Information processing apparatus, mobile object, control method thereof, and storage medium

A method of controlling an information processing apparatus, the method comprising:

• acquiring, from a communication device of a user, utterance information by the user and position information of the communication device;
• specifying a predetermined region according to a mark included in the utterance information;
• acquiring a movement direction of the user from the utterance information and the position information acquired from the communication device of the user, dividing the predetermined region to a plurality of regions based on the acquired movement direction of the user, and setting a probability distribution including probabilities that the user exists to each of the plurality of regions;
• and
• presuming the user based on the set probability distribution.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute each step of a method of controlling an information processing apparatus:

• acquiring, from a communication device of a user, utterance information by the user and position information of the communication device;
• specifying a predetermined region according to a mark included in the utterance information;
• acquiring a movement direction of the user from the utterance information and the position information acquired from the communication device of the user, to dividing the predetermined region to a plurality of regions based on the acquired movement direction of the user, and setting a probability distribution including probabilities that the user exists to each of the plurality of regions;
• and
• presuming the user based on the set probability distribution.

A mobile object comprising:

• a communication unit configured to communicate with a communication device of a user;
• an imaging unit configured to image a surrounding portion of the mobile object;
• a storage device that stores instructions;
• and
• at least one processor that executes the instructions to:
• acquire, from the communication device of the user and by the communication unit, utterance information by the user and position information of the communication device;
• specify a predetermined region according to a mark included in the utterance information;
• acquire a movement direction of the user from the utterance information and the position information acquired from the communication device of the user, divide the predetermined region to a plurality of regions based on the acquired movement direction of the user, and set a probability distribution including probabilities that the user exists to each of the plurality of regions;
• and
• presume the user based on the set probability distribution.

A method of controlling a mobile object including a communication unit configured to communicate with a communication device of a user and an imaging unit configured to image a surrounding portion of the mobile object, the method comprising:

• acquiring, from the communication device of the user and by the communication unit, utterance information by the user and position information of the communication device;
• specifying a predetermined region according to a mark included in the utterance information;
• acquiring a movement direction of the user from the utterance information and the position information acquired from the communication device of the user, to dividing the predetermined region to a plurality of regions based on the acquired movement direction of the user, and setting a probability distribution including probabilities that the user exists to each of the plurality of regions;
• and
• presuming the user based on the set probability distribution.
