Stylus Closed-Region Screenshot Trigger to Avoid Miscontrol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screenshot methods using a stylus are inefficient and prone to miscontrol, especially when combined with devices that support knuckle-based screenshot operations.
Innovation Solution
A screenshot method that enters a waiting state through non-stylus operations, such as a three-finger swipe-down or knuckle tap, and detects stylus drawing of a closed figure within a preset time frame to avoid misoperations, allowing seamless integration with conventional screenshot methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screenshot button is set on the stylus to enable screenshot function, then the screenshot operation can be performed with the stylus, but miscontrol occurs and the stylus cannot be used smoothly like a common pen
Solution Approach 1:
The screenshot function is segmented into two independent parts: (1) entering screenshot waiting state through non-stylus operations (three-finger swipe-down or knuckle tap), and (2) triggering the actual screenshot through stylus detection of closed figure drawing. This segmentation eliminates the need for a screenshot button on the stylus, allowing the stylus to function smoothly like a common pen while preventing miscontrol.
Solution Approach 2:
The patent introduces an intermediary mechanism - the closed figure drawing detection - between the stylus operation and screenshot triggering. Instead of directly mapping stylus button press to screenshot, the system requires the user to draw a closed figure with the stylus nib, which serves as an intermediary action that distinguishes intentional screenshot requests from accidental stylus touches.
2Adaptability or versatility
If the terminal always stays in screenshot waiting state after non-stylus operation, then any subsequent stylus operation can trigger screenshot, but flexibility is reduced and misoperations increase
Solution Approach 1:
The system performs preliminary action by entering screenshot waiting state through specific non-stylus operations (three-finger swipe-down or knuckle tap). This preliminary action sets up a temporary state where the terminal is prepared to receive stylus input for screenshot, but only within a preset time period, thereby preventing misoperations that could occur if the waiting state persisted indefinitely.
Solution Approach 2:
The screenshot waiting state is implemented as a periodic action with a preset time limit. The terminal enters the waiting state for a specific duration after the non-stylus operation, then automatically exits. This time-bound periodic state ensures that screenshots are triggered only when intentional stylus drawing occurs within the defined time frame, balancing flexibility with misoperation prevention.

AI summary
A screenshot method, a terminal, a storage medium, and a computer program product are provided. The method includes: A terminal responds to a non-stylus operation, and enters a screenshot waiting state (S601). When the terminal establishes a connection to the stylus, the terminal detects an operation of the stylus on a touchscreen of the terminal. If an operation of drawing a closed figure with the stylus is detected, the terminal takes a screenshot of interface content in the closed region drawn with the stylus (S604). This method can avoid miscontrol in a screenshot process.
