Abstract

We describe the design of shadows of an overhead projector (OHP). metaphor-based presentation interface that visualizes a presenter's 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 presenter's 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.
