In this paper, we describe a system that allows a user to read information personally in public spaces without wearing any hardware devices. This paper presents the interface system ”InfoSnow”, which displays information on the palm of the user’s hand. This interface employs a snow fall metaphor to induce the user’s action to catch snowflakes of information, so that information display is focused on the user.
