Free Window Adjustment via Multi-Touch Angle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals with Android operating systems prior to version 7.0 can only display one application interface at a time in the foreground, limiting the ability to adjust multiple application windows simultaneously, such as in split-screen mode, where zooming in on one application causes the other to become smaller and unadjustable.
Innovation Solution
Implementing a method for window adjustment that monitors touch information on a display interface in free window mode, determining the angle between sliding directions of multiple contacts to perform zooming or moving operations on free windows, allowing users to adjust the size and position of application interfaces independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If split-screen mode is implemented to display multiple applications simultaneously, then the ability to display multiple application interfaces is improved, but the ability to independently adjust window size and position is worsened because zooming in on one application causes the other to become smaller and unadjustable
Solution Approach 1:
The display interface is segmented into multiple independent free windows, each capable of displaying a different application interface. Each window can be independently adjusted in size and position through touch gestures, allowing users to resize or move one window without affecting the others. This segmentation resolves the contradiction by enabling both multi-application display and independent window control.
Solution Approach 2:
The window system transitions from a fixed, rigid layout to a dynamic, flexible layout where window sizes and positions can be freely adjusted. The system dynamically responds to user gestures (single-finger and multi-finger operations) to resize, move, or maximize windows in real-time, enabling independent adjustment of each application interface while maintaining multi-application display.
2Stability of the object's composition
If fixed window sizes and positions are used in multi-window mode, then the system stability is improved, but the flexibility and user-friendliness of window adjustment are worsened
Solution Approach 1:
The system implements dynamic window adjustment where window sizes and positions can be freely modified through touch gestures. Users can perform single-finger or multi-finger sliding operations to resize, move, or maximize windows, transforming the previously fixed window system into a flexible, adaptive one that maintains stability through controlled user interactions.
Solution Approach 2:
The system allows dynamic changes to window parameters (size and position) through gesture-based controls. By detecting the number of fingers and sliding directions, the system adjusts window parameters in real-time, enabling users to optimize the display layout for different applications while maintaining system stability through structured interaction protocols.
3Device complexity
If only one application interface is displayed at a time, then the simplicity of the display system is improved, but the productivity and efficiency of multi-tasking are worsened
Solution Approach 1:
The display interface is divided into multiple independent free windows, each capable of displaying a different application interface simultaneously. This segmentation enables multi-tasking by allowing users to view and interact with multiple applications at once, significantly improving productivity while maintaining relatively simple system architecture through the use of standard touch gesture controls.

AI summary
A window adjustment method is provided and includes operations of: when an application program in a mobile terminal being displayed in the form of a free window, monitoring touch-control information on a display interface of the mobile terminal; if the monitored touch-control information is sliding information of two touch points, determining a free window corresponding to the touch-control information, and determining an angle between the sliding directions of the two touch points; and based on the angle between the sliding directions of the two touch points, zooming or moving the free window corresponding to the touch-control information.
