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

<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 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 dot patterns having different coordinate ranges. A plurality of notebook papers 4, a heading paper 5 for separating the notebook papers 4 by subject, and a multi-hole file 6 for binding the notebook paper 4 and the heading paper 5.

  The plurality of notebook sheets 4 correspond to so-called loose leaves, and the contents corresponding to the subject (for example, contents obtained by copying a board written in a lecture) are filled in with the electronic pen 1. On the plurality of notebook papers 4, dot patterns having different coordinate ranges (in other words, unique dot patterns) are formed. The dot pattern is printed with ink containing carbon that absorbs infrared rays. Further, the plurality of notebook papers 4 are formed with holes for binding by the multi-hole file 6. In this embodiment, the dot pattern is based on the Anoto method, but other coding patterns may be used.

  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 is “iPad (registered trademark)”.

  Here, a usage form of the information processing system as shown in FIG. 1 will be briefly described. The computer apparatus 2 displays on the display a time schedule table in which lecture subjects (categories) are associated with days of the week and time periods. The user refers to the timetable displayed in this way, and designates one subject from the plurality of subjects displayed in the timetable. At this time, the computer device 2 opens a file for a subject designated by the user. The file is for storing handwritten strokes entered on the note paper 4 by the user with the electronic pen 1 for each subject, and there are as many subjects as there are lectures. When the computer device 2 opened the file as described above, the handwritten stroke entered for the subject of the file was entered on a predetermined page of the notebook paper 4 (for example, the last page on which the handwritten stroke was entered). The handwritten stroke is displayed on the display. Further, the user enters a handwritten stroke on the notebook paper 4 with the electronic pen 1. At this time, the computer apparatus 2 draws the handwritten stroke entered by the user on the display, and stores the handwritten stroke in the file opened as described above.

[Dot pattern]
The Anoto dot pattern formed on the note paper 4 will be described with reference to FIGS. FIG. 2 is a diagram for explaining the relationship between the dots of the dot pattern formed on the notebook paper 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. 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 the notebook paper 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 width so that a unique pattern can be obtained no matter which part of the notebook paper 4 is taken 6 × 6 dots. ing. A dot pattern formed by these 36 dots holds position coordinates (for example, where the dot pattern is located on the note paper 4). 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 touches the pen tip portion 103 of the electronic pen 1 to the notebook paper 4 and enters a stroke (handwritten stroke). Here, contact of the pen tip portion 103 of the electronic pen 1 with the note paper 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 portion 103 when the user writes characters or marks on the notebook paper 4 with the electronic pen 1, that is, the writing pressure, and sends the value to the processor 108. To transmit.

  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 notebook paper 4 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 higher than a predetermined value, the processor 108 Is started, the LED 105 and the CMOS camera 106 are operated. 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 completes one stroke and moves the electronic pen 1 away from the notebook paper 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 notebook paper 4. The area is slightly deviated from the position where the pen tip 103 contacts the notebook paper 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 when characters, frame lines, and the like are printed on the note paper 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 notebook paper 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 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 on the notebook paper 4 does not overlap in the notebook paper 4, when the user enters characters or the like with the electronic pen 1, the entered position corresponds to any position on the notebook paper 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 unit 22 includes an antenna receiving circuit and the like, receives entry information from the electronic pen 1, and transmits it to the processing unit 24. The communication means 22 corresponds to an example of “reception means” in the present invention. 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 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, from pen down to pen up. Is stored as stroke information for each pen ID. Specifically, the storage unit 25 stores handwritten strokes written on the notebook paper 4 by the electronic pen 1 for each file corresponding to each of a plurality of subjects. In addition, the storage unit 25 stores various information generated by the execution of the program according to instructions from the processing unit 24. As an example of various types of information, the storage unit 25 stores coordinate definition information indicating the coordinate range of the dot pattern assigned to each of the plurality of notebook papers 4. Further, the storage means 25 stores data of a timetable in which subjects of lectures to be performed are associated with each day of the week and each time period.

  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 determination unit 241, a storage instruction unit 242, a display control unit 243, a notification unit 244, and an acquisition unit 245.

  The acquisition unit 245 of the processing unit 24 acquires a course designated by the user from among a plurality of courses displayed on the timetable by the display control unit 243 described later. Specifically, the acquisition unit 245 identifies the subject designated by the user using the input unit 21 based on the timetable data stored in the storage unit 25. For example, the acquisition unit 245 acquires the subject specified by the user clicking with the mouse or touch-inputting with the touch panel. Thus, the acquisition unit 245 corresponds to an example of “category acquisition unit” in the present invention.

  The determination unit 241 of the processing unit 24 determines whether a file corresponding to the subject acquired by the acquisition unit 245 is stored in the storage unit 25 when the user designates a subject. The determination unit 241 determines whether or not the file is opened when the user enters a handwritten stroke on the notebook paper 4 with the electronic pen 1. If the file is open, the determination unit 241 determines whether the file is a new file. Further, the determination unit 241 determines whether or not the notebook paper 4 on which a handwritten stroke is written by the electronic pen 1 is a new notebook paper 4. That is, the determination unit 241 determines whether the notebook paper 4 filled with the electronic pen 1 is the notebook paper 4 on which the handwritten stroke has already been written, or the notebook paper 4 on which the handwritten stroke has not yet been written. To do. In this case, the determination unit 241 refers to the coordinate definition information stored in the storage unit 25 (specifically, coordinate definition information indicating the coordinate range of the dot pattern assigned to the plurality of notebook papers 4). The notebook paper 4 in which the handwritten stroke is written is specified, and such a determination is made based on whether or not the data of the notebook paper 4 is included in a file stored by the save instruction unit 242 described later. In addition, the determination unit 241 determines whether or not the subject corresponding to the currently open file matches the subject corresponding to the note paper 4 on which the handwritten stroke is written.

  The storage instructing unit 242 of the processing unit 24 has acquired the handwriting stroke (specifically, the handwriting stroke corresponding to the entry information received by the communication unit 22) written on the notebook paper 4 by the electronic pen 1. It is stored in the storage means 25 as a file associated with the subject. Specifically, the save instruction unit 242 stores the handwritten stroke entered on the note paper 4 in the storage unit 25 in association with the page of the note paper 4. In this case, when it is determined by the determination means 241 that the handwriting stroke has been entered in the notebook paper 4 on which the handwriting stroke has already been entered, the storage instructing means 242 is newly entered on the page of the notebook paper 4. Overwrite handwritten strokes and store them. Specifically, the save instructing means 242 determines that the subject corresponding to the currently open file and the subject corresponding to the note paper 4 are different when the handwritten stroke is entered on the note paper 4 on which the handwritten stroke has already been entered. When it is determined by the determination unit 241 or when the determination unit 241 determines that the currently opened file is new, the handwritten stroke is stored in the subject file corresponding to the note paper 4. That is, the save instruction unit 242 stores the handwritten stroke in a subject file corresponding to the notebook paper 4, not in the subject of the currently open file.

  On the other hand, if the determination unit 241 determines that the handwritten stroke has been entered in the notebook paper 4 on which the handwritten stroke has not yet been entered, the save instruction unit 242 continues to the page stored in the currently opened file. Then, a new page corresponding to the note paper 4 is created, and the handwritten stroke is associated with the new page and stored in the storage unit 25. If the determination unit 241 determines that there is no file corresponding to the subject designated by the user, the save instruction unit 242 creates a new file associated with the subject.

  The display control means 243 of the processing means 24 causes the display means 26 to display a timetable associated with the subjects of the lectures to be performed for each day of the week and each time period. The display control unit 243 opens a file associated with the course acquired by the acquisition unit 245 when the user designates one course from the plurality of courses displayed in the timetable, and stores the file in the file. The stored handwritten stroke is displayed on the display means 26.

Further, when the handwritten stroke is entered on the notebook paper 4 with the electronic pen 1, the display control unit 243 displays the handwritten stroke on the display unit 26. Specifically, when it is determined by the determination unit 241 that the handwritten stroke has been entered in the notebook paper 4 on which the handwritten stroke has already been entered, the display control unit 243 stores the relevant file stored in the currently opened file. A page corresponding to the notebook paper 4 is displayed and a handwritten stroke is drawn on the page. Specifically, the display control unit 243 determines that the subject corresponding to the currently open file and the subject corresponding to the note paper 4 are different when the handwritten stroke is entered on the note paper 4 on which the handwritten stroke has already been entered. When it is determined by the determination means 241 or when the determination means 241 determines that the currently opened file is new, the file of the subject corresponding to the note paper 4 is opened and the note paper 4 is opened. A corresponding page is displayed and a handwritten stroke is drawn on the page. That is, the display control unit 243 causes the handwritten stroke to be drawn on the subject page corresponding to the notebook paper 4 instead of the subject of the currently open file.

  On the other hand, if the determination unit 241 determines that the handwritten stroke has been entered in the notebook paper 4 on which the handwritten stroke has not yet been entered, the display control unit 243 continues to the page stored in the currently opened file. A new page to be displayed is displayed, and a handwritten stroke is drawn on the page.

  The notifying means 244 of the processing means 24 is used when the determining means 241 determines that the file is not opened when a handwritten stroke is entered on the notebook paper 4 with the electronic pen 1 (that is, the user has not designated a subject). In other words, in other words, when the acquisition unit 245 has not acquired a subject), the user is notified that the subject has not been designated. In addition, when the determination unit 241 determines that the subject corresponding to the note paper 4 in which the handwritten stroke is written and the subject corresponding to the currently open file are different, the notification unit 244 notifies the user of that fact. To do. That is, the notification unit 244 notifies the user that the subject specified in the timetable is different from the subject corresponding to the note paper 4 on which the handwritten stroke is written.

  Here, when the user selects the file icon 11 by the input means 21, for example, when the user clicks the file icon 11 with the mouse or touch-inputs with the touch panel, the display control means 243 is stored in the selected file. The handwritten stroke is displayed on the display means 26. Specifically, the display control unit 243 causes the display unit 26 to display a predetermined page (for example, the last page) among the pages stored in the selected file.

[Processing flow]
Next, a processing flow according to the first embodiment will be described with reference to FIGS. 11 and 12.

  First, a processing flow performed when a subject is specified in the displayed timetable will be described with reference to FIG.

  First, the display control means 243 of the processing means 24 reads the time schedule table data stored in the storage means 25 and displays the time schedule table on the display means 26 (step S101). Then, the acquisition unit 245 of the processing unit 24 acquires the course designated by the user among the plurality of courses displayed on the timetable by the display control unit 243 (step S102). Specifically, the acquisition unit 245 identifies the subject designated by the user using the input unit 21 based on the timetable data stored in the storage unit 25. For example, the acquisition unit 245 acquires a subject specified by the user clicking with a mouse or detecting a touch input with a touch panel.

  Next, the determination unit 241 of the processing unit 24 determines whether there is a file corresponding to the subject acquired by the acquisition unit 245 (step S103). That is, the determination unit 241 determines whether or not a file corresponding to the subject is stored in the storage unit 25. If there is a file corresponding to the subject acquired by the acquisition unit 245 (step S103; Yes), the display control unit 243 opens the file associated with the subject and displays the handwritten stroke stored in the file. 26 (step S104). Specifically, the display control unit 243 causes the display unit 26 to display the last page among the pages stored in the file.

  On the other hand, when there is no file corresponding to the subject acquired by the acquisition unit 245 (step S103; No), the save instruction unit 242 of the processing unit 24 creates a file for the subject (step S105). Then, the save instruction unit 242 generates an icon for the created file and stores the file in a folder (lecture note folder) (step S106). Thereafter, the display control unit 243 opens the file created by the save instruction unit 242 (step S107). Specifically, the display control unit 243 causes the display unit 26 to display a blank page.

  Next, a processing flow performed when a handwritten stroke is entered on the notebook paper 4 with the electronic pen 1 will be described with reference to FIG. The processing flow shown in FIG. 12 is repeatedly executed every time entry information is generated by the electronic pen 1.

  First, when the user fills in the notebook paper 4 with the electronic pen 1, the electronic pen 1 transmits the generated entry information to the computer device 2. In the computer apparatus 2, when the communication means 22 receives the entry information transmitted from the electronic pen 1, the storage instruction means 242 of the processing means 24 stores the entry information in the storage means 25 (step S201).

  Next, the determination unit 241 of the processing unit 24 determines whether or not the file in which the handwritten stroke is stored is currently opened (step S202). In other words, the determination unit 241 determines whether the user has specified a subject, that is, whether the acquisition unit 245 has acquired a subject. When the file is not opened (step S202; No), the notification unit 244 of the processing unit 24 notifies the user that the subject is not designated (step S209). For example, the notification unit 244 displays a message indicating that a subject is not specified, a message indicating that a subject is to be specified, or the like as an image on the display unit 26 or outputs it as a sound from a speaker. Alternatively, the notification unit 244 outputs an alarm sound.

  On the other hand, when the file is open (step S202; Yes), the determination unit 241 determines whether or not the file is a new file (step S203). Specifically, the determination unit 241 determines whether or not the handwritten stroke is not yet stored in the currently opened file. When the file is not new (step S203; No), the determination unit 241 determines whether or not the notebook paper 4 on which the handwritten stroke is written by the electronic pen 1 is a new notebook paper 4 (step S204). Specifically, the determination unit 241 performs such determination based on whether or not the file stored in the storage unit 25 includes the data of the notebook paper 4 written with the electronic pen 1.

  When the notebook paper 4 filled in with the electronic pen 1 is not the new notebook paper 4 (step S204; No), the determination means 241 includes a course corresponding to the notebook paper 4 and a course corresponding to the currently opened file. Are matched (step S205). When the subject of the note paper 4 matches the subject of the file (step S205; Yes), the display control means 243 displays the page corresponding to the note paper 4 stored in the currently opened file, A handwritten stroke is drawn on the page (step S206). Further, the save instruction unit 242 stores the handwritten stroke in association with the page corresponding to the note paper 4.

  On the other hand, when the subject of the note paper 4 and the subject of the file do not match (step S205; No), the notification unit 244 notifies the user that the subject of the note paper 4 and the subject of the file do not match. (Step S207). That is, the notification unit 244 notifies the user that the subject specified in the timetable is different from the subject of the note paper 4 in which the handwritten stroke is written. For example, the notification unit 244 causes the display unit 26 to display a message indicating that the subject of the notebook paper 4 and the subject of the file do not coincide with each other, or output the message from the speaker. Alternatively, the notification unit 244 outputs an alarm sound.

  After performing the notification as described above, the display control means 243 opens the file of the subject corresponding to the note paper 4 in which the handwritten stroke is entered, and displays the page corresponding to the note paper 4 (step S208). . Then, the display control unit 243 draws a handwritten stroke on the displayed page, and the save instruction unit 242 stores the handwritten stroke in association with the page (step S206).

  On the other hand, when the note paper 4 written with the electronic pen 1 is a new note paper 4 (step S204; Yes), the display control means 243 draws a handwritten stroke on a new page (blank page). The save instruction unit 242 stores the handwritten stroke in association with the page (step S206). Specifically, the save instructing unit 242 creates a page for a new note paper 4 that is continuous with a page (specifically, the last page) stored in the currently opened file, and creates the created page as a file. Remember.

  On the other hand, when the file is new (step S203; Yes), the determination unit 241 determines whether or not the notebook paper 4 on which the handwritten stroke is written by the electronic pen 1 is a new notebook paper 4 ( Step S210). When the notebook paper 4 filled in with the electronic pen 1 is a new notebook paper 4 (step S210; Yes), the display control means 243 draws a handwritten stroke on a new page (blank page) and also stores it. The means 242 stores the handwritten stroke in association with the page (step S206). In this case, since the page is not stored in the currently opened file, that is, the new notebook paper 4 corresponds to the first page, the save instructing unit 242 continues to the page stored in the file. Create the first page without creating.

  On the other hand, when the note paper 4 entered with the electronic pen 1 is not the new note paper 4 (step S210; No), the display control means 243 displays the subject corresponding to the note paper 4 on which the handwritten stroke is entered. The file is opened and the page corresponding to the note paper 4 is displayed (step S208). Then, the display control unit 243 draws a handwritten stroke on the displayed page, and the save instruction unit 242 stores the handwritten stroke in association with the page (step S206).

[Effects of First Embodiment]

At the same time, such a handwritten stroke can be appropriately displayed for each subject. Specifically, handwritten strokes entered with the electronic pen 1 can be stored in association with the subject specified by the displayed timetable, and according to the subject specified by the displayed timetable. The handwritten stroke can be appropriately displayed. For example, when a handwritten stroke is entered on a new notebook paper 4, it becomes a matter of which subject the handwritten stroke is associated with and stored. However, according to the present embodiment, a new timetable is displayed by displaying a timetable. The handwritten strokes entered on the notebook paper 4 can be appropriately stored in association with the subject specified by the timetable.

[Modification of First Embodiment]
In the above, an example is shown in which a timetable in which a plurality of subjects are associated with a day of the week and a time period is displayed, but a plurality of subjects may be simply displayed instead of such a timetable. For example, a screen in which only a plurality of subject names are arranged can be displayed. By referring to such a screen, the user designates one subject from among the displayed subjects, and the computer device 2 performs the same processing as described above based on the subject designated by the user. It can be performed.
Moreover, in the said embodiment, the process means 24 attaches | subjects a page number for every page of each subject, and you may make it display the page number on each page. Further, the processing unit 24 may detect a finger operation by a touch panel provided on the display unit 26 and perform a page turning process.
