FogScreen is break through technology that allows projection of high
quality images in the air. It is currently the only walk-through
projection screen.

Fogscreen003 You can literally use the air as your user interface
by touching only the air with your bare hands. The screen is created by
using a suspended fog generating device with no frame around, and works
with video projectors. The fog they use is dry, so it doesn’t make you
wet even if you stay under the FogScreen device for a long time.  The
fog is made of ordinary water with no chemicals whatsoever. With two
projectors, you can project different images on both sides of the screen.

The FogScreen is a new invention
which makes objects seem to appear and move in thin air! It is a screen
you can walk through! The FogScreen is created by using a suspended fog
generating device, there is no frame around the screen. The
installation is easy: just replace the conventional screen with
FogScreen. You don´t need to change anything else – it works with
standard video projectors.

The world premiere demonstrations of FogScreen was at the Science Fair
in Turku, Finland in October 2002. FogScreen volume production has
started in late 2004. Interactivity add-in was presented in June 2005.

  • FogScreen creates a screen 79" (2 meters) wide and 59" (1,5 meters) high
  • The dimensions of the unit are 25,6" (65cm) high * 35,4" (90cm) deep * 91" (2,31m) wide, weight ~150 kg
  • Needs either water mains connection (long term use) or a water reservoir (short term use)
  • 1-phase 10A/230V or 20A/115V electricity
  • Tariff code: 8424 30 90 00

Interactive LearningInteractivity add-on makes it possible to
write and draw in the air with only your hand using your finger as a
pointer. The set allows you to use your bare hand touching air to
emulate mouse. The interactivity set also includes our proprietary
software enabling you to create fiery characters or fireworks.

All the important principles of FogScreen technology have patent
pending. The basic components of the screen are a laminar,
non-turbulent airflow, and a thin fog screen created this way, the fog
screen is an internal part of the laminar airflow, and remains thin,
crisp, and protected from turbulence.

The fog is made within the device using water and ultrasonic waves. If
you hold your hands in the fog flow, the fog feels dry and cool, and
your hands do not get wet.

After the screen is formed, images can be projected onto it. The screen can be translucent or fully opaque.

The FogScreen works very much like an ordinary screen in terms of
projection properties. FogScreen is best when used for real projection
situations. A projector with at least 3000 ANSI Lumen is recommended.
Distance between projector and screen should be a minimum of 2 meters.

The image is spectacular in normal daylight, but the darker the room,
the better the result. For the best result, a dark background is highly
recommended.

This property is especially utilized in applications operated by the
public, in advertising, in malls for presenting shops and products, in
art productions and events, and as interactive exhibits in museums.

The FogScreen has been featured extensively in scientific, financial,
cultural and other international media, including; CNN, Reuters, Wired
Magazine, Herald Tribune, Discovery Channel and NBC.
