Digital Book Graphical Navigator

摘要

This touch-screen computer graphical user interface navigation mechanism consists of a horizontally oriented list of miniature images representing pages in a digital book. From any page, the user can quickly navigate to any other page in the book by performing a two-finger tap, swiping the list left or right, and selecting an image to go to that page. When the book contains chapters, a secondary list is used to navigate through the book chapters. The miniature images in the lists are displayed in the same order as the pages and chapters in the book, from beginning to end. The user swipes left or right, swiftly or slowly, forward or backward, to the desired page. The user selects the miniature image to navigate to the page. With the two-finger tap and these sliding lists, the user can quickly and easily navigate through the chapters and pages of a digital book.
