Touchscreen Playback Control via Gesture Hybrid Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in precisely controlling the playback progress of multimedia files on mobile terminals, as existing methods often result in inaccurate adjustments due to imprecise dragging of progress bars.
Innovation Solution
A method and apparatus that integrate step speed and playback progress regulation, allowing users to adjust the step speed and playback progress through hybrid operations on a touchscreen, using a combination of slide and touch instructions to accurately control playback speed and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users drag the progress bar to adjust playback progress, then playback progress can be adjusted, but the precision of playback progress adjustment deteriorates due to imprecise dragging
Solution Approach 1:
The patent replaces the traditional mechanical dragging interaction with a gesture-based interaction system. By detecting finger gestures (swiping, pinching, palmoting) on the touchscreen, the system translates intuitive hand movements into precise playback control commands, eliminating the need for direct progress bar dragging while achieving higher precision
Solution Approach 2:
The patent changes the control parameters from direct pixel-based dragging to gesture-based control. By mapping gesture characteristics (direction, distance, speed) to playback parameters (progress adjustment amount, speed), the system achieves more precise and controllable playback progress adjustment
2Device complexity
If traditional progress bar dragging is used, then playback control is simple, but playback precision deteriorates causing misoperations
Solution Approach 1:
The patent makes the gesture recognition system multi-functional by enabling it to handle various playback control scenarios through a unified gesture interface. The same gesture recognition mechanism can control playback progress, adjust playback speed, and navigate different media content, replacing multiple separate control interfaces with one versatile system
Solution Approach 2:
The system incorporates real-time feedback by detecting gesture characteristics (direction, distance, speed) and immediately translating them into corresponding playback actions. This feedback loop ensures accurate control by continuously monitoring user gestures and adjusting playback parameters accordingly, preventing misoperations
