Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic page turning device for electronic documents.

[Conventional technology]

Conventionally, when displaying the corresponding page of a stored electronic document, or displaying the corresponding page of a searched electronic document, it was necessary to enter the corresponding page number from the keyboard. I am doing it. Furthermore, there are also methods in which displaying the previous page or next page is achieved by pressing specific keys corresponding thereto.

On the other hand, as an input method that does not use a keyboard, there is a method that uses a pointing device such as a mouse or a trackball. .

[Problem that the invention seeks to solve]

However, unlike flipping through paper documents, using the keyboard input method for electronic documents requires indirect and discrete operations, which increases the psychological burden on users. . As an alternative to such keyboard input, a pointing device such as a mouse can be considered, but as shown in the above-mentioned published patent, its use is limited to operations such as menu selection.

The first object of the present invention is to solve these problems and visually display electronic documents by using a pointing device such as a mouse and a page position display corresponding to the thickness of a paper document. The object of the present invention is to provide an electronic page turning device that can be operated directly and continuously.

The second object of the present invention is to display page positions in such a way that the accuracy of specifying pages close to the currently displayed page is high, and the accuracy of specifying pages far from the currently displayed page is low, especially for a large amount of electronic documents. It is an object of the present invention to provide an electronic page turning device in which the width of the pages is kept within a certain range and operability is improved.

[Means for solving problems]

The electronic page turning device of the present invention includes a document storage means that stores an electronic document, a pointing device that can specify any position on the display screen, and all pages of the electronic document, the current page, and the pages before and after it. page position display creation means for creating data that is displayed graphically and by linearly or non-linearly changing the position specified by the pointing device; and displaying the display output from this page position display creation means on a screen. The device includes a display means, and a control means that controls data from the document storage means according to the pointing device and supplies the data onto the display means via the page position display means.

[Effect]

According to the configuration of the present invention, the page position display is graphically displayed on the display means in accordance with the thickness of the document.

The thickness of this document refers to the number of pages of the document. When a pointing device symbol (mouse cursor in the case of a mouse) is indicated within the page position display, the control means immediately calculates the page number corresponding to that position based on the current position on the display means. , the updated page number can be displayed in real time.

Therefore, the user can point to a page by simply moving the pointing device, and then can open the page by simply expressing an intention to open the page (by pressing a button in the case of a mouse). Improves operability. Based on the page number obtained in this way, the corresponding document is retrieved from the electronic document storage means and displayed on the display means, thereby completing simple page turning of the electronic document.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention. The pointing device 1 of this embodiment is, for example, a device such as a mouse or a trackball, and can be moved arbitrarily on the display screen, and can also detect the position (coordinates) at that time. . The digitized document storage means 2 is a means for storing generally digitized documents such as code data, graphic data, or image data outputted by a word processor, and also uses a search system to find a corresponding document from a large amount of data. It can also be regarded as a means for storing data after taking it out; for example, an optical disk device is composed of a magnetic disk device or the like.

Further, the linear page position display creation means 3 has a size proportional to the number of pages of the electronic document storage means 2, and has a size proportional to the number of pages of the electronic document storage means 2.
This is a means for creating a diagram as shown in Figure (a). This figure shows a case where seven pages of documents are displayed in a horizontal bar graph on the display screen 20. That is, frames for seven pages are prepared on the bar graph, and the current page (5), the previous page, and the next page are displayed in different colors. Also, the current page (5) is displayed on the left side of this bar graph, and the first page number (1), the last page number (7), and the page number on the mouse cursor (3) are displayed above the bar graph. .

Furthermore, the control means 4 controls the linear page position display creation means 3.
Display the page position indication obtained by , and when the cursor of pointing device 1 enters this page position indication, immediately calculate the corresponding page number from that position,
The corresponding page is retrieved from the electronic document storage means 2 and displayed. The means for actually displaying this is the display means 5, which is constituted by a normal CRT display or the like.

FIG. 4 is a flowchart representing a detailed example of the control means 4 when the pointing device 1 is implemented as a mouse. First, the position (coordinates) of the mouse cursor is input in the mouse cursor position input step. Next, in a page number conversion step, the position of the mouse cursor is converted to a corresponding page number. Here, since a linear page position display is used, the conversion formula to a page number is an integer value obtained from the following formula.

After that, this page number is actually displayed in a page number display step 13 to inform the user, and the user can make a decision interactively.
If the desired page is found, the user can simply click (press) the mouse button and give instructions to turn the page. Otherwise, sequentially enter the mouse cursor position step 1
Return to step 1 and repeat the same procedure.

If it is determined in the click determination step 14 that the page has been clicked, the page position display and the new page number display are updated in the new page display step 15. Finally, in a corresponding document display step 16, the actual document is displayed, and page turning of the electronic document is completed.

FIG. 2 is a block diagram showing a second embodiment of the present invention. This embodiment differs from the first embodiment in that a non-linear page position display is used instead of the linear page position display creation means 3. This is because the display creation means 6 is used. This is, for example,
This is a means to create a diagram as shown in Figure 3 (b) in the same way as Figure 3 (a), and the width of the page position display is constant,
Areas of pages close to the current page area (previous page, current page, and next page in the figure) are displayed large, and areas of pages far away (pages 2 to 44 and pages 47 to 79 in the figure) are displayed small. In this figure, the current page number (46) is displayed on the left side of the bar graph, the first page (1), the last page (80), and the page number under the mouse cursor (1).
5) is displayed above the bar graph. Page (80
Operations such as enlarging the area of page) also belong to the scope of the non-linear page position display creation means 6.

The flowchart shown in FIG. 4 is also similar, but the conversion formula to a page number by the page number conversion step 12 is different. Now, the page position display width.

Assuming that the total number of pages is N and the current number of pages is n (]≦1≦N), the page number p corresponding to the mouse cursor position is
For example, it is expressed as follows.

1) When 1≦X≦n-1, p=ax 2) When n-1<x≦n+l, L-a (N-2> (L-aN) (n-1) 3)
When n+1<x≦N, p = a(x-N)+, where a is a constant that becomes 0 x a -.

Here, in reality, the obtained p is converted into an integer and is regarded as the corresponding page number. When created in this manner, the current page n of the interview is expressed with high precision, while other pages are expressed with low precision, and even when the total number of pages N is large, it is possible to easily turn the previous or next page.

Further, combinations of these embodiments and embodiments in which pages can be turned continuously while the mouse button is pressed can also be easily inferred from the present invention.
All of these belong within the scope of the present invention.

〔Effect of the invention〕

As explained above, according to the present invention, by visually displaying the page position proportional to the thickness of the document (the number of pages) when turning the pages of an electronic document, it is possible to easily and directly and continuously Since the user can make a specification and can also perform the operation interactively, it has the effect that even if an incorrect specification is made, it can be quickly re-specified.

Further, according to the present invention, in addition to the first embodiment, the second embodiment enables adaptive operation according to the frequency of user specifications by changing the precision of page specification, and in addition, It has the versatility of being applicable even when the number of pages is large.
