Touch Screen Region Management for Multi-Application Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with limited display size and user interface face challenges in executing and managing multiple applications simultaneously, requiring repetitive execution and closing processes, which is inconvenient for users.
Innovation Solution
A method for a display device with a touch screen that allows multiple application execution windows to be displayed and controlled by setting regions on the screen and using a button to manage these regions, enabling easy execution and control of multiple applications without closing previous ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile device displays only one application at a time on the entire display area, then the application execution screen is clear and full-screen, but the user must repeatedly close and open applications to switch between them, reducing convenience and efficiency
Solution Approach 1:
The display screen is divided into multiple regions, with each region capable of displaying a different application execution window. This segmentation allows multiple applications to be visible and accessible simultaneously, eliminating the need to close applications to switch between them.
Solution Approach 2:
Instead of switching applications through time (closing one to open another), the system adds a spatial dimension by displaying multiple application windows concurrently in different screen regions, enabling parallel access to multiple applications.
2Adaptability or versatility
If the display screen is divided into multiple regions to show multiple applications simultaneously, then application switching convenience is improved, but the control complexity of multiple application windows increases
Solution Approach 1:
A control window is introduced as an intermediary element that mediates between the user and multiple application windows. The control window displays thumbnails of all application windows and provides unified control functions, simplifying the management of multiple applications.
Solution Approach 2:
The control window serves multiple functions: displaying thumbnails of all application windows, enabling selection of active windows, and providing unified control operations. This multi-functional design consolidates control mechanisms and reduces overall system complexity.
3Productivity
If multiple application execution windows are displayed on the screen, then the user can access multiple applications simultaneously, but the display area available for each application is reduced
Solution Approach 1:
The regions displaying application windows are designed to be dynamically resizable and repositionable. Users can adjust the size and position of each application window according to their needs, allowing flexible optimization of display area allocation while maintaining multi-application capability.
