Solution Overview
Problem
Current content evaluation methods rely on subjective and unreliable human surveys, which are inconsistent and emotionally dependent, lacking objectivity in assessing engagement and emotional reactions to content such as games, movies, and advertisements.
Innovation Solution
A content evaluation system and method utilizing a brainwave detector, bio signal detector, and controller to objectively measure and analyze brainwave and bio signals, determining the degree of engagement and emotional reactions, and evaluating content based on these measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If human surveys are used for content evaluation, then ease of operation is improved, but measurement precision and reliability deteriorate due to subjective and emotionally dependent results
Solution Approach 1:
The patent replaces the mechanical system of human surveys with a physiological measurement system using brainwave detectors and bio signal detectors. This substitution captures objective physiological data (brainwave signals, heart rate, skin conductance) that directly reflect engagement and emotional reactions, eliminating the subjectivity inherent in human self-reporting while maintaining ease of operation through automated detection and analysis.
2Measurement precision
If brainwave detectors and bio signal detectors are used, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional integrated system where a single controller performs multiple functions: receiving brainwave signals from the brainwave detector, receiving bio signals from the bio signal detector, detecting changes in both signal types, determining engagement degree, determining emotional reactions, and evaluating content. This consolidation of multiple functions into one controller reduces overall system complexity despite using advanced detection devices.
Solution Approach 2:
The controller serves as an intermediary that bridges the complex detection devices (brainwave detector and bio signal detector) and the evaluation process. It automatically processes the physiological signals, applies analysis algorithms, and generates engagement and emotional reaction metrics, thereby shielding users from the complexity of raw signal processing while maintaining high measurement precision.
3Device complexity
If subjective survey methods are used, then device complexity is reduced, but reliability and objectivity of evaluation deteriorate
Solution Approach 1:
The patent replaces the simple but unreliable mechanical system of human surveys with a physiological measurement system that captures objective biological data. Brainwave detectors measure neural activity patterns, while bio signal detectors monitor cardiovascular and sudomotor responses, providing reliable and objective indicators of engagement and emotional reactions that are not influenced by subjective self-reporting biases.
Solution Approach 2:
The system continuously monitors physiological signals and provides real-time feedback about engagement levels and emotional reactions. The controller detects changes in brainwave and bio signals, determines engagement degree and emotional reactions based on these changes, and uses this feedback to evaluate content effectiveness, creating a closed-loop system that continuously refines its assessment based on actual physiological responses.
Data Source
AI summary
A reliable content evaluation method and system are disclosed. The system includes a brainwave detector, a bio signal detector, a first controller, and a second controller. The brainwave detector detects a brainwave signal of a subject provided with content and outputs a result. The bio signal detector detects bio signals of the subject and outputs a result. The first controller can modify the brainwave and the bio signals to a signal level available for the second controller. The second controller detects change of the brainwave signal and the bio signal through an analysis of the brain wave signal and the bio signal from the first controller. Then, the second controller determines at least one of a degree of engagement and an emotional reaction of the subject to the content, using changes in the brainwave signal and the bio signal, and evaluates the content using the determined results.
