Portable Terminal Window Stack Management for Rapid Task Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face challenges in rapidly and conveniently switching between screens and tasks due to limited screen size, which restricts the simultaneous display of multiple application programs and hinders user convenience in multitasking environments.
Innovation Solution
A method is introduced where the portable terminal enters a window screen movement mode, allowing users to visually stack and select window screens, change transparency of stacked screens, and display the selected screen as a foreground, enabling intuitive and rapid switching between tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple application programs are displayed simultaneously on a limited screen, then user convenience for multitasking is improved, but screen complexity and difficulty of screen management increase
Solution Approach 1:
The patent applies the dimensionality change principle by transitioning from a two-dimensional screen display to a three-dimensional stacked window structure. Multiple window screens are arranged in vertical layers rather than competing for horizontal screen space, allowing users to visually perceive and manage multiple tasks through depth-based positioning. The foreground task occupies the top layer while background tasks are stacked underneath, creating a hierarchical spatial organization that simplifies multitasking management on limited screens.
Solution Approach 2:
The patent segments the screen management system into distinct hierarchical layers. Each task is assigned to a specific layer level, with the foreground task at the top and background tasks stacked below. This segmentation allows independent management of each task window while maintaining overall system organization, reducing the complexity of managing multiple simultaneous applications by dividing them into manageable hierarchical segments.
2Productivity
If traditional screen switching methods are used, then screen switching can be achieved, but switching speed and user convenience are reduced
Solution Approach 1:
The patent implements preliminary action by pre-arranging all task windows in a visible stacked configuration before switching is needed. Users can preview multiple task windows in the stack and select the desired target task in advance. When switching is initiated, the system immediately transitions to the pre-selected task, eliminating the need for sequential navigation through multiple screens or complex switching sequences, thereby accelerating the switching process.
Solution Approach 2:
The patent applies dynamics by making the window stack structure interactive and responsive to user input. The stacked windows can be dynamically manipulated through drag-and-drop operations, allowing users to reorder tasks by changing their layer positions. This dynamic rearrangement capability enables flexible task management where the most recently accessed or important tasks can be brought to the foreground, optimizing switching efficiency based on actual usage patterns.

AI summary
An operation method of a portable terminal according to an embodiment of the present invention comprises the steps of: entering a window screen movement mode in which a window screen of a foreground task is displayed uppermost and one or more window screens are stacked in multiple layers under the window screen of the foreground task; selecting a window screen from a plurality of window screens according to a user's movement command; changing the transparency of at least a part of areas of window screens stacked on the selected window screen; and displaying the selected window screen as a foreground screen and terminating the window screen movement mode when an input determining the selected window screen is received. Therefore, it is possible to switch screens and tasks more swiftly and conveniently, thereby improving user convenience.
