JP5136769B2 - Terminal device and program for managing entry progress with electronic pen - Google Patents

Description

  The present invention relates to a terminal device and a program for managing the progress of entry with an electronic pen, and more particularly to a terminal device and a program for collectively processing entry information transmitted from a plurality of electronic pens.

  2. Description of the Related Art Conventionally, various systems for converting handwritten information into electronic data using an electronic pen have been realized. For example, there are an electronic medical record system, an electronic learning system, and an electronic scoring system. If you use a tablet-type electronic pen input terminal, the completed form will not remain, so you will need to put the paper on the tablet. Also, terminal operation is required and it cannot be used in the same way as paper. Furthermore, it is necessary to secure a space for placing the terminal.

  Therefore, an electronic pen that can be used in the same way as writing on paper was developed. As such an electronic pen, Anoto pen developed by Anoto in Sweden is well known. Anotopen is used together with dedicated paper (dedicated paper, anoto pattern paper) on which a predetermined dot pattern (coded pattern) is printed. On the Anoto pattern paper, a pattern composed of very small dots (lattice with an interval of about 0.3 mm) is printed. With this pattern, the electronic pen acquires coordinates. You can read what was written by writing characters on the Anoto pattern paper that printed the form of the form.

  At the tip of the anotopen, there are an ink cartridge and a miniature camera. A processor and a data communication unit are mounted inside the pen. The user can write letters on an exclusive paper with annot pen, and can put a check mark on an image designed on the exclusive paper. Since it can be used as an ordinary ballpoint pen, you can leave what you write on plain paper. When writing, the dot pattern printed on the special paper is photographed with a micro camera as the pen moves. Based on the captured dot pattern, the position coordinates on the dedicated paper are acquired. In this way, the Anoto pen captures information written on a dedicated paper into the pen as digital information with a micro camera at the nib. The acquired position coordinates and the like are transmitted to a nearby terminal device such as a personal computer or a mobile phone by the data communication unit of Anotopen. Entry information such as characters and patterns written by the user is recognized by the terminal device based on continuous position coordinates (Patent Document 3).

  Information that can be acquired with the anotopen includes position information of the pen tip on the dedicated paper, pen trajectory (stroke), writing speed, writing pressure, writing time, pen tilt, and the like. Data input from the anotopen to the terminal device can be recognized and converted into a character string, and the coordinates on the dedicated paper can be associated with the acquired data and managed in the database. Furthermore, by defining the layout of the form and the record items laid out on the dedicated paper, the operation can be made almost the same as the form on the normal paper.

  There has been proposed a learning scoring system that efficiently counts the results of scoring such as a mock test using such an electronic pen (Patent Document 7). A system has also been proposed in which shared learning data of a plurality of students is stored in a storage device and learning data is provided in response to access from a student terminal (Patent Document 2). In addition, a system has been proposed in which a student enters an answer on a question sheet with an electronic pen, and the contents written on each electronic pen are collectively created for each same question sheet to store a file ( Patent Document 10). Below are some examples of prior art related to learning systems and electronic pens.

  The "electronic scoring system" disclosed in Patent Document 1 summarizes the answer images read from a large number of answer sheets for each question, and scores the answer of the question according to the ability of the grader, thereby simplifying the scoring work.

In the local mode, the multi-participant terminal performs cursor control on the participant display device by operating the pointing device. At the same time, in the remote mode, the cursor on the shared display device is controlled by operating the pointing device. In the remote mode, the cursor can be controlled and written on the shared display device in parallel from a plurality of participant terminals, and the conference proceeds.

  The “Kanji stroke order learning system” disclosed in Patent Document 6 uses an electronic pen to correctly acquire the stroke order of Kanji characters. When the learner enters kanji on the kanji practice form with the electronic pen, stroke data relating to the stroke order when the kanji is written from the kanji practice form is acquired. The acquired stroke data is transmitted by wireless communication. The stroke data transmitted from the electronic pen is received. In the stroke order recording database, stroke order data relating to the correct stroke order of each Chinese character is recorded. The stroke data received from the electronic pen is compared with the stroke order data recorded in the stroke order recording database to determine whether or not the learner's kanji stroke order is the correct stroke order.

  The “scoring system” disclosed in Patent Document 7 is capable of efficiently and accurately obtaining a scoring result such as a mock test and performing processing such as tabulation by using an electronic pen. A grader enters a scoring symbol such as a circle or cross with an electronic pen on an answer sheet on which an examinee has written an answer. The stroke of the scoring symbol drawn on the answer sheet is acquired as scoring data and input to the scoring system. Strokes corresponding to the scoring symbols and correction symbols are extracted from the scoring data, and the strokes are recognized by referring to symbol information indicating the characteristics of the individual scoring symbols and correction symbols. As a recognition result, a scoring symbol or a correction symbol corresponding to the stroke is specified. Based on the recognition result thus obtained, a scoring result is specified and output. Therefore, the scoring person simply enters a scoring symbol or the like on the answer sheet with the electronic pen, and the data of the scoring result is generated and can be used for subsequent tabulation or analysis.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best mode for carrying out the invention will be described in detail with reference to the drawings.

<First Embodiment>
In the first embodiment according to the present invention, the data from the electronic pen of the student of the problem exercise class is transferred to an aggregation device (terminal device) directly or via a transfer device and aggregated, and each student's answer status It is a progress management system that displays a list in real time.

[System configuration of progress management system]
FIG. 1 is a system configuration diagram of a progress management system 10 in the present embodiment. As shown in FIG. 1, the progress management system 10 fills in answer sheets 5A, 5B,... (5) distributed to each student and the answer sheet 5, and sends the entered information to the outside via Bluetooth ( (1) electronic pens 1A, 1B,... (1) for wirelessly transmitting such as registered trademark), and aggregation for receiving entry information transmitted from each electronic pen 1 and displaying the entry contents and the like on a display (display means) And a device (terminal device) 3. In FIG. 1, the aggregation device 3 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 to which the entry information is transmitted is small. If there are many cases, or the venue where the students answer is out of the range of the wireless communication due to a remote location, etc., the entry information transmitted from other electronic pens 1D, 1E,. A transfer device 2 for transferring to can be provided. At this time, transmission of data from the transfer device 2 to the aggregation device 3 may be performed by a TCP / IP communication system 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 transfer device 2 or the aggregation device 3. The projector 4 is a device that receives display information from the aggregation device 3 and projects and displays the screen of the aggregation device 3 on the screen 6. As the projector 4, a liquid crystal projector or the like can be used.

[Answer sheet]
The answer sheet 5 will be described with reference to FIG. Each answer sheet 5A, 5B,... (5) has a dot pattern (coded pattern) of the same pattern printed on substantially the entire surface thereof, and an attribute entry field for entering the affiliation (class) and name on the same. 501, answer columns (entry columns) 502 to 504 for entering answers to the questions "Question 1" to "Question 3" are printed. The dot pattern is printed with ink containing carbon that absorbs infrared rays, and the frame lines and characters in the columns 501 to 504 are printed with ink that does not absorb in the infrared region.

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

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

[Electronic pen]
Next, the electronic pen 1 will be described with reference to FIG. As shown in FIG. 5, 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 touches the answer tip 5 with the pen tip portion 103 of the electronic pen 1, and enters the affiliation (class) and name in the entry column 501. Or answering questions can be entered in the answer fields 502-504.

  The battery 112 is for supplying power to each component in the electronic pen 1. For example, the attachment / detachment of a cap (not shown) containing a 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 exceeding a predetermined value, the processor 108 Then, it is determined that the student has started entry, and the LED 105 and the CMOS camera 106 are operated.

  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 printed with the frame lines in each column has no absorptivity in the infrared region, the dot pattern can be easily recognized.

  While the student is writing, the processor 108 calculates the XY coordinates (coordinate data) on the answer sheet 5 of the stroke (one handwriting) to be written by the student from the dot pattern of the image data supplied by the CMOS camera 106. Calculate continuously. That is, the processor 108 converts the image data of the dot pattern supplied by the CMOS camera 106 into a data array, further converts it into an X coordinate bit value and a Y coordinate bit value, and then performs the data array by a predetermined calculation method. XY coordinate data and dot pattern address are calculated from the above. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, the pen pressure data, the dot pattern address, and the XY coordinate data. 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, the entered position is which of the answer sheets 5 Whether the position corresponds to the position can be specified by coordinate calculation by the processor 108.

  The memory 109 stores electronic pen identification information for identifying the electronic pen 1. If it is the electronic pen 1A, the electronic pen ID (electronic pen identification information) “pen01” is the electronic pen 1B, the electronic pen ID “pen02” is the electronic pen 1C, and the electronic pen ID “pen03” is the electronic pen 1C. Are stored in the memory 109.

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

  Each electronic pen 1 generates entry information each time a student enters an answer on the answer sheet 5 and transmits it to the aggregation device 3. For example, when the student touches the pen tip portion 103 of the electronic pen 1 on the answer sheet 5 (pen down) and fills in the attribute entry field 501 and answer fields 502 to 504, the electronic pen 1 is moved by the pressure sensor 107. A contact with the answer sheet 5 is detected when a writing pressure of a predetermined value or more is detected. A dot pattern is photographed by the CMOS camera 106 while irradiating infrared rays with the LED 105. The coordinate data and dot pattern address at the contact position on the answer sheet 5 are calculated by the processor 108 from the image data of the photographed dot pattern. The processor 108 generates entry information in which time information indicating the current time transmitted by the real-time clock 110, dot pattern address, coordinate data, writing pressure data, and electronic pen ID are associated with each other. The data is transmitted to the aggregation device 3.

  In this way, the electronic pen 1 generates entry information and transmits it to the aggregation device 3 while the student continues to fill in the answer sheet 5. Then, when the student removes the electronic pen 1 from the answer sheet 5 (pen up), the electronic pen 1 stops transmitting the entry information to the aggregation device 3.

When the student touches the pen tip 103 of the electronic pen 1 again with the answer sheet 5 (pen down) in order to enter the next stroke (Step 4), the electronic pen 1 performs the same process. The processor 108 calculates position coordinate data at the contact position on the answer sheet 5 from the image data of the imaged dot pattern, time information indicating the current time transmitted by the clock 110, dot pattern address, coordinate data, writing brush The entry information that associates the pressure data and the electronic pen ID is generated, and the entry information is transmitted to the aggregation device 3 by the communication unit 111 (Step 2). Thus, each time the stroke is entered by the student, each electronic pen 1 transmits entry information including the position coordinates along the stroke to the aggregation device 3.

  Here, when the electronic pen 1 transmits the entry information to the aggregation device 3 via the transfer device 2, after the electronic pen 1 transmits the entry information to the transfer device 2 wirelessly by the Bluetooth (registered trademark) system, The entry information received by the transfer device 2 is transmitted to the aggregation device 3 via the LAN by the TCP / IP communication method.

  In the aggregation device 3, when the entry information is received from the electronic pen 1 by the aggregation individual reception unit 33 or the aggregation transfer reception unit 34 and stored in the storage unit 301 (Step 5), the aggregation processing unit 31 converts the entry information into the electronic pen ID. And the user area of the position coordinate data included in the entry information is recognized with reference to the coordinate area of the user area stored in the storage unit 301 (Step 6). Based on the user area, the aggregation processing unit 31 recognizes whether the received entry information includes information entered in the attribute entry column 501 or any of the answer columns of the answer columns 502 to 504. Can do.

FIG. 9 is a diagram showing a screen for displaying the progress on the display unit 35 under the control of the aggregation processing unit 31. As shown in attribute entry field display areas 601 to 603 (600) of FIG. 9, the aggregation processing means 31 uses the information entered in the attribute entry field 501 of each answer sheet 5A to 5C as the frame line of the attribute entry field. It is displayed on the display means 35 so as to overlap with the image data.

  The list display means 36 displays the entry contents of the answer column in which the entry information currently received is written on the display means 35 in the area below the attribute entry field display areas 601 to 603. The display means 35 displays a list of the entry contents in the answer column currently entered. This will be described with reference to FIG. 7. When the list display means 36 recognizes the same user area as the user area recognized from the entry information received so far for each pen ID of each electronic pen 1 (Step 7). : No), below each attribute entry field display area 601 to 603 of the window, the answer line corresponding to the user area and the handwritten characters and symbols recognized by the entry information are displayed in each answer field. It is displayed on the display areas 701 to 703 (700) (Step 9).

  On the other hand, when the list display means 36 recognizes from the entry information a user area different from the user area recognized from the entry information received so far (Step 8: Yes), an answer column display corresponding to the electronic pen ID is displayed. The area 700 is switched (Step 8), and the answer line corresponding to the user area recognized from the current entry information and the handwritten characters, symbols, etc. recognized by the entry information in the answer field are displayed in each answer field. It is displayed in the areas 701 to 703 (Step 9).

  In order to display the same content as the display content displayed on the display unit 35 on the screen, the same display signal as the display signal to the display unit 35 is transmitted from the transmission unit 30 to the projector 4, and the projector 4 displays the display unit of the aggregation device 3. The same content is displayed on the screen in synchronism with 35 (Step 11). The switching of the answer column display during entry in the display means 35 (Step 5 to Step 9) is performed every time the entry information is received while the list display function is being executed (Step 10: Yes).

  FIG. 8 shows that in a certain exercise class, three students “Taro”, “Jiro”, and “Hanako” started answering using “electronic pen 1A”, “electronic pen 1B”, and “electronic pen 1C” for a certain period of time. It shows the answer entry status of each answer sheet 5A-5C when it has passed, "Taro" is answering question 3 question, "Jiro" is answering question 1 question, "Hanako" Is answering question 2. At this time, as shown in FIG. 9, the list display means 36 causes the answer column display area 701 to display the answer column of question 3 currently being answered among the entry information entered with the electronic pen 1A. The column display area 702 displays the answer column of question 1 currently being answered among the entry information entered with the electronic pen 1B, and the answer column display area 703 displays the entry information entered with the electronic pen 1B.

That is, the detailed entry status information display means 38 displays an answer time (entry time) to the answer column (user area) for each electronic pen 1, that is, for each student, in the progress details information fields 931 to 933 shown in FIG. The entry start time and entry end time are displayed. When updating, the background color of the column is changed and displayed so that the location being updated can be seen visually.

  The entry time measuring means 39 measures the answer time (entry time) for each answer column of the answer sheet 5. The answer time is obtained by (entry final time-entry start time-N-ML). N is the total of the time until the electronic pen 1 is pen-downed in the other answer field and the electronic pen 1 is pen-downed again in the target answer field. M is the total non-stroke time exceeding the set value (time when no stroke is written). L is the total time during which wireless communication is not established. The time N is the time when the electronic pen 1 is filled in the other answer fields, and the time M is not stroked by the electronic pen 1 and may not be considered to fill in the answer field. Since it is unclear whether the time is actually spent for an answer unless communication with the electronic pen 1 is established, these N, M, and L times are entered in the answer column. Since it is not considered to be the time devoted to, it is excluded by subtracting from the answer time. By measuring the answering time, it is possible to know the answering time required for the student to answer in each answering column and grasp the answering situation.

  FIG. 12 shows an example of calculating the answer time. This is an example of how to calculate the time to fill in the answer column for Question 3 when there is an entry in the answer column for Question 3 (User Area # 3) and the answer column for Question 2 (User Area # 2). is there. The non-stroke time detection threshold K is set to 60 seconds. The initial values of N, M, and L are set to 0. The entry time measuring means 39 stores the entry start time in the answer column for Question 3 and starts measuring the entry time. Then, while the entry to the answer column for Question 3 continues, the entry end time is updated and stored in real time. When the non-stroke time exceeds 60 seconds, the entry time measuring means 39 adds 60 to M and stores the time as a non-stroke measurement start time, and measures the non-stroke time until the next entry starts. When the answer column to be entered is changed to the answer column for Question 2, the entry time measuring means 39 measures the entry time in the answer column for Question 2. When the cap of the electronic pen 1 is closed and the entry is stopped, the entry time measuring means 39 starts measuring the non-communication time. When entry to the answer column for question 3 is resumed, the entry time measuring means 39 stores the entry end time while updating it in real time. When the “progress detail” display button 921 is clicked, the entry time measuring means 39 calculates the answer time. Note that the entry time measuring means may calculate the answer time in real time simultaneously with the storage of the entry end time.

  As described above, the entry time measuring means 39 accumulates the total stroke time in the answer column from the entry position and time of the electronic pen 1 and measures the answer time for each question of the student. The entry time measuring means 39 displays the answer status of each student on the screen in real time as a table. In addition, you may display with a graph etc. instead of a table | surface. With this feature, the instructor can analyze which questions the student is tripping over and which are averagely difficult based on the results of measuring the answer time for each question of the student, You can check the progress of each student's answer without moving through the classroom, so you can give guidance to many students at the same time. For example, for students who spend more than a certain time on one question, the answer status can be automatically displayed on the screen and individually taught.
