The handwriting input device comprises a function control part which determines whether the pen and the finger contact on the touch panel simultaneously on the basis of contact position information detected by the touch panel, determines, when the pen and the finger contact on the touch panel simultaneously, whether a contact position of the finger is within a range which can be pointed by the hand holding the pen, and switches a function concerning the handwriting input when the pen and the finger contact on the touch panel simultaneously, and further the contact position of the finger is within the range.

Description

  The present invention relates to a handwriting input device and a function control program, and more particularly to a handwriting input device including a touch panel capable of multi-touch and a function control program for controlling functions related to handwriting input.

  In recent years, handwriting input devices such as tablet terminals that perform handwriting input with a touch panel have become widespread. In this handwriting input device, a finger or stylus pen (hereinafter simply referred to as a pen) is touched and slid on the touch panel to perform handwriting input operations such as drawing or erasing characters, pictures, figures, etc. It can be carried out.

  Regarding such a handwriting input operation, for example, in Patent Document 1 below, a finger detection unit that is provided on a display screen and detects coordinates touched by a finger / hand and outputs a first detection signal; and the display screen And a pen detection means for detecting a coordinate touched by the pen and outputting a second detection signal, and when the pen is used, a pointing is extracted from the second detection signal and a pointing instruction is issued. And a signal processing means for extracting only a predetermined gesture from the first detection signal and issuing a corresponding command.

JP 2011-186550 A

  Here, many users perform input operations on the handwriting input device with the dominant hand while supporting the handwriting input device with the hand opposite to the dominant hand. In addition to drawing characters, pictures, figures, etc., this input operation includes pen and finger strokes, such as coloring important points by color, drawing markers, connecting them with link lines, and grouping them together. There is also an operation having a certain functional meaning different from a so-called normal operation in which only is displayed.

  When an operation having such a functional meaning is performed in the middle of handwriting, the handwriting operation is temporarily interrupted, a predetermined button is touched or a predetermined button is pressed to display a menu, and a desired menu is displayed from the menu. Then, the handwriting operation is resumed. When using the method of Patent Document 1, the handwriting operation with one of the pen or the finger is temporarily interrupted, the function is set with the other of the pen or the finger, and the handwriting operation with one of the pen or the finger is performed again. Will resume.

  As described above, in the conventional method, handwriting input and function setting cannot be performed by a series of operations, and the operability of the handwriting input device is used when performing an operation of setting a function in the middle of handwriting operation. There was a problem that the remarkably deteriorated.

  The present invention has been made in view of the above problems, and its main purpose is to provide a handwriting input device and a function control program capable of switching functions without selecting a menu only with a hand holding a pen. It is to provide.

  In order to achieve the above-described object, an apparatus reflecting one aspect of the present invention is a handwriting input device that performs handwriting input using a touch panel that is arranged on a display unit and can identify a pen and a finger. Based on the contact position information detected by the touch panel, it is determined whether the pen and the finger are in contact at the same time. If the pen and the finger are in contact at the same time, the contact position of the finger is the pen. A function relating to handwriting input when the finger and the finger are in contact with each other at the same time, and the contact position of the finger is within the range The function control part which performs switching of is provided.

  A program reflecting one aspect of the present invention is a function control program that operates on a device that performs handwriting input using a touch panel that is identifiable on a pen and a finger and that is arranged on a display unit. First determination processing for determining whether the pen and the finger are in contact at the same time based on the contact position information detected by the touch panel, and when the pen and the finger are in contact at the same time, In the second determination process for determining whether the finger contact position is within a range in which the finger of the hand holding the pen can specify, it is determined that the pen and the finger are in contact at the same time. And when it determines with the contact position of the said finger | toe being in the said range by the said 2nd determination process, the function control process which switches the function regarding handwriting input is performed.

  According to the handwriting input device and the function control program of the present invention, it is possible to switch functions without selecting a menu with only a hand holding a pen.

  The reason is that the handwriting input device (function control program) determines whether the pen and the finger are in contact at the same time. If the pen and the finger are in contact at the same time, the contact position of the finger is the contact position of the pen. This is because the function relating to handwriting input is switched when the pen and the finger are in contact with each other at the same time and the contact position of the finger is in the vicinity of the contact position of the pen.

It is a figure explaining the effect of one Example of this invention. It is a figure explaining the effect of one Example of this invention.

  As shown in the background art, when using a handwriting input device, a handwriting input operation is normally performed with a dominant hand while supporting the handwriting input device with a hand opposite to the dominant hand. Therefore, when performing a function switching operation that is different from normal handwriting during the handwriting operation of drawing characters, pictures, figures, etc., the handwriting operation is temporarily interrupted and the menu is displayed, and the desired menu is displayed. You must select the function and perform the handwriting operation again.

  In other words, the handwriting input device is supported by the hand opposite to the dominant hand, and it is difficult to perform the function switching operation with the supporting hand, so both the handwriting operation and the function switching operation must be performed with the dominant hand. Therefore, handwriting input cannot proceed smoothly.

  Therefore, in one embodiment of the present invention, in a handwriting input device equipped with a touch panel capable of detecting simultaneous input by a pen and a finger, it is determined whether the pen and the finger are in contact at the same time, and the pen and the finger are simultaneously If contact is made, determine whether the finger contact position is in the vicinity of the pen contact position (a range that can be indicated by the finger of the hand holding the pen), the pen and the finger are in contact at the same time, and When the contact position of the finger is in the vicinity of the contact position of the pen, the function relating to handwriting input is switched. Also, when switching functions, refer to pre-stored association information based on information about the finger (such as the relative positional relationship between the pen and the finger, the distance between the pen and the finger, the number of fingers, and the type of finger). Control to set the switching function.

  This makes it possible to switch functions related to pen input while maintaining the conventional handwriting operation using only the dominant hand holding the pen without having to use the hand supporting the handwriting input device. In addition, since an operation for selecting a function from a menu is not necessary, it is possible to switch functions during successive handwriting operations.

  In order to describe the above-described embodiment of the present invention in more detail, a handwriting input device and a function control program according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing the main configuration of the handwriting input device of this embodiment, and FIGS. 2 and 8 are flowcharts showing the operation of the handwriting input device. 3 to 7 are diagrams showing the relationship between the pen and the finger, and FIG. 9 is an example of association information used by the handwriting input device of this embodiment. FIGS. 10 to 16 are diagrams schematically illustrating the operation of the handwriting input device according to the present embodiment, and FIGS. 17 and 18 are diagrams illustrating the effects of the present embodiment.

  The handwriting input system according to the present embodiment includes a pen 102 and a finger 103 that perform handwriting input, a handwriting input device 101 such as a tablet terminal, a mobile phone, or a notebook personal computer device that can perform handwriting input using the 102 and the finger 103; Consists of.

  FIG. 1 is a block diagram showing the main configuration of the handwriting input device 101 of this embodiment. The handwriting input device 101 includes an input unit (touch panel) 104, an input determination unit 105, a function switching unit 106, a pen input function unit 107, a finger input function unit 108, a simultaneous input function unit 109, a display unit 110, and the like.

  The input unit 104 is an electrostatic, electromagnetic, or pressure-sensitive touch panel in which transparent electrodes are arranged in a grid pattern on the display unit 110, and inputs and determines contact position information of the pen 102 and the finger 103 on the touch panel. Notification to the unit 105. The input unit 104 can detect the contact of the pen 102 and the contact of the finger 103 at the same time, and determines whether the contact of the pen 102 or the contact of the finger 103 is based on the area, shape, pressing force, etc. It has a structure that can be discriminated based on it. The touch panel may detect the contact of the pen 102 and the contact of the finger 103 in the same manner (for example, detect both contacts by changing the capacitance), or contact the pen 102 and the contact of the finger 103. May be detected by different methods (for example, pen contact is detected by a magnetic change, and finger contact is detected by a capacitance change).

  The input determination unit 105 determines whether the contact object is the pen 102 or the finger 103 based on the contact position information notified from the input unit 104 based on the area or size of the contact part, And the finger 103 are determined to move in parallel, the relative positional relationship between the contact position of the pen 102 and the contact position of the finger 103 is determined, or the distance between the contact position of the pen 102 and the contact position of the finger 103 , The number of touching fingers 103, or the type of touching finger 103 is determined. Then, with reference to the association information between the input pattern and the execution function, which will be described later, it is determined whether the input pattern of the pen 102 and the finger 103 corresponds to the default input pattern, and the determination result is notified to the function switching unit 106.

  The function switching unit 106 performs control to switch functions based on the determination result notified from the input determination unit 105. Specifically, when only the pen 102 is input, the pen input function unit 107 is controlled to execute a predetermined function. When only the finger 103 is input, the finger input function The unit 108 is controlled to execute a predetermined function, and when the pen 102 and the finger 103 are simultaneously input, the simultaneous input function unit 109 is controlled to execute a function according to the determination result.

  In this embodiment, the input determination unit 105 and the function switching unit 106 are configured separately, but they may be integrated as a function control unit. The input determination unit 105 and the function switching unit 106 may be configured as hardware, or may be configured by a CPU (Central Processing Unit) and a memory such as a ROM (Read Only Memory) or a RAM (Random Access Memory). It may be configured as a function control program that operates on the control unit.

  The pen input function unit 107 is a part that executes a function according to the control of the function switching unit 106 when only the pen 102 is input. The finger input function unit 108 is a part that executes a function according to the control of the function switching unit 106 when only the finger 103 is input. The simultaneous input function unit 109 is a part that executes a function according to the control of the function switching unit 106 when simultaneous input of the pen 102 and the finger 103 is performed.

  The functions to be executed include, for example, a function for connecting handwritten input characters, pictures, figures, etc. (referred to as objects) with link lines, a function for deleting part or all of handwritten input objects, Function to add color to the background for emphasis, Function to add color to an object, Function to text an object using OCR (Optical Character Reader) technology, Function to group multiple objects, Predetermined figure But is not limited to this.

  The display unit 110 is an LCD (Liquid Crystal Display) or the like, and displays a handwritten input object, a document based on document data, an image based on image data, and the like. In addition, a result of executing each function according to the operation of the pen 102 and / or the finger 103 is also displayed.

  Next, a specific operation of the handwriting input device 101 of the present embodiment will be described with reference to the flowchart of FIG.

  First, the input unit 104 detects handwriting input of the pen 102 and / or the finger 103 to an inputable area, and notifies the input determination unit 105 of contact position information (S101). As described above, the method for detecting the handwritten input is not limited, but at least it is detected so that it can be determined whether the input is performed with the pen 102 or the input with the finger 103.

  Next, the input determination unit 105 determines whether or not the pen 102 and the finger 103 are simultaneously input based on the contact position information acquired from the input unit 104 (S102). Specifically, as described above, when the input by the pen 102 and the input by the finger 103 are identified based on the area and shape of the contact portion, the pressing force, etc., and the input is detected at two places, 2 It is discriminated whether the input is from both the pen 102 and the finger 103 instead of the pen and two fingers.

  If it is not simultaneous input of the pen 102 and the finger 103, the input determination unit 105 notifies the determination result to the function switching unit 106, and the function switching unit 106 uses the pen input function unit 107 or the finger input function unit 108 as usual. Control is performed to execute individual pen / finger functions (S107).

  In the case of simultaneous input from the pen 102 and the finger 103, the input determination unit 105 determines whether or not the input is a finger near the pen based on the contact position information acquired from the input unit 104 (S103). Specifically, when the position where the finger 103 is in contact is within a range where the finger of the hand on the side of the pen 102 can reach, it is determined that the input is a finger near the pen. For example, as shown in FIG. 3A, when the contact position of the finger 103 is within a range of X mm around the contact position of the pen 102, or as shown in FIG. When the position is a specific position with respect to the contact position, it can be determined that the finger input is in the vicinity of the pen.

  If the finger input is not near the pen, the input determination unit 105 notifies the function switching unit 106 of the determination result, and the function switching unit 106 controls the pen input function unit 107 or the finger input function unit 108 as usual. The pen / finger individual function is executed (S107).

  In the case of finger input near the pen, the input determination unit 105 determines whether the input pattern is a default input pattern (S104). Specifically, as shown in FIG. 4A, when the movement locus of the contact position of the pen 102 and the movement locus of the contact position of the finger 103 have substantially the same shape, it is determined that the input pattern is the default input pattern. To do. On the other hand, as shown in FIG. 4B, when the finger 103 moves in the opposite direction to the movement of the pen 102, or as shown in FIG. If 103 is stationary, it is determined that the input pattern is not the default. Even when a finger input in the vicinity of the pen is detected, such a determination may be made by contact of the finger 103 (unintentional finger contact) unrelated to the function switching. This is because it is not appropriate to switch functions in such cases.

  If the input pattern does not match the default input pattern, the input determination unit 105 notifies the function switching unit 106 of the determination result, and the function switching unit 106 performs the pen input function unit 107 or the finger input function unit 108 as usual. Are controlled to execute individual pen / finger functions (S107).

  On the other hand, if the input pattern matches the default input pattern, the input determination unit 105 notifies the function switching unit 106 of the determination result, and the function switching unit 106 controls the simultaneous input function unit 109 to input the input pattern. The function corresponding to the is executed (S105).

  Thereafter, the input determination unit 105 determines whether the simultaneous input of the pen 102 and the finger 103 is continuously performed (S106). If the simultaneous input of the pen 102 and the finger 103 is continued, the process returns to S105. Maintain the execution state of the function. On the other hand, when the simultaneous input of the pen 102 and the finger 103 is not performed, the function being executed is terminated and the state of waiting for input is continued.

  As described above, when the pen 102 and the finger 103 are simultaneously input and the finger input is in the vicinity of the pen (in other words, when the pen 102 and the finger 103 are not simultaneously input and the finger input is not in the vicinity of the pen, the pen Executes the function according to the input pattern except when the input is 102 and the finger 103 at the same time and is not the finger input near the pen (except when the input is not the simultaneous input of the pen 102 and the finger 103 but the finger input near the pen). By doing so, the user can perform handwriting input and function switching through a series of operations, and thus the operability of the handwriting input device 101 can be significantly improved.

  Further, when the pen 102 and the finger 103 are input simultaneously, the finger input is in the vicinity of the pen, and the pen 102 and the finger 103 are moving in conjunction with each other, the function corresponding to the input pattern is executed. Since the inconvenience that the function is switched due to unintended finger contact can be prevented, the operability of the handwriting input device 101 can be significantly improved.

  Next, functions according to the input pattern will be described.

  The function corresponding to the input pattern can be set based on the relative positional relationship between the contact position of the pen 102 and the contact position of the finger 103. Specifically, as shown in FIG. 5, when the contact position of the finger 103 (shaded circle in the figure) is based on the direction of the handwriting input device 101, the contact position of the pen 102 (black in the figure). When the position is up / right / left / bottom with respect to the fill circle), the functions can be associated with the top / right / left / bottom. In addition, functions can be associated with each other according to the distance (Ymm in the drawing) between the contact position of the pen 102 and the contact position of the finger 103. In addition, functions can be associated with both the direction and distance of the contact position of the finger 103 with respect to the contact position of the pen 102.

  The function corresponding to the input pattern can be set based on the number of fingers. Specifically, as shown in FIG. 6, function A is used when the number of fingers is one, function B is used for two fingers, function C is used for three fingers, and function D is used for four fingers. Functions can be associated.

  Also, the function corresponding to the input pattern can be set based on the type of finger. For example, the display unit 110 of the handwriting input device 101 is a transmissive LCD so that a fingerprint of a finger can be photographed from the back of the display unit 110, and the fingerprint of the photographed finger and the fingerprint of each user registered in advance are patterned. The finger can be specified by collation. Then, as shown in FIG. 7, according to the type of each specified finger, function A is indicated for the index finger, function B for the middle finger, function C for the ring finger, and function D for the little finger. Can be associated. Note that the finger can be specified by the size and shape of the finger instead of the fingerprint of the finger. In that case, the contour of the contact portion detected by the input unit 104 is extracted, and the finger is identified and identified by pattern matching the size and shape of the contour with the size and shape of each user's finger stored in advance. Functions can also be associated with each finger type.

  Hereinafter, the procedure for setting the function according to the input pattern will be described with reference to the flowchart of FIG. When setting the function according to the input pattern, as shown in FIG. 9, the combination of the position of the finger 103 with respect to the pen 102, the distance between the pen 102 and the finger 103, the number of fingers 103, and the type of the finger 103, and the function to be executed Is created in advance and stored in advance in the handwriting input device 101 or in a place where the handwriting input device 101 can refer (for example, a server connected to the handwriting input device 101 via a network). It shall be.

  First, in S103 of FIG. 2 described above, when the input determination unit 105 determines that the input is in the vicinity of the pen, information on the relative position of the finger 103 with respect to the pen 102, information on the distance between the pen 102 and the finger 103, and information on the finger 103 Information on the number of pieces and information on the type of the finger 103 are acquired (S201 to S204).

  Then, the input determination unit 105 determines whether the input pattern corresponds to the default input pattern described in the association information in FIG. 9 (whether the pen 102 and the finger 103 are moved in conjunction with each other if necessary). If it is determined (S205) and the input pattern does not correspond to the default input pattern, the pen / finger individual function is executed in S107 of FIG. 2, and if it corresponds to the default input pattern, the process of FIG. The function associated with the input pattern by the association information is executed.

  A function associated with this input pattern will be specifically described with reference to schematic diagrams of FIGS.

  When only the pen 102 is in contact with the input unit 104, a “handwriting” function for displaying the stroke following the stroke is executed. For example, as shown in FIG. 10A, when the characters “postcard” and the characters “GO!” Are drawn, each character is registered as an individual object. In this state, as shown in FIG. 10B, when the pen 102 is brought into contact with the object of “postcard” and at the same time, the finger 103 (middle finger) is brought into contact with the pen 102 in the vicinity of the pen 102 ( In the drawing, the contact position is indicated by a large black circle for easy understanding.) Based on the association information in FIG. 9, the “link between objects” function corresponding to this input pattern is executed. . Then, as shown in FIG. 10C, when the pen 102 and the finger 103 are moved to the “GO!” Object at the same time, the “postcard” object and the “GO!” Object are displayed. Connected with a link line.

  Similarly, in the state where “Foreword” and “GO!” Are registered as individual objects (see FIG. 11A), as shown in FIG. When the two fingers 103 (middle finger and ring finger) are brought into contact with the pen 102 in the vicinity of the pen 102 and on the upper side of the pen 102 at the same time, the input pattern corresponding to this input pattern is set based on the association information shown in FIG. The “eraser” function is executed. Then, as shown in FIG. 11C, when the pen 102 and the two fingers 103 are moved simultaneously on the “word” object, the movement locus is not determined by handwriting input. The part corresponding to the movement trajectory of the “word” object is not displayed on the display unit 110 and is erased.

  Similarly, in the state where “Foreword” and “GO!” Are registered as individual objects (see FIG. 12A), as shown in FIG. If the finger 103 (middle finger) is brought into contact with the pen 102 at a position 10 mm or more in the vicinity of the pen 102 and on the right side of the pen 102 at the same time, this input pattern is handled based on the association information shown in FIG. The “marker” function is executed. Then, as shown in FIG. 12C, if the pen 102 and the finger 103 are moved on the “word” object while being in contact with each other at the same time, the movement locus is not determined by handwriting input. The object is emphasized by adding a predetermined color to the background of the “word” object or by reversing it in black and white.

  Similarly, in the state where “postcard” and “GO!” Are registered as individual objects (see FIG. 13A), as shown in FIG. When two fingers 103 (middle finger and ring finger) are brought into contact with the pen 102 in the vicinity of the pen 102 and the right side of the pen 102, the “textification” function corresponding to this input pattern is executed based on the association information in FIG. . Then, when the “ISP” character is handwritten while the pen 102 and the finger 103 are in contact with each other at the same time, as shown in FIG. 13C, the handwritten character is recognized using a known OCR technique. Is displayed.

  Similarly, in the state where “postcard” and “GO!” Are registered as individual objects (see FIG. 14A), as shown in FIG. When the finger 103 (middle finger) is brought into contact with the pen 102 in the vicinity of the pen 102 and the left side of the pen 102, the “group multiple objects” function corresponding to this input pattern is executed based on the association information shown in FIG. Then, as shown in FIG. 14C, when the pen 102 and the finger 103 are simultaneously in contact with each other and moved so as to surround the object of “postcard” and the object of “GO!”, Objects and "GO!" Objects are grouped.

  Similarly, in the state where “postcard” and “GO!” Are registered as individual objects (see FIG. 15A), as shown in FIG. When two fingers 103 (middle finger and ring finger) are brought into contact with the pen 102 in the vicinity of the pen 102, the "figure: square drawing" function corresponding to this input pattern is created based on the association information shown in FIG. Executed. When a line is handwritten while the pen 102 and the finger 103 are in contact with each other at the same time, the movement trajectory is not determined by handwriting input and is not displayed on the display unit 110. As shown in FIG. A rectangle with the start point and end point as diagonals is displayed.

  Also, as shown in FIG. 16A, when the pen 102 is brought into contact with the finger 103 (middle finger) in the vicinity of the pen 102 and on the right side of the pen 102, this is based on the association information in FIG. The “red” function corresponding to the input pattern is executed. When a line is handwritten while the pen 102 and the finger 103 are in contact with each other at the same time, the movement trajectory is drawn as a red line (in the figure, shaded red is used). Thereafter, as shown in FIG. 16B, both or either of the pen 102 and the finger 103 that are simultaneously in contact with each other are separated from the surface of the input unit 104 (in the drawing, the finger 103 is separated from the surface of the input unit 104. When only the pen 102 is touched, the “red” function ends and the handwritten line is displayed in black.

  As described above, by switching the function according to the input pattern, the user can execute various functions while performing handwriting input. Therefore, the operability of the handwriting input device 101 can be further improved.

  10 to 16 are examples, and how to hold the pen 102, the arrangement of the finger 103, the part of the finger 103 that is brought into contact with the input unit 104, and the like are not limited to the configuration shown in the figure.

  Further, in the above description, when one or both of the pen 102 and the finger 103 are separated from the surface of the input unit 104, the function is immediately terminated. However, one or both of the pen 102 and the finger 103 is connected to the input unit 104. The function may be terminated after elapse of a predetermined time after leaving the surface. That is, when the time away from the surface of the input unit 104 is a short time, it may not be regarded as being away and the execution of the function may be continued. By monitoring the passage of time in this way, it is possible to prevent inconvenience that the function ends when the pen 102 or the finger 103 is unintentionally left.

  Hereinafter, the effects of the present embodiment will be described in detail with reference to FIGS. 17 and 18.

  For example, when handwriting a link diagram (mind map) as shown in FIG. 17 (a), each item may be normal handwriting, but the line connecting them can be expanded or contracted according to the position of the object, or branched. It is necessary to make adjustments, and the function as a link line is required while being the same handwriting. At that time, if the function of the link line is selected from the menu as in the conventional case, the function must be switched on / off every time the item and the link line appear alternately, and the operation is complicated. Become.

  In such a case, when the handwriting input device 101 of the present embodiment is used, as shown in FIG. 17B, there is no work to switch the function between the input of the item and the link line. Can be done automatically. Accordingly, not only switching of unit functions is facilitated, but also operability of handwriting input can be improved.

  Also, as shown in Fig. 18 (a), when writing to a document while hearing, listen to the person's story while looking at the conference material, such as during a seminar, and document important points for yourself The work of appending and highlighting is often done.
