Virtual Whiteboard for Real-Time Multi-User Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current teleconference systems lack effective non-verbal communication methods, leading to difficulties in expressing opinions and emotions, and face challenges with real-time content editing as the number of participants increases, resulting in latency and loss of editing data due to server overload.
Innovation Solution
A method and apparatus that facilitate non-verbal communication through graphical elements and gestures, implement a peer-to-peer network for real-time content editing, and minimize server load by converting content formats for seamless editing without external applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a server-client architecture is used for online collaboration service, then content editing can be managed centrally, but server load and latency increase when multiple users edit simultaneously
Solution Approach 1:
The system divides the collaboration space into multiple sections, with each section independently managed and edited. This segmentation allows parallel processing of editing operations across different sections, reducing overall latency while maintaining centralized coordination through the server.
Solution Approach 2:
A virtual whiteboard is introduced as an intermediary layer between users and the server. The virtual whiteboard handles real-time editing operations locally, reducing the need for constant server communication and thereby decreasing latency while maintaining content management stability.
2Adaptability or versatility
If external applications are called for each content format, then content editing capability is comprehensive, but system complexity and operation difficulty increase
Solution Approach 1:
The virtual whiteboard is designed with multi-functionality to handle various content formats (images, text, videos, audio) within a single unified interface. This eliminates the need for multiple external applications while maintaining comprehensive content editing capability.
Solution Approach 2:
Multiple content editing functions that previously required separate external applications are merged into the virtual whiteboard. This consolidation reduces system complexity while preserving the ability to edit diverse content types.
3Quantity of substance
If traditional teleconference systems are used, then audio and video communication is provided, but non-verbal communication methods are limited
Solution Approach 1:
The system adds a visual dimension to telecommunication by introducing a virtual whiteboard where participants can draw, annotate, and visually express ideas. This transforms the communication from purely auditory to a multi-dimensional experience including visual non-verbal expression.
Solution Approach 2:
The virtual whiteboard serves as a mediator that enables rich non-verbal communication. Participants can use the whiteboard to visually express emotions, ideas, and feedback that would be difficult to convey through audio alone, thereby enhancing non-verbal communication capability.

AI summary
A content joint editing method according to an embodiment of the inventive concept may preserve the real-time property of update of edits as much as possible even if the number of editors increases when multiple editors simultaneously edit content. A content editing method can share and edit various contents without calling a separate external application in an online collaboration service. A content sharing method can manage each user's access rights to a content in individual content units in collaboration service that displays a plurality of contents at the same time in the collaboration space for sharing contents among multiple users.
