E-book Display Area Adjustment for Text Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic books, especially those in automatic reflowable format, often face issues with text being cut off at the edges of the screen, requiring frequent page turns to read complete sentences or paragraphs due to limited display area on electronic book devices.
Innovation Solution
An electronic book device with a processor that adjusts the display area based on user input, using tags to divide text into units like sentences or paragraphs, allowing for whole or partial adjustments to fully display content, including options to show a previous or next page, or to emphasize cut-off text.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automatic reflowable format is used to optimize text display according to screen size, then text layout adapts to screen dimensions, but sentences or paragraphs are frequently cut off at the upper end or lower end of the screen requiring page turns
Solution Approach 1:
The patent segments the display area adjustment into two distinct modes: partial adjustment for sentences/paragraphs and whole adjustment for pages. This segmentation allows the system to handle different reading scenarios appropriately, resolving the contradiction by enabling sentence-level control without sacrificing overall page navigation capability
Solution Approach 2:
The patent implements dynamic adjustment of display area based on user input (touch values). The system can switch between different adjustment granularities (sentence, paragraph, or full page) depending on the user's gesture, making the display behavior adaptive and context-dependent rather than fixed
2Stability of the object's composition
If fixed layout format is used to maintain character size and font, then text appearance remains consistent, but characters are displayed in small sizes on small screens
Solution Approach 1:
The patent makes the display area dynamic by allowing adjustment based on user input. While the fixed layout maintains text appearance consistency, the display area can be partially or wholly adjusted to show more content, resolving the contradiction between consistent formatting and adequate visibility on small screens
3Productivity
If limited display area is used to fit content on screen, then screen space is efficiently utilized, but frequent page turns are required to read complete sentences or paragraphs
Solution Approach 1:
The patent applies partial adjustment of the display area rather than requiring full page turns. By showing only the portion of text that needs to be visible (partial action), the system reduces the time and effort required for navigation while maintaining efficient screen space utilization
Solution Approach 2:
The patent segments the navigation action into finer granularities (sentence-level, paragraph-level) in addition to full page turns. This segmentation allows users to make smaller, more precise adjustments to the display area, reducing unnecessary scrolling or page turns and thus reducing time loss

AI summary
Provided is a method of adjusting a display area of electronic book contents. The electronic book contents include tags that divide texts of the electronic book contents into sentence or paragraph units. The touch input of a user includes at least one of touch region, gesture type, and gesture direction. The processor wholly adjusts the display area of the electronic book contents such that a previous or next page is displayed in accordance with a first touch value, and partially adjusts the display area of the electronic book contents using the tags of the electronic book contents such that a sentence at an upper end or at a lower end or a paragraph including the sentence is fully displayed in accordance with a second touch value.
