Solution Overview

Problem

Existing systems fail to accurately determine an appropriate approach to a subject based on their state and task execution situation, particularly when tasks are performed continuously or intermittently.

Innovation Solution

An information processing device that acquires task evaluation information, estimates the subject's state, and determines an intervention mode based on this information to optimize task execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the system provides a standardized approach to all subjects, then the system operation is simple, but the task execution efficiency is reduced due to lack of personalization

Engineering Contradiction:

Improvetask execution efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary estimation of the subject's state (such as concentration level, fatigue level, or emotional state) before determining the approach. This allows the system to pre-adjust the approach based on the estimated state, achieving personalized treatment without complex real-time adjustments during task execution

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically determines the approach based on the estimated subject state and task evaluation information. The approach is not fixed but adapts according to the subject's current state, allowing the system to optimize task execution efficiency while maintaining manageable complexity through rule-based adaptation

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If the system collects comprehensive data about the subject, then the determination accuracy is improved, but the information processing load increases

Engineering Contradiction:

Improvestate estimation accuracyVSAvoidcomputational resource consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system extracts only the necessary features from the collected subject data that are relevant for state estimation. Instead of processing all available data, it selectively extracts key indicators (such as facial expression features, voice tone features, or specific physiological parameters) to reduce computational load while maintaining estimation accuracy

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system applies different levels of data collection and processing to different aspects of subject state estimation based on their importance. Critical state parameters receive more comprehensive measurement and processing, while less critical parameters use simpler measurement methods, optimizing the balance between accuracy and resource consumption

Inventive Principle:

Principle #3Local quality

AI summary

An information processing device 1X mainly includes an acquisition means 15X, an estimation means 16X, and a determination means 17X. The acquisition means 15X acquires task evaluation information relating to evaluation of execution of a task executed by a subject. The estimation means 16X estimates a state of the subject in execution of the task. The determination means 17X determines a mode of an approach to the subject based on the task evaluation information and the state of the subject. The device can support decision making regarding intervention in a subject's task execution.
