Touch Control System for Window Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for switching between small window mode and full screen mode in electronic devices are complex, requiring users to learn specific gestures or button presses, leading to a high learning cost and poor user experience.
Innovation Solution
A method and device that determine touch point information based on touch instructions, allowing users to switch between small window mode and full screen mode by using two or three fingers in inward retraction or outward expansion motions, respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If specific gestures or button presses are used to switch between small window mode and full screen mode, then the switching function can be achieved, but the learning cost increases and user experience deteriorates
Solution Approach 1:
The system automatically detects user intent and executes mode switching without requiring users to learn or remember specific gestures or button combinations. The touch processing system self-determines when mode switching should occur based on natural touch patterns, eliminating the need for complex user learning while maintaining functional clarity
Solution Approach 2:
The patent changes the parameters of touch interaction by detecting the number of touch points and their motion states to trigger mode switching. Instead of requiring specific button presses or complex gestures, the system uses simple touch parameters (single touch, double touch, motion direction) to achieve the same functional result, significantly reducing user learning burden
2Productivity
If multiple gestures and button presses are required for mode switching, then the switching functionality is comprehensive, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent extracts the essential function of mode switching from the complex set of available gestures and button combinations, isolating the core action (touching the screen) and its minimal variations (single/double touches, motion direction). This extraction eliminates unnecessary complex operations while retaining the essential switching capability, dramatically reducing the time required for mode changes
Solution Approach 2:
Instead of requiring users to perform complex gestures to trigger mode switching, the system inverts the approach by making the touch interaction itself the trigger. The system detects natural touch behaviors (single tap, double tap, motion direction) and automatically initiates mode switching, reversing the traditional paradigm where complex user actions are required for simple functional changes

AI summary
A method for controlling an application is performed by an electronic device, and includes: determining touch point information based on a touch instruction, wherein the touch point information includes a number of touch points and motion information of each touch point, and the motion information of the touch point is configured to characterize a motion state of the touch point; and switching a display state of the application to a second display state based on a current first display state of the application and the touch point information, wherein a first one of the first display state and the second display state is a small window mode, and a second one of the first display state and the second display state is a first mode, and a display window of the first mode is larger than a display window of the small window mode.
