Fog screen technology allows images and video to be projected onto a screen of dry fog, creating the illusion that the images are floating in midair. It was initially developed in 2001 and first demonstrated publicly in 2002. Fog screens work by using ultrasonic waves to instantly transform water into a thick fog of small particles, onto which images are projected. They have advantages like being environmentally friendly and providing an engaging experience, but limitations include only working indoors and requiring a dark background to enhance brightness. Fog screens have applications in exhibitions, product launches, and museums to attract audiences.

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.
