Information processing apparatus and information processing method, and robot apparatus

An information processing method for performing processing related to a device configured to autonomously behave to an object identified by an identifier, the information processing method comprising:

• acquiring a state of the identifier;
• deciding a behavior of the device on a basis of the state;
• determining a decline in identification performance for the identifier identifying a user;
• and
• deciding a behavior of the device for identifying a cause for a decline in identification performance, and controlling the identifier to handle data newly acquired from a user along with a decline in the identification performance,
• wherein, in a case where it is identified that the cause is attributed to a temporary change of the user, controlling the identifier to use newly-acquired data only temporarily.

A robot apparatus comprising:

• a sensor;
• a driver;
• circuitry configured to:
• identify an object on a basis of an output of the sensor;
• decide a behavior that uses the driver, on a basis of a state of the circuitry;
• determine a decline in identification performance for the sensor identifying a user;
• and
• decide a behavior of the robot apparatus for identifying a cause for a decline in identification performance, and control the sensor to handle data newly acquired from a user along with a decline in the identification performance,
• wherein, in a case where the circuitry identifies that the cause is attributed to a temporary change of the user, the circuitry controls the identifier to use newly-acquired data only temporarily.
