Claim 8:
9. A method for detecting eye movement, comprising:
at a device including sensing circuitry and a processor:
sensing a physiological signal from a plurality of electrodes, the physiological signal associated with the eye movement;

in accordance with the physiological signal meeting one or more first criteria indicative of a first level of eye movement, operating the sensing circuitry in a first power level mode of operation to sense the physiological signal from the plurality of electrodes;
in accordance with the physiological signal meeting one or more second criteria indicative of a second level of eye movement, operating the sensing circuitry in a second power level mode of operation to sense the physiological signal from the plurality of electrodes, the second power level mode of operation different than the first power level mode of operation; and
while operating the sensing circuitry in the second power level mode of operation:
in accordance with the physiological signal meeting one or more third criteria, operating the sensing circuitry and the processor in a third mode of operation, the third mode different than the first power level mode of operation and the second power level mode of operation.
