Claim 6:
7. A method for motion sickness reduction associated with physical movement, comprising the steps of:
periodically receiving, at a controller, motion data from a first and a second sensor, the motion data from the first sensor indicating a direction and a magnitude of motion of a headband comprising a plurality of transducers and the motion data from the second sensor indicating a direction and a magnitude of motion of an external reference frame;
determining a differential motion between the external reference frame and the headband;
identifying a first transducer of the plurality of transducers that is closest in direction to the direction of the differential motion;
operating the first transducer, the intensity of transducer operation corresponding to the magnitude of the differential motion;
while the magnitude of the differential motion meets or exceeds a threshold value, operating a plurality of additional transducers to either side of the first transducer, the intensity of operation of the plurality of additional transducers corresponding to the magnitude of the differential motion, but at a lower intensity than the operation of the first transducer;
while the magnitude of the differential motion falls below the threshold value, ceasing the operation of the plurality of additional transducers; and
repeating the operations of the controller set forth above as the differential motion data is recomputed as new data is received from the sensors.
