Edge Content Selection via Cursor-Triggered Webpage Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting edge content on mobile terminals due to incomplete sensing at the edge of capacitive touch-screens, making it impractical to choose content that extends beyond the screen, especially when using inferior devices.
Innovation Solution
A method and device that detect the movement of cursors towards the screen edge, triggering the content webpage to move in the opposite direction when the cursor reaches a predetermined distance from the edge, bringing the edge content closer to the center, allowing easier selection of edge content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cursor is dragged to the edge of the screen to select edge content, then the content can be selected, but the touch-screen sensing units at the edge are incomplete causing selection difficulty or impracticality
Solution Approach 1:
Instead of moving the cursor to the edge of the screen to select edge content, the patent inverts the approach by moving the content webpage in the opposite direction toward the center of the screen. This allows the cursor to remain within the reliable sensing area while still enabling selection of edge content through content movement.
Solution Approach 2:
The content webpage acts as an intermediary between the cursor and the edge content. By moving the content webpage in response to cursor movement toward the edge, the system enables indirect selection of edge content without requiring the cursor to reach the unreliable edge sensing area.
2Area of stationary object
If the webpage content width is wider than the mobile terminal screen, then more content can be displayed, but the edge content extends beyond the screen and cannot be selected
Solution Approach 1:
The system dynamically adjusts the position of the content webpage based on cursor movement. When the cursor approaches the screen edge, the content webpage automatically moves in the opposite direction, dynamically creating accessibility to edge content without requiring manual scrolling or screen expansion.
Solution Approach 2:
Rather than expanding the display area beyond the screen or moving the cursor to the edge, the patent inverts the solution by moving the content webpage toward the center in response to cursor edge-approach, enabling edge content selection within the existing screen boundaries.
3Measurement precision
If a magnifier function is used to display edge content magnified, then edge content becomes visible, but the solution does not address the incomplete sensing units at the touch-screen edge
Solution Approach 1:
The patent extracts the magnifier function from the solution and replaces it with a simpler content movement mechanism. Instead of magnifying edge content which requires complex display handling, the system simply moves the content webpage to bring edge content within the reliable sensing area, eliminating the need for magnification while maintaining selection capability.

AI summary
Method, device, and storage medium for selecting edge content of a webpage. The method includes, upon detecting that a user performs the operation of dragging the cursor part of the two cursors used to define a selection area toward a screen edge of a touch-screen of a mobile terminal, moving the cursor toward the screen edge of the touch-screen; determining whether the distance between the screen edge and the cursor part after the movement of the cursor is within a first predetermined distance; and, when within the first predetermined distance, triggering the content webpage to move in an opposite direction.
