Flexible Screen Curvature Selection for Video Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with flexible screens rely on outdated touch inputs for object selection and media asset control, which can be cumbersome and unreliable, often resulting in incorrect selections and obscuring media assets due to the need for complex touch commands.
Innovation Solution
The system allows for object selection and media asset control based on the curvature of the flexible screen, using strain sensors to detect and analyze curvature properties, enabling actions like selection, highlighting, and media control without requiring user touch inputs, with features like bending to track moving objects and adjust playback speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch input is used to select portions of the flexible screen, then object selection can be achieved, but the operation becomes complicated and unreliable
Solution Approach 1:
The patent replaces the mechanical touch input system with a curvature-based detection system. Strain sensors mounted on the flexible screen detect curvature states to identify selected portions, eliminating the need for complex touch gestures and improving both ease of operation and reliability of selection.
Solution Approach 2:
The patent introduces curvature as an intermediary between user intent and selection. Instead of direct touch contact, the user bends the screen to create a curvature state that the strain sensors detect and translate into selection, providing a more reliable and intuitive selection mechanism.
2Ease of operation
If control buttons are displayed on the flexible screen, then media asset control can be achieved, but the media asset becomes obscured
Solution Approach 1:
The patent replaces traditional on-screen control buttons with curvature-based control. Strain sensors detect specific curvature patterns corresponding to different control commands (play, pause, rewind, fast forward), eliminating the need for visible control buttons and preserving the full media asset display area.
3Measurement precision
If the flexible screen is bent to select objects, then selection precision can be improved, but the screen deformation may cause unreliable input
Solution Approach 1:
The patent divides the flexible screen into multiple segments with individual strain sensors. This segmentation allows precise localization of curvature and selection while providing redundant detection capabilities, improving both precision and reliability of input detection.
Solution Approach 2:
The patent implements feedback by continuously monitoring curvature states through strain sensors and providing real-time selection updates. The system detects curvature, determines the selected portion, and provides visual feedback, creating a reliable closed-loop selection mechanism.

AI summary
Methods and systems are provided for selecting region of a flexible screen based on a detected curvature of the flexible screen. A mobile device detects a vertex and degree of the curvature of the flexible screen. The mobile device selects a region of the flexible screen that is centered at the vertex and whose size is proportional to the degree of curvature. The mobile device highlights the region of the flexible display to visually indicate the selected region.
