As shown in FIG. 1, an electronic pen input system includes an electronic pen 1 used by a student, a terminal device 3 having a display for allowing a student to view digitized data (electronic textbook) of a textbook, and a dot pattern. For printed books, class notes 4 for students to write notes, etc., workbooks 5 for each page of electronic textbooks printed, and electronic textbooks. A display (electronic blackboard) 6 that performs necessary display and a computer device 7 that is operated by a teacher and controls display on the display 6 are provided.

(Note for notebook)
First, the board writing notebook 4 will be described. A dot pattern (coded pattern) indicating position coordinates, which will be described later, is printed on the almost entire surface of the board writing notebook 4. The dot pattern is printed with an ink containing carbon that absorbs infrared rays so that the electronic pen 1 can read the dot pattern. A dot pattern indicating a different coordinate range is printed on each page of the board note 4. The board note 4 is an example of the “note” in the present invention.

(workbook)
Next, the workbook 5 will be described. Workbook 5 is a teaching material that contains exercises for electronic textbooks, etc. Each page contains questions related to the contents of a predetermined page of the electronic textbook, the predetermined page of the electronic textbook, the answer to the problem, etc. There are provided a writing area 50 for writing, a textbook opening area 51 displayed as "Open textbook", and a board writing opening area 52 displayed as "Open textbook". When solving a problem, students can refer to the electronic textbook page listed on the problem page. The textbook opening area 51 is an operation area tapped by the electronic pen 1 when displaying a page of the electronic textbook corresponding to the page of the workbook 5 provided with the textbook opening area 51 on the terminal device 3. This will be described later with reference to FIG. The board writing open area 52 is used when the terminal device 3 displays a page of the board writing notebook 4 in which a note of the electronic textbook page corresponding to the page of the workbook 5 provided with the board writing opening area 52 is displayed. The operation area tapped by the electronic pen 1. This will be described later with reference to FIG. The textbook opening area 51 is an example of the “learning material display operation area” in the present invention, and the board writing opening area 52 is an example of the “notebook display operation area” in the present invention.

  Also, a dot pattern is printed in the writing area 50, the textbook opening area 51, and the board writing opening area 52 of each page of the workbook 5. The dot pattern is printed with an ink containing carbon that absorbs infrared rays so that the electronic pen 1 can read the dot pattern. In this case, a dot pattern indicating a different coordinate range is printed in each area of each page of the workbook 5. In addition, characters, symbols, and the like printed on the workbook 5 are printed with ink that does not absorb in the infrared region so as not to alienate the reading of the dot pattern by the electronic pen 1. The workbook 5 is an example of the “auxiliary teaching material” in the present invention.

(Dot pattern)
Next, a dot pattern (coded pattern) composed of dots will be described with reference to FIGS. The dot pattern is based on the system of Anoto. FIG. 2 is a diagram for explaining the relationship between dots of a dot pattern and 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. That is, 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 virtual 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 each page of the board writing notebook 4 and each page of the workbook 5 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 within a range of about 2 mm in length and width are obtained by taking 6 × 6 dots from any part on each page of the notebook 4 and each page of the workbook 5. Also arranged to be a unique pattern. The dot pattern formed by these 36 dots holds the position coordinates (for example, where the dot pattern is on each page of the board note 4 and each page of the workbook 5). FIG. 3B is a diagram in which each dot shown in FIG. 3A is converted into a value associated with 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 brings the pen tip portion 103 of the electronic pen 1 into contact with the page of the notebook 4 for writing or the page of the workbook 5 and strokes (handwriting strokes). ) The ink of the ink cartridge 104 does not contain an infrared absorbing material (such as carbon) so as not to hinder reading of the dot pattern. Here, the first contact of the pen tip portion 103 of the electronic pen 1 with the page of the notebook 4 for writing or the page of the workbook 5 is called pen down, and the pen tip portion 103 is brought into contact with the pen tip portion 103 from the state of contact (contact). Is called 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.

  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 is a 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 page of the notebook 4 or the page of the workbook 5 with the electronic pen 1. The writing pressure is detected and the value is transmitted 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 characters or the like on the page of the notebook 4 or the workbook 5 with the electronic pen 1, the pen pressure is applied to the pen tip 103, and the pressure sensor 107 detects a writing pressure higher than a predetermined value. The processor 108 determines that the user has begun to fill 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 identification information (hereinafter referred to as “pen ID”) of the electronic pen 1 to be described later, and transmits the information to the terminal device 3 as entry information. To do. When the user finishes writing one stroke and moves the electronic pen 1 away from the page of the notebook 4 or the page of the workbook 5, the pressure sensor 107 does not detect a writing pressure higher than a predetermined value, and the pen ups. 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 terminal device 3 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 page of the notebook 4 for writing or the page of the workbook 5. The region is slightly deviated from the position where the pen tip 103 contacts the page of the notebook 4 or the page of the workbook 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. 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.

  While the user performs the entry, the processor 108 uses the dot pattern of the image data supplied by the CMOS camera 106 to determine the X on each page of the board note 4 or the workbook 5 of the stroke (handwriting) to be entered by the user. , Y coordinates (hereinafter simply referred to as “coordinate data” or “coordinate information”) are continuously calculated. 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”. The 6 × 6 dot pattern on each page of the board writing notebook 4 or each page of the work book 5 does not overlap in all pages of the board writing notebook 4 and all pages of the work book 5. When a character or the like is entered with the electronic pen 1, it can be specified by coordinate calculation by the processor 108 which position in the page of the notebook 4 for writing or the position of each page of the workbook 5 corresponds.

  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 terminal device 3 as entry information. Transmission to the terminal device 3 by the communication unit 111 is performed instantaneously 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 terminal device 3 is stored as stroke information by the terminal device 3.
