<p>An apparatus and a method in an electronic device to determine a position of the first electronic device relative to a plurality of other electronic devices is disclosed. The method includes the first electronic device transmitting a first vibration signal from the first electronic device. The first electronic device receives vibration signals from other electronic devices. The first device determines a first plurality of signal strengths from the vibration signals. The first electronic device receives a second plurality of signal strengths via wireless communication link from the other electronic devices, wherein the second plurality of signal strengths includes signal strengths associated with the first vibration signal and signal strengths associated with the vibration signals received from the other electronic devices. The first electronic device calculates planar coordinates of the electronic devices based on the first and second signal strengths.</p> |
