Description

  The present invention relates to a display object management apparatus and a display object management program capable of displaying a display object for displaying document information on a display screen and additionally writing it.

  In recent years, an application for creating and displaying a display object in which document information such as a character string is entered as a virtual sticky note on a display screen of an information device such as a personal computer, or a WEB service has become widespread.

  In addition, the contents of the memo written by the user on the memo paper etc. with the writing instrument are optically captured as image data with a scanner or digital camera, and the image data is adjusted to a size that can be viewed appropriately. A technique for displaying the virtual sticky note on the screen has been proposed (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2008-145887

  On the other hand, when a new virtual sticky note is pasted and displayed on the display screen, it is necessary to paste and display the existing virtual sticky note so as not to overlap as much as possible so as to ensure the visibility. However, in a state where a large number of virtual sticky notes have already been pasted and displayed at a predetermined location on the display screen, the area where a new virtual sticky note can be pasted is limited to a narrow range so as to avoid the duplication described above at that location. It will be limited.

  According to the above prior art, the entire virtual sticky note paper can be reduced together with the image data to be pasted and displayed in the narrow limited area. However, in this case, since the handwritten character image described in the image data is also reduced, the visibility of the description content is reduced and the display becomes complicated. In order to avoid such an inconvenience, it has been necessary to paste and display a new virtual sticky note at a place with other margins contrary to the user's intention.

  An object of the present invention is to provide a display object management apparatus and a display object management program capable of avoiding complicated display of display objects and capable of creating display objects with a high degree of freedom.

  In order to achieve the above object, the first invention receives position information of an electronic writing instrument for inputting data corresponding to the writing content to the writing instrument from the external operation terminal, and displays it on the display means. A display object management apparatus capable of displaying an object, wherein a paste reference position acquisition for obtaining a reference position of a paste area designated when a new display object is pasted and displayed by a user in the display area coordinates of the display means Stroke data acquisition means for acquiring stroke data corresponding to writing contents by the electronic writing instrument based on the reception result of the position information from the external operation terminal as data to be entered in the new display object; The stroke data is divided into character image data units for one character or a plurality of characters and entered in order of entry. Data conversion means for converting to a character image data string arranged side by side, and the new display object is pasted and displayed according to the line length at a predetermined display magnification of the character image data string converted by the data conversion means An initial area setting means for setting an initial size of a new pasting area, and the new pasting area having an initial size set by the initial area setting means at the reference position acquired by the pasting reference position acquisition means. In the case where a new display object is pasted and displayed, the duplication judgment means for judging whether the new pasting area overlaps with an existing pasting area of another existing display object in a predetermined judgment direction, and the duplication judgment means are duplicated. Then, when it is determined, from the reference position acquired by the pasting reference position acquisition unit, to the existing pasting area determined that the duplication determination unit is duplicated Based on the separation distance detection means for detecting the separation distance in the predetermined determination direction and the separation distance in the predetermined determination direction detected by the separation distance detection means, the new pasting region is positioned at the reference position. When changing the size of the new pasting area so that it does not overlap with the existing pasting area in the predetermined determination direction, the size of the new pasting area changed by the pasting area changing means, When all the character image data in the character image data string can be listed at the predetermined display magnification, all the character image data in the new pasting area at the reference position obtained by the pasting reference position obtaining unit. And a new pasting means for pasting and displaying the new display object.

  In the first invention of this application, the position information on the writing instrument of the electronic writing instrument is received from the external operation terminal, and the display object can be displayed on the display means.

  On the display means, the user can create a plurality of display objects at arbitrary positions in the display area, and input and display arbitrary character data in the form of stroke data in the existence area. The stroke data is handled by being divided in units of character image data for one character or a plurality of characters. Further, when creating and pasting a new display object, it is desirable to limit the pasting position so that the existing display object does not overlap with the pasted display area. Thus, the display means can be used for display of the display object application.

  Therefore, in the first invention of the present application, the pasting reference position acquisition means acquires the reference position of the pasting area of the new display object designated by the user. In addition, based on the reception result of the position information from the external operation terminal, the stroke data acquisition unit acquires stroke data corresponding to the writing content by the electronic writing instrument. Further, the data conversion means converts the stroke data into a character image data string divided in character image data units for one character or a plurality of characters and arranged in the order of entry. The initial area setting means sets an initial size of a new pasting area for pasting and displaying a new display object according to a list length in which character image data strings are arranged at a predetermined interval at a predetermined display magnification. .

  Here, when a new display object is pasted and displayed at the reference position with a new pasting area having an initial size, the new pasting area is in a predetermined determination direction with another pasting area of another existing display object. If they do not overlap, they can be pasted and displayed as they are. However, if it is determined that the duplication determination means is duplicated, if the new display object is pasted and displayed as it is, the character data written in the existing display object is covered with the new display object and cannot be seen.

  Therefore, the separation distance in the predetermined determination direction from the reference position to the existing pasting area is detected by the separation distance detection means. The pasting area changing means changes the size of the new pasting area based on the detected separation distance so that the new pasting area does not overlap the existing pasting area in the predetermined determination direction when the new pasting area is located at the reference position. To do. Then, the new pasting means determines whether all the character image data in the character image data string can be listed at a predetermined display magnification with the changed size of the new pasting area. A new display object is pasted and displayed at the position in the new pasting area.

  Accordingly, the first invention of the present application can paste and display a new display object at the reference position designated by the user while maintaining the display magnification of the character image data string without overlapping with the existing display object. As a result, complicated display of the display object can be avoided, and a display object with a high degree of freedom can be created.

  In a second aspect based on the first aspect, the data conversion means further comprises a list direction determining means for determining a list direction of the character image data when the stroke data is converted into the character image data string. The initial area setting means performs a line feed in a line feed direction corresponding to the list direction so that the list length of the character image data string in the list direction determined by the list direction determination means falls within a predetermined initial length. The initial size of the new pasting area is set by arranging the character image data.

  In the second invention of the present application, the list direction determining means provided in the data conversion means determines whether the list direction of the character image data is the right direction in the case of horizontal writing or the downward direction in the case of vertical writing. The initial area setting means arranges the character image data by making a line break in the line feed direction corresponding to the row direction so that the row length of the character image data row in the row direction falls within a predetermined initial length. Here, the line feed direction is the downward direction when the listing direction is the right direction of horizontal writing, and the left direction when the listing direction is the downward direction of vertical writing. In this way, the size when all the character image data is arranged in the row direction and the line feed direction is set as the initial size of the new pasting area. Thus, a new display object can be initially set in a natural rectangular shape, and it is easy to specify a position that assumes the shape even when the user specifies the pasting position.

  According to a third aspect, in the second aspect, when it is determined that the overlap determination unit overlaps, the separation distance detection unit sets each of the list direction and the line feed direction as the predetermined determination direction. The separation distance is detected.

  In the third invention of the present application, the separation distance detection means detects the separation distance in both the list direction and the line feed direction from the reference position. As a result, it is possible to detect a separation distance appropriately corresponding to the case where the character image data string is written horizontally or vertically.

  A fourth invention is characterized in that, in the second or third invention, the data conversion means newly collects a plurality of continuous character image data constituting one clause as one character image data.

  In the fourth invention of the present application, since a plurality of character image data constituting one clause is not separated even at a line break in the character image data string, the character image data string can be read with a natural break and read. it can.

  In order to achieve the above object, the fifth aspect of the invention relates to a display means for receiving the position information of the electronic writing instrument for inputting data corresponding to the writing contents to the writing instrument from the external operation terminal. The reference position of the pasting area designated when a new display object is pasted and displayed by the user in the display area coordinates of the display means to the control means provided in the display object management apparatus capable of displaying the display object A stroke reference corresponding to the writing content by the electronic writing instrument is acquired based on the reception result of the position information from the external operation terminal as data to be entered in the new display object and the paste reference position acquisition procedure The stroke data acquisition procedure to be performed, and the stroke data for character image data for one character or a plurality of characters. According to the data conversion procedure for converting into a character image data string that is divided in units of data and arranged in the order of entry, and according to the column length at a predetermined display magnification of the character image data string converted by the data conversion procedure, An initial area setting procedure for setting an initial size of a new pasting area for pasting and displaying a new display object, and an initial set in the initial area setting procedure at the reference position acquired in the pasting reference position acquisition procedure A duplication determination procedure for determining whether the new pasting area overlaps with an existing pasting area of another existing display object in a predetermined direction when a new display object is pasted and displayed on the new pasting area of a large size; Before determining that the duplication determination procedure overlaps from the reference position acquired in the pasting reference position acquisition procedure when it is determined that the duplication determination procedure overlaps Based on the separation distance detection procedure for detecting the separation distance in the predetermined determination direction to the existing application region, and the separation distance in the predetermined determination direction detected in the separation distance detection procedure, the new application region is A pasting area change procedure for changing the size of the new pasting area so that it does not overlap with the existing pasting area in the predetermined determination direction when pasting and displaying at a reference position, and the new pasting changed by the pasting area changing procedure When all the character image data of the character image data string can be listed at the predetermined display magnification by the size of the area, the reference position acquired in the attachment reference position acquisition procedure is used for the new application area. And a new pasting procedure for pasting and displaying the new display object listing all the character image data.

  In the fifth invention of this application, the display object management device can receive the position information of the electronic writing instrument on the writing instrument from the external operation terminal and can display the display object on the display means.

  On the display means, the user can create a plurality of display objects at arbitrary positions in the display area, and input and display arbitrary character data in the form of stroke data in the existence area. The stroke data is handled by being divided in units of character image data for one character or a plurality of characters. Further, when creating and pasting a new display object, it is desirable to limit the pasting position so that the existing display object does not overlap with the pasted display area. Thus, the display means can be used for display of the display object application.

  Therefore, in the fifth invention of the present application, the sticking reference position acquisition procedure acquires the reference position of the sticking area of the new display object designated by the user. Further, based on the reception result of the position information from the external operation terminal, the stroke data acquisition procedure acquires stroke data corresponding to the writing content by the electronic writing instrument. Also, the data conversion procedure converts the stroke data into a character image data string that is divided into character image data units for one character or a plurality of characters and arranged in the order of entry. The initial area setting procedure sets the initial size of a new pasting area for pasting and displaying a new display object in accordance with the row length of character image data rows arranged at a predetermined interval at a predetermined display magnification. .

  Here, when a new display object is pasted and displayed at the reference position with a new pasting area having an initial size, the new pasting area is in a predetermined determination direction with another pasting area of another existing display object. If they do not overlap, they can be pasted and displayed as they are. However, when it is determined that the duplication determination procedure is duplicated, if a new display object is pasted and displayed as it is, the character data written in the existing display object is covered with the new display object and cannot be seen.

  Therefore, the separation distance in the predetermined determination direction from the reference position to the existing pasting area is detected by the separation distance detection procedure. In addition, the pasting area changing procedure changes the size of the new pasting area based on the detected separation distance so that the new pasting area does not overlap the existing pasting area in the predetermined determination direction when the new pasting area is located at the reference position. To do. Then, the new pasting procedure determines whether or not all the character image data in the character image data string can be listed at a predetermined display magnification with the changed size of the new pasting area. A new display object is pasted and displayed at the position in the new pasting area.

  Accordingly, the fifth invention of the present application can paste and display a new display object at the reference position designated by the user while maintaining the display magnification of the character image data string without overlapping with the existing display object. As a result, complicated display of the display object can be avoided, and a display object with a high degree of freedom can be created.

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

  The virtual sticky note input / display system S according to the present embodiment having the display object management apparatus of the present invention has a plurality of writing panels connected to each other via a communication network NW so as to be able to send and receive information as shown in FIG. 1, a server 2, and a display device 3. The writing panel 1 that is an external operation terminal includes an electronic pen 11 and a panel device 12, and stroke data that is input by the user to the panel device 12 using the electronic pen 11 that is an electronic writing tool is electronically written. This is an operation terminal that creates and displays a virtual sticky note as a display object in which the stroke data is entered. The server 2 that is a display object management device is an information processing device that is configured by a general computer and processes a virtual sticky note application described later, and is created based on stroke data transmitted from each writing panel 1 and various commands. The virtual sticky notes that have been sent are managed, and these virtual sticky notes are displayed on the display device 3 as display means. On the display screen of the display device 3, a plurality of virtual sticky notes created by operating each writing panel 1 are pasted and displayed on the same virtual bulletin board, and each user of each writing panel 1 displays the display device 3. Share and view the display. In the illustrated example, the communication network NW that connects each writing panel 1 and the server 2 is a wired network via a cable, but may be connected via a wireless network.

  As shown in FIGS. 2A and 2B, the panel device 12 includes a liquid crystal panel 13 and a panel body 14 that is arranged so as to overlap the back side and is fixed integrally. The liquid crystal panel 13 which is a writing instrument is configured to be able to pass through a magnetic field as a whole, and its display area is formed to be approximately the same size as the panel body 14. The panel body 14 includes a coil sheet 100 having a size substantially equal to that of the panel body 14 therein.

  The user writes a desired handwritten character string or the like on the writing surface of the liquid crystal panel using the electronic pen 11. By the movement of the electronic pen 11 corresponding to the writing operation, electronic input information corresponding to the written content, that is, stroke data described later is stored in the electronic file.

  When the user uses the writing panel 1, a power switch (not shown) provided in the electronic pen 11 is turned on. As shown in FIGS. 3 and 4, the electronic pen 11 that is an electronic writing instrument includes a permanent magnet 47, an LC oscillation circuit 41 that is a position signal generation unit including a magnetic field transmission coil 44 and a capacitor 45, and a tip switch. 42, a control unit 46 that controls the entire electronic pen 11, a control board 40 on which the capacitor 45 is disposed, and a battery 43. The position signal generating means including the magnetic field transmitting coil is not limited to the oscillation circuit such as the LC oscillation circuit 41, and may be a resonance circuit.

  The tip switch 42 operates in accordance with the contact state of the tip of the electronic pen 11 with the liquid crystal panel 13, and sends a command signal S 0 for changing the frequency of an alternating magnetic field (described later) from the coil 44 to the control unit 46. This is a switch that outputs. The tip switch 42 is turned on when the user presses the tip of the electronic pen 11 against the liquid crystal panel 13 (pen down) in order to write characters or the like. In this case, a command signal S0 is output to the control unit 46. On the other hand, when the user stops writing characters or the like and the tip of the electronic pen 11 is separated from the liquid crystal panel 13 (pen-up), it is turned off. In this case, the command signal S0 is not output to the control unit 46.

  The LC oscillation circuit 41 is a circuit for generating and outputting an alternating magnetic field (hereinafter, simply referred to as “magnetic field” as appropriate) which is a position signal for detecting a moving position. The coil 44 of the LC oscillation circuit 41 is disposed so as to be wound around the permanent magnet 47 and is electrically connected to the capacitor 45, and generates a magnetic field having a predetermined frequency generated by the LC oscillation circuit 41. . The frequency of the magnetic field generated from the coil 44 by the LC oscillation circuit 41 is changed by changing the capacitance of the capacitor 45 based on control by the control unit 46 according to whether the tip switch 42 is turned on or off. That is, when the tip switch 42 is on, the control unit 46 to which the command signal S0 is input controls the LC oscillation circuit 41 so as to generate a magnetic field having a specific frequency f1 from the coil 44. On the other hand, when the tip switch 42 is OFF, the control unit 46 to which the command signal S0 is not input controls the LC oscillation circuit 41 so as to generate a magnetic field having a specific frequency f2 from the coil 44. The magnetic field generated from the coil 44 is detected by the panel body 14. By setting f1> f2, it is possible to reduce the power consumption of the electronic pen 2 when generating a magnetic field having a separation frequency f2.

  The battery 43 supplies power to the control unit 46, the LC oscillation circuit 41, and the like when the power switch of the electronic pen 2 is turned on.

  On the other hand, as shown in FIG. 4, the panel body 14 includes a coil sheet 100 and a control circuit unit 20. The coil sheet 100 and the control circuit unit 20 are connected via a signal line.

  The coil sheet 100 includes a sense coil unit 110 as shown in FIG. That is, as shown in FIG. 5, the sense coil portion 110 arranged as shown in FIG.

  As shown in FIG. 5, the sense coil unit 110 includes m loop-shaped sense coils X1 to Xm arranged in the x-axis direction and n loop-shaped sense coils Y1 to Ym arranged in the y-axis direction. Yn. Each of the m sense coils X1 to Xm and the n sense coils Y1 to Yn constituting the sense coil unit 110 is a coil that can receive the magnetic field generated by the coil 44 of the electronic pen 11, It corresponds to a plurality of coils described in each claim. The sense coils X1 to Xm and the sense coils Y1 to Yn are arranged in a positional relationship orthogonal to each other. In addition, the coil surfaces of the sense coils X1 to Xm and Y1 to Yn are substantially parallel to the direction of the writing surface of the memo paper 11. Further, the sense coils X1 to Xm and Y1 to Yn are formed of, for example, copper wires having an insulating coating layer formed on the surface. Still further, the sense coils X1 to Xm, Y1 to Yn are connected to a multiplexer 62 (to be described later) by a lead line not shown and described. Then, the scanning process of the sense coil unit 110 is started, and the sense coils X1 to Xm and Y1 to Yn receive the magnetic field generated by the coil 44 of the electronic pen 11, in other words, the sense coils X1 to Xm and Y1. Electromotive force is generated in the sense coils X1 to Xm and Y1 to Yn due to electromagnetic induction between ~ Yn and the magnetic field generated by the coil 44. That is, the sense coils X1 to Xm and Y1 to Yn generate a signal S1 (see FIG. 4) by magnetic coupling with the coil 44.

  Each of the sense coils X1 to Xm is formed in a substantially rectangular shape including a side having a width P1 in the x-axis direction and a side having a length P2 in the y-axis direction longer than P1. Each of the sense coils X1 to Xm is arranged continuously in the x-axis direction at a predetermined constant pitch. For example, the adjacent sense coils X1 to Xm are overlapped with each other at a half pitch of P1.

  Each of the sense coils Y1 to Yn is formed in a substantially rectangular shape having a side having a width P3 in the x-axis direction and a side having a length P1 in the y-axis direction shorter than P3. Each of the sense coils Y1 to Yn is continuously arranged in the y-axis direction at a predetermined constant pitch. For example, the adjacent sense coils Y1 to Yn are overlapped at a pitch of 1/2 of P1.

  In FIG. 5, for the sake of convenience, the sides of the sense coils X1 to Xm and the sense coils Y1 to Yn are not overlapped for the sake of convenience. Not. In FIG. 5, the shape of the sense coils X <b> 1 to Xm, Y <b> 1 to Yn is illustrated by omitting a lead line entering the multiplexer 62 described later.

  Returning to FIG. 4, the control circuit unit 20 includes a microcomputer 80, a multiplexer 62 (hereinafter referred to as “MUX 62” as appropriate), an amplifier circuit 64, a rectifier circuit 66, a limiter 68, a communication interface 69, and a flash memory. 70 and the liquid crystal panel 13.

  The microcomputer 80 includes a CPU 80a, a ROM 80b, a RAM 80c, and other A / D conversion function units, interrupt function units, and the like as one integrated circuit. The microcomputer 80 controls various processes executed in the panel body and controls the operation states of other peripheral circuits.

  The MUX 62 selects the sense coils X1 to Xm and Y1 to Yn of the sense coil unit 110 one by one based on the coil selection signal S3 from the microcomputer 80. The MUX 62 receives the signal S1 generated in the selected sense coils X1 to Xm, Y1 to Yn, and outputs a corresponding signal S11 to the amplifier circuit 64.

  The amplifier circuit 64 amplifies the signal S11 input from the MUX 62. The signal S12 amplified by the amplifier circuit 64, that is, the electronic pen input detection signal S12 is input to the limiter 68. The limiter 68 processes the signal S12 input from the amplifier circuit 64 into a digital signal S15 having only frequency and phase information, and inputs it to the interrupt input of the microcomputer 80. The microcomputer 80 determines the frequency of the signal S1 from the sense coils X1 to Xm and Y1 to Yn by measuring the period of the signal S15 input from the limiter 68 with a timer or the like, and senses currently being scanned. The data is stored in the RAM 80c together with the coil numbers of the sense coils X1 to Xm and Y1 to Yn of the coil unit 110.

  Another signal S13 amplified by the amplifier circuit 64 is input to the rectifier circuit 66. The rectifier circuit 66 amplitude-detects the signal S13 input from the amplifier circuit 64, smoothes it, and converts it into a DC signal. The signal S14 subjected to amplitude detection by the rectifier circuit 66 is input to the microcomputer 80. As described above, the microcomputer 80 has an A / D conversion function, and converts the input signal S14 after amplitude detection into a digital signal. At this time, the ROM 80b of the microcomputer 80 stores the detection levels of the sense coils X1 to Xm and Y1 to Yn and the offset value of the coordinate data of the contact point between the electronic pen 11 and the liquid crystal panel 13 in association with each other. A position coordinate table is stored (detailed description is omitted). The microcomputer 80 calculates the position information of the electronic pen 11, that is, the x coordinate in the x axis direction and the y coordinate in the y axis direction, by applying a position coordinate table to the digital signal. The calculated position information is stored in the flash memory 70 of the peripheral circuit 70 described later.

  Further, the microcomputer 80, based on the coil numbers of the maximum output sense coils X1 to Xm and Y1 to Yn, stored in the RAM 80c during the scan process of the sense coil unit 110, the sense coils X1 to Xm, The frequency of the signal S1 obtained from Y1 to Yn is detected. Thereby, the frequency value f of the magnetic field received by the sense coils X1 to Xm and Y1 to Yn represented by the coil numbers is detected.

  In this way, the microcomputer 80 receives either the magnetic field having the frequency f1 corresponding to the pen-down state of the electronic pen 11 or the magnetic field having the frequency f2 corresponding to the pen-up state. The position information of the electronic pen 11 can also be calculated. Based on the difference in frequency, it can be determined whether the electronic pen 11 is in the pen-up state or the pen-down state at that time. In the example of the present embodiment, a set of a plurality of pieces of position information calculated while receiving the magnetic field of the frequency f1 corresponding to the pen-down state among these forms the stroke data input by handwriting by the user. .

  The communication interface 69 is an interface for transmitting various information such as stroke data including a plurality of position information stored in the flash memory 70 to the server 2 and receiving predetermined information from the server 2. Specifically, the communication interface 69 is, for example, a USB interface for Universal Serial Bus (USB) connection or a wireless or wired network interface.

  An electronic file is prepared in advance in the flash memory 70, and stroke data based on a plurality of pieces of position information calculated by the microcomputer 80 is written and stored in the electronic file. In addition, the flash memory stores a terminal ID assigned so that the individual writing panel can be identified. When transmitting stroke data to the server 2, the terminal ID is also transmitted together. The server 2 is made to identify the transmission source of the stroke data.

  The panel main body 14 having the above-described configuration has the coordinate position on the liquid crystal panel 13 corresponding to the position information of the electronic pen 11, that is, the electronic pen 11 is in the liquid crystal panel 13 while the electronic pen 11 is in the pen-down state. A locus can be displayed by drawing a point at a position on the surface of the touch panel. Thereby, the stroke data can be electronically displayed on the liquid crystal panel 13 in the same manner that the tip of the electronic pen 11 is actually written on the writing surface of the liquid crystal panel 13.

(A) Display of virtual sticky note and initial setting of its pasting area Next, in the virtual sticky note input display system S of the present embodiment, a display example on the display device 3 of the virtual sticky note application processed by the server 2 As shown in FIG. In the example shown in the figure, the user of the writing panel 1 creates and pastes six virtual sticky notes 301 to 306 at arbitrary positions in the display area coordinates Xs-Ys of the display device 3. Note that the two virtual sticky notes 301 and 302, the two virtual sticky notes 303 and 304, and the two virtual sticky notes 305 and 306 are created by different users, and each virtual sticky note is created and used. Different colors are displayed for each person, that is, for each terminal ID. Each of the virtual sticky notes 301 to 306 is formed in a rectangular shape having an appropriately adjusted size, and document information expressed by stroke data input by writing on the writing panel 1 (in the figure, all “ "..." is abbreviated). This document information may be entered as a normal character string consisting of a plurality of characters, or in addition to this, a figure or the like arbitrarily written by the user may be entered as it is.

  By using such a virtual sticky note application, the user can temporarily display fragmented document information on the display screen of the display device 3 in a free writing manner by handwriting input. According to the virtual sticky note input / display system S configured in this way, a plurality of users display virtual sticky notes 301 to 306 describing their ideas on the display device 3, and study work based on a common theme It can be used for so-called brainstorming.

  FIG. 7 shows an example of handwriting input of stroke data to the writing panel 1, and the illustrated coordinate area Xt-Yt of the writing panel 1 corresponds to the effective coordinate area of the coil sheet 100 of FIG. . Stroke data (character string of “Aiueo” in the example shown) written in the entry coordinate area Xt-Yt is cut out by enclosing it in a rectangular frame in units of characters, as shown in the figure. Converted to character image data such as format. In the illustrated example, one character is divided corresponding to one character image data. However, the present invention is not limited to this, and depending on the method of surrounding the rectangular frame, a plurality of characters are made to correspond to one character image data. You may divide as follows. That is, one character image data is divided and converted not in stroke units but in character units. A character image data string in which the plurality of character image data are arranged in the order of entry is written on the virtual sticky note paper. In the following description, it is assumed that stroke data is also written on the virtual sticky note paper.

  Further, in this example, as shown in FIG. 8, the reference position of the sticky reference position of the sticky area of the virtual sticky note in the display area coordinates Xs-Ys is the coordinate position of the upper left vertex of each virtual sticky note. (P, q), and the sticky note coordinates Xf-Yf with the sticking reference position (p, q) as the origin are set in the sticking region of the virtual sticky note. The stroke data entered on the virtual sticky note is the same as the character image data of the character image data string from the position near the sticking reference position (p, q) on the sticky note coordinates Xf-Yf of the virtual sticky note. They are arranged at intervals and displayed at the same predetermined display magnification. The predetermined display magnification is set to a magnification for enlarging and reducing each character image data input on the entry coordinate area Xt-Yt of the writing panel to a size that is easily viewable on the display area coordinates Xs-Ys. This is uniformly applied to all character image data written and displayed on the same virtual sticky note.

  In the case of Japanese notation, there are vertical writing modes other than horizontal writing as shown in the figure, but the difference between these writing modes is that the horizontal writing direction is the right direction and the vertical writing mode The list direction is distinguished as the downward direction. Here, as described above, the stroke data itself written by the user on the writing panel 1 is composed of a set of position information of the electronic pen 11 detected on the entry coordinate area Xt-Yt. The direction of listing can be easily determined.

  In addition, when the number of character image data, that is, the number of characters written on the virtual sticky note is so long that the list length when they are arranged at a predetermined interval becomes unnaturally long, a line feed is appropriately performed to form a plurality of lines. Fill in and display. At this time, when the listing direction is the right direction as in the example shown in the drawing, that is, when the writing mode is horizontal writing, the line feed direction is downward. Further, when the line-up direction is the downward direction, that is, in the case of the vertical line-up form, the line feed direction is the left direction (in the case of vertical writing, see FIG. 14 described later). By such a line feed, the length of the virtual sticky note in the list direction is set within a predetermined initial length set in advance. It should be noted that the above enumeration direction and line feed direction correspond to the predetermined determination direction described in each claim.

  As described above, the character image data are arranged at equal intervals in the list direction at the same display magnification while appropriately performing line feed in the line feed direction on the sticky note coordinates Xf-Yf of the virtual sticky note, and further, vertically, horizontally By providing margins at predetermined intervals on each edge, the pasting area of the entire virtual sticky note in which the character image data string is written is initially set. At this time, when the horizontal width of the pasting area is W and the vertical height is H, in the case of the horizontal writing shown in the figure, the coordinate position (p + W, q + H) in the display area coordinates Xs-Ys, that is, the pasting area The coordinate position of the lower right vertex is the pasting region end point position (p + W, q + H) of the pasting region.

  When a virtual sticky note is newly created and pasted and displayed, the pasting area (hereinafter referred to as a new pasting area) is initially set as described above. In the present embodiment, this initial setting is performed. When the new pasting area overlaps with the pasting area of other existing virtual sticky note paper (hereinafter referred to as the existing pasting area), the new pasting area is deformed. Hereinafter, details of the deformation method will be described in order.

(B) Deformation method when overlapping with pasting area duplication determination When a user creates a new virtual sticky note, the pasting standard is first used by using an appropriate pointing device (not shown) such as a mouse. The position (p, q) is designated as an arbitrary position in the display area coordinates Xs-Ys. At this time, in order to avoid duplication of virtual sticky notes, it is assumed that the sticking reference position (p, q) is always specified within a range that is vacant outside the pasting area of the existing virtual sticky notes. Further, the position specification of the sticking reference position (p, q) may be performed by moving the electronic pen 11 while maintaining the pen-up state.

  Next, the stroke data written on the writing panel 1 is transmitted to the server 2. The server 2 converts the received stroke data into a character image data string, and initially sets a new pasting area of a virtual sticky note that can be displayed by listing the character image data string by the processing described above.

  Here, as shown in FIG. 9 (a), if the initial setting new pasting area located at the pasting reference position (p, q) does not overlap with any of the other existing pasting areas, there is no problem. A new virtual sticky note in which the stroke data is listed in the new pasting area can be pasted and displayed as it is. In FIG. 9 and subsequent figures, the character image data listed on the virtual sticky note is represented by a normal text font to avoid the complexity of illustration.

  On the other hand, as shown in FIG. 9B, when the initial setting new pasting area located at the pasting reference position (p, q) partially overlaps with any of the other existing pasting areas. When the new virtual sticky note is pasted and displayed as it is, the stroke data listed on the existing virtual sticky note on the overlapped side is covered with the new virtual sticky note and cannot be seen. In the present embodiment, the new pasting area is appropriately deformed in order to avoid such a decrease in visibility due to duplication. In the present embodiment, this duplication determination is made only at the duplications at the end edges (in the illustrated horizontal writing example, the right edge and the lower edge) in the list direction and the line feed direction in the new pasting area. Pay attention. Further, as described above, the direction of line listing and the direction of line feed are determined by the horizontal writing mode and vertical writing mode of stroke data.

  Further, even when the overlap is determined, as shown in FIG. 9B, only the edge (right edge in the example shown) of either the list direction or the line feed direction in the new pasting area is present. If they overlap, there is a possibility that the new pasting area can be transformed and pasted. However, as shown in FIG. 9 (c), when overlapping at the end edges (in the illustrated example, the right edge and the lower edge) in both the list direction and the line feed direction in the new pasting area In this embodiment, since the paste display that avoids duplication cannot be performed no matter how the new paste area is deformed, the paste display itself is regarded as impossible.

  If only the end edge of either the list direction or line feed direction overlaps, the new pasting area is deformed by the following method. First, as shown in FIG. 10, the edge of the existing pasting area that is located closest to the pasting position and the line feed direction from the position of the pasting reference position (p, q) in the display area coordinates Xs-Ys. The separation distance to the part is detected. At this time, the separation distance is detected in both the list direction and the line feed direction regardless of the presence or absence of overlap. Moreover, the edge of the object for which the separation distance is detected is an edge at a position that may overlap with the edge of the end in both the list direction and the line feed direction in the new pasting area. That is, the edge located in the reverse direction (left direction in the case of horizontal writing shown in the figure) or the reverse direction of the line feed direction (upward direction in the case of horizontal writing shown) from the reference reference position (p, q) In addition, the edge that is far apart compared to the size of the pasting area of the normal virtual sticky note paper does not have to be a detection target of the separation distance. And this separation distance detects the separation distance between the sticking reference position (p, q) and the extension line of the edge to be detected. When there is no existing pasting area in a direction in which no overlap is determined, the separation distance to the edge of the display area coordinates Xs-Ys is detected.

  Then, if the default new pasting area and the existing pasting area overlap in the list direction, as shown in FIG. 11, character image data is arranged in the list direction one character at a time in the order of entry, and one line of list is displayed. The length is adjusted so as to be within the detected separation distance in the list direction. At this time, it is preferable to adjust so as to include the margins at both ends in the row direction. In this way, each time the column length for one line is adjusted, the line feed in the line feed direction is repeated, and the new pasting area is deformed so that all character image data can be arranged. Here, as shown in FIG. 12, when the length of the newly pasted area as a result of the deformation in the line feed direction (height H in the case of horizontal writing in the illustrated example) exceeds the detected separation distance in the line feed direction. Notifies that the pasting display error of the new virtual sticky note is impossible, and notifies the pasting display error.

  If the default new pasting area and the existing pasting area overlap in the line feed direction, as shown in FIG. 13, the detected separation distance in the line feed direction is set to the length of the character image data in the line feed direction ( The number of rows that can be arranged (2 rows in the example shown) is calculated by dividing by the height in the case of horizontal writing shown in the drawing. At this time, it is preferable to calculate so as to include the margins at both ends in the line feed direction. The number of character image data, that is, the number of written characters (9 characters in the example shown) is divided by the number of lines that can be arranged in this way, and the number of characters listed in each row (4 characters or 5 characters in the example shown) is calculated. To do. Then, with the calculated number of characters written in each matrix, the character image data is arranged in the row direction in order from the first line, and the new pasting area is deformed so that all the character image data can be arranged. Further, even in the case of the overlap in the line feed direction, the same determination as in FIG. 12 is performed. In other words, if the length of the newly pasted area as a result of deformation exceeds the separation distance in the detected list direction, it is assumed that the pasting display of the new virtual sticky note itself is impossible. An error is reported (in this case, not specifically shown).

  In addition, although the deformation | transformation of the example shown in the said FIGS. 11-13 was all the case where stroke data was horizontal writing, even in the case of vertical writing, it is the same by setting the list direction to the downward direction and the line feed direction to the left direction. The new pasting area can be transformed by this method. In this case, as shown in FIG. 14, the upper right vertex of the pasting area in the display area coordinates Xs-Ys is the pasting reference position (p, q), and each character image data of the character image data string from this neighboring position. Are arranged at equal intervals in the list direction (downward), and are displayed at the same predetermined display magnification. The coordinate position (p−W, q + H) in the display area coordinates Xs−Ys, that is, the coordinate position of the lower left vertex of the pasting area becomes the pasting area end position (p−W, q + H) of the pasting area. When the new pasting area overlaps with the existing pasting area in the list direction, it can be transformed as shown in FIG. 14A, and when the new pasting area overlaps with the existing pasting area in the line feed direction, FIG. ) As shown in FIG.

(C) Control processing of this embodiment In order to realize the functions as described above, the contents of the control processing performed by the CPU (not shown in particular) which is the control means of the server 2 will be described in order with reference to FIG. To do.

  In FIG. 15, the processing of the CPU of the server 2 shown in this flow has received an instruction to create a new virtual sticky note from the writing panel 1, for example, when operated by any user of the writing panel 1. To be started. First, in step SS5, the CPU acquires the reference paste position (p, q) at the display area coordinates Xs-Ys from the writing panel 1.

  Then, the process proceeds to step SS10, and the CPU continues to acquire stroke data from the writing panel 1.

  Then, the process proceeds to step SS15, and the CPU converts the stroke data acquired in step SS10 into a character image data string.

  Then, the process proceeds to step SS20, and the CPU determines the listing direction based on the position information of the plurality of electronic pens 11 included in the stroke data acquired in step SS10.

  Then, the process proceeds to step SS25, and the CPU is based on the pasting reference position (p, q) acquired in step SS5, the character image data string converted in step SS15, and the list direction determined in step SS20. A new pasting area at the display area coordinates Xs-Ys is initially set.

  Then, the process proceeds to step SS30, and the CPU determines whether or not the initial new pasting area set in step SS25 overlaps with another existing pasting area. If the initial new pasting area does not overlap any existing pasting area, the determination is not satisfied and the routine goes to Step SS75. On the other hand, if the initial new pasting area overlaps with any existing pasting area, the determination is satisfied, and the routine goes to Step SS35.

  In step SS35, the CPU determines whether or not the overlap determined in step SS30 is overlapped in two directions, that is, the list direction and the line feed direction. If the initial new pasting area overlaps with the existing pasting area in two directions, the determination is satisfied, and the routine goes to Step SS40.

  In step SS40, the CPU regards that the pasting display for avoiding duplication is not possible no matter how the new pasting area is deformed, and displays on the display screen of the display device 3 or transmits a notification signal to the writing panel 1. Then, a pasting display error is notified. Then, this flow ends.

  On the other hand, if it is determined in step SS35 that the initial new pasting area overlaps with the existing pasting area in only one direction, the determination is not satisfied and the process proceeds to step SS45.

  In step SS45, the CPU determines whether the listing direction determined in step SS20 is the right direction, in other words, whether it is horizontal writing. If the listing direction is horizontal writing in the right direction, the determination is satisfied, and the routine goes to Step SS50.

  In step SS50, the CPU detects the separation distances in the right direction and the downward direction from the reference reference position (p, q) acquired in step SS5, that is, the separation distances in the list direction and the line feed direction.

  Then, the process proceeds to step SS55, and the CPU performs the above-described method (B) based on the separation distances in the list direction and the line feed direction detected in step SS50 and the character image data string converted in step SS15. Deform the new pasting area. Then, the process proceeds to step SS70.

  On the other hand, in the determination in step SS45, if the listing direction is vertical writing in the downward direction, the determination is not satisfied and the process proceeds to step SS60.

  In step SS60, the CPU detects a separation distance in the downward direction and the left direction from the reference reference position (p, q) acquired in step SS5, that is, a separation distance in each of the list direction and the line feed direction.

  Then, the process proceeds to step SS65, and the CPU performs the above-described method (B) based on the separation distances in the list direction and the line feed direction detected in step SS60 and the character image data string converted in step SS15. Deform the new pasting area. Then, the process proceeds to step SS70.

  In step SS70, the CPU determines whether or not the new pasting area deformed in step SS55 or step SS65 overlaps with another existing pasting area. If the deformed new pasting area overlaps with any existing pasting area, the determination is satisfied, and the process proceeds to step SS40 to perform the same procedure.

  On the other hand, if the new pasted area after deformation does not overlap any existing pasted area, the determination is not satisfied and the routine goes to Step SS75.

  In step SS75, the CPU performs a line feed in the line feed direction as appropriate in the new pasting area at that time, and creates a new virtual sticky note in which each character image data is entered and displayed at the same display magnification at equal intervals in the list direction. Paste display. Then, this flow ends.

  In the above, the procedure of step SS5 in the flow of FIG. 15 corresponds to the paste reference position acquisition means and the paste reference position acquisition procedure described in each claim, and the procedure of step SS10 is the stroke data acquisition means and the stroke data acquisition procedure. The procedure of step SS15 and step SS20 corresponds to the data conversion means and the data conversion procedure, the procedure of step SS25 corresponds to the initial area setting means and the initial area setting procedure, and the procedure of step SS30 is the duplication determination means and duplication It corresponds to the determination procedure, the procedure of Step SS50 and Step SS60 corresponds to the separation distance detection means and the separation distance detection procedure, the procedure of Step SS55 and Step SS65 corresponds to the pasting area changing means and the pasting area change procedure, Step SS70 And the procedure of step SS75 is newly pasted It corresponds to a unit and a new patch procedures. Further, the procedure of step SS20 corresponds to the listing direction determining means.

  As described above, in the server 2 provided in the virtual sticky note input / display system S of the present embodiment, the direction of listing from the pasting reference position (p, q) to the existing pasting area by the procedure of Step SS50 and Step SS60. And the separation distance in the line feed direction is detected. Further, the procedure of Step SS55 and Step SS65 is based on the detected separation distance so that the new pasting area does not overlap with the existing pasting area in the list direction and the line feed direction when the new pasting area is located at the pasting reference position (p, q). Change the size of the new pasting area. Then, the procedure of step SS70 and step SS75 determines whether or not all the character image data in the character image data sequence can be listed at a predetermined display magnification with the changed size of the new pasting area. If so, a new virtual sticky note is pasted and displayed in the new pasting area at the pasting reference position (p, q).

  As a result, in the present embodiment, a new virtual sticky note can be pasted and displayed at the reference position designated by the user while maintaining the display magnification of the character image data string without overlapping with the existing virtual sticky note. As a result, it is possible to create a virtual sticky note with a high degree of freedom by avoiding complicated display of the virtual sticky note.

  In the present embodiment, in particular, the procedure of step SS20 determines whether the list direction of the character image data is the right direction in the case of horizontal writing or the downward direction in the case of vertical writing. In the procedure of step SS25, the character image data is arranged with a line feed in the line feed direction corresponding to the row direction so that the row length of the character image data row in the row direction falls within a predetermined initial length. In this way, the size when all the character image data is arranged in the row direction and the line feed direction is set as the initial size of the new pasting area. As a result, a new virtual sticky note can be initially set in a natural rectangular shape, and it is easy to specify a position that assumes the shape even when the user specifies the sticking reference position (p, q). .

  In the present embodiment, in particular, the procedure of step SS50 and step SS60 detects the separation distance in both the listing direction and the line feed direction from the pasting reference position (p, q). As a result, it is possible to detect a separation distance appropriately corresponding to the case where the character image data string is written horizontally or vertically.

  In the above embodiment, each character image data corresponds to one character, and the example in which the list and line feed in the pasting area are performed in units of this character image data is shown. However, the present invention is not limited to this. Absent. For example, as shown in FIG. 16, the initial new pasting area in which the character image data string of the sentence example “Today is good weather” is entered is the edge of the existing pasting area between “heaven” and “ki”. Consider the case of overlapping. At this time, if the new pasting area is changed so that each character image data is made to correspond to one character as in the above embodiment, a line break is performed between “heaven” and “ki”. The text is displayed unnaturally. However, when a plurality of continuous character image data constituting one phrase such as “today”, “good”, and “weather” in the illustrated sentence example are newly collected as one character image data A line break is made between “good” and “weather”.

  In the procedure of step SS15 of the above-described embodiment, the character image data may be converted so as to be grouped into phrases as described above. In this case, a plurality of characters constituting one phrase at a line break in the character image data string. Since the image data is not separated, the character image data string can be read with a natural line break.
