Foldable Screen Bending Input for Video Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling video play on mobile devices, such as sliding a slider on a progress bar or using fixed-time fast forward and fast backward operations, are inefficient and prone to play position jumps due to finger contact issues and lack of flexibility in speed adjustment.
Innovation Solution
A method that utilizes bending inputs to adjust the play parameters of a multimedia file, such as play progress and speed, by changing the folding angle between the screens of a foldable terminal device, eliminating the need for direct screen touch or sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user slides a slider on a progress bar to control video play, then the user can adjust play progress, but the play position jumps due to finger contact area changes on the screen
Solution Approach 1:
The patent introduces a progress bar as an intermediary element between the user's finger and the video playback system. The progress bar translates imprecise finger sliding movements into precise play position adjustments by providing visual feedback and allowing the user to release the slider at the desired position, eliminating the play position jump problem caused by direct screen contact
2Productivity
If a user uses fixed-time fast forward and fast backward operations, then the user can quickly adjust play progress, but the operations are subject to significant constraints and do not allow flexible adjustment
Solution Approach 1:
The patent implements dynamic playback speed control where the playback speed is not fixed but can be continuously adjusted by the user. The system allows users to drag the slider at different speeds and for different durations, with the playback speed adapting to the user's dragging behavior, enabling both quick adjustments and precise positioning depending on user needs
3Ease of operation
If a user slides on the screen to control video play, then the user can adjust play progress, but the video play screen might be blocked by the finger
Solution Approach 1:
The patent segments the control interface from the video display area by introducing a separate progress bar overlay. The progress bar is a distinct control element that allows users to interact with playback controls without using the main video screen area, preventing finger obstruction of the video content while maintaining ease of operation
