Abstract:
One embodiment of the present invention comprises a method of determining a mobile computing device location. The method may comprise emitting at least one audio signal from at least one audio signal emitter and determining a sending time of the at least one audio signal. The method further comprises receiving the at least one audio signal at the mobile computing device and determining a receiving time of the at least one audio signal. A difference between the receiving time and the sending time is calculated and this difference is used to determine a distance from the at least one audio signal emitter to the mobile computing device. The distance is then used to obtain a location of the mobile computing device.
