Solution Overview

Problem

In remote multiplex conversations, users find it difficult to understand and participate in different ongoing topics due to the complexity of multiple voices and the lack of clear topic identification.

Innovation Solution

An information processing device with a display processing unit that analyzes multiplex conversation data to identify ongoing topics and displays them using summary titles, allowing users to easily recognize and participate in topics of interest.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple users participate in remote multiplex conversation simultaneously, then conversation diversity and user engagement increase, but it becomes difficult for users to understand and participate in different ongoing topics

Engineering Contradiction:
Improveconversation diversityVSAvoidtopic identification difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the multiplex conversation into distinct topics by analyzing conversation data and identifying different discussion threads. Each topic is separated and presented independently to users, allowing them to easily identify and participate in specific topics of interest without being overwhelmed by the overall conversation complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary system (the information processing device) that mediates between the multiple users and the conversation topics. This intermediary automatically analyzes conversation data, identifies ongoing topics, and presents them to users in an organized manner, relieving users of the burden of manually tracking multiple conversation threads.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If all conversation voices are transmitted to users, then complete information is provided, but voice congestion occurs and users cannot distinguish different topics

Engineering Contradiction:
Improveinformation completenessVSAvoidvoice congestion
Core Design Contradiction:
Loss of informationVSObject-generated harmful factors

Solution Approach 1:

The patent extracts relevant topic information from the complete conversation data and presents only the essential topic summaries to users. By taking out and highlighting key topic elements rather than transmitting all raw conversation voices, the system maintains information completeness while eliminating voice congestion and making topic distinction possible.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by providing different information presentations to different users based on their interests and participation patterns. Each user receives customized topic information that is locally optimized for their needs, allowing complete information to be distributed in a tailored manner that avoids congestion while maintaining comprehensiveness.

Inventive Principle:
Principle #3Local quality

3Loss of information

If users try to track multiple conversation topics manually, then they can understand different topics, but it requires excessive cognitive effort and time

Engineering Contradiction:
Improvetopic understandingVSAvoidcognitive effort time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent performs preliminary action by automatically analyzing and organizing conversation topics before presenting them to users. The system pre-processes the conversation data, identifies ongoing topics, and prepares topic summaries in advance, so users receive ready-to-understand topic information without needing to invest cognitive effort in manual tracking and analysis.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by enabling the system to automatically manage topic identification and presentation without user intervention. The information processing device autonomously monitors the multiplex conversation, detects new topics, and updates topic information, freeing users from the burden of manual topic tracking and reducing their time investment.

Inventive Principle:
Principle #25Self-service

AI summary

The present technology assists a user in having an effective conversation in remote multiplex conversation.A display processing unit performs processing of displaying, on the basis of a result of topic analysis processing of identifying an ongoing topic on the basis of multiplex conversation data and giving a title indicating a summary of each topic, the ongoing topic using the title. The user in remote multiplex conversation can easily recognize not only a topic in which the user is participating but also other topics that are ongoing at the same time, and can easily find an ongoing topic of interest and newly participate in the topic. The present technology is therefore capable of assisting the user in having an effective conversation in the remote multiplex conversation.
