ROBOT DEVICE, ITS STATE TRANSITION MODEL CONSTRUCTION METHOD AND BEHAVIOR CONTROL METHOD

摘要

PPROBLEM TO BE SOLVED: To control emotion of a user by using an emotional transition model, by further accurately constructing the emotional transition model of the user via the interaction with the user. PSOLUTION: In this robot device, a user voice recognizing part 401 and a user image recognizing part 402 respectively detect the emotion of the user on the basis of a voice signal and an image signal of the user. An emotion estimating part 404 classifies present emotion of the user into any of a plurality of emotions dispersed in advance in the predetermined number on the basis of these detecting results. A long-term storage part 405 stores the emotional transition model of the user constructed by intensifying learning on the basis of the emotion after the user reveals a certain behavior in a certain emotion and remuneration imparted from the user by its transition. A behavior selecting part 406 selects behavior revealed in response to the present emotion of the user as a probability in response to a measure . A behavior output part 407 reveals selected behavior. PCOPYRIGHT: (C)2005,JPO&NCIPI
