Touch Display Image Capture via Motion Track Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for capturing images on touch display modules in portable electronic devices are inconvenient, as they require pressing specific keys or simultaneously pressing multiple keys to capture the whole screen, lacking simplicity and user-friendliness.
Innovation Solution
An image capturing method that involves defining perpendicular axes, detecting motion tracks with angles or curves on a touch display module, calculating the lengths of these tracks projected onto the axes, and capturing a selecting range based on these lengths, allowing for a wider scope of image capture with simplified and visualized operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional key-based methods are used to capture screen images, then the capturing function can be executed, but the operation becomes inconvenient and complex for portable devices without keyboards
Solution Approach 1:
The patent replaces the mechanical keyboard-based input system with a touch-based graphical interface system. Users interact by pressing and dragging on the touchscreen to define capture areas, eliminating the need for physical keys while maintaining the screen capture functionality. This substitution directly addresses the contradiction by improving ease of operation on touch devices without adding complexity.
Solution Approach 2:
The patent introduces visual indicators and graphical overlays as intermediaries between the user and the capture function. When users press and drag on the touchscreen, visual feedback shows the selected area, making the operation intuitive and easier to understand. This intermediary layer simplifies the user experience without requiring complex underlying systems.
2Adaptability or versatility
If the whole screen image is captured using conventional methods, then complete screen content is obtained, but the operation requires pressing multiple specific keys simultaneously which is inconvenient
Solution Approach 1:
The patent divides the screen capture function into selectable regions rather than requiring capture of the entire screen. Users can press and drag to define custom rectangular areas, capturing only the portions they need. This segmentation provides flexibility in capture range while simplifying operation, as users only need to perform a simple press-and-drag gesture rather than remembering multiple key combinations.
Solution Approach 2:
The patent allows users to perform partial screen captures by selecting specific regions, rather than requiring full-screen capture. This partial action approach gives users flexibility to capture exactly what they need without the inconvenience of capturing the entire screen and then cropping it later. The operation remains simple while providing adaptability for different capture needs.
