Digital Signage with Audience Detection Using TV Broadcasting Waves

Abstract

We propose of a digital signage system with a new audience detection system using TV broadcasting waves and show its experimental trial at our university for about three months. For audience motion detection, we use received level fluctuations of TV broadcasting waves by sensing physical movement. The authors have already developed this detection technique and we applied this as audience detection of digital signage. When our detection method detects human motion, a digital signage system will turned on its display. This flow grabs more attention to the signage display and effectiveness of saving electric power. Through the experimental trial, we show that our detection method provides effectiveness for audience detection of digital signage with a big monitor and we can save the electric power of 60-70% of the signage display and one of 94% in business days and in holidays, respectively.
