Collaborative Presentation Sharing for Real-Time Meeting Unity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional meeting assistance systems lack bidirectionality and unity as participants cannot simultaneously operate and share a presentation document during a meeting.
Innovation Solution
A meeting assistance system that allows multiple participants to operate and share a presentation document in real time through a presentation document storage unit, authority imparting unit, and document sharing unit, enabling real-time updates based on participant and speaker operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional meeting assistance system is used, then the system structure is simple, but participants cannot simultaneously operate and share a presentation document in real time, lacking bidirectionality and unity
Solution Approach 1:
The system divides the presentation document into multiple editable regions or sections that can be simultaneously operated on by different participants. Each participant can work on specific portions of the document independently while changes are shared in real-time across all users, enabling simultaneous operation without conflict.
Solution Approach 2:
The system introduces a server or cloud-based intermediary that mediates between multiple participants and the presentation document. This intermediary receives operations from participants, manages document state, and distributes updates to all connected users, enabling real-time collaborative editing while maintaining system coordination.
2Adaptability or versatility
If multiple participants are allowed to operate the presentation document simultaneously, then bidirectionality and unity are achieved, but system complexity increases
Solution Approach 1:
The system creates a universal document platform that can handle multiple operation types (editing, commenting, presenting) and support multiple participants simultaneously. This multi-functional platform provides a unified interface for all participants regardless of their specific role or operation type, simplifying the user experience despite the underlying complexity.
Solution Approach 2:
The system implements real-time feedback mechanisms where changes made by any participant are immediately reflected for all other participants. This continuous feedback loop ensures all users see the current document state, enabling coordinated collaboration while the system automatically manages version control and conflict resolution.
3Productivity
If real-time sharing of updated presentation document is implemented, then participant engagement and unity improve, but data synchronization complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing document templates, permission structures, and synchronization protocols before participants begin collaborating. This preparation work is done in advance to reduce the complexity of real-time operations during actual document editing sessions.
Solution Approach 2:
The system uses copying mechanisms where the presentation document is replicated across multiple user sessions and devices. Each participant receives a local copy or view of the document that can be edited independently, with changes then synchronized back to the central document, enabling real-time collaboration while managing data consistency.

AI summary
To provide a meeting assistance system capable of imparting bidirectionality and a sense of unity to a meeting. A meeting assistance system includes: a presentation document storage unit 3 that stores a presentation document; an authority imparting unit 5 that grants document manipulation rights to a participant; a document sharing unit 7 for sharing the presentation document with participants; and a presentation document updating unit 9 that, on the basis of a manipulation from one or more authorized participants to which document manipulation rights have been granted, manipulates and updates the presentation document stored in the presentation document storage unit 3. When the document sharing unit 7 is sharing a first presentation document with a plurality of participants, if one or more authorized participants manipulates the first presentation document, the updated first presentation document is shared in real time with the plurality of participants.
