The present disclosure relates to methods and devices for identifying an action. In some embodiments, a method for identifying an action includes: recording vibration trajectory information, wherein the vibration trajectory information corresponds to vibration of at least a portion of an intelligent device from a start of a vibration event to stabilization of the vibration event; determining whether the vibration is a damping vibration based on the vibration trajectory information; and in response to determining that the vibration is a damping vibration, determining that the vibration is caused by a user's trigger action, or in response to determining that the vibration is not a damping vibration, determining that the vibration is not caused by the user's trigger action.
