1. A wearable device comprising:
a first sensor configured to sense first data;
a second sensor configured to sense second data, an energy utilization of the first sensor being less than an energy utilization of the second sensor; and
a processor configured to:
perform a comparison between the first data and a first threshold value,
if the comparison passes the first threshold value, perform a comparison between the first data and a second threshold value,
if the comparison passes the second threshold value, cause the second sensor to sense the second data and process the second data, and
if the comparison fails the first threshold value or the comparison fails the second threshold value, cause the second sensor not to sense the second data.
