The operations of the first and second buttons 114 and 116 will be described in more detail below. The first and second buttons 114 and 116 can function as page turning buttons. When the e-reader device 100 is in the orientation shown in FIG. 9 with the user's right hand holding the extended housing portion 118 of the e-reader device, pressing the second button 116 once presses the displayed book / The text advances one page. Pressing the first button 114 once returns the book / text one page to the previous page. Press and hold the second button 116 to advance multiple pages, and press and hold the second button 116 to advance pages faster. Similarly, long-pressing the first button 114 allows you to go back a plurality of pages, and long-pressing the first button 114 makes it faster to move to the previous page. Press and hold the first button 114 or the second button 116 (fast flip mode) to capture the data and save a large number of flipped pages to the e-reader device 100. This information can be important, for example, in determining whether a student has skipped a section of a textbook or other book.

In addition to turning pages back and forth with buttons 114 and 116, these buttons can be used to control non-book scrolling. For example, if a web page with a plurality of pages is displayed, the buttons 114 and 116 can be used to scroll the page up and down without the user having to use his or her finger on the screen. This allows the user to hold and control the device with one hand instead of both hands. Also, when the e-reader device 100 is displaying a library of books (ie, the library or bookshelf of the e-reader), the buttons 114, 116 allow the user to move the pages of the entire library of the book up and down. You can also use buttons 114 and 116 to scroll through the displayed menu.

Buttons 114 and 116 can also be used when viewing a PDF document / image on the display screen 104. When the display screen 104 does not display the entire page of the PDF document / image, pressing the buttons 114 and 116 changes the part of the PDF that is currently visible instead of changing the page of the PDF document. Can be done. In other words, the buttons 114, 116 allow you to move between different parts of a page of a PDF document instead of flipping through pages in the PDF document to another page. In this mode, the buttons are used to move up and down between small areas within the PDF page. For example, if the upper half of the PDF page is displayed and the lower half of the PDF page is not displayed, pressing the lower button of buttons 114 and 116 will not display the next page. , The bottom half of the PDF page is displayed.

The function of the buttons 114, 116 is related to the orientation of the e-reader device 100, which is detected by the accelerometer. For example, in the e-reader device 100, when the user's left hand is in the direction of holding the expansion housing portion 118 of the e-reader device 100, by pressing the second button 116, a plurality of previous pages / previous pages may be pressed. You can go to the page or scroll up depending on what is displayed. Similarly, by pressing the first button 114, you can move to the next page / next plurality of pages, or scroll down depending on what is displayed. The text / image on the display screen 104 has four different orientations based on the orientation of the e-reader device 100, and the buttons 114, 116 function to jump to the previous page / scroll upwards. Whether it functions to jump to the next page / scroll downward depends on the detected direction of the e-reader device 100.

In an exemplary embodiment, the e-reader device 100 has a screen rotation lock function that can be selected by the user. For example, the user accesses a menu for initiating a user-selectable screen rotation lock feature displayed on the display screen 104 and selects an option that allows the screen to be locked either portrait or landscape. be able to. In an exemplary embodiment, the screen is locked in portrait mode, and when the user swaps hands holding the device 100 (rotates the device 180 degrees), the screen automatically rotates 180 degrees. It remains in portrait orientation. In other words, the orientation of the image on the screen is the same even after changing hands. This is shown in FIGS. 21A and 21C. If the screen is locked to portrait mode and held in the user's right hand (FIG. 21A), the e-reader device 100 is switched to the user's left hand (FIG. 21C) and the screen remains portrait. The displayed screen is in the same orientation as before the hand was brought back (the device is rotated 180 degrees). The landscape orientation is not displayed while the device 100 is rotated (see FIG. 21B). Similarly, if the screen is locked sideways and the user swaps hands holding the device 100 (rotates the device 180 degrees), the screen automatically rotates 180 degrees and remains sideways. The portrait orientation is not displayed while the device 100 is rotated.

FIG. 22 is a flowchart further explaining the screen rotation lock function that can be selected by the user. In step S100, the user accesses a menu for initiating a user-selectable screen rotation lock function. Next, in step S102, the user selects a menu option that locks the screen in portrait (or landscape) orientation. In step S104, when the user rotates the screen 90 degrees, the screen remains portrait (or landscape). In step S106, when the user further rotates the screen 90 degrees (for example, from the orientation of the device of FIG. 21B to the orientation of the device of FIG. 21C) in the same direction as the previous rotation, the screen rotates 180 degrees. The screen is in portrait orientation, and the screen is in the same orientation as before rotation (for example, the orientation of the original image in FIG. 21A).

When the screen rotation lock function is not used and the e-reader device 100 is in the automatic rotation mode and the user moves the device 100 from portrait to landscape, the screen 104 does not immediately switch orientations, but rather to the user. A message is displayed asking if you really want to rotate the screen 104. For example, if the user is lying sideways on the bed and reading in portrait mode, he does not want the screen 104 to switch to landscape mode. In the automatic rotation mode, when the user moves the device 100 from landscape to portrait, a similar message is displayed. Thus, according to the user-selectable screen rotation lock feature, the user can lock the screen to portrait mode (FIG. 21A) so that they are lying sideways on the bed and reading. Occasionally, the screen will be oriented as shown in FIG. 21B. The screen does not automatically switch to landscape mode while the user is lying landscape with the screen locked to portrait mode.
