Claim 0:
1. A device for motion sickness reduction associated with physical movement, comprising:
an annular-shaped headband configured to be worn about a horizontal circumference of a human head, the headband having a circumference and comprising:
a plurality of transducers arranged about the circumference of the headband, each transducer being configured to provide haptic feedback to a wearer of the headband; and
a first sensor configured to periodically measure motion of the headband;
a controller comprising a processor, a memory, and a plurality of programming instructions stored in the memory which, when operating on the processor, cause the controller to:
receive motion data from the first sensor, the motion data indicating the direction and the magnitude of the motion of the headband;
receive data pertaining to motion of an external reference frame from a second sensor;
determine a differential motion between the headband and the motion of the external reference frame;
identify a first transducer of the plurality of transducers that is closest in direction to the direction of the differential motion;
operate 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, operate a plurality of additional transducers on 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 difference in differential motion is below the threshold value, cease 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.
