Solution Overview

Problem

Existing emotion estimation methods require biometric data and numerous user inquiries, making them complex and inefficient for estimating user emotions based on subjective mood, excitement, and relaxation degrees.

Innovation Solution

An emotion estimation method that obtains subjective mood, excitement, and relaxation parameters from users and estimates an emotion parameter using a simplified affect grid system, eliminating the need for biometric data and reducing user input, with a content determination system that provides tailored content to induce desired emotions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If biometric data and numerous user inquiries are used for emotion estimation, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveemotion estimation accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts only the essential emotional dimensions (arousal and valence) from complex biometric data, using a simplified affect grid model that requires minimal user input while maintaining estimation accuracy. This reduces system complexity by eliminating unnecessary biometric sensors and processing components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms complex biometric parameters into simplified emotional parameters using established psychological models (affect grid). By changing the parameter representation from physiological measurements to psychological constructs, the system achieves accurate emotion estimation with reduced complexity.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If biometric data collection is implemented, then measurement precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveemotion estimation accuracyVSAvoiduser input burden
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent extracts only the minimal necessary user inputs (arousal and valence ratings) required for emotion estimation, eliminating the need for extensive biometric data collection and numerous user inquiries. This significantly reduces user input burden while maintaining measurement precision through the use of established affect grid methodology.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If simplified parameter collection is used, then ease of operation is improved, but measurement precision deteriorates

Engineering Contradiction:
Improveuser input burdenVSAvoidemotion estimation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent changes the parameter collection approach from complex biometric measurements to simplified psychological ratings based on the affect grid model. This transformation maintains measurement precision by using validated psychological constructs while dramatically improving ease of operation through minimal user input requirements.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces the affect grid model as an intermediary framework that translates simple user ratings into accurate emotion estimates. This mediator enables precise measurement without requiring direct complex biometric data collection, thus maintaining accuracy while improving ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An emotion estimation method includes: obtaining a first parameter indicating a user's subjective mood, a second parameter indicating the user's subjective excitement degree, and a third parameter indicating the user's subjective relaxation degree; estimating an emotion parameter indicating the user's emotion based on the obtained first parameter, second parameter, and third parameter; and outputting information related to the emotion parameter.
