Indoor positioning method for augmented audio reality navigation systems using iBeacons

We studied the feasibility of the use of iBeacons for position detection in indoor navigation systems. We initially used four iBeacons located at corners of a room, and compiled a database of the radio wave strength from these. Then we matched the detected strength at an unknown location to the database to estimate the current position. The overall average accuracy was 0.8 m. This accuracy should be enough for our system using augmented audio reality, to be implemented in the future. However, we would like to test the effect of increasing the number of iBeacons for improved accuracy as well.
