                    Holograms have already been used by politicians or scientists, such as Stephen Hawking (pictured), to give lectures from a distance.
                
            College classes are ready to take a futuristic turn by letting teachers appear in a hologram broadcast from afar. Imperial College London will showcase this technology at a special event on Thursday before starting to implement it widely. be the first academic body to do it on a regular basis. A similar effect has been used to animate images of Michael Jackson, Elvis Presley and other celebrities. Holograms that resuscitate the dead At first, the Imperial will limit its use to the activities of its business school but hopes that this technology will become common. "The alternative is to use videoconferencing software but we believe that these holograms offer a greater sense of presence," says the director of the center's Edtech Laboratory, David Lefevre, to the BBC.

                    The Imperial College of London ensures that the audience will be able to interact with the teacher.
                
            "The speakers have a high definition monitor in front of them that is calibrated so that they can address certain people and look them in the eyes, they can really interact," Lefevre explained. And more than one person can appear at the same time. In fact, at the Women in Tech event on Thursday, a panel will show two guests whose images will be broadcast from the United States along with two others who will be on stage. It is expected that the four may be able to communicate with each other. "Within the budget" Strictly speaking, the visual illusions are not holograms but neither are they the effect of the Pepper Phantom used by politicians such as the French presidential candidate Jean-Luc Mélenchon or the Indian prime minister, Narendra Modi; as well as the entertainment industry. Politicians who use holograms to be in 7 places at the same time instead use a technique developed by the Canadian company Arht Media.

                    Mélenchon was one of the politicians who used holograms. Can you tell which of these images is an illusion and which one is the original?
                
            "The problem with the Pepper Ghost is that it can be complicated to assemble and it can cost around £ 150,000 (about US $ 195,635) to organize an event," says Lefevre. "This is simpler: projecting on a glass screen and a background behind it uses software to give the illusion of depth, "he said. And according to Lefevre, technology" costs a few thousand dollars, so for the first time universities can afford it. " To send their image, the speakers need to use a "studio", in which to film them on a black background while they are illuminated on both sides. Imperial College plans to use two external studies: one in Los Angeles and the other in Toronto, as well as a portable kit to invite people abroad to give talks to their students. In addition, he will try to use his equipment for one of his professors to make a presentation at a school of economics in Spain in February.

                    Imperial can set up a "studio" in other places to attract guests from all over the world.
                
            Beyond providing a more practical solution to attract foreign talent (instead of having to move them to London), the university ensures that there are more advantages. A popular guest can give the same talk in different rooms at the same time. They will be recorded and retransmitted later, although in this case the interactions with the audience would be left out. The disadvantage of this system, however, is that it is less likely that the guests will stay to chat with people in the audience when their conference ends. In addition, there is always the possibility that there is a technical problem. However, the Imperial is convinced that the advantages outweigh the disadvantages. "It is going to become one of those technologies that is used the most," predicts Lefevre. As long as the technology works as we think it will, I think this will become the main trend, "he predicted.
