An Indoor Position System Based on Dynamic Digital Signage and Mobile Devices

GPS has become a significant technology in our daily life and has been the most popular positioning technology on cellular phones(devices). Although it does manage most of wayfinding problems, indoor navigation is difficult without the satellite signals. Wayfinding is even more difficult if users are in a large building with a complicated layout, such as museums and shopping malls. To solve the problem, researchers have proposed varied methods, such as working with sensors or other devices or improve positioning algorithm. This research aims to solve the problem through the collaboration of mobile applications and digital signage while making the performance of digital marketing and information dissemination more effective. The system is based on low-cost wireless communication technologies to build an indoor position and navigation system and a personalized signage service to offer a more accurate position and marketing information on demand.
