Digital Signage has been evolved continuously over the years, and it has shown the potential in application of navigation recently. Comparing to conventional usage of advertisement and broadcasting, the interacting with digital signage has gained great interest for researchers due to hot issue of Internet of Thing. In these days, the ubiquity of smartphone and the development of sensor make it possible to apply more intuitive interaction with digital signage. A new navigation system which combined UHD (Ultra High Definition) display with personal smartphone is proposed. User is allowed to control Web-based 3D model instead of 2D subway map through smartphone's gyroscope sensor. In this paper, multi user access approach is proposed by applying multi subscreen in UHD Signage system with BLE (Bluetooth Low Energy) tech and a novel WebSocket server design. Different from one-to-one control, this approach provides multi-to-multi accessibility that allows multiple users to access the navigation system simultaneously. A novel WebSocket server design reduces the delay and provides better control experience for multiple users' accession. This technology makes user able to access system sequentially, according to the access time and the distance between user and signage. The distance information is provided by iBeacon which attached to the UHD display. The result shows better feasibility when applied this navigation system to solve wayfinding problem inside complex subway station.
