In this paper, we propose new robotics presentation method called, Self Introducing Poster that uses attachable humanoid parts and explains its contents through a self introduction style. Presentation by a conventional robot sometimes fails because the robot presenter is often too attractive and distracts from the presentation itself. In our method, the poster is anthropomorphized and explains its contents. Due to this self presentation, users can more easily understand its meaning because the information's contents and information provider are strongly related. We designed and implemented our system and evaluated it in the field. The results suggest that the self-introducing system is useful for gaining users attention and effectively presenting information.Copyright is held by the author/owner(s).
