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.
Calculation of and Errors in the Susceptibility
The measurement of the susceptibility requires three measurements, two of which have to be performed with a substance of known susceptibility. The difference of these last two measurements furnishes the proportionality constant of the apparatus, always employing the same volume, while the difference with the unknown substance gives the required susceptibility.
