Gesture-Based Screen Capture with Velocity-Angle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen capturing methods require users to manually select options or define hotkeys, making them inconvenient due to varying switching modes and key positions across different screen capturing software.
Innovation Solution
A method that enables screen capturing by inputting a gesture involving a continuous track with specific velocity and angle conditions, automatically switching the capturing mode to use a preset capturing box without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection or hotkey definition is used to enable screen capturing, then the capturing function can be activated, but the operation becomes inconvenient due to varying switching modes and key positions across different software
Solution Approach 1:
The system automatically detects the current software context and enables the appropriate capturing mode without requiring manual user selection. The capturing function serves itself by autonomously adapting to the application environment, eliminating the need for users to learn and remember different hotkeys or switching modes for different software.
Solution Approach 2:
The system dynamically changes the activation parameters (gesture recognition, context detection) based on the current software environment. By adjusting the detection parameters according to the active application, the system provides consistent ease of operation across different software without requiring users to adapt to varying configurations.
2Adaptability or versatility
If users need to learn and remember multiple hotkeys and switching modes for different screen capturing software, then comprehensive capturing functionality is achieved, but user burden increases
Solution Approach 1:
The system implements a universal gesture-based activation mechanism that works across multiple screen capturing software applications. Instead of requiring separate hotkeys for each software, a single unified gesture (clicking and dragging the mouse button) serves all capturing functions, making the system universally applicable while reducing user burden.
Solution Approach 2:
The system automatically identifies the active screen capturing software and activates the appropriate capturing mode through gesture detection, eliminating the need for users to manually select modes or remember software-specific hotkeys. The system serves itself by autonomously adapting to the software context.
3Ease of operation
If a gesture-based automatic switching system is implemented, then ease of operation is improved, but the system complexity increases
Solution Approach 1:
The system introduces a gesture recognition intermediary layer between user input and capturing mode activation. This intermediary translates simple mouse click-and-drag gestures into context-aware mode switching commands, shielding users from system complexity while enabling automatic adaptation to different software environments.
Solution Approach 2:
The system continuously monitors mouse position, click state, and software context to dynamically determine the appropriate capturing mode. By implementing real-time feedback loops that adjust behavior based on current conditions, the system achieves intelligent automatic switching without requiring complex pre-programmed sequences.

AI summary
A screen capturing method and an electronic device using the same are provided. The screen capturing method includes that a continuous track is inputted. The continuous track includes a first stroke and a second stroke, and a first recording point is captured at a first moment of the first stroke, a second recording point is captured at a second moment of the second stroke. The first recording point includes a first velocity, and the second recording point includes a second velocity. The first velocity and the second velocity form an angle. A capturing box of a preset shape is enabled when the strokes meet the determining condition. An image is captured via the capturing box.
