Signage Device Face Detection for Targeted Audio Ads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advertising systems in public areas only provide visual advertisements, lacking auditory components and potentially disturbing non-interested pedestrians when audio is played at higher volumes, failing to identify and engage only interested individuals.
Innovation Solution
An advertising system that uses face detection through a camera module on signage devices to connect with user devices, such as wireless headphones, to deliver audio advertisements only to interested individuals, employing ultrasound or infrared transmission for convenience and power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If advertisement audio is played at larger volume, then advertisement pushing in sense of auditory is improved, but disturbance to pedestrians who are not interested is increased
Solution Approach 1:
The patent applies local quality by directing audio advertisement transmission selectively to specific user devices (those with detected interested users) rather than broadcasting to all areas. The audio output is localized to individuals who have been identified as interested through face detection, while non-interested pedestrians receive no audio output, thus eliminating disturbance to them.
Solution Approach 2:
The patent introduces user devices (such as smartphones or wearable devices) as intermediaries between the advertisement system and pedestrians. These intermediary devices receive and play audio advertisements only for users who have been identified as interested, acting as a bridge that delivers auditory information selectively without causing disturbance to the surrounding environment.
2Adaptability or versatility
If face detection and user identification functions are added, then targeted advertisement delivery is improved, but device complexity is increased
Solution Approach 1:
The patent applies universality by utilizing existing camera modules and processing units that are already present in modern signage devices for multiple purposes: both for general display operations and for face detection and user identification. This multi-functionality approach enables targeted advertisement delivery without requiring completely separate dedicated hardware systems.
Solution Approach 2:
The patent implements self-service by leveraging the computational capabilities already embedded in the signage device itself to perform face detection and user identification. The system uses its own existing processing resources and camera hardware to automatically identify interested users and trigger targeted audio delivery, eliminating the need for external separate identification systems.
