Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring media data exposure lack accuracy in linking individual users to media data, often resulting in inconsistencies and inaccuracies in aggregate user exposure tracking.
Innovation Solution
The use of inductive coupling technology to verify and associate media data exposure with portable computing devices, generating research data by detecting and communicating information through inductive connections between devices, such as computers, radios, and televisions, to produce accurate media exposure reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aggregate numbers are used to determine total user exposure to media data, then productivity is improved, but measurement precision deteriorates
Solution Approach 1:
The system segments the measurement process into two levels: aggregate exposure tracking for overall statistics and individual device verification through inductive coupling for precise user identification. This segmentation allows the system to maintain both high productivity in aggregate tracking and high measurement precision in individual user verification.
Solution Approach 2:
The patent introduces portable computing devices with inductive coupling capability as intermediaries between media devices and the verification system. These intermediary devices detect inductive coupling signals to verify user presence and link individual users to media data consumption, thereby improving measurement precision without compromising aggregate tracking efficiency.
2Measurement precision
If inductive coupling technology is used to verify media data exposure with portable computing devices, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent makes portable computing devices perform multiple functions: they serve as both media consumption devices and verification devices through inductive coupling capability. This multi-functionality reduces the need for separate verification hardware, thereby limiting the increase in overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The system uses the portable computing device's own inductive coupling capability to verify its presence and link to media data. The device essentially verifies itself through the inductive coupling mechanism, reducing the need for external verification infrastructure and limiting complexity increases.
