Solution Overview

Problem

Existing technologies for inferring interpersonal stressor actions have low identification accuracy.

Innovation Solution

An information processing device that utilizes personality information, stress information, and action information to identify stressor actions by comparing these data types against a stressor action identification table, thereby enhancing the accuracy of stressor action identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If life-log data is used to infer stressor actions, then the system can identify interpersonal stress types, but the identification accuracy of stressor actions remains low

Engineering Contradiction:
Improveidentification accuracy of stressor actionVSAvoidpersonality information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent combines multiple data types (life-log data, personality information, stress information) into an integrated analysis system. The stressor action identification table merges personality traits with action patterns to create a comprehensive identification framework that overcomes the limitations of using life-log data alone.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The stressor action identification table serves as an intermediary structure that connects personality information with observed actions. This table acts as a bridge that translates raw data into meaningful stressor action identifications, improving accuracy by incorporating personality as a mediating factor.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If only life-log data is used for stressor action identification, then the system complexity is low, but the identification accuracy is insufficient

Engineering Contradiction:
Improveidentification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the stressor action identification process into distinct components: personality information processing, stress information processing, action information processing, and integration through the identification table. This segmentation allows each component to be optimized independently while maintaining overall system manageability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameters used for identification from solely behavioral life-log data to a multi-dimensional parameter set including personality traits, stress levels, and action patterns. This parameter expansion significantly improves identification accuracy while the structured approach keeps complexity manageable.

Inventive Principle:
Principle #35Parameter changes

AI summary

An information processing device includes an acquisition unit that acquires a stressor action identification table indicating a correspondence relationship between personality information and action information, personality information indicating personality of a first user, stress information as information regarding stress on the first user, and action information indicating an action of a second user and an identification control unit that judges whether a relationship between the personality information and the action information has been registered in the stressor action identification table or not based on the stress information if a stress value is greater than or equal to a predetermined threshold value and identifies the action information as a stressor action if the relationship has been registered in the stressor action identification table.
