Multi-Window Display Management on Touch Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face difficulties in presenting and managing multiple applications due to their limited display size and user interface constraints, making it inconvenient for users to run and arrange multiple windows simultaneously.
Innovation Solution
A method and display device that establish multiple window display spaces on a touch screen, allowing users to run and control applications by displaying a launcher application, receiving new application run commands, and rearranging windows through a touch-based interface, including the use of a 'ghost view' to preview window placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple applications are run simultaneously on a mobile terminal, then application functionality is improved, but display space and user interface complexity worsen due to limited screen size
Solution Approach 1:
The display screen is segmented into multiple independent window display spaces, allowing different applications to be displayed simultaneously in separate regions. The controller divides the touch screen into first, second, third, and fourth window display spaces, enabling multi-application functionality while maintaining adequate display space for each application.
Solution Approach 2:
The patent utilizes spatial arrangement in two dimensions by positioning window display spaces at different locations on the touch screen (e.g., corners, edges). This dimensional approach allows multiple applications to coexist without overlapping, effectively solving the display space constraint while maintaining versatility.
2Adaptability or versatility
If multiple window display spaces are created, then application arrangement flexibility is improved, but user interface complexity worsens
Solution Approach 1:
The system automatically manages window arrangement and application placement without requiring complex user interactions. The controller autonomously assigns applications to appropriate window display spaces and handles the complexity of multi-window management, simplifying the user interface while maintaining arrangement flexibility.
Solution Approach 2:
The touch screen and controller are designed to perform multiple functions: displaying a single application, displaying multiple applications simultaneously, and managing window arrangements. This multi-functionality reduces the need for specialized controls for each scenario, thereby reducing overall interface complexity while maintaining flexibility.
3Ease of operation
If a touch-based interface is used for window management, then ease of operation is improved, but precision in window placement worsens due to touch input limitations
Solution Approach 1:
The system pre-establishes specific window display spaces at defined locations on the touch screen before user interaction. Applications are automatically placed in these predetermined spaces, eliminating the need for precise touch-based positioning while maintaining ease of operation. The controller manages placement based on established spatial rules rather than user-determined positions.

AI summary
A method for controlling a display device that includes a touch screen is provided. The method includes establishing a plurality of window display spaces in the touch screen, wherein each of the plurality of window display spaces displays a window for running an application, displaying a launcher application in one of the plurality of window display spaces, the launcher application presenting at least one icon to run at least one application, receiving in the launcher application a new application run command to run a new application, and displaying a new window for running the new application in one of the other window display spaces than the window display space where the launcher application is displayed, in response to the new application run command.
