Solution Overview

Problem

Existing detection technologies for a living body state do not accurately obtain information about a person's emotional or affective state, leading to inadequate process reflection.

Innovation Solution

A detection device and method that performs constituent analysis on tears to detect a living body state, predict affective state transitions, and calculate emotion levels, allowing for accurate detection and prediction of emotional states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If environmental information around the user is acquired to determine behavior characteristic, then the detection process can be performed, but the detection accuracy of living body state is insufficient

Engineering Contradiction:
Improvedetection accuracy of living body stateVSAvoidinformation about living body state
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent extracts specific substances (hormones, metabolites, proteins, amino acids, peptides, nucleic acids, lipids, carbohydrates) from tear fluid for analysis. By focusing on extracting and analyzing these specific biochemical markers rather than general environmental information, the system achieves direct detection of the user's emotional and physiological state, thereby improving measurement precision while obtaining accurate living body state information.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If only behavior characteristic is determined from environmental information, then the detection device can operate, but appropriate process reflection cannot be performed

Engineering Contradiction:
Improveappropriateness of process reflectionVSAvoidinformation about living body state
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the detection results of biochemical substances in tear fluid are used to determine the user's emotional state and behavior characteristics, which then trigger appropriate process reflections. This closed-loop feedback system ensures that the process reflection is reliably aligned with the actual living body state by continuously monitoring biochemical markers and adjusting responses accordingly.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If constituent analysis of tears is performed, then accurate detection of living body state is achieved, but the device complexity increases

Engineering Contradiction:
Improvedetection accuracy of living body stateVSAvoidcomplexity of analysis device
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a multi-functional analysis device that can detect multiple types of biochemical substances (hormones, metabolites, proteins, amino acids, peptides, nucleic acids, lipids, carbohydrates) simultaneously through a single integrated system. This universal device performs constituent analysis of tears comprehensively, achieving accurate detection of living body state while consolidating multiple detection functions into one apparatus, thereby managing device complexity through functional integration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present technology relates to a detection device, a detection method, and a program capable of detecting a living body state of a human body easily and accurately. A contact lens type display device is provided with a tear detection unit 26 to collect tears on an eyeball and to analyze a constituent and detect affective information of a user. The detection result is sent from the contact lens type display device 11 to a mobile terminal SP and displayed on the mobile terminal SP. Consequently, the living body state can be detected on the basis of the constituent of the tears of the user, whereby the living body state of the user can be accurately detected. The present technology can be applied to a contact lens type display unit.
