Campus Digital Signage: Connection of Correlated Information between Distributor and Receiver

Information distribution regarding immediately correlated contents is a big challenge in local communities, such as a university campus. One of the main reasons is that a campus' local network is uncovered by public search engines, and most of the local Web sites in a community operate like information silos. A secondary reason is that the daily activities in a local community are highly dynamic, people might be annoyed by the non-correlated information or they just ignore all of it, regardless of importance. In this paper, the proposed campus digital signage aims at connecting local users to correlated information as the user passes by. To this end, we build the server side with two components, one is the information collector that will automatically pull the campus information from other sites, and the other is the information poster to allow qualified users to post content. We also design a wearable client side with a BLE (Bluetooth low energy) proximity sensor to recognize approaching user's identity and dynamically push their correlated information to the digital signage display.
