Portable Audience Metering with Beacon Ping Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audience monitoring systems face challenges in accurately identifying which media a person is exposed to due to interference from multiple audio sources and the difficulty in determining proximity to media devices, leading to potential over-representation and illogical behavior in data collection.
Innovation Solution
The system employs portable metering devices and ping beacons to determine proximity to media devices by transmitting and receiving ping signals, analyzing audio signals, and using power levels and distance values to correlate the media exposure, eliminating the need for stationary devices and reducing manipulation of ratings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable metering devices are used to monitor audience exposure, then mobility and flexibility are improved, but measurement precision deteriorates due to interference from multiple audio sources and difficulty in determining proximity to media devices
Solution Approach 1:
The patent introduces beacons as intermediary devices placed near media devices to mediate between the portable metering device and the media source. The beacons transmit signals that enable the portable device to determine proximity and correlate audio exposure with specific media devices, resolving the precision problem while maintaining mobility
Solution Approach 2:
The patent replaces traditional stationary mechanical metering devices with portable electronic devices that use signal processing and wireless communication. This substitution enables mobility while using electronic signal analysis (ping signals, audio fingerprinting) to achieve accurate measurement despite multiple audio sources
2Measurement precision
If traditional stationary metering devices are used, then measurement precision is maintained, but device complexity and installation difficulty increase
Solution Approach 1:
The patent segments the measurement system into separate functional components: portable metering devices for audience monitoring, beacons for proximity indication, and audio fingerprinting capabilities for media identification. This segmentation reduces the complexity of any single device while maintaining overall system precision
Solution Approach 2:
The portable metering device performs multiple functions: detecting audio signals, determining proximity via beacon signals, identifying media through audio fingerprinting, and transmitting data. This multi-functionality eliminates the need for separate stationary devices, reducing overall system complexity while maintaining measurement precision
