In-Vehicle Audio Ad Matching for Location-Based Navigation Prompts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-based media systems lack the ability to provide additional information to occupants about audio content, such as advertisements, which may not be encoded with visual information, limiting the user experience and opportunities for interaction with advertised businesses.
Innovation Solution
A vehicle-based media system that captures audio content, identifies reference audio content with similar fingerprints, and uses location data to prompt navigation to associated geographic locations, enhancing user interaction with advertisements by displaying directions to nearby business locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If audio content is received and output through speakers, then the media system provides audio entertainment to occupants, but the system cannot provide additional information about the audio content such as advertisements
Solution Approach 1:
The system captures the audio output from speakers through a microphone, creating a feedback loop that allows the system to analyze what is actually being played. This captured audio is then processed to identify advertisements and extract location information, enabling the system to provide additional relevant information about the audio content.
Solution Approach 2:
The patent introduces an intermediary processing stage between audio output and user interaction. The captured audio content serves as an intermediary that is analyzed to identify advertisements, which then triggers the retrieval and display of location information from a database, bridging the gap between audio content and additional information provision.
2Productivity
If the system captures and analyzes audio content to identify advertisements, then user engagement with advertisements increases, but the system complexity increases
Solution Approach 1:
The system uses its own audio output as the source for identification. By capturing what it itself plays through the speakers, the system eliminates the need for external audio sources or complex synchronization with external media players, simplifying the overall system architecture while maintaining advertisement identification capability.
Solution Approach 2:
The patent combines multiple functions into a unified system: the media player, audio capture device, advertisement identification algorithm, and navigation system work together as an integrated whole. This merging reduces the complexity that would arise from interfacing multiple separate systems while enhancing user engagement through seamless operation.
3Measurement precision
If the system uses microphone to capture output audio content, then the system can identify reference audio content, but the system requires additional hardware components
Solution Approach 1:
The patent replaces the need for complex external audio analysis hardware with a simpler approach using the vehicle's existing microphone and speaker system. Instead of requiring dedicated audio capture and analysis devices, the system uses the existing audio playback infrastructure in reverse, substituting mechanical/audio hardware complexity with software-based audio fingerprinting and pattern recognition.
Data Source
AI summary
In one aspect, an example method to be performed by a vehicle-based media system includes (a) receiving audio content; (b) causing one or more speakers to output the received audio content; (c) using a microphone of the vehicle-based media system to capture the output audio content; (d) identifying reference audio content that has at least a threshold extent of similarity with the captured audio content; (e) identifying a geographic location associated with the identified reference audio content; and (f) based at least on the identified geographic location associated with the identified reference audio content, outputting, via the user interface of the vehicle-based media system, a prompt to navigate to the identified geographic location.
