Touch Screen Gesture Recognition for Region-Specific Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen capture methods on terminal devices are cumbersome, requiring hardware buttons or stylus input for capturing specific screen regions, leading to complex operations and poor user experience.
Innovation Solution
Implementing a screen capture method that recognizes same-direction parallel swiping of two fingers on the screen to capture images from specific regions, eliminating the need for external tools and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hardware buttons are used for screen capture, then the capture function is implemented, but the operation is complex and lacks content pertinence
Solution Approach 1:
The patent replaces the mechanical hardware button system with a software-based gesture recognition system. The touch screen detects finger movements and translates them into screen capture commands, eliminating the need for physical buttons while maintaining capture functionality and improving ease of operation.
Solution Approach 2:
The touch screen serves multiple functions: it displays content, detects user gestures, and triggers screen capture operations. This multi-functionality reduces device complexity by consolidating what would otherwise require separate hardware components into a single integrated system.
2Ease of operation
If stylus swipe recognition is used for region capture, then specific region capture is enabled, but the operation remains tedious and requires external tools
Solution Approach 1:
The system uses the user's own fingers as the input tool, eliminating the need for external styluses or tools. The touch screen naturally detects finger swipes and translates them into capture commands, making the system self-sufficient and more accessible to users without requiring additional hardware.
Solution Approach 2:
The patent changes the detection parameters from stylus-based to finger-based touch detection. By adjusting the sensitivity and recognition parameters to accommodate finger movements, the system achieves region capture functionality while improving ease of operation and removing the need for external tools.
3Ease of operation
If full screen capture is implemented, then the capture function works, but it lacks content pertinence and requires further processing
Solution Approach 1:
The patent implements local quality by capturing only the specific region of interest rather than the entire screen. The gesture recognition system identifies the user's intended region through finger swipes and captures only that area, eliminating unnecessary post-processing and saving time while maintaining operational ease.

AI summary
The present invention discloses a screen capture method, an apparatus, and a terminal device, where a part of an image in a screen display region can be captured by means of gesture recognition. The method includes: when it is detected that two fingers swipe parallel in a same direction on a screen, acquiring a screen capture region according to the same-direction parallel swiping; and acquiring, according to the screen capture region, an image displayed in the screen capture region. According to the screen capture method, the apparatus and the terminal device in the embodiments of the present invention, a screen capture operation is performed by recognizing same-direction parallel swiping of two fingers on a screen, so that a user can capture an image displayed in a part of a region of the screen according to an individual requirement, and the screen capture method is applicable to various touch-operation terminal devices without the help of an external tool, thereby simplifying the operation and improving user experience.
