Spatial-Region Controls for Individualized Video Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conference systems cannot allow a presenter to direct a specific portion of shared content to one viewer without affecting all other viewers, requiring separate presentation sessions and increased management for the presenter.
Innovation Solution
Implementing spatial-region specific controls that enable a presenter to individualize the presentation for a given viewer by generating auxiliary data based on user input, allowing specific regions of the presentation to be displayed on user devices without showing other regions, using features like drag-and-drop functionality to create customized auxiliary streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a presenter directs a specific portion of shared content to one viewer in existing systems, then all other viewers are also directed to the same content portion, but the presenter cannot individualize the presentation for different viewers
Solution Approach 1:
The shared content is divided into multiple spatial regions, and the system generates separate auxiliary video streams for each spatial region. This allows the presenter to direct different spatial regions to different viewers within the same presentation session, enabling individualized presentations without requiring separate sessions for each viewer.
Solution Approach 2:
The system introduces an intermediary mechanism that processes the shared content stream and generates customized auxiliary streams for individual viewers. This intermediary layer enables the presenter to specify which spatial region each viewer should see, while the system handles the complex stream generation and distribution, reducing the management burden on the presenter.
2Adaptability or versatility
If separate presentation sessions are established for different users to provide customized content, then each user receives individualized presentation, but the presenter must manage multiple sessions increasing complexity
Solution Approach 1:
The system merges multiple presentation sessions into a single unified session by implementing spatial-region specific controls. Multiple viewers can simultaneously receive customized content within the same session, eliminating the need for the presenter to manage separate sessions for each user and reducing the time required for session management.
3Ease of operation
If all viewers receive the same shared content, then system simplicity is maintained, but viewers are exposed to irrelevant information reducing user experience
Solution Approach 1:
The system applies local quality by generating customized auxiliary streams that provide different spatial regions of the shared content to different viewers based on their specific needs. This allows each viewer to receive only the relevant information without being distracted by irrelevant content, while maintaining system simplicity through a unified presentation session with spatial-region specific controls.
Data Source
AI summary
In some embodiments, a shared presentation, which includes a set of spatial regions, is transmitted to user devices associated with users. Then, based on a user input indicating a first spatial region of the shared presentation for a first user, first auxiliary data (e.g., auxiliary video stream of the shared presentation) that corresponds to the first spatial region is generated. Moreover, based on the user input indicating the first user, a first user device associated with the first user is caused to display the first spatial region at a first time without displaying one or more other spatial regions of the set of spatial regions at the first time. As an example, the first auxiliary data is transmitted to the first user device, which causes the first user device to display the first spatial region without displaying the other spatial regions.
