<First Embodiment>
First, a first embodiment according to the present invention will be described.

[Configuration of information processing system]
FIG. 1 shows a configuration of an information processing system according to the first embodiment. As shown in FIG. 1, the information processing system according to the first embodiment includes an electronic pen 1 used by a user, a computer device 2 that receives and processes entry information from the electronic pen 1, and a dot pattern (coding). Answer sheet 4 on which a pattern) is formed.

  The answer sheet 4 is printed with answer numbers and is provided with answer columns 41a to 41f (41) corresponding to the answer numbers. In the answer columns 41a to 41f, dot patterns having different coordinate ranges are formed. The dot pattern is printed with ink containing carbon that absorbs infrared rays. On the other hand, answer numbers, frame lines, and the like are printed with ink that does not absorb in the infrared region.

  The computer device 2 includes a processor such as a CPU, a memory such as a ROM and a RAM, a display, etc., and receives entry information from the electronic pen 1 and performs various processes. For example, the computer apparatus 2 includes a tablet PC having a capacitive touch panel. In one example, “iPad (registered trademark)” is used as the computer apparatus 2.

  In addition, the computer device 2 displays a screen about the electronic textbook (teaching material content) on the display. The electronic textbook is acquired by downloading from a server or installing from a CD. Hereinafter, the electronic textbook is also simply referred to as “textbook”.

  In FIG. 1, for convenience of explanation, only one answer sheet 4 is shown, but actually, a plurality of answer sheets 4 are prepared. In this case, a dot pattern having a different coordinate range may be formed on each of the plurality of answer sheets 4, or a dot pattern having the same coordinate range may be formed on the plurality of answer sheets 4. The answer sheet 4 is not limited to providing six answer fields 41.

[Dot pattern]
Next, an Anoto dot pattern (coded pattern) printed on the answer sheet 4 will be described with reference to FIGS. 2 and 3. FIG. 2 is a diagram illustrating the relationship between the dots of the dot pattern printed on the answer sheet 4 and the values to which the dots are converted. As shown in FIG. 2, 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 4 are determined by the combination of the information thus associated.

  FIG. 3A shows an arrangement of a certain dot pattern. As shown in FIG. 3A, 6 × 6 dots are arranged in a range of about 2 mm in length and breadth so that a unique pattern can be obtained no matter where 6 × 6 dots are taken from the answer sheet 4. Has been. The dot pattern formed by these 36 dots holds the position coordinates (for example, where the dot pattern is on the answer sheet 4). FIG. 3B is a diagram in which each dot shown in FIG. 3A is converted into a corresponding value based on the regularity shown in FIG. 2 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. FIG. 4 is a schematic diagram showing the structure of the electronic pen 1. 4, 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, and the user makes the pen tip portion 103 of the electronic pen 1 abut on the answer sheet 4 to enter a stroke (handwritten stroke) or the electronic pen 1. The pen tip portion 103 is brought into contact with the answer sheet 4 and tapped (tapping the answer sheet 4 by the pen tip portion 103). Here, contact of the pen tip portion 103 of the electronic pen 1 with the answer sheet 4 is referred to as pen-down, and removal of the pen tip portion 103 from the contacted (contacted) 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. Since the ink of the ink cartridge 104 does not include a material that absorbs infrared rays, the reading of the dot pattern by the processor 103 is not hindered.

  The battery 112 is for supplying electric power to each component in the electronic pen 1. For example, the battery 112 is configured to turn on / off the electronic pen 1 itself by attaching and detaching a cap (not shown) of the electronic pen 1. May be. 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 103 when the user writes or taps the answer sheet 4 or taps the answer sheet 4 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 or taps characters or the like on the answer sheet 4 with the electronic pen 1, the pen pressure is applied to the pen tip portion 103, and the processor 108 is detected when the pressure sensor 107 detects a writing pressure higher than a predetermined value. Determines that the user has started entry, and activates the LED 105 and the CMOS camera 106. Then, the communication unit 111 associates the pen-down information PD detected by the pressure sensor 107 with a pen ID described later, and transmits it to the computer apparatus 2 as entry information. When the user finishes entering one stroke and moves the electronic pen 1 away from the answer sheet 4, the pressure sensor 107 detects pen-up because no writing pressure exceeding a predetermined value is detected. Then, the communication unit 111 associates the pen-up information detected by the pressure sensor 107 with the pen ID, and transmits it to the computer apparatus 2 as entry information.

  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 answer sheet 4. The area is slightly shifted from the position where the pen tip portion 103 contacts the answer sheet 4. 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. Here, 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 photographing with the CMOS camera 106, a threshold value is provided based on the difference in the amount of reflected infrared light, so that a dot region containing carbon can be distinguished from other regions. Therefore, even if characters, frame lines, etc. are printed on the answer sheet 4, the printed ink does not absorb in the infrared region, so the processor 108 can recognize the dot pattern. 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. 3A, 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 (hereinafter simply referred to as “position”) on the answer sheet 4 of the stroke (handwriting) to be entered by the user from the dot pattern of the image data supplied by the CMOS camera 106 during the user's entry. The coordinates are also called “coordinates” or “coordinate information”). That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 3A supplied by the CMOS camera 106 into the data array shown in FIG. The data is converted into a Y coordinate bit value, and X and Y coordinate data are 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 this function is exhibited during the coordinate calculation. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, and X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. Since the 6 × 6 dot pattern in the answer sheet 4 does not overlap in the answer sheet 4, when the user enters characters or the like with the electronic pen 1, the entered position corresponds to any position on the answer sheet 4. This can be specified by 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, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits them to the computer apparatus 2 as entry information. Transmission to the computer apparatus 2 by the communication unit 111 is performed immediately and sequentially by wireless transmission such as Bluetooth (registered trademark). Here, one or a plurality of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the computer device 2 is stored as stroke information by the computer device 2. In other words, one stroke is made up of one or a plurality of X, Y coordinates (coordinate points), and the computer apparatus 2 can use one or a plurality of pieces constituting one stroke based on the pen-down information and the pen-up information. Recognize coordinate attribute information. As described above, a set of coordinate attribute information generated by the electronic pen 1 when the user enters one stroke is referred to as “stroke information”.

[Computer device]
Next, the computer apparatus 2 will be described. The computer device 2 includes, as hardware, an antenna device capable of data communication with the electronic pen 1, a processor such as a CPU, a memory such as ROM and RAM, a display, a personal computer including a mouse and a keyboard, and the like. . FIG. 5 is a functional block diagram of the computer apparatus 2. Functionally, the computer apparatus 2 includes an input unit 21, a communication unit 22, a processing unit 24, a storage unit 25, and a display unit 26.

  The input means 21 includes a mouse and a keyboard for inputting various commands and data. When the display unit 26 is a touch panel system, the touch panel provided on the display screen of the display unit 26 also functions as the input unit 21. The communication means (reception means) 22 is configured by an antenna reception circuit or the like, receives entry information from the electronic pen 1, and transmits it to the processing means 24. The display means 26 is constituted by a display or the like, and displays the contents instructed by the processing means 24.

  The storage means 25 is configured by a memory such as a hard disk, ROM, or RAM. The storage unit 25 stores coordinate definition information related to the coordinate range of the dot pattern printed on the answer sheet 4. Specifically, the memory | storage means 25 has memorize | stored the coordinate range of a different dot pattern allocated to each of the answer columns 41a-41f. The storage unit 25 stores electronic textbook data obtained by downloading from a server or installing from a CD.

  Further, the storage means 25 stores the entry information received from the electronic pen 1 for each pen ID according to the processing instruction of the processing means 24, and further secures a storage area according to the instruction of the processing means 24, and the pen down to the pen. The coordinate attribute information included in the entry information until the up is stored as stroke information for each pen ID. In addition to the above, the storage unit 25 stores various information generated by the execution of the program according to instructions from the processing unit 24.

  The processing means 24 is constituted by a processor such as a CPU and controls the entire computer apparatus 2. Specifically, the processing unit 24 includes a hole filling problem creating unit 241 and an answer matching unit 242.

  The hole filling problem creating unit 241 creates a hole filling problem by setting a character designated by the user using the input unit 21 with reference to a screen on which the contents of the textbook are displayed, in the hole filling portion. In this case, the hole filling problem creating unit 241 causes the display unit 26 to display the created hole filling problem. Specifically, the hole-filling problem creating unit 241 displays a plurality of characters designated by the user in blanks, and displays such blanks with question numbers. In addition, the filling-in-problem creation unit 241 sets all the same characters as the characters designated by the user in the range of the textbook for which the filling-in question is to be created, and the same for the filling-in place. Give the problem number. Then, the filling-in-problem creating unit 241 includes information that associates a plurality of filling-up places with characters set in each of the plurality of filling-up places (that is, characters set as filling-up problems), specifically a problem number and Information in which the correct answer is associated (hereinafter simply referred to as “correct answer information”) is created, and such correct answer information is stored in the storage means 25.

  The answering unit 242 answers the answer to the burying question created by the burying question creating unit 241 based on the entry information received by the communication unit 22 and corresponding to the entry on the answer sheet 4 by the electronic pen 1. Perform alignment. Specifically, the answer matching means 242 specifies the answer written on the answer sheet 4 by the user using the electronic pen 1 by character recognition, and based on the correct answer information stored in the storage means 25, the specified answer The answers are executed by comparing the correct answer with the correct answer. In this case, the answer matching unit 242 causes the display unit 26 to display a scoring symbol according to whether the answer is correct, a correct answer rate, and / or a score.

  After the answer matching means 242 executes the answer matching as described above, the hole filling question creating means 241 determines that the answer matching means 242 has determined that the answer is incorrect (not only the answer was incorrect but also the answer not found). A new filling problem is created in which the filling point is also included). In this case, the hole filling problem creating unit 241 newly assigns a problem number to the hole filling portion set as the new hole filling problem. Note that all the same characters as the filled characters are set as filled points, and the same problem numbers are assigned to the filled points, as described above.

  In the following, the mode set when creating a hole filling problem in the computer apparatus 2 is referred to as a “hole filling problem creating mode”, and the mode set when performing an exercise using the hole filling problem is referred to as a “problem exercise mode”. The mode set when answering the answers in the problem exercise mode is called “answer answering mode”. In addition, a mode that is set when the exercise is performed again using the newly created hole filling problem according to the result of the answer matching in the answer matching mode is referred to as a “re-challenge exercise mode”.

In this case, when the user selects the button A6 displayed as “answer matching” by clicking with the mouse or touching it with the touch panel, the answer matching means 242 executes the answer matching.

  In addition, a new filling question may be created according to the result of answering the answers to the new filling question. In other words, a new burying question may be created in which a portion determined to be an incorrect answer by the answer matching unit 242 is set as a burying portion. Thereby, it is possible to repeatedly create a hole filling problem until all the questions are correct. Therefore, the user can repeat the re-challenge until all questions are correct. Note that, according to an instruction from the user input means 21, the filling problem creating means 241 may add other characters to the filling problem.

[Effects of First Embodiment]
According to the first embodiment described above, the hole filling problem creating unit 241 can appropriately create a hole filling problem in which a character designated by the user is set in a hole filling part. Further, the hole filling problem creating means 241 can attach a problem number to the set hole filling portion. Thereby, the convenience of the hole filling problem can be improved. Specifically, by using the question number, it becomes possible to easily identify which question corresponds to the answer entered in the answer sheet 4. That is, it is possible to appropriately associate the problem set in the hole filling portion with the answer written in the answer sheet 4.

  Furthermore, in the first embodiment, the hole filling problem creating unit 241 can set all the same characters as the characters designated by the user in the hole filling area within the range of the textbook that is the target of creating the hole filling problem. . Thereby, when there are a plurality of characters that are the same as the characters designated by the user, it is possible to prevent the answer from being seen because only some of the characters are set in the hole-filled portion. In addition, the user's work for setting all of the same characters that should be filled in as filled holes can be omitted. Further, the hole filling problem creating means 241 can attach the same problem number to the same character as the character designated by the user. Thereby, all the same characters as the characters designated by the user can be automatically set as the same problem.

  Furthermore, in the first embodiment, the answer matching means 242 is based on the answer entered on the answer sheet 4 with the electronic pen 1, specifically, the answer identified by character recognition of the stroke entered with the electronic pen 1. Based on the above, it is possible to appropriately and automatically execute answering of answers to the hole filling problem. As a result, it is possible to save the user from having to manually answer.

  Furthermore, in the first embodiment, the hole-filling problem creating unit 241 can appropriately create a new hole-filling problem in which the part determined as an incorrect answer by the answer matching unit 242 is set as the hole-filling part.

Second Embodiment
Next, a second embodiment according to the present invention will be described. The second embodiment is different from the first embodiment in the structure of the answer sheet. Specifically, the answer sheet according to the second embodiment is not printed with the answer column 41 or the answer number like the answer sheet 4 according to the first embodiment.

  In the following, the configuration different from the first embodiment will be mainly described, and the description of the same configuration as the first embodiment will be omitted as appropriate. That is, functions and components that are not particularly described are the same as those in the first embodiment.

  FIG. 11 shows a configuration of an information processing system according to the second embodiment. As shown in FIG. 11, the information processing system according to the second embodiment is different from the information processing system according to the first embodiment in that it has an answer sheet 4 a instead of the answer sheet 4. The answer sheet 4a is not printed with the answer column 41 or the answer number like the answer sheet 4 according to the first embodiment, and the dot pattern (encoded pattern) is printed on almost the entire surface. The dot pattern is printed with ink containing carbon that absorbs infrared rays.

  In FIG. 11, for convenience of explanation, only one answer sheet 4a is shown, but actually, a plurality of answer sheets 4a are prepared. In this case, a dot pattern having a different coordinate range may be formed on each of the plurality of answer sheets 4a, or a dot pattern having the same coordinate range may be formed on the plurality of answer sheets 4a.

  FIG. 12 is a diagram for explaining a method of using the answer sheet 4a according to the second embodiment. As shown in FIG. 12, when the answer sheet 4 a is used, the user enters the answer number and the answer on the answer sheet 4 a using the electronic pen 1. In this case, the user need not enter the answers in the order of the answer numbers, and can enter the answers in the order of the known problems, for example. The answer thus entered is displayed on the display means 26 as described in [Problem Exercise Mode] (see FIG. 8). When the user finishes writing the answer on the answer sheet 4a and selects the button A4 shown in FIG. 8, the answer matching unit 242 executes answer matching.

  In the second embodiment, the answer matching unit 242 performs character recognition processing on the stroke entered on the answer sheet 4a with the electronic pen 1 based on the entry information from the electronic pen 1, thereby obtaining the answer number and the answer. Are identified, the identified answer number is associated with the answer, and then the answers are matched. In the example shown in FIG. 12, the answer matching unit 242 associates the answer number “2” with the answer “Peru”, associates the answer number “1” with the answer “1850”, and answers the answer number “3”. Correlate with Uraga.

  In one example, the answer matching unit 242 associates answer numbers and answers that have close stroke positional relationships. In another example, the answer matching unit 242 associates an answer number with an answer that is close to the entry time by the electronic pen 1 (which can be specified from the time information (time stamp) included in the entry information). In yet another example, the answer matching unit 242 associates an answer number with an answer that can be handled as being written on the same line of the answer sheet 4a. In this example, the answering unit 242 defines the y-axis in the vertical direction of the answer sheet 4a, and associates the answer number with the answer whose positions on the y-axis are approximately equal.

  After associating the answer number with the answer in this way, the answer matching unit 242 corresponds to the identified answer and the answer number associated with the answer based on the correct answer information stored in the storage unit 25. The answer is matched by comparing the correct answer of the question number.

  According to the second embodiment described above, even if the answer sheet 41 or the answer sheet 4a in which no answer number is formed is used, it is possible to match the answers by associating the entered answer with the answer number. It can be executed automatically and appropriately. Further, the user can freely enter the answer by using the answer sheet 4a in which the answer column 41 and the answer number are not formed. For example, the user can freely enter the answers in the order of the known problems, not in the order of the answer numbers.

  If the answer number is not entered in the answer sheet 4a, the answer matching means 242 answers in the order of the time and position of the stroke (or line by line) in order from the smallest question number. You can treat the answers as if they were filled out and perform an answer.
