DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, transmitting data such as characters and figures manually input by a participant in a conference to a coordinate data input device in a conference room located at a plurality of remote locations. The present invention relates to a handwritten input data display system used for displaying on a display device arranged in each conference room, and a coordinate data input device, a display device, and a handwritten input data display device used for the system.

[0002]

2. Description of the Related Art FIG. 19 shows a conventional configuration example of a handwritten input data display system. For example, a presentation device that connects a personal computer (personal computer) 1 and a display device 2 is installed in each conference room, and the personal computer 1 in each conference room can communicate via a telephone line or the like. The display device 2 includes, for example, a projector 3 and a display board 4 having a pressure-sensitive touch sensor.

When a conference or the like is held between conference rooms at remote locations, the personal computer 1 is operated in any one of the conference rooms, and data handled inside the personal computer 1 or stored in an external storage device. Data and the like are projected and displayed on the display board 4 by the projector 3, and the same data is transmitted to the personal computer 1 in another conference room via a telephone line, and the same contents are also displayed on the display board 4 of the conference room. Display. In this way, the participants in each conference room hold a conference or a discussion while watching the same display contents on the display board 4.

In this case, for example, when the presenter supplements the content currently displayed on the display board 4, if a character or a figure is drawn on the surface of the display board 4 using the writing implement 5, the writing pressure Is detected by the pressure-sensitive touch sensor, and input coordinate data is obtained. The input coordinate data is transmitted to the personal computer 1, and is also transmitted to the personal computers 1 in other conference rooms via the telephone line. Then, characters, figures, and the like added by the presenter are similarly projected on the display boards 4 in the conference rooms in various places.

[0005]

However, in such a conventional presentation apparatus, since the projector 3 draws characters and figures on the display board 4 on which the display contents are projected, the contents to be additionally displayed are added to the contents being projected and displayed. When they overlap, the screen becomes difficult to see. Furthermore, if the content added to the display board 4 is also projected in another conference room, it may not be clear which display content was input by whom. In addition, when the display areas of the contents overlap, there is a problem that the screen becomes more difficult to see.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a handwritten input data display system capable of displaying characters, figures, and the like, which are input by handwriting by each user, in an easily viewable state on a display device. And a coordinate data input device, a display device, and a handwritten input data display device used in the system.

[0007]

To achieve the above object, a handwritten input data display system according to claim 1 is provided.
Coordinate data acquisition means for acquiring data input by handwriting as coordinate data, control means for processing and controlling the coordinate data acquired by the coordinate data acquisition means,
A plurality of coordinate data input devices including a communication unit for transmitting the coordinate data, a communication unit for receiving the coordinate data transmitted from the plurality of coordinate data input devices, and a communication unit via the communication unit. It is constituted by one or more display devices comprising control means for processing and controlling the received coordinate data, and display means for displaying characters, figures, etc., which are input by hand based on the coordinate data. Wherein the control means of the coordinate data input device controls transmission of the coordinate data acquired by the coordinate data acquisition means with ID information of the coordinate data input device attached thereto, and control of the display device. The means is a character or the like based on the coordinate data received via the communication means,
It is characterized in that control is performed such that ID information attached to the coordinate data is displayed on the display means.

[0008] For example, it is assumed that the handwritten input data display system of the present invention is applied to a case where a participant holds a conference in a state where the participants are dispersed in conference rooms at a plurality of remote locations. Place a coordinate data input device near each participant in the meeting, and if there are any considerations or opinions at the meeting,
The participant inputs those items and the like by hand into the coordinate data input device. Then, the characters and the like input by handwriting in each coordinate data input device are converted into coordinate data, transmitted to the display device together with the ID information of the coordinate data input device, and displayed on the display means.

[0009] That is, a participant who sees characters and the like displayed on the display means can determine which opinion is input by whom by referring to the ID information. Even when a conference is to be held, it is easy for each participant to communicate. In addition, the control unit of the display device can also know from which coordinate data input device the coordinate data is transmitted based on the ID information.
For example, it is possible to display an area separately for each coordinate data input device. Therefore, the display device can display the display means in a form that makes it easier for the user to see.

A handwritten input data display system according to claim 2, wherein said display device includes storage means for storing data received via said communication means, and said control means of said display device is provided with said communication means. The data received via the storage unit is stored in the storage unit, and when there is a display request from the user, the display unit of the display unit is divided into a plurality of regions by referring to the ID information of the coordinate data stored in the storage unit. Characters and the like input in each coordinate data input device are displayed in different areas, and at the same time, the characters and the like that are assumed to have been input substantially at the same time are simultaneously displayed.

That is, in the above-described example of the conference, when the progress of the conference has been completed or when the conference is over, if the user wants to check the considerations and opinions taken during the conference, the user displays the message. When a display request is given to the device, the control means reads out the handwritten input data stored in the storage means and causes the display means to display it again (playback).

At this time, the control means displays the characters and the like input in each coordinate data input device in different areas, so that the display is performed in a state where the user can easily understand the opinions and the like of the participants. In addition, the control unit of the display device simultaneously displays the characters and the like estimated to have been input substantially at the same time, so that the user can easily grasp the progress of the meeting even during playback. .

According to a third aspect of the present invention, the control means of the coordinate data input device includes:
The control unit controls the coordinate data acquired by the coordinate data acquiring unit to be transmitted with the input time data of the data attached thereto, and the control unit of the display device stores the input time data in the storage unit when there is a display request from a user. The input time is estimated by referring to the input time data of the stored coordinate data. That is, a character or the like input by handwriting is a set of a plurality of drawing lines, and each of the drawing lines can be regarded as a set of coordinate data from a writing start point to a writing end point (referred to as one stroke).

The time when the control means of the coordinate data input device recognizes the writing start point as an input start time,
If the time recognized as the writing end point is transmitted to the display device side as the input end time, the control means of the display device considers the average human handwriting input operation time, and determines the input start time of a certain stroke and one of the stroke start time. By successively comparing the input end time of the previous stroke with the input end time of the previous stroke, it is determined whether a chain (group) of a plurality of strokes belongs to the input time zone of the same period (for example, 1
It is possible to determine whether the sentence is a series of sentences input to express one opinion. Further, after performing the above-described analysis on the coordinate data of each coordinate data input device, if the input start times at the beginning of each stroke group are compared among the plurality of coordinate data input devices, they are input at substantially the same time. It is possible to estimate whether or not the opinion is given.

As described above, not only the input start time is compared for each stroke group to estimate the input timing, but the input timing may be similarly estimated for each stroke. That is, the control unit of the display device displays each stroke according to the time difference based on the input start time of each stroke from a certain reference time during playback, so that each user can actually input handwriting. It is also possible to display characters and the like at the same timing as the timing of the operation.

According to the fourth aspect of the present invention, the control means of the display device causes the display means to display the input time data. Etc. can be grasped at what point in the meeting was input.

According to a fifth aspect of the present invention, the control means of the display device estimates the input time based on the coordinate data of each coordinate data input device. For example, when a text is line feed, the input coordinate position changes greatly. Also, a series of sentences input at a certain time is described in a relatively close position even if it extends over a plurality of lines, but the position of a sentence first input at the next time is input at the previous time. The description starts from a position relatively far from the position of the last sentence. Therefore, it is possible to classify each stroke into a certain input time group based on, for example, the maximum value or the minimum value of the coordinate data of each stroke, and estimate the input time.

According to the handwritten input data display system of the sixth aspect, the control means of the display device is configured to, for each step of a display request from a user, display the character or the like which is estimated to have been input substantially at the same time. Since the content is sequentially displayed in each display area of the display means, when the display content is played back, the user can sequentially refer to each content according to, for example, the progress of the conference.

According to the handwriting input data display system of the present invention, the coordinate data input device includes information input means for a user to input display information, and the control means of the coordinate data input device includes: The display information input by the information input means is added to the ID information. For example,
When each participant of the conference inputs his / her name as display information, the information is added to the ID information and transmitted to the display device. Then, when each opinion is displayed on the display device side, the name of the participant who input the opinion is also displayed, so that each participant can more clearly grasp who input each opinion. become able to.

According to the handwriting input data display system of the present invention, the control means of the display device divides the display area of the display means according to the number of types of ID information transmitted from each coordinate data input device. Therefore, the display area is set according to the number of coordinate data input devices that actually transmitted the coordinate data. Therefore, even if the display area is connected via the communication means, the display area of the coordinate data input device in which no handwriting input is performed is not wastefully secured, and the display area is effectively used.

According to the handwritten input data display system of the ninth aspect, the control means of the coordinate data input device controls the data to be sequentially transmitted each time the coordinate data is obtained by the coordinate data obtaining means, and displays the data. The control means of the device displays characters and the like on the display means in real time based on the data sequentially transmitted from the coordinate data input device. That is, the coordinate data input device sequentially transmits the coordinate data one stroke at a time, so that the control means of the display device displays each stroke data in the order in which the stroke data is received. Is displayed with. Therefore, the response of the display to the handwriting input is improved.

According to a tenth aspect of the present invention, in the handwriting input data display system, the control means of the coordinate data input device, when a user designates a specific position display, inputs the coordinate data obtained by the coordinate data obtaining means. Is transmitted with the designation of the specific position display, and the control means of the display device transmits the ID for characters based on the coordinate data with the designation of the specific position display.
Regardless of the information, it is displayed in a specific display area of the display means.

For example, when the user wants to display the title of the meeting, the time, the date, etc. comprehensively at the top of the display means, the user inputs and specifies the specific position display. The control means of the display device causes the coordinate data accompanied by the designation to be displayed in a specific display area such as the top of the display means. Therefore, a title or the like is displayed at an appropriate position.

According to the handwriting input data display system of the present invention, the control means of the coordinate data input device may be configured such that, when a user inputs a designation for permitting an overwrite display of a character or the like on the display means of the display device, The coordinate data acquired by the coordinate data acquiring means is controlled so as to be transmitted with the overwrite permission designation added thereto, and the control means of the display device controls the character data based on the coordinate data with the overwrite permission designation attached. Enables overwrite display over any of a plurality of display areas in the display means.

That is, for a description item that is preferably displayed not only in its own display area but also in another display area, the overwriting permission is specified on the coordinate data input apparatus side, so that the display apparatus side Is processed so as to overwrite and display over any of a plurality of display areas.

According to the twelfth aspect of the present invention, the control means of the coordinate data input device is used to input handwritten data to the coordinate data input device and can transmit its own ID information. When handwritten data is input by the data input unit configured as described above, when ID information of the data input unit is received,
The coordinate data acquired by the coordinate data acquisition means is controlled to be transmitted with the ID information of the data input means attached thereto, and the control means of the display device controls the data to which the ID information of the data input means is attached. Is characterized in that a display mode on the display means is controlled according to the ID information.

That is, when the data input means used to input handwritten data is configured to be able to transmit its own ID information, the ID information of the data input means is:

The surfaces are connected so that they can be opened and closed. Then, normally, the display unit 12 is used with the display surface thereof opened.

FIG. 1 schematically shows an electrical configuration of the input display board 10. The stroke data input unit (coordinate data acquisition means, control means) 31 is, for example,
CPU, memory such as ROM and RAM, multiplexer for switching signal output from coil 25, amplifier for signal amplification, A / D converter and FSK signal demodulation circuit, real-time clock (RTC) IC for time data acquisition
It is comprised including.

The transmitting section (communication means) 32 transmits the coordinate data acquired by the stroke data input section 31 to another input display board 10 via its own receiving section (communication means) 33 and the communication line 13. Communication interface. In addition, the receiving unit 33 has its own transmitting unit 32.
And a communication interface for receiving data transmitted from another input display board 10. Receiver 33
The received data is written and stored in the stroke data storage unit (storage means) 34.

The synchronous display control unit (control means) 35 causes the display unit 12 to display characters and the like based on the coordinate data received by the receiving unit 33 and stored in the stroke data storage unit 34 in real time, or to temporarily input data. When the display request is given by the user after the end of the process, a playback process for displaying the coordinate data stored in the stroke data storage unit 34 again is performed. Note that audio and the like in the conference are transmitted between the conference rooms using separate transmission / reception systems (communication lines may be shared).

Next, the operation of this embodiment will be described with reference to FIGS. FIG. 6 shows that the user
5 is a flowchart showing the processing performed by the stroke data input unit 31 when attempting to draw a character or the like on the writing sheet 19 of the coordinate data input unit 11 by using FIG. As described above, when the user presses the pen tip 27 of the pen 15 on the writing sheet 19, the internal switch 30 is turned on, and the coil 25 generates an alternating magnetic field (FSK modulation signal).

Then, the stroke data input unit 31
It is determined that handwriting input has started by receiving the alternating magnetic field (step A1, "YES"), and input start time data (time stamp) is obtained from the RTC (step A2). Also, the FSK transmitted by the pen 15
The ID information of the pen 15 and the coordinate data of the input start point are obtained based on the demodulation level of the modulation signal (step A).
3, A4).

Hereinafter, an outline of a process regarding acquisition of coordinate data will be described. FIG. 7 shows a case where the user touches the pen 15 at the point Ps on the writing sheet 19 of the coordinate data input unit 11, draws one line L, and releases the pen 15 at the point Pe. An example of a series of coordinate data (these operations are referred to as one stroke) is shown.

When an alternating magnetic field generated by the pen 15 is magnetically coupled to the coil 25 of the coordinate data input unit 11, a voltage signal is induced on the coil 25 side. Then, the stroke data input unit 31 of the coordinate data input unit 11 performs A / D conversion on the level of the voltage signal induced in the X coils (X1, X2,. Then, the level is stored in the memory, and the X coordinate data is determined by the position of the X coil indicating the highest level among them. Subsequently, the stroke data input unit 31
Similarly, for the Y coil (Y1, Y2,..., Yn) of the coil 25, the level of the induced voltage signal is A / D converted and scanned so as to be sequentially read to determine the Y coordinate data. Then, one piece of coordinate data (X, Y) is obtained.

When the coordinate data of the input start point Ps is obtained as (xs, ys) as described above, the stroke data input unit 31 determines whether or not the handwriting input has been completed (step A5). . That is, when the user releases the pen tip 27 of the pen 15 from above the writing sheet 19, the internal switch 3
Since 0 is turned off and the output of the alternating magnetic field stops, it is determined whether or not the magnetic field signal is detected. If the handwriting input has not been completed ("NO"), the process waits until the next sampling cycle is reached (step A).
6, "YES") The process proceeds to step A4 to obtain the next coordinate data (x1, y1).

Then, as shown in FIG. 7A, Ps,
The coordinate data of P1, P2,...
If it is determined that the handwriting input has been completed in e (step A5, "YES"), the point Pe is set as the input end point, and the input end time data is obtained again by referring to the RTC (step A7). That is, the so-called one-stroke data from the input start point Ps to the input end point Pe corresponds to one stroke. For example, when the character "A" is input by handwriting, a stroke of three strokes is usually input.

Then, the stroke data input unit 31
Is attached with the ID (board ID) of the coordinate data input unit 11, the ID (pen attribute) of the pen 15, and the input start time data at the beginning of one stroke data, and the input end time data at the end. When the packet is created and output to the transmission unit 32, the process returns to step A1 and waits for the start of input of the next stroke.

The transmission unit 32, which has received the data packet output by the stroke data input unit 31, outputs a data transmission request to itself and the reception unit 33 of the other input display board 10, and the other device 10 performs communication. After confirming that the operation has not been performed, a data packet for one stroke is transmitted.

Next, FIG. 8 is a flowchart showing the contents of processing on the display unit 10 side. First, the receiving unit 33 sets Steps B1 to B5 as a fixed communication period, and receives data during that period. That is, when the communication period starts (step B1), it is checked whether a data transmission request has been issued from any of the transmission units 32 (step B2), and if the request has been issued (“YES”). 3.) Perform data reception processing (step B3). Then, the board ID attached to the received data is determined, and the received data is stored in a predetermined storage area in the stroke data storage unit 34 for each board ID (step B).
4). Then, the process proceeds to step B5 to determine whether or not the communication period has ended. If the communication period has not ended (“N
O ") The process proceeds to step B2 to wait for the next data transmission request.

When the communication period ends in step B5 ("YES"), the synchronous display control unit 35 determines how many board IDs of the data stored in the stroke data storage unit 34 exist, and determines the number. According to the display panel 12
The display area on the screen a is divided. For example, if the number of board IDs is “3”, as shown in FIG.
The display area is divided into three corresponding to (step B)
6). Then, characters and the like based on the respective coordinate data are displayed in a display area corresponding to each board ID (step B).
7). That is, in the case of the stroke data shown in FIG. 7, a character or a figure is drawn by drawing a straight line between two points such as point Ps-point P1, point P1-point P2,.

For example, the input display boards 10 (1), 10
If the handwritten input in (2) and 10 (3) is "ABCDEF", "12345", and "Aioe", respectively, respective characters and the like are displayed in the corresponding display areas of the display unit 12. . In this case, the board IDs of the input display boards 10 (1) to 10 (3) are displayed as "Board 1", "Board 2", and "Board 3" in each display area of the display panel 12a. , The person who looks at the display panel 12a,
It is possible to easily recognize which input display board 10 is a character string input.

Furthermore, based on the ID of the pen 15, for example, a display color associated with the pen (eg, black, blue, red, etc.) is appropriately set and a character string is displayed. At the end of each character string, the input start time is displayed at the same time. In FIG. 9, the input of the character strings "ABCDEF" and "12345" is started at 10:33, and the input of the character string "Aieo" is 10:34.
Indicates that input has started at minute.

Next, FIG. 10 is a flowchart of the playback process executed on the display unit 12 side. When the playback mode is selected by the user's operation, the process is started. First, the synchronous display control unit 35 reads the stroke data with one board ID from the stroke data storage unit 34 (Step C1). At this time, the board ID in which the earliest input start time is recorded
Is first selected and used as a reference for subsequent classification.

Next, the synchronous display control unit 35 estimates the input time with reference to the time stamp of each stroke data, and classifies the data into groups (step C2). Here, FIG.
Shows an example of a time chart when each stroke data is input. The input start time and the input end time of each of the stroke data “A” to “F” are compared for the input display board 10 (1). For convenience of explanation,
Stroke data for one character is shown collectively.

For example, the difference between the input end time of "A" and the input start time of "B" is t1, and the difference between the input end time of "B" and the input start time of "C" is t2. . If these time differences are, for example, less than 3 seconds, it is determined that these stroke data belong to the same group (estimated that they were input at the same time). That is, the character string “ABC”
Are classified as the first group. If the time difference t3 between the input end time of “C” and the input start time of “D” is 3 seconds or more, the character string “DEF” starting with “D” is classified into the second group.

When the classification process is performed as described above, it is determined whether or not the classification process has been performed for all board IDs. If all the board IDs have not been processed ("NO"), the process returns to step C1 to return to the next board ID. Is processed.

Referring again to FIG. Next, the input display board 10 (1) having the earliest input start time of the first stroke data next to the input display board 10 (1) is selected. In this case, for example, the input display board 1
Before 3 seconds from the input end time of the last stroke data of the first group at 0 (1), the input display board 10
If the first input start time of (2) has started, it is determined that the stroke data belongs to the same group. In this case, since the input start time of “1” is earlier than the input end time of “C”, the character string “12” starting from “1” is the second character.
Classified as a group.

Similarly, the time difference between the input start time of "A" on the input display board 10 (3) and the input end time of the last stroke data "2" of the first group on the input display board 10 (2). Since t5 is within 3 seconds, the same first
It is determined to belong to the group.

The input start time of “D” belonging to the second group on the input display board 10 (1) is the input end time of the last stroke data “i” of the first group on the input display board 10 (3). The character string "DEF" is input to the input display board 1
Also in the relationship with 0 (3), it is determined to belong to the second group. That is, even if the character string is once determined to belong to the second group in the determination of the input display board 10 (1) alone,
If the time difference t7 is less than 3 seconds, the character string “DEF” may be determined to belong to the first group.

As described above, when the classification processing is performed on all the board ID data (step C3, “YE
S)), the synchronous display control unit 35 determines whether or not there is a step display request from any of the input display boards 10 (step C4), and when there is a step display request (“YE”).
S "), each time the request is made, the stroke data subjected to the classification processing is displayed step by step in each display area one group at a time (step C5).

For example, as shown in FIG. 12A, when there is a first step display request, data “ABC”, “12”, and “Ai” belonging to the first group are displayed in each display area. Next, if there is a step display request, FIG.
As shown in FIG. 7, data “DEF”, “3” belonging to the second group
45 "and" Ueo "are additionally displayed. Then, whether or not there is no undisplayed stroke data (step C6," N
O ") until the end of the display process is selected (step C
7, "YES") Similar processing is continued. In this example, the display of the input start time is omitted.

As described above, according to the present embodiment, the stroke data input unit 31 of the input display board 10 uses the ID information of the input display board 10 in the coordinate data of the handwritten input characters and the like acquired by the coordinate data input unit 11. Is transmitted to each display unit 12 side, and the synchronous display control unit 35 of the display unit 12
In this configuration, characters based on the coordinate data received via the receiving unit 33 and ID information attached to the coordinate data are displayed in different areas of the display panel 12a.

That is, when a participant is in a conference room A,
In a case where a conference is held in a state of being distributed to B and C, each participant refers to each display area and ID information by looking at the display panel 12a to determine which opinion was input by whom. Can be determined. Therefore, even when the conference is proceeding in a state where the conference is dispersed in a remote place, it is easy for each participant to communicate. In such a case, the display panel 12 according to the number of board IDs transmitted from each input display board 10
Since the display area a is divided and set, the display area is set according to the number of input display boards 10 that have actually transmitted the coordinate data. Therefore, even if the input display board 10 is connected via the communication line 13, no handwriting input is performed.
Since the display area for is not wasted,
The display area of the display panel 12a can be effectively used.

Further, according to the present embodiment, the stroke data input unit 31 sequentially transmits data every time coordinate data is acquired, and the synchronous display control unit 35 is sequentially transmitted from the stroke data input unit 31. Since the characters and the like are displayed on the display panel 12a in real time based on the data, the characters and the like input by handwriting are displayed substantially in real time, and the responsiveness of the display to the input is improved.

In the present embodiment, the display is synchronized for each stroke group. However, the display may be synchronized for each stroke. That is, the synchronous display control unit 3
5 displays each stroke at the time of playback according to a time difference (relative time) based on the input start time of each stroke from a certain reference time,
Characters and the like can be displayed on the display panel 12a at the same timing as when each participant actually performs handwriting input during the conference (that is, similar to the above-described real-time display).

Further, according to the present embodiment, when the progress of the meeting is completed or the meeting is completed, if the user wants to confirm the considerations, opinions and the like handled in the meeting, a step display request is given. Then, the synchronous display control unit 35 performs a playback process of reading out the data stored in the stroke data storage unit 34 and displaying the data again on the display panel 12a.

Then, the stroke data input unit 31
Since the acquired coordinate data is transmitted with the input time data added thereto, the synchronous display control unit 35 estimates the input time of each coordinate data by referring to the input time data, and inputs the data at approximately the same time during playback. Characters and the like presumed to have been displayed are displayed at the same time. Therefore, the user
Even during playback, the progress and progress of the conference can be easily grasped. Further, since the input start time of each character string is also displayed, it is possible to more clearly know the passage of time.

The pen 15 used for inputting handwritten data to the coordinate data input unit 11 also has the ID
The information can be transmitted and the stroke data input unit 31
Receives the ID information of the pen 15, transmits it to the display unit 12 side, and the synchronous display control unit 35 sets the display color of the display panel according to the attribute of the pen 15, so that the display mode can be variously controlled. .

FIGS. 13 and 14 show a second embodiment of the present invention. Only parts different from the first embodiment will be described. Note that the configuration of the second embodiment is basically the same as that of the first embodiment, and the processing content of the synchronous display control unit 35 is different. In the first embodiment, in step C5 shown in FIG. 10, the input time of each data is estimated based on the input time data attached to the stroke data. However, in the second embodiment, as shown in FIG. In step C8 instead of C5, the input time is estimated based on the coordinate data.

For example, it is assumed that the input positions of the input character strings "ABC", "DEF", and "GHI" on the input display board 10 (1) are represented in the XY coordinate system as shown in FIG. In FIG. 14, ymin (1) and ymax (1) are the maximum and maximum values of the Y coordinate of the character string "ABC", respectively.
n (2) and ymax (2) are the maximum values of the Y coordinate of the character string “DEF”,
The maximum values ymin (3) and ymax (3) are the maximum value and the maximum value of the coordinates of the character string "GHI" Y.

Comparing these magnitude relations, since the character string “DEF” is input with a line break for the character string “ABC”, ymax (2) <ymin (1). Since the character string "GHI" is input with a new line for the character string "DEF", ymax (3) <ymin (2). Here, the difference d1 (= ymin (1) −
When ymax (2)) and d2 (= ymin (2) -ymax (3)) are calculated, since d1 is relatively small, even if the character string "DEF" has a line feed, the character string "ABC" Can be estimated to have been input at the same time. Since d2 is relatively large, the character string “GHI” is replaced with the character string “DE”.
It is not presumed that it was input at the same time as F ″.

In this case, the magnitude of the difference value for classifying whether or not the data has been inputted in the same period is calculated by performing a statistical process such as obtaining the same difference for all character string data and taking an average. It is desirable to make the above decision. In addition, in a case where handwriting input is performed only one line at a time at approximately the same time, even if the difference value is about d1, it may be estimated that the input time is different simply due to line feed.

As described above, according to the second embodiment, the synchronous display control unit 35 estimates the input time of each coordinate data based on the coordinate value of each stroke data, Estimated characters etc. are displayed at the same time. Therefore, the user can easily grasp the progress and progress of the conference even during the playback, as in the first embodiment.

FIG. 15 shows a third embodiment of the present invention. In the third embodiment, the coordinate data input unit 11 is provided with information input means for allowing a user to specify and input specific information to be displayed on the display panel 12a, for example, his / her name. For example, a key for designating and inputting display information is prepared on the operation unit 18, or soft keys for the designation input are prepared on the writing panel 14, and after operating these, a coordinate data input unit is prepared. At 11, the user's name is entered.

Then, the stroke data input unit 31
The data of that name is incorporated into the data packet together with the board ID and the like and transmitted to the display unit 12 side. Then, the synchronous display control unit 35 extracts the name data from the packet and displays it at the end of the character string as shown in FIG. That is, in the character string of the display area corresponding to each input display board 10, the names of the participants of the conference using each board 10 are attached such as "Komatsu", "waterfall", and "Oshima". Is displayed.

As described above, according to the third embodiment, when the user inputs his / her name on the coordinate data input unit 11, the data is transmitted to the display unit 12 together with the board ID, and the synchronous display control unit 35 Since the name data is extracted and displayed together with the character string on the display panel 12a, when displaying each opinion or the like in the conference, the name of the participant who input the opinion or the like is also displayed, so that each participant is displayed. Can more clearly grasp who input each opinion and the like.

FIG. 16 shows a fourth embodiment of the present invention. In the fourth embodiment, a software key is provided on the coordinate data input section 11 so that the user can input information desired to be displayed in a specific display area of the display panel 12a, for example, a title or date of a conference. here,
The specific display area is a display area prepared separately from the display area prepared for each input display board 10.

Then, after the designation input for the specific display area is made, the title and date input in the coordinate data input section 11 are incorporated into a data packet and transmitted to the display section 12 side. Then, the synchronous display control unit 35
Extracts those data and places them in a specific display area (for example, the top row) of the display panel 12a as shown in FIG.
For example, it is displayed as “Consideration items for XXX April 14”.

As described above, according to the fourth embodiment, the title and date of the conference are displayed at the top of the display panel 12a.
It can be displayed separately from the display area prepared corresponding to each input display board 10.

FIG. 17 shows a fifth embodiment of the present invention. The fifth embodiment is an example in which a pointing rod 36 for pointing a character or the like input by handwriting on the writing panel 14 of the input display board 10 is used. The pointing rod 36 basically has a configuration in which the pen tip and the ink cartridge are removed from the pen 15, and includes a battery, a coil for generating a magnetic field, and the like. Then, an FSK modulation signal based on the ID information indicating the preset stick is output to the coordinate data input unit 11. When the coordinate data input unit 11 demodulates the FSK modulated signal and determines that the signal is the pointing rod 36, the coordinate data input unit 11 performs the following process.

That is, as shown in FIG. 17 (a), the user using the input display board 10 (1) gives an instruction using the indicating rod 36 for the character string "ABCDEF" which has already been input with the pen 15. And In addition, writing panel 1
In the sheet 19 of No. 4, characters written with the ink of the pen 15 are shown. It is assumed that the user first designates the lower part of the character "A" by the tip of the pointer 36, and then moves the pointer 36 rightward in the figure to indicate the lower part of the character "D". .

The stroke data input unit 31 is used to
When the ID No. 6 is determined, the ID is set in the “pen attribute” area shown in FIG. 7B in the first embodiment, and the coordinate data of the designated position is transmitted to the display unit 12 as a packet. When the synchronous display control unit 35 of the display unit 12 receives the packet and determines that the data is the coordinates of the pointing position of the pointing rod 36, the cursor symbol "" is displayed at a position corresponding to the pointing position coordinates of the display panel 12a. ▲ ”is displayed (see FIG. 17B). Also, in this case, the trajectory of the movement of the pointing position of the pointing stick 36 from the character “A” to the character “D” is displayed by a line having a different color or a different thickness from the character.

Incidentally, the cursor "▲" and the line indicating the movement locus are indicated by the point that the tip of the pointing rod 36 is separated from the writing sheet 19,
The display may be erased when the transmission of the data packet relating to the pointing rod 36 from the coordinate data input unit 11 is stopped, or the display may be left as it is, even if the transmission of the packet is stopped. It may be deleted when it is done.

As described above, according to the fifth embodiment, by using the pointing rod 36 on the coordinate data input unit 11 side, the indicated position and the movement locus of the indicated position are displayed on the display panel 12a on the display unit 12 side. Since it is displayed, it is possible to proceed with the conference while indicating the characters and the like input by handwriting, and it is possible to convey the intentions of the participants in a more understandable manner.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. The form of communication between the devices 10 can be variously modified. For example, the input display board 10 may be arranged near the participants in the same conference room, and each may hold a conference while referring to the display panel 12a. In this case, the communication line does not need to pass through a public telephone line, and a LAN or a unique communication protocol may be adopted. When the coordinate data input device and the display device are integrally configured as in the first embodiment, FIG.
As shown in (1), the data output from the stroke data input unit 31 is directly stored in its own stroke data storage unit 34, and only the data transmitted from the other input display boards 10 is received via the reception unit 33. May be stored in the stroke data storage unit 34. In this case, the function of the stroke data input unit 31 and the synchronous display control unit 35
The input display board (handwritten input data display device) 37 may be configured to execute the functions described above with one CPU.

Further, the coordinate data input device and the display device may be configured separately. For example, the function of the display unit 12 may be provided to a personal computer. Alternatively, only one large display is prepared as the display unit 12 for the plurality of coordinate data input units 11, and the conference proceeds while viewing the characters and the like handwritten by each participant while viewing the common display. But it is good. Further, (the number of coordinate data input devices)>
(The number of display devices), or the magnitude relationship may be reversed. When a conference is held between conference rooms at a plurality of remote locations as in the first embodiment, and when there are a plurality of participants in each conference room, a common display is provided for each conference room. It may be arranged. Not only the display area corresponding to the input display board to which the data is actually transmitted, but also the display area is prepared in advance according to the number of input display boards connected and in a communicable state. You may do it. The estimation of the input time may be performed by combining the method based on the input time data in the first embodiment and the method based on the coordinate data in the second embodiment.

The coordinate data is not limited to the method of transmitting data for each stroke. If a transmission switch or the like is provided and the user turns on the transmission switch at the end of inputting a series of character strings, the series of characters is transmitted. The coordinate data of the columns may be transmitted together. By judging the ID (attribute) of the pen, a character or the like handwritten by a particular pen can be overwritten on the display area of another input display board beyond the display area of the input display board. May be. Further, as in the third embodiment, a soft key for designating permission of overwriting may be provided, and overwriting may be permitted when designation is performed by the soft key. In the first embodiment, the process of classifying each stroke data into each group is performed. When a step display request is generated by the user, the stroke data of each group is changed every time the stroke data belonging to one input board 10 is classified. You may make it display sequentially.

The communication period may be terminated by a user's input operation. Steps B1 to B5
The display unit 12 may sequentially display the received data on the display panel 12a without setting the communication period of the communication. In this case, the size of the display area corresponding to one input display board is determined in advance, and if the display area is insufficient, the display areas may be displayed in a superimposed manner using a so-called window display format. In the second embodiment, a line feed may be determined based on a large decrease in the X coordinate value of the stroke data. In the fifth embodiment, the movement trajectory of the indicator rod 36 may be displayed blinking or may be dynamically displayed as an afterimage. Alternatively, only the indicated position may be displayed without displaying the movement locus of the pointing rod 36.

According to the handwritten input data display system of the present invention, the control means of the coordinate data input device adds the display information input by the information input means to the ID information. If the user inputs his / her name as display information, the display device also displays the name of the participant who input the opinion or the like when each opinion or the like is displayed. Therefore, each participant can more clearly understand who input their opinions and the like.

According to the handwritten input data display system of the eighth aspect, the control means of the display device divides the display area according to the number of types of ID information transmitted from each coordinate data input device. A display area is set according to the number of coordinate data input devices that have transmitted the coordinate data. Therefore, the display area of the coordinate data input device in which no handwriting input is performed is not wastefully secured, and the display area is effectively used.

According to the handwritten input data display system of the ninth aspect, the control means of the coordinate data input device sequentially transmits data each time the coordinate data is acquired, and the control means of the display device inputs the coordinate data. Since characters and the like are displayed on the display means in real time based on the data sequentially transmitted from the device, the display response to handwriting input is improved.

According to the tenth aspect of the present invention, the control means of the coordinate data input device, when the user designates the specific position display, specifies the specific position display in the acquired coordinate data. And send it with
The control unit of the display device displays characters and the like based on the coordinate data designated to display the specific position in the specific display area regardless of the ID information. For example, when it is desired to display the time, date, and the like comprehensively, they can be displayed at appropriate positions that are easy to see.

According to the handwritten input data display system of the present invention, the control means of the coordinate data input device assigns an overwrite permission specification to the coordinate data when the user inputs a specification for permitting the overwrite display of characters and the like. Then, the control unit of the display device causes the characters or the like to which the overwrite permission designation is given to be overwritten and displayed over any one of the plurality of display areas. Accordingly, it is possible to overwrite and display not only the own display area but also the other display areas that are preferable to be overwritten.

According to the twelfth aspect of the present invention, when the handwriting data is input by the data inputting means, the control means of the coordinate data inputting device displays the ID information of the data inputting means in the coordinate data. The control unit of the display device transmits the ID of the data input unit.
With respect to the data to which information is added, a display mode on the display means is controlled according to the ID information. Therefore, for example, the display color is set to black for the coordinate data input by the data input unit of the ID information (attribute) A, and the display color is set to red for the coordinate data input by the data input unit of the ID information B. As described above, the display mode can be variously controlled.

According to the handwriting input data display system of the thirteenth aspect, since the coordinate data input device and the display device are integrally formed, the communication means of both can be connected internally in advance. Therefore, the user
The connection may be performed so that the coordinate data input device and the display device used by itself and those devices used by other users can communicate with each other, so that handling such as carrying and connection can be facilitated.

According to the handwriting input data display system of the present invention, the control means of the handwriting input data display device causes the display means to display characters and the like based on the coordinate data, and adds its own ID information to the coordinate data. Then, the data is transmitted to another handwritten input data display device, and characters and the like based on the coordinate data transmitted by the other handwritten input data display device and ID information attached to the coordinate data are displayed on the display means. Therefore, similar to the thirteenth aspect, the same effect as the first aspect can be obtained by configuring an integrated handwritten input data display device including the coordinate data acquisition means and the display means.
