Chronological Event List for Video Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in following and navigating through multimedia content, such as video tutorials, due to quick pacing and small dimensions, leading to missed important details and time-consuming searches for replaying relevant sections.
Innovation Solution
A method for generating chronological event information by receiving event data associated with different positions in a video stream, displaying current, previous, and next events in an event list, and updating the playhead position upon user selection, allowing efficient navigation and interaction with multimedia content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the video tutorial moves quickly to cover more content, then the productivity of information delivery is improved, but the user's ability to follow and understand commands deteriorates
Solution Approach 1:
The patent segments the continuous video stream into discrete, identifiable events (command selections, menu interactions, button clicks). Each event is extracted and displayed as a separate item in an event list, allowing users to process information in manageable chunks rather than trying to follow continuous fast-paced narration.
Solution Approach 2:
The system performs preliminary action by pre-processing the video stream to identify and extract all command events before the user needs them. The event list is generated in advance and made available for user interaction, so when users need to review commands, the information is already prepared and organized for easy access.
2Productivity
If the video tutorial dimensions are small to fit more content on screen, then the productivity of content display is improved, but the user's ability to observe details deteriorates
Solution Approach 1:
The patent introduces an intermediary event list that acts as a mediator between the small video display and the user's need for detailed information. Instead of requiring users to directly observe small UI elements in the video, the event list provides enlarged, clear text representations of all commands and interactions, making details easily detectable without increasing video dimensions.
3Loss of information
If the user searches through the video to locate and replay relevant sections, then the completeness of information review is improved, but the time required deteriorates
Solution Approach 1:
The patent extracts the essential command information from the video stream and places it into a separate event list. This extraction allows users to access command information without needing to navigate through the entire video. Users can simply review the event list to see all commands in sequence, eliminating the time-consuming process of searching and replaying video sections.
Solution Approach 2:
The patent transitions command information from the temporal dimension (video playback sequence) to a spatial dimension (scrollable event list). Instead of reviewing commands through time-based video playback, users can spatially navigate the event list by scrolling, providing a different dimension of access that is much faster and more efficient for review purposes.
4Loss of information
If comprehensive narration is included in the video tutorial, then the completeness of instruction is improved, but the user's ability to track current commands deteriorates
Solution Approach 1:
The patent implements feedback by providing real-time updates to the event list as the video plays. The system continuously monitors the video stream and updates the event list to reflect the current command being demonstrated, giving users immediate feedback about what command is currently active. This helps users track the narrator's progress without having to rely solely on audio cues.

AI summary
Disclosed is a technique for generating chronological event information. The technique involves receiving event data comprising a plurality of events, where each event is associated with a different position in a video stream. The technique further involves determining that a current playhead position in the video stream corresponds to a first position associated with a first event, and, in response, causing the first event to be displayed in an event list as a current event, causing a second event to be displayed in the event list as a previous event, where the second event is associated with a second position in the video stream that is before the first position, and causing a third event to be displayed in the event list as a next event, where the third event is associated with a third position in the video stream that is after the first position.
