Abstract
A method, a wearable device, and an apparatus for monitoring sleep of a user are provided. The method includes: determining an activity amount of a user based on multi-axial acceleration data received by the wearable device in a time period, in which the multi-axial acceleration data includes acceleration data in multiple axes; if the activity amount is smaller than a first threshold, determining a microactivity feature value using the multi-axial acceleration data and predetermined weights; and determining a microactivity state for the user in the time period based on the microactivity feature value, in which the activity amount of the user is substantially zero in the microactivity state.
