The display order is set according to the expanse or the quantity of the stroke groups for every user. The learning system controls display means 26 to display the stroke groups for each of the plurality of users.

Description

  The present invention relates to a learning system, a computer apparatus, and a program capable of displaying contents entered on a plurality of sheets on a terminal device in a system for storing contents entered on a sheet with an electronic pen.

  An electronic pen that digitizes written information has been developed. As a representative example, “Anot pen” developed by Swedish company Anoto is known. Anotopen is used with dedicated paper on which a predetermined dot pattern is printed. In addition to the usual ink cartridge for writing letters, etc., the anotopen has a small camera for imaging the dot pattern printed on the dedicated paper and the position coordinates on the dedicated paper from the captured dot pattern. A processor for calculation and a data communication unit for transmitting calculated position coordinates and the like to an external device are mounted. When a user writes characters on the special paper with an anotopen or puts a check mark on the image designed on the special paper, the small camera captures the dot pattern printed on the special paper as the pen moves. The entry information such as characters and images written by the user is recognized from the continuous position coordinates calculated by the processor. This entry information is transmitted from the Anotopen to a nearby computer such as a personal computer or mobile phone by the data communication unit (see, for example, Patent Document 1). Further, a rotation correction processing function for correcting the arrangement of dots on the image caused by the angle of the electronic pen facing the dot pattern is described in, for example, Patent Document 2.

  Patent Document 3 discloses a technique for applying such a system including an electronic pen and a computer device to a class. That is, according to Patent Document 3, each student enters the contents of the lesson on dedicated paper with an electronic pen. At this time, entry information is sequentially transmitted from the electronic pen to the computer device for each student, and based on these entry information, strokes indicating the entry contents on the dedicated paper are drawn and displayed on a screen or the like. The Specifically, when the teacher performs a predetermined operation on the computer device, a stroke indicating the content entered on the dedicated paper is drawn in each entry area for each student, the size of which is fixed in advance. Then, a list in which each entry area for each student is listed is displayed on a screen or the like.

Japanese Patent No. 3874498 Special table 2003-529853 gazette JP 2009-586479 A

  However, in the technique according to Patent Document 3, only the user's stroke group designated by the computer device is displayed. Therefore, unless the user's stroke group is specified by the computer device, each student cannot grasp the degree of progress from the description of the other students.

  The present invention has been made in view of such a situation, and an object of the present invention is to make it possible to grasp the degree of progress of written contents of each student in a system for storing contents written on a sheet by an electronic pen. And

  The learning system according to the present invention includes a plurality of sheets that are provided with a coding pattern and that can be used by each of a plurality of users, reads the coding pattern, and transmits information about the coding pattern as entry information. A learning system comprising: a plurality of electronic pens that can be used by each of the users; and a computer device that receives stroke information from each of the plurality of electronic pens and executes a stroke drawing process. Receiving means for receiving entry information transmitted from each electronic pen, and display order of each of the plurality of stroke groups drawn based on each of the entry information for each of the plurality of users is received by the receiving means. The display order setting means for setting based on the entry information for each of the plurality of users, and the display order setting means Display control means for executing control to display the stroke group for each of the plurality of users in the display order, the display order setting means according to the spread or amount of stroke groups of each user, The display order of the stroke group for each user is set.

According to this configuration, when a user fills in a sheet on which a coded pattern is provided with an electronic pen, information on the coded pattern is transmitted from the electronic pen as written information. The receiving means of the computer device receives the entry information transmitted from the electronic pen.
The display order setting means sets the display order of each stroke group for each of a plurality of users according to the spread or amount of the stroke group of each user. The display control means executes control for displaying the stroke groups for each of the plurality of users including the stroke groups drawn based on the entry information for each of the plurality of users in the display order set by the display order setting means. To do. Then, the display order setting unit displays the stroke group in a variable display order for each user in accordance with the spread or amount of the displayed stroke group.
Therefore, since the display order of each of the stroke groups for each of the plurality of users varies depending on the spread or amount of stroke groups drawn based on the user's entry, the student who is a user can use each user's stroke group. It can be visually recognized that the display order changes. This allows the student student to compare the order in which his / her stroke group is displayed with the order in which his / her other student's stroke group is displayed, and so on. It is possible to check the spread or amount filled in by students. Therefore, by comparing the display order in which each stroke group is displayed, it is possible to grasp the degree of progress of the written amount of each student.

In the learning system, the display order setting means may be configured to set a predetermined number of stroke groups from the top in the order of spread or quantity of stroke groups of each user.
According to this configuration, the display order is set for a predetermined number of higher ranks among the stroke groups of the users that are expanded or displayed among the users. Accordingly, it is possible to display only the upper predetermined number of strokes whose spread or amount is displayed, and not to display the lower ones with less strokes drawn.

In the learning system, the display order setting unit may be configured to reset the display order according to the state of each user's stroke group at that time each time the set stroke group is displayed in a round. .
According to this configuration, since the state of the stroke group changes with the reception of the entry information while time elapses due to the display by the display order, the display order is changed according to the spread of the stroke group or a change in the amount. Can be made.

Further, the computer device according to the present invention reads a plurality of sheets provided with a coding pattern, which can be used by each of a plurality of users, and the coding pattern, and transmits information about the coding pattern as entry information. A computer device used in a learning system comprising: a plurality of electronic pens that can be used by each of the plurality of users; and a computer device that receives stroke information from each of the plurality of electronic pens and performs a stroke drawing process. The receiving means for receiving the entry information transmitted from each electronic pen, and the display order of each of the plurality of stroke groups drawn based on each of the entry information for each of the plurality of users is received by the receiving means. Display order setting means for setting based on the received entry information for each of the plurality of users, and the display order setting Display control means for executing control for displaying the stroke groups for each of the plurality of users in the display order set by a stage, wherein the display order setting means is a spread or amount of stroke groups for each user. The display order of the stroke group for each user is set according to the above.
With this configuration, since the display order of the stroke groups for each user varies according to the spread or amount of stroke groups drawn based on the user's entry, the students who are users can display the stroke groups of each user. It can be visually recognized that the order changes. This allows the student student to compare the order in which his / her stroke groups are displayed with the order in which the other student's stroke groups are displayed, thereby increasing the extent or amount of strokes he / she has entered. The spread or amount of strokes entered by other students can be confirmed as appropriate. Therefore, by comparing the display order in which each stroke group is displayed, it is possible to grasp the degree of progress of the written amount of each student.

  Further, the program according to the present invention is characterized by functioning as the above computer apparatus. The computer apparatus according to the present invention can be realized by installing this program in the computer apparatus and causing it to function.

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

[Learning system configuration]
FIG. 1 shows a configuration of a learning system 10 according to the present embodiment. As shown in FIG. 1, the learning system 10 according to the present embodiment includes an electronic pen 1-1 to 1-n, an aggregation device 2, a transfer device 3 provided as necessary, a projector 4, and a worksheet. 5-1 to 5-n and a screen 6.
Hereinafter, when it is not necessary to individually distinguish the electronic pens 1-1 to 1-n, these are collectively referred to simply as “electronic pen 1”. Similarly, hereinafter, when it is not necessary to individually distinguish the worksheets 5-1 to 5-n, these are collectively referred to as “worksheet 5”.

Each student (user) is provided with one electronic pen 1 and a worksheet 5 (may be in the form of a notebook). An electronic pen 1 is used as the electronic pen 1, and a dot pattern is printed on the worksheet 5.
Thereby, each student (user) can enter a handwritten stroke group (answer) with the electronic pen 1 on the distributed worksheet 5. During the entry of the handwritten stroke group, as a rule, entry information is wirelessly transmitted from the electronic pen 1 to the aggregation device 2 by Bluetooth (registered trademark). Note that “in principle” is because entry information may be wirelessly transmitted to the aggregation device 2 via the transfer device 3 as described later.
Note that further details of the electronic pen 1 will be described later with reference to FIG. 5 and the like, and further details of the worksheet 5 will be described later with reference to FIG.

  The aggregation device 2 is composed of a computer device such as a laptop personal computer. When the aggregation device 2 receives the entry information from the electronic pen 1, based on the entry information, the aggregation device 2 draws and records a stroke group similar to the handwritten entry on the worksheet 5, and the projector 4. Through the screen 6.

The aggregation device 2 can directly receive the entry information from the electronic pens 1-1 to 1-n by wireless communication. However, when the number n of the electronic pens 1-1 to 1-n that transmit the entry information is large, or when the meeting place where the student answers is far away or the like, it is out of the wireless communication range of the aggregation device 2. The transfer device 3 is further provided in the learning system 10.
The transfer device 3 is configured by a laptop personal computer or the like, and relays entry information transmitted from at least a part of the electronic pens 1-1 to 1-n to transfer it to the aggregation device 2. At this time, the transmission of data from the transfer device 3 to the aggregation device 2 may be performed by a TCP / IP (Transmission Control Protocol / Internet Protocol) communication method via, for example, a LAN (Local Area Network).

  The projector 4 receives information indicating the display content of the screen from the aggregation device 2 and projects and displays the screen of the aggregation device 2 on the screen 6 based on the information.

[worksheet]
FIG. 2 is a schematic diagram showing a worksheet 5 as an entry sheet.
A worksheet 5 is distributed to each student. The dot pattern printed on the worksheet 5 is printed with ink containing carbon that absorbs infrared rays, and the line indicating the entry frame is printed with ink that does not absorb in the infrared region. Each worksheet 5 on which such a dot pattern is printed has a user area 51 (details will be described later with reference to FIG. 6). Also, each worksheet 5 has, as a problem, “mind map (registered trademark)”, “—how to think about energy”, and “energy” character strings that have no absorbability in the infrared region. Is printed. Although not shown in the drawings, each worksheet 5 may be printed with an entry column for entering the affiliation (class) and name, an answer column, and the like with ink that does not absorb in the infrared region.

[Dot pattern]
Next, an Anoto dot pattern (coded pattern) formed on the worksheets 5-1 to 5-n will be described.

  FIG. 3 is a diagram for explaining the relationship between dots in a dot pattern and 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. That is, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left, and right are shifted from the reference position of the grid (the intersection of the vertical and horizontal lines). 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 worksheet 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. 4 (A), 6 × 6 dots are arranged within a range of about 2 mm in length and width so that a unique pattern can be obtained no matter which part of the worksheet 5 is taken with 6 × 6 dots. ing. The dot pattern formed by these 36 dots holds the position coordinates. FIG. 4B is a diagram in which each dot shown in FIG. 4A is converted into a value associated with 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. 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 that includes ink, and the user brings the pen tip portion 103 of the electronic pen 1 into contact with the worksheet 5 to stroke characters (handwritten strokes). Or tapping (tapping the worksheet 5 with the pen tip 103). Here, contact of the pen tip portion 103 of the electronic pen 1 with the worksheet 5 is referred to as pen-down, and removal of the pen tip portion 103 from the contact (contact) state is referred to as pen-up. 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. Further, a trajectory having substantially the same trajectory as the stroke is drawn on the worksheet 5 by the ink flowing out from the pen tip portion 103 onto the worksheet 5 from the pen down to the pen up of the electronic pen 1.

  The battery 112 is for supplying power to each component in the electronic pen 1, and is configured to turn on / off the power of the electronic pen 1 itself by, for example, detaching a cap (not shown) of the electronic pen 1. You may let them. 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 user writes or taps a character or mark on the worksheet 5 with the electronic pen 1, that is, the writing pressure. Transmit 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 user writes a letter of an answer to a question on the worksheet 5 with the electronic pen 1, the pen pressure is applied to the pen tip 103, and when the pressure sensor 107 detects a writing pressure higher than a predetermined value, the processor 108 determines that the user has started filling in and activates the LED 105 and the CMOS camera 106. Then, the communication unit 111 associates pen-down information detected by the pressure sensor 107 with a pen ID described later, and transmits it as entry information to the aggregation device 2 (or the aggregation device 2 via the transfer device 3). Further, when the user finishes entering one stroke and releases the electronic pen 1 from the worksheet 5, the pressure sensor 107 detects pen-up because the writing pressure exceeding a predetermined value is not 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 (or the aggregation device 2 via the transfer device 3).

  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 worksheet 5. The region is slightly shifted from the position where the pen tip portion 103 contacts the worksheet 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 the ink material of dots absorbs infrared rays, the infrared rays irradiated by the LED 105 are absorbed by 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 dot area and other areas can be distinguished by providing a threshold value based on the difference in the amount of reflected infrared light. 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 performs X and Y coordinates (simply “position coordinates”) on the worksheet 5 of strokes (handwriting) to be entered by the user from the dot pattern of the image data supplied by the CMOS camera 106 while the user performs the entry. , Also called “coordinate information”). 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, Y coordinate data is calculated from the data array by a predetermined calculation method. Note that 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 executes the function during coordinate calculation. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, the pen pressure data, and the X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. Note that the 6 × 6 dot pattern in each of the worksheets 5-1 to 5-n does not overlap in the worksheet 5, so that the user selects the worksheets 5-1 to 5-n as electronic When the pen 1 is tapped or a character or the like is entered, it can be specified by coordinate calculation by the processor 108 which position of the worksheet 5-1 to 5-n the tapped or entered position corresponds to. Similarly, since the 6 × 6 dot pattern in the worksheet 5 does not overlap in the worksheet 5, it is entered when the user taps the worksheet 5 or enters characters or the like with the electronic pen 1. It is possible to identify which position of which worksheet 5 the corresponding position corresponds to by the coordinate calculation by the processor 108.

  The memory 109 stores property information such as a pen ID such as “pen01” for identifying the electronic pen 1, a pen manufacturer number, and a pen software version. Then, the communication unit 111 associates the pen ID with the coordinate attribute information (time information, writing pressure data, and X, Y coordinate data) and aggregates the information as entry information via the aggregation device 2 (or the transfer device 3). To device 2). 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 entry information (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, since one stroke is drawn based on one or a plurality of X and Y coordinates (coordinate points), the aggregation device 2 draws one stroke based on the pen-down information and the pen-up information. Recognize one or a plurality of coordinate attribute information necessary for. As described above, a set of coordinate attribute information generated by the electronic pen 1 when one stroke is entered by the user is referred to as “stroke information”. The pen tip 103 transmits the pen pressure to the pressure sensor 107 via the ink cartridge 104.

[Processing flow of aggregation device]
Next, with reference to FIG. 15, a processing flow of the slide show processing of the aggregation device 2 will be described.
FIG. 15 is a flowchart for explaining a series of slide show processing executed by the aggregation device 2.

In the storage unit 24, each user ID and a user name are stored in association with each other as definition information with respect to a unique pen ID held by the electronic pen 1. Therefore, the aggregation device 2 processes the entry information by distinguishing the user based on the pen ID included in the received entry information.
Under such a premise, first, when each user taps or writes a handwritten stroke with respect to a predetermined worksheet 5 with each electronic pen 1, the electronic pen 1 collects each generated entry information. The data is transmitted to the device 2 or to the aggregation device 2 via the transfer device 3. Specifically, at the time of pen down, the electronic pen 1 generates each entry information in which the pen down information and each pen ID are associated, and the created entry information is sent to the aggregation device 2 or via the transfer device 3. 2 to send. When the contact state of the electronic pen 1 with the worksheet 5 continues due to the entry of a handwritten stroke or the like, the electronic pen 1 obtains coordinate attribute information including coordinate information calculated by imaging a dot pattern and each pen ID. The associated entry information is continuously generated and sequentially transmitted to the aggregation device 2 or to the aggregation device 2 via the transfer device 3. At the time of pen-up, the electronic pen 1 generates each entry information in which pen-up information and each pen ID are associated with each other, and transmits the entry information to the aggregation device 2 or to the aggregation device 2 via the transfer device 3.

The aggregation device 2 is triggered by the click of the setting button 73 after the slide show setting menu 601 is clicked by the user's mouse operation and a predetermined setting is performed on the slide show setting window 606 shown in FIG. Start the slide show according to the setting conditions.
In the aggregation device 2, the first process is started when the communication unit 33 becomes communicable with the electronic pen 1, and thereafter, entry information of the registered pen ID is transmitted from the electronic pen 1. The process is repeated every time it comes.

  First, the information processing means 251 sets the slide show end process interruption permission state (step S11). By entering this interrupt enabled state, even during the subsequent steps S12 to S14, the “ESC” key is pressed, and interrupt processing described with reference to FIG. That is, when it is detected that the “ESC” key is pressed, the information processing means 251 forcibly ends the slide show process.

Subsequently, the aggregation device 2 determines the “setting order” (order of stroke number, order of spreading of strokes, or order of user ID) set on the slide show setting window 606 from the current stroke drawing state for each user, The sheet to be displayed and the display order thereof are specified by “display target” (specified by the number of upper sheets or all sheets) (step S12).
In other words, when the “order of strokes” button 701 is selected as the “setting order” in the slide show setting window 606, the display order setting means 252 displays the stroke in the drawing state for each user at the time of step S12. In the descending order of the number, the number of upper sheets selected by “display target” or all the sheets are set as display target sheets.
In the slide show setting window 606, when the “stroke order” button 702 is selected as the “setting order”, the display order setting unit 252 displays the stroke in the stroke drawing state for each user at the time of step S12. In the order of spread, the number of upper sheets selected by “display target” or all the sheets are set as display target sheets.
When the “user ID order” button 703 is selected as the “setting order” in the slide show setting window 606, the display order setting unit 252 displays the number of upper sheets selected in “display target” in the order of the user ID number. Minutes or all sheets are set as display target sheets.

  Next, the display control unit 253 executes control for sequentially displaying the worksheet 5 specified in step S12 on the display unit 26 for each display time set per slide sheet setting window 606 (step S13). ).

  When the display control unit 253 finishes displaying all the specified worksheets 5 (step S14), the process returns to step S12.

When returning from step S14 to step S12 again, time has passed since the previous processing in step S12. In addition, the aggregation device 2 receives entry information from the electronic pen 1 of each user as needed to perform stroke drawing processing. For this reason, the stroke drawing state for each user changes between the current processing at step S12 and the previous processing at step S12. Therefore, in step S12, the display order setting unit 252 respecifies the sheet to be displayed and the display order in the “setting order” and “display target” set on the slide show setting window 606 each time processing is performed.
In this way, the aggregation device 2 repeats the processing of steps S12 to S14 and continues the slide show processing unless interrupt processing is performed by pressing the “ESC” button.

Next, with reference to FIG. 16, the processing flow of the interrupt processing of the aggregation device 2 will be described.
FIG. 16 is a flowchart for explaining a series of interrupt processing executed by the aggregation device 2.
The interruption process is a process executed independently of the slide show process of FIG. 15 (may be executed in parallel), and is started by pressing the “ESC” key.

  The information processing means 251 detects pressing of the “ESC” key (step S31). Thereby, the information processing means 251 forcibly ends the slide show process. When this process ends, the interrupt process ends.

[Effects of this embodiment]
As described above, according to the present embodiment, when each user fills in the work sheet 5 provided with the coding pattern with the electronic pen 1, information regarding the coding pattern is transmitted as the filling information. The entry information transmitted from the electronic pen 1 is received by the aggregated individual receiving unit 20 of the aggregation device 2 or the aggregated transfer receiving unit 21 of the aggregation device 2 via the transfer device 3.
Then, the display order setting means 252 of the aggregation device 2 determines the display order of each user's drawing stroke group according to the entry information received for each of the plurality of users and the set display order, and displays the slide show. Display in a manner. Specifically, the display order setting unit 252 determines the display order in which a plurality of stroke groups are displayed in the order of the spread or amount of stroke groups whose display is controlled by the display control unit 253.
Thus, the display order in which a plurality of stroke groups are displayed changes according to the spread and amount of entry information entered by a plurality of users. From this, the student, who is a user, confirms the spread and amount of information entered on the worksheet 5 of other students as appropriate by visually confirming that the display order in which a plurality of stroke groups are displayed is switched. , It is possible to grasp the degree of progress of the written contents of each student.

[Modification]
The present invention is not limited to the above embodiment.

  For example, instead of determining the display order by the number of strokes as the amount of stroke groups, the display order can be determined in the order of the integrated length of strokes corresponding to the entry information of each user. In this case, the display order setting unit 252 calculates the integrated length of the strokes whose display is controlled by the display control unit 253. Then, the display order setting unit 252 sets the display order according to the calculated integrated stroke length for each user.

  In the above embodiment, the target to use the electronic pen 1 is the worksheet 5, but is not particularly limited to this, and may be any writing medium on which an Anoto dot pattern is printed. Further, the coding pattern, the entry information, and the electronic pen are not limited to the Anoto system.

  The series of processes described above can be executed by hardware or can be executed by software.

  In the present specification, the step of describing the program recorded on the recording medium is not limited to the processing performed in chronological order according to the order, but is not necessarily performed in chronological order, either in parallel or individually. The process to be executed is also included.
