Solution Overview

Problem

Existing systems struggle to accurately determine mutual congeniality between individuals, relying on action history, preference, and attribute information which is often uncertain and leads to opportunity losses in building interpersonal relationships.

Innovation Solution

An information processing system that estimates emotional information about a target living body using biological and motion information acquired by sensors, and displays this information to facilitate more accurate inference of congeniality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If action history, preference information, and attribute information are used to determine mutual congeniality, then relationship building can be attempted, but the determination accuracy is low and uncertainty remains high

Engineering Contradiction:

Improvedetermination accuracy of mutual congenialityVSAvoiduncertainty in inference

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent replaces traditional mechanical/inferential methods (analyzing action history, preferences, and attributes) with a biological sensing system that directly measures emotional states through sensors detecting physiological signals, thereby substituting indirect inference with direct measurement

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces sensors as an intermediary between the subjects and the determination process, using physiological signal detection as a mediating mechanism to objectively capture emotional information that bridges the gap between subjective states and objective measurement

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If traditional inference methods are used, then relationship building can be initiated, but opportunity losses occur due to uncertainty

Engineering Contradiction:

Improveefficiency of relationship buildingVSAvoidopportunity loss

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary measurement of emotional states before relationship building decisions are made, allowing users to have advance knowledge of congeniality compatibility, thereby preventing wasted time and opportunities on incompatible relationships

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If objective emotional information is measured using sensors, then determination accuracy improves, but device complexity increases

Engineering Contradiction:

Improveprecision of emotional information measurementVSAvoidcomplexity of sensing system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs sensors with multi-functionality that can detect various physiological signals (heart rate, skin conductance, temperature, etc.) to infer multiple emotional dimensions, allowing a single device to perform comprehensive emotional measurement without requiring separate specialized sensors for each parameter

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Provided is an information processing system that includes an estimation section and a display section. The estimation section estimates emotional information about a target living body on the basis of at least one of biological information or motion information about the target living body acquired by a sensor. The display section displays the emotional information on a display surface.
