A fog screen is one of the most original and impressive innovations in the projection technology market. When a visitor sees the result of such equipment for the first time, it creates the impression that an object appeared in the air out of nowhere. But in reality, this is not the case. The image is projected onto a screen made of an almost invisible stream of fog. It is not possible to feel it physically. Walking through it, one can feel a pleasant coolness. The fog screen operates noiselessly, its base is invisible, yet it creates stunningly bright and clear video that seems incredibly realistic.
Modern fog screens, or PoliVizors, have found widespread application today. They are in demand in:
advertising and media;
entertainment, including nightclubs, theaters, concerts, and television shows;
organizing exhibitions, presentations, and promotional events;
celebrating anniversaries, weddings, birthdays, and corporate meetings.
Is the air screen tangible or not?
Everyone who sees a PoliVizor for the first time wonders how the image is created and whether it is a projection or a tangible object. The initial reaction is always awe and surprise. Such a show always attracts many eyes and becomes the center of attention even in a large exhibition complex, being perceived as an extraordinary performance.
It seems as though the image is three-dimensional, floating in the air without any support. But when trying to pass through the screen, only dryness and coolness are felt. Why? Because the image is projected onto a stream of fog, consisting of the tiniest water droplets forming a three-layer thin layer.
The technology of the fog screen is unique and spectacular. Admit it, it’s not every day that you walk into the office of a large company or institution and see an object floating in the air. Not long ago, this technology was a fantasy, but the diligent work of specialists worldwide has made the PoliVizor a reality.
The system itself is economical and quickly pays off. Essentially, the screen is made of ordinary water, which is delivered via pneumatic systems in the form of the tiniest droplets with a negative charge. This ensures that water particles do not clump together into large drops, and the screen acquires the necessary properties. The particle size is only a few microns, and they are generated by a special device similar to a conventional humidifier. However, no humidity is felt during the screen's operation, though this does not mean the moisture instantly evaporates.
For rooms where a PoliVizor is installed, there are several restrictions:
A dehumidifier must be present in the room and placed at the farthest point from the screen.
Strong drafts or air conditioning flows must not affect the screen.
The ceiling height in the room must be at least 3 meters, as the working height of the air screen surface will only be about one and a half meters.
Some dimming must be provided to ensure the image is as clear as possible.
PoliVizors should not be used in rooms filled with tobacco or disco smoke.
Capabilities of the fog screen
Steam projection can be used for various purposes. The potential of this technology is vast, finding applications in advertising and education.
The air screen is applicable for the following purposes:
In addition to high-quality visual imagery, which appears three-dimensional to viewers, there is also the option to use sound. It is fully synchronized with the image. Special fragrances can be added to the water reservoir, which is the consumable material for creating the screen. During the operation of the system, a light, but pleasant aroma can be sensed. The choice of fragrances depends entirely on the focus of the advertising campaign. For instance, food products are showcased with scents that match the advertised product. In other cases, experienced marketers choose scents that viewers will associate with the product, evoking memories of it later. This is a crucial and responsible step that can influence the outcome of the entire campaign. It should be remembered that a single fragrance is needed to demonstrate the product, and to change it, the system must be turned off, the water tank flushed, and a new fragrance added. All of this requires the involvement of experienced marketers.
The PoliVizor has a rich functionality, and its use is usually limited only by the user’s imagination. However, it is important to remember that there are certain limitations. For example, the fog screen cannot replace a regular computer monitor, and it is not suitable for watching movies or TV shows. Although the image on the air stream has good resolution, it still falls short compared to projection and holographic systems.
PoliVizors are most often used as standalone advertising tools. They are installed as displays. Simply turning on the system allows it to begin its highly effective operation. Many hotels and entertainment venues use PoliVizors as curtains at the entrance. Instead of a regular door, a dynamic image or logo floats, and one can easily walk through this screen without encountering resistance. The effect is stunning.
Fog projection screens can also be used for other purposes, such as in scientific and educational centers during conferences. As the equipment becomes more accessible, its use expands beyond just advertising activities.
New technologies always attract attention, so don’t miss the opportunity to stand out among your competitors. This innovation will appeal to almost any age group.
