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 30):
A non-transitory computer-readable storage medium tangibly encoded with computer-executable instructions, that when executed by a computing device, perform a method comprising:\n receiving, at the computing device, Bluetooth Low Energy (BLE) signals emitted from devices; analyzing, via the computing device, said received BLE signals, and based on said analysis, determining that said devices are concurrently present at a location; further analyzing, via the computing device, said received BLE signals, and based on said further analysis, determining a BLE signal strength associated with each device at the location, said BLE signal strength, for each device, providing an indication of a distance and a position relative to the computing device; determining, via the computing device, a three-dimensional (3D) spatial mapping of said location based on, for each emitting device, the BLE signal strength, said 3D spatial mapping comprising displayable identifiers and positional information of each device within said location; displaying, via the computing device, said 3D spatial mapping within a user interface (UI) displayed on a display of the computing device, said display of the 3D spatial mapping enabling interaction with the displayed identifiers of each device; receiving, at the computing device, via the displayed UI, a selection of a device identifier displayed within said 3D spatial mapping, said selection enabling communication with a device associated with the selected device identifier; and communicating, via the computing device, data from said computing device to said device associated with the selected device identifier, said communication occurring via a BLE signal packet communicated from the computing device to said selected device.
