 203. The registration field of the answer sheet 5 (a pen setting message prompting the user area 502 to be tapped is displayed by the electronic pen 1 associated with the user ID (step S204) (see FIG. 11).

  Next, in response to the pen setting message, when the writer of the user name corresponding to the specified user ID fills in the answer sheet 5 with the electronic pen 1, the electronic pen 1 reads the dot pattern near the pen tip portion 103. The stroke information constituted by the calculated position information and the like and the entry information including the pen ID are transmitted to the aggregation device 2 (step S101). In the aggregation device 2, the entry information from the electronic pen 1 is received by the receiving means 22 and 23, and is processed by the aggregation processing means 24. In this case, the aggregation processing unit 24 stores the entry information including the stroke information and the pen ID in the storage unit 25 (step S205).

  Next, the aggregation processing unit 24 determines from the position coordinates included in the entry information whether or not an entry has been made in the registration field by the electronic pen 1 (step S206). Specifically, the aggregation processing unit 24 refers to the relationship between the user area and the range of the position coordinates in the user area definition information (refer to FIG. 7A) in the storage unit 25, and the answer sheet 5 by the electronic pen 1. It is determined whether or not an entry has been made in the upper registration field (user area 502).

  If it is determined that the entry is entered in the registration field (step S206: Yes), the aggregation processing unit 24 has received the entry information within a predetermined time after the pen setting message is displayed in step S204. It is determined whether or not (step S207). When the aggregation processing unit 24 determines that the entry information has been received within the predetermined time (step S207: Yes), the aggregation processing unit 24 performs a pen ID and user ID association process described later (step S208), and sets the pen setting button 201 for pen setting. The function is turned off and the process is terminated. On the other hand, if the aggregation processing unit 24 determines that the entry information has not been received within the predetermined time (step S207: No), the pen setting button is not performed without performing the association process between the pen ID and the user ID. The pen setting function 201 is turned off, and the process ends. This is because, when entry information is received after a long time has elapsed since the pen setting message was displayed, the entry on the answer sheet 5 by the electronic pen 1 corresponding to the entry information is This is because there is a high possibility that it is not performed to associate the ID with the user ID. Needless to say, when the entry information is not received in the first place, the association process between the pen ID and the user ID is not performed.

  On the other hand, when it is determined that the registration field is not filled (step S206: No), the aggregation processing unit 24 does not perform the process for associating the pen ID and the user ID as described above, and the pen setting button 201. Turn off the pen setting function. In this case, it is because the electronic pen 1 filled in not the registration field (user area 502) but the answer field (user area 501). Specifically, when the aggregation processing unit 24 determines that the entry is not entered in the registration field (step S206: No), the electronic pen included in the entry information is first referred to the pen setting information in the storage unit 25. It is determined whether or not a writer ID is set for one pen ID (step S210). If the aggregation processing unit 24 determines that the entry ID is not set for the pen ID of the electronic pen 1 (step S210: No), the aggregation processing unit 24 sets the pen ID of the electronic pen 1 as the entry ID and stores it in the storage unit 25. When it is determined that the writer ID is set for the pen ID of the electronic pen 1 (step S210: Yes), the writer ID already set in the pen ID of the electronic pen 1 is maintained. The entry ID is not changed by the pen ID of the electronic pen 1. Thereafter, the aggregation processing unit 24 draws a stroke based on the stroke information stored in step S205 (step S212). In this case, when the user ID is already associated with the pen ID stored in step S205, the aggregation processing unit 24 may draw a stroke in the user stroke information display area 50 corresponding to the user ID.

  On the other hand, when the pressing of the pen setting button 201 is not detected (step S201: No), the above-described processing of steps S202 to S208 is not performed. That is, the process for associating the pen ID with the user ID is not performed. In this case, in the aggregation device 2, when the entry information from the electronic pen 1 is received by the receiving means 22 and 23, the aggregation processing means 24 stores the entry information including the stroke information and the pen ID in the storage means 25 (step S209). : Reference figure 9). Then, the aggregation processing unit 24 refers to the pen setting information in the storage unit 25 and determines whether or not the writer ID is set for the pen ID of the electronic pen 1 included in the entry information (step S210). If the aggregation processing unit 24 determines that the entry ID is not set for the pen ID of the electronic pen 1 (step S210: No), the aggregation processing unit 24 sets the pen ID of the electronic pen 1 as the entry ID and stores it in the storage unit 25. When it is determined that the writer ID is set for the pen ID of the electronic pen 1 (step S210: Yes), the writer ID already set in the pen ID of the electronic pen 1 is maintained. The entry ID is not changed by the pen ID of the electronic pen 1. Thereafter, the aggregation processing unit 24 draws a stroke based on the stroke information stored in step S209 (step S212). In this case, when the user ID is already associated with the pen ID stored in step S209, the aggregation processing unit 24 may draw a stroke in the user stroke information display area 50 corresponding to the user ID. . If the stroke information stored in step S209 is generated by filling in the registration field (user area 502) of the answer sheet 5, the stroke drawing process (step S212) is not performed. Needless to say. In addition, in this case, the process of setting the pen ID as the writer ID (step S211) may not be performed.

  FIG. 15 is a flowchart showing the association process between the pen ID and the user ID performed in step S208 of FIG. This processing flow is also performed in step S508 of FIG.

  First, the aggregation processing unit 24 refers to the pen setting information (refer to FIG. 8A) in the storage unit 25, and sets the writer ID corresponding to the pen ID of the electronic pen 1 included in the entry information. It is determined whether or not (step S301). When the aggregation processing unit 24 determines that the writer ID is not set corresponding to the pen ID of the electronic pen 1 (step S301: No), the writer ID is specified in step S203 of FIG. A user ID is set and stored in the storage means 25 (step S304). Then, the aggregation processing unit 24 displays an association end message indicating that the association between the pen ID and the user ID has ended (step S305) (see FIG. 12).

  On the other hand, in step S301, when the aggregation processing unit 24 determines that the writer ID is set corresponding to the pen ID of the electronic pen 1 (step S301: Yes), the pen ID is used as the writer ID. Is determined (step S302). At this time, when the aggregation processing unit 24 determines that the pen ID is not set as the writer ID (step S302: No), the ID set as the writer ID is identified in step S203 of FIG. It is determined whether or not it is a user ID (step S303). When the user ID is different from the user ID specified in step S203 (step S303: Yes), the writer ID of the pen ID of the electronic pen 1 is set as the user ID specified in step S203. (Step S304) (refer to FIG. 8B, pen ID = pen01). Then, the aggregation processing unit 24 displays an association end message indicating that the association between the pen ID and the user ID has ended (step S305) (see FIG. 12). On the other hand, when it is the same as the user ID specified in step S203 in FIG. 14 (step S303: No), the aggregation processing unit 24 displays an association end message indicating that the association between the pen ID and the user ID has ended (step S303). S305) (Refer to FIG. 12). In this case, the writer ID already set in the pen ID of the electronic pen 1 is maintained as it is.

  On the other hand, in step S302, when the aggregation processing unit 24 determines that the pen ID is set as the writer ID (step S302: Yes), it refers to the learning data file stored in the storage unit 25, and The writer ID of the personal learning data stored with the pen ID as the writer ID is retroactively changed to the user ID specified in step S203 of FIG. 14 and stored in the storage means 25 (step S306). The writer ID of the pen setting information related to the electronic pen 1 in the storage unit 25 is changed from the pen ID to the user ID specified in step S203 and stored (step S307) (see FIG. 8B, pen ID = pen02). ). Then, the aggregation processing unit 24 displays an association end message indicating that the association between the pen ID and the user ID has ended (step S305) (see FIG. 12).

  FIG. 16 is another example of the processing flow showing the function of setting the writer ID for the entry information transmitted by each electronic pen 1. This processing flow is performed instead of the processing flow shown in FIG. 14 when “all users” is selected in the pen setting target user list 202.

  In the aggregation device 2, the aggregation processing unit 24 determines whether or not the pressing of the pen setting button 201 is detected (step S501). When the aggregation processing unit 24 detects that the pen setting button 201 is pressed (step S501: Yes), the aggregation processing unit 24 displays the pen setting target user list 202 (step S502) (see FIG. 10). The steps so far are the same as steps S201 and S202 in FIG. When the aggregation processing unit 24 detects that “all users” has been selected in the pen setting target user list 202, the processing unit 24 has previously selected a plurality of user IDs (U01 to U05). An electronic pen 1 that is a user ID that has not been associated with the pen ID and the user ID and that has the smallest user ID number (step S503) and is associated with the identified user ID in the message box 203 Displays a pen setting message prompting the user to tap in the registration field of the answer sheet 5 (step S504) (see FIG. 11). Here, since the user ID is specified first, the processing unit 24 specifies the user ID “U01” as the target of association.

  Steps S401 and S505 to 512 in FIG. 16 are the same as steps S101 and S205 to 212 in FIG. Next, the processing after step S513 will be described. The process in step S513 is performed after the pen ID and user ID association process (step S508). In step S513, the aggregation processing unit 24 determines whether pen IDs are associated with all user IDs. When the pen IDs are associated with all user IDs (step S513: Yes), the pen setting function of the pen setting button 201 is turned off and the process is terminated. On the other hand, when the pen IDs are not associated with all user IDs (step S513: No), the process returns to step S503. In this case, the aggregation processing means 24 is a user ID that has not been associated with a pen ID and a user ID so far among a plurality of user IDs (U01 to U05) and has the smallest user ID number. An ID is specified (step S503), and processing for associating the pen ID with the specified user ID (steps S504 to S508) is performed. Then, the determination in step S513 is performed again. The aggregation processing unit 24 associates the pen IDs with all the user IDs in the order of the user ID numbers by repeatedly performing the processes in steps S503 to S513.

  It is not limited to associating one pen ID with one user ID, and a plurality of pen IDs may be associated with one user ID. That is, the same user ID may be associated with a plurality of pen IDs. In one example, when it is determined in step S207 of FIG. 14 and S507 of FIG. 16 that the entry information is received within a predetermined time, the entry information received within the predetermined time is received by the plurality of electronic pens 1. When it is transmitted, the plurality of pen IDs transmitted by the plurality of electronic pens 1 can be associated with the identified user ID. In another example, in step S207 of FIG. 14 and S507 of FIG. 16, instead of determining whether the entry information is received within a predetermined time, the entry information transmitted by the predetermined number of electronic pens 1 is received. A plurality of pen IDs transmitted by the predetermined number of electronic pens 1 and the specified user IDs when it is determined that the entry information transmitted by the predetermined number of electronic pens 1 has been received. Can be associated. As described above, a plurality of electronic pens 1 corresponding to a plurality of pen IDs can be grouped by associating the same user ID with a plurality of pen IDs.

  Hereinafter, the flow of the processing flow described above will be described by taking the following cases (1), (2), and (3) as examples. The grouping function will be described by taking the case of (4) as an example.

  (1) When filling in the user area 501 (answer field) of the answer sheet 5 after associating the pen ID with the user ID

  14, 15, and 17, the operator of the aggregation device 2 selects the writer “Taro” in the pen setting target user list 202, and then the writer “Taro” sends a pen setting message. A case will be described in which the user area 501A (answer field) of the answer sheet 5A is entered after the user area 502A (registration field) of the answer sheet 5A is tapped with the electronic pen 1A.

  In the aggregation device 2, the aggregation processing unit 24 displays the pen setting target user list 202 when detecting the pressing of the pen setting button 201 by the operator (step S201: Yes) (step S202). Then, when the operator selects the writer “Taro” in the pen setting target user list 202, the aggregation processing unit 24 selects the user ID “U01” corresponding to “Taro” selected in the pen setting target user list 202. Is specified (step S203), and a pen setting message is displayed in the message box 203 urging the user to tap the user area 502 (registration field) of the answer sheet 5 with the electronic pen 1 associated with the user ID “U01” (step S203). S204).

  When the user “Taro” taps the user area 502A of the answer sheet 5A with the electronic pen 1A, the electronic pen 1A enters the stroke information (position information, etc.) calculated at the time of tap and the entry information including the pen ID “pen01”. Is transmitted to the aggregation device 2 (step S101). The aggregation device 2 receives the entry information from the electronic pen 1 </ b> A by the aggregation individual reception unit 22 and causes the aggregation processing unit 24 to process it. The aggregation processing unit 24 stores entry information including the stroke information and the pen ID in the storage unit 25 (step S205). Then, the aggregation processing unit 24 determines from the position coordinates included in the entry information that the entry was made in the user area 502A by the electronic pen 1A (step S206: Yes), and that the entry information was received within a predetermined time. Judgment is made (step S207: Yes), and pen ID and user ID association processing is performed (step S208).

  In this case, since the writer ID is not yet set in the pen setting information of the electronic pen 1A in the storage unit 25 (step S301: No), the aggregation processing unit 24 sets the writer ID of the electronic pen 1A in step S203. Is set to the user ID “U01” specified in step S304 and stored in the storage unit 25 (step S304). Then, the aggregation processing unit 24 displays an association end message indicating that the association between the pen ID “pen01” of the electronic pen IA and the user ID “U01” of the writer “Taro” has ended (step S305).

  Subsequently, when the writer “Taro” writes an answer with the electronic pen 1A in the user area 501A (answer field) of the answer sheet 5A, the electronic pen 1A detects the stroke information and the pen ID “for the user area 501A of the answer sheet 5A”. Entry information including “pen01” is transmitted to the aggregation device 2. Then, in the aggregation device 2, the aggregation processing unit 24 stores the entry information including the stroke information and the pen ID in the storage unit 25, and the user ID “U01” is set as the writer ID in the electronic pen 1A. The writer ID “U01” is associated with the stroke information for the user area 501A of the answer sheet 5A and stored in the user stroke information storage area of the personal learning data file for each writer ID in the storage means 25. .

  (2) Subsequent to (1), another user ID is associated with the same pen ID and entered in the user area 501 (answer field) of the answer sheet 5

  14, 15, and 18, following the example of (1), the operator of the aggregation device 2 selects the writer “Saburo” in the pen setting target user list 202, and then fills in After the pen setting message is displayed, the writer “Saburo”, who is different from the user “Taro”, taps the user area 502C (registration field) of the answer sheet 5C with the same electronic pen 1A as the writer “Taro”. A case where an answer is entered in the user area 501C (answer field) of the sheet 5C will be described.

  In the aggregation device 2, the aggregation processing unit 24 displays the pen setting target user list 202 when detecting the pressing of the pen setting button 201 by the operator (step S201: Yes) (step S202). When the operator selects the entrant “Saburo” in the pen setting target user list 202, the aggregation processing unit 24 uses the user ID “U03” corresponding to “Saburo” selected in the pen setting target user list 202. Is specified (step S203), and a pen setting message is displayed in the message box 203 urging the user to tap the user area 502 (registration field) of the answer sheet 5 with the electronic pen 1 associated with the user ID “U03” (step S203). S204).

  Then, when the writer “Saburo” taps the user area 502C of the answer sheet 5C with the electronic pen 1A, the electronic pen 1A enters the entry information including the stroke information (position information, etc.) calculated at the time of tapping and the pen ID “pen01”. Is transmitted to the aggregation device 2 (step S101). The aggregation device 2 receives the entry information from the electronic pen 1 </ b> A by the aggregation individual reception unit 22 and causes the aggregation processing unit 24 to process it. The aggregation processing unit 24 stores entry information including the stroke information and the pen ID in the storage unit 25 (step S205). Then, the aggregation processing unit 24 determines from the position coordinates included in the entry information that the entry has been made in the user area 502C by the electronic pen 1A (step S206: Yes), and that the entry information has been received within a predetermined time. Judgment is made (step S207: Yes), and pen ID and user ID association processing is performed (step S208).

  In this case, since the user ID “U01” of “Taro” who previously used the electronic pen 1A is set in the entry ID of the electronic pen 1A, the aggregation processing unit 24 has the entry ID of It is recognized that it has already been set (step S301: Yes), and it is determined that the writer ID is not a pen ID (step S302: No). Furthermore, the aggregation processing unit 24 fills in the pen setting information of the electronic pen 1A because the user ID “U03” specified in step S203 is different from the set writer ID “U01” (step S303: Yes). The user ID is updated to the specified user ID “U03” and stored in the storage unit 25 (step S304). Then, the aggregation processing unit 24 displays an association end message indicating that the association between the pen ID “pen01” of the electronic pen IA and the user ID “U03” of the writer “Saburo” has ended (step S305).

  Subsequently, when the entrant “Saburo” writes an answer with the electronic pen 1A in the user area 501C (answer field) of the answer sheet 5C, the electronic pen 1A detects the stroke information and the pen ID “for the user area 501C of the answer sheet 5C”. Entry information including “pen01” is transmitted to the aggregation device 2. Then, in the aggregation device 2, the aggregation processing unit 24 stores the entry information including the stroke information and the pen ID in the storage unit 25, and the user ID “U03” is set as the writer ID in the electronic pen 1A. The writer ID “U03” is associated with the stroke information for the user area 501C of the answer sheet 5C and stored in the user stroke information storage area of the personal learning data file for each writer ID in the storage means 25. .

  (3) Since the pen ID and the user ID are not associated with each other, the answer is entered in the user area 501 (answer field) of the answer sheet 5 in advance, and the pen ID and the user ID are associated later. If you continue to fill in the user area 501 of the answer sheet 5

  Referring to FIGS. 14, 15, and 19, the writer “Jiro” enters the user area 501 </ b> B (answer field) of the answer sheet 5 </ b> B in advance from the state where the writer ID is not set in the aggregation device 2. After the answer is entered, the operator of the aggregation device 2 selects the entry person “Jiro” in the pen setting target user list 202, and the entry person “Jiro” displays the pen setting message, and then the electronic pen 1B. A case where the user area 502B (registration field) of the answer sheet 5B is tapped and the answer is written in the user area 501B of the answer sheet 5B will be described.

  In this case, in the aggregation device 2, the aggregation processing unit 24 does not detect pressing of the pen setting button 201 (step S201: No). Therefore, the aggregation processing unit 24 does not perform the process for associating the pen ID and the user ID (the processes in steps S202 to S208), and performs the processes after step S209.

  First, when the writer “Jiro” starts writing an answer with the electronic pen 1B in the user area 501B (answer field) of the answer sheet 5B, the electronic pen 1B detects stroke information (position information) about the user area 501B of the answer sheet 5B. ) And the pen ID “pen02” of the electronic pen 1B is transmitted to the aggregation device 2 (step S101). The aggregation device 2 receives the entry information from the electronic pen 1B by the aggregation individual receiving unit 22 and causes the aggregation processing unit 24 to process it. The aggregation processing unit 24 stores the entry information including the stroke information and the pen ID in the storage unit 25 (step S209). In this case, since the writer ID is not set in the pen setting information of the electronic pen 1B in the storage unit 25, the aggregation processing unit 24 stores the writer ID of the electronic pen 1B in the storage unit 25. It is recognized that it is not set (step S210: No), and the pen ID “pen02” of the electronic pen 1B is temporarily set as the writer ID and stored in the storage means 25 (step S211). Then, the aggregation processing means 24 associates the writer ID “pen02” with the stroke information for the user area 501B of the answer sheet 5B and stores it in the user stroke information storage area of the personal learning data file for each writer ID in the storage means 25. Let

  Thereafter, in the aggregation device 2, when the aggregation processing unit 24 detects that the operator presses the pen setting button 201 (step S201: Yes), it displays the pen setting target user list 202 (step S202). When the operator selects the writer “Jiro” in the pen setting target user list 202, the aggregation processing unit 24 selects the user ID “U02” corresponding to “Jiro” selected in the pen setting target user list 202. Is identified (step S203), and a pen setting message is displayed in the message box 203 urging the user to tap the user area 502 (registration field) of the answer sheet 5 with the electronic pen 1 associated with the user ID “U02” (step S203). S204).

  When the user “Jiro” taps the user area 502B of the answer sheet 5B with the electronic pen 1B, the electronic pen 1B enters the entry information including the stroke information (position information, etc.) calculated at the time of tapping and the pen ID “pen02”. Is transmitted to the aggregation device 2 (step S101). The aggregation device 2 receives the entry information from the electronic pen 1B by the aggregation individual receiving unit 22 and causes the aggregation processing unit 24 to process it. The aggregation processing unit 24 stores entry information including the stroke information and the pen ID in the storage unit 25 (step S205). Then, the aggregation processing means 24 determines from the position coordinates included in the entry information that the entry has been made in the user area 502B by the electronic pen 1B (step S206: Yes), and such entry information is received within a predetermined time. It is determined that the pen ID and the user ID are associated (step S208).

  In this case, in the storage unit 25, the writer ID of the electronic pen 1B is temporarily set to “pen02”. Therefore, the aggregation processing unit 24 recognizes that the writer ID is set (step S301: Yes), but recognizes that the writer ID that has been set is a pen ID ("pen02") (step S302). : Yes). Therefore, the aggregation processing unit 24 obtains the writer ID of the personal learning data stored as the writer ID “pen02” among the personal learning data acquired in advance and stored in the storage unit 25 for each writer ID. “Pen02” is retroactively changed to the specified user ID “U02” and stored in the storage unit 25 (step S306), and the writer ID of the electronic pen 1B in the storage unit 25 is changed from “pen02” to the user ID “ "U02" and stored (step S307). Then, the aggregation processing unit 24 displays an association end message indicating that the association between the pen ID “pen02” of the electronic pen IB and the user ID “U02” of the writer “Jiro” has ended (step S305).

  Subsequently, the entrant “Jiro” returns to the user area 501B (answer field) of the answer sheet 5B and starts to write the answer again with the electronic pen 1B. The electronic pen 1B then moves to the user area 501B of the answer sheet 5B. The entry information including the stroke information and the pen ID “pen02” is transmitted to the aggregation device 2. Then, in the aggregation device 2, the aggregation processing unit 24 stores the entry information including the stroke information and the pen ID in the storage unit 25, and recognizes that the writer ID “U02” is set in the electronic pen 1B. Thus, the writer ID “U02” is associated with the stroke information for the user area 501B of the answer sheet 5B and stored in the user stroke information storage area of the personal learning data file for each writer ID in the storage means 25.

  As described above, according to the writer ID setting function of the aggregation processing unit 24, if the pen ID and the user ID are associated in advance, the user ID is associated with the stroke information for the user area 501 of the answer sheet 5. Although it is stored in the storage unit 25, even if the answer is entered in the user area 501 of the answer sheet 5 in a state where the pen ID and the user ID are not associated with each other, the pen ID and the user are subsequently entered. If the ID is associated, the user stroke information of the contents previously entered in the user area 501 of the answer sheet 5 is also retroactively associated with the user ID, and subsequently the contents of the contents entered in the user area 501 of the answer sheet 5 The user ID is also associated with the user stroke information.

(4) Grouping function The grouping function of the writer ID setting function will be described with reference to FIG. As shown in FIG. 20, the operator of the aggregation device 2 selects the writer “Jiro” in the pen setting target user list 202, and the three writers are each unique within a predetermined time after the pen setting message is displayed. The user areas 502A to 502C (registration fields) of the answer sheets 5A to 5C are tapped with different electronic pens 1A to 1C having different pen IDs. Then, in the aggregation device 2, the aggregation processing unit 24 sets the user ID “U02” as the writer ID for the electronic pens 1 </ b> A to 1 </ b> C. In this case, each entrant who uses the electronic pens 1A to 1C belongs to the group having the user name “Jiro” corresponding to the user ID “U02” as the group head, and the user ID in the aggregation device 2 Can be grouped by. Of course, when this grouping function is used, the group name may be stored in the storage unit 25 of the aggregation device 2 and the group name may be set.

[Effects of this embodiment]
According to the present embodiment described above, it is possible to appropriately associate the pen ID of the electronic pen 1 with the user ID. Specifically, according to the present embodiment, after displaying the pen setting message, the pen ID and user ID of the electronic pen 1 are triggered by the tap of the answer sheet 5 by the electronic pen 1 to the user area 502 (registration field). Can be properly associated with the. Furthermore, according to the present embodiment, if the writer has tapped the user area 502 (registration field) of the answer sheet 5 with the electronic pen 1, the linking device 2 associates the pen ID with the user ID. Even in the middle of performing, entry into the user area 501 (answer field) of the answer sheet 5 can be performed.

  Moreover, according to this embodiment, since it is not necessary to use a writer setting sheet as described in Patent Document 3, it is possible to easily associate a pen ID with a user ID. Here, in the technique described in Patent Document 3, for example, one writer setting sheet is turned to a plurality of writers, and each writer sets the writer with the electronic pen 1 when the writer setting sheet is turned. Since tapping was performed on the paper, it took a long time to associate a plurality of pen IDs with a plurality of user IDs. On the other hand, according to the present embodiment, the operator side sequentially selects the writers to be associated with the pen ID, and the filler side selects the user area of the answer sheet 5 with the electronic pen 1. Since it is sufficient to sequentially tap 502 (registration column), the time required for associating a plurality of pen IDs with a plurality of user IDs can be shortened as compared with the technique described in Patent Document 3.

  Such an embodiment can be suitably used for attendance confirmation in a lecture. Specifically, the operator (instructor) side operates the aggregating device 2 to select one by one, and the entrant (student) side selects the user by referring to the screen projected on the screen 6. When the user is selected, the electronic pen 1 taps on the user area 502 (registration field) of the answer sheet 5 with the electronic pen 1, so that the operator can input the electronic information in which the entry information is transmitted when the writer is selected. The entry person of the pen 1 can be treated as attendance, and the entry person of the electronic pen 1 whose entry information has not been transmitted when the entry person is selected can be treated as absent.

  In addition, according to the present embodiment, even if the user begins to fill in the user area 501 (answer field) of the answer sheet 5 prior to the association between the pen ID and the user ID, the pen ID and the user ID are subsequently changed. If the association is performed, the user ID can be set retrospectively. Further, according to the present embodiment, even when a single electronic pen 1 is used by a plurality of writers or the like, the user can be identified by associating a plurality of user IDs with the pen ID of the electronic pen 1. can do. Further, according to the present embodiment, even when the system 10 is used with a plurality of electronic pens 1 in a group composed of a plurality of persons, the electronic pens 1 used by each of the members of the same group are used. If the same user ID is associated with the pen ID, entry information from the electronic pens 1 belonging to the same group can be grouped and aggregated in the aggregation device 2. Moreover, according to this embodiment, even when the electronic pen 1 breaks down and another electronic pen 1 is required, or when one writer uses a plurality of electronic pens 1, By associating the same user ID with the pen ID, it is possible to collect the entry information as information of the same entry person.

[Modification]
In the above embodiment, when the aggregation device 2 receives the entry information within a predetermined time (Yes) in steps S207 and S507 (Yes), the association processing between the pen ID and the user ID is performed. It is also possible to make it a condition that entry information is received from a predetermined number of electronic pens. For example, when the pen ID and the user ID are associated with each other on a one-to-one basis, the processing unit 24 of the aggregation device 2 receives the entry information from one electronic pen 1 in steps S207 and S507. When the pen IDs are to be associated with each other and are grouped, the processing unit 24 of the aggregation device 2 receives the entry information from the predetermined plurality of electronic pens 1 in steps S207 and S507. The pen ID of the electronic pen 1 may be associated with the same user ID.

  In the above embodiment, the Anoto method is used for the electronic pen, the dot pattern (coded pattern), and the entry information, but the use of the Anoto method is not limited.
