In the exhibition sector, multimedia presentations displayed with a projector onto a specially prepared surface are usually created in the form of an animation or a film that requires no interaction with the audience. In order to make the content of the presentation more attractive, it is worth using such solutions as interactive whiteboards. They allow users to create presentations not only to be watched but also engaged with through a touch screen. However, we can go a step further and instead of limiting ourselves to rectangular displays, use technology that allows to create a touch screen of any shape!
Touch projection screens – how does it work?
The solution consists of a projector, a screen, and an infrared-based system. The infrared searchlight directs light invisible to the human eye onto the screen, whereas detectors conduct observation of the surrounding area and detect interference. Then, using software, the interferences recorded by the detectors are processed into information about the user touching a specific fragment of the screen. Due to high flexibility and scalability of the solution, one can create a screen of any shape, size, brightness and equip it with as many touch points as the design requires. The only limitation is the budget.
Touch projection screen – use
Touch projection screens are a perfect complement to the architecture of the place. A semi-transparent image allows to achieve the effect in which a modern virtual world fits into the environment perfectly and becomes an integral part of it. Apart from the unusual look, the touch functionality makes the screens highly practical. A properly prepared interactive application perfectly complements the entire mechanism.
Touch projection screens – interactive applications
Unconventional projection screens require unconventional applications that would make the best use of their specificity. It is necessary to use appropriate technologies, and to make sure the graphic design harmonizes with the surroundings. This is described in more detail in the following article: modern interactive applications.
The technology of touch projection screens allows exhibitors to create phenomenal installations. Any shape can be processed into a projection that is interactive and controlled by the user. While it is indeed more and more difficult to surprise audiences and users of multimedia installations, in this case, an unusual screen, perfectly integrated into interior architecture, will create an unforgettable effect. Touch projection screens are a great example of how engineering, science and art can be combined.
