Solution Overview
Problem
Existing stress management technologies only consider stress levels without identifying the factors causing stress, making it difficult to control stress effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only stress level measurement is implemented without factor analysis, then the system simplicity is maintained, but the stress control precision deteriorates
Solution Approach 1:
The stress control system is segmented into two functional modules: a stress level measuring unit that monitors physiological parameters (heart rate, respiration, skin conductance) and a stress factor specifying unit that analyzes user actions and environmental context. This segmentation allows the system to maintain operational simplicity while achieving precise stress control by addressing different aspects separately.
Solution Approach 2:
User actions serve as an intermediary element that connects stress level measurement with stress factor identification. The stress factor specifying unit uses detected user actions (typing, scrolling, voice commands) as mediators to infer stress causes without requiring direct physiological measurement of stress factors, thus maintaining system simplicity while improving precision.
2Measurement precision
If stress factor specification based on user actions is added, then the stress control precision is improved, but the device complexity increases
Solution Approach 1:
The sensor unit performs multiple functions: it detects both physiological parameters for stress level measurement and user actions for stress factor specification. This multi-functionality reduces the need for separate dedicated sensors, thereby limiting the increase in device complexity while achieving improved stress control precision through comprehensive data collection.
Solution Approach 2:
The stress factor specifying unit utilizes user actions that occur naturally during device usage (typing, scrolling, voice commands) rather than requiring separate explicit inputs. The system self-services by converting routine interaction data into stress factor information, avoiding additional complexity from dedicated stress factor input mechanisms.
3Measurement precision
If comprehensive sensor data analysis is performed, then the stress level measurement accuracy is improved, but the processing time increases
Solution Approach 1:
User actions are detected and preliminary analysis is performed continuously in the background before stress level thresholds are exceeded. By preparing action data in advance and maintaining a ready state for stress factor specification, the system reduces the processing time required when actual stress control decisions need to be made, while still performing comprehensive analysis for accuracy.
Solution Approach 2:
The system performs partial analysis of sensor data by focusing on the most relevant parameters and user actions at any given moment rather than analyzing all possible data points equally. This selective approach maintains measurement accuracy for critical stress indicators while reducing overall processing time by excluding less relevant data analysis.

AI summary
The present technology relates to information processing apparatus and method, and a program that make a stress level controllable depending on circumstances. A stress level measuring unit measures a stress level of a user on the basis of a result of detection by various types of sensors included in an input unit. A stress factor specifying unit specifies a factor causing an increase or decrease in the stress level on the basis of an action of the user in a period in which the stress level is increased or decreased. The present technology is applicable to a stress control system, for example.
