'Holograms' will teach in British university

Imperial College London will use telepresence technology so that renowned professors can lecture and interact with students

Telepresence technology first began to be used in entertainment, in the military industry and in politics, and now it may have its best application in education. Imperial College of London plans to use telepresence 'holograms' for professors to give lectures to their students on a regular basis, first within their Business School.

This will simply be an improvement over the videoconferences that are already used in many universities. Teachers will have high-definition monitors so they can even look students in the eye and interact "really." While this technology is not exactly holographic, in practice it serves as such, creating drills, kind of holograms of people, similar to Pepper's Ghost effect, which has been used by the candidate for the presidency of France, Jean-Luc Mélenchon, to give a speech in seven different places at the same time.

Pepper's Ghost is extremely expensive, as it costs up to 150 thousand pounds per event, but what the British university will use, developed by a Canadian company called ARHT Media, will be cheaper, although it remains a strong investment. The idea is that teachers from different parts of the world can give lectures to their students.

The London university will be a pioneer in this type of implementation, which in some years could be more common, since it offers significant advantages (although not in cost) to videoconferences. That said, a face-to-face conference can hardly be overcome by a hologram or any other projection device.
