Researchers of the Swedish university Mittuniversitetet had constructed an interactive poster of paper that emits recorded sounds answering to the touch of the reader. The archetype uses conducting inks, that are sensible to the pressure and loudspeakers. The team of researchers affirms that the technology can be used for advertising executives and, in the future, can until being used to produce packings. The archetype presented for the researchers is an example of as the technology would help to vender packages of trips. “When you come close yourself to the poster and place its hand in a postal card that shows a beach, you it can hear a small description of that beach”, said to the BBC Mikael Gulliksson, who led the research project. Digital paper The secret of the falante poster is a layer of digital paper that has inlaid electronic components. The digital paper is printed matter with conducting inks, that, when they receive some type of pressure, transmit information for a microcomputer that contains archives of audio. The sound then is transmitted for loudspeakers that are printed matters in the paper, formed for more layers of conducting ink that are on of an empty socket forming a diaphragm. This functional layer is enters a thick cardboard blade and another sheet of paper that is printed with design of the poster. “The project pilot can be used for estandes in store and in other forms of propaganda”, Gulliksson said. Currently the posters are expensive, but the researchers aim at to find forms to lower the production costs so that it is more easy to change or to substitute the posters. In the future the team also plans to diversify the uses of the falante paper. “Our next idea is to discover as we can use this product in packings. An interesting idea would be to use in cigarette packages. Instead of a written message alerting of the perigos to its health, the message would be said”, said Gulliksson to the BBC.
