Claim 0:
1. An artificial intelligence (AI) apparatus for determining a path of a user, the AI apparatus comprising:
a communication unit configured to communicate with a plurality of external AI apparatuses; and
a processor configured to:
determine a maximum value of an utterance volume of the user for each of the plurality of external AI apparatuses using sound signals,
set an utterance volume in a distance closest from the external AI apparatus to the maximum value of the utterance volume of the corresponding external AI apparatus,
receive the sound signals of the user from the plurality of external AI apparatuses while the user passes from a first AI apparatus to a second AI apparatus,
calculate a distance and a variation of the distance from each of the plurality of external AI apparatuses to the user based on a volume of the received sound signals and the set utterance volume in a distance closest of the plurality of external apparatuses including the first AI apparatus and the second AI apparatus,
determine candidate areas in which each of the plurality of external AI apparatuses can be disposed based on the distance and the variation of the distance calculated at different times,
determine at least one of locations or relative location relations of the plurality of external AI apparatuses based on the determined candidate areas,
determine a current path of the user using at least one of the locations or the relative location relations based on the calculated distance and the calculated variation of the distance, and
determine a future path of the user based on the current path.
