E-book Page Image Margin Adjustment for Screen Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional e-book technologies face issues with navigation and space utilization on display screens, making sequential reading frustrating due to the need for horizontal and vertical motion, and poor use of screen space on both large and small displays.
Innovation Solution
A user interface that includes a viewport for displaying e-book pages, which rescales images based on the display area dimensions, adjusts margins to optimize content space, and provides navigation controls to enhance readability and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If e-book pages are displayed with conventional margins and dimensions, then the content is preserved in its original format, but the screen space is not optimally utilized and requires horizontal/vertical motion for navigation
Solution Approach 1:
The system dynamically adjusts the display dimensions and margins of e-book pages based on the available screen real estate. The margin adjustment module modifies margins adaptively, and the image scaling module rescales images to fit the display area, eliminating the need for horizontal/vertical scrolling motion while maximizing screen space utilization.
Solution Approach 2:
The system changes display parameters including margin sizes and image dimensions based on screen availability. The margin adjustment module modifies margin dimensions, and the image scaling module changes image dimensions to match the display area, thereby optimizing screen space without requiring user motion for navigation.
2Area of stationary object
If images are rescaled to fit the display area, then screen space is optimized and navigation is improved, but the original content dimensions are altered
Solution Approach 1:
The system separates the content from the margins and displays only the relevant content portion within the display area. The margin adjustment module identifies and adjusts margins, then the image scaling module scales only the content space, preserving the original content's dimensional relationships while optimizing the display footprint.
Solution Approach 2:
The system extracts the content from the original full-page image by identifying and removing margins. The margin adjustment module determines margin sizes and adjusts them, then the image scaling module scales the extracted content to fit the display area, thereby optimizing screen space while maintaining content integrity.
3Productivity
If margins are adjusted to modify content space, then screen real estate is optimized, but the original page layout is altered
Solution Approach 1:
The system dynamically adjusts margins based on the available display width and height. The margin adjustment module modifies margins adaptively according to screen real estate, allowing optimized content display while maintaining the ability to restore original layouts when needed, thus balancing reading efficiency with layout consistency.

AI summary
A user interface (e.g., a browser window) includes a display area for displaying an image (e.g., a book page image). The image can be rescaled based on the dimensions of the display area and other factors. In some implementations, margins in book page images are adjusted to create additional or less display area.
