Solution Overview

Problem

Existing technologies for evaluating online meetings focus on speech content and emotion, but fail to account for varying attributes of different types of meetings, leading to inconsistent evaluation criteria.

Innovation Solution

An analysis apparatus and method that acquires emotion data from face images, generates analysis data based on meeting attributes, and selects messages for effective meeting management, incorporating emotion data, meeting data, and attribute-specific analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If evaluation is based on speech content and emotion only, then meeting analysis can be performed, but the evaluation criteria become inconsistent across different meeting types

Engineering Contradiction:
Improveevaluation criteria adaptabilityVSAvoidevaluation consistency
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent implements dynamic evaluation criteria that automatically adjust based on meeting attributes. The system determines meeting type (e.g., brainstorming, decision-making, presentation) and selects appropriate evaluation standards for each type, making the evaluation system adaptable while maintaining consistency within each meeting category.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes evaluation parameters according to meeting attributes. Different weightings and criteria are applied based on the determined meeting type, allowing the evaluation system to adapt to different contexts while maintaining precise measurement within each context through standardized parameter sets.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If generic meeting evaluation is used, then simplicity is maintained, but effectiveness for specific meeting types is reduced

Engineering Contradiction:
Improveevaluation simplicityVSAvoidevaluation effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the evaluation process into distinct phases: meeting attribute determination, type classification, and targeted evaluation. This segmentation allows the system to maintain operational simplicity through automated flow control while achieving reliability through specialized evaluation criteria for each meeting type.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs self-service by automatically determining meeting attributes and selecting appropriate evaluation criteria without manual intervention. This maintains ease of operation while ensuring reliability through consistent application of type-specific evaluation standards.

Inventive Principle:
Principle #25Self-service
