Development of a Tangible Learning System that Supports Role-Play Simulation and Reflection by Playing Puppet Shows

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.

Design of shadows on the OHP metaphor-based presentation interface which visualizes a presenter's actions

We describe the design of shadows of an overhead projector (OHP). metaphor-based presentation interface that visualizes a presenters action. Our interface work with graphics tablet devices. It superimposes a pen-shaped shadow based on position, altitude and azimuth of a pen. A presenter can easily point the slide with the shadow. Moreover, an audience can observe the presenters actions by the shadow. We performed two presentations using a prototype system and gather feedback from them. We decided on the design of the shadows on the basis of the feedback.
