Video Timeline Action Curve Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interfaces that present videos lack sufficient information, making it difficult for users to locate specific parts of a video, as they only provide a timeline representation without additional context.
Innovation Solution
A graphical user interface that includes a timeline element and an action curve element, where the action curve represents the action values of an image capture device during video capture, allowing users to visualize and interact with the video progress length and action values, with optional classification elements to identify specific moments within the video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only a timeline representation is provided, then the interface is simple, but users cannot locate specific parts of the video effectively
Solution Approach 1:
The patent adds a new dimension to the traditional timeline interface by introducing an action curve that plots action values against time. This vertical dimension of action intensity information allows users to quickly identify moments of interest without expanding the horizontal timeline, resolving the contradiction between interface simplicity and information completeness.
Solution Approach 2:
The action curve serves as an intermediary visual element between the timeline and the video content itself. It mediates information about video content by translating action values into a visual representation that users can interpret to locate specific moments, bridging the gap between simple timeline navigation and detailed content information.
2Loss of information
If action curve information is added to the timeline, then users can locate specific parts of the video, but the interface complexity increases
Solution Approach 1:
The patent merges the action curve with the existing timeline interface elements, positioning the action curve adjacent to or integrated with the timeline rather than creating a separate interface. This merging approach recovers action information while minimizing the increase in overall interface complexity by utilizing existing spatial arrangements.
3Loss of information
If multiple interface elements are added to convey video information, then content recognition improves, but the interface becomes more complex
Solution Approach 1:
The patent segments the information display into distinct functional elements: the timeline for temporal navigation, the action curve for action intensity visualization, and optional classification elements for content identification. This segmentation allows each element to serve its specific purpose efficiently, recovering comprehensive video information while maintaining clear interface organization.
Data Source
AI summary
A video may be presented with a timeline representation of the video. The timeline representation may enable a user to jump to different parts of the video. An action curve for the video may be presented along the timeline representation. The action curve may include values that represent different actions taken/experienced by an image capture device while capturing the video. The action curve may help the user identify/locate different parts of the video.
