3. INTRODUCTION
 Fog Screen 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.
 The Fog Screen is an innovative display
Technology that allows for projections on a
thin layer of dry fog.

4. Breif History
 Fog Screen, which was initially known as WAVE
(Walk-Through Virtual Environment), It 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. What is Fog Screen
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.

6. Formation of Fog Screen
 Fog screen 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.

9. Advantages
 The Fog Screen developers say the unique nature
of Fog Screen will make it a memorable experience
for customers.
 Fog Screen is environmentally friendly and uses
only water as requirement and produces chemical
free fog.
 Increase production skills-technology transfer.
Increase quality of product -enter to new market.
(In different market.)

10. Disadvantages
 Projections can be obscured.
 Storage space.
 Sizing issues and setup.
 Damage the screen.
 Health Dangers.

11. 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 daylight.
 Need 1kW of energy to produce 1m long fog
screen.
 And it is produce 3-5 litres of water in one hour
which should be vent. And you can't make a high
fog screen, because fog would diffuse with
distance.

12. Applications
 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.

13. Opportunities
 There are endless opportunities to use the
products, but for now these have been mostly
innovative marketing solutions and different
exhibitions.
 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.

14. Conclusion
 Technology of the future literally revolutionizes
the limits of projection screens and blurs the
boundaries among art, science, and fun.
