Most of the people make presentations by using tools such as pointers. However, the use of information devices such as PCs and mice restrict the presenter's embodied motions and actions. In this paper, we propose a presentation support system PPTouch that can expand embodiment in presentation by using a portable touch screen device. First, we develop a prototype of the system by using an iPhone. Next, we perform the experiment to compare with conventional pointers by presenters. After that, we also perform the evaluation by participants. Both experiments show the effectiveness of PPTouch. Finally, we add functions for presentation, and publish PPTouch on Apple App Store for free.
