Icon Boundary Detection for Intuitive Page Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for moving icons between pages on large screens require long-distance dragging operations, increasing user burden and risk of erroneous page switching due to inadequate finger detection at the screen edges.
Innovation Solution
A user interface apparatus that determines whether an icon's end portion is in contact with the display frame, allowing intuitive page switching without the need for a UI operation region in the icon moving direction, and adjusts thresholds based on icon size to prevent erroneous recognition of finger release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional drag & drop operation is used on a large-size screen, then the icon can be moved to an arbitrary page, but the operation distance becomes long and the operational burden increases
Solution Approach 1:
The patent introduces a new dimension for page switching by detecting contact with the display frame boundary rather than requiring movement across the entire screen. This changes the operation from a horizontal/vertical traversal to a boundary-based contact detection, effectively reducing the operational burden while maintaining full functionality.
Solution Approach 2:
The system prepares multiple pages in advance and pre-positions them for switching when the icon approaches the display frame. This allows the page switch to occur seamlessly as the icon nears the boundary, eliminating the need for long-distance dragging and reducing operational steps.
2Reliability
If the finger is released at the right or left end portion of the screen during drag operation, then the system may erroneously recognize that the finger has been released from the icon, but this causes the icon to return to the original position and complicates the operation
Solution Approach 1:
The display frame serves as an intermediary indicator that mediates between the user's drag gesture and the system's page switching logic. When the icon contacts the display frame, this intermediate signal triggers the page switch, eliminating the ambiguity of finger release detection at screen edges and preventing erroneous icon position recovery.
Solution Approach 2:
The patent employs visual feedback through color changes or display frame highlighting to indicate when an icon is in a state ready for page switching. This visual cue helps users understand the system's recognition state, preventing erroneous operations and simplifying the overall interaction.
3Measurement precision
If a UI operation region is required for icon movement, then the system can detect operations accurately, but this reduces the available display area and complicates the interface design
Solution Approach 1:
The patent extracts the operation detection function from a dedicated UI operation region and relocates it to the display frame boundary itself. This allows the entire screen to serve as the display area while maintaining accurate operation detection through frame contact detection, effectively eliminating the need for separate operation zones.

AI summary
The present invention intends to improve the operability when a user performs a drag & drop operation to shift an icon from the present page to another page. A user interface apparatus detects whether an end portion of an icon has been brought into contact with a display frame of the page, irrespective of the position of a finger or a pen that operates the icon. If the contact state continues for a predetermined time, the user interface apparatus causes the page to transit. Therefore, smoothly and intuitively shifting the icon to the next page is feasible.
