In the example shown in FIG. 11, the position of the bellows of the displayed medaka as a solution to the question “Let's distinguish between a female medaka and a male” is a figure 45J (triangle and ellipse in the example shown in FIG. 11). The written state (drawn state) is shown.

  On the other hand, the teacher 90 performs a patrol between the desks when each child 92 is tackling the problem, and designates the time when the teacher input is displayed on the display unit 45 of the student terminal 40 of the student who writes a noteworthy answer. The icon 45H is designated with the touch pen owned by itself. Thereafter, the teacher 90 writes a mark similar to the extraction target mark 35D stored in the storage unit 33 by the above-described initial setting process on the display surface of the display unit 45 of the student terminal 40, and then designates a teacher input designation icon 45H. Is again specified with the touch pen.

  FIG. 12 shows an example of a problem screen in a state where a mark 45K (in this embodiment, a double line) is written (drawn) by the teacher 90. In the example shown in FIG. 12, a state in which a mark 45K is written near the lower end of the problem display area 45C is shown.

  It should be noted that the teacher 90 specified the teacher input specification icon 45H for the student terminal 40 of any child 92 regardless of whether or not the answer is a noteworthy answer during the patrol. In addition, various information can be written. However, in this case, writing of the same mark as the extraction target mark 35D is avoided for the student terminal 40 that is not the target of screen data extraction by the extraction unit 13.

  On the other hand, the child 92 designates the “end” button 45I with the touch pen when writing of the answer to the question is finished and the inter-desk patrol by the teacher 90 is finished.

  Therefore, in the next step 208, the information input unit 17 makes any input to the display surface of the display unit 45 by the teacher 90 or the child 92 (here, writing with a touch pen, designation of an icon, “end” button 45I). Wait until one of the above is performed).

  In step 208, if the writing with the touch pen is being performed, the information input unit 17 waits until the writing is completed. In this case, the information input unit 17 considers that writing has been completed when the tip of the touch pen is separated from the state in which the touch pen is in contact with the display surface of the display unit 45. However, the present invention is not limited to this mode. For example, it may be considered that the writing is completed when the separated period reaches a predetermined period (for example, 1 second). Moreover, even if the state where the tip of the touch pen is in contact with the display surface of the display unit 45 continues, it may be divided every predetermined period (for example, 5 seconds), and the input may be regarded as completed. Good.

  In the next step 210, the information input unit 17 determines whether or not the input to the display surface of the display unit 45 is an input for designating the “end” button 45I. If the determination is negative, the process proceeds to step 212. .

  In step 212, the information input unit 17 determines whether any input state is selected by determining whether the input to the display surface of the display unit 45 is an input designating any icon. judge. Here, the information input part 17 transfers to step 214, when it becomes affirmation determination.

  In step 214, the information input unit 17 determines whether the designated icon is an icon displayed in each of the writing instrument selection area 45D, the line width selection area 45F, and the writing color selection area 45G, or a teacher input time designation icon 45H. It is determined whether or not. Here, if an affirmative determination is made, the information input unit 17 considers that any writing state has been selected, and proceeds to step 216 to determine whether or not the specified icon is the teacher input designation icon 45H. If the determination is affirmative, the process proceeds to step 218.

  In step 218, the information input unit 17 determines whether or not the designation of the designation icon 45H at the time of teacher input is an odd-numbered designation after the execution of the answer reception process is started, and when the determination is affirmative Since the input by the teacher 90 is designated, the process proceeds to step 220.

  In step 220, the information input unit 17 stores information (hereinafter referred to as “teacher identification information”) for specifying that the writing by the touch pen is the writing by the teacher 90 (hereinafter, referred to as “teacher identification information”) (hereinafter, referred to as “teacher identification information”). (Referred to as “first region”). In step 220, the information input unit 17 thereafter sets the image to be written on the display surface of the display unit 45 to be the type, line width, and color of the writing instrument that is predetermined for the teacher (hereinafter referred to as “the writing instrument”). "Teacher setting"). When the process of step 220 is completed, the process returns to step 208 described above.

  On the other hand, if a negative determination is made in step 216, it is considered that one of the icons displayed in each of the writing instrument selection area 45D, the line width selection area 45F, and the writing color selection area 45G is designated by the child 92. Then, the process proceeds to step 222. Also, if a negative determination is made in step 218, the designation of the teacher input designation icon 45H is regarded as an even designation after the execution of the answer reception process is started, and the routine proceeds to step 222. .

  In step 222, the information input unit 17 uses the first area of the memory 42 to specify information (hereinafter referred to as “student identification information”) for specifying that writing by the touch pen is writing by the child 92 thereafter. Set to. In step 222, the information input unit 17 thereafter sets the image to be written on the display surface of the display unit 45 to have the designated writing instrument type, line width, and color (hereinafter referred to as “for student”). It is called “setting”. When the process of step 222 ends, the process returns to step 208 described above.

  On the other hand, if a negative determination is made in step 214, it is considered that the eraser designation icon 45E has been designated, and the routine proceeds to step 224. In step 224, after that, the information input unit 17 is set so as to erase the writing when there is writing in the portion of the display surface of the display unit 45 where the tip of the touch pen is touched (hereinafter referred to as “setting for erasing”). ").

  In the student terminal 40 according to the present embodiment, when any of the “teacher setting”, “student setting”, and “deletion setting” is performed by the above processing, the state is set. Writes or erases the writing in response.

  On the other hand, if a negative determination is made in step 212, it is assumed that writing to the display surface of the display unit 45 or erasure of writing has been performed with the teacher's touch pen or the child's touch pen, and the routine proceeds to step 226.

  In step 226, when writing is performed with the touch pen, the information input unit 17 stores the image data indicating the written image in a predetermined area of the memory 42, and then returns to step 208.

  At this time, the information input unit 17 stores the image data as follows when the process of step 226 is the second and subsequent processes after the execution of the answer reception process is started.

  That is, the image data indicating the image written subsequent to the writing corresponding to the image data previously stored in the memory 42 by the process of step 226 is continuously stored in the previously stored image data. At this time, the information input unit 17 stores the image data in different storage areas of the memory 42 when the writing is performed by the teacher 90 and when the writing is performed by the child 92. As a result, the image data of the image written by the teacher 90 and the image data of the image written by the child 92 can be handled individually. Whether writing by the teacher 90 or writing by the child 92 at this time is whether the information stored in the first area of the memory 42 is “teacher specifying information” or “student specifying information”. Judgment by whether or not.

  On the other hand, in step 226, when the writing is erased with the touch pen and the image data corresponding to the erased writing is stored in the memory 42, the information input unit 17 stores the image data in the memory 42. And thereafter return to step 208.

  By executing the processing of steps 208 to 226 described above, the drawing is finally performed on the display surface of the display unit 45 of the student terminal 40 in accordance with the writing performed by the child 92 or the teacher 90 and the deletion of the writing. The image data indicating the written image is stored in the memory 42.

  On the other hand, if the determination in step 210 is affirmative, that is, if the “end” button 45I is designated by the touch pen, the process proceeds to step 228.

  In step 228, the transmission unit 18 determines whether or not image data is stored in the memory 42 by the processing in step 226. If the determination is affirmative, the process proceeds to step 230.

  In step 230, the transmission unit 18 transmits the image data stored in the memory 42 as write data to be registered in the above-described write information DB to the server device 50 via the network 80, and then an answer reception process. Exit. At this time, the transmission unit 18 individually transmits the write data written by the teacher 90 and the write data written by the child 92 in a state including identification data for identifying each. At this time, the transmission unit 18 transmits the student terminal ID given to the student terminal 40 and the problem ID of the corresponding problem together with the write data.

  When the write data is received from any of the student terminals 40, the CPU 51 of the server device 50 associates the received write data with the student terminal ID and problem ID received together with the write data, and writes information storage area Store in 53B. At this time, the server device 50 stores the student data as the student data when the received write data is from the child 92, and stores it as the teacher data when the received write data is from the teacher 90.

  On the other hand, if a negative determination is made in step 228, the answer acceptance process is terminated without executing the process in step 230. The write information DB shown in FIG. 4 is constructed as an example by the above answer acceptance processing.

  By the way, in the computer system 20 according to the present embodiment, the teacher 90 causes the teacher terminal 30 to execute the display control program 33B when the answers to the common problems from the respective children 92 are obtained, whereby FIG. The display control process shown is performed.

  In step 300 of the display control process, the receiving unit 12 controls the display unit 35 to display a predetermined problem setting screen. In the next step 302, the receiving unit 12 waits for input of predetermined information. .

  FIG. 14 shows a problem setting screen according to the present embodiment. As illustrated in FIG. 14, a problem ID input area 35 </ b> E is displayed on the problem setting screen according to the present embodiment.

  When the question setting screen shown in FIG. 14 is displayed on the display unit 35, the teacher 90 inputs the question ID assigned to the common question to the input area 35E via the input unit 34. When the teacher 90 finishes inputting the question ID, the teacher 90 designates the “END” button 35 </ b> C displayed on the question setting screen with the touch pen. When the “END” button 35 </ b> C is designated with the touch pen, step 302 is affirmed and the process proceeds to step 304.

  In step 304, the receiving unit 12 receives from the server device 50 the problem data registered in the problem information storage area 53 </ b> A and corresponding to the input problem ID via the network 80. In the next step 306, the extraction unit 13 reads each information of the display target terminal and the extraction target mark 35D stored in the above-described initial setting process from the storage unit 33. In the next step 308, the receiving unit 12 registers the input problem ID and the write data corresponding to the display target terminal registered in the write information storage area 53B from the server device 50 with the corresponding student terminal ID. Together with the network 80.

  As described above, the combination of the problem data received by the process of step 304 and the write data received by the process of step 308 corresponds to the screen data to be extracted by the extraction unit 13.

  In the next step 310, the extraction unit 13 creates screen data indicating an answer result screen in a predetermined format using the data received by the processing in steps 304 and 308. At this time, the extraction unit 13 refers to an image (hereinafter referred to as an “individual display screen”) on which an image displayed on the screen of each display target terminal, that is, an image in which a problem and an image written with a touch pen are superimposed. ) Is created so that the screen data is displayed in a matrix.

  In the next step 312, the extraction unit 13 transmits the created screen data to the electronic blackboard control device 60 via the network 80. When receiving the screen data, the CPU 61 of the electronic blackboard control device 60 controls the electronic blackboard 70 so that the answer result screen indicated by the screen data is displayed on the display unit 71. As a result, the answer result screen is displayed on the display unit 71 of the electronic blackboard 70.

  FIG. 15 shows an answer result screen according to the present embodiment. As described above, on the answer result screen according to the present embodiment, the images 71C of the individual display screen displayed on each display target terminal are displayed in a matrix. In the answer result screen shown in FIG. 15, the name of the child 92 to whom the student terminal 40 on which the individual display screen is displayed is displayed on each individual display screen. For this reason, in the computer system 20 according to the present embodiment, the student terminal ID is associated with information indicating the name of the child 92 to which the student terminal 40 to which the student terminal ID is assigned is distributed, Pre-stored in the storage unit 53 of the server device 50.

  When the answer result screen shown in FIG. 15 is displayed on the display unit 71 of the electronic blackboard 70, the teacher 90 highlights the display area of the image 71C in which the same mark as the extraction target mark 35D registered in advance is written. The “highlight” button 71A is designated with the fingertip. In addition, the teacher 90 designates the “end” button 71 </ b> B with a fingertip when ending the display of the answer result screen. Note that when the “highlight” button 71A or the “end” button 71B is designated, the electronic blackboard control device 60 according to the present embodiment provides the teacher terminal 30 with type information that is information indicating the type of the designated button. It transmits via the network 80.

  Therefore, in the next step 314, the extraction unit 13 waits for the designation of the “highlight” button 71A or the “end” button 71B by waiting for reception of the type information from the electronic blackboard control device 60. To do. In the next step 316, the extraction unit 13 determines whether or not the “highlight display” button 71A is designated based on the received type information. If the determination is negative, the extraction control unit 13 ends the display control process. If the determination is affirmative, the routine proceeds to step 318.

  In step 318, the extraction unit 13 executes a specific image extraction process for extracting the image 71C in which the same mark as the extraction target mark 35D is written as follows.

  First, the extraction unit 13 performs pattern matching between the extraction target mark 35D read by the process of step 306 and the teacher data in all the write data received by the process of step 308. Thereby, the correlation degree which shows the similarity degree between images between the extraction object mark 35D and the image shown by each teacher data is obtained. As a pattern matching technique applied here, a conventionally known technique such as template matching can be cited.

  Next, the extraction unit 13 identifies teacher data in which the degree of correlation exceeds a predetermined reference value. The teacher data specified here is hereinafter referred to as “specific teacher data”. Then, the extraction unit 13 extracts the image 71C including the image indicated by the specific teacher data as the image 71C in which the same mark as the extraction target mark 35D is written.

  When performing the pattern matching, processing for enlarging or reducing the size or processing for rotating is performed on at least one of the extraction target mark 35D and the image indicated by the teacher data. It is good also as a form.

  That is, the teacher 90 often writes the mark 45K to the student terminal 40 at a distance different from the distance to the teacher terminal 30 when the extraction target mark 35D is registered. For this reason, specific teacher data can be specified with higher accuracy by performing enlargement or reduction in accordance with the different distances on at least one of the extraction target mark 35D and the image indicated by the teacher data.

  In addition, since the teacher 90 writes to the student terminal 40 while performing the inter-desk patrol, the teacher 90 often writes the mark 45K at an angle different from the extraction target mark 35D registered in advance. For this reason, the specific teacher data can be specified with higher accuracy by performing the rotation process according to the different angle on at least one of the extraction target mark 35D and the image indicated by the teacher data.

  In the display control processing according to the present embodiment, the extraction target mark 35D is input and registered by handwriting by the teacher 90 who actually writes the corresponding mark in the student terminal 40. For this reason, it is possible to specify the specific teacher data with higher accuracy than when other people input and register.

  In the next step 320, the display unit 14 displays the display area (hereinafter referred to as “highlighted display area”) of the image 71 </ b> C extracted by the processing in step 318 on the answer result screen displayed by the display unit 71 of the electronic blackboard 70. .) Is subjected to predetermined emphasis processing. Specifically, the display unit 14 performs a predetermined emphasis process on the emphasis display area on the answer result screen on the screen data indicating the answer result screen created by the process of step 310.

  In the next step 322, the display unit 14 sends screen data indicating the answer result screen (hereinafter referred to as “emphasized answer result screen”) subjected to the above-described emphasis process to the electronic blackboard control device 60 via the network 80. By sending, the answer result screen is highlighted. When the electronic blackboard control device 60 receives the screen data, the electronic blackboard control device 60 controls the electronic blackboard 70 so that the emphasized answer result screen indicated by the screen data is displayed by the display unit 71. As a result, on the display unit 71 of the electronic blackboard 70, an emphasized answer result screen is displayed in which the image 71C in which the same mark as the extraction target mark 35D is written is emphasized.

  FIG. 16 shows an emphasized answer result screen displayed on the display unit 71 of the electronic blackboard 70 by the process of step 322. As shown in FIG. 16, the emphasized answer result screen according to the present embodiment emphasizes the answer result screen (see also FIG. 15) displayed on the display unit 71 of the electronic blackboard 70 by the process of step 312. The difference is that the display area 71D is highlighted. As shown in FIG. 16, in the present embodiment, the individual highlight display areas 71 </ b> D are masked and displayed as the highlighting process. However, the present invention is not limited to this form. For example, the outer peripheral portion of the highlight display area 71D may be surrounded by a thicker line than the display area of the other image 71C. Further, for example, only the highlighted display area 71D may be displayed in an enlarged form, conversely, a form other than the highlighted display area 71D may be masked, or only the highlighted display area 71D may be blinked or reverse displayed.

  By referring to the emphasized answer result screen shown in FIG. 16, the display image on the display unit 45 of the student terminal 40 in which the answer to be noticed can be easily identified. It becomes possible to support the identification of the children who went.

  In the next step 324, the display unit 14 waits until designation of the “end” button 71B is performed, and thereafter ends the display control processing.

  The teacher 90 performs the subsequent lesson with the highlighted answer result screen shown in FIG. 16 as an example displayed on the display unit 71 of the electronic blackboard 70.

  In the above-described embodiment, the case where the teacher 90 inputs the extraction target mark in advance by handwriting has been described. However, the present invention is not limited to this. For example, it is possible to apply a graphic selected by a selection menu from a graphic group of a plurality of predetermined shapes as an extraction target mark.

  FIG. 17 shows an example of an initial setting screen displayed on the display surface of the display unit 35 by the process of step 100 of the initial setting process (see also FIG. 6). In the initial setting screen shown in FIG. 17, “line” (single line), “double line”, “rectangle”, “circle”, “star”, and “rice” can be selected as the graphic. As a simple figure, it is displayed in the form of a selection menu. From these figures, the teacher 90 designates, with a touch pen, a figure to be written on the display unit 45 of the student terminal 40 that is to be highlighted on the highlighted answer result screen. In addition, although illustration is abbreviate | omitted, the said figure is not restricted to figures, such as the above "line", A mark (check mark),! A mark (exclamation mark) may be applied as the graphic. Similarly, a wavy line, a double wavy line, a dotted line, a flower circle, a triangle, a double circle, a number indicating a score, a symbol (alphabet) indicating an evaluation result, and the like may be applied as the graphic.

  According to this aspect, it is possible to reduce the time and labor when registering the extraction target mark, and the shape of the mark serving as a reference when performing the specific image extraction process is fixed. The extraction accuracy can be further improved. In addition, since these figures and the like are representative ones that are usually described in locations to which attention is paid, writing to the student terminal 40 can be performed without a sense of incongruity.

  In this embodiment, the teacher 90 does not write the same mark as the extraction target mark on the student terminal 40 by hand, but when the teacher 90 designates the position to attach the mark with a touch pen, the teacher 90 selects the position in advance. The extraction target mark may be automatically displayed. In this case, since the shape, size and angle of the extraction target mark registered in advance and the mark displayed on the student terminal 40 match, the extraction accuracy by the specific image extraction process can be further improved.

  Moreover, although the said embodiment demonstrated the case where the kind of extraction object mark registered beforehand was 1 type, it is not limited to this, A plurality of types of extraction object marks are registered beforehand. It is good also as a form. In this case, as shown in FIG. 18 as an example, by performing pattern matching on the basis of a plurality of extraction target marks registered in advance, an image showing a screen on which marks similar to the plurality of extraction target marks are written is obtained. Will be extracted. In this case, the teacher 90 can use each mark properly according to the purpose and the like, and can give more detailed guidance.

  In the above embodiment, image data indicating the problem (question data), image data indicating the image written by the teacher 90 (teacher data), and image data indicating the image written by the child 92 (student data) ) Are stored as different layers. When the highlighted answer result screen is displayed on the electronic blackboard 70, the images indicated by the image data of each layer are displayed in a superimposed manner. However, the present invention is not limited to this form. For example, teacher data and student data may be stored as one layer without being divided. Further, the problem data, the teacher data, and the student data may be collectively stored as one layer.

  FIG. 19 shows an example of a writing information DB in a form in which problem data, teacher data, and student data are stored as one layer. The write data in this case is data indicating an image in which the problem indicated by the problem data and the image indicated by the teacher data and the student data are superimposed. As shown in FIG. 19, in this case, single write data is registered for each combination of the student terminal ID and the problem ID in the write information DB.

  In this case, since the screen data can be handled by a single image data, the convenience in this respect is improved, but the images written by the teacher 90 and the child 92 are mixed. In comparison, the accuracy of the specific image extraction process is reduced. In order to deal with this problem, for example, it is preferable to make the conditions different between the image written by the teacher 90 and the image written by the child 92. The conditions in this case can be exemplified by color, line width, type of writing instrument, and the like. Thus, the image written by the teacher 90 and the image written by the child 92 have different characteristics. For this reason, the accuracy of the specific image extraction process can be improved by applying a mark having image characteristics written by the teacher 90 as the extraction target mark.

  Moreover, although the said embodiment demonstrated the case where writing with respect to the display surface of a display part and designation of an icon were performed with a touch pen, it is not limited to this. For example, writing on the display surface may be performed by a human fingertip instead of the touch pen. In this case, both the teacher 90 and the child 92 do not need to use a touch pen, and convenience and operability are improved.

  In the above embodiment, the problem information DB and the write information DB are stored in the server device 50. However, the present invention is not limited to this. For example, the problem information DB and the writing information DB may be held in the teacher terminal 30. In this case, the write data transmitted from the student terminal 40 is transmitted directly to the teacher terminal 30 instead of the server device 50. In this case, since the server device 50 is not necessary, the cost for constructing the computer system 20 can be reduced as compared with the above embodiment.

  In the above embodiment, the case where the initial setting process and the display control process are executed in the teacher terminal 30 has been described. However, the present invention is not limited to this. For example, the server apparatus 50 performs the initial setting process and the display control process. May be executed. As a form in this case, the initial setting program 33A and the display control program 33B shown in FIG. 2 are stored in the storage unit 53 of the server device 50, and the CPU 51 executes these programs. .

  Moreover, although the case where problem information DB was memorize | stored by the server apparatus 50 was demonstrated in the said embodiment, it is not limited to this, For example, problem data is stored in server apparatuses, such as a publishing company which provides a problem collection. It may be registered. In this case, the teacher terminal 30 and the student terminal 40 download the problem data to be used via the network 80 or the like.

  Moreover, although the said embodiment demonstrated the case where an answer result screen and an emphasis answer result screen were displayed with the electronic blackboard 70, it is not limited to this. For example, the answer result screen and the emphasized answer result screen may be displayed by the teacher terminal 30. In this case, since the electronic blackboard 70 and the electronic blackboard control device 60 are not necessary, the cost for constructing the computer system 20 can be reduced as compared with the above embodiment.

  Moreover, although the said embodiment demonstrated the case where the teacher input time designation | designated icon 45H was always displayed on the student terminal 40, it is not limited to this. For example, the teacher input designation icon 45H may be displayed only on the student terminal 40 where the teacher 90 is closer than a predetermined distance (for example, 50 cm). As a specific example, for example, the touch pen possessed by the teacher 90 or the teacher terminal 30 is provided with a transmitter that emits a radio signal with a predetermined frequency and a predetermined intensity, while each student terminal 40 can receive the radio signal. A receiver is provided. The student terminal 40 displays the teacher input designation icon 45H only when the wireless signal is received by the receiver. As another specific example, a form in which the teacher input designation icon 45H is displayed only when a predetermined password is input can be exemplified. In this case, the designation of the designation icon 45H at the time of teacher input by the child 92 can be suppressed as compared with the above embodiment.

  Moreover, although the said embodiment demonstrated the case where it displayed on the electronic blackboard 70 collectively only for the screen of the display object terminal designated beforehand, it is not limited to this. For example, all the screens of the student terminals 40 distributed to all the children 92 belonging to the class may be collectively displayed on the electronic blackboard 70.

  Moreover, although the said embodiment demonstrated the case where the said reference value was made into the fixed value, it is not limited to this, You may make this reference value changeable. As an example of this case, in the above-described initial setting process, as shown in FIG. 20 as an example, an input area 35F for specifying a reference value is provided on the initial setting screen, and the above-mentioned reference is set via the input area 35F. The form which inputs a value is illustrated.

  In the above embodiment, a case has been described in which only one type of mark is registered as the extraction target mark 35D, and pattern matching is performed using the mark, but the present invention is not limited to this. For example, a plurality of marks may be registered in advance in the same type of extraction target mark 35D, and pattern matching may be performed using a mark having the highest degree of correlation in the past.

  Moreover, although the said embodiment demonstrated the case where the extraction object mark 35D was registered at the time before receiving the screen data from each student terminal 40 by the teacher terminal 30, it is not limited to this. Absent. For example, the extraction target mark 35D may be registered after receiving the screen data and before executing the specific image extraction process. That is, the extraction target mark 35D may be registered before the specific image extraction process is executed.

  Although not particularly mentioned in the above embodiment, when the answer result screen and the emphasized answer result screen are displayed by the electronic blackboard 70, the teacher terminal 30 may display the same screen. In this case, since various operations performed on the answer result screen and the emphasized answer result screen can be performed by operations on the teacher terminal 30, the convenience can be further improved.

  Moreover, although the case where the electronic blackboard 70 was controlled by the electronic blackboard control apparatus 60 was demonstrated in the said embodiment, it is not limited to this. For example, the electronic blackboard 70 may be directly controlled by the teacher terminal 30. In this case, since the electronic blackboard control device 60 is not necessary, the cost for constructing the computer system 20 can be reduced.

  In the above-described embodiment, the case where the display control program according to the disclosed technique is applied to a computer system in an education field has been described. However, the present invention is not limited to this.
