If you touch the tag of "Accommodation" with the right finger at the same time, the first page with the information of "Accommodation in South India" is displayed directly by one operation. I have.

When the information of “South India Accommodation” is spread over a plurality of pages, the information described on the next page and subsequent pages can be read by inputting a page turn as shown in FIG. Can be.

(4) Page Turning, Bookmark Processing, etc. Next, a specific example of turning pages in the electronic book of the present embodiment will be described.

Page Turning Input Operation In the electronic book of the present embodiment, since various operations are input as finger operations on the screen, there are almost no operation input buttons or the like on the housing. Also, the screen on which the book contents are displayed is characterized in that there is almost no operation input mark on the screen (see FIG. 3).

In the present embodiment, by setting travel information software in an electronic book, the user can use the same user-friendly user as referring to a travel guidebook, and can display the actual book on a screen as shown in FIG. You can refer to the same content as the page.

When the user wants to refer to the next page, the user traces the information display area on the screen from left to right with his index finger as in turning a page of a paper book, as shown in FIG. The display screen is updated to the contents of the next page as if the page were turned.

At this time, it is necessary for the user to move the finger in the lateral direction so as to rub the index finger or the like or touch the screen with a certain strength. In the present embodiment, in order to distinguish the page turning input from other inputs, when the finger is touching the screen with a predetermined area or more and a predetermined pressure value or more and moving in the horizontal direction, This is because it is determined that the turning has been input.

The direction of page turning and the elevation of a page differ depending on whether it is written vertically or horizontally as in an actual book.
Therefore, in the case of a vertically written book, the page advances from right to left, so when the finger is moved as shown in FIG. 14, the next page is turned, but in the case of horizontal writing, the previous page is turned. Conversely, in the case of a vertically written book, tracing from right to left with the index finger turns the previous page contrary to FIG. 14, but in the case of horizontal writing, the next page is turned.

As described above, since the user can perform page turning input with the same feeling as handling a normal book, it is possible to provide a human interface that is easy to learn and easy to use.

At the time of page turning input, as shown in FIG. 14, an image in which a page is being turned may be displayed in accordance with the movement of the finger, but it may be configured to switch directly to the previous page screen or the next page screen.

Continuous page turning input operation As shown in FIG. 15, when the user keeps touching images (hereinafter, referred to as “book thickness”) 240 and 242 imitating “book thickness” for a predetermined time or more, the page is displayed. It flips continuously. At this time, if the user changes the touching strength, the speed of turning the page can be changed. That is, the user can increase the speed of turning the page by touching more strongly. You can also slow down the page turn by reducing the intensity of the touch. When the user finds the page he / she wants to read, he / she can release the hand from the “thickness of the book” to stop the continuous page turning and position the display screen on the page.

As in the case of the page turning described above, the elevation of the page differs depending on the vertical writing or the horizontal writing. Therefore, in the case of a vertically written book, if the thickness of the book on the left end is kept touching as shown in FIG. 15, the pages are continuously turned in the next page direction. Turn over. Conversely, in the case of a vertically written book, FIG.
Conversely, if you keep touching the thickness of the book on the right end, the pages will be turned continuously in the previous page direction, but in the case of horizontal writing, the pages will be turned continuously in the next page direction.

As described above, since the user can perform page turning input with the same feeling as handling a normal book, it is possible to provide a human interface that is easy to learn and easy to use.

At the time of continuous page turning input, as shown in FIG. 15, an image in which a page is turned in accordance with the movement of a finger may be displayed, but it is directly displayed on the previous page screen or the next page screen every predetermined time. The configuration may be switched.

In addition, an image sound which can be associated with a page turning sound such as “para-para-para” may be output in response to page turning.

Bookmark Insertion / Reference Operation Next, the bookmark function of the present embodiment will be described. Just as a bookmark is inserted at a place to be referred to again during normal reading, a bookmark can be added to a page to be referred to again in the present embodiment.

As shown in FIG. 16, by dragging the arrow portion 260 and tracing the finger to the bottom of the screen, a bookmark can be inserted into the page. That is, after the above operation, FIG.
As shown in FIG. 7, a bookmark mark 270 is displayed on the screen.
