Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing chat systems with pseudo clients lack the ability to animate conversations with responses that reflect the personality of virtual agents, resulting in mechanically uniform and unengaging interactions.

Innovation Solution

An information processing system that includes a virtual agent profile database and a control unit which selects and generates messages from virtual agents based on communication analysis, allowing for personalized responses in real-time communication sessions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a pseudo client is used to automatically respond in chat rooms, then automatic response capability is improved, but the response becomes mechanically uniform and lacks personality

Engineering Contradiction:

Improveautomatic response capabilityVSAvoidresponse personality and adaptability

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The system changes the parameters of virtual agent responses by selecting from multiple pre-defined personality types (e.g., polite, humorous, serious) and adjusting response characteristics based on communication context, user preferences, and situation analysis, thereby transforming uniform automatic responses into personalized interactions

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The virtual agent's response behavior is made dynamic by continuously analyzing communication situations, user profiles, and conversation context to adapt responses in real-time, allowing the same automatic response system to exhibit different personalities and behaviors depending on the situation

Inventive Principle:

Principle #15Dynamics

2Productivity

If uniform automatic responses are given, then response generation speed is improved, but user engagement and conversation animation are reduced

Engineering Contradiction:

Improveresponse generation speedVSAvoiduser engagement and interaction quality

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by pre-defining multiple virtual agent personalities and response templates before actual communication occurs. During real-time interaction, the system quickly selects the appropriate pre-prepared personality and response pattern based on situation analysis, maintaining fast response generation while achieving personalized engagement

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates copies of multiple virtual agent personalities (e.g., polite virtual agent, humorous virtual agent, serious virtual agent) that can be selectively deployed in different communication situations, allowing rapid response generation without sacrificing user engagement for each specific context

Inventive Principle:

Principle #26Copying

AI summary

An information processing system and an information processing method to enable a conversation to be animated with a response of a virtual agent having proper personality corresponding to a communication situation between users. The information processing system includes: a virtual agent profile database that accumulates profiles of a plurality of virtual agents capable of communication on a network; and a controller that selects one virtual agent from the plurality of virtual agents in accordance with an analysis result of communication between real users, generates a message in accordance with the analysis result and the profile of the one virtual agent, and posts the generated message to a communication session between the real users.
