Comment Overlay Apparatus for Spatial Video Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively overlay user comments with location-specific information onto video imagery of events, particularly in virtual or augmented reality, making it difficult for viewers to associate comments with their corresponding locations and times during the event.
Innovation Solution
An apparatus and method that utilize processor and memory configurations to overlay comments on video imagery based on location and time information, allowing comments to be displayed at positions corresponding to the commenting user's location and time of submission, even if the user is moving or the event is recorded, using satellite, land, or indoor positioning systems, and context analysis to determine the relevance of comments to specific occurrences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If comments are overlaid on video imagery without location information, then the display is simple and straightforward, but viewers cannot associate comments with their corresponding locations and times
Solution Approach 1:
The system performs preliminary actions by obtaining location information from positioning systems (GPS, indoor positioning) and time information from event data before displaying comments. This pre-processing ensures that when comments are overlaid on video imagery, they are already associated with the correct location and time, allowing viewers to accurately associate comments with specific moments and positions in the event without requiring complex real-time processing during playback.
Solution Approach 2:
The system introduces an intermediary mechanism that processes and correlates location information, time information, and comment data before overlaying them on the video imagery. This intermediary layer acts as a mediator between the raw data sources (positioning systems, event data) and the final display, managing the complexity of data integration while presenting a unified view to the user where comments are automatically positioned and timed correctly.
2Measurement precision
If the system tracks moving users and updates comment positions in real-time, then location accuracy is improved, but processing requirements and system complexity increase
Solution Approach 1:
The system applies dynamics by enabling comment positions to change dynamically as users move during the event. When a user's location changes, the system automatically updates the comment position in the video imagery to reflect the new location. This dynamic adjustment maintains measurement precision for moving users without requiring a completely static display approach, allowing the system to adapt to real-time movements while managing complexity through automated position recalculation based on updated location data.
3Loss of information
If all comments are displayed for the entire event duration, then information completeness is maintained, but information overload and user confusion increase
Solution Approach 1:
The system implements periodic action by displaying comments only during specific time periods when they are relevant to the event. Each comment is associated with time information indicating when it was made or when it applies, and the system controls the display to show comments only during their applicable time windows. This periodic display approach maintains information completeness by ensuring all relevant comments are shown at appropriate times while preventing information overload by excluding irrelevant comments from the display during periods when they do not apply.

AI summary
An apparatus caused to: in respect of video imagery of an event at which one or more commenting users are present and have submitted comments, a location of the or each of the one or more commenting users visible in the video imagery; based on a current view of the video imagery provided for display to a user and at least one comment having location information associated therewith indicative of one or more of (i) the location, at the time of making the comment, of the commenting user who submitted the comment at the event, (ii) a location, at the event, specified by the commenting user who submitted the comment at the event; provide for display of the comment overlaid over the current view of the video imagery, the comment displayed in the current view of the video imagery at a position that corresponds to the location information.
