Segmented Progress Indicator for Precise Video Jump Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to easily select a desired position in a moving image reproduction system, such as those used for maintenance guidance in multi-function peripherals, as conventional progress bars do not facilitate precise time designation for reproduction.
Innovation Solution
A moving image reproduction apparatus with a progress display that indicates the current reproduction position and allows users to perform operations to jump to specific destinations within the image, using a candidate display to show potential jump points, enhancing user control over the reproduction process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional progress bar is used to indicate reproduction position, then the device complexity is low, but the ease of operation deteriorates as users cannot easily select desired positions
Solution Approach 1:
The progress bar is segmented into multiple display regions, each corresponding to a specific time period of the moving image. When a user touches a particular region, candidate jump destinations within that time period are displayed, enabling precise position selection without increasing overall device complexity
Solution Approach 2:
Candidate jump destinations serve as an intermediary element between the progress bar and the actual jump function. These candidates are displayed in response to touch input and provide selectable options that bridge the gap between simple progress indication and complex position selection
2Measurement precision
If detailed position selection is added to enable precise time designation, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The progress bar is divided into multiple display regions, each corresponding to a specific time period. This segmentation allows precise time designation through region-based selection while maintaining simple interaction mechanics
Solution Approach 2:
Candidate jump destinations are pre-calculated and stored based on the moving image duration and progress bar regions. When a user touches a region, the corresponding pre-identified candidates are immediately displayed, enabling precise time designation without real-time complex calculations

AI summary
A moving image reproduction apparatus for reproducing a moving image for explaining a work including a plurality of steps, includes: a reproducer that reproduces the moving image; a progress display that displays an indicator indicating a progress of reproduction of the moving image and a position on the indicator where the moving image is being currently reproduced; and a candidate display that displays a candidate image corresponding to at least one jump destination included in the moving image when a predetermined operation is performed on the indicator.
