Mobile Terminal Progress Bar Multi-Touch Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals lack efficient methods for users to control content playback using touch inputs on a progress bar, limiting user flexibility in managing and editing content.
Innovation Solution
A mobile terminal and method that utilize multi-touch inputs on a progress bar to allow users to select and manipulate playback portions, enabling easier control of content playback, frame manipulation, and editing by allowing touch inputs for selecting, dragging, and modifying playback sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional single-touch or basic touch operations are used on the progress bar, then the operation method is simple, but the user cannot efficiently control or edit content playback or manipulate frames
Solution Approach 1:
The progress bar is divided into multiple selectable portions that correspond to different frames or time segments of the content. Users can perform multi-touch operations on specific segments to control playback or edit frames independently, allowing precise manipulation of content portions without affecting the entire playback sequence.
Solution Approach 2:
The patent introduces multi-dimensional touch inputs (multi-touch, multi-gesture) on the one-dimensional progress bar. By allowing multiple touch points and gesture types simultaneously, the system transforms simple linear progress bar interaction into a multi-dimensional control interface that supports both playback control and frame manipulation.
2Adaptability or versatility
If multi-touch inputs are added to the progress bar to enable frame manipulation, then the versatility of control is improved, but the complexity of the operation interface increases
Solution Approach 1:
The progress bar is designed as a universal control interface that handles multiple functions through a unified multi-touch mechanism. The same progress bar structure and touch input method support both content playback control and frame manipulation, eliminating the need for separate controls and reducing overall interface complexity despite the enhanced functionality.
Solution Approach 2:
The system automatically interprets multi-touch gestures on the progress bar and executes the appropriate control or editing operation without requiring users to navigate through complex menus or modes. The interface self-adapts to the user's intent based on the touch pattern, reducing the perceived complexity for the user.
3Ease of operation
If the progress bar is made interactive with multi-touch support, then user accessibility to specific content portions is enhanced, but the device requires more complex processing to handle multiple touch inputs
Solution Approach 1:
The patent extracts and processes only the essential touch parameters (touch points, gestures, and their correspondence to progress bar portions) needed for playback control and frame manipulation. By focusing on extracting only the relevant information from multi-touch inputs rather than processing all possible touch data, the system maintains simplicity in the processing logic while providing comprehensive user control.

AI summary
A mobile terminal is disclosed. The mobile terminal displays a progress bar for controlling the playback of content, selects two points on the progress bar, and upon receipt of a predetermined operation on the two points, controls the playback of the content, which has a playback portion between the two points. Accordingly, time-based content can be managed more efficiently through the progress bar.
