Open radio map based indoor navigation system

In this presentation, we introduce an open radio map based indoor navigation system. The system is implemented on a Google android phone and tested on 3rd floor, Main-building, KAIST Munji Campus, Korea. The open radio map for the system is constructed by partly participatory approach. That is, the radio map data for rooms and laboratories are collected by ordinary users of smart phones, and for corridors by trained experts. We confirmed that the open radio map based indoor navigation service has a high potential to be used in real fields if the open radio map accumulates sufficient amount of Wi-Fi fingerprints.
