(Step S1: Projection process in FIG. 3)
For the procedure selected by the user, the projection unit 111 projects and displays on the input table 40 the input format 84 in which the input content 85 and the input field 86 are designated by the projector 20.

The projection processing according to the first embodiment will be described with reference to FIGS.
(Step S11 in FIG. 4: Procedure selection process)
As shown in FIG. 5, the projection unit 111 causes the projector 20 to display a procedure selection screen 81 on the input table 40. The selection screen 81 shows selectable procedure buttons. In FIG. 5, account opening, deposit withdrawal, address change, name change, seal change, and transfer are shown as procedure buttons. The selection screen 81 is displayed on a part of the projection surface 21 that can be projected by the projector 20 on the input table 40.
Then, the button of the procedure to be performed is touched with the electronic pen 30 and selected by the user.

(Step S12 in FIG. 4: display content reading process)
The projection unit 111 reads the display content 82 for the procedure selected in step S11 from the display content storage unit 51 of the database server 50.
As shown in FIG. 6, the display content storage unit 51 stores display content 82 for each procedure. The display content 82 includes a list 83 indicating the input order of the input content 85 for the target procedure, and an input format 84 for each input content 85.
For example, if the procedure is to open an account, the list 83 indicates that the input content 85 is in the input order of name, address, date of birth, telephone number, and amount. The display content 82 includes an input format 84 for the name, address, date of birth, telephone number, and amount.

(Step S13 in FIG. 4: Display content projection processing)
The projection unit 111 projects and displays the display content 82 read in step S <b> 12 on the input table 40 by the projector 20.
As illustrated in FIG. 7, when the account opening is selected in step S <b> 11, the projecting unit 111 projects and displays the list 83 and the input format 84 for the name whose input order is the first input content 85. In the list 83, a plurality of input contents 85 are arranged in the order of input, and the input contents 85 to be input are indicated by stars.

  Further, as shown in FIG. 7, the projection unit 111 may display buttons for enlarging and reducing the display contents. When the enlarge button is touched, the projection unit 111 enlarges and displays the entire display content 82. That is, as shown in FIG. 7, since the display content 82 is displayed on a part of the projection plane 21, the entire display content 82 can be enlarged and displayed. Further, when the reduction button is touched, the projection unit 111 reduces and displays the entire display content 82.

(Step S2 in FIG. 3: data recognition processing)
The data recognition unit 112 recognizes characters handwritten in the input field 86 of the input format 84 projected and displayed by the projection unit 111 in step S1.

A data recognition process according to the first embodiment will be described with reference to FIGS.
(Step S21 in FIG. 8: recognition process)
The content corresponding to the input content 85 is handwritten with the electronic pen 30 in the input field 86 by the user. For example, as shown in FIG. 7, when the input format 84 for the name is projected and displayed, the user's name is handwritten in the input field 86.
Each time the data recognition unit 112 is handwritten in the input field 86, it recognizes the handwritten character. That is, the data recognizing unit 112 re-recognizes a character each time a stroke is handwritten in the input field 86.
At this time, first, the data recognition unit 112 identifies the locus of the position of the electronic pen 30. Any method may be used to identify the locus of the position. For example, the position of the electronic pen 30 may be specified by the data recognition unit 112 communicating with the electronic pen 30, or the infrared ray is placed on the input table 40 by the projector 20 to specify the position of the electronic pen 30. May be. In addition, when using infrared rays, it is also possible to write a character with a finger etc. instead of the electronic pen 30.
Next, the data recognizing unit 112 performs OCR (Optical Character Reader) processing based on the specified locus, recognizes the handwritten character, and converts it into a character code. The OCR process is a process of optically reading a handwritten or printed character and converting it into a character code that can be used by a computer. The data recognition unit 112 may use any OCR software. For example, the data recognition unit 112 uses OCR software that recognizes characters in consideration of the shape of the written characters, the writing order, and the like.

(Step S22 in FIG. 8: deficiency determination processing)
The data recognition unit 112 determines whether or not the character recognized in step S21 is incomplete. For example, the data recognizing unit 112 determines that there is a defect when a character other than a numerical value is input to the input field 86 for inputting a numerical value.

(Step S23 in FIG. 8: Imaging Process) The data recognition unit 112 images the trajectory identified in step S21 and transmits the imaged trajectory to the projection unit 111. In addition, the data recognition unit 112 transmits the character recognized by the OCR process in step S21 to the projection unit 111.
For example, as shown in FIG. 7, an imaged trajectory is displayed in the input field 86. In addition, the character string converted by the OCR process is displayed below the input field 86.

If it is determined in step S22 that there is a deficiency, the data recognition unit 112 notifies the user that there is a deficiency and prompts correction.
For example, if it is determined in step S22 that there is a deficiency, the data recognizing unit 112 also transmits data indicating that there is a deficiency to the projection unit 111 together with the character string converted. The projection unit 111 notifies the user that there is a deficiency by a method of projecting and displaying the recognized characters.

(Step S24 in FIG. 8: Write end determination process)
The data recognition unit 112 determines whether or not the writing to the input field 86 has been completed. Here, the data recognizing unit 112 determines that the writing to the input field 86 is completed when the button indicating that the writing to the input field 86 is completed is touched. In FIG. 7, the data recognizing unit 112 determines that the writing to the input field 86 is completed when the lower right arrow button of the input format 84 is touched.
If it is determined that the writing to the input field 86 has been completed, the data recognition unit 112 advances the process to step S25. On the other hand, if it is determined that the writing to the input field 86 has not been completed, the data recognition unit 112 returns the process to step S21 to recognize the next character.
The data recognizing unit stores the recognized character as digital data at the time when the writing into the input field is completed, and also images the identified locus and stores it as trail data.

When it is determined that the writing to the input field 86 has been completed, the data recognition unit 112 may re-determine whether there is a deficiency in the characters written to the input field 86.
In step S22, it is possible to determine the deficiency of the recognized character. On the other hand, when it is determined that the writing to the input field 86 has been completed, it is possible to determine whether or not the character string written to the input field 86 is incomplete. For example, when the input content 85 is a telephone number, it can be determined that the number of written numerical values is large or small.

(Step S25 in FIG. 8: Procedure End Determination Processing)
The data recognition unit 112 determines whether or not the writing for all the input contents 85 has been completed. Here, when the writing to the input column 86 for the last input content 85 is completed, it is determined that the writing for all the input content 85 is completed.
If the data recognition unit 112 determines that all the input contents 85 have been written, the process proceeds to step S3 in FIG. On the other hand, if the writing for all the input contents 85 has not been completed, the data recognition unit 112 returns the process to step S13 in FIG. 4 to display the input format 84 for the next input contents 85.

  For example, when the input format 84 for the name shown in FIG. 7 is projected and displayed, when the arrow button on the lower right is touched, the data recognition unit 112 performs the process in step S13 of FIG. Return to. Then, as shown in FIG. 9, the projection unit 111 projects and displays the input format 84 for the address having the second input content 85 in the input order.

(Step S3 in FIG. 3: confirmation processing)
The confirmation processing unit 113 generates confirmation data 88 for confirming the character written in step S2.

The confirmation process according to the first embodiment will be described with reference to FIGS.
(Step S31 in FIG. 10: format acquisition process)
The confirmation processing unit 113 reads the procedure document format 87 for the procedure selected in step S11 from the format storage unit 52 of the database server 50.
As shown in FIG. 11, the format storage unit 52 stores the format of the procedure document for each procedure. The procedure document format 87 is, for example, the same format as a conventional paper procedure document. Each input column 86 indicated by the input format 84 of the display content 82 corresponds to an entry column for procedure documents.

(Step S32 in FIG. 10: confirmation data generation process)
As shown in FIG. 12, the confirmation processing unit 113 places the character recognized in step S2 in the entry field of the format 87 of the procedure document acquired in step S31 corresponding to the input field 86 in which the character is handwritten. The confirmation data 88 is generated. FIG. 12 shows confirmation data 88 in the case of opening an account. Therefore, in FIG. 12, the name, address, date of birth, telephone number, and amount are shown.

  When the confirmation processing unit 113 generates the confirmation data 88, the confirmation processing unit 113 may re-determine whether there are any deficiencies in the characters written in the input fields 86. Here, it can be determined whether or not the correspondence between the character strings written in the input fields 86 is incomplete. For example, it can be determined that the address and the area code of the telephone number do not match.

(Step S33 in FIG. 10: Procedure execution determination process)
The confirmation processing unit 113 transmits the generated confirmation data 88 to the projection unit 111. The projection unit 111 projects and displays the confirmation data 88 on the input table 40.
The contents of the confirmation data 88 are confirmed by the user. If the content of the confirmation data 88 is not corrected, a button indicating that the procedure is executed by the user is touched with the electronic pen 30. Then, the confirmation processing unit 113 proceeds with the process to step S34. On the other hand, if the contents of the confirmation data 88 are corrected, the electronic pen 30 touches a button indicating that the confirmation data 88 is corrected. Then, the confirmation processing unit 113 causes the projection unit 111 to project and display a correction screen for the corresponding input content 85. Then, after completing the correction, the confirmation processing unit 113 returns the process to step S32 to regenerate the confirmation data 88.

(Step S34 in FIG. 10: User information storage process)
The confirmation processing unit 113 transmits data such as characters for each input content 85 recognized in step S2 to a terminal of a clerk at a procedure destination such as a financial institution. When the clerk confirms that there is no deficiency in the data, the confirmation processing unit 113 writes the data into the user information storage unit 53 of the database server 50. As shown in FIG. 13, the user information storage unit 53 stores information about the user for each user.

(Step S35 in FIG. 10: reference information generation process)
The confirmation processing unit 113 generates reference information 89 for referring to information about the procedure document from the user terminal. Information about the procedure documents includes information about registered users and the progress of the procedure. The reference information 89 indicates a URL (Uniform Resource Locator) that can refer to information on the procedure document. For example, the reference information 89 is a two-dimensional code in which a URL is embedded. The user terminal is a terminal such as a smartphone or a mobile phone. The user can refer to the information on the procedure document by specifying the URL indicated by the reference information 89 and accessing the website using the user terminal.
The confirmation processing unit 113 transmits the generated reference information 89 to the projection unit 111. The projection unit 111 projects the reference information 89 on the input table 40. For example, the URL indicated by the reference information 89 can be taken into the user terminal by reading a two-dimensional code using a camera attached to the user terminal.

  The procedure is advanced by a clerk at the procedure destination such as a financial institution using the data written in the user information storage unit 53 in step S34 of FIG. The progress of the procedure is registered in the database server 50 by the clerk, and the information on the website indicated by the URL indicated by the reference information 89 is updated.

*** Effects of Embodiment 1 ***

In particular, the projection surface 21 can be easily enlarged. For this reason, it is possible to easily display the input format 84 in a large size.
Further, an explanation and an input example corresponding to the input content 85 can be displayed on the input format 84 or can be displayed outside the input format 84.

  Further, the data input device 10 according to the first embodiment projects and displays a description corresponding to the input content 85 and an input example. Therefore, the user can write the input content 85 smoothly. As a result, it is possible to reduce the congestion of the procedure window. In addition, since the number of inquiries to the clerk is reduced, it is possible to reduce the inability of the clerk to work.

  In addition, the data input device 10 according to the first embodiment stores the characters recognized by the OCR process as digital data, images the specified locus, and saves it as trail data. Therefore, even if there is an inquiry about the procedure contents from the user at a later date, it is possible to confirm the procedure contents.

Further, the data input device 10 according to the first embodiment does not require a paper procedure document. Therefore, when there is a change in the input content 85 necessary for the procedure, it can be dealt with by simply changing the data stored in the database server 50.
In addition, when the explanation is projected on the procedural document as in Patent Document 1, a complicated procedure such as changing the paper procedural document and adjusting the position of the explanation projected on the procedural document is required.

A document such as a driver's license for a car is installed in the imaging area of the imaging device 70 by the user.
The data recognizing unit 112 captures the document set in the imaging region by the imaging device 70 and acquires image data of the document. The data recognition unit 112 recognizes characters corresponding to each input content 85 from the acquired image data. The data recognition unit 112 treats the recognized character as the character input in the corresponding input field 86 in the input format 84.
Here, a document in which the input contents are determined is installed like a car driver's license. In addition, other documents such as a passport and an insurance card may be used instead of the driver's license of the car. In addition, each column of the document is associated with each input content 85 of the display content 82 in advance.
The data recognition unit 112 transmits the recognized character to the projection unit 111. Then, the character recognized by the projection unit 111 is displayed below the input field 86. Alternatively, it may be displayed in the input field 86 or may be displayed only in the input field 86.

*** Effects of Embodiment 2 ***
As described above, the data input device 10 according to the second embodiment recognizes characters written in a document such as a driver's license of a car and treats them as characters input in the input field 86. As a result, it is possible to reduce the trouble for the user to write the input content 85.

Embodiment 3 FIG.
The third embodiment is different from the first embodiment in that statistics relating to writing are taken. In the third embodiment, this different point will be described, and the description of the same point will be omitted.
Note that Embodiment 3 can be combined with Embodiment 2.

*** Explanation of configuration ***
With reference to FIG. 17, the structure of the data input device 10 which concerns on Embodiment 3 is demonstrated.
The data input device 10 is different from the data input device 10 shown in FIG. 3 in that a statistical unit 114 is provided as a functional component. The statistical unit 114 is realized by software in the same manner as other functional components. Note that the statistical unit 114 may be realized by hardware in the same manner as other functional components.
Further, the database server 50 implements the function of the statistics storage unit 54.

*** Explanation of operation ***
With reference to FIG. 18, a data recognition process according to the third embodiment will be described.
The processing from step S51 to step S55 is the same as the processing from step S21 to step S25 in FIG.

(Step S56 in FIG. 18: statistical processing)
The statistical unit 114 acquires the content determined to be deficient in step S52 or step S54, and writes it in the statistical storage unit 54. The statistical unit 114 also acquires the writing time to each input field 86 and writes it in the statistical storage unit 54.

  Thereby, the deficiency data and the data regarding the writing time are accumulated in the statistical storage unit 54. For example, data on deficiencies and writing times is analyzed by an office worker or the like, the input format 84 is changed, or an explanation of the input content 85 is added. For example, for the input content 85 with many defects, the description regarding the input content 85 is additionally projected to reduce the defects.

*** Effects of Embodiment 3 ***
As described above, the data input device 10 according to the third embodiment accumulates deficiency data. Thereby, the input format 84 and description can be improved. As a result, the system can be made easier for the user to use.
