Developmental learning model for joint attention

This paper proposes a developmental learning model for joint attention between a robot and a human care-giver. The proposed model has abilities to acceler-ate the learning and improve the final task perfor-mance owing to two kinds of developments: a robot’s development and a caregiver’s one. The robot’s de-velopment means that the sensing and the actuating capabilities of the robot change from immaturity to maturity. On the other hand, the caregiver’s devel-opment is defined as that the caregiver changes the task from easy situation to difficult one. The pro-posed model causes these developments according to the learning progress of the robot. The experimental results showed what kinds of effects the developments bring to the learning.
