80 students from all around the globe are displayed on a curved screen measuring 45 square metres. The lecturer is a hologram moved around the lecture hall by a robot. The students collaborate on documents and take part in simulations in real time. The professor uses artificial intelligence and big data to run simulations that test the students’ abilities. He or she has a rolling live feed of data on students’ participation, including their emotional engagement. There is no back row of seats where students can hide. Everybody sits front and centre on the giant screen.
