Region of Interest Selection for Electronic Document Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic documents designed for standard desktop displays often become unusable or difficult to navigate when displayed on devices with different screen sizes and resolutions, such as handheld devices or televisions, due to inadequate handling of layout and content modifications.
Innovation Solution
A method for selecting a region of interest within an electronic document and displaying it in a manner adapted to the device's capabilities, involving analysis of the document layout, user input, and stepwise changes in resolution and positioning to ensure the region fits within the display, allowing for zooming and panning while maintaining readability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the document is displayed by removing or modifying content and layout to fit the screen, then the document can be displayed on devices with different screen sizes, but the page may become unusable or the user may have difficulties navigating within the document
Solution Approach 1:
The patent divides the electronic document into multiple regions of interest, each representing a meaningful section or component of the document. This segmentation allows the system to selectively display and navigate through specific regions rather than treating the entire document as a single unit, thereby maintaining usability while adapting to different display sizes.
Solution Approach 2:
The patent introduces a hierarchical dimension to document navigation by organizing regions of interest at different levels. Users can navigate from a high-level overview of the entire document down to specific regions, adding a dimensional layer to navigation that works effectively across various screen sizes without compromising usability.
2Adaptability or versatility
If the document is resized or layout is changed to fit smaller screens, then the document can be displayed on handheld devices, but the user may not recognize the document or has difficulties navigating within it
Solution Approach 1:
The patent performs preliminary analysis of the document structure before display to identify meaningful regions of interest and their hierarchical relationships. This pre-processing ensures that when the document is adapted to different display sizes, the fundamental structure and recognizable elements are preserved, maintaining document recognition across devices.
Solution Approach 2:
The patent applies different display and navigation strategies to different regions of the document based on their specific characteristics and importance. Rather than uniformly resizing or reformatting the entire document, the system preserves the visual and structural qualities of key regions that are essential for document recognition while adapting other areas to fit the display.
3Stability of the object's composition
If standard display methods are used for electronic documents on devices with limited display area, then the document layout is preserved, but the document becomes difficult to navigate and may be unusable
Solution Approach 1:
The patent implements dynamic navigation capabilities that allow users to interactively explore different regions of interest within the document. The system dynamically adjusts the displayed region based on user selections and device characteristics, enabling effective navigation while preserving the overall layout integrity of the document structure.

AI summary
A method is provided for selecting a region of interest in an electronic document and displaying the selected region in a manner that is adapted to the capabilities of a display. The method may comprise such steps as loading a document, selecting a position within said document, analyzing the layout of the document in order to identify a region of interest containing said position, and displaying said region of interest on said display in a manner that aligns the region of interest with a window of said display. Also described is a device configured to perform the method and a computer program product including instructions for performing the method on a computing device.
