Split View Application Switching via Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals face difficulties in seamlessly switching between applications while maintaining a split view, requiring complex key or touch interactions and inefficient window management.
Innovation Solution
A method and apparatus that allow users to switch applications by detecting a long tap with two fingers, reducing application sizes, displaying candidate applications, and moving them based on drag direction, enabling seamless switching within a split view without losing the split view layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional split view switching methods are used, then application switching is achieved, but the split view layout is lost and complex escape operations are required
Solution Approach 1:
The system prepares candidate application thumbnails in advance within the split view interface. When the user performs a swipe gesture, the selected candidate application is immediately activated without requiring escape to full-screen mode or additional navigation steps, thus resolving the contradiction between ease of operation and time loss.
Solution Approach 2:
The patent introduces thumbnail previews of candidate applications as an intermediary element within the split view. These thumbnails serve as a mediation mechanism that allows users to switch applications directly from the split view without fully exiting it, eliminating the need for complex escape operations and reducing switching time.
2Adaptability or versatility
If fixed 1/2 split view is used, then two applications are displayed simultaneously, but switching to other applications requires escaping the split view
Solution Approach 1:
The system transitions from a static fixed 1/2 split view to a dynamic interface where candidate application thumbnails can be swiped through and selected. This dynamic interaction allows application switching while maintaining the split view structure, improving ease of operation without sacrificing adaptability.
Solution Approach 2:
The patent adds a temporal dimension to the split view by introducing swipeable candidate thumbnails that appear in sequence. This dimensional enhancement allows users to navigate through multiple application options within the existing split view framework, eliminating the need to escape for switching while maintaining versatile application display.
3Adaptability or versatility
If PC-like Free Style window is used, then multiple applications are accumulated, but switching requires window removal and complex operations
Solution Approach 1:
The system extracts the essential function of application switching from complex window management operations. By presenting candidate applications as selectable thumbnails within the split view, it separates the switching function from the need to manipulate full windows, thereby reducing device complexity while maintaining multi-application adaptability.
Solution Approach 2:
The patent creates simplified copies (thumbnails) of candidate applications that can be selected without manipulating the full application windows. These thumbnail copies enable straightforward switching operations while the actual application windows remain managed in the background, reducing the complexity of visible window management operations.
4Productivity
If conventional application switching is performed, then application switching is achieved, but the split view state cannot be maintained
Solution Approach 1:
Candidate application thumbnails are prepared in advance within the split view interface. When selected via swipe gesture, the switching action is executed immediately while the split view layout remains intact, thereby maintaining layout stability and improving switching efficiency simultaneously.
Solution Approach 2:
The candidate thumbnail serves as an intermediary that enables application switching without disrupting the split view composition. By interacting with the thumbnail rather than directly switching applications, the system maintains the visual stability of the split view while achieving efficient application switching.

AI summary
A method of displaying a view in a portable terminal includes: displaying a plurality of applications as a split view corresponding to a split display region of a display unit; reducing and displaying an application of the split view and switchable candidate applications in a switch mode; displaying an application selected from the candidate applications and changing an application displayed on the split view in a previous state to the candidate application; and enlarging and displaying the split view when the switch mode is terminated.
