This paper describes the development of a tangible puppetry role-play simulation system called “EduceBoard”, which enables students to role-play, based on various character’s voices, in role-play simulation. It is to be noted that students are unable to play the diverse roles of children due to psychological inhibition and other factors in face-to-face self-performed role-play. EduceBoard is a tangible puppetry role-play simulation system that assists improvisational role-play, such as microteaching, by enabling students to play using puppets. It also provides web animation and comment functions for reflecting upon their play, recorded in a server. This paper describes the design specifications and implementation of the EduceBoard system, and discusses the current and future system applications.
