Arousal State Determination for Objective Mental Care Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mental care services rely on subjective judgments and lack an objective mental state index, making it difficult to provide appropriate feedback and maintain long-term motivation, as they insufficiently determine the complex mental state of humans.
Innovation Solution
An information processing apparatus and method that determines a user's arousal state among hyperarousal, optimal arousal, and hypoarousal using physiological, subjective, and behavioral indices, and generates feedback based on the Polyvagal theory to guide the arousal state towards optimal levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If subjective judgment is used for mental care services, then ease of operation is improved, but measurement precision of mental state deteriorates
Solution Approach 1:
The patent replaces the mechanical/manual system of subjective judgment with an automated information processing system that objectively measures mental state using physiological indices. The arousal state determination unit automatically calculates arousal state based on measured data, substituting human subjective assessment with objective computational analysis.
2Device complexity
If only simple arousal state measurement is used, then device complexity is reduced, but measurement precision of complex mental state deteriorates
Solution Approach 1:
The patent segments the complex mental state measurement into distinct components: physiological index measurement (respiration rate, heart rate), subjective index collection (self-assessment questionnaires), and behavioral index observation. Each component is measured and processed separately, then integrated to determine the overall arousal state, making the complex measurement manageable and accurate.
Solution Approach 2:
The patent uses multiple physiological parameters (respiration rate, heart rate variability) and transforms them into meaningful indicators of arousal state. By changing and combining multiple parameters rather than relying on a single measure, the system achieves precise measurement of complex mental state while maintaining reasonable device complexity.
3Measurement precision
If objective mental state index is introduced, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The information processing apparatus is designed to perform multiple functions: measuring physiological indices, collecting subjective indices, observing behavioral indices, calculating arousal state, and providing feedback. This multi-functional device consolidates what could be separate complex systems into a single integrated platform, achieving precise objective measurement while managing overall system complexity.
Solution Approach 2:
The system incorporates self-service elements where users independently complete self-assessment questionnaires and the system automatically processes all data without requiring external expert intervention. This reduces the need for complex manual assessment procedures and specialized equipment, achieving objective measurement with manageable complexity.
4Productivity
If feedback is provided without accurate arousal state determination, then productivity is maintained, but reliability of feedback deteriorates
Solution Approach 1:
The patent implements a closed-loop feedback system where the arousal state determination unit continuously monitors physiological and behavioral indices, calculates the current arousal state, and provides feedback to the user. This feedback enables users to adjust their state and achieve optimal arousal levels, ensuring both reliable feedback and maintained productivity through continuous optimization.
Data Source
AI summary
There is provided an information processing apparatus, an information processing method, and a program enabling to present more appropriate feedback. An arousal state determination unit determines which state among hyperarousal, optimal arousal, and hypoarousal an arousal state of a user is in, and a feedback information generation unit generates feedback information for the user on the basis of the determined arousal state. The technology according to the present disclosure can be applied to, for example, a wearable device.
