Video Annotation With Paused Frame And Live Stream
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During video calls, users annotating a video frame are unaware of the actions or environment of the other user, which can be problematic in scenarios like remote surgery assistance.
Innovation Solution
A method and device that allow users to pause the video stream for annotation, enabling them to view and annotate the paused frame while continuing to display the live video stream, with annotation information sent to the other user device in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the video stream is paused for annotation, then the user can focus on annotating the paused frame, but the user becomes unaware of what is happening at the other end of the video call
Solution Approach 1:
The video stream is segmented into two separate displays: a paused video frame for annotation and a continuing live video stream for situational awareness. This segmentation allows the user to focus on annotation tasks while simultaneously monitoring the live feed, resolving the contradiction between annotation precision and situational awareness.
Solution Approach 2:
A picture-in-picture display is introduced as an intermediary element that shows the live video stream within the paused video frame interface. This intermediary provides continuous visual feedback about the other end of the call, maintaining situational awareness while enabling precise annotation work on the paused frame.
2Manufacturing precision
If the user annotates the paused video frame, then annotation detail can be improved, but the collaboration real-time interaction is reduced
Solution Approach 1:
The live video stream continues to play in the picture-in-picture display while the user annotates the paused frame. This continuity ensures that real-time collaboration is maintained, as both users can see each other's actions and the annotation process occurs without interrupting the overall video call flow.
Solution Approach 2:
Annotations made on the paused video frame are transmitted in real-time to the other user device, providing immediate feedback. The other user can see the annotations being applied and respond accordingly, maintaining collaborative efficiency while allowing detailed annotation work.
3Ease of operation
If only the paused video frame is displayed, then annotation focus is improved, but the user loses context of the ongoing video call
Solution Approach 1:
The interface transitions from a single-dimensional display to a multi-dimensional display by incorporating a picture-in-picture view. The paused video frame occupies the main dimension for annotation, while the live video stream is embedded in a smaller dimension, providing both annotation focus and video call context simultaneously.
Data Source
AI summary
A user device has a display, a user interface and a network interface. The network interface receive a video data stream from another user interface. A user of the user device is able to pause the video stream. The paused image of the video stream and the video stream are both displayed on the display. The user is able to annotate the paused image.
