Cross-Device App Window Transfer via Screenshot and Icon Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the field of intelligent terminals, gesture operations for controlling electronic devices often require high precision, leading to misoperations due to narrow operation areas, which complicates the management and execution of multiple functions with a single gesture.
Innovation Solution
A human-computer interaction method that allows for cross-screen display of applications by sending a screenshot and identification information from one electronic device to another, enabling users to perform gesture operations on icons or screenshots to move application windows between devices, reducing the need for precise gestures and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functions are completed by using one gesture operation at different locations, then the number of gesture operation types is reduced, but the operation area becomes narrow and precision requirement increases
Solution Approach 1:
The patent segments the gesture operation process into two independent stages: first, a coarse selection stage where the user performs a gesture anywhere on the screen to select an application; second, a fine control stage where the user performs the actual function operation. This segmentation separates the selection precision requirement from the operation precision requirement, allowing the first stage to have a large operation area without requiring high precision.
Solution Approach 2:
The patent introduces an intermediary interface (such as a popup menu or selection panel) that appears after the first gesture. This intermediary serves as a mediator between the user's initial gesture and the final function execution, allowing the user to confirm or adjust their selection before the actual operation is performed, thereby reducing the precision requirement of the initial gesture.
2Measurement precision
If a gesture operation is limited to a narrow operation area to implement a function, then function control precision is improved, but misoperation is easily generated when gesture location deviates
Solution Approach 1:
The patent implements a confirmation mechanism before executing the function. After the user performs the first gesture to select an application, the system presents a confirmation interface or preview showing the selected application and the function that will be executed. This allows the user to verify the selection and correct any deviations before the actual function is performed, cushioning against potential misoperations.
Solution Approach 2:
The system provides visual feedback after the first gesture by displaying the selected application icon, name, or a preview of the function to be executed. This feedback loop allows the user to confirm whether the gesture was correctly interpreted and adjust if necessary, thereby improving operation reliability without requiring extremely precise gesture input.
3Manufacturing precision
If high precision gesture operation is required, then function execution accuracy is improved, but user operation complexity increases
Solution Approach 1:
The patent divides the operation into two simple, sequential gestures: a first gesture for application selection and a second gesture for function execution. Each gesture has a clear, simple purpose and can be performed with a relatively large operation area. This segmentation reduces the complexity of individual gestures while maintaining high function execution accuracy through the two-stage process.
Solution Approach 2:
Instead of requiring a single complex high-precision gesture to both select and execute a function, the patent inverts the approach by using two simpler gestures: the first gesture has low precision requirements (large operation area) for selection, and the second gesture has high precision requirements but a smaller, more manageable operation area for execution. This inversion reduces overall operation complexity.

AI summary
In a human-computer interaction method, a second electronic device receives a first picture and identification information of at least one application that are sent by a first electronic device based on a first operation. The second electronic device displays the first picture and an icon of the at least one application. The second electronic device receives a second operation performed on a first icon, where the first icon is one icon in the icon of the at least one application. In response to the second operation, content of an application window of a first application displayed by the second electronic device is the same as that of an application window of the first application opened on a first interface.
