Replay Interface Sync Between Progress Bar and Event List
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation replay systems require cumbersome and time-consuming operations to switch between a video progress bar and an operation event list to determine the corresponding event at a specific playback time point, lacking efficient synchronization.
Innovation Solution
An operation replay interface is implemented with an operation video replay area and an operation event list, where the playback progress bar is synchronized with the event list, allowing direct positioning and marking of events through trigger operations, enabling seamless navigation between the two.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only video progress bar is used for adjusting playback time point, then video playback control is simple, but operation event determination is time-consuming and cumbersome
Solution Approach 1:
The patent merges the video progress bar and operation event list into a synchronized display system where both elements are positioned and updated simultaneously based on playback time point, allowing users to determine operation events directly from the synchronized interface without switching between separate controls
Solution Approach 2:
The patent introduces a synchronized display mechanism as an intermediary between the video playback system and the operation event list, enabling automatic positioning and marking of operation events corresponding to the current playback time point, thus eliminating the need for manual switching between progress bar and event list
2Loss of time
If switching between video progress bar and operation event list is required, then event positioning can be achieved, but operational time consumption increases
Solution Approach 1:
The patent performs preliminary synchronization between the video progress bar and operation event list, pre-positioning operation events according to the current playback time point before the user needs to determine any specific event, thereby eliminating the need for time-consuming switching operations
Solution Approach 2:
The patent implements a feedback mechanism where the operation event list is automatically updated and positioned based on the video playback time point, providing real-time feedback to the user about which operation event corresponds to the current playback position, thus eliminating the need for manual switching

AI summary
An operation replay interface including an operation video replay area and an operation event list is output for display. The operation video replay area includes the operation replay video and a playback progress bar. Operation events are displayed in the operation event list. Display of the operation events is synchronized with the playback progress bar. When a first trigger operation is performed on the playback progress bar, a playback indicator is positioned at a first playback time point indicated by the first trigger operation. A display attribute of a first operation event corresponding to the first playback time point is changed. When a second trigger operation is performed on a second operation event in the operation event list, a display attribute of the second operation event in the operation event list is changed. The playback indicator is positioned at a second playback time point corresponding to the second operation event.
