Outline of Final Research Achievements

This research is for the development of infrastructure enabling indoor navigation system for smartphones. Localization for smartphones is carried out using high frequency audio sounds. For time measurement of sound time-of-flight we used phase accordance method, which was developed also in this research group. The localization accuracy is achieved around 10mm using smartphones. In this research we first tested TDoA (Time Difference of Arrival) method, however, the accuracy was under the desirable level. So we added time synchronization mechanism with LEDs, which send sound submission timing to a smartphone's movie camera. With this scheme enables us to adopt accurate ToA (Time of Arrival) measurements the 3D measurement accuracy was achieved around 10mm.The developed infrastructure equipment of indoor navigation system is integrated as lighting facility of buildings.
