Communication Management System for Shared Stroke Image Operation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conference systems where multiple terminal apparatuses share a stroke image, there is a challenge in preventing unintended operations on the shared stroke image, particularly when multiple users are interacting simultaneously, leading to operations different from the intended actions.
Innovation Solution
A communication management system that manages stroke information and restricts operations on designated stroke data based on group operation information received from one terminal apparatus, ensuring that only authorized operations are performed on the shared stroke image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple terminal apparatuses share stroke image simultaneously, then collaborative interaction efficiency is improved, but unintended operations on shared stroke image occur
Solution Approach 1:
The communication management system acts as an intermediary between multiple terminal apparatuses, receiving operation information from one terminal and restricting operations from other terminals. This mediator mechanism enables collaborative interaction while preventing unintended operations, resolving the contradiction between efficiency and reliability.
Solution Approach 2:
The system dynamically adjusts operation permissions based on real-time operation information. When operation information is received from a specific terminal, the system dynamically restricts operations on the same stroke data from other terminals, allowing flexible collaborative interaction while maintaining operation integrity.
2Reliability
If operation restriction is implemented on shared stroke image, then operation integrity is maintained, but system complexity increases
Solution Approach 1:
The communication management system performs multiple functions: managing stroke information, receiving operation information, and restricting operations. By consolidating these functions in a single system, the patent avoids the complexity that would arise from implementing restriction mechanisms in each terminal apparatus individually.
Solution Approach 2:
The communication management system serves as a centralized intermediary that handles all operation restriction logic. This centralization simplifies the overall system architecture compared to distributed restriction mechanisms, as each terminal only needs to send operation information without implementing complex local restriction logic.

AI summary
A communication management system manages a session in which a plurality of terminal apparatuses shares a stroke image. The communication management system includes circuitry configured to: manage stroke information including a plurality of pieces of stroke data representing the stroke image; receive, from a first terminal apparatus, group operation information for designating one or more pieces of stroke data, which are operation targets, from among the plurality of pieces of stroke data; and restrict, based on the group operation information, an operation regarding the one or more pieces of stroke data by a second terminal apparatus, which is different from the first terminal apparatus.
