Comfort perception of the information. I have once said that reading the text – it is a stressful occupation, to the eye and the brain. It's a long process of concentration! Therefore, listen to information, certainly more comfortable, and usvaevaemost material is much higher, because the hearing did not need a focus and tension of the mind. If you ask anyone how way he would prefer to receive training: just listening to a lecture or reading it, I'm sure 80% will choose the plays, high credibility, which is achieved at the expense of emotion and easily transferable argumentation the author's voice. Despite the fact that copywriting (science writing advertising texts) came up with a bunch of ways to convey the emotional component, but it is not in what can not be compared with how to convey the emotional live voice. Often one notes enough to pass something that does not do any text with all its possibilities; enough low amount of information. Due to good compression of sound files which is achieved today through a new MP3, size and quality audio for the Internet is perfectly acceptable, even for poor Internet connections.
In addition, flash technology enables both play a part audio messages, and immersed in the buffer the next segment file. That is, you do not have to wait until load another piece of writing to him and then listen. This happens odnovemenno!; Easily create audio messages and Flash-Buttons. Again, if we consider the record, the preparation and installation of video recording and editing audio, the complexity of the process entirely different.
In many major metropolitan areas to our attention is constantly attracted by the huge led screen that not only are an ornament of the city, but also represent a source of information for its residents. led screens – video equipment capable of displaying information in large format for any lighting, both outdoors and indoors. Modern led technology allows a huge solid screens, without joints and so-called "seams" (modular build). Brightness, attractive led screens, their versatility and adaptability, ease of use, as well as a long services allow you to use them everywhere: in streets, concert halls, stadiums, sports complexes, etc. Commercials and informational text blocks can be broadcast simultaneously. Advertise on led video screens visible at a great distance, as used in these screens, bright LEDs can make the image visible even in bright daylight. Brightness – the main advantage of led screens because they are widely used in presentations and exhibitions as well as text, graphics, tables, clearly visible from the most distant seats of the auditorium, regardless of lighting in the room.
It may be noted several types of led screens: full-color led display screens, which use three-color matrix, so you can get a huge number of shades, as well as two-color led display screens, which have two-color matrix and reproduce a limited number of colors. Full-color led panel – it's advertising media on the street, the scenery at concerts, video screens at sporting events (scoreboards), etc. Two-color led display screens are used most often in the premises (sales rooms, presentations) to illustrate the text, graphics that do not require full-color image. The software can edit television programs and commercials during the rental period, overlay text on the video image, correct and supplement information. led screens can be both fixed and mobile. The latter can be installed on the mobile platform. Manufacture, sale, rental services, and their warranty and service are also invited and in our country.
