Patent Images
1. A method for tracking motion using an audio compass, the method comprising:
- receiving motion sensor data indicating seismic activity recorded by at least two seismic sensors;
converting the received motion sensor data into audio signals for interpretation at an audio compass;
determining a current distance to the seismic activity based on an interpreted signal intensity of the audio signals; and
identifying a current position of the audio compass relative to the seismic activity.

Abstract
A method for tracking motion using an audio compass is disclosed. The method comprises receiving motion sensor data indicating seismic activity recorded by at least two seismic sensors, and converting the received motion sensor data into audio signals for interpretation at an audio compass. The method uses the audio compass to determine a current distance to the seismic activity based on an interpreted signal intensity of the audio signals. The method further uses the audio compass to identify a current position of the audio compass relative to the seismic activity.
