1. A hand tracking device, comprising:
a storage circuit, storing a program code; and
a processor, coupled to the storage circuit and accessing the program code to execute:
receiving sensor data from a sensor, wherein the sensor is placed close to an object;
obtaining a hand motion curve of a hand during a period of time;
determining whether the object is moving away from the sensor based on the sensor data;
obtaining an object motion curve of the object during the period of time; and
in response to the object being moving away from the sensor, determining whether the hand is holding the object based on the hand motion curve and the object motion curve.
