In Imperial College London, teachers will appear in front of students in the form of holograms. In this case, the lecture can go both in writing and in real time.
This was made possible by a special system from the company Arht Media, which equipped two studios in Los Angeles and Toronto. The teacher comes to this studio, where special cameras record what is happening. In front of him there is also a high-resolution screen on which the hall is broadcast with students: this is how the teacher keeps in touch with the audience.
And in the lecture hall itself, everything is simpler: the image is projected onto a glass screen with a special background: together with software, it creates the effect of depth.
For one performance with the Arht Media system, Imperial College London will spend about $ 1,300. If the same lecture is carried out using the Pepper's Ghost technique, it will cost the college $ 195,000.
The hologram solves several problems at once: lack of personnel, the inability to conduct a lecture in person and poor communication with the audience during simple video broadcasts.
