Description

  The present invention relates to an electronic pen system using an electronic pen that calculates the position coordinates of a pen tip portion on a sheet, and an electronic pen system that displays on a terminal device the contents of entry entered on a plurality of sheets, and the same Regarding the program.

  Conventionally, electronic pens that digitize written information have been developed, and “Anot Pen” developed by Swedish company Anoto is known as a representative one. Anotopen is used together with dedicated paper (hereinafter also referred to as “dedicated paper”) on which a predetermined dot pattern is printed. In addition to the usual ink cartridge for writing characters, etc., the anotopen has a small camera for capturing the dot pattern printed on the dedicated paper and the position coordinates on the dedicated paper from the captured dot pattern. A processor for calculating and a data communication unit for transmitting the calculated position coordinates and the like to an external device are mounted. When a user writes characters, etc. on the special paper with an annotated pen, or puts a check mark on the image designed on the special paper, the small camera prints a dot pattern printed on the special paper as the pen moves. Information such as characters and images written by the user is recognized from continuous position coordinates obtained by imaging and calculated by the processor. Then, this entry information is transmitted by the data communication unit from the Anotopen to a terminal device such as a nearby personal computer or mobile phone (for example, see Patent Document 1).

  The present applicant has proposed a learning scoring system that efficiently counts the results of scoring such as a mock test using such an electronic pen (Patent Document 2). There has also been proposed a system that stores learning data shared by a plurality of students in a storage device and provides learning data while counting accesses from the terminals of the students (Patent Document 3). In addition, a system has been proposed in which a student enters an answer on a question sheet with an electronic pen, and a file is created by storing the contents written on each electronic pen for each question sheet (patent) Reference 4). Moreover, in the scoring system, in order to improve scoring efficiency, a system that cuts out the same answer column of each answer sheet filled in by a plurality of writers and displays a list on a display screen has been proposed (Patent Document 5).

<First Embodiment>
[System configuration of electronic pen system]
FIG. 1 is a system configuration diagram of an electronic pen system 10 according to the first embodiment. As shown in FIG. 1, the electronic pen system 10 has an answer sheet (entry sheet) 5A, 5B,... (5) distributed to each student (user) and an answer sheet (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 to 1 </ b> C. However, since there are many answer sheets 5 to be filled in, the number of electronic pens 1 that transmit the entry information is large. If the location where the student answers is out of the range of the wireless communication due to the remote location, etc., the entry information transmitted from the other electronic pens 1D, 1E,. A transfer device 3 for transferring 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 a screen.

[Answer sheet]
The answer sheet (entry form) 5 will be described with reference to FIG. Each answer sheet 5 has a dot pattern (coded pattern) of the same pattern printed on substantially the entire surface thereof, and a user area 501 is defined thereon. Further, each answer sheet 5 is printed with an entry field for entering the affiliation (class) and name, a question, an answer field, and the like. If there are a large number of questions and a plurality of answer sheets 5 are set, a different dot pattern is printed for each of the second, third,... 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.

[Answer sheet, correspondence between electronic pen and students, etc.]
As for the correspondence between the answer sheet, the electronic pen and the student (entrant), in this embodiment, as shown in FIG. 3, the student “Taro” answers the answer sheet 5A using the electronic pen 1A, The student “Jiro” answers the answer sheet 5B using the electronic pen 1B, the student “Saburo” answers the answer sheet 5C using the electronic pen 1C, and the student “Shiro” uses the electronic pen 1D. It is assumed that the student “Goro” answers the answer sheet 5E using the electronic pen 1E. Further, it is assumed that the lecturer (user) “Hanako” operates the aggregation device 2.

  Next, an Anoto dot pattern (coded pattern) printed on the answer sheet 5 will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram illustrating the relationship between the dots of the dot pattern printed on the paper 5 and the values to which the dots are converted. As shown in FIG. 4, 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 paper are determined by the combination of the information thus associated.

  FIG. 5 shows an arrangement of a certain dot pattern. As shown in FIG. 5 (a), 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a unique pattern can be obtained no matter which part of the paper is taken 6 × 6 dots. Yes. The dot pattern formed by these 36 dots holds position coordinates and a dot pattern address (coded pattern address). FIG. 5B is a diagram in which each dot shown in FIG. 5A is converted into a corresponding value based on the regularity shown in FIG. 4 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. As shown in FIG. 6, the electronic pen 1 includes a processor 108 configured by a CPU, a memory 109 such as a ROM and a RAM, a communication unit configured by an antenna, a transmission circuit, and the like inside a housing 101. 111, a battery 112, an LED 105, a CMOS camera 106, a real-time clock 110, a pressure sensor 107, and an ink cartridge 104. The tip of the ink cartridge 104 is a pen tip portion 103, and each student can answer the affiliation (class), name, and question while bringing the pen tip portion 103 of the electronic pen 1 into contact with the answer sheet 5. Can be filled in.

  The battery 112 is for supplying power to each component in the electronic pen 1. For example, the attachment / detachment of the cap containing the magnet is detected by a magnetic sensor (not shown), and the electronic pen 1 itself is turned on / off. 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 detects the pressure applied through the ink cartridge 104 from the pen tip portion 103 when the student writes characters or the like on the answer sheet 5 with the electronic pen 1, that is, the writing pressure, and sends the value to the processor 108. send.

  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 a student writes a character or the like on 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 of a predetermined value or more, The processor 108 determines that the student has started entry, and activates the LED 105 and the CMOS camera 106.

  The LED 105 and the CMOS camera 106 are attached in the vicinity of the pen tip portion 103 of the electronic pen 1. An opening 102 is formed in a portion of the housing 101 facing the LED 105 and the CMOS camera 106. The LED 105 irradiates 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 captures a dot pattern in the area illuminated by the LED 105 and supplies image data of the dot pattern to the processor 108. An imaging region by the CMOS camera 106 is a range including a size of about 2 mm × about 2 mm as shown in FIG. Imaging by the CMOS camera 106 is performed about 50 to 100 times per second.

  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 small amount of infrared reflection, and the portion other than the dot has a large amount of infrared reflection. By discriminating the photographing result of the CMOS camera 106 with a threshold value, it is possible to distinguish the dot area containing carbon from the other area by the difference in the amount of reflected infrared light. Since the ink on which the frame line, characters, etc. of the answer sheet 5 are printed does not absorb in the infrared region, the dot pattern can be easily recognized.

  The processor 108 continuously calculates the XY coordinates (position coordinates) on the paper 5 of the stroke (handwriting) to be entered by the student from the dot pattern of the image data supplied by the CMOS camera 106 while the student is filling in. I will calculate it. That is, the processor 108 converts the dot pattern image data supplied by the CMOS camera 106 into a data array as shown in FIG. 5B, and further converts it into an X coordinate bit value and a Y coordinate bit value. The XY coordinate data and the dot pattern address are calculated from the data array by a predetermined calculation method. The processor 108 then sends the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, dot pattern address, XY coordinate data, and pen ID (electronic pen identification information). Associate. Since the 6 × 6 dot pattern in the answer sheet 5 does not overlap in the answer sheet 5, when the student enters the answer contents with the electronic pen 1, it indicates which position on the sheet the entered position corresponds to. , And can be specified by coordinate calculation by the processor 108.

  The memory 109 stores a pen ID for identifying the electronic pen 1. The pen IDs “pen01” to “pen05” are stored in the respective memories 109 for the electronic pens 1A to 1E (see FIG. 1).

  The communication unit 111 sends time information (time stamp), writing pressure data, dot pattern address, XY coordinate data, and pen information associated with the pen ID directly to the aggregation device 2 or the transfer device 3. To send via. Transmission by the communication unit 111 is immediately and sequentially performed to the aggregation device 2 by a wireless transmission method of Bluetooth (registered trademark).

  Each electronic pen 1 generates entry information and sends it to the aggregation device 2 every time the student enters the answer sheet 5. For example, when the student touches the answer sheet 5 with the pen tip portion 103 of the electronic pen 1 (pen down) and fills in, the electronic pen 1 detects that the pressure sensor 107 detects a writing pressure of a predetermined value or more. The contact with the answer sheet 5 is detected. Then, while irradiating infrared rays with the LED 105, the dot pattern near the pen tip portion 103 is photographed with the CMOS camera 106. The processor 108 calculates the XY coordinate data and the dot pattern address at the contact position on the answer sheet 5 from the image data of the captured dot pattern. The processor 108 generates entry information in which the time information indicating the current time transmitted by the real-time clock 110, the dot pattern address, the XY coordinate data, the pen pressure data, and the pen ID are associated with each other. The data is transmitted to the aggregation device 2.

  In this way, the electronic pen 1 continues to generate entry information and send it to the aggregation device 2 while the student continues to fill in the answer sheet 5. When the student removes the electronic pen 1 from the answer sheet 5 (pen up), the electronic pen 1 stops the entry because the pressure sensor 107 no longer detects a writing pressure exceeding a predetermined value. It is determined that Then, the LED 105 and the CMOS camera 106 are stopped, and transmission of entry information to the aggregation device 2 is stopped.

[Transfer device]
The transfer device 3 will be described with reference to FIG. FIG. 7 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. 7, the transfer device 3 includes a transfer reception unit 31 and a transfer transmission unit 32. The transfer receiving means 31 is a 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.

In the user name column of the user selection list 69, the user name corresponding to the user ID of the individual learning data stored in the storage unit 25 is displayed by the aggregation processing unit 24.

  Then, when the operator selects a desired user from the user selection list 69 with the mouse and clicks the selected user display button 53, the aggregation processing unit 24 displays the selected user's stroke information together with the image of the answer sheet 5. Are displayed in the user stroke information display area 50. In FIG. 10, the user name “Saburo” is selected from the user selection list 69, and the contents entered in the user stroke information display area 50 by using the electronic pen 1 C by the student “Saburo” are the answer sheets 5. It is displayed with the image. 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).

  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 and selects a desired button among the color classification buttons 71 to 76, the aggregation processing unit 24 displays the user selection list 69. A column for displaying the color classification of the selected user name is displayed in the designated color. With this function, an instructor who is an operator can see the answer contents of the student displayed in the user stroke information display area 50, color the way of thinking and the like, and make it easy to see. The user color (classification) information may be set to white when not set.

  The list order sort button 78 is a button for sorting the user list displayed in the user selection list 69 in the order of the list number. In the first embodiment, the order of user IDs shown in FIG. 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 uses the electronic pen after the previous file storage based on the user ID associated with the selected user. The user stroke information received from 1 and stored in the storage area for each user ID of the storage means 25 is cleared, the user stroke information up to the time when the previous file was saved 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.

  In addition, as shown in FIG. 12, file data storage, application settings, and the like may be prepared as function menus in the same manner as general applications. As shown in FIG. 12A, as a pull-down menu of the file menu 84, menus 85 and 86 for reading and saving file data, menus 87 and 88 for saving in an image format, and a menu 89 for closing an application. For example, it is convenient to have a list of execution functions related to general management of applications.

  In addition, the file format for saving file data has a structure in which user stroke information for each user is associated with setting information, so when reading file data, search for specific data from user ID, user color information, keyword information, etc. Then, the searched user stroke information can be displayed in the user stroke information display area 50. Here, the keyword information in FIG. 9 corresponds to the keywords in the user selection list 69 shown in FIG.

  As shown in FIG. 12B, a list of execution functions related to application display such as a full-screen display menu 92 that hides the window frame and maximizes the display area of the application as a pull-down menu of the display menu 91 is prepared. It is convenient to leave.

It is convenient to prepare a list of execution functions related to application settings such as a paper management menu 95 for setting an image of the answer sheet 5 as a background to be displayed and a menu 96 for displaying application version and property information. When these buttons and menus are selected, each function is executed by the aggregation processing means 24.

[List display function]
Next, a list display function by operating the comparison list display button 54 will be described with reference to FIGS.

  In the display state of the display means 26 shown in FIG. 10, before the comparison list display button 54 is clicked, the aggregation processing means 24 designates the display range on the answer sheet displayed in the user stroke information display area 50 with the mouse. It is determined whether it has been done (FIG. 13, step S101). When it is determined that the display range is not designated (step S101: No), the aggregation processing unit 24 defines the display range as the entire answer sheet (step S107). Thereafter, when the aggregation processing unit 24 detects a click on the comparison list display button 54 (step S103: Yes), the entire answer sheet is used as the display range, and the user is included in the display range for each pen ID of each electronic pen 1. It is determined whether or not stroke information exists (step S104). Then, the aggregation processing unit 24 reads the user stroke information of the display range only from the pen ID for which the user stroke information exists, from the storage unit 25, and reproduces the image data of the answer sheet for each user stroke information as a handwriting on the background, As shown in FIG. 14, a list is displayed in the user stroke information display area 50 (step S105).

  At this time, the aggregation processing unit 24 reads and displays the corresponding user name and user color (classification) information from the storage unit 25 near the upper right of each reproduction answer sheet. Furthermore, when the aggregation processing unit 24 receives the entry information sequentially transmitted from the electronic pen 1 even after the list is displayed, the aggregation processing unit 24 stores the entry information for each pen ID in the storage unit 25 and based on the learning data including the entry information. Then, for each pen ID of each electronic pen 1, it is determined whether or not user stroke information exists in the display range (step S104), and only the pen ID for which the user stroke information exists exists, the user stroke information of the display range. Is read from the storage means 25, the handwriting is reproduced, and the display contents of the user stroke information display area 50 are updated and displayed as a list (step S105). As will be described later, when the display range is adjusted by a mouse drag operation or the like (step S106: Yes), whether or not user stroke information exists in the newly adjusted display range for each pen ID again. (Step S104), the user stroke information of the display range is extracted from the storage means 25 only for the pen ID in which the user stroke information exists, and the image data corresponding to the display range of the answer sheet for each user stroke information is used as the background. Are reproduced as handwriting, and the display contents of the user stroke information display area 50 are updated and displayed as a list (step S105).

  On the other hand, as shown in FIG. 15, in the user stroke information display area 50 in the selected user display state in which the user name “Saburo” is selected in the user selection list 69, the operator moves the cursor 98 by dragging the mouse. When the range 99 is moved and designated, the aggregation processing unit 24 detects that the display range is designated by the drag operation (step S101: Yes), and defines the designated range 99 as the display range (step S102). Subsequently, when the aggregation processing unit 24 detects that the comparison list display button 54 is clicked (step S103: Yes), for each pen ID of each electronic pen 1, the specified range 99 in the answer sheet is displayed. It is determined whether user stroke information exists in the same display range (step S104). And only the pen ID in which the user stroke information exists, the user stroke information of the display range is extracted from the storage means 25, and the image data corresponding to the display range of the answer sheet is reproduced for each user stroke information as a handwriting on the background, As shown in FIG. 16, a list is displayed in the user stroke information display area 50 (step S105). Also at this time, the aggregation processing unit 24 reads and displays the corresponding user name and user color (classification) information from the storage unit 25 near the upper right of each reproduction answer sheet.

  Further, when the aggregation processing unit 24 receives the entry information sequentially transmitted from the electronic pen 1 even after the list is displayed, the aggregation processing unit 24 stores the entry information in the storage unit 25 for each pen ID, and the learning data including the entry information is stored. Based on the pen ID of each electronic pen 1, it is determined whether or not the user stroke information exists in the display range (step S104), and only the pen ID in which the user stroke information exists exists in the display range. The information is read from the storage means 25, the handwriting is reproduced, the display content of the user stroke information display area 50 is updated and displayed as a list (step S105). Further, as shown in FIG. 17, when the operator adjusts the display range by moving the cursor 98 in the lower left direction 981 by dragging the mouse in the drawing area of the user stroke information of the user name “Saburo”, the aggregation process The means 24 detects that the display range has been adjusted by the drag operation (step S106: Yes), and again determines for each pen ID whether or not user stroke information exists in the newly adjusted display range ( Step S104). Then, the aggregation processing unit 24 extracts the user stroke information of the display range only from the pen ID for which the user stroke information exists, from the storage unit 25, and sets the image data corresponding to the display range of the answer sheet for each user stroke information as the background. As shown in FIG. 18, the display contents of the user stroke information display area 50 are updated and displayed as a list (step S105).

  As described above, the aggregation processing unit 24 does not need to display the pen ID reproduction answer sheet in which the user stroke information does not exist in the range corresponding to the specified range 99 specified in step S102. It is not displayed in the stroke information display area 50. Therefore, the aggregation processing unit 24 can effectively display the reproduction answer sheet in which the user stroke information exists in the range corresponding to the designated range 99 by using the user stroke information display area 50 to make it easy to see. it can. Further, the aggregation processing unit 24 sequentially receives entry information from the electronic pen 1 in the list display state, and if the user stroke information based on the new entry information exists in the display range, the reproduction answer sheet of the pen ID is also displayed. The display contents of the user stroke information display area 50 are updated and displayed as a list so as to be displayed.

  In step S106, when the display range is enlarged by a mouse drag operation, even if the user stroke information does not exist in the display range before enlargement, the area corresponding to the enlarged area is displayed. For those for which user stroke information exists, the reproduction answer sheet for the pen ID is displayed in the user stroke information display area 50 by the aggregation processing means 24. On the other hand, in step S106, when the display range is reduced by a mouse drag operation, even if the user stroke information exists in the display range before the reduction, the area corresponding to the reduced area is displayed. In the case where the user stroke information does not exist, the reproduction answer sheet for the pen ID does not need to be displayed, and therefore is not displayed in the user stroke information display area 50 by the aggregation processing unit 24. In this way, it is possible to arbitrarily adjust the designated range to be displayed as a list and display a list that reflects the presence of the stroke information after the adjustment.

  Note that the aggregation processing unit 24 displays a frame line around the reproduced image of the answer sheet used for specifying the range to make it stand out, but instead, the display part of the user name may be displayed inverted. In addition, since the operator sets user color (classification) information and keyword information in the comparison list display state, a user other than the user of the reproduced image of the answer sheet displayed in the frame is displayed from the user selection list 69. When selected, the aggregation processing unit 24 may change the reproduction image displaying the frame line to the reproduction image of the answer sheet of the selected user and display it.

  As described above, according to the list display function, the operator (instructor) designates an arbitrary display range by dragging the mouse, so that a portion of the same range is cut out from the reproduced answer sheet, and a plurality of classes are taken. You can display a list of answers for your life. In addition, when displaying a list, if there is a reproduction answer sheet that extends beyond the display range and you want to expand the display range, or if you want to compare a narrower display range in detail, user selection The list display can be updated by adjusting the designated range by operating the mouse while returning to the comparison list display state without returning to the display screen. Therefore, even if the instructor does not move in the classroom, the progress status of each student's answer can be displayed in a list and confirmed sequentially, so that each student's mistakes and trips can be detected early. In addition, by displaying the list-displayed screen on the screen with the projector 4, each student can recognize how to understand other students and the way of thinking. Can be recognized with attention.

(Answer distinction function)
Next, the answer distinction function when the list display screen is projected and displayed on the screen by the projector 4 will be described with reference to FIGS.

  In the comparison list state shown in FIG. 17 and the like on the display means, as shown in FIG. 19, each time the student enters an answer with the electronic pen 1 on the answer sheet 5, the electronic pen 1 receives the stroke information about the answer sheet 5. The entry information including the time information and the pen ID is generated and transmitted to the aggregation device 2 (step S201). In the aggregation device 2, the aggregation individual receiving means 22 receives the entry information from the electronic pen 1, and the aggregation processing means 24 stores the entry information in the storage means 25 (step S301). Then, the aggregation processing unit 24 determines whether or not the user stroke information based on the newly received entry information is included in the display range (step S302). If it is included in the display range (step S302: Yes), the aggregation processing unit 24 further determines whether or not a display signal is output to the projector 4 by the transmission unit 27 (step S303). If the display signal is output (step S303: Yes), the line type information for displaying the user stroke information on the display means 26 is displayed in a color or thickness different from the default line type. The user stroke information included in the display range for each pen ID is updated and displayed in the user stroke information display area 50 (step S304). Specifically, as shown in FIG. 20, the aggregation processing unit 24 projects the comparison list display screen from the projector 4 onto the screen, and then the student “Jiro” displays the answer sheet paper displayed on the screen. The stroke in which “270” is entered in the answer sheet 5B area corresponding to the display area 97 is reproduced in bold red as the answer sheet for the user name “Jiro” and displayed in the user stroke information display area 50.

  During the output of the display signal to the projector 4 by the transmission means 27, the entry information received from the electronic pen 1 is entered by the student using the electronic pen 1 looking at the image projected and displayed on the screen by the projector 4. May be information. However, according to the answer distinction function, when the comparison list screen by the list display function is projected and displayed on the screen by the projector 4, the answer before opening it to each student is explained. By changing the line type of the user stroke information to be displayed and making the answer after the disclosure different, the user can easily distinguish visually.

Second Embodiment
Next, a second embodiment will be described with reference to FIGS. The second embodiment is different from the first embodiment in the algorithm of the list display function, but the other configurations are the same as those in the first embodiment.

  From the display state in the display means 26 shown in FIG. 10, before the comparison list display button 54 is clicked, the aggregation processing means 24 is displayed on the answer sheet displayed in the user stroke information display area 50 by dragging the mouse. It is determined whether or not a range has been specified (step S401), and while it is determined that a display range has not been specified (step S401: No), the display range is defined as the entire answer sheet (see FIG. In step S408), if a click on the comparison list display button 54 is detected in this state (step S409: Yes), the entire display area of the answer sheet is set as the display range, and the user enters the display range for each pen ID of each electronic pen 1. It is determined whether or not stroke information exists (step S405). Then, only the pen ID in which the user stroke information exists, the user stroke information of the display range is read from the storage unit 25, and the image data of the display range of the answer sheet is reproduced for each user stroke information as handwriting on the background. A list is displayed in the display area 50 (step S406: reference diagram 14).

  Further, when the display range is adjusted by dragging the mouse or the like (step S407: Yes), the aggregation processing unit 24 again determines whether or not stroke information exists in the newly adjusted display range for each pen ID. (Step S405), the user stroke information of the display range is extracted from the storage means 25 only for the pen ID for which the user stroke information exists, and the image data corresponding to the display range of the answer sheet for each user stroke information is used as the background. Are reproduced as handwriting, and the display contents of the user stroke information display area 50 are updated and displayed as a list (step S406). This flow is the same as in the first embodiment.

  On the other hand, as shown in FIG. 22, in the user stroke information display area 50 in the selected user display state, when the operator moves the cursor 98 and designates a range 99 by dragging the mouse, the aggregation processing unit 24 performs the drag operation. Is detected (step S401: Yes), and the specified range 99 is defined as the display range (step S402). Furthermore, the aggregation processing unit 24 displays the pop-up menu 201 in the vicinity of the cursor 98 (step S403). The pop-up menu 201 includes, for each function, a “comparison of specified ranges in a list” menu 202, a “display enlarged display of specified range” menu 203, and a “save the specified range as an image” menu 204. In this state, when the aggregation processing unit 24 detects the selection of the menu 202 or the click of the comparison list display button 54 (step S404: Yes), the designated range 99 of the answer sheet is set as the display range, and each electronic pen 1 is displayed. It is determined for each pen ID whether or not user stroke information exists in the same display range (step S405). And only the pen ID in which the user stroke information exists, the user stroke information of the display range is extracted from the storage means 25, and the image data corresponding to the display range of the answer sheet is reproduced for each user stroke information as a handwriting on the background, A list is displayed in the user stroke information display area 50 (step S406).

  Further, when the display range is adjusted by dragging the mouse or the like (step S407: Yes), it is again determined whether or not stroke information exists in the newly adjusted display range for each pen ID (step S405). ), Only the pen ID for which the user stroke information exists, extracts the user stroke information of the display range from the storage means 25, and reproduces the image data corresponding to the display range of the answer sheet for each user stroke information as a handwriting on the background, The display contents of the user stroke information display area 50 are updated and displayed as a list (step S406). Also in the second embodiment, the aggregation processing unit 24 reads and displays the corresponding user name and user color (classification) information from the storage unit 25 near the upper right of each reproduction answer sheet (see FIG. 14). FIG. 16).

  Also, as shown in FIG. 22, when the “display enlarged specified range” menu 203 is selected while the pop-up menu 201 is displayed, the aggregation processing means 24 selects the specified range 99. The user display state is enlarged and displayed in the user stroke information display area 50. When the “save the designated range as an image” menu 204 is selected, the aggregation processing unit 24 stores the designated range in the storage unit 25 as image data.

  Also in the list display function in the second embodiment, as in the first embodiment, the operator specifies an arbitrary display range by dragging the mouse, so that the same corresponding range is obtained for the answer sheet paper to be reproduced. It is possible to display a list of answers for a plurality of students by cutting out the part of.

  The present invention is not limited to the above embodiment.

  In the above embodiment, the entry information transmitted by the electronic pen 1 is stored by the storage unit 25 in the aggregation device 2 in direct association with a preset pen ID. With respect to the storage of such entry information, a list sheet 6 printed with a dot pattern different from the answer sheet 5 as shown in FIG. 23 is prepared, and a user ID is associated with each user area 601 to 606 in the aggregation device 2. Remember. Then, when filling in the answer sheet 5, by tapping any of the user areas 601 to 606 with the electronic pen 1 in advance, the pen ID of the electric 3 pen 1 is associated with the user area on the aggregation device 2 side. The user ID may be stored in association with the user ID, and subsequent entry information by the electronic pen 1 may be stored in association with the user ID. With this configuration, even when a plurality of students use the same electronic pen 1, the user ID associated with the electronic pen 1 can be changed by changing the user area tapped on the name sheet 6. Therefore, whenever the student changes, the electronic pen 1 to be used may be tapped on the corresponding user area.

  In the above embodiment, in the list display function, when the operator adjusts the display range in the comparison list display state, the aggregation processing means 24 detects that in the aggregation device 2 (FIG. 13, Step S106: Yes, Or FIG. 21, step S407: Yes), it is determined again whether the user stroke information for each pen ID is included in the adjusted display range (FIG. 13, step S104, or FIG. 21, step S405). However, when the display range is simply enlarged, it is possible to determine and process whether or not the user stroke information for each pen ID is included in the difference area for only the difference display area.

  In the embodiment, in the answer distinction function, when the aggregation processing unit 24 receives new entry information from the electronic pen 1 in the comparison list display state, does the display range include user stroke information based on the entry information? If it is included (step S302: Yes), it is further determined whether a display signal is output to the projector 4 (step S303), and the display signal is output. If it has been set (step S303: Yes), the line type information of the user stroke information is changed and displayed in the user stroke information display area 50. Regarding such distinction of user stroke information (answer), an operator (instructor) inputs arbitrary time information as an answer deadline time by the input means 21, and the aggregation processing means 24 starts from the electronic pen 1 after the time. It is possible to determine whether or not the user stroke information is based on the received entry information. If the user stroke information is after the time set by the operator, the line type information may be changed and displayed. In order to implement this, a text box for setting the answer deadline time by the input means 21 or a button for setting the pressed time information as the answer deadline time may be prepared on the application. Further, the aggregation processing unit 24 changes the user stroke information after the answer deadline time to a different line type, displays it in the user stroke information display area 50, and outputs a display signal to the projector 4, instead of after the answer deadline time. The user stroke information may not be displayed in the display area 50 or may not be output to the projector 4.

  In the above embodiment, only the pen ID reproduction answer sheet in which the user stroke information exists in the designated range 99 designated is displayed in the display area 50. Steps S104 (refer to FIG. 13) and S405, which are functions thereof, are displayed. (Refer FIG. 21) is abbreviate | omitted and the aggregation process means 24 may display the reproduction answer sheet regarding all pen ID on the display area 50. FIG. When an answer is entered with the electronic pen 1 for the first time after the list is displayed as in the above-described embodiment, the display contents in the display area 50 are updated and displayed in a list so that the reproduced answer sheet is also displayed. When the number of reproduced answer sheets increases one after another, the display size of the reproduced answer sheets is changed one after another to update the display contents of the display area 50, so that steps S104 and S405 are omitted when it becomes complicated and difficult to see. Then, it is preferable to display the reproduction answer sheets for all the pen IDs in the display area 50 from the beginning.

  In the above embodiment, the display range is adjusted by dragging the mouse in the drawing area in which the designated range 99 is set (refer to FIG. 17). The aggregation processing unit 24 may be configured to process the adjustment of the display range by a drag operation on the drawing area related to another pen ID.
