DOI Visibility Protection via Overlap Detection and Content Hiding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying Digital Object Unique Identifiers (DOIs) on web pages often require two devices, where other information, such as cursors or popup windows, can obscure the DOI, leading to failed scanning due to incomplete or obscured visibility.
Innovation Solution
A terminal device with a monitoring module to detect overlapping display positions of DOIs and other information, using a processing module to hide overlapping content, such as adjusting transparency or hiding specific areas, ensuring the DOI is clearly visible for scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If other information (cursors, popup windows) is displayed on the webpage, then information completeness is improved, but DOI visibility deteriorates when they overlap
Solution Approach 1:
The patent extracts the harmful overlapping portion of other information that obscures the DOI and removes it from the display. When detection determines that other information overlaps with the DOI position, the system selectively hides or removes only the overlapping portion, allowing the DOI to remain visible while preserving the rest of the information content.
Solution Approach 2:
The patent applies different display qualities to different regions of the webpage. The DOI region is given priority visibility (protected from obscuration), while other regions can display additional information. This local differentiation ensures that the DOI remains clearly visible while other information is displayed in non-overlapping areas.
2Adaptability or versatility
If two devices are used (one for display, one for scanning), then DOI scanning capability is improved, but device complexity increases
Solution Approach 1:
The patent makes the terminal device that displays the webpage also capable of scanning the DOI using its camera. The device performs dual functions: displaying the webpage with the DOI and capturing the DOI image through the camera for recognition. This eliminates the need for a separate scanning device while maintaining full DOI scanning capability.
Solution Approach 2:
The patent combines the webpage display function and DOI scanning function into a single terminal device. The display terminal uses its built-in camera to capture the DOI, merging what were previously separate functions performed by different devices into one integrated system.
3Ease of operation
If DOI is displayed on webpage, then information accessibility is improved, but DOI readability deteriorates when obscured by other elements
Solution Approach 1:
The patent performs preliminary detection to identify potential overlaps between the DOI and other information elements before they can obscure each other. The system continuously monitors the display positions and proactively adjusts or hides overlapping elements before the DOI becomes obscured, ensuring continuous readability.
Solution Approach 2:
The patent implements a feedback mechanism that continuously monitors the display position of the DOI and other information elements. When overlap is detected, the system provides feedback by automatically adjusting the display (hiding or moving overlapping elements) to restore DOI visibility, creating a closed-loop system that maintains DOI readability.
Data Source
AI summary
A terminal device for securely displaying information is provided. The terminal device includes a monitoring module configured to monitor a display position of a Digital Object Unique Identifier (DOI) and a display position of other information on a page displayed on the terminal device, and a processing module configured to hide at least a portion of the other information that overlaps the DOI to expose the DOI when it is detected that the display position of the other information overlaps the display position of the DOI.
