Abstract.
In this paper, we propose the method for creating multi-view mova-
ble fogscreen, and then implement it in our system called “HANASUI”.
“HANASUI” displays handheld-like fireworks through a fog screen instead of
sparkles. Our method generates projection data dynamically from a virtual
space and then casts it with multiple projectors, tracking the marker attached to
the device which spouts fog at the fogscreen with infrared cameras and infrared
floodlights. Finally, we conducted a survey to verify the capabilities of
“HANASUI” and its potential for art and entertainment purposes.

Introduction
A fogscreen, which uses fog as a projector screen, has proposed as a technological
system for event staging or information presentation [1,2]. A feature of the fogscreen
is that, unlike conventional displays that have used liquid crystal, it doesn't have a
clearly defined edge or the edge is subtle. Another feature is that, because the screen
is made of fog, the projected image can be touched. These points are factors that give
image a great degree of freedom as well as three-dimensionality. Rakkolainen et al.
have constructed an interactive system that applies this characteristic of being able to
directly touch the image, and have identified its potential for use in entertainment and
the arts [1,2]. Furthermore, recent years have seen the commercialization of the fog
screen that can be used in the same way as a touch screen [4], and it is expected that
in future they will become a more familiar sight.
However because a feature of the fogscreen is that light rays are more widely scat-
tered due to the effect of Mie scattering users can only view an image from within a
small range of distance from the fog and on the opposite side to the projector [5].
