Abstract: An object searching method is disclosed. The object searching method includes the following operations: receiving an user message; analyzing an object name from the user message; obtaining a locator corresponding to the object name according to a locator mapping table; detecting a locator distance and a locator direction of the locator; generating a description string according to the locator distance, the locator direction, and a feature direction map; generating a voice message according to the description string and the object name; and broadcasting the voice message.

Abstract: A positioning system includes a radio frequency (RF) device, a microphone array, and a calculation device. The RF device is configured to transmit an RF signal to an external device for pairing with the external device. The microphone array is configured to receive an audio signal transmitted from the external device after the positioning system is paired with the external device. The calculation device is configured to calculate a direction from the positioning device to the external device based on a time interval of the audio signal received by the microphone array, and configured to calculate a distance between the positioning system and the external device based on the audio signal transmitted by the external device after pairing. The calculation device is configured to position a location of the external device according to the direction and the distance.
