3. INTR0DUCTION Inspired by science fiction movies such as Star Wars, two Finnish virtual reality researchers created the Fog Screen to recreate some of the effects from these movies in real life.  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

4. Conti… Imagine the traditional pull down screen that is found in many classrooms today. Instead of a screen being pulled down from the ceiling, fog is pushed down and held in place by several small fans, allowing for a consistent surface for display. The Fog Screen is an innovative display technology that allows for projections on a thin layer of dry fog. Imagine the traditional pull down screen that is found in many classrooms today. Instead of a screen being pulled down from the ceiling, fog is pushed down and held in place by several small fans, allowing for a consistent surface for display .

5. EXISTING SYSTEM A projection screen is an installation consisting of a surface and a support structure used for displaying a projected image for the view of an audience.

6. Some of existing systems are Rigid Wall Mounted Screens Pull Down Screens Electric Screens Switchable Projection Screen

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

8. Proposed System Fog Screen It is one type of advanced projecting device which consumes water and electricity to form fogs on which images are projected. The Fog Screen is a new invention which makes objects seems to appear and move in thin air! It is a screen you can walk through! The Fog Screen is created by using a suspended fog generating device, there is no frame around the screen.

9. Some of Fog screens

10. 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

11. Conti… After the screen is formed, images can be projected onto it. The screen can be translucent or fully opaque. The fog we are using is dry, so it doesn’t make you wet even if you stay under the Fog Screen device for a long time. The fog is made of ordinary water with no chemicals. With two projectors, you can project different images on both sides of the screen.

12. Applications Fog Screen 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 ). Create a luxurious interior with Fog Screen

13. 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. 

14. 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.

15. 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 .

16. SUCCESS OF FOG SCREEN Fog Screen has been successfully used in this international event : Entertainment (live shows, live concerts, nightclubs, stage productions, private parties i.e. Disney Enchanted Tour, Eurovision, Harrah’s, Cirque deSoleil , MGM Grand, 20th Century Fox) Brand promotions (P&G, Diesel, Victoria’s Secret. Bud light/Maxim Tour, Xbox ) Trade shows and exhibition events (Nokia, Motorola, Sony, Siemens ) Theme parks (Key US theme parks ) Museums and Science Centers

17. CONCLUSION Technology of the future literally revolutionizes the limits of projection screens and blurs the boundaries among art, science, and fun.
