Description

  The present invention relates to an electronic pen input data processing system, and more particularly to an electronic pen input data processing system that facilitates creation of an input form form and data input and update.

  Conventionally, there is an electronic storage system that keeps all business documents as official records. A typical example of this type of system is an electronic medical record system in medical work. Some electronic medical record systems can use handwritten data registered in a database using a tablet or an electronic pen. For example, there is a system that stores a handwritten part as an image using a tablet. There is also a system that uses electronic pen paper and an electronic pen to realize digitization with almost no change in handwriting operation. Some systems allow handwritten documents and coded data to be registered and used in a database.

  In a document digitization system that uses an electronic pen, data can be input by writing characters on paper with the electronic pen. For example, with the Anoto digital pen, it is possible to read what was written by writing characters on an Anoto pattern paper on which a form of a form is printed. Anoto pattern paper is printed with a pattern composed of very small dots (lattice with a spacing of about 0.3 mm). With this pattern, the electronic pen acquires coordinates. The Anoto digital pen has a built-in micro camera at the tip of the pen, and captures information written on a special paper into the pen as digital information. Since it can be used as an ordinary ballpoint pen, you can leave what you write on plain paper. What the Anoto digital pen can memorize is the pen position information, pen trajectory (writing order), writing speed, writing pressure, writing date, pen tilt, and the like. Data input from the electronic pen is recognized and converted into a character string, and the coordinates of the form are associated with the input data and managed in the database. By defining the layout of the form and the record items, it can be operated almost the same as the paper form.

  In such a document digitization system, authenticity, legibility and storability, which are advocated as the three principles of the electronic medical record, are ensured, and it has characteristics necessary for an official document. Authenticity refers to information that has been recorded and confirmed by a legitimate person, and the responsibility and location of the creation is clear from the perspective of a third party, and false input, rewriting, erasure, and confusion due to intention or negligence are prevented. It is that. Security is maintained by message authentication. Readability means that contents stored in an electronic medium can be easily read by the naked eye as necessary. To ensure readability or readability. The storability means that the recorded information is stored in a state in which it can be read and kept authentic over a period defined by laws and regulations. The following are some examples of prior art related to document digitization systems.

  The “comprehensive medical information management system” disclosed in Patent Document 1 is a system that comprehensively handles a report from each department in cooperation with an electronic medical record. As shown in Fig. 6 (a), findings reports, etc. are sent to the server as a print image file with a file name including patient identification code and classification code from the subsystem of each medical department in the computer network. To do. The server decodes the patient identification code and sends a report to the category code folder in the patient chart folder.

  The “chart digitization processing method” disclosed in Patent Document 2 is a processing method that satisfies authenticity and legibility. As shown in FIG. 6B, a medical record form and an electronic medical record are displayed on the pen tablet. Handwritten characters and sketch images with a stylus pen and text characters and numerical values with a keyboard or the like are written as medical information. The chart form and medical information are stored in two types: an image file and a tagged text file. A file name is formed by concatenating doctor patient identification information and medical treatment time.

  The “material creation method” disclosed in Patent Document 3 is a method for easily creating individual and specific materials by using main and slave data separated and displayed on both sides of a computer screen and combining them at the center of the screen. It is. As shown in FIG. 6C, a customer ledger and a product ledger are prepared as databases. The customer data is searched from the customer ledger based on the customer search condition and displayed on the right side of the display screen. Candidate product search information is created with reference to customer data. A product to be associated with the customer is searched from the product ledger based on the product search condition and displayed on the left side of the display screen. The customer data and the product are moved to the center of the display screen, the details are synthesized and displayed, and output as a document.

  The “electronic pen” disclosed in Patent Document 4 is a pen that detects the position of each point of a written character and electronically records a stroke. As shown in FIG. 6D, the electronic pen includes writing means and an image detection unit. The image detection unit includes an image sensor and a processor for determining the position of the pen based on the image. A position detection pattern drawn on the paper is detected by an image sensor and recognized by a processor to detect the position of the pen, and the pen stroke is converted into an array of positions.

  The “medical chart management system” disclosed in Patent Document 5 is designed to facilitate data management, search, and the like even when a paper medical chart is used. As shown in FIG. 6E, the electronic pen optically reads the dot pattern from the medical chart paper, thereby acquiring position data corresponding to the written content and transmitting it wirelessly. The data is received by the medical chart management device and registered in the database. When the additional entry data is received, if the corresponding data is registered in the database, it is registered in association with the database.

  The “electronic pen for recording handwritten information” disclosed in Patent Document 6 electronically records the movement of the electronic pen on the paper. As shown in FIG. 6F, the electronic pen stores the pen stroke on the paper. There are pen strokes indicating graphic information and pen stroke processing commands. Detect the current operation of the electronic pen and process the set of pen strokes.

The “electronic medical record construction system” disclosed in Patent Document 7 digitizes a medical chart in the same manner as a handwritten medical chart. As shown in FIG. 6G, the electronic medical record data is input by handwriting. A single system is used for unified management while mixing handwritten and electronic medical records.

The pattern merging unit 10 is a means for superposing dot patterns, form forms, and data into print data. The form management unit 11 is a means for managing the update state of the form.

  The electronic pen paper 100 is paper (Anoto paper) on which a dot pattern for the electronic pen to acquire coordinates is printed. Clients 200 and 210 are personal computers of user terminals. The keyboards 201 and 211 are personal computer input devices. The mice 202 and 212 are PC pointing devices. The printer 203 is a device that prints electronic pen paper and the like.

The PGC file 310 is a file composed of output data of the electronic pen. The ICR unit 312 is a means for performing character recognition (Intelligent Character Recognition). The network 400 is a communication network such as the Internet or a LAN. Operators 501 and 502 are users who operate the client terminal.

  The function and operation of the pen input data processing system configured as described above in the embodiment of the present invention will be described. First, an overview of the functions of the pen input data processing system will be described. A mount is displayed on the screen of the client terminal, and a sample of the input field is also displayed. When the input field is selected, the selected input field is displayed on the mount. Modify the attributes in the input field as necessary. The position of the mount on which the input field is overlaid is associated with the input field, and data in which the position of the mount is related to the input field is stored as an input form. In this way, the user creates and registers a form for electronic pen input.

  An electronic pen paper is printed by superimposing a form on a dot pattern for the electronic pen to acquire coordinates. In the case of update input such as additional writing or correction, an output form in which the already input data is written is printed over the dot pattern. When characters are written on the electronic pen paper with the electronic pen, electronic pen data including pen identification information, writing position, writing pressure, and time is sent from the electronic pen to the client terminal. The stroke analysis unit extracts trajectory information from the electronic pen data and performs stroke analysis. Data processing such as character recognition is executed according to the stroke analysis result. A character recognition unit recognizes the trajectory information and generates a character string. The character string and electronic pen paper input field are associated and registered as form data in the database.

  Since data can also be input to the form from other input means including a keyboard or a mouse, exclusive control is performed in order to prevent conflict of simultaneous input data for the same form. Referring to the document management table and the form management table, the occurrence of a conflict of input data for the same form is checked. When a conflict occurs, the input data is put on the registration hold list without being overwritten by the input data from the electronic pen. Display the registration hold list and select whether to update.

  Next, a specific operation will be described with reference to FIG. As shown in FIGS. 1A and 1B, when characters or the like are written on the electronic pen paper 100 with the electronic pen 1, the ID of the electronic pen 1, the locus (writing order), position information (coordinates), The speed, pen pressure, and date of writing are acquired. The locus coordinates of the electronic pen 1 are read from the electronic pen paper 100, and the data is sent to the client 200 via USB or wireless as encrypted binary data. The electronic pen 1 can be input via USB or wirelessly, and data is input to the input control unit 2. The input control unit 2 creates a PGC file and sends it to the server 300. The processing so far is the processing in the client 200.

  The server 300 cuts out a portion corresponding to the input field to be converted from the PGC file created by the input control unit 2, recognizes the trajectory information of the electronic pen 1 by the OCR unit 3, and converts it into a character string. The stroke analysis unit 4 cuts out trajectory information from the PGC file and performs stroke analysis. The data processing type is determined based on the result of the stroke analysis, and the corresponding macro command is executed. As a result, unprocessed input field data is found from the electronic pen data, and a process corresponding to the attribute is performed.

  The document management unit 5 manages the document with the same layout as the paper form and stores it in the database 301. The PGC file of the output data of the electronic pen 1 is collated with the managed form information, managed and stored with the ID for each form. Since the document is a paper-based layout, the form is highly readable. For this part, you can use the existing system called Yahgee Small Cabinet. This is a tool that allows a user to automatically construct a background image, a field item name, its layout, and a database definition called a mount without understanding the structure.

  The registration unit 6 transfers and stores data to be registered in the database 301. An existing system called Yahgee Document View can be used. This is a tool that performs input / output to a database with a form image by processing data in three layers of a background image, layout, and input items called a mount. A macro command for the stroke analysis result is registered in the macro registration unit 7. For example, a procedure for automatically executing individual operations of the Yahgee series is registered. The macro execution unit 8 executes a macro command corresponding to the result obtained by the stroke analysis.

  The pattern merge unit 10 creates print data for printing with dot patterns superimposed on the input data. For example, the stroke information (pen trajectory) input from the electronic pen 1 is reflected on the Anoto paper (Postscript format file) created by Anoto FDT (Forms Design Tool, part of SDK), and the Yahgee Document View The input data is reflected on the Anoto sheet, and a new Anoto sheet is created. The printing unit 9 prints a form or the like on which dot patterns for the electronic pen 1 to acquire coordinates are superimposed. The form management unit 11 manages the coordinates of the form in association with the input data. For example, the association between Anoto paper (Postscript) created by Anoto FDT, its control information (PAD), and document information of Yahgee Document View is managed.

  Next, a method for creating a form form will be described. A mount frame for electronic pen input is displayed on the client screen. It also displays a sample in the input field. Select one sample in the input field and drag it onto the mount. Select or modify the attributes in the entry field as necessary. For a field for recognizing and inputting handwritten characters, character recognition is selected as an attribute. By simply selecting an attribute in the input field, the data input in that field is processed according to the attribute and stored in the database. The position of the mount on which the input field is superimposed is associated with the input field. Repeat as necessary. When completed, data in which the position of the mount is related to the input field is registered as an input form. You can use the sample form as it is. It can also be created by modifying the sample form. A new input field can also be created.

  Next, with reference to FIG. 2, two input methods using an electronic pen and a keyboard / mouse will be described. As shown in FIG. 2A, the operator 501 fills in the electronic pen paper 100 with the electronic pen 1 and stores it in the database 301 of the server 300 via the network 400. Thereafter, the operator 502 may open the database 301 on the client 210 and perform editing work. In the case of a server / client system, an exclusive lock is applied to the database 301 here. For example, the operator 501 cannot edit the data stored in the database 301 in the client 200. However, since the electronic pen paper 100 and the electronic pen 1 are not directly connected to the server 300, normal exclusive control cannot be applied.

  In addition, since the system clock connected to the server 300 and the clock built in the electronic pen 1 do not always coincide with each other, a problem may occur in the order of input. The time of the clock built in the electronic pen 1 is synchronized with the system time of the client 200 when connected to the USB interface for data transmission or charging. When data is transmitted wirelessly, the time data of the built-in clock of the electronic pen 1 is used as it is and recorded. For this reason, apart from the time of the input data, the time at the time of transmission to the client 200 is stored together with the authentication data from the public time certification authority, and the time difference at that time is taken into account. Establish ordering.

  As shown in FIG. 2B, the editing screen 220 and the reference screen 221 can be opened at the same time, and reference items can be copied and edited using a keyboard or a mouse. As described above, since the electronic pen input and the keyboard input can be performed on the same paper-based layout, the electronic pen input and the input by the keyboard and the mouse can be operated while freely used. The entered content can be printed on paper at any time, and additional entries and corrections can be made, enabling turnaround operations that repeat input and printing. Since data items in units of forms such as input with an electronic pen, text, photos, graphs, videos, voices, and other digital data can be associated as common contents, data with complicated configurations can be easily managed. Since various search functions including text mining are provided, necessary data can be easily found.

  Next, an exclusive control method in the simultaneous update of the same form will be described with reference to FIGS. As shown in FIG. 3, when a character or the like is written on the electronic pen paper 100 with the electronic pen 1, data from the electronic pen 1 is input to the Anoto SDK 217 via the USB interface 213 and the USB driver 216 of the client 200. Alternatively, the data file 215 is input via the wireless driver 218. The input handwritten information is integrated by the input control unit 2 to be a PGC file 310 having a common data format. The common PGC file 310 is sent from the input control unit 2 to the server 300 through the network 400.

  The stroke analysis unit 4 of the server 300 acquires and analyzes the trajectory information from the common PGC file 310 and determines the data processing method. The ICR unit 312 converts stroke information into a character string, and the OCR unit 3 converts image information into a character string. The exclusive control unit 305 manages the update history of the form with the document management table 303 and manages the update state of the form with the form management table 302. The simultaneous update for the same form is monitored, and if a conflict occurs, the exclusive control is performed so that the update is not performed with the electronic pen data but is put on the registration suspension list. Contention occurs in the following cases.

  As shown in FIG. 4A, when the operator 501 inputs handwriting on the electronic pen paper 100 with the electronic pen 1, the information is sent to the server 300 via the client 200 and the network 400. When another operator 502 inputs data into the same form using the keyboard 211 or the mouse 212 of the client 210, the information is also sent to the server 300 via the client 210 and the network 400. The exclusive control unit 305 of the server 300 accesses the form management table 302 and the document management table 303, refers to the address used for input, the item frame of the form, and the update date / time of data registered in the past, thereby Check. When another operator 502 has updated the data of the form with the keyboard 211 at the time when the input from the electronic pen 1 is generated, the input data from the electronic pen 1 is accumulated as reserved data. A specific flow of this exclusion process is shown in FIG.

  In the flowchart shown in FIG. 5, when data is input to a form from the keyboard, a form address is acquired based on the document management number in the document management table 303 shown in FIG. In step 2, a management record corresponding to the form address is acquired. In step 3, 1 is added to update number # 1 in the form management table 302 shown in FIG. When data is input to the form from the electronic pen 1, a form address is acquired from the PGC file 310 in step 4. In step 5, a management record corresponding to the form address is acquired. In step 6, it is checked whether update number # 1 is 0 or not. Since 0 is a new input, new input processing is performed in step 7. If it is not 0, it is checked in step 8 whether the update number # 1 is larger than the update number # 2. If it is larger, a conflict has occurred. In step 9, a hold process is performed. In step 10, 1 is added to update number # 1, and update number # 2 is made the same as update number # 1. In step 11, the current document management number is numbered, the validity flag of the previous document is set to False, and the validity flag of the current document is set to true.

  When the pending data occurs, the operator 501 is notified of an error. The error in this case is displayed on the screen of the connected terminal in the case of USB connection. In the case of wireless connection, the operator 501 can be notified by vibration of the electronic pen. When an error occurs, it is possible to check the hold state on the display device of the client 200. As shown in FIG. 4B, when the document screen is opened, the pending data is displayed on the right side of the screen. The merge operation can be easily performed by drag & drop or copy & paste while checking the update contents.

  By operating in such a way that no input occurs at the same time, it is possible to avoid the contention problem, but it becomes difficult to use. In an environment where communication with the electronic pen can be performed in real time, it is possible to avoid contention by checking the exclusive lock at the start of filling in the electronic pen paper 100, but the usage conditions are limited. Become. When updating data with the keyboard / mouse, you can input while checking the race condition. However, when entering with the electronic pen, you need to check the screen by interrupting the entry process or not. Yes, it becomes unusable. In order to improve usability, input from the electronic pen should be completed even if there is a conflict. After completing the input, check the screen and perform the actual update process. By doing so, the data update operation can be performed by taking advantage of the advantage of the electronic pen, so the convenience is not impaired.

  If both clients update the form with the electronic pen, the form is updated with one input and the other input is put on hold. In addition, when the form is updated with the keyboard / mouse in both clients, one of the inputs may be put on hold or the update may be prohibited. Since it is unlikely that three clients will update the same form at the same time, even if the update input from the third client is prohibited, there will be no difficulty in use.

  As described above, in the embodiment of the present invention, the pen input data processing system recognizes the character and the position of the electronic pen input form that the user creates on the terminal and fills in the form with the electronic pen. Since the data entered in the form is managed by the database and the simultaneous update of the same form data is exclusively controlled, the system can be constructed and expanded at the end user level.

  The pen input data processing system of the present invention is most suitable as an electronic storage system for documents in general business that leaves documents as official records, like an electronic medical record system in medical business. It can also be applied to systems in fields such as finance, manufacturing and distribution.
