Description

The present invention relates to a learning system (display system) using an electronic pen and a terminal device used therefor.

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

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

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

[System configuration of the learning system]
As shown in FIG. 1, the learning system (display system) 1 in this embodiment is an electronic pen 3A, 3B, 3C for each student to write an answer on an answer sheet 2A, 2B, 2C, (2). ,... (3), a terminal device 4 that receives entry information and the like from each electronic pen 3 and displays the entry content on a display (display means), and a projector that receives the display information from the terminal device 4 and displays it on the screen 6 7.

[Answer sheet]
On the answer sheets 2A, 2B, 2C,... (2) shown in FIG. 1, the same dot pattern (coded pattern) is printed, and the affiliation as shown in FIG. Affiliation entry field 11, name entry field 12 for entering name, answer fields "1" to "5" (reference numerals 13 to 17) corresponding to questions 1 to 5 and a call mark field indicating "HELP" 18 is printed. The dot pattern is printed with ink containing carbon that absorbs infrared rays. Moreover, each column 11-18 is printed with the normal ink which does not contain carbon.

[Dot pattern]
Next, a dot pattern (coded pattern) will be described. FIG. 3 is a diagram for explaining the relationship between the dots of the dot pattern printed on the answer sheet 2 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 2 are determined by the combination of 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 regardless of where 6 × 6 dots are taken on the answer sheet 2. ing. A dot pattern formed by these 36 dots holds position coordinates (for example, where the dot pattern is located on the answer sheet 2) and a dot pattern address (coded pattern address). 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. 3 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 3 that captures a dot pattern image.

[Electronic pen]
Next, the electronic pen 3 will be described. As shown in FIG. 5, the electronic pen 1 includes a processor 22 configured by a CPU, a memory 23 such as a ROM and a RAM, a data communication unit 24 configured by an antenna, a battery 26, and the like inside a housing 21. An LED 27, a CMOS camera 28, a clock 29, a pressure sensor 31, and an ink cartridge 32 are provided. The tip of the ink cartridge 32 is a pen tip portion 33, and each student puts the affiliation and name in the entry fields 11 and 12 while bringing the pen tip portion 33 of the electronic pen 3 into contact with the answer sheet 2. It is possible to fill in, answer the questions in the answer columns 13-17, or mark or tap the call mark column 18 (tap on the answer sheet 2 by the pen tip 33).

  The battery 26 is for supplying electric power to each component in the electronic pen 3, and is configured to turn on / off the power of the electronic pen 3 itself by, for example, detaching a cap (not shown) of the electronic pen 3. May be. The clock 29 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 22. The pressure sensor 31 detects the pressure applied through the ink cartridge 32 from the pen tip 33 when the student writes characters on the answer sheet 2 with the electronic pen 3, that is, the writing pressure, and transmits the value to the processor 22. To do.

  The processor 22 switches on / off the switches of the LED 27 and the camera 28 based on the writing pressure data supplied from the pressure sensor 32. That is, when a student writes characters or the like on the answer sheet 2 with the electronic pen 3, the pen tip 33 is applied with writing pressure, and when the pressure sensor 31 detects a writing pressure of a predetermined value or more, the processor 22. Determines that the student has started the entry and activates the LED 27 and the camera 28.

  The LED 27 and the CMOS camera 28 are attached in the vicinity of the pen tip portion 33 of the electronic pen 3, and an opening 34 is formed in a portion of the housing 21 that faces the LED 27 and the CMOS camera 28. The LED 27 illuminates infrared rays toward the vicinity of the pen tip portion 33 on the answer sheet 2. The region is slightly shifted from the position where the pen tip 33 contacts the answer sheet 2. The camera 28 captures a dot pattern in the area illuminated by the LED 27 and supplies image data of the dot pattern to the processor 22. Here, since carbon absorbs infrared rays, the infrared rays irradiated by the LED 27 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 taking a picture of the camera 28 and providing a threshold value based on the difference in the amount of reflected infrared light, it is possible to distinguish the dot area containing carbon from the other areas. Accordingly, since the ink printed in each of the columns 11 to 18 does not contain carbon, the processor 22 can recognize the dot pattern. Note that the shooting area by the camera 28 is a range including a size of about 2 mm × about 2 mm as shown in FIG. 4A, and the camera 28 takes about 50 to 100 shots per second.

  While the student's entry is made, the processor 22 uses the dot pattern of the image data supplied by the camera 28 to calculate the X and Y coordinates (simply “coordinate data” on the answer sheet 2 of the stroke (handwriting) to be entered by the student. Is also calculated continuously. That is, the processor 22 converts the image data of the dot pattern as shown in FIG. 4A supplied by the camera 28 into the data array shown in FIG. 4B, and further converts the X coordinate bit value · Y The data is converted into a coordinate bit value, and X, Y coordinate data and a dot pattern address are calculated from the data array by a predetermined calculation method. The processor 22 associates the current time (time stamp: entered time information) transmitted from the clock 29, the pen pressure data, the dot pattern address, and the X and Y coordinate data. Since the 6 × 6 dot pattern in the answer sheet 2 does not overlap in the answer sheet 2, when the student enters the answer contents with the electronic pen 3, the entered position is which of the answer sheets 2 Whether it corresponds to the position can be specified by coordinate calculation by the processor 22.

  In the memory 23, electronic pen identification information for identifying the electronic pen 3 is stored. If the electronic pen 3A is used, the electronic pen identification information "pen01" is used. If the electronic pen 3B is used, the electronic pen identification information "pen02" is used. In the case of the electronic pen 3C, electronic pen identification information “pen03” is stored in the memory 23, respectively.

  Then, the data communication unit 24 associates the electronic pen identification information, time information (time stamp), writing pressure data, dot pattern address, and X and Y coordinate data, and transmits them to the terminal device 4 as entry information. To do. Transmission by the data communication unit 24 is immediately and sequentially performed toward the terminal device 4 by Bluetooth (registered trademark) wireless transmission.

<Processing flow by learning system>
Next, the processing flow by the learning system 1 will be described with reference to FIG.

  As shown in FIG. 12, each electronic pen 3 </ b> A to 3 </ b> C generates entry information and transmits it to the terminal device 4 every time the student enters an answer on the answer sheets 2 </ b> A to 2 </ b> C. For example, when the student touches the pen tip 33 of the electronic pen 3A to the answer sheet 2A (pen down) (step S101) and fills in the affiliation entry field 11, the name entry field 12, and the answer fields 13-17, The electronic pen 3A detects contact with the answer sheet 2A when the pressure sensor 31 detects a writing pressure equal to or higher than a predetermined value. The electronic pen 3A captures a dot pattern with the camera 28 while irradiating infrared rays with the LED 27. Then, the coordinate data and the dot pattern address at the contact position on the answer sheet 2A are calculated from the image data of the captured dot pattern. Then, the processor 22 acquires time information indicating the current time transmitted by the clock 29, dot pattern address, coordinate data, and writing information associated with writing pressure data, and transmits the writing information to the terminal device 4 (step S102). ).

  In this way, the electronic pen 3A generates entry information and transmits it to the terminal device 4 while the student continues to fill in the answer sheet 2A. When the student removes the electronic pen 3A from the answer sheet 2A (pen up), the electronic pen 3A stops transmitting the entry information to the terminal device 4 (step S103). On the other hand, when receiving the entry information transmitted by the electronic pen 3A, the terminal device 4 displays the entry content on the display means (display) 44 in accordance with the coordinate data included in the entry information (step S104).

  Similar processing (steps S201 to S204) is also performed by answer entry on the answer sheet 2B by the electronic pen 3B, and similar processing (steps S301 to S304) is also performed by answer entry to the answer sheet 2C by the electronic pen 3C. Is done. The display on the screen 6 by the projector 7 is performed in synchronization with the display content on the terminal device 4 (step S401).

  At this time, if the display on the display means (display) 44 is “sheet display” (see FIG. 9), the processing means 43 fills in the answer sheet 2 filled in with the electronic pen identification number set as default and the answer sheet 2 When the instructor clicks either the electronic pen identification information displayed in the window area 52 or the list of user names with the mouse, the processing unit 43 displays the displayed content. Instead, the answer sheet 2 filled in with the electronic pen 3 having the clicked electronic pen identification information and the contents filled therein are displayed in the window area 51.

  On the other hand, if the display by the display means 44 is “display by question” (see FIG. 10), the processing means 43 displays an answer column corresponding to the same question number of a plurality of answer sheets 2 filled in with each electronic pen 3. Display at the same time. When the function button “next question” 55 or “previous question” 56 is clicked by the instructor with the mouse, the processing means 43 displays the next question number or the previous question number in each of the windows 61 to 63. Switch to the corresponding answer column to display. If the question number is input to the question number input field 57 by the instructor using the keyboard and the function button “display” 58 is clicked by the mouse, the processing means 43 corresponds to the question number input to the question number input field 57. Switch to the answer column to be displayed.

  In addition, FIG. 12 shows an example in which answers are continuously written on the answer sheet 2 by each electronic pen 3, but if answer entry by the electronic pen 3 is interrupted halfway, the electronic pen 3 causes the terminal device 4 to be interrupted. Transmission of entry information to will also be interrupted. If the processing means 43 of the terminal device 4 determines that the entry information from the electronic pen 3 has not been received, the unfilled time display area 76 is displayed on the window area corresponding to the electronic pen 3 and is not filled in. The continuous unfilled time is displayed in the time display area 76 every moment. Further, when the processing means 43 determines that the entry information from the specific electronic pen 3 has not been received for a predetermined time (for example, 10 minutes) or longer, the processing means 43 displays the display color of the unfilled time in the unfilled time display area 76. For example, the color is changed from blue to conspicuous red, or the entire corresponding window area is lit in red or the like. When the processing means 43 confirms the receipt of the entry information from the specific electronic pen 3, the processing means 43 hides the unfilled time display area 76 and stops lighting the window area if it is turned on.

  When the student marks or taps the call mark column 18 “HELP” (refer to FIG. 2) of the answer sheet 2 with the electronic pen 3, the electronic pen 3 sends the entry information in the call mark column 18 “HELP” to the terminal device 4. Transmit (steps S102, S202, S302). In the terminal device 4, when the processing means 43 recognizes the coordinate data in the call mark column 18 of the answer sheet 2 based on the entry information, the processing means 43 displays a call mark 73 that calls attention in the corresponding window area (reference diagram). 10). As a result, if the student puts a check mark in the call mark field 18 with the electronic pen 3, the call mark 73 is displayed in the window area corresponding to the electronic pen 3, and the instructor uses the electronic pen 3. Knowing that a particular student who has been called for a question etc. can go to that student.
