1. A navigation device applied to wireless identification tags, comprising:
a movable signal transceiver adapted to transmit a detection signal and receive an actuation signal generated by the detection signal from the wireless identification tags; and
an operation processor electrically connected to the movable signal transceiver, the operation processor being adapted to analyze the actuation signal to acquire relative position between the wireless identification tags, and set an accessible area and a prohibited area in response to the relative position so as to generate a motion parameter for moving the movable signal transceiver within the accessible area instead of the prohibited area.
