Stylus Remote Screenshot for Large Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen terminal devices pose challenges in taking screenshots, as users struggle to capture specific areas of interest remotely, leading to poor screenshot quality and user experience.
Innovation Solution
A method and device that utilize a stylus to acquire an initial and target position on the screen, allowing for remote capture of any screen area, thereby simplifying the screenshot process and ensuring key content is highlighted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire screen is captured for screenshot, then the screenshot covers all content, but the key content cannot be highlighted and the screenshot effect is poor
Solution Approach 1:
The patent introduces a stylus as an intermediary tool to bridge the gap between the user and the large-screen device. The stylus transmits control signals wirelessly to the terminal device, enabling remote selection of screenshot areas without requiring direct contact with the screen, thus solving the contradiction between precision and ease of operation
Solution Approach 2:
The patent creates a virtual representation of the screen on a smaller display device through the stylus connection. Users can view and select screenshot areas on the smaller device, which then translates to the corresponding area on the large screen, effectively copying the control interface to a more manageable scale
2Illumination intensity
If the large-screen terminal device is used for better display experience, then the display quality improves, but the device is far away from the user making screenshot operation difficult
Solution Approach 1:
The stylus serves as a remote intermediary control device that wirelessly communicates with the terminal device. It transmits touch coordinates and control signals from the user's hand to the distant screen, enabling operation of the large-screen device without physical proximity
Solution Approach 2:
The patent replaces the mechanical requirement of direct finger contact with the screen with wireless electromagnetic communication. The stylus uses wireless transmission to send control signals to the terminal device, eliminating the need for physical proximity while maintaining precise control

AI summary
A method for taking a screenshot includes: acquiring an initial position indicated by a stylus on a screen of a terminal device at a first moment, in response to an instruction of enabling a remote screenshot function; acquiring a target position indicated by the stylus on the screen at at least one second moment after the first moment; and remotely capturing screen content corresponding to the initial position and the target position at the at least one second moment in response to a screenshot instruction, to acquire the screenshot.
