Progress Bar Magnification for Precise Mobile Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing progress adjustment methods on mobile devices suffer from low accuracy due to the small screen size, resulting in large progress spans with minor user input, and offer limited flexibility in adjustment manner.
Innovation Solution
A method that displays a progress bar with a unit progress corresponding to the device's side length, allowing for a second sliding operation to generate a sub-progress bar with a smaller unit progress, enabling more precise adjustments by geometrically stretching the progress unit, and allowing both rough and fine adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a progress bar is displayed on a small mobile device screen, then the device can display progress information, but the progress span per unit length becomes large resulting in low adjustment accuracy
Solution Approach 1:
The progress bar is segmented into multiple levels: a first progress bar for rough adjustment and a second progress bar (magnified version) for fine adjustment. When the user slides on the first progress bar, a magnified portion is displayed as the second progress bar, allowing precise positioning. This segmentation resolves the contradiction by dividing the adjustment task into coarse and fine stages, achieving high accuracy despite limited screen area.
Solution Approach 2:
The patent transitions from a one-dimensional progress bar to a two-dimensional interaction model by displaying a magnified portion of the progress bar in a different spatial dimension. The second progress bar is presented as a separate visual layer that expands vertically from the first progress bar, creating a multi-dimensional adjustment interface that overcomes the linear space limitation of the original screen area.
2Adaptability or versatility
If a single progress bar is used for progress adjustment, then the interface is simple, but the adjustment manner is limited and lacks flexibility
Solution Approach 1:
The interface dynamically transforms from a single static progress bar to a multi-level interactive structure. The first progress bar can transition to display the second progress bar based on user interaction (sliding operation), creating a dynamic adjustment system that adapts to the user's precision needs. This dynamic behavior provides flexibility without permanently increasing interface complexity.
Solution Approach 2:
The first progress bar serves multiple functions: it acts as the primary progress indicator, enables rough adjustment, and serves as the base for generating the magnified second progress bar. This multi-functionality allows a single interface element to provide both coarse and fine adjustment capabilities, enhancing versatility while maintaining interface simplicity.
