Slide Bar Handle for Electronic Book Page Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices lack operability when displaying contents with multiple pages, such as electronic books, as they require unique rules for page movement and viewing direction, differing from simple Web page displays.
Innovation Solution
An information processing device and method that includes an operation receiving section and a display image control section, which uses a slide bar with a handle to indicate the current page position, allowing users to navigate through pages via sliding or tilting, and switch between pages using dedicated buttons, mimicking book-reading experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple Web page display method is used, then the display implementation is simple, but the operability is poor for multi-page contents like electronic books
Solution Approach 1:
The patent applies the copying principle by creating a visual replica of a physical book's page-turning experience through the slide bar interface. The handle on the slide bar mimics the physical action of turning pages in a real book, allowing users to interact with electronic book content in a familiar, intuitive manner that replicates natural reading behavior while maintaining simple implementation through standard GUI components.
2Ease of operation
If unique rules for page movement and viewing direction are implemented, then the book-reading experience is improved, but the operation complexity increases
Solution Approach 1:
The slide bar serves multiple functions: it displays the current page position, enables page navigation through handle sliding, provides visual feedback on navigation progress, and works across different device orientations and content types. This multi-functional design achieves natural book-reading interaction without requiring separate control mechanisms for each function, thereby avoiding increased operational complexity.
Solution Approach 2:
The patent transitions from one-dimensional page navigation (simple next/previous buttons) to a two-dimensional interaction model where the slide bar provides both horizontal positioning information and vertical navigation capability. The handle's position along the bar represents page progress, while dragging the handle enables direct navigation to any position, adding a spatial dimension to the interaction that intuitively reflects book structure without complicating operation.
3Loss of information
If a slide bar with handle is displayed, then the page position indication is improved, but the display screen space is reduced
Solution Approach 1:
The patent segments the information display into two parts: the main content area showing the book page and the slide bar showing position information. This segmentation allows the position indication to be displayed in a compact, non-intrusive manner along the edge of the screen, providing continuous page position feedback without significantly reducing the area available for the primary reading content.
Solution Approach 2:
The slide bar is implemented as a thin graphical overlay that provides substantial information (current page position, total pages, navigation control) while occupying minimal screen space. Like a thin film, it delivers functional value with minimal visual and spatial intrusion, maintaining the primary display area for content while adding necessary navigation information.

AI summary
Disclosed herein is an information processing device for displaying contents formed by a plurality of pages according to user operation. The information processing device includes: an operation receiving section receiving an operation of changing a page as an object of display; and a display image control section displaying a slide bar displaying a handle indicating a position of the displayed page on a bar representing the pages of a whole of the contents as a GUI on a display device with an image of the page being displayed. When the operation receiving section receives a user operation of sliding the handle, the display image control section changes display to a page corresponding to a handle reached position. When the operation receiving section receives a user operation on predetermined operating means of an input device, the display image control section changes display to a page serving as a predetermined break.
