Abstract:
Disclosed is a three-dimensional ad-hoc tracking system and method between two or more devices at a location. The disclosed systems and methods can be implemented on commodity mobile devices with no added components and require no cross-device calibration, in order to track surrounding devices. Such tracking can be achieved by fusing three types of signals: 1) the strength of Bluetooth low energy signals reveals the presence and rough distance between devices; 2) a series of inaudible acoustic signals and the difference in their arrival times produces a set of accurate distances between devices, from which 3D offsets between the devices can be derived; and 3) the integration of dead reckoning from the orientation and acceleration sensors of all devices at a location to refine the estimate and to support quick interactions between devices. The disclosed systems and methods can be implemented by cross-device applications on mobile devices.

Claim (Index 37):
The non-transitory computer-readable storage medium of  claim 30 , wherein said 3D spatial mapping is updated upon a detected change in said positional information of at least one device determined to be at said location, said change detection based on inertia data provided by said at least one device.
