2. OUTLINES

3. INTRODUCTION
 Inspired by science fiction movies such as Star Wars, two
Finnish virtual reality researchers created the FogScreen to
recreate some of the effects from these movies in real life.
 FogScreen is an exciting new projection technology that
allows to project images and video onto a screen of “dry”
fog, creating the illusion that the images are floating in
midair

4. Brief History
 It was invented by two Finnish virtual reality
researchers
 FogScreen, which was initially known as WAVE (Walk-
Through Virtual Environment), was announced in
December 2001.
 The first public demonstration of FogScreen was in
Finland in October 2002.
 Till then it is in use in different areas and
improvements are being done to increase its
effectiveness.

5. Existing Projecting Devices

6. What is a FogScreen?
 It is one type of advanced projecting device which
consumes water and electricity to form fogs on which
images are projected.
 Here the tea-pot is projected on fog generated by a fog
generating device.

7. Formation of fog screen
• It is formed by using ordinary tap water and digital
technology like ultrasonic device to create a thin layer
of dry fog which is sandwiched between two
air-curtains.
• The fog is created by suspended fog generating device.
• The fog is made up of ordinary tap water with no
chemicals
• FogScreen creates a “dry” fog by ensuring that the
water droplets are in the range of 2-3 microns in size
and are electrostatically charged so that they move
around and away from other objects.

9. How fog machine works?
 FogScreen technology is a high-tech version of the
technology in a cool air humidifier.
 Tap water is pumped into the fog tank where it is blasted
with ultrasound, turning it instantly into a thick fog made
of tiny water particles 2-3 microns in diameter.
 The tank’s internal design plus 3 sets of fans work together
to create a very thin wall of mist about half of an inch thick.
One set of fans blows the fog downwards while the other
two sandwiches the fog between air curtains so that it
becomes a smooth projection screen.

10. How it works…..!!

11. Application
 FogScreen has been used in live malls, product
launches, museums, to attract more and more peoples.
 It is used in case of projection a 3D image esp. in
studies.
 It can be used in seminars to make it more
interactive(we can walk through the screen).
 It can be used in place of air curtain in clubs to make it
more attractive.

12. Application cont…
 Entertain your guests with FogScreen
Whether you are planning a rock concert, a prize ceremony,
an anniversary, any commercial or private event, elevate the
atmosphere with the magical FogScreen. Guests can enter
through the screen to an event!
 Create a luxurious interior with FogScreen
 Mixed reality and immersive projection technology
could use CAVE-like virtual rooms with fog walls, making
them effectively “virtual virtual rooms”.

13. A walk through screen……
The person is standing in between the screen and is absolute DRY

14. Advantages
 A consumer could be enticed to walk through the
FogScreen into a special sales area, for example. The
FogScreen developers say the unique nature of
FogScreen will make it a memorable experience for
customers
 FogScreen is environmentally friendly, as it uses only
water as requirment and produces chemical free fog.

15. Limitations
 Fog Screen works best indoors with a dark background
that enhances the brightness of the image on the Fog
Screen behind the projector. So, it can’t be used in day
light.
 The surrounding should be clam, as breeze can affect
the fog stream
 Its is presently very much expensive, but the
FogScreen.inc is working on providing it in a
reasonable price.

16. Opportunities
 There are endless opportunities to use the products,
but for now these have been mostly innovative
marketing solutions and different exhibitions.
 Stream of fog can appear and disappear within a
fraction of a second, making it a possibility for use in a
live theatre setting to aid with special effects
 Presently it is in demands in countries like Japan,
Malaysia, Germany, France, Greece, Russia, the UK
and the USA, in recent future it will replace the
existing method of projection.

17. Opportunities
 Developments are being carried out in making
FogScreen a Touch-FogScreen to make it more
interactive for the viewer.

18. Success of FogScreen
 FogScreen has been successfully used in this international
events:
1. Entertainment (live shows, live concerts, night clubs,
stage productions, private parties ie. Disney Enchanted
Tour, Eurovision, Harrah’s, Cirque de Soleil, MGM Grand,
20th Century Fox)
2. Brand promotions (P&G, Diesel, Victoria’s Secret. Bud
light/Maxim Tour, Xbox)
3. Trade shows and exhibition events (Nokia, Motorola,
Sony, Siemens)
4. Theme parks (Key US theme parks)
5. Museums and Science Centres (Palais de la Découverte,
Taiwan National Museum)
