Touchscreen Screenshot Gesture Control via Press-and-Slide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screenshot methods on mobile terminals are cumbersome and complex, requiring users to adapt to different operation modes for page, area, and long screenshots, leading to poor user experience.
Innovation Solution
A method that detects a pressing operation on a touch screen, determines the screenshot page based on a preset duration, and captures a screenshot image based on the positional relationship between the end point of a sliding operation and the page, allowing for seamless transition between page, area, and long screenshot modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation modes are provided for different screenshot types (page, area, long screenshot), then the screenshot functionality becomes versatile and adaptable, but the operation complexity increases and user experience deteriorates
Solution Approach 1:
The patent implements a universal screenshot method where a single pressing-and-sliding gesture can achieve multiple screenshot types (page screenshot, area screenshot, long screenshot) without requiring users to learn different operation modes. The system determines the screenshot type automatically based on the sliding distance and duration, making one operation serve multiple functions.
Solution Approach 2:
The system performs self-service by automatically determining the screenshot type and capturing area based on the user's sliding gesture characteristics. The processor analyzes the sliding distance, duration, and starting position to automatically select the appropriate screenshot mode, eliminating the need for users to manually configure or select different operation modes.
2Adaptability or versatility
If users need to adapt to different operation modes for different screenshot types, then various screenshot requirements can be met, but the user experience becomes poor and tedious
Solution Approach 1:
The patent creates a universal interaction paradigm where one pressing-and-sliding gesture covers all screenshot types. The system adapts to different screenshot requirements automatically based on gesture parameters, so users don't need to learn multiple operation modes but still access all screenshot functionality.
Solution Approach 2:
The system uses parameter changes in the sliding gesture (distance, duration, speed) to differentiate between screenshot types. By analyzing these parameters, the system automatically selects the appropriate screenshot mode, making the interface adaptive to user needs without requiring explicit user input for each type.
3Ease of operation
If a simple pressing operation is used to trigger screenshot, then the operation becomes simple and intuitive, but the system needs to accurately determine screenshot parameters based on duration and sliding position
Solution Approach 1:
The system performs preliminary detection of the pressing operation duration and sliding gesture parameters before executing the screenshot. By pre-measuring the duration, distance, and trajectory of the sliding gesture, the system prepares the necessary parameters for accurate screenshot capture, ensuring simple user input leads to precise output.
Solution Approach 2:
The system implements feedback by continuously monitoring the sliding gesture parameters (position, speed, duration) and using this real-time information to determine the screenshot type and area. The processor provides feedback control by adjusting the screenshot parameters based on the detected gesture characteristics, ensuring accurate capture despite simple user input.

AI summary
It is disclosed a screenshot capturing method, a screenshot device, an electronic device and a computerreadable medium, relating to the field of mobile terminals. The method includes: obtaining a duration of a pressing operation when the pressing operation acting on the touch screen is detected; determining a specified page currently displayed on the touch screen, when the duration reaching a preset duration is determined; obtaining a sliding operation acting on the touch screen, wherein the sliding operation and the pressing operation are successive operations; obtaining a positional relationship between an end point of the sliding operation and the specified page, when the sliding operation ends; determining a screenshot image according to the positional relationship and the sliding operation, and capturing the screenshot image. Therefore, the screenshot image can be determined by pressing operation and sliding operation and the screenshot operation can be realized. The screenshot operation is simple and not complicated, and the user experience can be improved.
