Touch Screen Web Content Enlargement via Layered Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional zoom-in/out methods on mobile communication terminals with small screens make it difficult for users to select specific web content, such as hyperlinks, due to the limited screen size and increased number of operations required, leading to inconvenience in web navigation.
Innovation Solution
A method and apparatus for efficiently displaying web content on a mobile communication terminal with a touch screen, involving determining touch inputs to select and enlarge specific areas, applying a predefined ratio for overlapping the selected area on the entire screen, and using a mobile browser engine to control the enlargement scheme, thereby improving rendering performance and providing a dynamic view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a zoom-in/out function is added to enlarge/reduce a specific area, then the display area of specific content is improved, but the ease of operation deteriorates due to increased number of operations required
Solution Approach 1:
The patent divides the display into multiple layers: a background layer showing the entire web content screen and a foreground layer showing the enlarged specific area. This segmentation allows users to view both the overview and detailed content simultaneously without needing to zoom in/out repeatedly, reducing the number of operations required.
Solution Approach 2:
The patent introduces a new dimension by overlaying the enlarged area on top of the background screen rather than replacing it. This creates a multi-layered display structure where the foreground layer (enlarged area) and background layer (entire screen) coexist, allowing users to navigate and select content more efficiently.
2Area of moving object
If the entire screen displays only an enlarged area, then the display area of specific content is improved, but the loss of information increases as users cannot view the entire screen context
Solution Approach 1:
The display is segmented into two simultaneous views: the background layer preserves the entire screen context showing all web content, while the foreground layer provides the enlarged specific area. This segmentation ensures that neither the detailed view nor the overview is lost.
Solution Approach 2:
The patent merges the entire screen display and the enlarged area display into a single multi-layered interface. The background layer shows the complete web content while the foreground layer overlays the enlarged portion, combining both views in one display rather than requiring separate screens.
3Area of moving object
If conventional zoom-in/out method is used, then the display area of specific content is improved, but the device complexity increases due to multiple zoom operations required
Solution Approach 1:
The patent segments the display into layered structures (background and foreground layers) rather than using sequential zoom operations. This eliminates the need for multiple zoom-in/out steps and reduces the complexity of navigation operations.
Solution Approach 2:
The patent prepares both the entire screen view and the enlarged specific area view in advance by creating layered display structures before user interaction. This preliminary preparation eliminates the need for users to perform multiple zoom operations to achieve the desired view.

AI summary
A method for displaying web content on a mobile communication terminal is provided. When a touch input is received from a user for web content displayed on the mobile communication terminal having a touch screen, a process for selecting an area to be enlarged at a position where the touch input is generated and overlapping, enlarging, and displaying the selected area on the entire screen is performed. When the selected area is enlarged, rendering performance can be improved and a dynamic view can be provided to the user.
