1. A system, comprising:
at least one storage device configured to store computer instructions; and
at least one processor in communication with the storage device, wherein when executing the computer instructions, the at least one processor is configured to direct the system to perform operations including:
obtaining a sensing signal of at least one sensing device, the at least one sensing device including a vibration sensing device and an audio input device, the vibration sensing device being arranged on a wearable device, the wearable device being attached to a body part of a user, and the vibration sensing device receiving the sensing signal that is a vibration signal generated by a body activity of the user through the wearable device;
determine whether the audio input device simultaneously receives user audio information when the vibration sensing device receives the sensing signal; and
in response to a determination that the audio input device receives user audio information, designating the sensing signal as a false trigger signal;
in response to a determination that the audio input device does not receive user audio information,
identifying a signal feature of the sensing signal; and
determining, based on the signal feature, an operation of a target object associated with the at least one sensing device.
