Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing system using an electronic pen, and more particularly to a method for holding personal information in a handwriting input device.

[0002]

2. Description of the Related Art Generally, a handwriting input device using an electronic pen is composed of a main body having a display-integrated tablet and an electronic pen for instructing coordinates. The main body stores a handwritten character recognition dictionary, and converts the handwritten character to a character code by comparing the writing pattern of the character input with the electronic pen and the standard writing pattern registered in the handwritten character recognition dictionary. The recognition process is being performed.

However, there are individual differences in the writing pattern that the user inputs by handwriting, and even if the user intends to write a specific character, there is a large difference from the standard writing pattern registered in the handwriting character recognition dictionary. , It may not be converted to the character code intended by the user. The cause may be that the user remembers the stroke order by mistake or remembers it with continuous characters. As described above, since the characteristics of handwritten characters differ greatly among individuals, the character recognition rate is limited when only a common handwritten character recognition dictionary is used.

In order to solve this, JP-A-56-90
335, JP-A-60-134328, JP-A-63-106032, JP-A-2-292617.
As described in the publication, a favorite writing pattern (hereinafter referred to as habit character data) is stored in the storage device of the main body as personal information separately from the standard writing pattern for each user. A method of increasing the character recognition rate by inputting an ID code with an electronic pen and switching the habit character data to be used according to the ID code when performing handwriting input is known.

Further, by holding the personal information in an external storage medium such as an IC card or a floppy disk, and before using the handwriting input device, the user sets the external storage medium containing his / her personal information in the main body. , A method of increasing the character recognition rate is known.

Further, as described in Japanese Patent Application Laid-Open No. 63-223815, characters entered by the user in the main body are
Although information such as figures is held in an external storage medium containing personal information or other external storage medium, a method of temporarily storing input writing data in a storage device inside the electronic pen is also known. Has been.

[0007]

In the above prior art, in order to perform handwriting input with a high character recognition rate, it is necessary to input an ID code or set an external storage medium containing personal information in the main body. However, there is a problem that the number of operation steps increases.

Further, when an external storage medium is used,
The external storage medium must be removed from the main body after use. For example, when using the main body installed in a plurality of places, the user (1) sets the external storage medium,
(2) A procedure of holding an electronic pen for handwriting input and (3) taking out an external storage medium are required. Such a device has a drawback that if the user forgets to take out the external storage medium, it becomes difficult to use another main body. In particular, when performing handwriting input on an ATM terminal or the like used by unspecified general users, many users are unfamiliar with the machine, which is a problem.

Further, the above-mentioned conventional technique has a problem that a plurality of users cannot simultaneously perform handwriting input because a plurality of personal information cannot be used at the same time.

In view of the above problems, an object of the present invention is to provide an information processing system which does not require a special procedure, has a high character recognition rate, and allows a plurality of users to perform handwriting input at the same time. It is in.

[0011]

To achieve the above object, according to the present invention, a coordinate pointing device and a coordinate detecting device respectively output information stored in themselves to the other side,
The information output from the other party can be stored.

The coordinate pointing device may store the habit character data, which is the processing result output from the coordinate detecting device, as personal information, and the coordinate detecting device may store a common handwritten character recognition dictionary. For example, the coordinate pointing device
Since the habit character data stored in itself is output, the coordinate detection device can perform the character recognition process using the habit character data and the handwritten character recognition dictionary stored in itself.

Further, if the coordinate pointing device stores the document data as the processing result output from the coordinate detecting device as personal information, the coordinate pointing device outputs the document data stored in itself. Therefore, the coordinate detection device can perform the editing process of the document data.

Therefore, even if the user uses an arbitrary coordinate detecting device, the same operating environment becomes possible.

Further, if each coordinate pointing device stores the device identifier given to the coordinate pointing device, the coordinate pointing device outputs the device identifier and the habit character data stored therein. Therefore, the coordinate detection device can identify the coordinate pointing device. That is, the coordinate detection device can identify the habit character data output from the coordinate instruction device.

Therefore, a high character recognition rate can be maintained even if a plurality of users use one coordinate detection device almost at the same time.

The coordinate detection device stores the device identifier of the coordinate pointing device and the personal information as a set, and the personal information includes a processing result identifier and update history information given to the personal information. With this configuration, the coordinate detection device can store a plurality of personal information in one coordinate detection device by referring to the processing result identifier, and at the same time, the coordinate instruction device and the coordinate detection device. By referring to the update history information, respectively, it becomes possible to store the personal information output from the other party only when necessary.

Hereinafter, a specific configuration example of the present invention will be described.
This will be described with reference to FIG.

In FIG. 1, the coordinate pointing device corresponds to the electronic pen 101, and the coordinate detecting device corresponds to the main body 102.

The electronic pen 101 includes a CPU 103 for controlling the electronic pen 101, a power source 104 for the electronic pen,
Pen tip switch 10 for determining whether the electronic pen 101 is in a pen-down state (a state in which the electronic pen 101 is pressed against the tablet 111) or a pen-up state (a state in which the electronic pen 101 is separated from the tablet 111).
5 for exchanging information between the device 5 and the main body 102.
/ O section 106, ROM 107 that stores a pen identifier 116 assigned to the electronic pen 101, and personal information 1 including habit character data of a user who owns the electronic pen 101.
A RAM 108 storing 18 is provided.

The main body 102 exchanges information between the CPU 112 for controlling the main body 102, the power supply 110 of the main body 102, the display-integrated tablet 111, the display unit 115, and the electronic pen 101. I / O section 10
9, a ROM 114, and a pen identifier / personal information table 119 in which a pen identifier and personal information are stored as a set.
And a RAM 113 that stores

[0022]

The operation of the present invention will be described with reference to the configuration example shown in FIG.

In the electronic pen 101, when it is determined that the pen tip switch 105 is in the pen-down state,
The CPU 103 outputs the pen identifier 116 through the I / O unit 106.

In the main body 102, the tablet 111
Detects that the coordinates have been designated, the CPU 112
Receives the pen identifier 116 output from the electronic pen 101 through the I / O unit 109, searches the pen identifier / personal information table 119, and receives the pen identifier 1
The personal information (custom character data) corresponding to 16 is acquired. R
The character recognition program stored in the OM 114 performs character recognition processing using the acquired habit character data.

As a result, a plurality of users can use the same main unit 1
Even when 02 is used, if each user inputs with the electronic pen 101 that he or she owns, the character recognition processing can be automatically performed by switching the habit character data, so that the character recognition rate is improved.

When the CPU 112 cannot acquire the habit character data corresponding to the pen identifier 116, the habit character data is copied from the electronic pen 101 to the main body 102.

As a result, even when a plurality of unspecified users use the arbitrary main body 102, if each user inputs with the electronic pen 101 that he or she owns, the habit character data stored in the electronic pen 101 is used. And automatically perform handwritten character recognition processing.

When the creation of the document data is completed or the peculiar character data is updated, the document data or the peculiar character data is saved from the main body 102 to the electronic pen 101.

As a result, the portability of the personal information stored in the electronic pen 101 is expanded and the operability is improved,
By eliminating the external storage medium from the main body 102, the main body 102 can be downsized.

[0030]

However, various sizes and shapes are conceivable. Further, the main body 102 is not limited to the shape shown in FIG. 2 as long as it can detect the input coordinates by the electronic pen 101.

Further, the pen tip switch 203 synchronizes communication between the electronic pen 101 and the main body 102,
The electronic pen 101 is used to turn on / off the power, but the pen tip switch 203 may be omitted if asynchronous communication is performed and power control by timeout is used.

Further, if the power source is a combination of a solar cell or a power generation mechanism and a storage battery, or is supplied from the outside, the power switch 205 is also unnecessary.

The handwriting input device of this embodiment enables handwritten characters to be recognized with a high character recognition rate according to each habit character, even if each user has various habit characters. Is. Further, even if a plurality of users hand-write on the same main body 102 almost at the same time, it is possible to prevent erroneous recognition. In addition, the user can use the plurality of main bodies 102 by a simple procedure.

That is, in this embodiment, the habit character data of the user, the document data, and the application program used by the user are stored in the electronic pen 101 as personal information. Then, the personal information can be copied from the electronic pen 101 to the main body 102, and conversely, the personal information can be saved from the main body 102 to the electronic pen 101.

FIG. 1 is a basic block diagram of this embodiment.

First, the structure of the electronic pen 101 will be described.

In FIG. 1, 103 is a CPU for controlling the electronic pen 101, and 104 is a power source (battery) for the electronic pen 101. Reference numeral 105 denotes a pen tip switch attached to the pen tip, which detects whether or not the electronic pen 101 is in the pen-down state. Reference numeral 106 denotes an I / O unit using infrared rays, which inputs and outputs control codes and personal information with the main body 102.

In the present embodiment, the electronic pen 101 and the main body 102 are wireless, but one or more electronic pens 101 may be connected to the one or more main body 102 via a cable.

Reference numeral 107 is a ROM, and the electronic pen 1
A pen identifier 116 and an electronic pen control program 117 which are different for each 01 are stored.

In this embodiment, the pen identifier 116
Is a 2-byte code, so that all electronic pens 101 have different pen identifiers 116, from “00000” to
Although the code of “65535” is assigned, it is possible to identify more electronic pens 101 by expanding the identification code length.

Reference numeral 108 denotes a RAM, which stores the user's habit character data used for character recognition, the document data created by the user, the application program used by the user, and the personal information 1
It is stored as 18. The personal information 118 includes, in addition to the habit character data, the document data, the application program, an information classification code for distinguishing these, and the last update date and time when these were last updated.

In the present embodiment, the pen identifier 116 is data unique to the electronic pen 101 and is stored in the ROM 107 in order to avoid accidental rewriting, but it may be stored in the RAM 108. Good. In addition, in order to secure a large storage capacity, the RAM1
Instead of 08, another storage device such as a small hard disk may be used. In addition, the electronic components described above are provided in order to reduce the size of the electronic pen 101.
The cross section is circular, oval, polygonal,
It is better to use a fan shape.

Next, the structure of the main body 102 will be described.

In FIG. 1, 112 is a CPU for controlling the main body 102, 110 is a power source (battery or A / C power source) for the main body 102, 111 is a tablet for input instructions, and 115 is a liquid crystal type display section. is there. The tablet 111 and the display unit 115 are integrated with each other, and display is performed at a position corresponding to the input coordinates.

Reference numeral 109 denotes an I / O unit using infrared rays, which inputs and outputs control codes and personal information with the electronic pen 101. Reference numeral 113 denotes a RAM, which stores data generated during execution of processing, and also stores a table (hereinafter referred to as a pen identifier / personal information table) 119 in which a pen identifier and personal information are paired. The main body 1
No. 02 RAM 113 stores information common to all the electronic pens 101.
If only the information unique to the electronic pen 101 is stored in the RAM 8, the RAM 108 can be effectively used.

A ROM 114 stores a character recognition program and a main body control program 120.

FIG. 3 is a view showing the data structure of the pen identifier / personal information table 119 stored in the RAM 113 of the main body 102.

As shown in FIG. 3, in the pen identifier / personal information table 119, the pen identifier 301, the information classification code 302, the personal information 303, and the last update date / time 304 of the last update of the personal information 303 are grouped into one. One record. A record is provided for each unit information (file), and even if the information has the same pen identifier 301,
If the information classification code 302 is different, it is stored as another record.

The information classification code 302 is the personal information 303.
It is a classification code for distinguishing between, specifically, "habit data", "document data", and "application program". The last update date / time 304 is the new personal information 303 by deleting the old personal information 303 from the pen identifier / personal information table 119 when the personal information 303 exceeds the capacity of the pen identifier / personal information table 119. It is provided so that the user can remember.

The pen identifier / personal information table 119 stores a pen identifier 116 and personal information 118 output from the electronic pen 101 by a main body control program 120 described later.

Next, the electronic pen control program 117 will be described.

FIG. 4 is a flow chart of the electronic pen control program 117 stored in the ROM 107 of the electronic pen 101.

The electronic pen control program 117 is started by turning on the power switch 201 of the electronic pen 101. When activated, the electronic pen control program 117 first determines whether or not the pen tip switch 105 is in the pen-down state (step 401), and waits if it is not in the pen-down state. In this standby state, if the operating speed of the electronic pen 101 is reduced and the power saving mode is set,
It is possible to reduce power consumption.

When it is determined that the pen is down, I /
The pen identifier stored in the ROM 107, the information classification code of the personal information stored in the RAM 108, and the last update date and time are output through the O unit 106 (step 402).

Subsequently, it is determined whether or not the electronic pen 101 is in the pen-down state (step 403). When it is determined that the electronic pen 101 is in the pen-down state, whether or not a signal is input from the main body 102 through the I / O unit 106. Is determined (step 404).

When it is determined that the signal is input, it is first determined whether this signal is a personal information request signal (step 405). The personal information request signal is the main body 102
Is the pen identifier / personal information table 11 of the RAM 113.
9 is a signal to be transmitted when there is no information on the electronic pen 101 in 9. Therefore, when it is determined that the input signal is the personal information request signal, the RAM 1 is passed through the I / O unit 106.
Of the personal information stored in 08, the information corresponding to the information classification code included in the personal information request signal is output.

If it is determined that the input signal is not the personal information request signal, then it is determined whether or not it is the personal information storage signal (step 406). What is a personal information storage signal?
It is a signal transmitted when the main body 102 stores the information of the pen identifier / personal information table 119 in the electronic pen 101. Therefore, when it is determined that the input signal is the personal information storage signal, it is determined whether the pen identifier included in the personal information storage signal matches the pen identifier stored in the ROM 107 (step 408). . If it is determined that the two do not match, the information in the pen identifier / personal information table 119 is not stored. This allows the pen identifier /
It is possible to prevent the information in the personal information table 119 (for example, document data or the like) from being arbitrarily stored in the electronic pen 101 of another user in the vicinity. When it is determined that the two match, the information classification code, personal information, and last update date and time that are subsequently input through the I / O unit 106 are stored in the RAM.
It is stored in 108 (step 409). The last update date and time is stored in the electronic pen 101 for the purpose of comparing old and new personal information stored in the electronic pen 101 and personal information stored in the main body 102. If the last update date and time of the electronic pen 101 is newer than the last update date and time of the main body 102, it means that the personal information of the electronic pen 101 has been updated by another main body 102.
The personal information is copied from 01 to the main body 102 and processed.

Above, steps 403 to 409
The processes up to are repeated until the pen-down state ends. When the pen-down state ends, the process returns to step 401 and waits until the pen-down state is restored.

Next, the main body control program 120 will be described.

FIG. 5 is a flow chart of the main body control program 120 stored in the ROM 114 of the main body 102.

The main body control program 120 is stored in the main body 202.
It is started by turning on the power switch 205. When activated, the main body control program 120 first determines whether or not there is an input to the tablet 111 by the electronic pen 101 (step 501). If it is determined that there is no input, the character recognition processing of the stroke that has already been input is performed (step 502) to shorten the character recognition processing time or reduce the operation speed of the main body to enter the power saving mode. Thus, it is possible to reduce power consumption.

When it is determined that there is an input to the tablet 111 by the electronic pen 101, the I / O unit 109
The pen identifier output from the electronic pen 101, the information classification code of personal information, and the last update date and time are received and temporarily stored in the RAM 113 (step 50).
3).

Subsequently, it is determined whether the data to be input by the electronic pen 101 is character stroke data (step 504). Here, the criterion is that the coordinates of the designated point are inside the previously displayed character input area. If it is determined that the data is character stroke data, the pen identifier / personal information table 119 stored in the main body RAM 113 is searched for the pen identifier temporarily stored in the RAM 113 (step 505). Then, it is determined whether or not the pen identifier / personal information table 119 includes the input pen identifier, and further whether or not there is a record having the same information classification code (step 506). If it is determined that there is not, the electronic pen 101 A personal information copying process for copying the personal information stored in the pen identifier / personal information table 119 is performed (step 507). The personal information copying process of step 507 will be described later.

As described above, the personal information of the electronic pen 101 is automatically copied to the main body 102, and the habit character data, the document data, and the application program of the user performing the input operation are used. The same operating environment can be obtained regardless of which main body 102 is used.

Even if the pen identifier / personal information table 119 has personal information with the same pen identifier and the same information classification code in the determination at step 506, the last updated date and time that was input is the pen identifier / personal information table. 119
If it is newer than the last updated date and time (step 50)
8) Since it means that the personal information of the electronic pen 101 has been updated by another main body 102, the personal information copying process is performed (step 507).

On the contrary, if the last updated date and time that was input is older than the last updated date and time of the pen identifier / personal information table 119, the personal information of the electronic pen 101 has been initialized, so the personal information copying process is performed. Does not. Also, the last updated date and time that was input is the pen identifier / personal information table 1
If it is equal to the final update date and time of 19, the personal information of the main body 102 is used, and therefore the personal information copying process is not performed.

In this way, the unnecessary personal information copying process can be eliminated by copying the personal information from the electronic pen 101 to the main body 102 only when necessary.

Subsequently, each stroke data or character is stored in the RAM 113 in association with the pen identifier of the input electronic pen 101 (step 509).

As a result, when the stroke data is recognized in the character recognition process, the habit character data for character recognition can be switched and recognized for each character. Tablet 11
Even if characters are input to 1, the same character recognition rate as when inputting by one person can be obtained, which is effective for applications such as a handwritten electronic blackboard.

Subsequently, the stroke data that is input at any time is stored and displayed on the display unit 115 (step 5).
10). The stroke data is stored and displayed until the electronic pen 101 is separated from the tablet 111 (step 511).

On the other hand, if it is determined in step 504 that the input data is not stroke data, it is determined whether or not it is a personal information storage instruction (step 51).
2). Here, the criterion is that the coordinates of the designated point are inside the personal information storage designated area (which can be realized as an icon, for example) displayed in advance. If it is determined that the instruction is a personal information storage instruction, a personal information storage signal including a pen identifier (identifier of the electronic pen that has issued the personal information storage instruction) previously temporarily stored in the RAM 113 is sent through the I / O unit 109. , To the electronic pen 101 (step 513). Then, among the personal information of the main body 102, the last update date and time of all updated files are updated, and I
The information classification code, the last update date and time, and the personal information of all the updated files are output through the / O unit 109 (step 514).

Thus, for example, when the document data is updated but the habit character data is not updated, only the updated document data is copied to the electronic pen 101 and the habit is not updated. Character data is not sent,
It is possible to eliminate unnecessary communication costs.

Here, the personal information is copied from the main body 102 to the electronic pen 101 only when there is an instruction to save the personal information. However, each time the pen-up state is determined, the personal information is copied up to the present time. Main body 1 with updated personal information
By copying from 02 to the electronic pen 101, the user can interrupt the input operation at any time, and can always store the latest personal information in the electronic pen 101.

Next, the personal information copying process in step 507 will be described with reference to FIG.

First, the personal information request signal including the information classification code is output through the I / O unit 109 (step 6).
01). Further, when a specific file having an old last update date is copied to the main body 102 among a plurality of files in the RAM 108 of the electronic pen 101, the information classification code is also added and output. After that, the personal information output from the electronic pen 101 is received through the I / O unit 109 and the RAM
It is temporarily stored in 113 (step 602).

Next, the pen identifier / personal information table 1
It is determined whether or not there is a record having the same information classification code with the same pen identifier in 19 (step 60).
3). If it is determined that there is a record with the same pen identifier and the same information classification code, it means that the data of the pen identifier / personal information table 119 is old data, so that record is first stored in the RAM 113. The pen identifier and personal information stored temporarily are overwritten (step 604).

If it is determined that there is no record having the same information classification code with the same pen identifier, it is determined whether or not there is a blank record in the pen identifier / personal information table 119 (step 605), and a blank record is obtained. If there is not, the last update date and time of each record of the pen identifier / personal information table 119 is compared, the oldest record is deleted, and an empty record is secured (step 606). Then, the pen identifier and the personal information temporarily stored in the RAM 113 are registered in the deleted record (step 607).

In this embodiment, the main body control program 120 copies the personal information of the electronic pen 101 to the main body 102 when the personal information of the electronic pen 101 is used. By directly accessing the RAM 108 of the electronic pen 101 through communication, the RAM 113 of the main body 102 can be reduced or effectively utilized.

As described above, in the present embodiment, the personal information is stored in the electronic pen 101, and the personal information stored in the electronic pen 101 is copied to the main body 102 or stored in the main body 102. Since the stored personal information is stored in the electronic pen 101, the handwritten character can be recognized with a high character recognition rate according to the habit character data for each user. Further, even if a plurality of users input handwriting on the same main body almost at the same time, it is possible to prevent erroneous recognition. Further, regardless of which main body 102 the user uses, it is possible to provide the same operating environment to the user.

In this embodiment, the habit character data,
Although the document data and the application program used by the user are stored in the electronic pen 101, they may be merely habit character data. In this case, the user is
When using, the document data and the application program need to be stored in the external storage medium and set in the main body 102 to be used, but the information classification code becomes unnecessary.

Further, in this embodiment, the personal information includes the habit character data, the document data, and the application program, but in addition to this, the deposit data, the address book data, the proof of the license / permission. Writing data, schedule data, etc. may be stored as personal information. As a result, not only can the main body 102 be used to create and edit document data, but the main body 102 can be used according to various purposes.

Next, a method of creating habit character data will be briefly described.

The method of creating habit character data is similar to that of the conventional technique, except that the storage destination is the electronic pen 101.

That is, first, when the user gives an instruction to execute the habit character registration function, a character frame 1 for inputting a desired character and a character frame 2 for inputting a writing pattern of the user.
And are displayed. The user inputs a desired character into the character frame 1 by using the kana-kanji conversion processing, inputs into the character frame 2 a favorite writing pattern to be associated with the character input into the character frame 1, and then issues a registration instruction. As a result, the writing pattern input to the character frame 2 and the character input to the character frame 1 are associated with each other in addition to the standard pattern, and habit character data is created. With the conventional technology, the created habit character data is
It is stored in the main body 102 or an external storage medium set in the main body 102, but in the present embodiment, it is output from the main body 102 to the electronic pen 101 and stored in the electronic pen 101.

The form of the information processing system utilizing the features of the handwriting input device of this embodiment will be described below with reference to FIG.
