Development of Educational System with the Android Robot SAYA and Evaluation

This chapter describes an educational system with a tele‐operated android robot, named SAYA, that can express human‐like facial expressions and perform some communicative functions with its head and eye movements, and it is utilized as a role of a teacher. Two kinds of field experiments were conducted to investigate effectiveness of this educational system in actual educational fields. An experiment was conducted at both an elementary school and a university to estimate age‐ dependent differences of its effectiveness. The other experiment was carried out to verify whether children's interest, motivation, and concentration to the class, and science and technologies were enhanced.
