Crowd Monitoring of Expo

Abstract

To solve those problems, we introduce a system that provide, collect information about visitors’ trends at exhibition. The system includes numbers of beancons, some mobile devices and an web application. We use beacon combined with mobile application to determise the position of the visitors in the exhibition. We collect all user location information to generate the heat map. Depend on the user location and infomation about stalls, we will give the suggestions for visitors.However, at starting point, there is some problem for developing the system. The SDK of Estimote Beacon is strange with our team members, so we need alots time to research new technology. There are two kinds of beacon: Estimote Location Beacon and Estimote Proximity Beacon. Location Beacon can provide exact location of device. Beside that, Proximity Beacon only provide the relative position of device within signal range of the beacon. However, the Location Beacon is more expensive than Proximity Beacon. So, we have had difficulty choosing type of beacon. Following to Estimote Beacon document, “do not expect distance estimations from beacons”. So the team must study the new way about idetify the distance between smartphone and Estimote Beacon. Following to Estimote Beacon document, it categorizes the Beacon into four proximity zones: Immediate (strong signal; usually up to a few centimeters), near (medium signal, usually up to a few meters), unknown (“hard to say”, usually when the signal is very, very weak). They do not provide us the exactly proximity zones in number. Therefore, our team must test to determine the exactly number.
