Although the history holding unit 6, the browsing degree calculation unit 7, and the output processing unit 8 are provided and are connected by communication to configure the system, the present invention can be implemented not only in this configuration but also in other configurations.

  Further, in this example, the browsing detection unit 5 is configured by executing the document element browsing detection program according to the present invention using hardware resources such as an arithmetic processing unit (CPU) and a memory included in the computer. However, it may be configured by a dedicated electronic circuit. In this example, the browsing history holding unit 6 is configured by executing the document element browsing history recording program according to the present invention using hardware resources provided in the computer. However, the browsing history holding unit 6 is configured by a dedicated electronic circuit. May be. Further, in this example, the browsing degree calculation unit 7 and the output processing unit 8 are configured by executing the document element browsing degree analysis program according to the present invention using hardware resources provided in the computer. You may comprise by the electronic circuit of.

The document holding unit 1 holds document data, and provides corresponding document data to a requesting information processing terminal in response to a request from the information processing terminal.
In this example, document data including a plurality of document elements is handled, and each document element in the document and identification information of the document element are recorded in the document data in association with each other.

The display processing unit 2 performs display processing for generating a document image based on the document data received from the document holding unit 1 and displaying the document image on the screen 3.
The screen 3 is configured by a display device such as a liquid crystal display, and displays a document image according to display processing by the display processing unit 2.
The operation reception unit 4 receives an operation input from a viewer using an input device such as a keyboard / mouse.

  The display processing unit 2 may display a part of the document when the entire document cannot be displayed at once in the display area, for example, when the number of pages of the document is large or the display area of the liquid crystal screen is small. Display processing for. Then, in response to the operation input for changing the document part to be displayed being received from the viewer by the operation receiving unit 4, display processing of the document part instructed by the operation input is performed.

  The browsing detection unit 5 regards the operation input performed by the viewer to change the document part to be displayed as a browsing operation, and displays the document element (the display processing unit 2 performs display processing) of the document part that is the target of the browsing operation. Document element).

  The browsing history holding unit 6 accumulates and holds the browsing history according to the detection of the document element by the browsing detection unit 5. As shown in FIG. 2, the browsing history includes “document ID” that is identification information of document data, and “document element” that is identification information of a document element subjected to a browsing operation in the document data. “ID” and “viewing time”, which is the time when the document element was displayed, are recorded as a set.

  The browsing degree calculation unit 7 calculates, for each document element, browsing degree information indicating the degree to which the document element has been browsed based on the browsing history. In this example, the total browsing time obtained by tabulating the browsing time for each document element is calculated as browsing frequency information. For example, the browsing frequency that is the number of records in the browsing history for each document element may be calculated as browsing frequency information. .

  The output processing unit 8 provides the degree-of-view information for each document element to a display device such as a liquid crystal display provided in the analysis server, for example, and outputs it to a printing apparatus with which the analysis server communicates. Print out.

FIG. 3 shows an example of a document display screen 30 that is displayed and output on the screen 3 by the display processing by the display processing unit 2. In the document element browsing degree analysis system of this example, a document image is displayed on the document display screen 30. I'm drawing.
The document display screen 30 is provided with a display part change receiving unit 31 (operation receiving unit 4) for receiving an operation input for changing a document part to be displayed from a viewer. The document portion to be displayed is changed according to the movement. In addition to the display part change instruction unit 31, the change of the document part to be displayed can be realized by other means such as receiving and changing the designation of the display target page.

  In the document element browsing degree analysis system of this example, as a document element to be analyzed, “chapter” and “section” indicated by reference numeral 33 in FIG. The document element in units such as "" and "photo" is detected. However, as will be described later, the document element in "word" units indicated by reference numeral 35 can also be detected.

Next, the browsing operation detection process according to this example will be described in detail.
For example, when the viewer performs an operation of moving the display part change instruction unit 31 downward while a part of the document is displayed on the document display screen 30, the operation content (movement direction and movement amount) is displayed. The processing unit 2 is notified.

  Upon receiving the notification of the operation content, the display processing unit 2 determines that the operation input for changing the document part to be displayed has been made, and specifies and displays the document element of the part newly displayed by the change from the document data. Processing is performed, and an image of the document element is drawn on the document display screen 30. At this time, the browsing detection unit 5 detects the document element as a target of the browsing operation, and temporarily stores the detected time on the memory as a browsing start time.

  After that, for example, when the operation of moving the display part change instruction unit 31 further downward is performed and the document part related to the document element is excluded from the display target, the browsing detection unit 5 determines the time when the display part change instruction unit 31 is excluded from the display target. Detect as browsing end time. Then, the browsing detection unit 5 calculates the browsing time of the document element (the time during which the document element was displayed) from the browsing start time and the browsing end time once stored in the memory, and the data identification information and It is provided to the browsing history holding unit 6 together with the document element identification information, and is stored and held as a browsing history.

  That is, in the document element browsing degree analysis system of this example, since it can be estimated that the document element that was actually displayed has been viewed by the viewer, it is displayed according to the operation input (viewing operation) that changes the document part to be displayed. The history of the document element of the selected part is accumulated and held as a browsing history.

Here, the display processing unit 2 of this example eliminates wasteful processing by performing display processing on the condition that the document element has become a display target beyond a certain time, and the calculated browsing time is the above certain time. In the following case, since it is not actually displayed, in this case, it is regarded that the browsing has not been performed, and the accumulation of the browsing history is stopped.
It should be noted that the browsing history may be accumulated only when the actually displayed time is equal to or greater than a predetermined value so that the browsing is not performed when the display is immediately removed from the display target.

  For the document elements of the document portion displayed on the document display screen 30 from the start of document display, the browse time is calculated with the start of document display as the browse start time. For the document element of the document portion displayed at the end of the document display on the document display screen 30, the browse time is calculated with the end of the document display as the browse end time.

Further, the browsing detection unit 5 of this example regards an operation input for changing a document part to be displayed as a browsing operation and detects the target document element, but may detect it based on other browsing operations. .
For example, when an operation input for enlarging and displaying a document element is received from a viewer, the operation input is regarded as a browsing operation, the enlarged and displayed document element is detected, and the time when the enlarged display is performed is set as the browsing time. It may be calculated and recorded in the browsing history. Further, by acquiring and recording detailed information related to browsing such as the magnification of the enlarged display and the range of the enlarged display, a more detailed analysis can be performed.

  Also, for example, as shown in FIG. 4 (a), the document element is initially displayed in a portion where the document element corresponds to the display destination, and the document element is not disclosed, and an operation input instructing the disclosure from the viewer is accepted. As shown in FIG. 4B, the document element is made public, the operation input is regarded as a browsing operation, the published document element is detected, and the display target is displayed from the published time. It is possible to calculate up to the time when it is outside as the browsing time and record it in the browsing history.

FIG. 5 shows an output example by the output processing unit 8.
In the output example of the figure, a table of contents in which titles attached to each document element such as chapters and sections in the document are arranged in a list format is output, and the browsing degree of the document element corresponding to each title is viewed. As a histogram representing the width according to the degree information, it is output on the right side in association with each title. For this reason, the analyst can grasp the browsing degree for each document element at a glance. In this example, the total browsing time for each document element is calculated and output as browsing degree information, but the browsing count for each document element may be calculated and output as browsing degree information.

FIG. 6 shows a system configuration according to another embodiment of the present invention.
The document element browsing degree analysis system shown in the figure includes a line-of-sight tracking unit 9 in addition to the processing units included in the document element browsing degree analysis system shown in FIG. The document holding unit 1, the display processing unit 2, the screen 3, the operation receiving unit 4, the browsing history holding unit 6, and the browsing degree calculation unit 7 are the same as the processing units described with reference to FIG. Omit.

The line-of-sight tracking unit 9 identifies the position on the screen 3 where the viewer is turning his / her line of sight by using a known technique for measuring and tracking the movement of a person's head and eyes with a video camera or the like. Is notified to the browsing detection unit 5.
The browsing detection unit 5 detects the document element displayed at the position based on the position notified from the line-of-sight tracking unit 9 and accumulates it in the browsing history holding unit 6 as a browsing history.

  That is, in order to detect a document element (a document element to which the line of sight is directed) as an object of the browsing operation, an operation in which the viewer turns the line of sight toward the document element is regarded as a browsing operation. In addition to document elements such as graphics and photographs, unit document elements such as “words” having a finer granularity can be detected.

  The output processing unit 8 can also perform output as shown in FIG. 7 according to the fact that the browsing detection unit 5 can detect a finer unit of document elements, and analysis from another viewpoint is also possible.

  FIG. 7A shows an example in which a document is output by changing the display mode such as the background color and the character size of the word according to the viewing degree. You can see how much attention has been gained while looking at the actual document. According to the figure, the background colors of the word 41 and the word 42 are different from others, and it can be seen that these words attracted attention. Further, since the background color of the word 42 is darker than the background color of the word 41, it can be seen that the word 42 attracted more attention than the word 41.

  FIG. 7B shows an example in which a part that has attracted attention in the document is specified based on each browsing degree of the document element, and the document is output with the background color of the part different from the others. The analyst can also grasp a portion that easily attracts the viewer's interest on the structure and layout of the document. According to the figure, the central part of the portion 43 has the darkest background color, and the background color becomes lighter as it moves away from it, so the viewer is interested in the central portion of the portion 43 and focuses on the vicinity. You can see that
