1. A method comprising:
determining, by a device orientation engine executed by one or more processors, a movement between each electrode group of a plurality of electrodes of a catheter to provide a plurality of movements, each electrode group comprising at least two adjacent electrodes;
determining, by the device orientation engine, a total movement of the plurality of electrodes;
removing, by the device orientation engine, a standard component from the plurality of movements and the total movement after the plurality of movements are determined, the standard component comprising respiration movement and heartbeat movement; and
outputting, by the device orientation engine, a movement indication for the catheter based on the plurality of movements and the total movement with the standard component removed.
