3D Simulator of a Rolling Baton on Cylindrical Surfaces
Summary form only given. We make physical analysis of a baton rolling on cylindrical surfaces and then present a 3D simulator which helps us design actual surfaces to be used for a physical performance and for an interactive entertainment system.
Stick'n Roll: A Playful Stick Interface for Curved Display
We present a projection system called Stick'n Roll in which users manipulate a set of sticks (or batons) on a series of curved display. The system relies on the use of unique movement of sticks rolling on convex surfaces. We regard the touching of sticks to the surfaces as input to the display that also functions as a multi-touch input device. We develop a variety of applications such as balloon popping, a music game, a virtual keyboard, and a draw tool that make effective use of the rolling of this stick interface. Since the silhouette of the pair of surfaces resembles a huge opened "picture book", we put some applications together in that virtual book and enabled transferring from one application to the other by turning over the virtual pages. Then, the new experience users can have when they control the sticks and manage the world in the picture book is what we want to share as "kiddy dream in VR", the theme of ReVolution 2015.
The Helen of Geometry
Summary The cycloid has been called the Helen of Geometry, not only because of its beautiful properties but also because of the quarrels it provoked between famous mathematicians of the 17th century. This article surveys the history of the cycloid and its importance in the development of the calculus.
