The handwriting input device discriminates first input means whose area of the portion pressing the touch panel is relatively small and second input means whose area of the portion pressing the touch panel is relatively large on the basis of the signal output from the touch panel, and determines that the input operation is a page turn operation when a touch position of the second input means detects an input operation moving to a side of the fixed end side of the blank sheet, and includes a control unit for storing, as handwritten data of one page, a moving trajectory of the touch position of the first input means until the page turn operation is detected.

Description

  The present invention relates to a handwriting input device and a control program, and more particularly to a handwriting input device that converts information handwritten on paper into electronic data and a control program that operates on the handwriting input device.

  2. Description of the Related Art In recent years, handwritten input devices having a function of storing information (referred to as handwritten information) such as characters and figures handwritten on paper as electronic data have been sold. This handwriting input device is equipped with a pressure-sensitive touch panel. When handwriting is performed on a sheet fixed on the touch panel with a pen or the like, the touch panel detects the pressure of the pen, and the movement locus of the touch position is used as electronic data (handwritten data). Can be remembered.

  In such a handwriting input device, it is necessary to detect that a page (paper) has been turned in order to distinguish between handwritten information handwritten on a certain page (paper) and handwritten information handwritten on the next page (paper). There is. Therefore, conventionally, when a user presses a button (page feed button or the like) provided in advance in the handwriting input device or performs a predetermined pen operation on the touch panel, the handwriting input device performs the button pressing or pen Recognizing the operation, it was detected that the page was turned.

  There has also been proposed a method in which a handwriting input device automatically detects that a page has been turned. For example, in the following Patent Document 1, two switches A and B are provided in front of the inner surface of the left side wall, and it is detected that the page has been turned by detecting ON / OFF of the two switches. . In Patent Document 2 below, a mark is previously placed on a diagnostic sheet, and the mark is read by a sensor to recognize the page. In Patent Document 3 below, it is detected that a page has been turned by detecting a hole or mark in the paper.

JP 2002-009988 A Japanese Patent Laid-Open No. 10-2111173 JP-A-10-254610

  However, in the above prior art, special paper (such as paper with a special mark or mark printed or paper with a hole) is used to detect when a page is turned, or handwritten input. The page turns because the device is equipped with special components (page feed buttons, sensors for detecting the above marks, marks, holes, etc.) and allows the user to perform special operations (such as predetermined pen operations) There was a problem that it was not possible to detect easily.

  The present invention has been made in view of the above problems, and its main purpose is that pages are turned by natural operation without requiring special paper, special components, or special operations. An object of the present invention is to provide a handwriting input device and a control program that can easily detect the above.

  One aspect of the present invention is a handwriting input device that includes a touch panel that can detect a press from above a sheet, and one side of the sheet is fixed on the touch panel, and is based on a signal output from the touch panel. A first input unit having a relatively small area for pressing the touch panel, and a second input unit having a relatively large area for pressing the touch panel; When the touch position of the means detects an input operation that moves toward the side of the fixed end of the paper, it is determined that the input operation is a page turning operation, and the page turning operation is detected until the page turning operation is detected. The moving part of the touch position of a 1st input means is provided with the control part which preserve | saves as one page of handwritten data, It is characterized by the above-mentioned.

  Another aspect of the present invention is a control program that includes a touch panel that can detect a press from above a sheet, and that operates on a handwriting input device in which one side of the sheet is fixed on the touch panel. Based on a signal output from the touch panel to the device, a first input means having a relatively small area for pressing the touch panel and a second area having a relatively large area for pressing the touch panel A first process for discriminating between the input means and the input operation when the touch position of the second input means detects an input operation that moves toward the side of the fixed end of the paper. Second processing for determining that the first page is turned, and the movement locus of the touch position of the first input unit until the page turning operation is detected is stored as handwritten data for one page. Third processing that is characterized in that to the execution.

  According to the handwriting input device and the control program of the present invention, it is possible to easily detect that a page has been turned by a natural operation without requiring a special sheet, a special component, or a special operation.

  The reason is that the handwriting input device (control program) includes a first input means such as a pen for handwriting input and a second input means such as a finger having a larger area for pressing the touch panel than the first input means. And the second input unit determines that the operation by the second input unit is a page turning operation when the touch position of the second input unit detects an operation of moving toward the side of the fixed end of the sheet. This is because the control for saving the handwritten information by the first input means until the page turning operation is detected as handwritten data for one page is performed.

  As shown in the background art, when storing handwritten information on paper as electronic data using a handwriting input device having a pressure-sensitive touch panel, the information handwritten on each page can be distinguished for each page. In order to do this, it is necessary to detect that the page has been turned. Therefore, conventionally, the handwriting input device detects that the page has been turned when the user presses a button provided in advance or performs a special pen operation. In addition, a switch was provided on the inner surface of the side wall of the housing, and it was detected that the page was turned by turning the switch ON / OFF, or the page was turned by reading a mark, mark or hole on the paper with a sensor. It was detected.

  However, in the method of providing buttons and switches for instructing / detecting page turning in the handwriting input device, the configuration and control of the handwriting input device are complicated. Further, in the method of providing a sensor for reading marks, marks, holes, etc. in the handwriting input device, the configuration and control of the handwriting input device are complicated, and special paper is required. Moreover, in the method of requesting a special pen operation from the user, the user operation becomes complicated, and the thought when inputting handwritten information stops. As described above, the conventional method has a problem that it is not possible to easily detect that the page is turned.

  Therefore, in one embodiment of the present invention, a page turning operation can be detected based on a change in touch position or a change in touch pressure that occurs during an actual page turning operation. Specifically, the first input means such as a pen for handwriting input and the second input means such as a finger having a larger area for pressing the touch panel than the first input means can be identified. In the apparatus, when an operation in which the touch position of the second input unit moves toward the fixed end side of the sheet is detected, it is determined that the operation by the second input unit is a page turning operation, and the page turning is performed. Handwritten information by the first input means until an operation is detected is stored as handwritten data for one page.

  This makes it easy to detect that a page has been turned by a natural operation without using special paper, providing a special component in the handwriting input device, or requiring the user to perform a special operation. be able to.

  In order to describe the above-described embodiment of the present invention in more detail, a handwriting input device and a control program according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating an external configuration of a handwriting input device according to the present embodiment, and FIG. 2 is a diagram illustrating an input method of the handwriting input device. FIG. 3 is a block diagram showing the configuration of the handwriting input device of this embodiment, and FIG. 4 is a flowchart showing the operation of the handwriting input device. 5 to 10 are diagrams illustrating an example of a page turning operation, and FIGS. 11 and 12 are diagrams illustrating an example of a usage pattern of the handwriting input device. FIG. 13 is a diagram illustrating a page turning operation notification method in the handwriting input device according to the present embodiment.

  As shown in FIG. 1, the handwriting input device 10 according to the present embodiment is a device that includes a pressure-sensitive touch panel and performs handwriting input on one or a plurality of sheets placed on the touch panel. As shown in FIG. 2A, the handwriting input device 10 includes a handwriting input using a writing tool (first input means) such as a pen, and a first input as shown in FIG. An operation using a finger or the like (second input means) having a larger area of a portion that presses the touch panel than the means (second input means) can be discriminated by the touch area or the touch pressure.

  Although the size of the handwriting input device 10 is arbitrary, the small one is a jogger size (business card size), and the large one is about A3. The housing of the handwriting input device 10 may be provided with a holding unit such as a clip for simply fixing the paper on the touch panel.

  As shown in FIG. 3, the handwriting input device 10 includes a control unit 11, a communication I / F unit 12, a touch panel control unit 13, a touch panel 14, and the like.

  The control unit 11 includes a CPU (Central Processing Unit) 11a and a memory such as a ROM (Flash ROM) 11b, a RAM (Random Access Memory) 11c, and an SD (Secure Digital) card 11d. The CPU 11a stores the data in the ROM 11b. The program is developed on the RAM 11c and executed, and the entire handwriting input device 10 is controlled. The RAM 11 c also functions as an input buffer that stores handwritten information (movement trajectory) input by handwriting on the touch panel 14. When the touch panel control unit 13 detects a page turning operation described later, the CPU 11a reads the handwritten information stored in the RAM 11c, saves it as the handwritten data for one page in the SD card 11d, and erases the handwritten information in the RAM 11c. To do.

  The communication I / F unit 12 is a NIC (Network Interface Card), a modem, NFC (Near Field Communication), Bluetooth (registered trademark), Transferjet, or the like, and a server that stores handwritten data, a terminal that displays handwritten data, and the like Enables communication.

  The touch panel control unit 13 acquires a signal output from the touch panel 14 and inputs with a pen (first input means) based on the coordinates (touch position) and the pressing force (touch pressure) at which the touch panel 14 detects pressing. It is determined whether the operation is an operation or an input operation with a finger (second input means). If an input operation with a finger (second input means) is detected, the touch position of the finger may be an operation of moving toward the side of the sheet fixing side (hereinafter referred to as the fixed end side). In this case, the page turning operation is determined. When an input operation with two fingers is detected, the first touch position on the side opposite to the fixed end side (hereinafter referred to as the release end side) approaches the second touch position on the fixed end side ( That is, if the first touch position is an operation that moves toward the side of the fixed end), it is determined that the operation is a page turning operation. In addition, if the first touch position on the release end side and the second touch position on the fixed end side approach each other (that is, the first touch position moves toward the side on the fixed end side), Judged as a page turning operation.

  The touch panel 14 includes a table on which a sheet is placed and a pressure-sensitive touch sensor in which electrodes are arranged in a grid on the surface of the table, and the touch sensor is configured to be able to detect touches at a plurality of locations. Then, pressing by a pen or a finger from above the paper is detected, and the touch position and touch pressure are notified to the touch panel control unit 13. The touch panel 14 only needs to be able to detect a press by a pen or a finger, and may be configured only by a pressure-sensitive touch sensor, or an electromagnetic touch sensor that detects the magnetism of a magnet embedded in the pen. May be combined.

  In this embodiment, the touch panel control unit 13 discriminates between an input operation using a pen (first input means) and an input operation using a finger (second input means), and using a finger (second input means). Although it is configured to determine whether the input operation is a page turning operation, this process may be configured to be executed by a program (control program) operating on the control unit 11.

  Hereinafter, the operation of the handwriting input device 10 having the above configuration will be described with reference to the flowchart of FIG.

  First, when a user touches a desired position on the touch panel 14 using a writing tool (first input means) or a finger (second input means) such as a pen, the touch panel 14 detects the touch, The touch pressure is notified to the touch panel control unit 13. The touch panel control unit 13 determines whether a touch other than the writing instrument has been detected by comparing the touch area or the touch pressure with a predetermined threshold (S101).

  When the touch panel control unit 13 detects a touch of a writing instrument such as a pen (a touch whose touch area is equal to or smaller than a predetermined first threshold, or a touch whose touch pressure is equal to or larger than a predetermined second threshold), The control unit 11 determines that the user's input operation is an input operation of handwritten information, and stores the movement locus of the touch position in an input buffer (such as the RAM 11c). Then, returning to S101, the touch panel control unit 13 monitors a touch other than the writing instrument.

  On the other hand, when the touch panel control unit 13 detects a touch other than a writing instrument such as a pen (a touch whose touch area is larger than the first threshold or a touch whose touch pressure is smaller than the second threshold), It is determined whether or not the touch is (S102). Note that when a touch other than the writing tool is detected in S101, it may not be immediately determined that the touch is a finger touch, for example, when a hand holding a writing tool such as a pen touches the touch panel 14. Because.

  When the touch panel control unit 13 determines that the touch is not a finger touch (for example, the touch area is larger than a predetermined third threshold (third threshold> first threshold), or the touch pressure is determined in advance. If the determined fourth threshold value is smaller than the fourth threshold value (fourth threshold value <second threshold value), it is determined that the user's input operation is neither an input operation of handwritten information nor a page turning operation. Monitor touches other than.

  On the other hand, when determining that the touch is a finger touch, the touch panel control unit 13 determines whether the user input operation is a page turning operation based on FIGS. 5 to 12 (S103). A method for determining whether or not this page turning operation will be described later.

  When the touch panel control unit 13 determines that the user input operation is not a page turning operation, the control unit 11 stores the movement locus of the touch position as handwritten information in an input buffer (such as the RAM 11c). Then, returning to S101, the touch panel control unit 13 monitors a touch other than the writing instrument.

  On the other hand, when the touch panel control unit 13 determines that the user's input operation is a page turning operation, the control unit 11 reads out a series of handwritten information stored in the input buffer (such as the RAM 11c) and outputs the series of handwritten information. The handwritten data of the page is saved in the SD card 11d or the like (S104), and then a series of handwritten information stored in the input buffer (RAM 11c or the like) is deleted (S105).

  Next, the control unit 11 determines whether or not it is set to feed back to the user that the page turning operation has been performed (S106). If it is not set to feed back, the process returns to S101, The touch panel control unit 13 monitors a touch other than the writing instrument. On the other hand, if it is set to feed back, the control unit 11 notifies the user that a page turning operation has been detected (S107).

  As this notification method, for example, the handwriting input device 10 is provided with sounding means such as a speaker, and as shown in FIG. 13A, the user is notified that a page turning operation has been performed with a buzzer or voice. Can do. Further, the handwriting input device 10 is provided with vibration means such as a vibrator, and as shown in FIG. 13B, the user can be notified that the page turning operation has been performed by vibrating the handwriting input device 10. . The handwriting input device 10 may be provided with light emitting means such as an LED (Light Emitting Diode), and the user can be notified that the page turning operation has been performed by turning on / flashing the light emitting means. Thus, by feeding back to the user that the page turning operation has been performed by sound, vibration, light, or the like, the handwritten data can be stored as intended by the user.

  A method for determining whether or not the user's input operation is a page turning operation will be described below with reference to FIGS.

  FIG. 5 shows an example of a page turning operation. When actually turning the page, first, as shown in FIG. 5A, place the thumb on the release end side of the paper on the touch panel 14 (for example, in the vicinity of the lower left corner of the paper in the case of the right hand). One other finger (here, the index finger) is placed near the center of the paper (fixed end side) with respect to the thumb. Next, as shown in FIG. 5B, the position of the index finger is fixed, the thumb is moved closer to the index finger, and the edge of the paper is turned up. Then, as shown in FIG. 5C, the thumb is moved to the position of the index finger, and the turned up paper is pinched with the thumb and the index finger.

  In the case of this operation, the index finger serving as the fulcrum of the operation strongly presses the touch panel 14 when turning up the edge of the paper, so that the touch pressure of the index finger changes as shown in FIG. Accordingly, the touch panel control unit 13 detects a finger touch at two points on the release end side of the sheet of the touch panel 14, and the touch position of the finger on the release end side approaches the touch position of the finger on the fixed end side (that is, the sheet In this case, it can be determined that the user's input operation is a page turning operation. In particular, the touch position of the finger on the release end side approaches the touch position of the finger on the fixed end side, and the touch pressure of the finger on the fixed end side increases with the movement of the touch position of the finger on the release end side. If it has changed, it can be reliably determined that the user's input operation is a page turning operation.

  FIG. 6 shows another example of the page turning operation. When actually turning the page, first, as shown in FIG. 6A, place the thumb on the release end side of the paper on the touch panel 14 (for example, in the vicinity of the lower left corner of the paper in the case of the right hand). One other finger (here, the index finger) is placed near the center of the paper (fixed end side) with respect to the thumb. Next, as shown in FIG. 6B, the edge of the paper is turned up by moving the thumb and index finger closer to each other. Then, as shown in FIG. 6C, the rolled up paper is pinched with the thumb and index finger.

  In the case of this operation, the thumb and the index finger move so as to approach each other, so that the locus of the touch position of the two fingers changes as shown in FIG. Accordingly, the touch panel control unit 13 detects a finger touch at two points on the release end side of the sheet of the touch panel 14, and the movement locus of the touch position of the two points is as shown in FIG. 6D (release end). The touch position of the finger on the side moves toward the side on the fixed end side of the paper, and the touch position of the finger on the fixed end side moves toward the side on the release end side of the paper) It can be determined that this is a page turning operation.

  FIGS. 5 and 6 show a case where the release end side of the paper (here, the lower left corner) is turned up with the right hand. For example, the handwriting input device 10 is placed on a desk or knee and the dominant hand (right hand and In some cases, a page turning operation with a finger is performed with the opposite hand (left hand) while performing a handwriting input operation with a pen.

  Also in this case, as shown in FIG. 7, when the touch position of the finger on the release end side approaches the touch position of the finger on the fixed end side (see FIGS. 7A to 7C), the user input operation is performed on the page. It can be determined that this is a turning operation. In particular, the touch position of the finger on the release end side approaches the touch position of the finger on the fixed end side, and the touch pressure of the finger on the fixed end side increases with the movement of the touch position of the finger on the release end side. If it has changed, it can be reliably determined that the user's input operation is a page turning operation. Also, as shown in FIG. 8, the touch position of the finger on the release end side and the touch position of the finger on the fixed end side approach each other (see FIGS. 8 (a) to 8 (c)), and the movement locus thereof is shown in FIG. ), It can be determined that the user's input operation is a page turning operation.

  5 to 8 illustrate the case where the page turning operation is performed using two fingers, but the page turning operation may be performed using one finger. For example, when the upper side of the paper is fixed to the touch panel 14 by the holding unit, first, as shown in FIG. 9A, at least one finger (here, the index finger) is used as the release end of the paper. On the side (in this case, the bottom of the paper). Next, as shown in FIG. 9B, the index finger is moved so as to approach the side on the fixed end side of the sheet (in this case, the upper side of the sheet) to bend the sheet. Then, as shown in FIG. 9C, the page can be turned by moving the index finger to the side on the fixed end side of the paper and flipping up the paper.

  In this operation, the index finger moves from the release end side (lower part) of the sheet toward the fixed end side (upper part) in a direction substantially perpendicular to the side on the release end side. Accordingly, the touch panel control unit 13 detects a finger touch on the paper release end side of the touch panel 14, and the touch position moves toward the fixed end side in a direction substantially perpendicular to the side on the release end side. In this case, it can be determined that the user's input operation is a page turning operation. At that time, it is not necessary to move the touch position to the top of the sheet.

  Although FIG. 9 illustrates the case where the upper side of the paper is fixed by the holding portion, the touch position is also the release end side of the paper (for example, the left edge) even when the right or left side of the paper is fixed. Part) toward the fixed end (for example, the right end) along a direction substantially perpendicular to the side on the release end side, it can be determined that the user's input operation is a page turning operation. .

  In FIG. 9, it is determined that the touch position is a page turning operation when the touch position moves from the release end side of the paper toward the fixed end side in a direction substantially orthogonal to the side of the release end side. The touch position is not necessarily moved along a direction substantially orthogonal to the side on the release end side.

  For example, as shown in FIG. 10A, when the upper side of the sheet is fixed to the touch panel 14 by the holding unit, a finger is placed on the corner (here, the lower left corner) on the release end side of the sheet. As shown in FIGS. 10B and 10C, even if the finger is moved obliquely upward (here, diagonally upward to the right), the sheet can be curved and flipped up. Accordingly, when the touch panel control unit 13 detects a finger touch on the release end side of the touch panel 14 and the touch position moves in a direction approaching the fixed end side of the paper, the user input operation is a page turning operation. It can be judged.

  5 to 10 describe the case where the paper is fixed by the holding unit. However, when the handwriting input device 10 is held by one hand and is operated by the finger of the other hand, the handwriting input device 10 is used. The paper can also be held by the hand holding the paper.

  For example, as shown in FIGS. 11 (a) and 11 (b), the handwriting input device 10 is placed on the left arm, and the upper hand (right side portion) of the handwriting input device 10 is held with the left hand, while the pen is held with the right hand finger or the right hand. When the handwriting operation is performed, the paper is strongly held by the upper part (right side part) of the handwriting input device 10 with the left hand. Accordingly, the touch panel control unit 13 detects a finger touch at the end of the touch panel 14, and when the touch position does not change and the touch pressure exceeds a predetermined threshold, the side on which the touch is detected is the fixed end side of the sheet. After that, the touch of the finger is further detected on the release end side of the paper, and the touch position moves toward the fixed end side in a direction substantially perpendicular to the side on the release end side. It can be determined that the user's input operation is a page turning operation.

  In addition, as shown in FIG. 12, when a handwriting operation is performed with the finger of the right hand or a pen held in the right hand while holding the left side of the handwriting input device 10 with the left hand, the paper is placed on the left side of the handwriting input device 10 with the left hand. Strongly held. Accordingly, the touch panel control unit 13 detects a finger touch at the end of the touch panel 14, and when the touch position does not change and the touch pressure exceeds a predetermined threshold, the side on which the touch is detected is the fixed end side of the sheet. After that, the touch of the finger is further detected on the release end side of the paper, and the touch position moves toward the fixed end side in a direction substantially perpendicular to the side on the release end side. It can be determined that the user's input operation is a page turning operation.

  Here, a form in which the handwriting input device 10 is placed on the left arm and the upper part (right side part) of the handwriting input apparatus 10 is suppressed with the left hand, and a form in which the left side part of the handwriting input device 10 is suppressed with the left hand and used. However, the usage pattern of the handwriting input device 10 is not limited to that illustrated in FIGS. 12 and 13. For example, the handwriting input device 10 may be used while suppressing the lower portion of the handwriting input device 10 with the left hand. In FIGS. 5 to 13, the case where the dominant hand is the right hand is described. However, even when the dominant hand is the left hand, the page turning operation can be determined by the same method.

  As described above, in the handwriting input device 10 of the present embodiment, the user moves his / her finger so as to actually turn the page (the touch position of the finger on the release end side of the paper moves toward the fixed end side of the paper). ), And the touch panel control unit 13 determines that the page turning operation has been performed, so that the handwritten data is stored for each page by natural operation without requiring special paper, special components, or special operations. The operability of the handwriting input device 10 can be significantly improved.

  Note that the present invention is not limited to the above embodiment, and the configuration and control method of the handwriting input device 10 can be changed as appropriate without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the pen is exemplified as the first input unit that performs the handwriting input operation, and the finger is illustrated as the second input unit that performs the page turning operation. However, the second input unit is the first input unit. The area of the part that presses the touch panel 14 may be larger than the means, and the first input means may be a pen with a relatively thin pen tip, and the second input means may be a pen with a relatively thick pen tip. Is possible.

  Moreover, in the said Example, although the touchscreen 14 was comprised with the pressure-sensitive touch sensor and discriminate | determined handwriting input operation and page turning operation by the touch position and the touch pressure, for example, an electromagnetic touch sensor is added and electromagnetic The operation detected by the type touch sensor may be determined as a handwriting input operation, and the operation detected by the pressure-sensitive type touch sensor may be determined as a page turning operation.

  Moreover, in the said Example, it was set as the structure which only operates with the touchscreen 14, However, The touchscreen 14 is set as the structure which has arrange | positioned the touch sensor on display parts, such as LCD (Liquid Crystal Display), and performs an operation and display with the touchscreen 14. It can be configured.

  The present invention can be used for a handwriting input device including a pressure-sensitive touch panel and a program that operates on the handwriting input device.
