The electronic document may be registered in the read table 150 as a read electronic document. In this case, after the detection unit 138 detects that the user has viewed all the emphasis target parts included in the electronic document, the user can confirm the content of the electronic document again. Therefore, for example, it is more suitable for a user who is reading, such as reading only the keyword once and reading it to the end, and returning and confirming only the part of interest.

  In addition, when the detection unit 138 detects that the user has viewed all the emphasis target parts included in the electronic document, the already-read registration unit 140 may notify the external management apparatus via the network 102 to that effect. Good.

  FIG. 5 is a data structure diagram showing an example of the read table 150. The already-read table 150 stores an electronic document name that is a file name of the electronic document, a read flag, and a completion time in association with each other. The read flag is an index indicating whether the electronic document is read or not, and is updated by the read registration unit 140. The reading completion time is a time corresponding to the time when the electronic document is read by the user when the already-read flag is set in the electronic document. The reading completion time may be, for example, the time when the read flag is set by the read registration unit 140.

Returning to FIG.
The electronic document generation unit 144 receives an input from the input unit 104 such as a keyboard by the user, and generates an electronic document.
The important area designation unit 146 causes the monitor 106 to display the electronic document generated by the electronic document generation unit 144. The important area designation unit 146 receives designation of an important area for the displayed electronic document. The important area is a part reflecting the intention of the creator of the electronic document, such as an important part of the electronic document that the user wants the transmission target person to see.
The important area designation unit 146 receives an input of a transmission target person list of the electronic document from the user. The important area designating unit 146 also accepts information indicating the version of the electronic document to be transmitted for each transmission target person. The version of the electronic document is, for example, version 1 for sending information on important areas attached to the electronic document and version 2 for sending such information without attaching the information to the electronic document. The important area specifying unit 146 registers the electronic document generated by the electronic document generating unit 144 in the version storage unit 154 in association with the transmission target person and the version specified for the transmission target person.

  FIG. 6 is a data structure diagram illustrating an example of the version storage unit 154. The version storage unit 154 stores the transmission target person and the version of the electronic document in association with each electronic document generated by the electronic document generation unit 144.

  Returning to FIG. The display confirmation unit 148 inputs the electronic document in which the important area is designated by the important area designation unit 146 to the electronic document acquisition unit 132. Thus, the user can know how the electronic file generated by the electronic document generation unit 144 and whose important area is specified by the important area specifying unit 146 is displayed on the transmission target side.

In this way, by specifying the important area, it is possible to determine whether the electronic document has been read in a form that more reflects the intention of the creator of the electronic document.

  For the electronic document confirmed by the display confirmation unit 148, the version selection unit 152 selects, for each transmission target person, the form of the electronic document to be transmitted based on the version registered in the version storage unit 154. Thereby, the degree of the read determination can be controlled for each transmission target person.

  In the above-described embodiment, examples of the storage device are a hard disk and a memory. Based on the description in this specification, each unit is realized by a CPU (not shown), an installed application program module, a system program module, a memory that temporarily stores the contents of data read from the hard disk, and the like. It is understood by those skilled in the art who have touched this specification that they can do this.

  The operation of the read determination device 100 having the above configuration will be described. FIG. 8 is a flowchart showing a series of processes in the read determination device 100. Here, it is assumed that the page transition mode is used in the display control unit 136. The electronic document acquisition unit 132 acquires an electronic document from the storage device 142 (S602). The keyword extracting unit 134 extracts an emphasis target portion from the acquired electronic document according to the fast reading support algorithm (S604). When displaying one page of the acquired electronic document on the monitor 106, the display control unit 136 highlights and displays the extracted highlight target portion (S606). The detection unit 138 detects that the user has viewed the emphasis target portion included in one page of the electronic document displayed on the monitor 106 (S608). The detection unit 138 continues the detection process until it is detected that the user has viewed all the highlight target portions included in one page of the electronic document displayed on the monitor 106 (N in S610). The detection unit 138 detects that the user has viewed all the emphasis target portions included in one page of the electronic document displayed on the monitor 106 (Y in S610), and also detects the electronic document displayed on the monitor 106. If one page is not the last page (N in S612), the page of the electronic document displayed on the monitor 106 is advanced, and the process returns to step S606. When one page of the electronic document displayed on the monitor 106 is the last page (Y in S612), the read registration unit 140 sets a read flag corresponding to the electronic document in the read table 150 (S614).

  According to the read determination device 100 according to the present embodiment, when an electronic document is displayed on the monitor 106, the highlight target portion is emphasized, and it is detected that the user has seen the highlight target portion. Furthermore, the electronic document is registered as already read on condition that it is detected that the user has viewed the emphasis target portion. Therefore, since the user cannot read the electronic document as long as he / she does not look at the emphasis target portion, the reliability of the read determination by the read determination device 100 is increased. In addition, by using the fast reading support algorithm in the keyword extraction unit 134, it is possible to allow the user to perform rapid reading training simultaneously with the already-read determination.

  Further, in the page transition mode, the display control unit 136 detects that the user has viewed the highlight target portion included in the page displayed in the electronic document display area of the monitor 106, and displays the next page on the monitor 106. Display. In the scroll mode, the display control unit 136 permits further scrolling when it is detected that the user has seen the emphasis target portion included in the disappeared line. Therefore, in any mode, when moving from the display portion including the highlight target portion to the next display portion, the user is required to click or gaze at the highlight target portion. As a result, it is limited to skip a page including the emphasis target portion or to scroll quickly without reading the emphasis target portion. Thereby, the reliability of the read determination by the read determination device 100 is further improved.

  Further, in the page transition mode, the display control unit 136 monitors the next page when it is detected that the user has viewed all the highlight target portions included in the page displayed in the electronic document display area of the monitor 106. 106. Therefore, for each page of the electronic document, the user needs to read through all the highlight target portions included in the page. As a result, when the user looks through all the highlight target parts included in the electronic document, the electronic document is read. Thereby, the reliability of the read determination for each page and the reliability of the read determination for the entire electronic document are further improved.

  In the scroll mode, the display control unit 136 restricts further scrolling when an extinction line includes an emphasis target portion that has not yet been detected by the user. Therefore, it is possible to prevent the highlighted target portion once displayed from disappearing from the display without being seen by the user. Thereby, the reliability of the already-read determination is further improved.

  The configuration and operation of the read determination device 100 according to the embodiment have been described above. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to each component and combination of processes, and such modifications are within the scope of the present invention.

  In the embodiment, in the page transition mode, the display control unit 136 determines that the detection unit 138 detects that the user has viewed all the highlight target parts included in the page displayed on the monitor 106 from the user. Although the case where the acceptance of the page progress instruction is restricted has been described, the present invention is not limited to this. For example, in the page transition mode, the display control unit advances the page from the user until the detection unit 138 detects that the user has seen at least one highlight target portion included in the page displayed on the monitor 106. The acceptance of instructions may be restricted. Even in this case, since the user is restricted from skipping the page of the electronic document, the reliability of the already-read determination is improved.

  In the embodiment, when the read registration unit 140 detects that the user has viewed all the emphasis target parts included in the electronic document, the read registration unit 140 sets the electronic document as a read electronic document to the read table 150. However, the present invention is not limited to this, and as a condition for registering the electronic document as read, the detection unit 138 detects that the user has viewed at least one emphasis target portion included in the electronic document. May be adopted. Even in this case, since the electronic document is not read as long as the user does not look at the at least one emphasis target portion, the reliability of the read determination is improved.

  Although the present invention has been described based on the embodiments, the embodiments merely show the principle and application of the present invention, and the embodiments are defined in the claims. Needless to say, many modifications and arrangements can be made without departing from the spirit of the present invention.
