Knuckle Touch Screen Splitting on Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen splitting operations on terminal devices are complex and inconvenient, requiring coordination between screen splitting keys and touch gestures, with fixed window sizes and quantities, which hinders flexible presentation of multiple application programs on a single display UI.
Innovation Solution
A quick screen splitting method is implemented by detecting a knuckle touch gesture on a touch-sensitive surface, allowing for simple and flexible splitting of the display UI into multiple areas based on preset conditions, such as capacitance, acceleration, and gesture tracking, enabling users to adjust boundaries and sizes dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screen splitting key or virtual switch coordinated with touch gesture is used for screen splitting, then the screen splitting function can be activated, but the operation steps become complex and user experience deteriorates
Solution Approach 1:
The patent extracts the screen splitting function from complex coordinated operations (key + gesture) and implements it through a single touch gesture operation. The screen splitting key or virtual switch is removed from the operation sequence, leaving only the touch gesture to trigger screen splitting, thereby simplifying the operation steps while maintaining the screen splitting capability
Solution Approach 2:
The touch-sensitive surface is given multiple functions: it serves both as the display interface and as the trigger mechanism for screen splitting. By making the touch gesture universal (able to both trigger splitting and define boundary), the system reduces the number of separate components needed and simplifies the overall operation
2Adaptability or versatility
If fixed window sizes and quantities are used in screen splitting, then the screen layout is stable, but the flexibility to present multiple application programs deteriorates
Solution Approach 1:
The patent transforms the static, fixed window sizes and quantities into dynamic, user-configurable parameters. The touch gesture allows users to dynamically adjust the boundary position, which in turn dynamically changes the size and quantity of display areas. This dynamic adjustment capability provides adaptability for different application scenarios while maintaining operational simplicity
Solution Approach 2:
The display UI is segmented into multiple display areas through the touch gesture boundary. This segmentation is flexible and can be adjusted by the user to create different configurations (e.g., two equal areas, one large and one small, three areas, etc.), providing adaptability for presenting multiple application programs in various layouts
3Reliability
If conventional touch gestures are used for screen splitting, then the gesture recognition is simple, but the likelihood of misoperation increases
Solution Approach 1:
The patent applies local quality by using specific characteristics of the knuckle touch (capacitance distribution pattern, pressure distribution) to distinguish it from other touch gestures. Instead of relying on generic touch parameters, the system analyzes the local quality of the touch input to accurately identify knuckle touches and reduce misoperation

AI summary
Embodiments of the present invention disclose a quick screen splitting method, apparatus, and electronic device, a display user interface (UI), and a storage medium, and relate to the electronic field. The method includes: detecting, by a portable electronic device, a knuckle touch gesture acting on a touch-sensitive surface of the portable electronic device, and splitting, by the portable electronic device, a UI into at least two display areas in response to the knuckle touch gesture. The knuckle touch gesture includes a knuckle touch action that occurs when a touch-sensitive surface grid capacitance generated by the knuckle touch action acting on the touch-sensitive surface is within a first preset capacitance range, a quantity of non-zero capacitance grids is less than a preset value, and a Z-axis direction acceleration signal is within the first preset acceleration range.
