Solution Overview

Problem

Current methods for assessing participant engagement with content, such as eye-tracking, facial coding, EEG, GSR, and implicit reaction time, are limited by high data loss, inaccuracy, cost, and impracticality for real-world and multi-participant scenarios, failing to accurately measure neurologic responses and predict behavior.

Innovation Solution

A neurologic immersion assessment system that utilizes heart rhythm data collected via photoplethysmography (PPG) sensors, processing this data to provide clean metrics on immersion levels, including attention and emotional resonance, enabling real-time analysis and prediction of experience outcomes for multiple participants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If EEG devices with many electrodes are used to improve measurement precision, then reliability of brain activity detection is improved, but device complexity and ease of operation deteriorate due to cumbersome caps and lab-only usability

Engineering Contradiction:

Improvebrain activity detection accuracyVSAvoidusability in real-world settings

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent extracts the essential function of EEG (brain activity detection) and implements it through alternative means - using wearable PPG sensors to measure peripheral physiological signals (heart rate, pulse variability) that correlate with neural activity. This removes the need for complex electrode caps while maintaining measurement capability in real-world settings.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical/electrical system of EEG electrodes and amplifiers with an optical system (PPG sensors using light absorption to detect blood volume changes). This substitution enables wireless, wearable operation while capturing neurologic engagement data through peripheral circulation patterns that reflect brain activity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If multiple participants are assessed simultaneously to improve productivity, then output per time is improved, but measurement precision deteriorates due to data synchronization and individual variation challenges

Engineering Contradiction:

Improvemulti-participant assessment throughputVSAvoidindividual immersion measurement accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent segments the assessment system into independent wearable sensor units for each participant, with individual data processing pipelines. This allows simultaneous assessment of multiple participants while maintaining precise individual measurement through separate data streams that are processed independently before aggregation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent collects excessive physiological data points (multiple heart rate variables, pulse timing metrics, respiratory patterns) from each participant, then processes this rich dataset to extract precise immersion measurements. The excessive data collection ensures sufficient signal quality even when multiple participants are assessed concurrently.

Inventive Principle:

Principle #16Partial or excessive action

3Ease of operation

If traditional engagement methods like surveys and focus groups are used to improve ease of operation, then participant comfort is improved, but measurement precision and reliability deteriorate due to subjective bias and low accuracy

Engineering Contradiction:

Improveparticipant comfortVSAvoidengagement measurement accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements self-service measurement where the participant's own physiological system serves as the measurement instrument. The wearable sensors automatically collect and process physiological data without requiring participant interpretation or response, eliminating subjective bias while maintaining comfort during natural experience engagement.

Inventive Principle:

Principle #25Self-service
