Design of a low cost interactive digital signage

Abstract

In this paper, we propose an Interactive Digital Signage (IDS) which consists of three parts: passive infrared sensor (PIR), ultrasonic sensors and an embedded system. Our system uses the Newton-Raphson method to acquire the hand moving directions and distances, which were transferred to relative command to control the system. Compared with other interactive devices, we use low cost sensors instead of cameras to approach the audience motion capture. Therefore, the IDS not only supports interaction ability but also decreases hardware and software cost to implement it.

Design and implementation of mobile traffic warning triangle

“…The system measure the distance between user and interactive digital signage with the infrared and ultrasonic signals. They use the Newton-Raphson method accurate to find the coordinate in the space [3]. The other research use ultrasonic module to detect hand position in the space becomes the hand gesture based television control [4].…”
