Abstract

A method turns pages in an electronic book (e-book) reader. The method includes displaying an e-book as left/right pages and, if a page turn signal is generated, turning a left page or a right page while displaying an action of turning a left page to the right or a right page to the left as if turning pages of a paper book.

2. The method of claim 1 further comprising:

responsive to the page turn signal being continuous, turning pages while displaying an action of continuously turning pages.

3. The method of claim 2 further comprising:

responsive to the page turn signal not being continuous, turning one page while displaying an action of turning one page.

4. The method of claim 2 further comprising:

responsive to detecting the touch button being touched and released, generating the page turn signal;

responsive to detecting the touch button for a threshold time, generating the continuous page turn signal; and

responsive to detecting a drag in a first direction following the continuous page turn signal, generating a variable speed signal for increasing a rate at which pages are turned; and

responsive to detecting a drag in a second direction following the continuous page turn signal, generating a variable speed signal for decreasing a rate at which pages are turned.

8. The method of claim 4, wherein the e-book reader displays the e-book on a touch screen, the method further comprising:

responsive to detecting a touch region displaying the right page being released after touched, generating a page turn signal for turning the right page to the left;

responsive to detecting a touch region displaying the left page being released after touched, generating a page turn signal for turning the left page to the right;

responsive to detecting the touch region displaying the right page being touched for a threshold time, generating a page turn signal for continuously turning right pages to the left;

responsive to detecting the touch region displaying the left page being touched for the threshold time, generating a continuous page turn signal for continuously turning left pages to the right;

responsive to detecting a drag in a first direction following the continuous page turn signal, generating a variable speed signal for increasing a rate at which pages are turned; and

responsive to detecting a drag in a second direction, generating a variable speed signal for decreasing a rate at which pages are turned.

9. The method of claim 4, wherein the e-book reader displays the e-book on a touch screen, the method further comprising:

responsive to detecting a touch in a touch region displaying the right page, a release after the touch, and a drag left within a threshold time, generating a page turn signal for turning one right page to the left;

responsive to detecting a touch in a touch region displaying the left page, and a release after the touch, and a drag right within the threshold time, generating a page turn signal for turning one left page to the right;

responsive to detecting a touch and drag within the threshold time after the touch in the touch region displaying the right page, generating a continuous page turn signal for continuously turning right pages to the left;

responsive to detecting a touch and drag within the threshold time after the touch in the touch region displaying the left page, generating a continuous page turn signal for continuously turning left pages to the right;

responsive to detecting a drag left following generation of the continuous page turn signal for continuously turning the right pages to the left, generating a variable speed signal for increasing a rate at which pages are turned; and

responsive to detecting a drag right following the continuous page turn signal for continuously turning left pages to the right, generating a variable speed signal for increasing a rate at which pages are turned.

10. The method of claim 4, wherein the e-book reader displays the e-book on a Liquid Crystal Display (LCD), and comprises a left and right jog keys at the left and right of the LCD,

wherein the left jog key is used for turning the left page to the right, and the right jog key is used for turning the right page to the left,

the method further comprising:

responsive to detecting one of the left and right jog keys being released after pressed, generating the page turn signal;

responsive to detecting one of the left and right jog keys being pressed for a threshold time, generating the continuous page turn signal; and

responsive to detecting one of the left and right jog keys moving in a first direction following the continuous page turn signal, generating a variable speed signal for increasing a rate at which pages are turned; and

responsive to detecting one of the left and right jog keys moving in a second direction, generating a variable speed signal for decreasing a rate at which pages are turned.

11. The method of claim 4, wherein the e-book reader displays the e-book on a Liquid Crystal Display (LCD), and comprises a left/right movable jog key associated with the LCD,

responsive to detecting the jog key being released within a threshold time after moving left, generating a page turn signal for turning the left page to the right;

responsive to detecting the jog key being released within the threshold time after moving right, generating a page turn signal for turning the right page to the left;

responsive to detecting the jog key moving to one of the left and right for the threshold time, generating a continuous page turn signal for continuously turning pages; and

responsive to detecting movement of the jog key to one of the left and right increasing following generation of the continuous page turn signal, generating a variable speed signal for increasing a rate at which pages are turned.

12. The method of claim 4, wherein the e-book reader displays the e-book on a Liquid Crystal Display (LCD), and comprises a left and right dome keys including a pressure sensor,
