Conference System Shared Personal Note Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conference systems lack the ability to efficiently manage and display shared and personal notes during remote conferences, leading to inefficiencies in document collaboration and communication among participants.
Innovation Solution
A conference system with a terminal that displays documents and allows participants to input notes, featuring a document storage unit that separates shared and personal overwrite data, enabling selective reading and display of these notes, and a control device that manages document access and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all participant notes and shared notes are transmitted to each terminal, then complete information is available, but communication traffic increases significantly
Solution Approach 1:
The patent segments notes into two distinct types: shared notes (visible to all participants) and personal notes (visible only to the individual participant). This segmentation allows the system to transmit only the necessary information to each terminal, reducing communication traffic while maintaining information completeness. Each terminal receives shared notes from all participants and can send personal notes, eliminating the need to transmit all participants' personal notes to every terminal.
Solution Approach 2:
The patent implements local quality by making note visibility dependent on the viewer's perspective. Shared notes have global visibility while personal notes have local visibility restricted to their author's terminal. This differentiated quality control optimizes information distribution, ensuring each participant receives only the information relevant to their role, thereby reducing overall communication traffic while preserving complete information access where needed.
2Loss of information
If multiple types of data (shared notes, personal notes, document images) are managed separately, then data organization is improved, but device complexity increases
Solution Approach 1:
The patent merges the management of different data types (shared notes, personal notes, and document images) into a unified note management system. The system handles all these data types through common processing mechanisms for storage, transmission, and display, reducing device complexity while maintaining effective data organization. The unified approach allows consistent handling of mixed data types without requiring separate complex management structures for each type.

AI summary
A conference system includes a terminal that displays a document presented by a presenter in a conference and that is capable of receiving writing inputs from a participant for enabling exchange of opinions, and a document storage unit that stores the document used in the conference and the written information. The document storage unit stores image data of respective pages of the document, shared overwrite data for each page including shared written information written by the presenter or participants, and personal overwrite data for each participant provided for each page and including personal memo information written by the participant. The terminal includes a read unit that selectively reads out from the document storage unit, concerning each page, the image data of the presented document, the shared overwrite data, and a participant's personal overwrite data, and a display controller that overlaps the read-out data and displays the overlapped data on a display.
