A Presentation Support System by Expanding Embodiment with a Mobile Touchscreen Device

Abstract — Most of the people make presentations by using tools such as pointers. However, the use of information devices such as laser pointers and mice can restrict the presenter’s embodied motions and actions. In this paper, we propose a presentation support system that can expand embodiment by using a portable touch screen device. First, we develop a prototype of the system by using an iPhone, and then, we perform experimental evaluation. Next, we performe the evaluation of the modes of PPTouch, and the effectiveness of the system in various situations is clarified. Then we performe comparison with conventional pointers, and evaluation by participants. Both experiments also show the effectives of PPTouch. Keywords- presentation support; expansion of embodimen
