Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If physiological signals (EEG, heart rate) are used to measure engagement, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveengagement measurement accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple physiological measurement components (EEG electrodes, heart rate sensors, galvanic skin response detectors) into an integrated system that simultaneously captures multiple engagement indicators. This merging approach improves measurement precision by capturing comprehensive physiological data while managing complexity through integrated architecture.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system is designed to measure multiple types of physiological signals (brain waves, heart rate, skin conductance) using a single integrated platform. This multi-functionality allows the system to capture various aspects of engagement through different physiological channels, improving overall measurement accuracy without requiring separate dedicated devices for each metric.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

AI summary

A system and method for calculating an engagement value by quantifying an amount that a user is acting without thinking considering brainwaves and a heart rate can be used to compare media based on an individual or a group of individuals. Events of the media can be contrasted and compared by the engagement value as well. Statistical measurements may be taken to improve media.
