Abstract: A system for determining a location of a device includes at least two speakers and the device, where each speaker is configured to produce a unique sound. The device includes microphones for receiving sound and for providing signals corresponding thereto, a memory configured to store for each speaker a fingerprint of each unique sound and speaker location information, and a processor connected to the outputs. The processor is configured to determine, by comparing microphone signals to fingerprints, a difference in arrival time of a sound at two microphones, and determine, based on the differences in arrival time, an orientation of the device with respect to the speakers, and to determine the location of the device in the space.
